Response of cotton plant (Giza 88 cultivar) to NPK fertilizers after berseem and faba beans as preceding winter crops [electronic resource].

Includes references.

TWO FIELD experiments were carried out at Bassyoun Centre, El Gharbia Governorate in 2003 season and repeated in 2004 season, to study the effect of NPK rates on leaf nutrient contents, growth, yield and yield components of the Egyptian extra long staple cotton cultivar, Giza 88 after berseem and faba beans as preceding winter crops. Six treatments for each experiment were applied and the experimental design was randomized complete blocks with four replicates. The best NPK rate with clover preceding cotton was(7S kg N + 13.1 kg P +40 kg K)/fed. However, the best rate with faba beans preceding cotton was(30 kgN+13.1kg P+ 40 kg K)/fed. The results indicated that NPK rates significantly increased leaf N, P, K, Ca, Fe, Mn an Zn contents in each experiment, Plant height at harvest and number of fruiting branches/plant were positively affected by NPK rates. The same treatments had significant effects on number of open bolls/ plant and seed cotton yield; plant as well as/fed.
