| Abstract | ||||
| This study was carried out during 2014 and 2015 seasons to examine the effect of nano NPK fertilizers against conventional NPK ones on growth and fruiting of Zaghloul date palms grown under Minia region conditions. N, P and K as nano and conventional were added at 500& 1000, 250&500 and 250&500 g / palm/ yr., respectively. The data reveal that, N at 500 & 1000 g / palm / yr. with both P and K at 250 & 500 g/ palm/ yr. either single or combined via nanotechnology material was superior in enhancing growth, yield and fruit quality than using these nutrients as conventional fertilizers. Increasing levels of N from 500 to 1000 g / palm/ yr. as well as both P and K from 250 to 500 g/ palm/ yr. had meaningless promotion on the aforementioned characteristics under nano system, The vice versa was noticed with NPK applied as conventional form. The best treatments in improving growth, yield and fruit quality of Zaghloul date palms when added NPK as nanotechnology system as compared with conventional form. Generally, from these results the data presented that nano NPK fertilizers each at 500, 250 and 250 g. /palm /yr., respectively is a better than application of conventional NPK at 1000 , 500 and 500 g./ palm/yr., respectively to enhance growth, yield and fruit quality of Zaghloul date palms grown under Minia region conditions. | ||||
