    Response of organic sources of nutrients in blackgram
    (palampur, 2022-08-24) Sachin; Singh, Janardan
    A field experiment was conducted at Model Organic Farm, Department of Organic Agriculture and Natural Farming, CSK Himachal Pradesh Krishi Vishvavidyalaya during the Kharif season of 2021, to evaluate the effect of organic sources of nutrient on growth and yield of blackgram. The experiment was laid out in randomized block design comprising of eight treatments [T1 − Bijamrita + Jiwamrita (5%, 10%, 10%, and 10%, respectively at time of sowing, 21, 42 & 63 DAS) + Mulching (10 t/ha), T2 – Bijamrita + Ghanajiwamrita (250 kg/ha) + Mulching (10 t/ha), T3 − Bijamrita + Jiwamrita (5%, 10%, 10%, and 10%, respectively at time of sowing, 21, 42 & 63 DAS) + Ghanajiwamrita (250 kg/ha) + Mulching (10 t/ha), T4 − Farm yard manure (10 t/ha), T5 − Farm yard manure (10 t/ha) + Ghanajiwamrita (250 kg/ha), T6 − Biofertilizers (Rhizobium + PSB) + Farm yard manure (10 t/ha) + Vermiwash at 15, 30 & 45 DAS (1:10), T7 − Biofertilizers (Rhizobium + PSB) + Vermicompost (7.5 t/ha) + Vermiwash at 15, 30 & 45 DAS (1:10), T8 − Absolute control]. Experimental site was silty clay loam in texture and acidic in reaction. Available nitrogen, phosphorus and potassium content were medium. The highest values of plant height, dry matter accumulation, unit area efficiency, absolute growth rate, yield attributes, seed yield, gross and net returns were recorded in T7 (Biofertilizers + Vermicompost + Vermiwash) whereas the highest benefit cost ratio was recorded in T6 (Biofertilizers + Farm yard manure + Vermiwash). The lowest values of the above said parameters were noted in T8 (absolute control) except net returns and benefit cost ratio which were the lowest in T1 (Bijamrita + Jiwamrita + Mulching). T7 (biofertilizers + vermicompost + vermiwash) proved to be the best treatment while T6 (Biofertilizers + FYM + Vermiwash) and T5 (FYM + Ghanajiwamrita) proved to be the second and third best treatment in enhancing productivity and profitability of blackgram, respectively.

    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.
