Abstract

A field experiment was carried out during the two successive summer seasons of 2017and 2018 in private sector farm at Kom Hamada city, Buhera Governorate, Egypt to investigate the effect of organic fertilizers tea (Chicken manure tea , Rabbit manure tea , Compost tea, Biochar tea and without organic fertilizers tea) as soil additions and  foliar spray with boron at 0, 50 and 100 mg L-1  as well as their interaction on growth, yield and quality of potato tubers (Solanum tuberosum L.) cv. Beleny. Obtained results showed that, soil addition with chicken manure tea and foliar spray with high concentration of boron (100 mg L-1) gave the highest values in vegetative growth parameters. Moreover, application of either chicken manure or rabbit manure tea with the recommended rate of NPK and foliar spray with boron at 100 mg L-1 recorded the highest increases in the tuber yield of potato. But the best chemical components of potato tubers (N, P, K, carbohydrates and starch) verified when using chicken manure tea and foliar spray with boron at 100 mg L-1 compared with all other treatments and in both seasons.
