Effect of Vermicompost Using Different Leguminous Crops as Nitrogen Source on the Performance of Ratooned Kangkong

Abstract

The study was conducted at Organic Agriculture Project of CapSU Burias, Mambusao, Capiz to determine the effect of vermicompost from different plant sources with three ratoons using RCBD with three replications. The treatments used were: Treatment B1 – Azolla, Treatment B2– Trichantera, Treatment B3– Kakawate, and Treatment B4– Mixed (Azolla, Trichantera, and Kakawate). The data were subjected to Analysis of Variance using STAR software and LSD for mean comparisons.

The study revealed that among growth and yield of kangkong only the width of widest leaf, weight of marketable plant, and number of marketable plant were affected by the application of vermicompost with different leguminous crops as N source. Tricanthera and mixed leguminous crops as source of N in vermicompost when applied to kangkong gave the best result in the mentioned parameters. Likewise, the number of ratooning affected all the growth and yield parameters. Kangkong when for the second time up to the third time gave heaviest and most number of marketable plants. The total number of pest that infested the kangkong was not influenced by the application of vermicompost with different leguminous crops as source of N. Kangkong applied with vermicompost with trichantera as N source gave the highest net profit (Php 1488.80), and the lowest net profit was obtained from the kangkong applied with vermicompost with kakawate as N source (Php 749.00). Leguminous crops can be used in vermicomposting as N source and can be applied to rationed kangkong.
