Effect of nitrogen, phosphorus and potash on growth and yield of second Ratoon golden ROD (Solidago canadensis L.) CV. local under summer season in Saurashtra region

Abstract

An experiment was conducted to study the effect of nitrogen, phosphorus and potash on growth and yield of second ratoon golden rod (Solidago canadensis L.) cv. Local under summer season in Saurashtra region including three factors viz., N (200, 250 and 300 kg/ha), P (50 and 100 kg/ha) and K (25 and 50 kg/ha) and their combinations. Among them, application of nitrogen @ 300 kg/ha, phosphorus @ 100 kg/ha and potash @ 50 kg/ha significantly increase the growth parameters viz., plant height, plant spread, fresh weight of plant, dry weight of plant and number of suckers per plant; and yield attributes viz., number of panicles per plant and number of panicles per hector.
