PERTUMBUHAN DAN HASIL KACANG PANJANG (VIGNA SINENSIS L.) AKIBAT PENGGUNAAN DOSIS DAN CARA PEMUPUKAN PHOSFAT DI LAHAN KERING
The experiment was conducted to study the growth and yield of the pea (Vigna sinensis L.) the effect of P fertilizer and application in dryland. The experiment was designed completely randomized block in whkch two factors of treatments were arranged factorially. The first factor was rates of phosfate fertilizers (0, 100, 200 and 300 kg TSP ha -1 ) and the second factor was apllication of fertilizers on three levels (1, 2 and 3 application). Result of this experiment indecated that the effect of interaction betweenrates of phosfate fertilizers and application did not significantly to all of variables. Rates of phosfate fertilizers did not significantly to all of variables. Resulted high seed oven dry weight was found on rates of 100 kg TSP ha -1 was 12,61 g. Which mean increase as high as 145,8 % as comparred to control (0 kg TSP ha -1 ). The application fertilizers was significant on total of pea, dry weight of pea and high significant effect on oven dry weight of pea. High seed oven dry weight was found on fertilizer two application was 14,23 g. Which mean increase as high as 30,50 % as comparred to one application fertilizers.
