Abstract
A study was undertaken at Farming System Research and Development (FSRD) site, Kadamshahar, Godagari, Rajshahi during 2011-2012 to evaluate the influence of different fertilizer doses on mustard yield. The treatments were soil test based (STB) fertilizer dose for high yield goal, STB + 25% more N of STB, STB + 25% NP of STB, STB + 25% NK of STB, STB + 25% PK of STB, STB + 25% NPK of STB, 75% of STB and control. The yield and yield components of mustard were significantly influenced by different doses of fertilizer. The highest number of siliqua plant-1 (109.5), seeds siliqua-1 (32.35) and thousand seed weight (3.12 g) were obtained from treatment STB + 25% NPK of STB. The application of higher doses of fertilizer increased the seed yield of mustard. The highest seed yield (1.59 t ha-1) was obtained from treatment STB + 25% NPK of STB showing an increase of 194.44% yield over control. The lowest seed yield (1.21 t ha-1 ) was recorded in control treatment. The highest marginal value product (MVP) of Tk. 57750 ha-1 was obtained from STB + 25% NPK of STB treatment. The highest marginal benefit cost ratio (MBCR) over control (5.37) was also obtained from STB +25% NPK of STB treatment. So, STB + 25% NPK of STB i. e. the fertilizer dose N101P25K56S11Zn1.5B0.5 kg ha-1 as optimum and economically profitable for mustard production in High Barind Tract soil.
