Foliar and Soil Fertilization Effect on Seed Yield and Protein Content of Soybean

M.A. Mannan
Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur-1706, Bangladesh

Abstract/ Executive Summary:

A field experiment was carried out at Agronomy Farm of Patuakhali Science and Technology University, Dumki , Patuakhali from December 2011 to March 2012 to study the effects of nutrient foliar spray on soybean growth, yield and protein content. Soybean variety Shohag was used as the test crop. N, NPK, NPKS and NPKMg were sprayed and applied in the soil at vegetative and pod filling stages. Soil fertilizations were done as recommended dose, and no soil and foliar fertilization were considered as control. Plants were sprayed at the rate of 100 mg/L of water corresponding to each nutrient. The experimental design was a split plot with three replications. Result indicated that nutrient foliar spray, either singly or in combination, enhanced the growth and yield of the soybean as well as protein content in soybean seed, at the two growth stages compared to soil fertilization. However, spraying nutrients during pod filling stage was better than vegetative spraying stage in all characters studied. The highest amount of protein content in soybean seed and grain yield were obtained by spraying NPKMg.

Keywords: Soybean, Yield, Protein content, Foliar and soil fertilization

Location: Dumki , Patuakhali

Start Date: 00-12-2011

End Date: 00-03-2012

Program Area: Crop-Soil-Water Management

Commodity: Soybean

Objectives:

To assess the effect of foliar nutrient spray singly or in combinations before flowering and pod filling stages, on the growth, yield and seed quality of soybean.

Methodology:

The field experiment was carried out at Patuakhali Science and Technology University, Dumki , Patuakhali from December 2011 to March 2012. The soybean variety used was Shohag. The experimental design was split plot having 4 m x 2.5 m plot size with three replications.Each block was divided into main plots where growth stages (vegetative and pod filling) and six subplots to which nutrients were foliarly applied as exclusively N, NPK, NPKS and NPKMg at the rate of 100 mg litre^-1 of each nutrient were randomly assigned. Planting of seeds was done on 03 December, 2011 maintain spacing 30 cm x 5 cm. Weeding was done at 2 and 6 weeks after sowing (WAS). Plants were sprayed at vegetative (4 weeks after sowing) and pod filling (8 weeks after sowing) stages as per treatment. Ten selected plants were used to take the data from each plot of each replication. Data were recorded for grain yield, plant height, dry weight of different plant parts, number of pods plant^{- 1}, number of seeds pod^-1 and 100 grain weight were recorded for grain yield, plant height, dry weight of different plant parts, number of pods plant^{- 1}, number of seeds pod^-1 and 100 grain weight. The nitrogen concentration in seeds was measured with micro-Kjeldahl method as described by Peach and Tracey (1956) and the seed protein content was determined by multiplying the nitrogen percentage and protein factor using the formula, Protein percentage = Nitrogen percentage x 5.71 (Breese, 1931). Data collected were analyzed using MSTAT- C program. The means differences among the treatments were compared by least significance difference test (LSD).

Achievement/Findings:

Result indicated that nutrient foliar spray, either singly or in combination, enhanced the growth and yield of the soybean as well as protein content in soybean seed, at the two growth stages compared to soil fertilization. However, spraying nutrients during pod filling stage was better than vegetative spraying stage in all characters studied. The highest amount of protein content in soybean seed and grain yield were obtained by spraying NPKMg.
