Abstract
An experiment on chickpea was conducted at Farming System Research and Development (FSRD) site, Kadamshahar, Godagari, Rajshahi (AEZ 26) during 2011-2012. The objective was to find out the suitable and economic fertilizer dose for maximizing the yield. The soil of the experimental field was chemically analyzed and levels of the fertilizers were calculated on the basis of target yields as per Fertilizer Recommendation Guide’ 2005 published by the Bangladesh Agricultural Research Council. The treatments were T1: Soil test based (STB) fertilizer dose for high yield goal (FRG, 2005), T2: T1 + 25% N, T3: T1 + 25% NP, T4: T1 + 25% NK, T5: T1 + 25% PK, T6: T1 + 25% NPK, T7: 75% of T1 and T8: control. The maximum number of pods plant-1 (86.41) was obtained from treatment T6 followed by treatment T5 (80.01) and the minimum (59.08) was in treatment T8. The maximum number of seeds pod-1 (1.67) and hundred seed weight (11.73 g) was obtained from treatment T6. The maximum seed yield (1.69 t ha-1) was obtained from treatment T6 showing an increase of 79.57% over control and was significantly different from all other treatments. The next maximum seed yield (1.45 t ha-1) was observed in treatment T5 which was at per with treatment T2, T3 and T4 and minimum yield (0.95 t ha-1) in control plot (T8). The highest marginal value product (MVP) of Tk. 44400 ha-1 was obtained from T6 treatment followed by Tk. 30600 in T5 treatment. The highest MBCR over control (6.01) was obtained from T6 treatment. So, the fertilizer dose N25P33K34S16Zn1.5B0.75 kg ha-1 was optimum for maximizing the yield as well as economically profitable and viable for chickpea production in High Barind Tract soil.
