Impact of boron, urea and GA3 on the soluble protein content of Broccoli

Abstract

Broccoli (Brassica oleracea var. italica), an Italian vegetable which belongs mainly to Mediterranean region, is becoming popular day by day in India. Owing to its great taste and nutritive value, it is fastly becoming a choice in cities. The proteins are building blocks of the body and an important constituent of various enzymes and hormones. Boron is one of the most important micronutrient essential for plants. Urea on the other hand,is the major nutrient required for plants and main source of nitrogen which is an important constituent of various proteins.GA3 is the most widely used plant growth regulator. In light of above facts an investigation was carried out at the Horticulture Farm, Birsa Agricultural University, Ranchi, Jharkhand. The experiment consisted of sixteen treatments with three replications in Randomized Block Design. The content of total soluble content of protein was estimated spectrophotometrically using Lowry’s method. The result showed that foliar application of treatment having [email protected]% with GA3@75ppm had recorded the maximum protein content of 9.53 mg/100g, which was significantly at par with treatment having [email protected]% with GA3@50 ppm which recorded the value of 9.40mg/100g and treatment having [email protected]% which recorded the value of 9.26mg/100g in the year 2014-15. These three treatments remained statistically at par also in the year 2013-14.
