Effect of phosphorus enriched compost on growth, yield attributes and yield of kharif rice

A field experiment was conducted at the College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the kharif season of the years 2021 and 2022 to assess the “Effect of phosphorus enriched compost on growth, yield attributes and yield of kharif rice”. The field treatments was laid out in randomized block design including T1: RDP + Compost, T2: 20 days conditioned compost, T3: 20 days conditioned 400% RDP compost, T4: 20 days conditioned 600% RDP compost, T5: 40 days conditioned compost, T6: 40 days conditioned 400% RDP compost, T7: 40 days conditioned 600% RDP compost, T8: 60 days conditioned compost, T9: 60 days conditioned 400% RDP compost and T10: 60 days conditioned 600% RDP compost. The experiment was conducted for two consecutive years in different location. Result of field experiment showed that the growth parameter of kharif rice namely plant height and yield parameter test weight found non-significant with different treatments of phosphorus-enriched compost in both year as well as in pooled analysis. The significant effect of treatment T10 (60 days conditioned 600% RDP compost) were found in case of no. of tillers/hill and panicle length in both year and pooled analysis as well. Significantly the higher grain and straw yield of kharif rice were observed with treatment T10 in both year and pooled analysis.
