Abstract
An experiment was conducted to study the effects of different rates of nitrogen and phosphorous on the nodulation and growth of soybean. The pot experiment was conducted under a rain shelter in Agro Technology Park, Eastern University, Sri Lanka. The experimental design was CRD with four replicates. Different fertilizer combinations were used as treatments such as T1-30N:150P: 75K: kg/ha, T2-70N:150P:75K: kg/ha, T3 (control)-50N:150P:75K: kg/ha, T4-50N:125P:75K: kg/ ha and T5-50N:175P:75K: kg/ha. The results revealed that there were significant (p
Highlights
Soybean (Glycine max L.) is known as an important crop worldwide
Plant height was decreased when the amount of N is decreased in fertilizer combination
The changing of rate of N and P fertilizer combination was affected the plant height
Summary
Soybean (Glycine max L.) is known as an important crop worldwide It is used as a good source of vegetarian protein as well as vegetable oil. Plant growth and seed yield of soybean increased when nitrogen was initially added [2]. Nitrogen (N) fertilizer can increase the production of total dry matter, which can improve the potential of plant to produce more pods, seeds and grain yield [3]. Cultivation of soybean is very low in Batticaloa district due to its poor germination as well as poor yield It may be increased using more amounts of.

The experiment was conducted to study the effects of different rates of nitrogen and phosphorous on the nodulation and growth of soybean
