SUSTAINABLE PRODUCTION OF SCENTED RICE (ORYZA SATIVA) WITH MANURES AND BIOFERTILIZERS

Abstract

A field experiment was conducted at Kalai (Aligarh) research station of C.S. Azad University of Agriculture and Technology, Kanpur during rainy (kharif) season in randomized block design with four replications consisted of FYM (0.6%N, 0.2%P,and 0.5%K), vermicompost (1.4%N, 1.1%P, and 0.6%K), green manure (Sesbania esculata), Azospirillum, phosphate solubilizing bacteria(PSB), and blue green algae (BGA) having nine treatments viz. T1, NPK@ 90 : 40 : 40 : kg/ha; T2,FYM @ 10 t/ha + Azospirillum (Azos) + PSB + BGA; T3, vermicompost (VC) @ 5t/ha Azos + PSB + BGA ; T4, GM + BF (A + P + B); T5, GM + FYM(5 t/ha) + BF (A + P + B); T6, GM+VC (2.5t/ha) + Azos + PSB + BGA; T7, GM + FYM (10t/ha) + Azos + PSB; T8, GM + VC (5t/ha) + Azos+PSB,and T9, Absolute control (N, o Po Ko). The study revealed that among the variouscombinations of green manure, FYM or vermicompost and biofertilizers tested, green manure along with FYM (5 t/ha) or vermicompost (2.5 t/ha) in conjunction with biofertilizers (Azos + PSB + BGA) proved better manurial schedule for yield maximization in scented rice. The results clearly indicated that scented rice may efficiently and profitable be cultivated without using chemical fertilizers withthe additional advantage of quality grain besides improvement in soil health as well as balance inagro-ecosystem.
