Effect of Boron on Growth and Yield Parameters of Cauliflower (Brassica oleracea var botrytis cv Snow Mystique) in Terhathum, Nepal

Abstract

A study was conducted to determine the effect of different levels of boron on growth and yield parameters of Snow Mystique variety of cauliflower at farmer's field in Myanglung, Terhathum, Nepal during the winter season of 2019 AD. Five levels of boron viz, control (0 kg/ha), 0.5 kg/ha, 1.0 kg/ha, 1.5 kg/ha, and 2.1 kg/ha were applied in the field that was laid out in Randomized Complete Block Design (RCBD) with four replications. Data were recorded regarding plant height, canopy cover, and leaf number at 30, 45, 60, and 75 days after transplanting while yield parameters like curd diameter, curd yield, and biological yield after harvest. Days to curd initiation, days to harvest, and incidence of hollowing were also recorded in this study. Results revealed that boron had significant effect on growth as well as yield parameters of cauliflower, where the value of these parameters were higher at higher boron dose. Boron at the rate of 2.1 kg/ha produced significantly higher curd yield (67.59 t/ha), curd diameter (25.21 cm) and biological yield (72.27 t/ha) whereas the value of these parameters were lowest with control. Similarly, boron had significant effect on incidence of hollowing where the application of boron at the rate of 2.1 kg/ha recorded the minimum incidence of hollowing (15.27 %). Results from this experiment concludes that application of boron at the rate of 2.1 kg/ha could be suggested for cauliflower growing farmers of Terhathum district for increased growth and yield of cauliflower.

Effect of boron and molybdenum on growth and yield attributes of cauliflower (Brassica oleraceae Var. Botrytis L) at Salyan, Nepal

“…The correlation between increasing boron dosage and leaf number is corroborated by Kamal et al (2013), indicating that boron significantly boosts leaf count in cauliflower. Enhanced nutrient uptake, photosynthesis, and heightened metabolic activity in plants due to boron may account for the observed increase in leaf number (Poudel et al, 2022). Moreover, boron as a micronutrient has been shown to effectively increase leaf number in cauliflower (Moklikar et al, 2018).…”

“…Further, iron is associated with regulating CO 2 uptake in plants and enhanced photosynthesis resulting in the accumulation of carbohydrates and better plant growth (Yoon et al, 2019). Boron is an important nutrient for cell wall for-mation and inducing cell differentiation leading to shoot growth and development of leaf primordia which could be associated with the enhancement of nutrient uptake, photosynthesis, and higher metabolic activity (Poudel et al, 2022). The combined application nano-Zn and B in N 1 M 2 (nano-Zn and borax @ 1000 ppm each) increased the leaf number per plant (21.75, 33.17 and 38.17, respectively) at 45, 60 and 75 days after transplanting and was at par with N 1 M 1 (nano-Zn and CuSO 4 @ 1000 ppm each) (21.08, 31.33 and 36.67, respectively) which could be due to synergistic impact of boron in combination with nano-Zn.…”
