    STANDARDIZATION OF THE DOSES AND TIME OF APPLICATION OF ‘JEEVAMRIT’’ IN WHEAT UNDER NATURAL FARMING SYSTEM
    (CSKHPKV, Palampur, 2019-05-27) Kaur, Puneet; Saini, J.P.
    A field experiment was conducted during Rabi 2017-18 at Holta organic farm of Department of Organic Agriculture, CSK HPKV, Palampur to standardize the doses and time of application of „Jeevamrit‟ in wheat under natural farming system. The experiment consisted of 10 treatments comprising of application of jeevamrit @ 5 per cent at 2, 3 & 4 weeks interval (T1, T2 & T3), jeevamrit @ 10 per cent at 2, 3 & 4 weeks interval (T4, T5 & T6), jeevamrit @ 20 per cent at 2, 3 & 4 weeks interval (T7, T8 & T9) and vermicompost @ 10 t/ha + 3 sprays of vermiwash @ 750 l/ha (T10). The basal application of Ghanjeevamrit @ 250 kg/ha + sieved FYM @ 250 kg/ha was done in all the plots except T10, at the time of sowing. Significantly higher grain yield (3117 kg/ha) was recorded with application of jeevamrit @ 20 per cent at 2 weeks interval (T3), which was at par with T2 (2967 kg/ha), T6 (2958 kg/ha), T10 (2891 kg/ha) & T5 (2861 kg/ha). However, significantly higher net return was recorded in T2 (Rs 54906/ha), which was at par with T5 (Rs 53875/ha), T3 (Rs 53251/ha), T6 (Rs 52225/ha), T1 (Rs 47785/ha), T9 (Rs 47843/ha) & T8 (Rs 47223/ha), however comparatively higher net return per rupee invested was recorded in T5 (1.69), which was also at par with T2 (1.61), T7 (1.57), T8 (1.57), T4 (1.54), T1 (1.54) & T9 (1.45), respectively. Microbial studies revealed that significantly higher colony forming units (cfu) of bacteria (32.69 × 106), fungi (24.86 × 103) and actinomycetes (6.02 × 102) per gram of soil were recorded in T3, which was at par with T2 (30.68 × 106, 23.18 × 103, 5.56 × 102) & T6 (29.34 × 106, 22.33 × 103, 5.55 × 102) cfu/g soil. Whereas, higher soil organic carbon (0.80%) was recorded in check (T10), which was at par with T3 (0.79%), T2 (0.77%) & T6 (0.76%) and higher available NPK (220.8, 36.6 and 200.6 kg/ha, respectively) were recorded in check (T10) after the harvest of crop.
