Effect of doses of seaweed-based biostimulant (Equilibrium) on growth indices and economics of rice cultivar PAC 807
Keywords:
Economics, equilibrium, growth analysis, riceAbstract
A field experiment was conducted during kharif 2022 at the Experimental Farm of Department of Agronomy, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur to evaluate the effect of various doses of seaweed ® based biostimulant Equilibrium in rice crop. The experiment was conducted in Randomized Completely Block Design with eleven treatments comprising of single spray (500, 750, 1000 and 1250 ml ha-1) at tillering, two sprays (500, 750, 1000, 1250, 1500 and 2000 ml ha-1) at tillering and boot-leaf stages plus one control (water spray), replicated thrice. Two sprays using 1250 ml ha-1 each at tillering and boot-leaf stage showed at par performance with low dose of 1000 ml ha-1, and was found effective to boost rice growth in terms of plant height (100.4 cm), dry matter accumulation (1039.6 g m-2 ), CGR (16.72 g m-2 day-1 ) and RGR (11.06 mg g-1 day-1) during 60-90 days after transplanting, and thereby leading to maximum returns of Rs 72.7 thousand ha-1.
