Abstract/ Executive Summary:

A field experiment was carried out at Multi Location Testing (MLT) site, Debiddar and Chandpur during Rabi season of 2015-16 to find out the suitable boro rice planting method with cost and return of inter mixed cropping system in Cumilla region. The treatment combinations used were T₁ : Boro rice (broadcast) + Mustard, T₂ : Boro rice (Line sowing) + Mustard, T₃ : Sole Mustard, T₄ : Sole boro rice. Results revealed that all the mixed cropping combinations showed superior in terms of gross return, gross margin and rice equivalent yield (REY) than sole cropping. The highest rice equivalent yield (8.52 t ha^-1) was found in the treatment combination of boro rice line sowing + mustard. From the cost and return analysis it was observed that the combination of boro rice line sowing with mustard (T₂) gave the highest gross return (Tk. 127800 ha^-1) and gross margin (Tk. 77400 ha^-1) where sole crop of mustard (T₃) gave the lowest gross return (Tk. 65120 ha^-1) and gross margin (Tk. 21450 ha^-1) which indicated the advantage of mixed cropping over the sole

Objectives:

To find out the suitable rice planting method in mustard boro mixed cropping system with cost and return in Cumilla region.

Methodology:

The experiment was carried out at MLT site, Debiddar and Chandpur during Rabi season of 2015-16 to find out the suitable rice planting method in Mustard- Boro inter mixed cropping system with cost and return in Cumilla region. The soils of the experimental areas belong to the AEZs 19, 22 and 30 (FRG, 2012). The soils of the experimental plots were clay loam in texture. The experiment was laid out in Randomized Complete Block design with five dispersed replications. It was consisted with four treatments as follows: T₁ : Boro rice (broadcast) + Mustard, T₂ : Boro rice (Line sowing) + Mustard, T₃ : Sole Mustard, T₄ : Sole boro rice. According to the treatments, seeds of mustard (var. BARI Sarisha-14) and boro rice (var. BRRI dhan58) were broadcasted and line sown on 09-11 November 2015 @ 8 and 40 kg ha^-1, respectively. The unit plot size was 100 m². The lands were fertilized with 18.43, 16, 20, 7, 1.43 and 1.36 kg N-P-K-S-Zn and B ha^-1, respectively. 2/3 urea and total amount of other fertilizers were applied during final land preparation as basal and rest 1/3^rd urea was applied as top dress at 30 days after broadcasting (BARI, 2014). Plant protection measure and all other management practices were done for mustard and boro rice as and when necessary. Mustard was harvested on 04-06 February 2016, where as boro rice on 24-26 April, 2016. Data on the different crop parameters were collected from the 10 randomly selected sample plants and then average was taken which was further analyzed by software program Statistix 10. Rice equivalent yield (REY) and economic analysis were calculated to ascertain the efficiency of intercropping. Rice equivalent yield was calculated by converting yield of mixed crops to the yield of rice on the basis of prevailing market prices of individual crops.

Achievement/Findings:

Considering the yield and economic return it can be concluded that boro rice in line sowing with mustard is the most profitable when grown as mixed crop and risk of cultivation of mono crop can be reduced by mixed cropping.
