Abstract

This research was conducted in August - November 2019 in Tungkaran Village (Maju Bersama Farmer Group) Martapura Kab. Banjar, South Kalimantan Province and Laboratory of Agroecotechnology Production, Faculty of Agriculture, ULM Banjarbaru. This experiment used a completely randomized design (CRD) 2 factors which included 5 doses of N fertilizer (first factor) and 4 doses of bokashi fertilizer (second factor) with 2 replications. The results of this research stated that the most significant impact on the interaction of N and bokashi fertilizers were plant height (28 dast and 35 dst), plant wet weight, plant dry weight, number of seeds / rows, many cob weighted and many ears without weight. sweet corn plants, namely the N fertilizer at a dose of 90 kg N/ha to 180 kg N/ha as well as the bokashi fertilizer at a rate of 15 tons/ha.

Abstract

Rubber is one of the mainstay commodity plantations that plays a role in the national economy, including in the economy of South Kalimantan Province. The purpose of this study was to determine the fertility status of Ultisols in rubber plantations in Cempaka District, Banjarbaru City, South Kalimantan Province. Using a survey method, the rubber planting location was determined through purposive sampling. Observation variables include pH H2O 1:5; cation exchange capacity, CEC (me / 100 g) and base saturation, KB (%) 1N NH4OAc extract pH 7.0; P-total (mg / 100g) and K-total (mg / 100g) 25% HCL extract; and the C-organic (%) Walkey and Black method. The soil fertility status was determined according to PPT, 1995. The results showed that Ultisol soil in rubber plantations in Cempaka District, Banjarbaru City, South Kalimantan Province had low fertility status. This low fertility status is due to the nature of the soil which has acid criteria, a pH of 4.90; KTK is classified as medium criteria, amounting to 18.78 me / 100 g; KB is classified as very low, amounting to 9.99%; P-Total classified as low, a number of 4.63 (mg / 100g); K-Total classified as low, worth 16.32 (mg / 100g); and C- Organic which is included in the moderate criteria, amounting to 2.11%. This study revealed that the main inhibiting factors for soil fertility in rubber plantation in Cempaka District were pH, KB, P-total, and K-Total. To improve soil fertility status, calcification, addition of organic matter, and fertilization can be carried out.

Dewi I, Langai FB, Supriyanto UB. 2020. Work capacity and efficiency of hand tractors for soil processing in tidal swamp lands type C and semi-technical irrigation in South Kalimantan. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The working capacity of soil processing machines is very important to test in order to determine the performance of these tools, considering that so far tractor assistance is top down not bottom up, so that tractor assistance designed in Java, which generally has alluvial lands, needs to be tested for its performance in South Kalimantan which generally dominated by swamps. The purpose of this study was to describe the performance of the hand tractor in tidal swamp land type C and semi-technical irrigation. The method used in this research is an experimental method without design and presented descriptively. The parameters tested are actual working capacity, theoretical working capacity, work efficiency, fuel oil consumption. The results showed that the actual working capacity and the theoretical working capacity of the hand tractor in tidal swamp type C and semi-technical irrigated land were 0.159 ha/hour, 0.122 ha/hour, 0.364 ha/hour and 0.371 ha/hour, respectively. Work efficiency is 43.7% and 32.9%. Consumption of fuel oil 0.48 liters and 0.71 liters.

Abstract

The study aimed to determine the response of growth and yield of kailan on the interaction effect of a dolomite lime with bokashi of cow manure and its single factor effect. The experiment was conducted in Completely Randomized Design (CRD) with two factors in three replications. The first factor was dolomite lime which consists of 2 t ha-1 (k1), 5 t ha-1 (k2), 10 t ha-1 (k3) and 15 t ha-1 (k4), while the second factor was bokashi of cow manure consisting of 0 t ha-1 (b0), 10 t ha-1 (b1), 15 t ha-1 (b2), and 20 t ha-1 (b3). By observing growth components consisting of relatif growth rate (RGR), crop growth rate (CGR), net assimilation rate (NAR), shoot/root ratio (S/R), and crop yield. As well as the components of soil nutrient content of N, P, K, C-organic content, pH and cation exchange capacity (CEC). The results showed that the application of dolomite lime at a dose of 15 t ha-1 with bokashi fertilizer at a dose of 20 t ha-1 give the highest value of crop growth rate (CGR), net assimilation rate (NAR), shoot/root ratio (S/R), C-organic content, phosphorus (P), and Potassium in peat soil. The application of bokashi fertilizer at a dose of 15 t ha-1 was not different with 20 t ha-1 in terms of relatif growth rate (RGR), crop yield and cation exchange capacity (CEC), and respectively higher than the dose of 10 t ha-1 and without bokashi fertilizer. The application of dolomite lime at a dose of 10 t ha-1 was not different with 15 t ha-1 on the relative growth rate (RGR), and pH of peat soil, and each dose was higher than the doses of 5 t ha-1 and 2 t ha-1 . In terms of nitrogen (N) content, the application of dolomite lime at a dose of 5 t ha-1 was not different with the dose of 10 t ha-1 , and 15 t ha-1 , the N content was higher than the dose of 2 t ha-1 . The increase in the dose of dolomite lime at 20 t ha-1 of bokashi fertilizer showed a positive linier correlation, except for the Potassium which showed a quadratic correlation. The increase dose of dolomite lime in the bokashi fertilizer, the plant growth rate (PAR), net assimilation rate (NAR), shoot/root ratio (S/R), C-organic content, and phosphorus (P) would increase as well. Each single factor of the dose of dolomite lime and bokashi fertilizer showed a positive linier relationship to the relatif growth rate (RGR), crop yield, N-total, pH, and cation exchange capacity (CEC) of peat soil, except for N-total and pH in bokashi fertilizer.

Abstract

Banjar Regency in South Kalimantan is the center of jasmine production. The productivity level of the province of South Kalimantan cannot make a large contribution to national jasmine production because the harvested area of South Kalimantan is less competitive than Central Java, this is unforgettable because there are differences in agronomic actions and soil chemical properties. This study analyzed the relationship of agronomic actions and soil chemical properties and the dominant traits affecting the productivity of jasmine in the Banjar Regency. This study adopted survey methods and field observations.The survey method included determining the sampling locations and interviews with jasmine farmers. The selected villages were determined by purposive sampling method by deliberately choosing villages that were dominant in cultivating jasmine plants, namely Labuan Tabu village, Jingah Habang Ilir village, and Pandak Daun village. The results revealed that the agronomy action and soil chemical properties simultaneously had A significant effect on the yield of jasmine. Each of the treatments of nitrogen application, potassium application, and pruning frequency significantly affected the yield of jasmine. The dominant agronomic actions on the yield of jasmine were nitrogen application, pruning frequency, and potassium application, with the contribution of 46.51%, 17.72%, and 17.14%, respectively. The indirect effect of nitrogen fertilizer application channeled through the pruning frequency contributed 18.19% higher than the direct effect of the pruning frequency alone. The indirect effect of potassium fertilizer application through the pruning frequency contributed 16.33% to the jasmine productivity. The application of N fertilizer and the pruning frequency showed a very significant and positive linear relationship to productivity with regression equations of 5.173+0.01526 N and –0.194+3.587 Fpks, respectively.
