Abstract:

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. The next best was three times cono weeding was economically feasible in both the seasons. Adopting 15 days old seedlings with four times cono weeding followed by 15 days old seedlings with three times cono weeding registered higher yield and yield attributes in rice, besides it also gave higher net return by reducing the cost production particularly in edging out higher inorganic fertilizers and weeding through cono weeding without affecting the grain yield in rice was proved by the study.
