Comparison of Growth of Azuki, Cowpea and Mungbean with Aeration and Non-aeration under Hydroponic Technique

Abstract

Abstract

The comparison of growth of azuki, cowpea and mungbean on different conditions in the hydroponic technique was investigated. Vigna angularis (azuki), V. unguiculata (cowpea) and V. radiata (mungbean) were cultivated using Kimura A solution at pH 6.5 with aeration and non-aeration. Measurement was determined at 30 days after transplanting. Aeration condition had effect to Vigna species with non-aeration had significantly greater height and leaf area than with aeration while the reverse results were got for the root length and leaf number. However, SPAD of azuki and cowpea in non-aeration were significantly higher than in aeration while mungbean in non-aeration were significantly lower than in aeration. Dry weight of stem, root and whole plant of cowpea and mungbean in non-aeration were significantly higher than with aeration. From these results, azuki, cowpea and mungbean should be cultivated in the non-aeration condition. They would give more growth and yield.
