Abstract
The present research work entitled as “Effect of different micronutrients on growth, yield and quality of cauliflower (Brassica oleracea var. botrytis L.) cv. PusaSharad” was studied at Horticulture Research cum Instructional Farm, Department of Vegetable Science, College of Agriculture, IGKV, Raipur (C.G.). The whole experiment was designed for two years, and was carried out for two consecutive rabi seasons during the year 2017-18 and 2018-19.
The experiment was studied with fifteen treatments and three replications with Randomized Block Design. The treatments consisted three different micronutrients such as B, Mo and Zn and its combinations with different concentration and recommended dose of fertilizers viz., T1 - Control (100% RDF), T2 - 100% RDF + Borax @ 20 kg ha-1, T3- 100% RDF + Ammonium molybdate @ 2 kg ha-1, T4 -100% RDF + ZnSO4 @ 25 kg ha-1, T5 - 100% RDF + Borax @ 20 kg ha-1 + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1, T6 – 100% RDF + Ammonium molybdate @ 2 kg ha-1 + Borax @ 20 kg ha-1, T7 – 100% RDF + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1, T8 – 100% RDF + Borax 20 kg ha-1 + ZnSO4 @ 25 kg ha-1, T9 – 75% RDF + Borax @ 20 kg ha-1, T10 – 75% RDF + Ammonium molybdate @ 2 kg ha-1, T11 - 75% RDF + ZnSO4 @ 25 kg ha-1, T12 -75% RDF + Borax @ 20 kg ha-1 + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1, T13 -75% RDF + Ammonium molybdate @ 2 kg ha-1 + Borax @ 20 kg ha-1, T14 -75% RDF + Ammonium molybdate @ 2 kg ha-1 + ZnSO4 @ 25 kg ha-1, T15 - 75% RDF + Borax 20 kg ha-1 + ZnSO4 @ 25 kg ha-1.
To assess the effect of these micronutrients the observations regarding growth parameters [(plant height (cm), number of leaves per plant, stem length (cm), stem diameter (cm), length of leaves (cm), width of leaves (cm), length of root (cm), days to first curd initiation and days of 50% curd maturity)], yield and yield attributing traits [gross curd weight (g), marketable curd weight (g), net curd weight (g), curd diameter (cm), curd yield (kg plot-1) and curd yield (q ha-1], quality parameters [total soluble solids(0Brix), protein content in curd (%) and ascorbic acid content in curd (mg/100g), major nutrient (NPK) and Micronutrient (B, Mo and Zn)] content in soil and plants were recorded. The crop economics was also calculated through estimating the different expenditure and profit {cost of cultivation (Rs ha-1), gross income (Rs ha-1), net income (Rs ha-1), and B: C ratio}. The growth traits were recorded at 30 day after transplanting 45 day after transplanting and at harvest stage while, the yield, quality and nutrient analysis in soil, and plants were recorded at and after harvest.
The obtained experimental results revealed that the combined application of all three micronutrients viz., boron, molybdenum and zinc in various combinations significantly improved the growth parameters [(plant height 63.22 cm during year 2017-18, 61.75 cm during year 2018-19 and 62.49 cm in pooled mean, number of leaves plant-1 22.74 (year 2017-18), 21.96 (year 2018-19) and 22.35 (pooled mean), stem length 12.46 cm (year 2017-18), 11.84 cm (year 2018-19) and 12.15 cm (pooled mean), stem diameter 4.52 cm ( year 2017-18), 4.21 cm (year 2018-19) and 4.37 cm (pooled mean), length of leaves 41.75 cm (year 2017-18), 40.88 cm (year 2108-19) and 41.32 cm (pooled mean), width of leaves 22.77 cm (year 2017-18) 21.87 cm (year 2018-19) and 22.32 cm (pooled mean), length of root 23.67 cm (year 2017-18), 22.36 cm (year 2018-19) and 23.01 cm (pooled mean), days to first curd initiation 43.75 days (year 2017-18), 45.14 days (year 2018-19) and 44.45 days (pooled mean) and days of 50% curd maturity 60.27 days (year 2017-18), 61.44 days (year 2018) year and 60.86 days pooled mean)] yield and yield attributes (curd yield 293.25 q ha-1 during year 2017-18, 268.75 q ha-1 during year 2018-19 and 281.00 q ha-1 during pooled mean), quality parameters, nutrient content in soil and plant analysis and B: C ratio 2.26, 2.38 and 2.32 during year 2017-17, year 2018-19 and pooled mean basis. Furthermore, among the various combination, the application with treatment T5 - 100% RDF + boron @ 20 kg ha-1 + molybdenum @ 2 kg ha-1 + zinc @ 25 kg ha-1 was reported as the most promising combination in improving the growth, yield and yield attributing, quality and nutrient content in soil as well as in plant when compare to control T1 - (100% RDF) during both the years and pooled mean basis.
It is evident from the present investigation that the application of micronutrients is beneficial in enhancing and improving the growth, yield, and quality aspects of cauliflower and could be used in the climate of the Chhattisgarh region.
