Abstract:

The investigation was conducted at Department of Horticulture College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra during the year 2015-16 and 2016-17 to assess the effect of foliar nutrition on post monsoon vegetative flush and flowering in mango cv. Alphonso. The experiment was laid out in Randomized Block Design with three replications and seven treatments viz; Urea-1% , Potassium nitrate - 1%, Orthophosphoric acid- 0.1%, Urea-3% , Potassium nitrate - 3%, Orthophosphoric acid- 0.2% and control (No spray). Two sprays were taken in each treatment. 1st spray immediately after emergences of new vegetative flush and second 15 days after first spray. The organic carbon content (in shoot), shoot nitrogen content and C : N ratio were analyzed at three stages i.e. one month before flowering, during flowering and at one month after flowering by standard methods. One month before flowering, KNO3 3% (T5) treatment recorded significantly highest shoot carbon content (18.40 per cent), urea 3% (T4) treatment recorded significantly highest shoot nitrogen content (1.457 per cent) and KNO3 (T5) treatment recorded significantly highest C : N ratio (13.35). During flowering, highest shoot carbon content (13.13 per cent) was in KNO3 3% (T5), shoot nitrogen content (1.246 per cent) was maximum in urea 3% (T4) and highest C : N ratio (10.63) was in KNO3 3% (T5). At one month after flowering, the significantly highest shoot carbon content (15.33 per cent) was recorded in KNO3 3% (T5) treatment, highest shoot nitrogen content (1.135 per cent) was in urea 3% (T4) treatment and highest C : N ratio (10.63) was recorded in KNO3 3% (T5) treatment.
