Study on effect of integrated nutrient management on growth and yield of cauliflower (Brassica oleracea var. botrytis L.)

Abstract

In order to investigate the effect of integrated nutrient management on growth and yield components in Cauliflower, Brassica oleracea var. botrytis L., cv. Pusa snowball- 16, an experiment was conducted using Randomized Block Design with two replications. The experiment comprised of 14 different treatment combinations comprising of different sources of nutrients including organic, inorganic and bio-fertilizers. The growth parameters like height of plant (12.10, 23.50 cm), number of leaves per plant (9.10, 14.40) and diameter of stem (1.20, 2.10 cm) at 40 and 60 DAT respectively, the days required for curd initiation (62.00 days), days required for curd maturity (85.70 days) and staying period of curd (9.50 days) were observed maximum in treatment combination 75 % RDF + FYM + Azotobacter + Azospirillum (T6). The yield parameters like weight of curd per plot (17.50 kg/plot) and yield per hectare (180.04 q/ha) which was increased 44.10 per cent over RDF. From the studies it can be inferred that the application of 75 % RDF + FYM along with Azospirillum and Azotobactor was found to be the most effective treatment combination for getting enhanced growth and yield in cauliflower.

Effect of integrated nutrient management on the growth and nutrient content of chilli (Capsicum annuum L.)

“…Application of inorganic fertilizers alone failed to produce maximum nitrogen content of plant and fruit. The similar findings were reported by Rohit Pawar and Barkule (2017) [11] .…”

Effect on soil health of cauliflower (Brassica oleracea var. botrytis) cultivation with Integrated Nutrient Management

“…It is widely cultivated all over the world for its special nutritive values, high productivity and wider adaptability under different ecological conditions. The cauliflower crop of Brassica family is a heavy feeder of mineral elements; it removes a large amount of macronutrients from the soiland for that Heavy manuring has been recommended for getting a good yield of cauliflower by different workers in India (Pawar and Barkule, 2017). Mineral nutrition does play an important role in influencing the quality of crops and it is fact that the soil health deteriorates due to continuous use of chemical fertilizers, (Savci, 2012).…”

Effect of Bio-NPK and Organic Manures on Growth, Yield and Economics of Cauliflower (Brassica oleracea var. botrytis l.) var. Pusa Snowball K 1

“…The number of leaves was much higher in seedlings dipping with Bio-NPK for 20 minutes, which might have triggered an increase in the biological nitrogen fixation and availability of phosphorus required for vigorous vegetative growth. Consequently, it finally results in the growth of more leaves [8] . And also found maximum in 100 % nitrogen through vermicompost, which showed better result than other organic manures due to larger soil availability of both naturally occurring and added nutrients resulted to increased vegetative growth and leaves of cauliflower plant.…”
