Abstract/ Executive Summary:

An experiment with pure, mixed and intercropping chickpea with mustard at different plant population under rain fed condition was conducted at Joydebpur and Ishurdi in 1990-91 and 1991-92. The highest yield of mustard and chickpea was obtained from sale crops in both the sites. Averaged over the years. two mustard row alternated with 2 chickpea row (50 M : 50 C) appeared to be the best and had higher mustard equivalent yield 11863 kg/ha and 2251 kg/ha). net return (Tk.17263/ha), land equivalent ratio (1.15 and 1.34) and benefit cost ratio (4.39 and 4.17), respectively at Joydebpur and Ishurdi.

Location: Ishurdi, Bangladesh Agricultural Research Institute

Start Date: 00-00-1990

End Date: 00-00-1992

Program Area: Farming System

Commodity: Mustard, Chickpea

Objectives:

To evaluate the performance of high yielding variety mustard and chickpea in pure, mixed and row intercropping situation with various plant population and spatial arrangement under rainfed condition.

Methodology:

The experiments were conducted during rabi seasons of 1990-91 and 1991-92 at Joydebpur and Ishurdi farm of BARI. The experiment consisted of the following treatments: T_I= sole mustard (M), T₂= sole chickpea (C), T₃ = 2 mustard broadcast in between chickpea lines spaced at 90 cm (100M : 33.3C), T₄= 2 mustard rows alternated with 1 chickpea row (66.6 M : 33.3C), T₅= 2 mustard rows alternated with 2 chickpea rows (50M : 50C), T₆ = 3 mustard rows alternated with 1 chickpea row (75M : 25C), T₇ = mustard 100% + chickpea 50% (broadcast.. T₈= mustard 100% + chickpea 25% (Broadcast) and T₉= mustard 75% (broadcast). In both the sites, the experiments were laid out in a Randomized Complete Block Design with four replications. The unit plot size was 5m x 3.6m. The spacing for the sole crops of mustard and chickpea was 30cm x 10cm. The mustard variety Daulat and chickpea variety Nabin were used in .both the locations. Seeds of mustard and chickpea were sown on 8 November 1990 and 5 November 1991, respectively at Joydebpur and on 10 November, 1990 and 12 November 1991, respectively at Ishurdi at the rate of 10 and 40 kg seeds/ha, respectively. The fertilizer dose of 80-60-40=20-5 kg/ha of N, P₂0₅,K₂0,S and Zn was used for sole mustard and mixed/intercropping treatments, while 20-40- 20-20-5kg/ha of N, P₂0₅, S and Zn for sole chickpea. The experiments were carried out under rainfed condition in both the years. At Joydebpur the total rainfall recorded during the crop growth period in 1990-91 and 1991-92 was 72 mm and 128 mm, respectively. Likewise at Ishurdi it was 78.1 mm and 93.3 mm in 1990-91 and 1991-92, respectively. Land equivalent ratio (LER) and Mustard equivalent (kg/ha) were calculated.

Achievement/Findings:

Two mustard row alternated with 2 chickpea row (50 M : 50 C) appeared to be the best and had higher mustard equivalent yield (1863 kg/ha and 2251 kg/ha), net return (Tk.17263/ha), land equivalent ratio (1.15 and 1.34) and benefit cost ratio (4.39 and 4.17), respectively at Joydebpur and Ishurdi.
