Abstract:
A field investigation was conducted at AICRP on Weed Management farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif (June–September, 2020). The experiment was laid out in split plot design with 3 replications and twenty treatment combinations. Results revealed that, in rice all the growth and yield attributes, grain yield, straw yieldand harvest index were substantially enhanced by drip fertigation with 125% RDNK in 5 splits than lower fertigation levels (75 and 100%) and over conventional soil application with 100% RDF. Drip fertigation at 125% RDNK in 5 splits recorded higher rice grain yield of 5103 kgha-1. The drip fertigation at 125% RDNK in 5 splits registered maximum GMR (₹ 120353 ha-1), NMR (₹ 72924 ha-1) and B:C ratio (2.54).

Among the various weed management practices, farmers’ practice (2 HW at 15‒20 days interval after sowing fb. 2 hoeing) significantly improved the major growth and yield parameters whereas, among the herbicides, directed spray of Pretilachlor+Pyrazosulfuron Ethyl @ 0.615 kg a.i. ha-1 PE fb. Bispyribac sodium @ 0.025 kg a.i. ha-1 at 25 DAS recorded significant reduction in weed density, weed dry matter, highest weed control efficiency and the lowest weed index; which ultimately resulted in maximum rice grain yield (5231 kgha-1). The herbicidal application of Pretilachlor+Pyrazosulfuron Ethyl @ 0.615 kg a.i. ha-1 PE fb. Bispyribac sodium @ 0.025 kg a.i. ha-1 at 25 DAS registered maximum GMR (₹128755 ha-1), NMR (₹81412 ha-1) and B:C ratio (2.72) among all herbicidal treatments, indicating the feasibility of using herbicides for effective weed management in rice.
