THE RESPONSE OF GROWTH AND YIELD VEGETABLE BEAN GENERATION F7 IN SOME LOW LIGHT INTENSITY

Abstract

This study aims to determine the effect of several low light intensities on the growth and yield of F7 generation vegetable beans. This research was conducted in October 2019 to January 2020. The method used was experimental with an experiment in the Agarwood Glasshouse of the Faculty of Agriculture, University of Mataram. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and was repeated 5 times so that 20 experimental units were obtained. Data were analyzed by analysis of diversity at the 5% level. If there is a significantly different treatment (P <0.05) then the follow-up test with the Duncan's Multiple Range Test (DMRT) at 5%. The treatment given is the effect of low light intensity consisting of N0 = 100% light intensity (without shade), N1 = 45% light intensity (55% shade), N2 = 35% light intensity (65% shade), and N3 = intensity light 15% (shade 85%). The results showed that low light intensity had an effect on reducing the weight of seeds per plant, but at low light intensity 35% and 15% were not significantly different, but lower than the low light intensity of 45%. At low light intensity 15% decreases the pod weight per plant, but does not decrease at low light intensity 45% and 15%. In addition, low light intensity results in fewer leaves and branches compared to without shade, but increases leaf area and plant length.
