Influence of irrigation and nitrogen on growth, seed and oil yield of Ethiopian mustard (Brassica carinata)
Year: 2001
Type: article
Abstract: The field experiment wns conducted at Indian Agricultud Research Institute, New Delhi, during winter season (robi) of 1989-90 and 1990-91 in a sandy-loam alluvial soil on Ethiopian mustard (Brassica corinnto A. Braun) with 4 levels each of imgation water : cumulative pan evaporation ratio (unirrigated control and irrigation at IW : CPE ratios of 0.4.0.6 and 0.8) and nitrogen (0, 50, 100 and 150 kgha). The growth and yield attributes, seed and oil ylelds increased significantly only up to an IW : CPE ratio of 0.6 (2 irrigations). Nitrogen application improved the growth and yield attributes, and also the seed and oil yields significantly up to 100 kg Nlha, but harvested biomass up to 150 kg Nlha. Imgation and N interacted sig- nificantly for plant height, total branches and siliquaelplant, harvested biological and seed yield. Signifi- cantly higher seed production (19.8 qha) and oil yield (7.7 qha) were obtained from the crop irrigated at an IW : CPE ratio of 0.6 fedlizd with 100 kg Nha, but biomass yield (83.3 qha) was highest with 150 kg NI ha at an IW ; CPE ratio of 0.8.
