Abstract/ Executive Summary:

The experiment was carried out at the Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI) , Jessore to evaluate the performance of different varieties of hybrid maize under intercropping systems with groundnut in Rabi seasons for higher productivity and profitability. Four sole crops of hybrid maize varieties viz., BHM-1, BHM-3, Pacific-11, and Pacific-984, one sole crop of groundnut (var. Jhingabadam) and eight intercropping systems of maize + groundnut under two planting methods viz., normal and paired row made 13 treatments, were used for two consecutive years (2004 and 2005). Treatments were arranged in a randomized complete block design with four replications. Among the intercropped treatments, four rows groundnut in between paired rows of hybrid maize var. Pacific 11 showed higher total dry mater (TDM), leaf area index (LAI), crop growth rate (CGR), gross return , net return and benefit cost ratio (BCR) than the other planting systems tested in the experiment.

Objectives:

To study the performance of different varieties of hybrid maize under intercropping systems with groundnut for higher productivity and profitability.

Methodology:

The experiment was conducted at the Regional Agricultural Research Station, BARI, Jessore during two consecutive Rabi seasons of 2003-04 and 2004-05. There were 13 treatments, viz., 4 sole crops of hybrid maize (Zea mays L.), one sole crop of groundnut (Arachis hypogaea L.) and 8 intercropping systems of maize+ groundnut under two planting systems viz, normal and paired row. The experiment was laid out in a randomized complete block design with four replications in Rabi season. The data recorded for different characters were compiled and tabulated in proper way for statistical analysis. The significance of comparison was tested with 'F' test and whenever the variance ratio was found significant, means were. compared by Duncan Multiple Range Test (DMRT). The data were analyzed statistically following computer package MSTAT-C and DMRT was used to determine the significant differences among the treatment means.

Achievement/Findings:

Leaf area index (LAI) was significantly influenced by all the intercropping systems in maize and groundnut at different harvests in both the years . The LAI of maize and groundnut reached maximum at 120 and 150 DAS, respectively, with the increasing number of leaves per plant and expansion of individual leaf . At the later stage of growth, LAI reduced slowly in maize but sharply in groundnut. LAI of maize decreased due to intercropping, but there was no remarkable difference between the sole and intercrop maize in both the years. The maximum LAI (4.97 in 2003-04 and 5.88 in 2004-05) was obtained from sole hybrid maize (var. BHM-3). Cost and benefit analysis is an important tool for evaluating the economic feasibility of intercropping systems. Data showed that T7 (four rows of groundnut in between two paired rows of hybrid maize var. Pacific 11) gave the highest benefit cost ratio (BCR) of 3.79 in 2003-04 and 3.91 in 2004-05 followed by T6 (four rows of groundnut in between two paired rows of hybrid maize var. BHM- 3) of 3.56 in 2003-04 and 3.79 in 2004-05. Similar findings were reported by Sharma (1994). Maize hybrid variety as sole crop gave reasonable good yield and economic return but due to sustaining of soil fertility as well as ensures productivity from hybrid maize, intercropping with legumes is one of the way which could help in yield stability. In this situation, four rows of groundnut in between two paired rows of hybrid maize var. Pacific 11 (T 7) would be better option in Rabi season.
