Sc. Pramanik et al., IRRIGATION AND NITROGEN EFFECTS ON OIL YIELD AND NITROGEN UPTAKE BY ETHIOPIAN MUSTARD (BRASSICA-CARINATA), Indian Journal of Agronomy, 41(1), 1996, pp. 101-107
An experiment conducted in sandy-loam soil of New Delhi during the win
ter season (rabi) 1989-90 and 1990-91 revealed that oil cotent in seed
of Ethiopian mustard (Brassica carinata A. Braun) increased up to irr
igation water (IW) : cumulative pan evaporation (CPE) ratio of 0.6, bu
t decreased with increasing levels of applied nitrogen. It was inverse
ly related to seed N content. Crop irrigated at an IW : CPE of 0.6 and
fertilized with 100 kg N/ha gave the maximum yield (7.7 q/ha), but hi
ghest quantity of N (92.5 kg/ha) was accumulated in the plants which r
eceived 150 kg N/ha Ethiopian mustard accumulated on an average 45.5 k
g N/ha in plant parts to produce I tonne seeds/ha of which about 73% w
as harvested in seeds.
