Abstract/ Executive Summary:

The experiment was conducted at BINA Sub-station farms, Ishurdi and Magura during March to May 2017 to investigate the response of mungbean to different concentrations of chitosan on yield and yield contributing characters. Four different concentrations of chitosan viz., 0, 50, 75, and 100 ppm were sprayed at pre-flowering stage of two mungbean varieties, Binamoog-7 and Binamoog-8. The experiment was laid out in randomized complete block design with 3 replicates. The influence of foliar application of chitosan on plant height, number of pods plant^-1, 1000-grain weight and seed yield was significant and branch number, pod length and number of seeds pod^-1 was non-significant. Seed yield was higher in chitosan applied plants than control plants where 100 ppm showed the highest. Binamoog-8 showed higher seed yield than Binamoog-7 at both locations. Binamoog-8 produced the highest seed yield with 100 ppm at Magura and Binamoog-7 showed the highest seed yield with 100 ppm both at Magura and Ishurdi. This result indicates that 100 ppm may be the optimum concentration of chitosan for maximizing the yield of mungbean.

Keywords: Mungbean, Chitosan, Yield attributes, Yield

Location: BINA substations Ishurdi and Magura

Start Date: 01-03-2017

End Date: 31-05-2018

Program Area: Variety and Species

Commodity: Mungbean

Objectives:

To investigate the response of mungbean to different concentrations of chitosan on yield and yield contributing characters

Methodology:

The experiment was conducted with two mungbean varieties at BINA Sub-station farms, Ishurdi and Magura during March to May 2017. Four different concentrations of chitosan viz., 0, 50, 75, and 100 ppm were sprayed at pre-flowering stage of two mungbean varieties, Binamoog-7 and Binamoog-8. In control, water was sprayed as per treatment. The experiment was laid out in randomized complete block design with 3 replicates. The unit plot size was 2 m × 3 m and plant spacing was 30 cm × 10 cm. Recommended doses of fertilizers were applied and cultural practices were done as and when necessary. Yield and yield contributing characters were recorded from five plants in each plot at the harvest. Grain yield was recorded on plot basis and converted in kg ha^-1. Data were analyzed statistically.
