Abstract/ Executive Summary:

A field experiment was conducted at the experimental farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during the period from April, 2013 to July, 2013 to study the growth and yield of Mungbean as influenced by potassium (K) and sulphur (S). Four levels of K (0, 15, 25 and 35 kg ha^-1) and three levels of S (0, 3 and 6 kg ha^-1) were used in the study.The results revealed that grain and stover yield of mungbean increased with increasing levels of K and S.The maximum significant grain and stover yield were obtained with the treatment combinations K₂S₂ (25 kg K ha^-1 + 6 kg S ha^-1 ) and the same treatments combinations gave the highest plant height, number of branch plant^-1, yield attributes like number of pods plant^-1, number of grains pod^-1, weight of 1000 seeds.

Keywords: Mungbean, Potassium, Sulphur, Growth, Yield

Location: Experimental farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207

Start Date: 01-04-2013

End Date: 31-07-2013

Program Area: Crop-Soil-Water Management

Commodity: Mungbean, Fertilizer

Objectives:

To study the growth and yield of Mungbean as influenced by potassium (K) and sulphur (S)

Methodology:

The experiment was conducted in the experimental farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during the period from April, 2013 to July, 2013. The experimental soil was silty clay loam in texture having pH 6.14 and organic carbon content is 0.68%. The area represents the Agro-Ecological Zone of Madhupur tract (AEZ-28) with PH 5.8-6.5, ECE-25.28. The high yielding variety of mungbean (BARI mung-6) was used for this experiment and it was released by Bangladesh Agricultural Research Institute, Joydebpur, Gazipur in 2003. It is photo insensitive, semi synchronous maturity, short lifespan (60 to 65 days) and bold seeded crop. Its yield potentiality is about 2 t ha^-1. This variety is resistant to yellow mosaic virus diseases, insects and pest attack. The experiment consisted of two factors: Factor A: four levels of Potassium (K), K₀ = No potassium, K₁ = 15 kg K ha^-1, K₂ = 25 kg K ha^-1, K₃ = 35 kg K ha^-1 and Factor B: three levels of Sulfur (S), S₀ = No sulphur, S₁ = 3 kg K ha^-1, S₂ = 6 kg K ha^-1. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Recommended blanket doses of N, and P (20 kg ha^-1 N from urea, 80 kg ha^-1 P from TSP, respectively) and cow dung as manure were applied. The whole amounts of TSP and half of Urea fertilizer were applied as basal dose during final land preparation. The rest of half urea was applied 25 days after sowing (DAS). The required amounts of K (from MOP) and S (from Gypsum) were applied at a time as per treatment combination after field layout of the experiment and were mixed properly through hand spading. Mungbean seeds were sown on 18th April 2013 in lines following the recommended line to line distance of 30 cm and plant to plant distance of 10 cm. Various intercultural operations such as thinning of plants, weeding and spraying of insecticides were accomplished whenever required to keep the plants healthy and the field weed free. The crop was harvested at maturity on 18th June 2013. The collected data were analyzed with the help of MSTAT-C program and mean values of all the parameters were adjusted by Duncan’s Multiple Range Test (DMRT) at 5% level of probability.

Achievement/Findings:

Based on the results of the present study, it may be concluded that, application of K and S @ 25 kg K ha^-1 and 6 kg S ha^-1(i.e. MOP 50 kg ha^-1 and Gypsum 33.34 kg ha^-1) may be the best combination for higher yield of mungbean and also to maintain soil fertility and productivity than their individual application.
