Abstract/ Executive Summary:

On-Farm experimental trial were conducted on the field of Multi Location Testing (MLT) site at Amtali, Borguna and Farming System Research & Development (FSRD) site Razakhali, Dumki, Patuakhali during the Rabi season of 2014-2015.The experiment was laid out in RCB design with six treatments i.e. T₁: Chickpea 100%, T₂: 100% Mustard, T3:100% chickpea + 15% Mustard, T₄: 100% chickpea + 20% Mustard, T₅: 100% chickpea + 25% Mustard, T₆: 100% chickpea + 30% Mustard were used in the trial.In this trial campestris group of mustard & high yielding Chickpea varieties was used. Results revealed that the yield of chickpea decreased with the increase of mustard population in the mixed cropped situation in both the locations. At Razakhali, the highest Chickpea Equivalent yield (1730 kg/ha) was recorded from T₃:100% chickpea + 15% Mustard treatment followed by T₄: 100% chickpea + 20% Mustard (1640 kg/ha). The highest gross margin Tk. 44260 and lowest gross margin Tk. 14270 was also obtained from T₃ and T₁ respectively. At Amtali location the highest Chickpea Equivalent yield (1575 kg/ha) was observed from treatment T₃:100% chickpea + 15% Mustard followed by T₄: 100% Mustard(1480 kg/ha). Accordingly the highest gross margin Tk. 35180 and lowest gross margin Tk. 15070was obtained from T₃ and T₁ respectively. The height BCR 1.74 & 1.59 was also found from T₃ treatment in both the locations respectively. From the result of this on farm trial it is apparent that, mixed cropping is more profitable than the sole cropping and risk of cultivation of one crop can be reduced by mixed cropping.

Location: Amtali, Barguna and FSRD site Rzakhali, Dumki, Patuakhali

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Farming System

Commodity: Chickpea, Mustard

Objectives:

To identify the appropriate ratio of chickpea with Mustard for growing as a mixed crop in the coastal area and to ensure the maximum utilization of the land resource for higher yield and economic return.

Methodology:

An experiment was conducted at MLT site Amtali, Barguna and FSRD site Rzakhali, Dumki, Patuakhali in the rabi season of 2014-2015 to verify the performance of Chickpea and mustard as a mixed crop in the coastal area under farmers field condition. The experimental areas belong to the Low Ganges River Floodplain (AEZ 13). It was consisted with six treatments as follows: T₁: 100% Chickpea @ seed rate 55 Kg ha^-1, T₂: 100% Mustard @ seed rate 7 Kg ha^-1, T₃:100% chickpea + 15% Mustard, T₄: 100% chickpea + 20% Mustard, T₅: 100% chickpea + 25% Mustard, T₆: 100% chickpea + 30% Mustard. The experiment was laid out in RCB design with six dispersed replications having unit plot size 40 m2 (8 m x 5 m). BARI released variety BARI Chola-5 & BARI Sorisa- 14 was used for this experiment. According to the treatments, seeds of Chickpea and Mustard were broadcasted on 11-15 December 2014.The plot was fertilized with 18-16-15-1 kg/ha N-P-K-B. Standard cultural practices (irrigation, mulching, weeding and thinning) and plant protection measure were done as and when necessary. Mustard was harvested on 26-28 February 2015, whereas chickpea on 15-20 April 2015. Data on the different yield and yield contributing parameters were collected from the 06 sample plants and then average was taken which was further analyzed by computer program MSTAT-C. Chickpea Equivalent Yield (CEY) and economic analysis were calculated to ascertain the efficiency of intercropping.

Achievement/Findings:

Considering the yield and return it can be concluded that 100% Chickpea with 15% mustard is the most profitable as compared to other treatment combination when grown as mixed crop in coastal region of Bangladesh. From the result of this experimentation it is evident that, mixed cropping is more profitable than the sole cropping and risk of cultivation of one crop can be reduced by mixed cropping.
