International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Methodology The field experiment on rRabi sorghum (cultivar M 35-1) under dryland conditions was laid out conducted at AICRP for Dryland Agriculture Research Station, Mulegaon Farm, Solapur during 2005-06 to 2016-17 for twelve years. The experiment was laid out in split plot design containing nine treatment combinations replicated three times includes three main plot treatments viz: 1) Low tillage (LT) - sowing with seed drill and light harrowing after sowing – (SSLH) 2) Medium tillage (MT) - one harrowing + SSLH+ one hoeing 3) Conventional tillage (CT) - plough once in 3 year + one harrowing + ridges and furrows + one harrowing + SSDH + three hoeings and three sub-treatments viz: 1) Organics - 50 kg Nha -1 (50 % CR+50 % LL) CR–Crop residue, LL–Leucaena loppings - N1 2) Organics + chemical fertilizers - 25 kg N ha -1 through urea + 25 kg N ha -1 through organics (50 % CR + 50 % LL) - N2 3) Fertilizers (RDF) : 50 kg N + 25 Kg P2O5 ha -1 - N3. The average nitrogen content of crop residue and leucaena during 12 years are 0.48 % and 3.04 % respectively. The N, P and K were applied through urea, single super phosphate and muriate of potash respectively. The data on crop yield, total N uptake, economics, moisture use efficiency (MUE) of grain were recorded at harvest of sorghum. After harvest of crop, soil samples were collected (0-15 cm) and analyzed for organic carbon (wet oxidation method), available N (0.32 % alkaline KMnO4oxidizable), available P (0.5 M NaHCO3 extractable, pH 8.5,) and K (Neutral normal ammonium acetate extractable) following the procedures described by Page et al. (1982). The input energy (MJ ha −1 ) and output energy was/ were computed for each treatment and expressed in terms of MJ ha −1 as suggested by Mittal et al. (1985). The energy use efficiency (EUE) derived as a ratio of output and input energy for each treatment (Sankar et al., 2013). Results In the tillage and nutrient management practices, the maximum input energy was observed in CTN1 (63924 MJ ha -1 ) whereas the minimum input energy was observed in treatment LTN3 (4391MJ ha -1 ) followed by treatment MTN3 (4945 MJ ha -1 ). The maximum output energy was observed in MTN2 (70389 MJ ha -1 ) followed by CTN2 (68308 MJ ha -1 ). The maximum energy use efficiency was observed in LTN3 (13.865) followed by MTN3 (13.323). In case of nutrient management, the maximum energy use efficiency was observed in N 3 (11.919) followed by N 2 (1.966). Also, it is observed that, minimum energy of 48.22 MJ was required for production of one kg grain where nutrition of 50% organic and 50% inorganic N recorded highest 625 | Page Resource conservation and rainfed agriculture
International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad grain (17.06 qha -1 ) and stover yield (40.84 qha -1 ) also (Table 1) as seen in the findings of Maruti Shankar et al. (2013 The conventional tillage recorded significantly higher grain (16.62 q ha -1 ) and stover yield (40.46 q ha -1 ). However, it was on par with medium tillage (16.06 and 39.64 q ha -1 respectively). The moisture use efficiency (MUE) was maximum in conventional tillage (7.42 kg ha -1 mm -1 ). (Table). The N application 50 % through organic + 50 % through chemical fertilizer (N 2) recorded higher MUE (7.79 kg ha -1 mm -1 ). Conclusion One harrowing + sowing with seed drill and light harrowing + one hoeing at 3 rd week and 25 kg N through inorganic fertilizer (Urea) and 25 kg N through organic manure (12.5 kg N through crop residue (byre waste) + 12.5 kg N through Leucaena lopping or any green loppings) + 12.5 kg P 2O 5 through fertilizer (SSP) is recommended for rRabi sorghum grown on medium deep black soils in scarcity zone of Maharashtra for getting higher grain and stover yield and monetary returns with saving of energy use and maintaining soil fertility.
