Abstract

Management of peat soil for pineapple cultivation in Kualu Pineapple Village is still very traditional. In planting not using spacing, fertilization only uses fertilizers containing N, namely urea. In addition, there are differences in principles in managing peat, namely that there are farmers who add ameliorant ingredients and some do not. The purpose of this study was to determine the chemical properties of the soil, and nutrient uptake of pineapple plants in Kualu Nenas Village where the soil was given dolomite lime ameliorant and without ameliorant. This research method uses qualitative (survey) and quantitative (laboratory analysis) methods. A sampling of plants whose soil was given dolomite lime ameliorant and soil without ameliorant was carried out by purposive sampling technique. The research data were analyzed by a T-test to determine the difference between the chemical properties and nutrient uptake of pineapple plants. The T-test was analyzed using the SAS program (SAS User Manual Version 9, 2004). The results of this study were that the soil PH, P-available, K-dd, Ca-dd, Mg-dd, CEC, and base saturation content in pineapple plantations where the soil was treated with dolomite lime ameliorant had a significantly higher value based on the T-test compared to pineapple plantations with no ameliorant. Nutrient uptake of N, P, K, Ca, and Mg in pineapple leaves was not significantly different between plants whose soil was treated with dolomite lime ameliorant and those without ameliorant.

Abstract

The purpose of this study was to determine the interaction and main effects of biochar residue and POC NASA applications to increase growth and production and nutrient uptake of peanut plants. This research has been carried out at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City. The research was carried out for 4 months from January to April 2021. The design used in this study was a factorial completely randomized design (CRD) consisting of 2 factors, the first factor was biochar residue (B) which consisted of 4 treatment levels, namely biochar dose 0; 0,7; 1.4; 2,1 kg per plot. The second factor is POC NASA which consists of 4 treatment levels, namely POC NASA concentration 0; 3; 6; 9 ml/L of water. Parameters observed were relative growth rate, number of pods, the weight of wet pods per plant, the weight of dry pods per plant, and nutrient uptake of N, P, K in plants. Observational data from each treatment were statistically analyzed and continued with the further test of Honest Significant Difference (BNJ) at the 5% level. The results showed that the residue biochar and POC NASA had a significant effect on all observed parameters except for plant nutrient uptake parameters of N, P, and K. In terms of interaction and main, the best treatment was biochar residue, the dose of 2,1 kg/plot and POC NASA with a concentration of 9 ml/liter of water (B3P3).
