The experiment entitled "Effect of gibberellic acid and naphthalene acetic acid on growth yield and quality of chilli (Capsicum annum L.)” was conducted at Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj during August to December, 2021. Experiment was laid out in Factorial Randomized Block Design with three replications and ten treatment combinations. The experiment consisted of two factors. Factor A: Variety (two variety) as TMPH-449, TMPH-443 and Factor B: Plant growth regulator T1: NAA (30ppm) T2: NAA (40ppm) T3: GA3 (50ppm) T4: GA3 (100ppm). The results revealed that among the varieties studied, variety TMPH-449 resulted better in vegetative growth (Plant height, leaf area) whereas variety TMPH-443 resulted better in vegetative growth (Number of branches per plant), yield parameter (Minimum days taken for 50 percent flowering, minimum days to first harvest, length of fruit, fruit girth, weight of fruit, number of chilli fruit per plant, average fruit yield per plant, fruit yield per hectare), and quality parameter (total soluble solids). Among different concentrations of growth regulator application T2: NAA (40ppm) gave better result in vegetative growth (Plant height, Number of branches per plan, leaf area), yield parameter (Minimum days taken for 50 percent flowering, minimum days to first harvest, length of fruit, fruit girth, weight of fruit, number of chilli fruit per plant, average fruit yield per plant, fruit yield per hectare), and quality parameter (total soluble solids). The best interaction amount different variety and growth regulators were found to be variety TMPH-443 and Growth regulator T2: NAA (40ppm) which give maximum growth and quality characteristics of chilli.
A field experiment entitled “Intercropping of Radish and Beetroot with Chilli under Prayagraj Agro-climatic conditions” was conducted from August, 2021 to February, 2022 at the Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was laid out in Randomized Block Design (RBD) with three replications and 12 treatments. The experiment consisted of six cropping combinations viz., sole chilli, sole radish, sole beetroot, chilli + radish, chilli+ beetroot, chilli + radish + beetroot. The highest yield (green chilli) was obtained from treatment T1 (sole chilli @ 100 % RDN) (13.09 t ha-1). Among the intercropping treatments, the highest chilli yield (12.62 t ha-1) was obtained from treatment T10 (chilli @ 50% RDN + radish @ 50% RDN) whereas the lowest (9.45 t ha-1) was found in treatment T6 (chilli @ 75% RDN + radish @ 12.5% RDN + beetroot @ 12.5% RDN). Intercropping reduced chilli yield but total chilli with intercrop yield increased over sole chilli due to the contribution of companion crops. The highest chilli along with intercrop yield (150.71 t ha-1), gross return (1101506 Rs. ha-1), net return (817969 Rs. ha-1) and benefit cost ratio (3.88) were obtained from treatment T12 (chilli @ 50% RDN + radish @ 25% RDN + beetroot @ 25% RDN). Considering the experimental findings, treatment T12 (chilli @ 50% RDN + radish @ 25% RDN + beetroot @ 25% RDN) found the most suitable combination for higher productivity and economic return under Prayagraj agro-climatic conditions.
The experiment was conducted in the Department of Horticulture, Sam Higginbottom University of Agriculture Technology and Science, Prayagraj, during 2021-2022. The experiment was laid out in Completely Randomized Design (CRD) with 7 hybrids and each hybrid was replicated 3 times. The different hybrids used in the experiment were npy x Golden Crown x Black Hawk, Maung x Red Bracelet, Maung x Black mkmk, Black Hawk, Red Bracelet x Big Flower x Black Hawk, Bb x Black Chadda Petch, Bb(F1) x npy Golden Crown x Black Hawk. The result obtained showed that the hybrid Black Hawk showed significantly better performance in parameters like germination percentage (86 %), seed vigour index (610), seed viability (0.86), germination speed index (1.37), survival percentage (80 %), seedling height, (8.5 cm), no. of leaves per seedlings (12), estimated leaf area (4 sq.cm), stem/caudex diameter (1.56 cm) and taproot length (6.2 cm), which was par with the hybrid npy x Golden Crown x Black Hawk.
An experiment entitled Influence of organic manures on growth, flowering, quality and yield of carnation (Dianthus caryophyllus) cv. Master under naturally ventilated polyhouse conditions of Prayagraj was conducted in naturally ventilated polyhouse of Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj, during November, 2022 to April, 2023 with an aim to identify the most suitable organic manure combination under the agroclimatic conditions of Prayagraj. There were thirteen treatments replicated thrice in Randomized Block Design (RBD). It was observed that treatment T11 (RDN + FYM 2.5kg/m2 + Vermicompost 1.25kg/m2 + Neem cake 1kg/m2 ) was significantly better in all the parameters studied like plant height (48.5 cm), number of primary branches (7.6), days taken to first bud initiation (93.5), flower diameter (6.3 cm), flower stalk length (77.2 cm), vase life (6.2 days), number of cut flowers per plant (5.6), number of cut flowers per 200 square meter (27,833.3).
