Abstract

Cauliflower (Brassica oleracea L. var. botrytis) a cool season vegetable which belongs to the family Cruciferae or Brasicaceae. It is grown in winter season. It is originated from Europe and developed from broccoli. It is a vegetable crop grown for its edible white and tender curd developed from short floral parts. It is very sensitive to low temperature and high heat. The aim of this study is to determine the effect of foliar application of boron, iron and molybdenum on cauliflower growth, quality and yield. The study was carried out in Vegetable Research Area of Institute of Horticultural Sciences, University of Agriculture Faisalabad in 2019-2020. Seedlings of 30 days were raised then transplanted to field in Randomized Complete Block Design (RCBD) using three replicates. Different doses of micronutrients were applied as foliar spray like boron (0.2%, 0.5%), iron (0.2%, 0.5%) and molybdenum (0.1%, 0.3%) on cauliflower. The data for different vegetative and biochemical parameters including plant height (cm), number of leaves plant-1, number of days taken from transplantation to curd formation, days to curd initiation to maturity, foliage fresh weight (g), foliage dry weight (g), curd weight (g), curd area (cm2), leaf area (cm2), curd color, vitamin C (mg/g), chlorophyll content (spad meter), total soluble salts (Brix°), yield per plant (kg) and yield per hectare (ton) was recorded and statistically analyzed. It can be concluded that among all the treatments T7 (Mo: 0.1% + Fe: 0.5% + B: 0.5%) showed the best result for all parameters.
