Abstract:

Studies were conducted during the kharif season of 2009 and 2010 to study the growth of local direct-seeded rice cultivars and weeds as affected by different weed management practices under rainfed conditions of Nagaland. Results showed that the cultivars Kezie and Chongloiman recorded significantly better crop growth and yield attributes with significantly higher grain yields of 27.70 q/ha and 25.01 q/ha during 2009 and 28.27 q/ha and 26.09 q/ha during 2010 respectively. Significantly lower weed population, weed dry weight and weed relative growth rate and higher weed control efficiency were also recorded by the cultivars Kezie and Chongloiman. Among the weed management treatments, hand weeding at 20 and 40 days after sowing was found to record significantly higher weed control efficiency with significantly lower weed population and dry weight resulting in better crop growth and superior yield attributes and ultimately recording the highest grain yield of 34.21 q/ha and 35.71 q/ha during 2009 and 2010 respectively.
