Growth, Yield Attributes and Yield of Rice as Influenced by Paddy Residue and Nitrogen Management Options under rice-rice Cropping Systems

Abstract

A field experiment was conducted to know the impact of paddy residue and nitrogen management options on “Growth, yield attributes and yield of rice as influenced by paddy residue and nitrogen management options under rice-rice cropping systems during 2021-22 and 2022-23 at Regional Agricultural Research Station, Arepally, Warangal district. It is situated in the Central Telangana Zone. The experiment was laid out in factorial RBD design with 18 treatments replicated thrice. The results of the experiment revealed that grain yield, straw yield was significantly affected by both paddy straw and nitrogen management options highest was found in incorporation of crop residue along with 130% Recommended dosage of Nitrogen (RDN).  Growth and Yield attributes like plant height, number of tillers per hill, panicle length, Productive tillers per hill, Number of grains per panicle, 1000 seed weight (gms) was also obtained highest in incorporation along with 130% RDN. Results of the experiment conclude that highest growth, yield and yield attributes was obtained highest in incorporation along with 130% RDN.
