Effect of spraying with balanced nano fertilizer and boron on yield and chemical characteristics of two hybrids of cabbage Brassica oleracea var. capitata L.

Abstract

This study was conducted during agricultural season 2021-2022 at the research station of Department of Horticulture and Landscape/ College of Agriculture/ Tikrit University, to study the effect of foliar application of balanced nano-fertilizer and boron on two hybrids of cabbage Brassica oleracea var. capitata L. The experiment included three factors, the first factor is three concentrations of balanced nano-fertilizer viz, 0, 20 and 30 g L-1 the second factor is spraying of boron at two concentrations namely, 0 and 5 mg L-1. The third factor is using two hybrids namely, Dlal and Globe Master. The experiment was laid out according to Randomized Completed Block Design (R.C.B.D.) With split plot arrangement with three replications. The results showed that, the spraying with boron at 5 mg L-1 concentration led to a significant increase in the total head weight, marketable head weight, head circumference, total plant yield, and nitrate ratio. The hybrid Dlal had highest values in all studied characteristics except the nitrate percentage compared with the hybrid Globe Master.
