Abstract :
ABSTRACT AFFANDY SAHALA TUA MARPAUNG. A. 1710957. Effects of Nitrogen Source Organic Fertilizer Application on the Growth and Production of Green Bean (Phaseolus vulgaris L.). Under immediate Supervision of Arifah Rahayu and Nur Rochman. This study was aimed at assessing the effects of the application of different types of N source liquid organic fertilizers (LOF) on the growth and production of green beans (Phaseolus vulgaris L.). The study was conducted at the Trial Farm of Djuanda University, Bogor, West Java. A completely randomized design was used. Treatments consisted of 11 levels of fertilizer applications, namely no fertilizer, 100% R mexican sunflower, 100% R kirinyuh (Chromolaena odorata), 100% R cattle urine, 100% R urea, 75% R mexican sunflower + 25% R urea, 75% R kirinyuh+ 25% R urea, 75% R cattle urine + 25% R urea, 50% R mexican sunflower + 50% R urea, 50% R kirinyuh + 50% R urea, and 50% R cattle urine + 50% R urea. Results showed that compared to the use of 100% R urea, the application of N source LOF did not give any significant effects on all parameters measured. This indicated that N source LOF could be used as urea alternative in natural farming systems. Key words : green bean, mexican sunflower, kirinyuh, cattle urine
