Abstract: A field experiment was conducted during rabi season of 2014-15 at the Agriculture Farm of MGCGVV Chitrakoot, Satna (M.P.) to optimize the doses of basal and foliar feritization The 12 treatments comprising 03 basal (50, 75, and 100%N) and 03 foliar application of N with supplying chemicals like KNO3, Urea and Ca (NO3)2a and their combination along with 100% NPK and a control were tested in 3 replication in randomized block design. Growth parameters plant height (c.m),leaves/plant, dry matter/plant (g),root length (cm),spread(cm), dry weight(g),yield attributes No. of siliqua per plant No. of seeds per siliqua Seed weight/plant (g) Seed yield (kg/ha) Stover yield (kg/ha) Harvest index (%) and seed yield and stover yield were significantly uncreased with 75% basal N+2sprays of 1%KNO3 or 2% urea. However gowther parameaters, yieldattibutis and grain and strower yield were found significantly higher under 100% NPK+2%ws but these value were registered significantly at par with 75%basal N+2 spray of !%KNO3 or urea. Net returns and benifical cost ratio was also significantly higher under basal application of 75%N basal + 2%urea, 75% Nbasal +1% KNO3 +75% N basal+1% Ca(NO3)2. The fertility level at 75 % of recommended dose of fertilizers as basal application with two foliar sprays of T10:75% basal N +2 spray of 2% urea or 1% KNO3 at 30 and 45 days after sowing was the best treatment combination with regard to the seed yield and net returns in mustard underrainfed condition.
