Intercropping Groundnut with Mungbean in Varying Plant Population

Dr. Mohammed Amin
Principal Scientific Officer
OFRD, BARI, Noakhali

Abstract/ Executive Summary:

An experiment was carried out at the MLT site, Laxmipur during the rabi season of 2007-08 to verify the performance of mungbean as intercrop with groundnut. Groundnut (100%) with mungbean (40%) produced the highest groundnut equivalent yield (2383 kg/ha) along with the highest LER (1.13). All the int ercropped treatments except groundnut (100%) with mungbean (60 %) showed the highest gross return compared to sole crop of groundnut.

Keywords: Intercropping, groundnut, mungbean,

Location: MLT site, Laxmipur

Start Date: 20-01-2008

End Date: 30-06-2008

Program Area: Farming System

Commodity: Mungbean, Ground nut

Objectives:

To determine the suitable planting arrangement of groundnut and mungbean in intercropping systems and to assess the economic benefit of the systems

Methodology:

The experiment was conducted at farmer’s field of MLT site, Laxmipur during the Rabi season of 2008-09. The soil of the experiment area belongs to Young Meghna Estuarine Floodplain (AEZ 18 f) and Meghna Estuarine Floodplain (AEZ 18), respectively. The treatments are as follows: T₁: Sole Groundnut, T_2: Sole Mungbean, T₃:100% Groundnut + 20% Mungbean, T₄: 100% Groundnut + 40% Mungbean, T₅: 100% Groundnut+ 60% Mungbean. The cultivar of groundnut was Dhaka-1 and mungbean BARI Mungbean-5. The crops were sown on last week of January in 2009. Spacing of groundnut was maintained at 40 cm × 10 cm. The spacing of mungbean was varied according to treatment-to-treatment. Row to row distance was 40 cm and plant to plant was maintained as 5cm, 50 cm, 25 cm and 12 cm as according to the treatment T2 {Sole groundnut (100%)}, T3 (100% groundnut + 20% mungbean), T4 (100% groundnut+ 40 % mungbean), T5 (100% groundnut+ 60 % mungbean) respectively. The land was fertilized with 20-30-25-7 kg ha^-1(N-P-K-S), the whole amount of P, K, S and half of N was applied at the time of final land preparation and remaining was applied at 30 DAS. Harvesting data varied from treatment to treatment and crop to crop. Groundnut equivalent yield, land equivalent ratio (LER) and economic analysis were done for each treatment on a hectare basis considering the market rate of crop. Data on yield and yield contributing characters were recorded and analyzed statistically.

Achievement/Findings:

The highest pods per plant (21) were found in sole groundnut which was statistically similar with 100% groundnut + 20% mungbean (19.50) and 100% groundnut + 40% mungbean (18.33) and lowest (15.33) was found in 100% groundnut + 60% mungbean. The highest number of seeds per pod (1.77) was found in sole groundnut which was statistically similar with 100% groundnut + 40% mungbean (1.71) and the lowest (1.62) was found in 100% groundnut + 60% mungbean. The highest groundnut yield was obtained from sole crop (2.35 t ha^-1) which was statistically different than the other intercropping combination but lowest was found in T₅ (1.74 t ha-1). All the intercropped system showed higher groundnut equivalent yield than sole groundnut except 100% groundnut + 60% mungbean. The highest groundnut equivalent yield was recorded from 100% groundnut + 40% mungbean (2502 kg ha^-1) and lowest in 100% groundnut + 60 % mungbean (2203 Kg ha-1). The highest gross return and gross margin were obtained from 100% groundnut + 40 % mungbean though cost of cultivation was higher than sole groundnut. The highest LER was found in 100 %groundnut + 40% mungbean and lowest in 100% groundnut + 60% mungbean.
