PENGARUH LEVEL BOKASHI KOTORAN AYAM DAN TINGKAT KEPADATAN POPULASI TANAMAN TERHADAP PERTUMBUHAN VEGETATIF SORGUM BROWN MIDRIB (BMR)

Abstract

EFFECT OF LEVEL BOKASHI CHICKEN MANURE AND PLANT POP­ULATION DENSITY ON VEGETATIVE GROWTH OF BROWN MIDRIB (BMR) SORGUM. The aims of this experiment was to study the interaction of bokashi chicken manure and plant population density on vegetative growth of sorghum Brown Midrib (BMR). Level bokashi were A1 = 0 G; A2 = 200 G; A3 = 400 G and A4 = 800 G/polybag interact with plant population density B1 = 2 plants; B2 = 4 plants and B3 = 6 plants/polybag. Treatments were arranged in a 4 x 3 factorial with 3 replications based on a Completely Randomized Design (CRD). Variable measured were leaf length of leaf, number of leafes and plant height. The results showed that the interaction of treatment had significant effect on leaf length (P<0.05), but did not have significant effect (P>0,05) on number of leafs and plant height. Each treatment gave significant different effect on these both variable (P<0.05). Based on this results can be concluded that to get optimal vegetative growth of sorghum BMR needs bokashi fertilizer by 400 G/polybag at density of 2 plants/polybag.
