EFFECT OF VARIETY AND FERTILIZER ON THE GROWTH AND YIELD OF MUSTARD (Brussica campestris)

Abstract

A field experiment was conducted during the Rabi season 2007-08 to find out the optimum and economically viable fertilizer dose of mustard varieties: I3ARI sharisa-9, HART sharisa-12 and BARI sharisa-15. A total of 5 treatments including one control comprising different dose of' chemical fertilizers were used in the studs. The treatments were F 1 (N11 +P;c I S25 -Z ( N 91 FP30± I(40+ S2(1+Z111+ B1 N30+P,0 ± K,0- S 1(j +7.n1 I 5 ). F (NId) IP2 -i- K30+ S 15+Zn2-I B1 () ) and F5 (Native nutrient). The data revealed that the variety BARI sharisa-15 gave higher no of seeds per siliqua. 1000 seed weight and took highest days to 50% flowering and maturity than other variety. On the oilier hand maximum number of' primaiy branches, siliqun length. harvest index and oil eontenl were given by BARI sharisa-l2 .Another variety BARI sharisa-9 gave highest number of siliquae per plant. seed yield and harvest index. The highest seed yield and stayer yield was found with higher dose of fertilizer in treatment F1 (N10—P+ K c( i Zn.1 + 132). Flic oil content was found to he increased with decreasing fertilizer dose. The highest yield (1773 kg/ha) and number of' siliqtia per plant were recorded in BARI sharisa-9 with the highest dose of chemical fertilizer (F 1 ). But the highest number of primary branches per plant. number of seeds per siliqua. 1000 seed weight and stover yield were given by the variety BARI sharisa-15 with F 1 lertilizer.
