Effect of nitrogen levels on seed yield and quality parameters in Indian mustard genotypes

摘要

Among eight genotypes, RH-9707 produced highest seed yield, oil yield, total protein and stearic acid and lowest erucic acid during 2002-03 and 2003-04 with highest net income of Indian rupees 22123/ha at 80 kg/ha during 2002-03. The significant increase in oil yields due to N was only up to 80 kg/ha. RH-9510 recorded maximum palmitic acid. Palmitic acid stearic acid were not influenced by N levels. Maximum content of oleic, linoleic and eicosenoic acid were recorded in RH-9512, RH9324 and RH-9610 and lowest in RH-9505, RH-9610 and RH-9404, respectively. RH-9505 possessed highest erucic acid. Increasing levels of N resulted in decreased levels of oleic, linoleic acid and eicosenoic acids during the two years study.
