Combined Effect of Organic and Mineral Fertilization on Nodulation and Yield of Common Bean (Phaseolus vulgaris L.) under Sandy Soil Conditions.

Abstract

This study was carried out on sandy soil of El- Maraka village, El- Tahreer region, Behara Governorate, Egypt to define the pest application time of organic (molase and vinase) and mineral (P + Micronutrients) to two cultivars (Karnack and Nebraska) of common bean plants (phaselus volgaris L) and their effect on plant growth, productivity and seeds quality. Fresh and dry matter yields as well as the content of N, P, K, Mn, Zn and Cu were determined for the plant samples at 45 and 70 days. Also, nodules number at growth period of 45 day. Seeds contents of N, P, K, Mn, Zn, Cu and protein were determined. The data of this study show the importance of both organic and mineral fertilizer to increase sandy soil productivity of common bean plants and improved its quality. Nebraska cultivar was more suitable and high productivity under sandy soil conditions compared with Karnack cultivated. The latter applications of both organic and mineral fertilization were more high efficiency than of earlier application.
