| Abstract | ||
| Field experiment was carried out in new reclaimed lands at the experimental Station of National Research Centre in Nubaria Region, Behira Governorate, North of Egypt, during the two growing seasons of 2017/2018 and 2018/2019. This studyaimed to enhance cassava(Indonesian cultivar) productivity by using differentsources of potassium fertilizers treatments. Six treatments, i.e.,potassium sulphate as mineral fertilizer, K feldspar + bio fertilizer as bio fertilizer, compound K, Aloe extract as natural fertilizer and Humic acid as organic fertilizer were compared to non-potassium fertilizerapplication (control). The experiments were carried out in a Complete Randomized Blocks Design in four replicates. The characters of vegetative growth, (plant height, leaves number per plant, main stems number per plant, main stem diameter,leaves dry matter, total chlorophyll content and leaf area) total yield per fed., tuber roots characters (average tuber roots number, average tuber roots diameter, average tuber roots length, average tuber roots weight and tuber roots dry matter) and chemical contents of tuber roots (starch % and potassium %)were evaluated.The increment in vegetative growth and productivity of cassava plants was evident with fertilizered plantsby mineral potassium, Aloe extract and Humic acid. On the other hand, decrement in vegetative growth and productivity of cassava was observed withnon-adding potassium fertilizertreatment (control). | ||
