Respon Tanaman Jagung Manis (Zea Mays Saccharata Sturt.) Terhadap Pemberian Biochar Pelepah Kelapa Sawit Dan Pupuk Npk Pada Tanah Ultisol
Increasing sweet corn production can be achieved by intensifying the use of marginal land such as Ultisol soil which has low fertility. Efforts that can be made are by providing biochar and fertilizing. The research aims to study the effect of applying palm frond biochar and NPK fertilizer, and their interaction on the growth and yield of sweet corn plants. This research was carried out in Mandiangin village, Minas, Siak and Soil Science Laboratory, Faculty of Agriculture, University of Riau from June to September 2022. This research was carried out experimentally in 3x3 factorial form using a completely randomized design. The first factor, namely the palm frond biochar dosage, consists of 3 levels (0, 2,5 and 3,5 ton.ha⁻¹). The second factor, namely NPK fertilizer, consists of 3 levels (0, 300 and 400 kg.ha⁻¹). Observation parameters consisted of pH, N-total, P-available, CEC, plant height, leaf area, age at which male flowers appeared, age at which female flowers appeared, age at harvest, weight of cobs with husks, and weight of cobs without husks. Palm frond biochar 12,5 g per polybag increases soil pH, available P, total N, and CEC, plant height, leaf area, accelerates the appearance of male and female flowers, ear weight without husk, and harvest time. NPK fertilizer 1,5 g per polybag increases leaf area, husked cob weight and speeds up harvest maturity. The combination of palm frond biochar 12,5 g per polybag with NPK 1,5 g per polybag showed that the growth and yield of sweet corn plants tended to be better compared to other treatments in all parameters, except the weight of sweet corn husk cobs.
