Efek Mulsa Jerami Padi dan Pupuk Kandang Sapi terhadap Pertumbuhan dan Hasil Bawang Merah di Daerah Pesisir

Abstract

The objective of this experiment was to study the effect of mulching and organic fertilizer on growth and yield
of shallot (Allium ascalonicum L.) in coastal seaboard. The experiment was arranged in Randomized Completely
Block Design (RCBD) with two treatments. First factor are mulching with two levels: without mulch (M0) and with
mulch (M1). Second factor are dosages of organic fertilizer: without fertilizer (P0), 10 T Ha-1 fertilizer (P1), 20 T
Ha-1 fertilizer (P2), 30 T Ha-1 fertilizer (P3), 40 T Ha-1 fertilizer (P4), and 50 T Ha-1 fertilizer (P5). The experiment
treatment was arranged by three replications. The data were analysis by variance and LSD analysis, correlation
analysis, and regression analysis. The results showed that the interaction effects of the mulching and organic fertilizer
on growth and yield of shallot were significantly different , except on the 10 T Ha-1 (P1) to 30 T Ha-1 fertilizer
(P3) the treatment was no effect on total leafs per hill in without mulch (M0). The highest yield of bulb was 7.78
Q Ha-1 without mulch (M0) and 12.27 Q Ha-1 with mulch (M1). The effect of mulching was increase the yield was
35.13 %.
