| Abstract | ||
| two field experiments were carried out during two fall seasons of 2004/2005 and 2005/2006 on potato (variety Spunta) at Kafr Meet Faris village, Mansoura, Dakahlia Governorate to study application effect of some organic manure sources and foliar spraying with mixture of micro-nutrients (Fe, Zn and Mn) in addition to their interaction on vegetative growth characters, yield and its components, as well as tubers quality and some chemical concentrations in tubers. Results indicated that plant length (cm), number of main stems/plant, number of leaves/plant, foliage fresh weight/plant (gm), number of tubers /plant, tuber weiqht average (gm) and total tubers yield (tons/fed), as well as con.ents of N, P and K (%) in tuber were si~nif.cantIY increased in both seasons by using the chicken manure at rate of (10m Ifed). On the other hand dry weight of tuber (%) was affected significantly in the two study seasons by using (50% of cattle manure + 50% of chicken manure). Micro-nutrients concentration of Fe ,Zn and Mn (ppm) in tuber increased significantly by using cattle manure at rate of (20 m3/fed) , while, foliage dry weight/plant (gm) and T.S.S. of tuber were not affected by the different organic manures. Application of foliar spraying three times by mixture of chelated micro- nutrients Fe, Zn and Mn (1:1:1) at concentration of (150 ppm) led to significant increases of the plant length, number of main stems/plant, number of leaves/plant, foliage fresh weight/plant, foliage dry weight/plant, total tubers yield, number of tubers/plant, tuber weight average, percentage dry weight of tuber, T.S.S. and the tuber concentration of N, P, K (%), Fe, Zn and Mn (ppm) in both seasons. The interaction between organic manures and foliar spraying by mixture of micro-nutrients indicated that the vegetative growth characters, total tubers yield , number of tubers/plant, tuber weight average, percentage dry weight of tuber and T.S.S. of tuber were significantly affected by using the chicken manure at rate of (10 m3/fed) together with foliar spraying three times by mixture of chelated micro-nutrients Fe, Zn and Mn (1: 1:1) at concentration of (150 ppm) during the two fall seasons. | ||
