Effect of Mung Bean Intercropping with Upland Cotton

Md. Rezaul Amin

Cotton Research, Training and Seed Multiplication Farm, Sadarpur, Dinajpur

Abstract/ Executive Summary:

An experiment was carried out in the field at Cotton Research, Training & Seed Multiplication Farm, Sadarpur, Dinajpur during the growing season of July 2011 to March 2012 to find out the technique of intercropping mung bean with upland cotton. The treatments were: T₁. Rupali 1–Mung bean, T₂. DM 1–Mung bean, T₃. CB 12-Mung bean, T₄. CB 10–Mung bean, T₅. Rupali 1 (Sole), T₆. DM 1 (Sole), T₇. CB 12 (Sole), T₈. CB 10 (Sole) and T_9. Sole mung bean. The seed cotton yields did not respond significantly among the treatments of cotton intercropping as well as sole cotton. The highest grain yield of mung bean (702 kg/ha) was obtained from the sole mung bean than other treatments due to cause of higher number of plants per square meter. Mung bean intercropping with cotton produced higher seed cotton equivalent yield, gross margin and gross return for local varieties as well as hybrid lines. The lowest gross return, gross margin and BCR were obtained from the treatment of sole mung bean. Mung bean should be intercropped would cotton for increasing productivity and profitable benefit returns which ultimately would encourage farmers for sustainable cotton cultivation in Bangladesh.

Location: Sadarpur, Dinajpur

Start Date: 01-07-2011

End Date: 30-06-2012

Program Area: Farming System

Commodity: Cotton, Mungbean

Objectives:

Cotton is one of the most important commercial crops in the world but it is not popular in Bangladesh shadowed by the top priority given for food crops to meet the ever increasing demand of food. Much works have been done on cotton as a sole crop or mono crop, but there is scarcity of information on cotton based intercropping or cropping patterns. Therefore, this research work was aimed at intercropping of cotton with mung bean for better productivity and efficient utilization of land and to test cotton-mung bean intercropping for sustainable cotton cultivation.

Methodology:

The test crops were Cotton and Mung bean. Certified seeds were collected for cotton from the Cotton Research, Training and Seed Multiplication Farm, Cotton Development Board, Sadarpur, Dinajpur, Jagodishpur, Jessore and local market, Mung bean seeds were collected from Wheat Research Center, BARI, Dinajpur. Cotton and Mung bean varieties were used CB 10, CB 12, Rupali 1, DM 1 and BARI Mung 06 respectively. The experiment was set up in randomize complete block design with four replications. There were altogether 36 (9 X4) unit plots, each plot measuring was 4.5 m X 3.6 m. Outside border, inter-replication and inter-plot spacing were 2 m, 1.8 m and 1.5 m respectively. The treatments were: T₁. Rupali 1–Mung bean, T₂. DM 1–Mung bean, T₃. CB 12–Mung bean, T₄. CB 10–Mung bean, T₅. Rupali 1 (Sole), T₆. DM 1 (Sole), T₇. CB 12 (Sole), T₈. CB 10 (Sole) and T₉. Sole mung bean.The data were analyzed statistically by "MSTATC".

Achievement/Findings:

The highest seed cotton equivalent yield (2.66 t/ha) was obtained from DM 1 intercropping with mung bean, which was followed by CB 10 and CB 12 intercropping with mung bean and lowest (0.70 t/ha) was found in sole mung bean. The highest total gross return (1,82,700 Tk/ha) was obtained from the treatment of DM 1 with mung bean intercropping, which was followed by CB 12 with mung bean intercropping and the total lowest gross return (49,000 Tk/ha) was observed from sole mung bean. Cotton intercropping with mung bean Rupali 1, DM 1, CB 12 and CB 10 produced 25, 44, 12 and 15 percent higher total gross return than monoculture cotton and 229, 273, 253 and 212 percent higher than monoculture mung bean respectively. The highest total gross margin (85,720 Tk/ha) was obtained from the treatment of CB 12 with mung bean intercropping, which was followed by sole cotton CB 12 and the total lowest gross Margin (19,920 Tk/ha) was observed from sole mung bean. Cotton intercropping with mung bean Rupali 1, DM 1, CB 12 and CB 10 produced 11, 28, 0.43 and 3 percent higher total gross margin than monoculture cotton and 235, 273, 330 and 230 percent higher than monoculture mung bean respectively. Benefit cost ratio (BCR) was higher (2.24) in the sole cotton CB 12 followed by the treatments of DM 1 with mung bean intercropping and the lowest BCR (1.69) was recorded from the treatment of sole mung bean.
