Integrated weed management in upland rice intercropped in coconut

- Ravikiran, Elizabeth K. Syriac, Sheeja K. Raj


A field study was conducted during Kharif 2017 at Coconut Research Station, Balaramapuram, to standardize an economic weed management strategy for upland rice intercropped in coconut. The study revealed that stale seedbed method recorded significantly lower total weed population, total weed dry weight and higher weed control efficiency, grain yield (2.90 t ha-1), net income (A 27,848/-) and B: C ratio (1.48) compared to no stale seedbed method (conventional). Among the weed management methods, penoxsulam @ 20, 25 and 30 g ha-1 followed by (fb) either hand weeding (HW) or metsulfuron methyl +chlorimuron ethyl effectively controlled weeds and recorded lower total weed dry weight and higher weed control efficiency at 60 DAS. Penoxsulam @ 25 g ha-1 at 10-15 DAS fb HW at 35-40 DAS registered the highest grain yield (3.23 t ha-1), net income (A 36,090/-) and B: C ratio (1.63). Integration of stale seedbed method with the broad-spectrum herbicide penoxsulam @ 25 g ha-1 at 10-15 DAS fb HW at 35-40 DAS can be recommended as an effective weed management practice in upland rice.
