Organic fertilizer usage for sweet corn grown on spodosol and ultisol soils

Abstract

Poor soils need to be fertilized for optimum crop production in order to achieve the food security campaigns especially in the developing and underdeveloped countries. This study was aimed at finding the potential benefits of organic fertilization for sweet corn grown two marginal soils (Rhu Tapai or Spodosol and Rasau or Ultisol) as well as the optimum rate of the organic manure that gives the best crop performance. A 5x2x2 factorial experiment using Randomly Complete Block Design (RCBD) was conducted in four replicates at the shade house to find the best organic manure between chicken manure, cattle manure, horse manure, rice husk biochar and the control treatment (without amendment) with or without Arbuscular Mycorrhiza Fungi (AMF) inoculation under two different soil types; Rasau series soil and Rhu Tapai series soil using Thai super sweet corn as a test iv crop
