Development of Fertilizer Recommendation for Lentil+mustard-b.aus-black Gram Cropping Pattern in Charland Under Aez-11

Chief Scientific Officer & Head, OFRD and Relevant Scientists of OFRD, BARI

Abstract/ Executive Summary:

To determine the appropriate fertilizer dose for enhancing production and income from Lentil+Mustard-B.Aus-Black gram cropping pattern an experiment was conducted at the charland of Charsadipur village of Pabna during Rabi season of 2013-14. Eight fertilizer treatments, viz: T₁= 100% N-P-K-S-Zn (soil test based), T₂= 100% N-P-K-S-Zn (STB) + 25% N, T₃= 100% N-P-K-S-Zn (STB) + 25% NP, T₄= 100% N-P-K-S-Zn (STB) + 25% NK, T₅= 100% N-P-K-S-Zn (STB) + 25% PK, T₆= 100% N-P-K-S-Zn (STB) + 25% NPK, T₇= 75% N-P-K-S-Zn (STB) and T₈= Control; were tested on the cited pattern. The variety BARI Masur-6, BARI Sarisha-14, BARI Mash-3 and Hashikalmi of lentil, mustard, black gram and B.Aus rice, respectively were selected for this study. The experiment was laid out in RCB design with three replications. Soil test based 100% N-P-K-S-Zn (STB) + 25% NPK (T₆) demonstrated better performance on crop growth and yield of crops in the lentil+mustard-B.Aus-Black gram cropping pattern in the charland ecosystem of Pabna. The maximum economic return in terms of gross return and gross margin was also recorded in the same fertilizer package T₆.

Commodity: Fertilizer

Objectives:

To verify the fertilizer recommendation for lentil+ mustard crops in Lentil+Mustard-B.Aus-Black gram cropping pattern in the char land

Methodology:

The experiment was conducted at charland of Charsadipur areas of Pabna during Rabi season of 2013-14. The experiment consisted of eight fertilizer treatment packages viz. T₁= 100% N-P-K-S-Zn (soil test based), T₂= 100% N-P-K-S-Zn (STB) + 25% N, T₃= 100% N-P-K-S-Zn (STB) + 25% NP, T₄= 100% N-P-K-S-Zn (STB) + 25% NK, T₅= 100% N-P-K-S-Zn (STB) + 25% PK, T₆= 100% N-P-K-S-Zn (STB) + 25% NPK, T₇= 75% N-P-K-S-Zn (STB) and T₈= Control. The variety BARI Masur-6 and BARI Sarisha-14 was used in this study. After completion of land preparation the entire amount of all fertilizers were applied as per treatment specification. The seeds of lentil and mustard were broadcasted in each plot on November 10, 2013 maintaining the same ratio of 80:20 for lentil+ mustard. Three times weeding were done at vegetative stage for better growth of the crops. Stem phylum disease of lentil Rovral 50 WP @ 2.5 g L^-1 was applied 3 times at 7-10 days interval. Other intercultural operations were done when required. Lentil and mustard was harvested on February 23 and February 9, 2014, respectively. Necessary data on days to flowering, days to maturity, yield and yield contributing characters were collected and analyzed through statistical analytical package.

Achievement/Findings:

Fertilizer package with soil test based 100% N-P-K-S-Zn (STB) + 25% NPK (T₆) showed best performance on crop growth and yield in Lentil+Mustard-B.Aus-Black gram cropping pattern in the charland of Pabna. The maximum economic return in terms of gross return and gross margin was also recorded from the same treatment.
