PERUBAHAN SERAPAN NITROGEN TANAMAN JAGUNG DAN KADAR Al-dd AKIBAT PEMBERIAN KOMPOS TANAMAN LEGUM DAN NONLEGUM PADA INSEPTISOLS NAPU
Abstract
The glass house experiment conducted was aimed at identifying changes in N uptake by maize plant and soil exchangeable aluminum at Inceptisol Napu. The experiment used a Randomized Block Design with treatments consisting of 10 t ha-1 compost of various types: n 0= with no compost (control), n a= cacao compost, nb= maize residue compost, n c= paddy straw compost, n d= johar compost, ne= gamal compost, and nf= ground nut residue compost. Each treatment was replicated three times. Sweet maize was used as a tested plant with parameters observed were: (1) soil pH, (2) soil Ntot, (3) Alexch, and (4) N uptake. Data were analysed using ANOVA in conjunction with Tukey’s honestly significant different test at 5% level. The experimental results showed that the compost significantly improved the soil chemical characteristics such as increasing soil pH and soil Ntot and N uptake, and decreasing Alexch. The N upatake by maize was also increased with the highest uptake found in the johar compost treatment.
