The average productivity of upland rice in Riau Province is still relatively low but it has the potential to be cultivate on marginal dry land like Ultisol by applying rice husk zeolite, Mucuna bracteata liquid organic fertilizer (LOF) and N, P fertilizer. This research aim to study the effect of each composition and obtaining the best composition on the growth and yield of upland rice on podzo…
Maize (Zea mays L.) is a carbohydrate producer that is used as an industrial raw material and animal feed. Maize production in Riau decreased by 15% - 75% due to Spodoptera frugiperda J.E. Smith larvae attack. S. frugiperda must be controlled, but still uses synthetic pesticides that cause resistance, recurgence, and secondary pests. An alternative is to use botanical pesticides from bidara lea…
This study uses a complete random design factorial consisting of two factors. The first factor is TKKS compost with three levels, namely T0 = without empty fruit bunches compost, T1 = 15 t.ha-1 empty fruit bunches compost , T2 = 20 t.ha-1 empty fruit bunches compost . The second factor is the provision of fertilizer P with three levels, namely, P0 = without fertilizer P (SP-36), P1 = 150 kg.ha-…
