On-Going Projects

  • ICAR sponsored Niche Area of Excellence Project on Production and protection Technologies for Potential Vegetables & Pulses under Organic Farming System

Accomplishments

Varieties:

  • Out of the recommended varieties of the university for different crops, Early Composite (30-32q/ha) of maize, HPW 155 (20-25q/ha), HPW 249 of wheat, RP 2421(20-22q/ha) of Rice,  Surbhi (8-10q/ha), Him Alsi 1(8-10q/ha) of Linseed , Sheetal (10-15q/ha) of Gobhi Sarson.

  • Three genotypes of wheat (HPW-349, PW-974 and PW-972), 5 of maize(LM-40-2,LM-41-2, LM-13-11 & LM -02-08), two of soybean (VLS-63, P-16-1-12) and two of rice (Taichu dhan, Sukara dhan) have been identified for organic condition. All these genotypes are in advanced stage of testing for yield and related traits.

Nutrient management:

  • Various ITKs based organic inputs viz. Vermicompost, Himcompost, enriched/ BD compost & Nadep composts among solid organic composts and Vermiwash, Himsol, Matka Khad, CPP, Compost Tea, Biosol among liquid manures were prepared. The processes during compost preparation – component material decomposition, enrichment and fortification were standardized by use of local farm material (biomass of various weeds, cow urine, sheep/goat droppings, banana leaves), organic sources of nutrient (Gypsum, rock phosphate, Patent kali, bone meal, Oilseed cake etc.) and various bio-inoculants, Nitrogen fixers, Phosphorus  solubilizers and locally isolated and evaluated Trichoderma strains ) were standardized, composts/manures analysed and finally tested in the fields for their comparative efficacy in nutrient management.

  • Amrit Pani, Jeevamrit, Bijamrit, Panchgavya, Matka Khad etc. were analyzed and validated for their role in soil enrichment/treatment and seed treatment in organic farming. Liquid manures were evaluated for their periodic sprays on the standing crops to meet out their nutrient requirements at various stages of growth.  All the composts and manures were found to be most effective in combination rather than in isolation. Their rates of application in different indicator crops were evaluated. Vermicompost + enriched compost was found to be the best.

  • Liquid manures were found to be enriched with enough number of those microbes which help in nitrogen fixation & phosphorus solubilization and also growth regulators.

  • All the composts were studied in isolation and in combination with various bio-fertilizers prepared in the department. Application of enriched compost (Himcompost) 5.0 t/ha or V.C. 10.0 t/ha along with biofertilizers and bioagents (Azospirillim, Azotobactor, P-solublizers and Trichoderma ) resulted in significantly higher yields in major indicator crops.

Plant Protection:

  • Integration of various organic practices by following the four  basic principles of Organic farming resulted into reduced insect-pests and disease incidence and reduced disease severity  in various indicator crops in the organic Farm.

  • More than 30 plant extracts, 12 biopesticides and 25 cow substrate based organic inputs were evaluated in laboratory and in the field in different crops and against insect pests and diseases. Among them, seasoned cow urine + fermented butter milk @10%, Panchgavya 10% (screened as prophylactic plant protection measure), Polygonum hydropiper (Ghaniri) 5% extract against Mustard aphid, Lipaphis erysimi, NPV (Ha) @ 3×1012 POBs against Gram Pod Borer, Helicoverpa armigera in chickpea, Melia azadirach 5% extract against pea leaf miner, Red Pumpkin beetle and fruit fly in summer squash, fermented butter milk+turmeric+asafoetida against powdery mildew of Pea, , Neem Seed Kernel Extract 5% at 10 day interval to manage fruit fly and red pumpkin beetle in cucumber crop, soil applications of Metarrhizium aanisopliae and Bacillus cereus against bean bug and blister beetles in pulses, respectively were found effective under organic conditions. Ten microbes isolated from different plant formulations were found effective against seven soil borne plant pathogens. An organic input containing biosol, cow urine and CPP was found very effective against bacterial wilt of solanaceous crops

  • Dry powders of various plant leaves, edible oils and other organic inputs were tested against storage pests in Peas and mash. The leaf powders of Citronella, Eucalyptus each @ 4g/kg, while mustard oil @ 8ml/kg and Akshvaan as cow substrate based input @ 3ml/Kg of seed were found effective. Ethanol extract of Psudomonas fluorescence against leaf spot disease in tegetes, Eupatorium, CPP, Bijamrit also improved significantly germination percentage and reduction of seed borne diseases. Over 20 isolates of bioagents including Trichoderma were also tested. 

SALIENT ACHIEVEMENTS 2014-2015

  • Out of the 14 genotypes of mash DKU-95 significantly out yielded the best check i.e. Palampur -93 giving higher yield  12.70 q/ha, whereas, among 10 genotypes of soybean tested under organic input conditions VLS-63 significantly out yielded best check giving higher yield 21.56 q/ha.

  • In vegetable-legume based cropping systems Cowpea – Garlic and Soybean–Garlic systems produced 141.3 and 139.5% higher soybean equivalent yields, respectively as compared to Cowpea–Onion cropping system. In an another study Okra–Gram system produced highest equivalent yield (113 q/ha) followed by Okra – Pea (104.4 q/ha).

  • For nutrient management in mash, vermicompost @ 5t/ha+biofertlizers (Rhizobium+PSB)+3 applications of liquid manure (vermiwash) at 15 days interval commencing from 20 days after sowing produced 62.5% higher mash yield as compared to the control (FYM @ 5 t/ha). However, in the absence of biofertilizers and liquid manure vermicompost 10 t/ha should be applied at the time of sowing to meet out the nutrient requirement of mash.

  • For the management of blister beetle menace in mash, Lantana dust 10% (grinded leaves) and neem baan 3ml/l were most effective and provided 100% protection against blister beetle.

  • For the management of flea beetle infesting okra crop Neembaan @ 3ml/l was found to be the most effective in the range of 69.35__90.22% followed by Lantana dust 10% where efficacy was in the range of 63.60-86.95%.

  • In soybean, neem oil (Neembaan) @ 3ml/l was most effective in the range of 68.21-93.47% followed by neem seed kernel extract 5% with  59.07-86.60% efficacy for the management of Riptortus bug.

  • Aeration of vermiwash for 4 hours resulted in significantly higher (62.4%) onion seed yield as compared to the control.

  • In onion-soybean cropping system application of Himsol (liquid manure) produced significantly higher onion equivalent yield (82.56 q/ha) as compared to the control (62.59 q/ha).

  • In cereals-legume based cropping systems, Maize+Soybean-Wheat+Gram and Soybean-Wheat+Gram systems being at par with each other were observed to be the higher yielders and remunerative as compared to the other evaluated systems.
