Abstract

Most developing areal for peanut crop (Arachis hoypogeae) is upland, that is dominated by parent soil and has acidcharacteristis. Main constraints for this soil are pH and low soil productivity. Dolomite plus is a dolomite ameliorant,with phosphate nutrient. The dolomite plus beside as the ameliorant and a source of magnecium and calciumnutrients, also as a source of phosphate nutrient. The objective of the research was to study effectivity of dolomiteplus on peanut growth in Inceptisols soil. This research was conducted in the greenhouse using a randomizecompletely designed with 8 treatments and 5 replications. The treatments were control, NPK, and combinations ofNPK with six dolomite plus levels. Relative Agronomic Effectiveness (RAE) analyses was used determine to theeffectivity of dolomite plus. The result showed that application of dolomite plus 1,600 kg ha-1 with NPK fertilizerincreased dry weight of grain yield untill 27% (11.53 to 14.65 g plant-1) compared to NPK fertilizer application alone,that was showed by RAE > 100% or among 171-251%. Application of dolomite plus with NPK increased soil pH, soilavailable P (Bray 1), Ca and Mg exchangeable, and CEC as 1.9 unit; 6.2 mg kg-1; 15.87 cmol(+) kg-1; 14.27 cmol(+)kg-1; and 17.29 cmol(+) kg-1 respectively. Maximum rate of dolomite plus was 2,500 kg ha-1 with the yield was 14.2 gplant-1 grain dry weight. The rate of dolomite plus that was higher than 2,500 kg ha-1 could decrease the yield[How to Cite: Sutriadi MT and D Setyorini. 2012. Response of Peanut due to Application of Dolomite Plus.

Abstract

Fertilization of K is very important to increase product agriculture besides fertilization of N and P. In this time usage fertilizer not yet proportional and rational, such as those which happened in usage rice field fertilizer of K for the crop of paddy tend to excessively. The other way in the upland needing more fertlizer but fertilized slimmer or is not fertlized K. Proportional and rational fertilization can reach if pay attention the nutrients dynamics and soil status, and also requirement of nutrient for this crop to reach optimum production. This approach can be executed better and profit if fertilization recommendation based on by result of research soil testing.  Research goal to to determine requirement of K fertilizer  for maize in Typic Kandiudox. The experiments used split-plot design, as main plot are five status nutrients and as sub plot are five treatments of K levels, three replications. The levels of K treatment were 0, 20, 40, 80, and 160 kg K/ha from KCl fertilizer and as indicator crop was maize cultivar P-12.  The result showed that NH4OAc. pH 4,8, NH4OAc. pH 7,0, and HCl 25% were selected extraction methode to estimate K fertilizer requirement  for Maize (Zea mays L.) in Typic Kandiudox and NH4OAc. 1 N pH 4,8 was the best extractan, because get highest coefisien corelation. The K status can be grouped into three classes of availability of K are low, medium, and high with the critical limit for each extractan are 5,0; 10,0; dan 130 mg kg-1 K2O for NH4OAc. 1 N pH 4,8, NH4OAc. 1 N pH 7,0, and HCl 25 % extractants respectively. Optimum dosages of K fertilizer was 150 kg ha-1 and 75 kg ha-1 KCl each for the low and medium status and do not be fertilized for the high status.

Abstract

Calibration of soil P test was conducted for Typic Kandiudox derived from Way Pangubuan, Lampung. A field experiment was carried out in dry and wet seasons. The dry season experiment in 2013 was designed by applying various soil P status: 0 X (very low), ¼ X (low), ½ X (medium), ¾ X (high), dan X (very high), in which X was the amount of P required to obtain P concentration of 0.2 mg P L-1 in soil solution. The wet season experiment was conducted in 2013/2014 with the P treatments of P fertilizer at 0, 8, 16, 33, dan 66 kg P ha-1 in the form of SP-36 with 3 replicates. The results showed that Colwell, Morgan-Wolf, and Olsen extraction methods were not suitable to determine P requirement for upland rice grown on Typic Kandiudox. Extraction methods of Bray-1, Truog, Mehlich, HCl 25%, dan Bray-2 were appropriate to estimate P fertilizer requirement for upland rice. Among all of these extractions, Bray-1 and Truog were the most appropriate. The level of soil P availability extracted using Bray-1 were classified into low (< 12.0 ppm P2O5), medium (12.0-26.0 ppm P2O5), and high status (> 26.0 ppm P2O5), whereas soil P availability status extracted using Truog consisted of low (< 9.0 ppm P2O5), medium (9.0-15.5 ppm P2O5), and high (> 15.5 ppm P2O5).  Phosphorus fertilizer recommendation for upland rice grown on Typic Kandiudox with low, medium, and high soil P availability status were 33, 8, and 0-4 kg P ha-1, respectively, which equal to 200, 50, and 0-25 kg SP-36 ha-1, respectively.
