Field bean – Application offish nutrient solution @ 2.5% vegetative + 5% flowering +2.5% pod development stage- Pod yield (17.25 q/ha) and 13.79 q/ha seed yield.

Bhendi / Lady’s finger / Okra – Maximum mean fruit yield (83.38 q/ha) was found in the treatment applied with panchagavya @ 3% at vegetative stage + Jeevamrutha @ 5001 / ha at flowering stage.

  • Field bean – Maximum pod yield (12.96 q/ha) and seed yield (10.37 q/ha) was recorded with fish nutrient solution applied @ 2.5% at vegetative +5% at flowering + 2.5% pod development stage.
  • Scientific validation of Zero budget natural farming (ZBNF) at RIOF, Bengaluru The analytical studies of Beejamrutha&Jeevamrutha liquid organic manure was done at RIOF and Beejamrutha is used for seed treatment and is alkaline pH (8.00), with 2.38% N, 0.127%  485  Fe-168 ppm, Mn-16 ppm, Cu- 36 ppm & Zn-18 ppm nutrient content. It has to be used on day of its preparation. Jeevamrutha liquid organic manure is used as nutrients in crop production. This is acidic in nature (4.85) with 1.96% N, 0.173%   0.280  Fe-318 ppm, Mn – 46 ppm, Cu – 51 ppm & Zn-12 ppm nutrient content. Also Beejamrutha&Jeevamrutha is rich inmicroorganisms viz., beneficial bacteria, fungi, actinomycetes, N-fixers and P-solublizers. Jeevamrutha has to be applied at 7 days – 10 days of its preparation, where microbial load will be at highest range.
  • Biodigester is a structure / unit to prepare liquid organic manures in large quantity using animal wastes like dung, urine and various organic agricultural wastes. From the various studies conducted at various Agriculture Research Stations of UAS (B), it was found that the bio digester tank is the suitable tool for the production of large quantities of liquid organic manure using animal wastesand crop residues/wastes/weeds etc., Package of Practices has been developed for Finger millet, Maize, Redgram and Groundnut by using liquid organic manures viz., Biodigester liquid organic manures &Jeevamrutha.
    1. Organic finger millet production

  • Similar studies to develop organic package on use of various organic sources in combination with liquid organic manures is being evaluated in oil seed crops like sunflower, groundnut, niger and sesamum.
  • Developed one acre model on organic vegetable production at RIOF field unit, UAS, GKVK, B-65.
  • Evaluation of different oilcake extracts for biofertilizers production– With the concern of successful production of biocontrol and bioagents by using locally available oilcakes viz., ground nut, neem and pongamia were found to show higher shelf life of all the biofertilizers and biocontrol agents till 60 days after inoculation. The addition of Glucose at 1% has resulted in higher microbial count than without glucose. Neem followed by groundnut and pongamia has shown better shelf life of microorganisms and hence these oilcakes are better alternative for farmers to mass multiply local.
