Abstract/ Executive Summary:

An experiment was conducted to find out a suitable banana (Ranginsagar and Sabari) based intercrop combination of potato and mustard in the research field of Institute of Biological Science of Rajshahi University, Rajshahi-6205, during Rabi season of 2003-2004. Average over the two years, it revealed that the highest yield of banana was observed in Ranginsagar + potato (64.72 t ha^-1) and the lowest in sole mustard (1.92 t ha^-1). Combinations of Ranginsagar + potato intercropping showed better performance than other combination and sole crop in respect of gross return (Tk. 735219 ha^-1), net return (Tk. 359794 ha^-1) and benefit cost ratio (1.95). The highest land equivalent ratio (LER) was 1.82 in Ranginsagar + Potato followed by Sabari + potato (1.79) and the lowest in Sabari + mustard (1.60). The economic return was more in intercropping than all sole crops.

End Date: 00-00-2004

Program Area: Farming System

Commodity: Banana, Potato, Mustard

Objectives:

The present study was under taken to find out yield, cost and net return of the intercropping system in order to select the best banana based one.

Methodology:

The experiment was conducted at the research field of Institute of Biological Sciences of Rajshahi University, Rajshahi-6205 in the North-west region of Bangladesh during the period of Rabi season of 2003-2004 in Randomized Complete Block Design with three dispersed replications for selecting responds. The unit plot size was 6x4 m. Banana spacing (plant to plant 2x2 m apart) was maintained to accommodate potato and mustard per unit plot. Two genotypes of banana, namely Ranginsagar (AAA; 3n = 33) and Sabari (AAB, 3n = 33) were collected from the farmers field and potato and mustard seeds were from BADC form Nowdapara. Totally eight different treatments were taken in the study, such as sole Ranginsagar, sole Sabari, sole potato, sole mustard, Ranginsagar + potato, Ranginsagar + mustard, Sabari + potato and Sabari + mustard. The land of the experimental site was medium high and the soil was silty loam with pH 6.0 to 7.0, 45 to 50 days old banana seedlings were transplanted into the respective pits on first weeks of November in both the year. The seeds of potato and mustard were planted as sole and intercrop between the two rows after planting the banana in both the year. The land was prepared to fine tilth and fertilizers were applied as per recommendation. All the fertilizers except urea were applied during the final land preparation in sole banana but in sole potato, mustard as well as in intercropping combinations 40% urea and MP, entire quantity of TSP, gypsum and Zn were broadcast at the time of final land preparation and the remaining urea and MP were applied into equal splits at 35 days and 55 days after transplanting. Necessary intercultural operations were done to facilitate the growth and development of the crop. Marketable potato, mustard and banana were harvested at 100-110, 90-100, 300-310 (Ranginsagar) 375-380 (Sabari) days, respectively after transplanting. Collected data were analyzed by following standard statistical methods (Equivalent yield, LER and BCR etc.) and significant text was computed from F test and LSD (0.05) technique. Banana equivalent yield was calculated by converting yield of intercrops to the yield of banana on the basis of prevailing market prices of the individual crops. The formula is as follows:

Where:

Y₀	=	Yield of banana
Y_i	=	Yield of intercrop (potato/mustard)
P_i	=	Selling price of intercrop (potato/mustard)
P₀	=	Selling price of banana

Benefit Cost Ratio (BCR) = Gross return/Cost of cultivation

Achievement/Findings:

All the intercrop combinations performed better yield than those of sole crop but the individual yield of banana was decreased in intercrop combinations. The economic return was more in intercropping than all sole crops.
