Abstract

A field experiment was conducted to assess the effect of different chemicals, soil application of paclobutrazol and combined application of paclobutrazol with chemicals as foliar spray on flowering physiology and yield in mango cv. Imam Pasand at Department of Fruit Crops, Horticultural College and Research Institute, Periyakulam during the period between 2011 and 2012. The experiment was laid out with sixteen treatments and two replication in a Randomized Block Design. The soil application of paclobutrazol @ 0.75.a.i. m-2 of tree canopy diameter during September month along with foliar spray of KNO3 @ 1 per cent twice during October and November at 20 days interval was very effective in physiological parameters, soil application of paclobutrazol along with KNO3 foliar spray increased leaf nitrogen (1.75 %), phosphorus (0.16 %) and potassium (0.86 %). The same treatment registered the lowest gibberellic acid (1.39 µg g-1). In both the treatments viz., foliar spray of KNO3 combined with soil application of paclobutrazol @ 0.75.a.i. m-2 of tree canopy diameter and application of paclobutrazol alone were recorded the highest yield characters viz., panicle length (34 cm & 33.63 cm), hermaphrodite flowers (12.62 % and 12.58 %) and fruit yield (33.50 kg tree-1 and 31.40 kg tree-1) respectively are on par and statistically significant.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
