Yield and Yield Components of Several Mungbean Varieties (Vigna radiata L. wiczek) as A Result of Kieserite Fertilization

Hasil dan Komponen Hasil Beberapa Varietas Kacang Hijau (Vigna radiata L. Wilczek) yang Diberi Pemupukan Kieserit

Abstract

Mungbean is  one of  food plants that has important role as a source of nutrition.  One of the important macronutrient elements which its deficiency can disrupt the photosynthesis process resulting in reduced mungbean growth and yield  is Mg (magnesium).  Research aimed to determine responses of several varieties to  application of different doses of kieserite fertilizer and to obtain the best dose for each varieties. Experiment was arranged in a randomized block design (RBD) with a two-factor factorial pattern. The first factor was four varieties i.e. ‘Vima 1’, ‘Vima 3’, ‘Vima 5’, and ‘Vimil 1’.  Second factor was four levels of kieserit  fertilizer dosage (0, 50, 100, and 150 kg ha^-1). Observed variables were yield and yield components. Data were analyzed using analysis of variance  and Duncan's test at 5%  α level. Results showed that the responses of four varieties used were relatively the same to the dose of kieserit, and dose aplication of  kieserit  50 kg.ha^-1 could increase yield. Highest yielding variety was Vima-5 variety with  highest number of pods and yield per plant. While the lowest yielding variety was Vimil-1 variety  which had lower seed size (weight 100 seeds)  than of other varieties.
