Abstract

A study was conducted to find out the effect of irrigation and fertigation scheduling on growth, flowering, yield and cost economics of guava cv. Lalit elanted under ultra high density planting system. The experiment consisted of 15 treatments combination comprising three different levels of irrigation [50 % (I1), 75% (I2) and 100% (I3) irrigation of pan evaporation] and five level of fertigation [20% (F1), 40% (F2), 60% (F3), 80% (F4) and 100% (F5) or recommended of NPK. Among the different treatment combination, highest shoot gain after pruning (39.90 cm), plant spread N-S (1.72 m), increase in girth of primary branch (0.315 cm) and canopy volume (1.265 m3) were recorded under I3F5 treatment combination. Whereas, highest flowers shoot-1 (47.60), fruit weight (96.91 g), pulp weight (70.84 g), pulp: seed ratio (14.96), number of fruits plant-1 (77.70) and yield (6.75 kg plant-1 & 33.75 t ha-1) were recorded in I2F4 treatment combination. However, treatment combinations I2F4 and I2F3 were found statistically at par with each other in respect of fruit weight, number of fruit plant-1 and yield with each other in all the above parameters. Treatment combination I2F3 gave the maximum net return (Rs. 2,79,081) per ha under ultra high density planting.
