ABSTRACT: A field experiment was conducted in Krishi Vigyan Kendra, Deendayal Research Institute, Satna for two consecutive years to evaluate the effect of various in- situ moisture conservation measures on establishment and growth of aonla in sloppy degraded lands. In-situ moisture conservation measures included for the study were preparation of circular ring basin + mulching the basin with black polythene, staggered contour trenching 45 cm width and 3 m length) on upper side of the plant basin, placement of one submerged pitcher in one side of the plant for rainwater harvesting, setting the seedling in a depression of 1 m width and 15 cm deep, surrounded by a ring-shaped ridge with 25 cm width and 15 cm height and a 30 cm opening on the higher side to harvest rain water + filling the depression with straw + mulching with black polythene and control (no micro- catchment or mulch). The data on growth parameters (scion shoot length and diameter; number of branchlet, number of leaves, leaf area, fresh and dry weight of shoots and roots) and nutrient content of leaves of budlings under the five treatments were recorded. The results revealed that planting one month old polythene raised seedlings in a pit depression of 1 m width and 15 cm deep, surrounded by a ring-shaped ridge with 25 cm width and 15 cm height and a 30 cm opening on the higher side to harvest rain water and filling the depression with straw and covering the pit with black polythene and performing patch budding next year during end of June, which resulted in maximum budling growth, and nutrients uptake observed to be the best in situ moisture conservation method and may be recommended for rehabilitation of degraded sloppy lands.

Department of Soil & Water Conservation Engineering G. B. Pant University of Agriculture & Technology, Pantnagar–263 145 *E-mail: [email protected] ABSTRACT : The study was carried out at the College of Forestry & Hill Agriculture, Hill Campus, Ranichauri, Uttarakhand. Soil moisture content was measured using gravimetric method periodically in 0-15, 15-30, 30-45 and 45-60 cm soil profiles. Field experiments were conducted on cauliflower (Brassica oleracea) crop during 2007-08 and 2008-09. The crop was transplanted in October and harvested in February spanning 100 and 99 days, respectively. Four irrigation treatments were maintained based on the maximum allowable depletion (MAD) of available soil water. The treatments were 15% (T1), 30% (T2), 45% (T3) and 60% (T4) maximum allowable depletion of available soil water. No water stress was maintained at the initial stages of the crop development in order to allow the plants attain a healthy growth. Results revealed that irrigation schedule with 45% maximum allowable depletion of available soil water gave the maximum water use efficiency for cauliflower crop. It was found that for scheduling of irrigation for cauliflower crop 0-30 cm soil profile should be considered as most of the water was found to be extracted from this layer by the plant..

Rachna* and Sukhdev Singh

Department of Horticulture, Faculty of Agriculture and Forestry, Khalsa College, Amritsar-143003, Punjab *E-mail: [email protected] ABSTRACT: The present studies aimed at evaluating the effects of varying doses of GA3 on the bio-chemical changes of ber fruit during development. GA3 @ 10, 30 and 50 ppm was applied at fruit set stage and then superimposed one month thereafter. The periodical bio-chemical analyses of developing ber fruits revealed that total soluble solids concentration increases maximum during initial stages of fruit development i.e. between interval of 25 to 50 days of GA3 application while total sugars and ascorbic acid increase and acidity decreases as the fruit reaches maturity i.e. between 75 to 100 days of GA3 application. The GA3 50 ppm dose resulted in maximum expression of acidity, total sugars and ascorbic acid at final harvest of ber. Thus it is implicated that GA3 application is beneficial in improving flavour and taste of ber.

N. Vijaya Kumari* and M. Lakshmi Devi

Department of Sericulture, Sri Padmavati Mahila Visvavidyalayam, Tirupati-517 502, Andhra Pradesh *E-mail: vijji [email protected] ABSTRACT: Root knot disease caused by the nematode Meloidogyne incognita is one of the major diseases of Mulberry, Morus spp. which causes major reduction in yield affecting both quality as well as quantity of leaves and fruits. Plants produce a high diversity of secondary metabolites for self defense and survival in their habitat. Some of the plants are known to be inhibiting the development of the nematodes. The present study was carried out to screen the locally available plants for their nematicidal activity. Twelve plants species were selected and methanol extracts with different concentrations (25, 50, 75 and 100%) of different plants were tested for inhibition of hatching of M. incognita egg and juvenile mortality in different durations. The plant extracts of Neem, Clitoria ternatea and Passiflora foetida were recorded to be highly effective for inhibition of hatching of egg and increasing juvenile mortality of M. incognita. Which will be immense helpful to reduce the qualitative and quantitative loss of mulberry leaf and fruit with eco-friendly plant extract.

Department of Horticulture, Chandra Sekhar Azad University of Agriculture and Technology, Kanpur (U.P.) *E-mail : [email protected]. ABSTRACT: An experiment was laid out during two consecutive years in Horticulture garden of Chandra Shekhar Azad University of Agriculture and Technology Kanpur. There were three nitrogenous sources viz. urea, ammonium sulphate and calcium ammonium nitrate, four levels of nitrogen viz. 0, 50,100 and 150 kg/ha and four levels of phosphorus viz. 0,100,200 and 300 kg/ha, thus a total of fourty treatments were taken. The results showed that emergence of skipe under the influence of N sources ranged from 97.27-98.35 and 95.58-97.91 days during first and second year of study. Calcium ammonium nitrate caused 1.08 and 2.33 days earlier spike emergence than urea treatment. Nitrogen applied@ 150kg/ha proved more effective in delaying spike emergence but 300kg/ha phosphorus induced earliest emergence. Length and width of spikes was improved with ammonium sulphate followed by CAN recorded 78.19 and 80.99 cm long and 0.88 and 0.90 cm thick spikes, respectively. Nitrogen applied @150 kg/ha caused 78.16 and 81.14 cm length of spike and 0.88 and 0.89 cm thick spikes in first and second year, respectively. Length of rachis was registered 1.45 and 1.65 cm longer under ammonium sulphate. 150 kg nitrogen per hectare maximized length of rachis (26.74,27.85 cm) whereas, phosphorus @ 300kg/ha revealed maximum (26.26 and 27.38 cm) length of rachis. Number of flower maximum influenced by CAN revealed 39.69 and 40.83 flowers during both years. Nitrogen @ 150kg/ha maximized (40.80 and 41.20) number of flowers. Fertilization with calcium ammonium nitrate exhibited longest blossoming duration. Durability of spike increased consistently with increase in nitrogen levels up to 150/ha dose recording 21.41, 22.39 days duration during both experimental years. Phosphrous @ 200kg prolonged self life by 3.46 and 2.67 days when compared with control registering 20.89 and 22.33 days durability.

Ramesh Singh* and N.S. Sachan¹ Department of Plant Pathology, T. D. (P.G.) College, Jaunpur ¹Oil Seed Section , C.S.A. Univ. of Agri. & Tech., Kanpur *E-mail: [email protected] ABSTRACT : Biological control involves the use of beneficial organism, their gens, and/ or products, such as metabolites, that reduce the negative effect of plant pathogen and promote positive response by the plant. Disease suppression, a medicated by bio-control agents, is the consequences of the interactions between the plant, pathogen and microbial community. Mycoparasitism, spatial and nutrient competition, antibiosis by enzymes and secondary metabolites and induction of plant defense system are typical bio-control action of these fungi. Faster metabolic rates, anti-microbial metabolites and physiological conformation are key factors which chiefly contributes to antagonism. V.A. Mycorrhizae play major role in biological control of plant diseases owing to their capabilities of amelioration crop yields by multiple role as bio-pesticides and plant growth promotion.

1. GAP: NON MONETARY WAY TO MANAGE FABA BEAN DISEASES—A REVIEW Anil Kumar Singh* and Vijai Kr. Umrao1 ICAR Research Complex for Eastern Region, Patna 800 014 Bihar 1 Department of Horticulture, CSSS (PG) College, Machhra, Meerut-250 106 (U.P.) *E-mail: [email protected]

ABSTRACT: Faba bean (Vicia faba L.) is, among the oldest crops in the world, attacked by a wide range of pathogens although each of these diseases is quite destructive, when two or more interact on the same plant, their combined effect becomes greater. Good agronomic practices are in general non monetary interventions, discussed here under suitable heads, which can be easily adopted by the farmers to manage faba bean disease smartly. It is an efficient and excellent tool for effective disease-pest management in general and especially for soil borne pathogens and diseases like chocolate spot,ascochyta blight and rot etc.

2. INFLUENCE OF POSITIONS OF BEARING AND METHODS OF HARVESTING ON THE QUALITY OF FRUITS–A REVIEW Priyamvada Pandey*, Rajesh Kumar, Ayushi Tamta and D.S.Mishra Department of Horticulture,G.B.P.U.A. & Tech., Pantnagar

*Email: [email protected]

ABSTRACT:India is blessed with varied climatic conditions and is thus the home of various types of fruits. But most of the fruits are highly perishable and show a great decline in quality as well as storage life soon after harvest. This decline is further aggravated if harvesting is not done at the right time and by the correct method. Moreover position of bearing also plays a key role in the quality of fruit. Fruit position on tree is found to influence the fruit size, maturity, skin colour, flesh colour, mineral composition, TSS, acidity and fruit yield. Harvesting fruits with and without pedicel in addition to affecting the storage life of fruits, also affects sugar content, acidity, fruit firmness and colour retention. This review summarises effects of positions of bearing and methods of harvesting on the overall quality of fruits.

3. STATUS OF DRY MATTER AT HARVESTING STAGE IN COMMERCIALLY GROWN GRAPE VARIETIES UNDER TROPICAL CLIMATIC CONDITION R.G. Somkuwar*, Roshni R. Samarth, J. Satisha, S.D. Ramteke and Prerna Itroutwar National Research Centre for Grapes, P.O. Box No. 03, Manjri Farm Post, Pune 412307 * E-mail:[email protected]

ABSTRACT: The experiment was conducted at NRC for Grapes, Pune during year 2007-08.Four commercially cultivated grape varieties viz. Thompson Seedless, Tas-A-Ganesh, Flame Seedless and Sharad Seedless were analyzed for dry matter content during harvesting stage of the crop. Dry matter partitioning in different parts of vines were observed. Highly significant differences were observed among varieties, various vine parts and their combinations. Among the varieties, maximum dry matter content was recorded in Sharad Seedless (42.87%) followed by Tas-A-Ganesh (42.29%) and among the various parts of the vine, it was found maximum in cordon (54.84%) followed by trunk (54.39%). When dry matter content was measured in particular variety in specific part of the vine, maximum dry matter was recorded in the trunk of Sharad Seedless variety. Roots are the source of nutrient absorption by the vine. Root health found to be positively correlated with the health of the plant and productivity. In the present experiment, highest dry matter content of the roots was observed in the Sharad Seedless with the mean value of 47.72%. Also the dry matter content of the harvestable organ (bunches) was found maximum in Sharad Seedless (25.73%) as compared to other variety.

Erode

(1)

Selection-1. All the intercropping systems showed significant enhancement in the height of the tree varying from 1.25 to 3.40 over the sole tree. Among the different intercrops, better growth of the guava tree was observed where mother rhizome turmeric was grown as intercrop followed by primary, secondary and tertiary fingers treatments. Plant height and number of tillers per plant were enhanced in mother rhizome of turmeric (96.68 cm and 4.03, respectively) under shade of guava plant which results maximum survival percentage (98.45%) and its growth and performance was better than other planting materials. The highest number of fingers per plant (13.64), finger length (9.06), finger weight (36.14) and yield (389.47g/plant and 235.41q/ha) were recorded when turmeric were grown under juvenile guava tree which was significantly higher than all other planting materials. All the turmeric planting materials grown under shade of juvenile guava orchards were found most desirable in terms of vegetative growth, yield, gross return, net return and benefit cost ratio than sole crop.

5. OPTIMIZATION OF PLANTING DENSITY IN CARNATION S. Karthikeyan* and M. Jawaharlal

Department of Floriculture & Landscaping, Horticultural College & Research Institute, Tamil Nadu Agricultural University, Coimbatore-641 003, Tamil Nadu, India. *E-mail: [email protected] ABSTRACT: The experiment on optimization of plant density inside a greenhouse for growing carnation is a very important area for present day production and productivity. The results of the study on optimization of planting density in carnation led to the inference that planting density in treatment T4 (check) (15 X 15 cm with 36 plants/m2) proved better in terms of flower quality parameters namely early flower bud appearance, bud opening, longest duration of flowering, chlorophyll content and more number of flowers per plant due to congenial microclimate between the plants for the plant growth and flowering. Though the percent age of ‘A’ grade quality flowers were higher in treatment T3 (20 X 20 cm with 20 plants per m2), the number of plants and flower yield per sq. m. in this treatment was very less. Hence, treatment T4 (check) with 15 X 15 cm spacing may convincingly be followed for obtaining more number of flowers per plant and per unit area and value in terms of economic success of the crop.

19. EFFECT OF WEEDICIDE IN MINIMIZATION OF WEED MENANCE IN NAGPUR MANADARIN ORCHARD J. Singh*, P. Bhatnagar and Bhim Singh College of Horticulture & Forestry (MPUAT), Jhalrapatan, Jhalawar - 326023 (Raj.) *Email: jsingh [email protected].

ABSTRACT: During Kharif season weed poses serious threats in mandarin orchards and sometimes the infestation of weed flora is so high that it creates great challenge in maintaining the plant growing and surviving properly. To counter weed problem, weedicides have proven its worth. Labour availability getting problematic day by day, option of weed control rests with the view of weedicide with such an idea an experiment was conducted with a view to assess the efficacy of weedicide in countering weed growth in newly grown mandarin orchard. The orchard was having heavy infestation of Echinocola cholena, Celosia sp, Cassia tora, Comelina communis, C. benghalensis, Abelmoschus muschatus, Euphorbia xeniculata, Parthenium hysterophorus, etc. From the experiment it appeared that Isoproturon 75% WP@ 2% was found most efficacious out of 2, 4-D , Oxyflourfen, Glyphosate and Imazethapyr used to control weeds in mandarin orchard.

1. Effect of LEDs on flower bud induction in Chrysanthemum morifolium cv. Zembla Mam C. Singh1*, Wim van Ieperen and E.P. Heuvelink

Horticultural Production Chains Group, Plant Sciences, Droevendaalsesteeg-1, 6708 PB Wageningen,Wageningen University, The Netherlands 1 Present address: Centre for Protected Cultivation Technology, I.A.R.I. Pusa Campus, New Delhi-110012, India *E-mail: [email protected] ABSTRACT: The effect of LEDs was studied to induce flower under artificial long days (LD) in Chrysanthemum morifolium cv. Zembla plants, using light emitting diodes (LED) @ PAR m-2 s-1 80% Red / 20% Blue maintained @ 100 µ mol m-2 s-1 using royal blue light @ 455 nm and red light @ 640 nm wavelengths and compared with short day (SD) length. Difference in growth and flowering response were also investigated. Stem length is determined as a function of internode length which could be the function of attaining minimum number of leaves required for expressing the diurnal response using LEDs. Chrysanthemum plants exhibited a strong diurnal response attained in leaves and transmitted to the apex and took minimum (28 days) and maximum time (61 days) with an exposure to LEDs with (15h) and without (11h) additional blue spectrum, respectively. However, bud induction was possible earliest due to low red/far ratio in the extended exposure of plants with blue LEDs.

2. Effect of different levels of nitrogen, phosphorus and potash on growth and flowering of Chrysanthemum cultivars N.S. Joshi, A.V. Barad*, D.M. Pathak and Nilima Bhosale Junagadh Agricultural University, Junagadh (Gujarat)-362 001 *E-mail : [email protected] ABSTRACT: Field experiments were conducted for two consecutive years on medium black calcareous soil of Horticultural Instructional Farm, Junagadh Agricultural University, Junagadh. The experiment was laid out in factorial randomized block design with twenty four treatments replicated three times. The treatments consisted of two varieties of chrysanthemum viz., IIHR-6 (V1) and Shyamal (V2), three levels of-1nitrogen (100, 200 and 300 N kg ha-1), two levels -1of phosphorus (100 and 150 P2O5 kg ha ) and two levels of potash (100 and 150 K2O kg ha ). Both the varieties significantly influenced growth and flowering parameters, where, plant height, number of branches per plant and leaf area were observed higher in the variety IIHR-6 during both the years and in pooled results; whereas higher fresh and dry weight of plant, weight of 10 flowers, flowering span and dry weight of flowers were recorded in the variety Shyamal. The later variety also took more days for first flower bud initiation and first flower open. Application of nitrogen at 300 kg ha-1 recorded significantly highest plant height, number of branches per plant, leaf area, fresh and dry weight of plant, flowering span, total fresh and dry weight of flower, weight of 10 flowers and di ameter of flower during the first year, second year and in pooled data. The dose @ 300 N kg ha-1 also took less days for first flower bud initiation and first flower open. Phosphorus also played a significant role in improving all of these attributes at higher level except, leaf area, fresh weight of plant, number of days taken for first flower open and flowering span. Effect of potash was failed to influence all of these growth and flowering parameters during both the years and in pooled results also.
