Seeds of marigold cv. ‘Pusa Narangi Gainda’ were treated with different gamma irradiation treatments viz, control, 25 Gy, 50 Gy, 75 Gy, 100 Gy, 125 Gy and 150 Gy and evaluated for various morphological characters. Reduction in survival percentage, plant height, number of branches and plant spread was observed after irradiation and with increase in exposure of gamma rays. Early flower bud initiation and flower opening was observed in lower dose of gamma rays. Flower diameter, number of flowers and length of peduncle was significantly highest at the lowest dose of gamma irradiation. The stimulatory effect of gamma irradiation was observed at 25 Gy in almost all the characters, though the intensity of inhibition increased with increasing exposures of gamma rays. On the basis of present observation, it may be concluded that irradiation of gamma rays of 25 Gy was found to be beneficial for growth and flowering characters in African marigold cv. Pusa Narangi Gainda

An investigation was carried out to evaluate the growth and the flowering of some of the commercial annual flower crops as intercrop in coconut ecosystem. Commercial annual flower crops viz., African marigold, French marigold, celosia, gomphrena and China aster were grown as an intercrop in coconut plantation and also under open condition for comparison. The results of the experiment showed that all of the crops performed to its optimum in the coconut shade, but less well than the open condition. The parameters viz., Plant height, internodal length, number of lateral branches, days taken for first flowering, flower diameter and yield were recorded. The yield was relatively higher in the open condition. The morphological characters were higher in the open condition and the earliness to flower bud initiation and flowering were observed in the open condition.

A field experiment was conducted to study the response of nitrogen and GA3 on growth and flowering behavior of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda at the Horticultural Research Farm, Department of Horticulture C. C. S. University Campus, Meerut (U.P.) in 2015. There were applied a total number of nine treatments and layout arranged in randomized block design (RBD) with three replications. Result indicated that soil application of nitrogen@100kg/ha with foliar application of GA3 @ 200ppm at 20 and 50 days after transplanting were found to be statistically significant and most beneficial in relation to plant height, primary branch, secondary branch, spread of plant, diameter in stem, flower diameter, number of flower per plant, fresh weight of flower per plant and yield of flower as compared to control and other treatments.

This experiment was conducted to study the effect two types of biochar and nitrogen fertilizers amendment, with different rates on morphological attributed of garland chrysanthemum plant. Two different types of biochar (BT) Eucalyptus biochar (EB), and Salix biochar (SB), four biochar rates- BR (at 0, 1, 2 and 3%), and three rates of nitrogen fertilizer- NR (0, 140 and 280 mg kg-1) with three replications on plant growth were used in this research. The (Chrysanthemum coronarium L.) was used as a test plant to study some morphological characters including: Plant Height (PH) cm, Fresh Weight Per Plant (FWP) g, Number of Leaves Per Plant (NLP), Stem Diameter (SD) cm, Flower Diameter (FD), Number of Flower Per Plant (NFP) and Number of Flower Bud Per Plant (NFBP) cm. The Double Barrel Design was used for making biochar by pyrolysis system. The experiment was conducted in the plastic house condition. The results showed that biochar applications at a rate of 3%, significantly increase PH, FWP, NLP, SD, FD, and NFBP, while NFP increased only at 2% biochar application and decrease at the 3% rate. The application of 280 mg kg-1 of nitrogen significantly increased all of the parameters. The plant grown in the soils amended with the EB were higher than grown in the soils of the SB. In addition, the best value in the study was observed were biochar combined with nitrogen fertilizers.

The present investigation entitled “Effect of Integrated nutrient management (INM) on Plant growth, Flower yield and shelf life of African Marigold (Tagetes erecta L.) c.v. Pusa basanti” , was under taken at department of horticulture, during the year 2013-14. The experiment was laid out in randomized block design with 13 treatments replicated thrice. The treatments comprised of FYM, vermicompost, poultry manure and bio- fertilizer (Azotobacter) with 25% RDF, 50% RDF and 75% RDF in different combinations including control (RDF). The results revealed that application of 75% RDF + 25% vermicompost (T2) produced significantly maximum plant height (76.77 cm), number of primary and secondary branches per plant (19.40, 33.47 respectively), number of leaves per plant (209.6), earliest in days to first flower bud initiation (50.07), days to first flowering (58.07) and days to 50% per cent flowering (62.87), Also number of flowers per plant (44.07), flower diameter (6.96 cm), flowering duration (54 days), average flower weight (8.52 g), flower yield per plant (375.42 g) and flower yield per plot (3.51 kg), flower yield per hectare (16.65 t) as compared to control and with application of 50% RDF + 50% vermicompost (T6) showed maximum shelf life (6.70 days) of flowers at room temperature. Economic point of view treatment T2 was found to be most economically viable in terms of gross return, net return and benefit cost ratio (2.52:1).

An experiment was carried out to access the effect of different doses of Cycocel and Maleic hydrazide on growth and flowering of African marigold (Tagetes erecta L.) cv. Pusa narangi gainda at Horticultural Research Center (HRC) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut, Uttar Pradesh during the year 2019-2020. The investigation was laid out in Randomized Block Design (RBD) with nine treatments and three replications. The results indicated that among the treatments, minimum plant height with the application of MH 250 ppm (57.03 cm), plant spread of east to west (45.17 cm), plant spread north to south (46.40 cm), the number  of branches per plant (37.61), Days taken to first flower bud initiation (54.60 days), days has taken to opening of first flower (67.21 days), days have taken to opening of 50% flowering (83.72 days), duration of flowering (78.22 days), The study revealed that the number of branches and flowering duration significant higher than control and other treatment the height of plant also decrease.

The present study was conducted at experimental orchard of Department of Horticulture, CCS Haryana Agricultural University, Hisar (Haryana), India with a view to optimize pinching time and spacing in African marigold for achieving better growth, flowering and yield. Design of the experiment was factorial Randomized Block Design with three replications. Experiment comprises of two levels of pinching (no pinching & pinching at 28 DAT i.e. Days After Transplanting) and three levels of spacing (40 x 40 cm, 40 x 30 cm & 30 x 30 cm) in all possible combinations. Maximum number of branches/plant (12.11), plant spread (63.59 cm), fresh weight of plant (358.79 g), number of buds/plant, duration of flowering (53.95 days), number of flowers/plant (54.54), stalk length and flower yield/plant (403.68 g) and flower yield/hectare (33.33 t) were significantly recorded in plants pinched at 28 DAT at 5% level of significance, whereas, maximum plant height (73.52 cm), flower diameter (6.38 cm), fresh weight of flower (8.93 g) was obtained in un-pinched plants. In case of spacing, maximum plant spread (64.01 cm), primary branches/plant (11.42), fresh weight of plant (370.20 g), number of buds/plant, number of flowers/plant (51.43), duration of flowering (53.98 days), flower diameter (6.42 cm), fresh weight of flower (9.03 g), flower yield/plant (460.42 g) was recorded at 40 x 40 cm, whereas, maximum plant height (71.76 cm), stalk length, flower yield/hectare (36.34 t) was observed with 30 x 30 cm. Results revealed that plants pinched at 28 DAT with widest spacing (40 x 40 cm) were found best for better growth, flowering and yield of African marigold.
