Abstract

Abstract The field study was conducted during the year 2023, to study Effect of nanofertilization on the yield and its components in six cultivars of upland cotton under 5% selection intensity and to estimate the coefficient of variation for the studied traits of seed cotton yield by Effect of nanofertilization, and the cultivars are (Coker, IK30, MONTANA CHRIB-AM, 539, ALEPPO 9, CUTRUR). Seeds of the cultivars were planted in Babil Governorate using a factorial experiment according to a randomized complete block design (RCBD) with three replicates. The results of the statistical analysis showed that there were highly significant differences in the averages of the cultivars for all the studied traits, as the CHRIBAM539 cultivar excelled in the number of bolls open, bolls open weight, earlyness factor, ginning outturn percentage, seed cotton yield per plant, and plant yield (microgram hectare-1), followed by the IK30 cultivar, bolls weight, and in ginning outturn percentage (gm per plant) and the Halab 9 cultivar was superior in chlorophyll percentage, while the Coker cultivar was excelled on the seed factor, while the Cutrur cultivar was non excelled in any of the studied traits. The concentration of (2) g.L-1 of nanofertilization with half the fertilizer recommendation achieved the highest cotton yield per plant with the CHRIBAM539 cultivar, followed by the MONTANA cultivar, reaching (209.9) (173.6) respectively. Interactions between cultivars and nanofertilization with half the ground fertilizer recommendation gave highly significant differences in the number of bolls, bolls weight, seed factor, earliness factor, fiber yield, ginning outturn percentage, and seed cotton yield.
