Study the effect of different nitrogen levels on growth and yield of mustard crop at Ambikapur (Chhattisgarh)

Abstract

The field experiment entitled “Effect of Different Rates of Nitrogen and Sulphur on Growth and Yield of Indian Mustard (Brassica juncea L.) Under Northern Hill Zone of Chhattisgarh.” was conducted at Instructional-cum-Research Farm, Rajmohini Devi College of Agriculture & Research Station, Ambikapur (C.G.).During rabi 2019-20. The study was conducted in factorial randomized block design in three replications with four doses of nitrogen (30, 60, 90 and 120 kg/ha). Application of nitrogen significantly increased Growth parameters like plant population, plant height, number of leaves/ plant, number of branches/ plant. Nitrogen application significantly increased Yield attributing characters like siliquae per plant, seeds per siliqua.The maximum number of siliiqua/plant, length of siliiqua, seeds/ siliiqua, test weight, oil content (%), oil yield (kg /ha.) were found in dose of 120kg N+ 40Kg S/ha. The minimum number of number of siliiqua/plant, length of siliiqua, seeds/ siliiqua, test weight, oil content (%), oil yield (kg /ha.) were observed in dose of 30kg N/ha. The maximum seed yield were found in dose of 120kg N/ha. And minimum seed yield were observed in dose of 30kg N/ha. Effect of nitrogen (120 kg N / ha) was observed higher in net return. Single dose of nitrogen 120 kg S/ha. Suggested of Indian mustard (Brassica jancea L.) under the northern hill zone of Chhattisgarh.
