Effect of biostimulants on economics of flower and seed production in china aster cv. Kamini

Abstract

The present experiment was conducted at the Department of Horticulture, College of Agriculture, Shivamogga (under University of Agricultural and Horticultural Sciences, Shivamogga) during 2016-17 to determine the effect of biostimulants on yield and economics of China aster cv. Kamini. The experiment comprised of thirteen treatments viz., two concentrations of biostimulants at four frequencies (first, second, third and fourth spray at 45, 60, 75, 90 days after transplanting) and control. Each treatment was replicated thrice in randomized complete block design (RCBD). The maximum flower yield/ha (30.23t) and seed yield/ha (4.57q) was obtained from the plants treated with GA3 @ 200ppm. The study on the economics revealed that, GA3 @ 200ppm recorded the highest B: C ratio of 6.1 and 12.08 for flower and seed production, respectively.
