Estimation of benefit/cost ratio of various plant growth regulators in phalsa (Grewia subinequalis DC)

The present investigation entitled “Estimation of benefit/cost ratio of various plant growth regulators in phalsa (Grewia subinaequalis D.C.)” was conducted at the Main Experiment Station, Horticulture, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad, Uttar Pradesh during 2014-2015 in randomized block design and replication of three and ten treatments T₁ – control (water spray), T₂ – GA₃ 50 ppm, T₃ – GA₃ 100 ppm, T₄ – GA₃ 150 ppm, T₅ – NAA 50 ppm, T₆ – NAA 100 ppm, T₇ – NAA 150 ppm, T₈ – ethrel 50 ppm, T₉ – ethrel 100 ppm, T₁₀ – ethrel 150 ppm.
GA₃ at 150 ppm fetches highest gross income, net return and benefit:cost ratio was found, however, NAA 150 ppm GA₃ 100 ppm and ethrel 100 ppm also significantly increased the income and benefit/cost ratio.
Foliar application of GA₃ at 150 ppm was effective in increasing vegetative growth, yield and quality parameter, respectively, and ethrel at 100 ppm was found best in improvement of sugar content in phalsa fruits.
All plant growth regulators significantly improved yield and higher benefit:cost ratio over the control.
