Dry matter yield and number of pods per plant were also significantly affected by the different levels of compost and N- fertilizer rates. The results of the soybean grain yield and yield components showed that the crop responded positively to the application of both compost and N – fertilizer, but soybean response to compost fertilizer was higher than that of N- fertilizer. The highest seed number per plant of (160. 9g) was produced by variety TGX 1740- 2F while the highest numbers of pods were produced from the application rate of 2 and 4t/ha compost. Application rate of 4t/ha compost produced the highest number of seed per plant of (154. 4g).The optimum performance of soybean grain was obtained from application of 2 or 4 t/ha of compost.
