| dc.description | Flowering-fruiting behavior of different mango (Mangifera indica L.) cultivars and their response to agro-chemicals under southern region of Rajasthan Thus, flowering and fruiting behavior significantly and negatively correlated with wind velocity (r = -0.95 & -0.56) and rainfall (r = 0.58 & -0.98) during both the years, respectively. Under these conditions cultivars Langra, Mallika and Bombay Green were promising in terms of fruiting and yield. Among alternate bearing mango cultivars (Dashehari, Langra and Kesar), cultivar Langra recorded higher economic traits like yield (85.92 kg tree-1 & 8.56 t ha-1) and fruit quality (firmness, ascorbic acid and reducing sugar content). Agro-chemicals effect significantly with growth, flowering, yield and fruit quality. Paclobutrazol (1500 ppm) was found better with respect to vegetative growth characters (shoot length & diameter, tree spread, canopy volume and days of fruit set from flower initiation), flowering characters (date of flower initiation, per cent fruit set & retention, days to harvest from fruit set and first flush after fruiting) and yield (yield 86.61 kg tree-1 & 8.66 t ha-1). Interaction between cultivars and agro-chemicals showed significant effect on growth parameters with shoot diameter (0.50 cm) with V3T7 (Kesar + PBZ 500 ppm) and canopy volume (138.13 m3) in V3T9 (Kesar + PBZ 1500 ppm) combination. Flowering-fruiting and yield attributes maximum recorded under combination V2T9 (Langra + PBZ 1500 ppm) with respect to per cent fruit set (1.74%), per cent fruit retention (1.97%), yield per tree (99.29 kg), yield t ha-1 (9.93 t ha-1). As far as economics is concerned highest net return (` 1,87,000) was recorded with V2T9 (Langra + PBZ 1500 ppm) while, returns per rupee investment was maximum in combination V2T7 (Langra + PBZ 500 ppm). Thus, cultivar Langra and agro-chemical paclobutrazol 1500 ppm were better for higher yield and return in mango. | en_US |
| dc.description.abstract | The present investigation entitled “Flowering-fruiting behavior of different mango (Mangifera indica L.) cultivars and their response to agro-chemicals under southern region of Rajasthan” was conducted during two consecutive years 2012-13 and 2013-14 at Agriculture Research Station, Banswara (Maharana Pratap University of Agriculture and Technology, Udaipur). The investigation was conducted with two sets of the experiments. Experiment first selected material was fifteen years old trees of mango cultivars viz., Amrapali, Bombay Green, Chausa, Dashehari, Kesar, Langra and Mallika were taken for the observation of flowering-fruiting behavior and next set of experiment was ‘response of mango cultivars to agro-chemicals’. Second experiment comprised 13 treatments (control – water spray, calcium chloride - 0.3%, 0.6%, 0.9%, potassium nitrate 1%, 2%, 3%, paclobutrazol 500 ppm, 1000 ppm, 1500 ppm and Sorbitol 1.5%, 2.0%, 2.5%) sprayed on three cultivars viz., Dashehari, Langra and Kesar. All the treatments were replicated four times under Randomized Block Design. Result revealed that among seven mango cultivars observed to flowering and fruiting status early flower initiation was occurs in Amrapali and late was recorded under cultivar Chausa. Date of fruit set early was observed in Bombay Green and the late fruit set in Mallika. The highest fruit drop was recorded in cultivar Langra and minimum in Kesar. Early crop in harvest was got in Bombay Green and late in Chausa. The more days taken to maturity was recorded with cultivar Langra as compared to lowest days taken to maturity in Bombay Green. The yield per tree was higher in Langra and the minimum was in Chausa. Maximum heat unit 1799.5 degree days was calculated in cultivar Chausa and minimum was 1305.3 degree days in cultivar Bombay Green. Similarly, heat use efficiency under cultivar Bombay Green (6.28) better followed by Langra (5.35) and Mallika (4.89) over other cultivars. | en_US |
