Abstract

The study was conducted during the Kharif season in 2022 at the research field of the School of Agriculture, Department of Agronomy, Lovely Professional University in Phagwara, Punjab. The objective of the study was to determine the “Effect of different organic sources of nutrients on growth and yield of rice (Oryza sativa L.) under the SRI method”. The experiment was set up using a randomized block design with twelve treatments and each replicated three times. The treatments included various combinations of different organic sources of nutrients viz., T1 (100 % RDN from farmyard manure), T2 (100 % RDN from vermicompost), T3 (100 % RDN from poultry manure), T4 (100% RDN from groundnut oilcake), T5 (100% RDN from mustard oilcake), T6 (50 % RDN from farmyard manure + 50 % RDN from vermicompost), T7(50 % RDN from farmyard manure + 50 %RDN from poultry manure), T8 ( 50% RDN from farmyard manure + 50 % RDN from groundnut oilcake), T9 (50 % RDN from farmyard manure + 50 % RDN from mustard oilcake), T10 (50 % RDN from vermicompost+ 50 % RDN from poultry manure), T11 (50 % RDN from vermicompost + 50 % RDN from groundnut oilcake) and T12 (Control). Among the twelve treatments, T4 (100% RDN from groundnut oilcake) showed the most significant impact on the growth and yield. This treatment led to higher growth parameters, such as plant height (98.80 cm), number of tillers hill-1 (18.13), dry weight (66.40.g), root and shoot ratios (0.12), yield parameters like test weight (22.87g), effective tillers hill-1 (17.67), grain yield ha-1 (6.09 t), straw yield ha-1 (9.85 t) and harvest index (38.53%).
