| Abstract | ||||
| Appropriate nutrition in early autumn season under high temperature conditions has a major effect on cauliflower yield and quality. Thus two field experiments were conducted during autumn 2018 and 2019 seasons at a private farm in Demiana village, Belqas district, Dakahlia governorate to investigate the influence of foliar application with nitrogen micro carbon (NMC) at 0, 300, 600 and 900 ppm) and boron (B) at 0, 10 and 20 ppm and their interaction on vegetative growth characters, leaves chemical contents, curds yield and quality. This study contains 12 treatments with three replicates arranged in split plots in a complete randomized block design. Nitrogen micro carbon was assigned in the main plots, whereas the boron was randomly located in sub plots. Obtained results cleared that interaction impact between NMC and B significantly affected on vegetative growth (plant height, foliage fresh weight, No. of leaves, leaves fresh weight, leaves area and leaves dry matter), chemical contents of leaves (N, P, K, chlorophyll a, chlorophyll b and carotenoids), curds yield and physical characters (curd weight, diameter compactness rate, yield and hollow stem) and curds quality (dry matter, Vit. C, acidity and TSS). In this concern, combination between nitrogen micro carbon at 600 ppm and Boron at 20 ppm gave the highest values of previous parameters except hollow stem percentage where between NMC at 0 ppm and B at 20 ppm gave the lowest percentage of hollow stem. | ||||
