Abstract
A field experiment was conducted during Rabi 2016-17 at Model Organic Farm of Department of Organic Agriculture, CSK HPKV, Palampur to study the effect of liquid organic manure ‘Jeevamrit’ on the productivity of wheat under zero budget natural farming system. The experiment consisted of 10 treatments comprising of sole drenching of jeevamrit (at sowing – T1, at sowing + 30 DAS – T2, at sowing + 30 + 45 DAS – T3 and at sowing + 30 + 45 + 60 DAS – T4), application vermicompost @ 7.5 t/ha at sowing along with jeevamrit drenching (at sowing – T5, at sowing + 30 DAS – T6, at sowing + 30 + 45 DAS – T7 and at sowing + 30 + 45 + 60 DAS – T8) and sole application of vermicompost @ 7.5 t/ha – T9 and vermicompost @ 10 t/ha (check) – T10.Significantly higher grain yield was recorded in T8. 16.16, 8.99, 3.36 and 2.16 per cent higher grain yield was recorded in T8, T7, T4 and T3 over check, respectively. However, significantly higher net returns (₹72,389 and ₹ 72814 /ha) and net returns per rupee invested (2.88 and 2.76) was recorded in T3 and T4, respectively. Microbial studies revealed that significantly higher colony forming units (cfu) of bacteria (23.72 × 106), fungi (17.31 × 103) and actinomycetes (3.66 × 102) per gram of soil sample were recorded in T8, which was better than rest of the treatments. Whereas, higher soil organic carbon (1.44%), available NPK (279, 38 and 206 kg/ha, respectively) were recorded in check, which was on par with T9, T5 and T6, after the harvest of crop.
