Effect of application of plant growth regulators on pepper (Piper Nigrum L.)
(Kerala Agricultural University, 1988) Salvi, B R; Desai, A G; Salvi, M J
Different growth regulators whan used in proper concentrations have a promise in increasing the yield of pepper. GA, NAA, 2,4-D (20ppm) and Planofix (100 ppm) seem to be promising in both the methods of application i.e., either by spraying or dipping. Though, application of GA increased the yield significantly batter than the other treatments, its high cost does not permit its economic use. Cost benefit shows that application of plant growth regulators by dipping is rather costly as compared to spraying. Spraying of pepper vines with Planofix at 100 ppm, NAA at 10 ppm and 2,4-D at 20 ppm seems to be more effective in increasing the net return per hectare of pepper cultivation. The additional net returns per hectare over control was recorded by these concentrations are Rs. 4,147; 3,762, and Rs. 3,751, respectively.
