Kajian Irigasi Defisit Pada Tanah Ultisol terhadap Pertumbuhan Tanaman Buncis (Phaseolus vulgaris L.)

Abstract

The level of water application in bean plants can affect the growth and production of bean plants (Phaseolus vulgaris L.). This study aims to determine the effect of deficit irrigation on the growth of bean plants (Phaseolus vulgaris L.). The study was conducted on a greenhouse scale using a non-factorial completely randomized design with 4 treatments and 5 replications. The results showed that the ultisol soil had a loamy sand texture and an organic matter content of 1.75%. The wet weight of bean plants in the treatment of 40% KL and 60% KL was significantly different from the treatment of 80% KL and 100% KL, and the best wet weight of the bean plant in the 80% treatment. Field Capacity was 49.60 grams. The water treatment did not give a significant effect on the dry weight of the bean plant, the number of bean pods, and the weight per bean pod. The weight of bean pods per plant in the 40% KL treatment was significantly different from the 60% KL, 80% KL, and 100% KL treatments. The best weight of chickpeas per plant was in the treatment of 60% KL of 15.04 grams. The optimal water productivity was obtained at the 60% KL treatment of 1,15 Kg/m3.
