Response of Fertilization of Nitrogen on Agronomical Attributes of Soybean

Abstract

Soybean also known golden bean is a dual purpose crop grown to meet the requirement of both high protein and oil content. Fertilizers are one of the important components of farming system due to their requirement to provide essential nutrients to crop. The current research work was done to study the effect of the different rates of nitrogen fertilization on the growth and yield of soybean were studied. Field experiments were conducted at Instructional Research Farm, Krishi Nagar, Jabalpur, Madhya Pradesh, India during kharif season in the month of July to October in the year 2019‒2020. This research has been conducted in order to examine the beneficial effects of additional application of nitrogen at grain development stage on yield attributes and yield of soybean. The experimental material was early maturing variety of soybean JS 20-34. Treatments were given in 12 combinations in the split plot design. Plant samples were collected at R1 and R3 for dry matter yield and nitrogen determination. Grain yields were determined and grain samples were collected at harvest. A positive grain yield in response to nitrogen fertilizer was observed in different treatments. These imply that additional nitrogen applications are important for getting higher yields. In the current research we came to the conclusion that additional nitrogen fertilizer application to soybean crop has positive impact on several agronomical attributes of the crop.
