International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad before the sowing of maize and wheat as per the treatments. The sources of N, P and K were urea, single superphosphate and diammonium phosphate and muriate of potash. Maize (PMH 13) and wheat (PBW 660) were grown in monsoon (July to September) and winter season (November to April), respectively. One half of N was applied at the time of sowing and remaining half at knee high stage in maize and crown root initiation stage in wheat. Other recommended cultural practices for both the crops were followed throughout the study. Results The yield of maize increased with nutrient management treatments as compared to control. Significantly higher grain yield of maize (3711 kg ha˗1 ) was recorded with 100% NPK + FYM 10 t ha˗1 as compared to control, N (100% RDF) and NP (100% RDF) but was statistically at par with all other treatments. The higher water use efficiency (6.25 kg ha˗1 mm˗1 ) was also recorded in the treatment 100% NPK + FYM 10 t ha˗1 as compared to other treatments. In wheat, significantly higher grain yield was recorded with 100% NPK + FYM 10 t ha˗1 as compared to control, N (100% RDF), 100%N through FYM and 100%N through FYM+ biofertilizers but was statistically at par with all other treatments. The highest water use efficiency was also recorded in the treatment 100% NPK + FYM 10 t ha. Soil moisture exhibited significant variation among the treatments. The FYM substituted plots, by and large, had significantly higher soil moisture than sole chemical fertilized and control treatments. Organic carbon exhibited significant variation among different treatments and highest OC was recorded in NPK (100%RDF) + FYM10 t ha˗1 as compared to all other treatments.
