Effect of Humic Acid, Boron and Potassium on Growth, Yield and Quality Attributes of Cauliflower
Year: 2024
Type: article
Abstract: Background : Prior research has demonstrated the critical roles that potassium, humic acid and boron play in stimulating plant development, increasing production and affecting the qualitative characteristics of cauliflower.To evaluate the crop's overall performance, more thorough research is still required to clarify the precise impacts and interactions of these nutrients.Methods: An experiment was conducted at the Vegetable Research Farm of Department of Horticulture of Lovely Professional University, Punjab in 2023-24.This study was laid out in a randomized block design in triplicates to analyze the effect of foliar application of humic acid @5mLL -1 , boron @30gL -1 , potassium @1.5gL -1 and their combinations including humic acid @5mLL -1 + boron @30gL -1 and humic acid @5mLL -1 + potassium @1.5gL -1 on different growth [plant height (cm), number of leaves, leaf length (cm), leaf width (cm), chlorophyll index (SPAD value), stem diameter (cm)], yield [days to 50% curd initiation, days to curd maturity, curd weight (g), curd diameter (cm), curd size (cm 2 ), curd compactness (gcm -3 ), curd yield per plot (kg), curd yield per hectare (q) and qualitative traits [total soluble solids ( 0 Brix), vitamin C content (mg per 100 g of fresh weight of curd), dry matter content of leaves (%)and shelf life (days)] of cauliflower at an interval of 40, 50 and 60 days after transplanting.Results : From the obtained results treatment humic acid @5mLL -1 + potassium @1.5gL -1 (T 5 ) showed a significant effect on various growth, yield and qualitative traits.However, some traits like number of leaves, curd compactness (gcm -3 ) and shelf life (days) were found the best with boron @30gL -1 (T 4 ).While, the treatment with humic acid @5mLL -1 + boron @30gL -1 (T 3 ) was found good for the traits including chlorophyll index (SPAD unit).
