| Abstract | ||
| An experiment was conducted during two seasons ( Spring and Autumn) of 2014 in private field in Babil province , Al-Hashimia district, to study the effect of organic fertilization (Residues of date palm fronds ) and the chemical fertilization ( N,P,K) on the growth and yield of potato var. Safaran. This experiment was designed according to (R.C.B.D) with three replicates and two factors. The first included three levels of organic fertilizer ( Zero, 16 , 32 ton.hectar-1), and the second factor was four levels of Chemical fertilizer N,P,K ( Zero ,50% , 75% and 100% of the recommended quantity). The organic and chemical fertilizer treatment (32 ton.hectar-1+ 100% of N,P,K ) gave highest chlorophyll content , dry weight of vegetative growth and marketable yield ( 76.08 mg.g-1 , 57.70 g and 40.74 ton.h-1 respectively). While treatment (16 ton.hectar-1+ 100% of N,P,K) gave highest plant height, percentage of phosphorus ( % P) and protein percent in tubers (52.20 cm , 0.552% and 2.082% respectively), as compared to control treatment which gave lowest values in spring season. Results showed in autumn season, that organic and chemical fertilizers (16 ton.hectar-1+ 100% of N,P,K) gave highest number of tubers , percentage of phosphorus (% P) and protein content of tubers (6.3 tuber, 0.428% and 1.455% respectively). While treatment (32 ton.hectar-1+ 75%) recorded highest average plant height ( 64.87cm) and the treatment (32 ton.hectar-1+ 100% ) recorded highest average to marketable yield (35.93 ton.h-1). While the treatment (16 ton.hectar-1+ 75% of N,P,K ) gave highest percentage of phosphorus (% P) in leaves (0.702% , 0.469%) for both seasons respectively as compared to control treatment which gave lowest values. | ||
