Abstract:
An experiment was conducted at Instructional farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat, India during 2018-2019 to study the effect of pre-harvest sprays on fruit yield and associated traits in sapota cv. Kalipatti. The experiment was laid out in a Completely Randomized Design comprising of six treatments namely T₁- Control, T₂- GA₃ 100 ppm, T₃- Novel 1%, T₄- Ca(NO₃)₂ 5000 ppm, T₅- CaCl₂ 5000 ppm and T₆- Potassium silicate 4 ml/l. Sapota trees were sprayed in the months of January, May and October during 2018 and 2019 and each treatment was repeated thrice. Experimental results indicated that pre-harvest spray of GA₃ at 100 ppm recorded significantly the maximum fruit weight (83.11, 85.24 and 84.17 g), fruit volume (78.07, 80.06 and 79.06 cc) and fruit yield [(163.86, 171.22 and 167.54 kg/tree) and (16.39, 17.12 and 16.75 t/ha)] during 2018, 2019 and in pooled data, respectively.
