Response of inorganic fertilizers biochar wheat residue and farm yard manure on soil properties and yield of paddy (Oryza sativa L.) var. PB1121

An experiment was conducted on “Response of inorganic fertilizers biochar wheat residue and farm yard manure on soil properties yield of Paddy (Oryza sativa L.) var. PB1121” in kharif season, 2024 at the Crop Research Farm of Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was laid out in a randomized block design (RBD) with 3 replications consisting of 9 treatment combinations. The treatment of biochar includes 3 level (@ 0 t ha-1, @ 2.5 t ha-1, @ 5 t ha-1), the treatment of wheat residue includes @ 0 t ha-1, @ 2.5 t ha-1, @ 5t ha-1 ), and the treatment of FYM includes (@ 0 t ha-1 , @6.25 t ha-1 , @ 12.5 t ha-1 ). The results experiment depicts that application of FYM @ 12.5-ton ha-1 significantly improves the physio-chemical properties of soil the maximum pore space 47.55%, water holding capacity 44.66%, electrical conductivity dS m-1 0.26, maximum organic carbon 0.56%, available nitrogen 291.76 kg ha-1, available phosphorus 24.87 kg ha-1 , available potassium 235.86 kg ha-1 was recorded in treatment T9 - [RDF@ 100% +FYM @ 100%]. Similarly, the maximum, plant height 126.67, No. of panicle 26.00, grain yield 43.47q ha-1, straw yield 63.88 q ha-1, test weight 29.73 g, cost benefit ratio (C : B) 1:2.05 were recorded in T9 [RDF @ 100% + FYM @ 100%].
