IMPACT OF INTEGRATED SOIL FERTILITY MANAGEMENT AND SOWING DATE ON GROWTH, YIELD AND DIGESTIVE ENZYMES IN RADISH

Abstract

Study to assess the impact of integrated soil fertility management in Radish (cv. Early Long White) was conducted in Rabi Season 2020-21 at experimental field of Southern Zone Agricultural Research Center, Pakistan Agricultural Research Council University of Karachi (24.0 oN latitude and 67.0 oE longitude). Seed was sown with two sowing dates viz. 1st and 15th October. Soils of trial area were sandy in texture, alkaline in reaction (pH 9.74) and saline in nature with (EC dSm-1>4.0). Treatment TI: 100% NP at 135Kg N; 90 Kg P, T2: NP: Organic liquid fertilizer (50:50 %) and T3: 100% organic liquid fertilizer (45ml) was applied accordingly. It was observed that radish sown on 15th October, growth and yield attributes viz: plant height (cm), leaves plant-1, weight of leaves plant-1, root length (cm), root girth (cm), root weight (g), plant biomass (g), and root yield (g) and digestive enzymes content shown to have significantly increased upon integration of inorganic fertilizer (NP) with organic liquid fertilizers. It is concluded that by improving soil physicochemical and biological properties, growth, yield, amylase and protease contents in radish may also be enhanced
