Abstract/ Executive Summary:

The experiment was conducted at ARS, Burirhat, Rangpur during rabi season of 2007-08 to Kharif-II, 2008 to find out the productive potential of the improved cropping patterns against farmers pattern and the effect of mungbean residue in T. aman rice in AEZ-3. Six patterns consisting of crops like potato, maize, mungbean and T. aman were tested. The highest potato yield (31.67 t/ha) was recorded in T₄ (incorporation of mungbean into Maize) and it was insignificantly varied from all other treatments except T₁(27.33 t/ha). T₄ treatment produced the highest maize yield (9.46 t/ha) which was significantly higher than all other treatments. The highest mungbean yield (1.47 t/ha) was harvested in T₅which was at par with T₆(1.45 t/ha) but significantly higher than the other treatments. The highest T. aman yield (3.92 t/ha) was found in T₆ which was identical with T₃, T₄ and T₅(3.85-3.90 t/ha). The pattern with mungbean (both up rooted and incorporation into soil) were found to be superior in respect of gross return (Tk.410800-507700 /ha), gross margin (Tk.160800-212700/ha) and BCR (1.63-1.75). Among the patterns having incorporation of mungbean biomass into maize (T₄) was the best performer of its higher profitability.

Location: ARS, Burirhat, Rangpur

Start Date: 00-00-2007

End Date: 00-00-2008

Program Area: Farming System

Commodity: Potato, Maize, Rice, Mungbean

Objectives:

To find out the productive potential of the improved cropping pattern against farmers pattern and the effect of mungbean residue in T. Aman rice .

Methodology:

The experiment was conducted at ARS, Burirhat, Rangpur during rabi season of 2007-08 to Kharif II, 2008 in RCB design with 3 replications. Six treatments of cropping sequence were as follows: 1. FP: Potato-Maize-T. Aman (farmers does) 2. FP: Potato-Maize-T. Aman (recommended fertilizer) 3. AP: Potato-Maize + Mungbean (uprooted). -T.Aman 4. AP: Potato-Maizee + Mungbean (residue incorporated)-T.Aman 5. AP: Potato-Mungbean (uprooted)-T.Aman 6. AP: Potato- Mungbean (residue incorporated). -T.Aman Unit plot size was 3.6m x 4.5m. Farmers’ fertilizer dose was used in T1 while recommended fertilizer dose were used in other treatments. Farmers’ dose was NPKSZnB 100, 25, 50, 6, 0.5, 0.5 kg/ha for potato, 136, 30, 60, 7, 0.5, 0.5 for maize and 38, 5, 15, 4, 0, 0 kg/ha for T. aman. Recommended fertilizer dose was NPKSMgZnB 96, 16, 64, 10, 6, 2.5, 1 kg/ha for potato, 196, 36, 75, 10, 3, 3, 1 kg/ha for maize and 66, 4, 22, 8, 0, 1, 0 kg/ha for T. aman. In T. Aman except N, all fertilizers were applied as basal, N top dressed were at 15, 30, 45 days after transplanting (DAT); in potato ½ N & all other fertilizers as basal and rest ½ N as top dressed at 30 days after emergence (DAE); and in maize except N, all fertilizers as basal. N top dressed at 25 and 45 days after sowing (DAS). Yield and yield contributing characters, biomass yield of mungbean were recrded and analyzed statisticall. Cost and return were computed based on farmgate price of the products.

Total Budget (Tk.) : 20,000/-

Achievement/Findings:

The pattern with mungbean (both up rooted and incorporation into soil) were found to be superior in respect of gross return ( Tk, 410800-507700/ha), gross margin (Tk. 160800-212700 /ha) and BCR (1.63-1.75). Among the tested patterns, Potato-Maizee + Mungbean (residue incorporated)-T.Aman were found agro-economicall profitable compared to other tested pattens.
