Abstract

Climate change and the erratic and uneven rainfall distribution are the causes of reduced water available in the soil for plant needs to the transpiration process. This study aimed to determine coffee transpiration rate on dry land with rain harvesting techniques during the dry season, transition season, and rainy season and the factors that influence it. This study used field observation and laboratory analysis with two treatments, i.e. a bench terrace as a control (P1) and an L-shaped silt pit (P2). The variables observed were soil moisture content, transpiration rate, soil water potential, leaf water potential, and microclimate, especially temperature and sunlight intensity. The results showed that the transpiration rate of coffee plants was significantly different in the two treatments. The highest transpiration rate was found in P2 as much as 13.17 mm week-1 or equivalent to 1.88 mm day-1 during the dry season. Application of the L-shaped silt pit (P2) increased soil moisture content compared to the control (P1). This increase was followed by an increase in soil water potential and leaf water potential, which could reach the highest values of 0.18 bar and 0.49 bar, respectively. The transpiration decreases with the change of seasons from the dry season to the transitional season and the rainy season. This decrease is caused by changes in the microclimate, especially the temperature and sunlight intensity. Both are the most variables that affect the rate of transpiration.

Abstract

The success of sugar cane production is affected by the condition of the plant in the early phase (germination). The improvement of sugarcane growth can be done by improving soil physical properties using organic matter such as mature compost, blotong, and biourine of rabbit. The objective of this study was to explore the effects mature, blotong, and biourine of rabbit on soil aggregate stability and the early growth of the sugar cane (germination phase). The experiment was held in P3GI (Pusat Penelitian Perkebunan Gula Indonesia) in Pasuruan, Jawa Timur. The experiment used randomized block design with 8 treatments and 5 replications. The treatments were P0 control (without organic matter), P1 (blotong t ha-1), P2 (mature compost 20 t ha-1), P3 (biourine of rabbit 10 L ha-1), P4 (mature compost 20 t ha-1 + blotong t ha-1), P5 (biourine of rabbit 10 L ha-1 +blotong t ha-1), P6 (biourine of rabbit 10 L ha-1 +  mature compost 20 t ha-1), P7 (biourine of rabbit 10 L ha-1 +  mature compost 20 t ha-1 +blotong t ha-1). The results showed that the application of combination of mature compost, blotong, and biourine of rabbit affected soil aggregate stability. The highest value in 12 MST was in biourine 10 L ha-1 + mature compost 20 t ha-1 (P6) was 3.41 mm. Application of mature compost 20 t ha-1 + blotong t ha-1 (P4) gave highest plant height of  84.62 cm

Abstract

Typic Kanhapludult is a soil of Ultisol order that has water availability constraints due to the low available soil water pore and soil water holding capacity so that less support the plant growth. Application of soil amendments such as oil palm shell biochar can help increasing soil water retention and available nutrients to improve plant growth. The objectives of this study that was conducted in the glasshouse of Balai Penelitian Tanah, were to quantify the effect of biochar high doses to soil water retention, to improve some of soil physics and soil chemistry, and to analyze the potential utilization of palm oil shell biochar on vegetative growth of maize in a Typic Kanhapludult. The results of this study showed that application of high doses of oil palm shell biochar increased the soil water retention. Application of high dose of oil palm shell biochar significantly decreased bulk density and particle density, decreased rapid drainage pore, and increased porosity and available water pore. However, it did not significantly affect the saturated hydraulic conductivity and slow drainage pore. Soil organic carbon increased significantly while the soil acidity at the end of experiment increased from very acid to acid. Application of oil palm shell biochar increased maize height, fresh and dry weight of maize. While the stem girth and the number of leaves per plant were not significantly affected.

Abstract

Entisols are soils with low organic matter and sandy texture. Soil with this characteristics generally have problems in the provision of nutrients for plants, especially of N due to the high nutrient leaching process. One effort that can be done in addressing the issue is with the addition of inorganic fertilizer and organic fertilizer. Inorganic fertilizers which contain N and frequently encountered is urea. Cow urine and waste compost tea are liquid organic fertilizers which have the potential to be developed as rich elements of N, P, K that are needed by plants. The purposes of this study were to determine the influence of urea and liquid organic fertilizer for crop N uptake and production of mustard (Brassica juncea L), and to determine the optimum dose of urea and liquid organic fertilizer for the production of mustard on Entisols. The results showed that the application of urea and liquid organic fertilizers significantly affected N uptake in mustard. Dose combination of 50% Urea (0.22 g polybag-1) and 50% liquid organic fertilizier (110.91 mL polybag-1) resulted in the highest N uptake value 15.81 g plant-1 compared to the control treatment of 3.11 g plant-1 and resulted in an increase in the height, number of leaves leaf area, fresh weight as well as the mustard dry weight, respectively for 74.88%; 80.00%; 353.95%; 177.40%; 104.73%. Dose combination of 50% Urea (0.22 g polybag-1) and 50% organic liquid fertilizier (110.91 mL polybag-1) was the most effective dose of fertilizier to meet the needs of N in mustard

Abstract

Ultisols are characterized by less aggregate stability, high clay, solid, organic material, and low pH. These can be managed by using calcification, augmentation of organic material and fertilization. One of soil amendments than can be used to improve properties of Ultisol is biochar.  The objective of this study was to elucidate the effects of cocoa's shell biochar application on soil aggregate stability and growth and yield of maize at an Ultisol. Treatments tested in this study were D0 (no biochar application), D5 (application of 5 t biochar ha-1), D10 (application of 10 t biochar ha-1), D15 (application of 15 t biochar ha-1), D25 (application of 25 t t biochar ha-1), dan D40 (application of 40 t biochar ha-1). The results showed that in one growing season giving some doses cocoa's shell biochar had not been able to affect soil aggregate stability. The highest aggregate stability was found at treatment of 15 t ha-1 of cocoa’s shell biochar with an index of 130.12. The increased levels of soil organic C was followed by the increase in aggregate stability index. The highest organic C was found at D40 treatment with 4,09%. While the highest retention of water was found at the D10 with 32,96%. The increased aggregate stability index was not followed by the ability of soil to retain water. The addition of cocoa's shell biochar could increase soil organic C but not in line with the ability to retain water. If cocoa's shell biochar was given at the hig dose then it can give high maize yield.

Abstract

This study was held based on climate change impact as a present and future environmental issues on sustainable agriculture especially it’s impact on crop water availability. This study aimed to determine the impact of climate change on the water availability of sugarcane that was simulated using climate change scenarios based on global climatic analysis. Climate change was simulated for future scenarios using combination of temperature increase (2o, 4o, and 6o C) and rainfall change (∆CH -10, ∆CH -5, ∆CH +5, ∆CH +10%) from actual condition. This study took place at Wajak, Sumbermanjing, and Gedangan sub-districts, choosen by sugarcane plantation area with different soil conditions, especially soil texture. The result showed water demand increased 5-15% with the increasing of temperature, thus could impacting crop water availability especially during dry months period which could not fulfill crop water needs. The highest potential reduction was in Gedangan site which reached 5,1% in the C9 scenario (temperature + 6o C and rainfall -10%). The high quality in holding water could not assure the low potential reduction because it also depends on climatic conditions.

Abstract

The condition of increasing the demand for sugar is not balanced with the production of sugarcane because the production from year to year fluctuates. Continuous inorganic fertilization in sugar cane causes a decrease in soil productivity. This study that was aimed to determine the potential of biological fertilizer as a provider of soil nutrients to reduce the use of inorganic fertilizers for sugarcane was conducted at Sugar Research Center PT. Perkebunan Nusantara X Kediri. This study consisted of planting stage of sugarcane plant, application of liquid combined biofertilizer and observation of vegetative growth of sugar cane plant, and soil nutrient analysis. This study used a randomized block design using seven treatments with four replications. The treatments tested were P0 (without biofertilizer + without NPK fertilizer), P1 (100% NPK fertilizer), P2 (biological fertilizer + 100% NPK fertilizer), P3 (biological fertilizer + 75% NPK fertilizer), P4 (biological fertilizer + 50 % NPK fertilizer), P5 (biological fertilizer + 25% NPK fertilizer), P6 (biological fertilizer). The results indicated that the presence of bacteria could increase the growth of sugarcane and soil nutrients content. The best growth of sugarcane plantation occurred at the treatment of P2 (biological fertilizer + 100% NPK fertilizer).This was suspected to occur because the nutrient needs of the plant could be met quickly by the presence of inorganic fertilizers as well as the help of nitrogen fixing bacteria and phosphate solubilizing bacteria in the biological fertilizer.
