Abstract
The present investigation was carried out at Shandaweel Agric. Res. Station (Sohag Governorate), A.R.C., Ministry of Agriculture, Egypt A.R.E., during the two successive seasons of 2014 and 2015 to study the effect of planting date, fertilizers rates and splitting fertilizers on shedding, metabolism activity, yield and its components on Egyptian cotton (Gossypium barbadense L.) variety Giza- 90. Each season contained two separate experiments represented in two sowing dates i.e. on 20thMarch and 20thApril. The variables in each experiment were distributed in randomized complete block design (RCBD) using split plot arrangement with 4 replicates. The variables studied in each planting were fertilizers rates and splitting fertilizers. The first variable was fertilizers rates which were allotted in the main plots. The treatments were distributed as follows:1) 50 kg N + 24 kg K2o /fed. 2) 50 kg N + 24 kg K2o /fed. + Spray micronutrients (200g /fed.).3) 70 kg N + 36 kg K2o /fed.4) 70 kg N + 36 kg K2o /fed. + Spray micronutrients (200g /fed.). The second variable was the fertilizer splitting of N & K. This variable occupied in the sub-plots. The treatments were distributed as follows:a) Splitting the fertilizer rates into two equal parts before the second and the third irrigation.
