Abstract/ Executive Summary:

A field experiment was conducted at Serudanga of Mithapukur upazila under Rangpur district during 2006-07 to study the agro-economic performance of different maize based cropping patterns. The patterns were T₁=Maize–T.aman, T₂=Maize–Mungbean (relay)–T.aman, T₃=Potato–Maize–T.aman and T₄=Maize–Jute (relay)–T.aman. The highest maize equivalent yield (MEY) 30.67 t/ha was recorded in T3 resulting the highest gross return Tk.306700/ha, gross margin Tk.219445/ha and benefit cost ratio (BCR) 3.51 whereas the lowest MEY 9.3 t/ha and BCR 2.17 were in T₁ and T₄.Although production cost was higher in T₃ compared to other patterns, the (Tk.306700/ha) was the highest in this treatment than other treatment combinations.

Keywords: Maize, cropping pattern Potato Jute Mungbean

Location: Mithapukur upazila under Rangpur

Start Date: 07-12-2006

End Date: 15-07-2007

Program Area: Farming System

Commodity: Maize, Jute, Mungbean, Rice

Objectives:

To observe the agro-economic performance of different maize based cropping patterns along with its soil nutrient balance.

Methodology:

The experiment was conducted in medium highland belong to AEZ 3 at Serudanga, Mithapukur, Rangpur and On-station OFRD, Rangpur during 2006-07. Four different maize based cropping patterns were tested. The treatments were T₁=Maize–T.aman, T₂=Maize–Mungbean (relay)–T.aman, T₃=Potato–Maize–T.aman, T₄=Maize–Jute (relay)–T.aman. The first crop maize (variety BARI hybrid maize-5) and potato (var. Diamant) were planted on 07 December 2006 recommended spacing. Maize was harvested on 13 May 2007. Jute (var. O-9897) was sown as relay crop on Apil 20 (130 DAS of maize) and mungbean (var.BARImung-6) were broadcasted as relay crop on April 05, 2007 (115 DAS of maize). After first plucking within 55-60 days, mungbean biomass was incorporated into the soil. Short duration variety BRRI dhan-33 was selected for T.Aman. 196-36-75-30-3-3-1 kg/ha N-P-K-S-Mg-Zn-B was followed for maize (FRG 2005). One-third of nitrogen and all other fertilizers were applied during final land preparation. Remaining nitrogen was applied in two equal split as top dressing at 8-10 leaf stage and at tasseling stage. Four irrigation were given at 3-5 leaves, 8-10 leaves, tasseling and grain filling stage of maize. For potato recommended dose 300-200-250-120-100-10-10 kg/ha urea, TSP, MP, gypsum, MgSO₄, ZnSO₄, boric acid and 10 t/ha cowdung were applied (TCRC, 2005). Half of urea and MP, and all other fertilizers including cowdung were applied in soil before planting. Remaining urea and MP were applied as side-dressing at 30 DAP followed by earthing up and irrigation. Weeding and plant protection measures were taken as and when necessary.

Achievement/Findings:

Treatment T₃gave the highest potato yield (30.67 t/ha).The highest yield of maize was produced in the T₂ (9.5 t/ha), which is at par with T₁ and T₄. The highest maize equivalent yield (MEY) 30.67 t/ha was recorded in T₃ resulting the highest gross return Tk.306700/ha, gross margin Tk.219445/ha and benefit cost ratio (BCR) 3.51 whereas the lowest MEY 9.3 t/ha and BCR 2.17 was in T₁ and T₄ treatments. Although production cost is higher (Tk.87255/ha) in T₃ compared to other pattern but there was higher (Tk.306700/ha) as compared to other treatments.
