Abstract :
A field experiment was conducted to find out most appropriate combination of bio-fertilizers and chemical fertilizers for
mango production during 2011 - 13 at the Horticultural Research Farm, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand. The trial was laid out inRandomized BlockDesign, replicated thrice, with thirteen treatments including control. It was found that the application of 100% N + 85% P2O5+ Azotobacter + PSB (T6) significantly increased tree height (m) at initial and harvesting stage, tree spread N- S (m) at initial and harvesting stage and canopy volume (m3) at initial stage, whereas tree spread E - W at harvesting stage and canopy volume (m3) at harvesting stage was found superior with 100% N + 100% P2O5+ Azotobacter + PSB (T4). The application of 85% N + 85% P2O5+ Azotobacter + PSB (T10) appeared as the most suited combination for providing maximum number of panicles per branch, length of panicle (cm), number of flowers per panicle, sex ratio, total chlorophyll content of leaf (mg/g) at 50 per cent flowering and before harvesting, leaf area (cm2) at 50 per cent flowering and before harvesting, marketable fruit weight (g), number of fruits per tree and fruit yield (kg/tree). Shelf- life (days) and fruit volume (cc) significantly increased with 70% N + 85% P2O5+ Azotobacter + PSB (T13). Tree spread E - W at initial stage was found non- significant. Treatment 85% N + 85% P2O5+ Azotobacter + PSB proved as the next better treatment followed by 100% RDF.
