TAILIEUCHUNG - Effect of age of seedlings, weed management methods on yield attributes and economics under system of rice intensifications (SRI)

System of Rice Intensification (SRI) with weed management is an imperative to convince the today’s crop production in a sustainable way. Due to scarcity of water and energy, the weed competition is going to be the major constraint in achieving higher production in transplanted rice. In order to standardize the age of seedlings and to evaluate alternate practices to cono weeding, two field experiments were conducted during Rabi 2010-11 and Kharif 2011 at Perunthalaivar Kamaraj Krishi Vigyan Kendra (PKKVK), Puducherry State experimental farm in a factorial randomized block design with three replication. The treatments were formed by combination of two ages of seedlings and five weed management practices that were tested on System of Rice Intensification crop. The findings of two seasons, use of 15 days old seedlings with four times cono weeding was performed excellent by registering higher yield attributes and grain yield of 5360 and 4020 kg ha-1 during Rabi 2010-11 and Kharif 2011 respectively. | Effect of age of seedlings, weed management methods on yield attributes and economics under system of rice intensifications (SRI)
