Abstract

The experiment was carried out in rainy season during 2009 and 2010 at Seed Testing Laboratory of Gochar Mahavidyalaya, Rampur Maniharan, Saharanpur, Uttar Pradesh to study the influence of sowing time and plant geometry on seed quality of okra. Seed collected from all twenty four treatments subjected to laboratory test. In laboratory, experiment was laid out in Complete Randomized Design with three replications. The mean estimates of test weight (67.81g), seedling length (27.96cm.), and seedling dry matter (1.21g) in case of seed harvested from 24th June sowing were significantly best among all the sowing was superior in these traits over rest of the sowing. Very poor performance of these parameters was observed in the crop sown on 22th July. While the standard germination (87.46%), seed viability (83.44%), seed vigour index-I (2243.60) and seed vigour index-II (110.77) was observed superior under the treatment V1 (Prabha Kranti).

Abstract

The present investigation was carried out in rainy season during 2009 and 2010 at Research Farm and Seed Testing Laboratory of Gochar Mahavidyalaya, Rampur Maniharan, Saharanpur, Uttar Pradesh with a view to study the influence of sowing time and plant geometry on plant growth and yield of okra. The experiment was laid out in split-split plot design with three replications and four dates of sowing in each season viz., 10 June, 24 June, 8 July and 22 July 2009 and 2010 taken in main plots and three plant geometries viz., 60 x 30 cm, 60 x 45 cm and 60 x 60 cm in sub plots and two varieties viz., Parbhani Kranti and Pusa A-4 in sub-sub plots. The plant growth and vigour which was evident from greater plant height, pod development, seed size and yield obtained in the crop sown on 10th and 24th June. Seed yield is correlated with the performance of yield contributing attributes and a perusal of data pertaining to seed yield components viz. per cent fruit set, number of pods per plant, pod length, pod thickness, number of seeds per pod revealed that the environment was more favourable for okra seed production when the crop was sown on 10th June and 24th June which were found superior in seed yield and its components over rest of the sowing dates.

Abstract

The field experiment was conducted at Horticulture Research Farm of Choudhary Charan Singh University campus, Meerut U.P. during 2011-12. The nine treatments A₁ (Azotobacter by ischolar_main treatment 0.20g/15 plants), A₂ (Azotobacter by soil treatment 0.40g/plot), G₁ (Gibberellic acid 100 ppm spray at 30 DAT), G₂ (Gibberellic acid 150 ppm spray at 30 DAT), A₁G₁ (Azotobacter by ischolar_main treatment 0.20g/15 plants and gibberellic acid 100 ppm spray at 30 DAT), A₁G₂ (Azotobacter by ischolar_main treatment 0.20g/15 plants and gibberellic acid 150 ppm spray at 30 DAT), A₂G₁(Azotobacter by soil treatment 0.40g/plot and gibberellic acid 100 ppm spray at 30 DAT ), A₂G₂ (Azotobacter by soil treatment 0.40g/plot and gibberellic acid 150 ppm spray at 30 DAT) and A₀G₀ (No Azotobacter and no gibbrellic acid) were evaluated in Randomized Block Design with three replications. The experimental finding revealed that the treatment A₂G₂ (Soil treatment with Azotobacter + spray of GA₃@ 150 ppm) gave the maximum plant height, maximum number of primary branches per plant, maximum number of secondary branches per plant, maximum plant spread, minimum number of days taken for flower bud appearance, maximum number of flowers per plant, maximum flower diameter, maximum fresh weight of flowers per plant and maximum yield of flower in comparison to individual application of GA₃ and Azotobacter.

Abstract

The present investigation was carried out in the orchard situated in District Saharanpur (U.P.) during the years 2010 and 2011 with an aim to improve the quality and shelf life of mango. The treatments were comprised of mulching, borax @ 0.5 and 1.0 per cent, potassium sulphate @ 0.5 and 1.0 per cent, calcium chloride @ 0.5 and 1.0 per cent, calcium nitrate @ 0.5 and 1.0 per cent, GA₃ @ 25ppm and 50 ppm, NAA @ 25ppm and 50 ppm in combination with mulching and water spray without mulching as control. The spray is to be done three times at different times at different stages during the year 2010 and 2011 which is given below-I^st spray on 15^th January (i.e. before flower bud burst), II^nd spray on 15^th February (i.e. at panicle emergence) and III^rd spray on 15^th April (i.e. after fruit set). It may be concluded from the present studies that the application of CaNO₃ improves flowering parameters, increases the number of fruits and fruit yield and K₂SO₄ increase the physical characters of fruit.

Abstract

An experiment involving twenty four genotypes of chilli and three created environments (E₀ – No spray, E₁ – Single spray on NAA @ 40 ppm and E₂ – Double spray of NAA @ 40 ppm) was carried out during spring summer season at Vegetable Research Centre, Pantnagar to determine the best genotype, suitable environment and their interactions for higher production of chilli. Out of the three environments, E₂ was found better for red ripen fruit yield, number of fruits/plant, 100-seed weight, seed : husk ratio, minimum incidence of disease viz., anthracnose and leaf curl virus, whereas, significant variations were observed for all the 18 characters studied. Among genotypes viz., G₂₃ (PC-2062), G₂₄ (PC-2064) and G₂₂ (PC-2057) produced significantly more number of fruits/plant and G₂₀ (PC-7) followed by G₂₁ (PC-56) and G₂ (Co-4) performed better for weight of fruits/plant. Genotypes G₂₃ and G₂₁ produced 110.26 and 71.60 per cent higher yield over check variety Pant C-1, respectively. Longest fruits (13.59 cm) were obtained in G₂₀ (PC-7) .More number and weight of seeds/fruit were recorded in G₂₂ (PC-2057). Out of all the 72 interactions, G₂₃E₁ was found better for number and weight of fruits/ plant whereas, G₂₃E₁ (254.42 q/ha), G₂₂E₁ and G₂E₂ produced higher red ripen fruit yield over rest of the interactions.
