| evaluate effects of Compost and/or biofeed in combination with graded proportions of mineral NPK fertilizers on growth and yield components of Super Giza 94 Egyptian cotton cultivar. Application of compost was added during soil preparation, Biofeed (as a liquid) was added after planting with irrigation water, mineral NPK fertilizers was applied as the recommended dose as control. The treatments were, [1] Control 100% mineral NPK, [2]75% Mineral + 25 % Compost, [3] 75% Mineral + 25 % Biofeed, [4] 50 % Mineral + 25% Biofeed + 25% Compost, [5] 25 % Mineral + 50 % Biofeed + 25% Compost [6] 50 % Biofeed + 50% Compost). Results showed that treatment No.[4] gave the highest values of Chlorophyll a (4.94 and 4.95), Chlorophyll b (3.05 and 3.13), Carotenoids (1.23 and 0.96), Total soluble sugar (17.91 and 18.50), plant height (142.25 and 130.06) No. of fruiting branches (17.62 and 17.64) , No. of open bolls (28.67 and 25.31) , % Earliness (61.82 and 58.05), Seed cotton yield / kentar (9.51 and 8.49), boll weight (2.42 and 2.50) , seed index (14.05 and 11.03) and lint % (38.61 and 41.10) respectively in the first and second seasons compared with other treatments and control. | ||
