Growth and Seed Yield of Cowpea (Vigna unguiculata L.) and Rice Bean (Vigna umbellata) Accessions Applied with Different Organic-Based Fertilizers under Mangaldan, Pangasinan Condition

Abstract

The study was conducted from November 2015 to May 2016 at Barangay Salaan, Mangaldan, Pangasinan to identify the best accessions of cowpea and rice bean; to identify the best organic fertilizer applied on different cowpea and rice bean accessions; to identify the interaction between cowpea and rice bean accessions and organic-based fertilizers; and to determine the profitability of growing cowpea and rice bean applied with organic-based fertilizers. Cowpea accession CP-2013-015 produced the highest total seed yield, had low infestation of pod borer and high resistance to bean rust. Either Siglat or Polar Mix may be applied; however, higher ROCE resulted from the cultivation of CP-2013-015 applied with Siglat. Rice bean accession RB-2013-007 produced the heaviest 100 seeds. In addition, accession RB-2013-001b applied with Siglat flowered earlier. In terms of ROCE, accession RB-2014-003 applied with Polar Mix resulted in high returns.
