Abstract
Sprouting broccoli (Brasica oleracea var. Italica) is one of the most nutritious cole crop. Although
broccoli is not so popular yet in Jharkhand, it is slowly gaining popularity during the last few years among
the consumers. It is gaining importance due to its nutritional value including flavour, taste, carotenoids and
anticancerous properties. Among the entire cole family, broccoli is rated as most remunerative. It has
tremendous production capability and its production and productivity can be increased further by applying
foliar spray of plant nutrient and GA3.
The role of mineral nutrients and plant growth regulators in various physiological and biochemical
processes in plant to regulate growth and yield is established. Beside this, the beneficial effect of applying
foliar plant nutrients and plant growth regulators, expressed as an increase in yield and improvement of
crop quality has been noted in many vegetables species.
The present investigation entitled, “Studies on the Effect of Boron, Urea and GA3 on Growth,
Yield and Quality of Broccoli (Brassica oleracea var italica)”, on cv. Fiesta was carried out during winter
seasons in the consecutive years 2013-14 and 2014-15 at Vegetable section of Horticulture garden under
faculty of Agriculture, Birsa Agricultural University, Ranchi, (Jharkhand). The experiment consisted of 16
treatments replicated thrice was laid out in Randomized block design. The foliar nutrients and plant growth
regulators used were Boron, Urea and GA3 at different concentrations, individually as well as in different
combinations. The spraying was done twice at 20 and 40 days after transplanting.
During the course of investigation, it was observed that nutrients and plant growth regulators
showed remarkable influence in vegetative growth, curd initiation, curd production, yield, quality and Shelf
life. Thus on the basis of experimental findings it may be safely concluded that broccoli cultivar Fiesta when
treated with urea @ 1.0% with GA3 @ 50ppm spray resulted higher yield and profit per hectare. However
the urea @ 1.5% along with GA3 @ 75ppm in combination, had shown the impressive vegetative growth. In
case of earliness in curd maturity, the urea @ 0.5% in combination with GA3 @ 75ppm plus B as Borax @
(2%) had shown the most favourable effect. Among various quality parameters, the treatment T15 having the
combination of Urea @ 0.5% + GA3 @ 75ppm + B as Borax @ 2% had shown quite impressive results.
However, the spray of GA3 @ 75ppm has favourable effect in enhancing the Shelf Life of curd at ambient
condition.
