| Abstract | ||||
| The main purpose of this work was to study the effect of foliar nutrition with calcium and some micronutrients (Fe, Zn, Mn) on potato (Solanum tuberosum, L.) production and quality. Two successive field experiments were conducted at Met-Antar village Talkha, Dakahlia Governorate, during the two summer seasons of 2000 and 2001. The experimental design was a split plot with four replications. The obtained results show marked and significant increases in tuber yield per fed. with foliar spraying treatments. Foliar spraying by calcium and micronutrients caused also increases in N, P, K and Ca percentage in leaves during the two seasons. The results indicate that Fe, Zn and Mn content in potato leaves were increased with foliar spraying by Fe, Zn and Mn separately or together. There was a tendency towards increasing N, P and K content in tubers with foliar spraying by Ca, Fe, Zn and Mn separately or together. As for specific gravity of potato, foliar spraying by Ca and micronutrients caused an obvious reduction in the two seasons. On the other hand, starch content in potato tuber was not affected by foliar spraying. | ||||
