ThesisItem Open Access EFFECT OF FOLIAR SPRAY OF PLANT GROWTH REGULATORS ON GROWTH, YIELD AND QUALITY OF CAULIFLOWER (Brassica oleracea var. botrytis L.) CV. PANT SHUBHRA(Indira Gandhi Krishi Vishwavidyalaya, Raipur, 2019) Sahu, Tikesh Kumar; Dixit, Amit; Sharma, Praveen Kumar; Tiwari, Alok KumarThe present investigation entitled “Effect of foliar spray of plant growth regulators on the growth, yield and quality of cauliflower (Brassica oleracea var. botrytis L.) cv. Pant Shubhra” was carried out in Research cum instructional farm Department of Vegetable Science, COA, IGKV, Raipur (C.G) during 2018-19. The experiment was carried out with RBD with 10 treatments and 3 replications. All treatments exhibited superior growth, yield and quality of curd. Treatment T2 found highly effective for growth parameter as it showed greatest plant height (61.80 cm), no. of leaves per plant (23.80), stem length (20.40 cm) and leaf length (45 cm) while the treatments T10, T8 and T6 recorded highest stem diameter (10 cm), leaf width (31.33 cm) and root length (24.40 cm), respectively. The treatment T6 found highly effective for yield attributing characters as it recorded highest curd diameter (46.20 cm), curd weight (468 gm), per plot yield (6.55 kg) and per hectare yield (173.33 quintal) while the treatment T9 showed second position respectively. Recorded highest TSS in treatment T6 (6.56 0Brix) followed by T7 (5.96 0Brix), T8 (5.7 0Brix) and T10 (5.52 0Brix). Recorded highest protein content in treatments T6 (8.89%) followed by T7 (8.41%), T10 (8.37%) and T2 (8.34%). Therefore the treatments T6, T2, T8, and T9 found highly effective as it improves vegetative growth, yield and quality of crop.ThesisItem Open Access EFFECT OF FOLIAR SPRAY OF PLANT GROWTH REGULATORS ON GROWTH, YIELD AND QUALITY OF CAULIFLOWER (Brassica oleracea var. botrytis L.)

The experiment was laid out in randomized block design (RBD) with three replications. The treatment comprised nutrient combination of T1 - 50% RDF as basal + 50% RDF through Fertigation at flowering, T2 - 50% RDF as basal + 50% RDF through Fertigaion at pod initiation, T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, T4 - 100% RDF as basal + Irrigation at flowering, T5 - 100% RDF as basal + Irrigation at pod initiation, T6 - 100% RDF as basal + Irrigation at grain filling, T7 -100% RDF as basal. The soil of the experimental field was clayey in texture (Vertisols) with low N, medium P and high K content. Growth parameters like Plant height, number of leaves and dry matter accumulation, number of branches per plant, crop growth rate and relative growth rate were maximum under treatments T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling and minimum was under T7 - 100% RDF as basal. Yield and yield parameters like number of pods per plant, number of seeds per pod, number of seeds per plant, rain fall use efficiency, seed and stover yield were maximum recorded under the treatments T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, minimum was under T7 - 100% RDF as basal. Higher N, P, K, uptake by plant was recorded under the T3 - 50% RDF as basal + 50% RDF through fertigation at grain filling, as a compared to other treatments of fertigation and the lowest N, P, and K uptake by plant was recorded under T7 - 100% RDF as basal. Economics of soybean production in terms maximum gross return (Rs. 84708 ha-l), net return (Rs.64756 ha-l) and benefit: cost ratio (3.25) was recorded under T3 - 50% RDF as basal +50% RDF through fertigation at grain filling in soybean.
