Abstract

A number of crop growth simulation models have been developed using the radiation use efficiency (RUE) concept to predict crop growth and yield in various environments. These models generally calculate daily biomass production as the product of the quantity of radiation intercepted and RUE. Besides that biomass production was deterimined by water and nitrogen available factor. So, this research was carried out to quantify the RUE, biomass and leaf area index on Jatropha under rainfall condition, four levels of nitrogen fertilizer (N) and two and three population densities (P) planted twice. The experiments used a systematic Nelder fan design with 9 spokes and 4 – 5 rings were conducted at SEAMEO-BIOTROP field experiment in 2007. Data from the first experiment were used for parameterization and calibration and the second experiment data for model validation. Based on parameterization, we found that RUE can prediction above ground biomass accumulation of Jatropha were 0.94 (r=0.83) g MJ-1 to 1.3 (r=0.75) g MJ-1. Water availability was between ψ=-30 kpa and ψ=-1.5 MPa for field capacity and wilting point, respectively. Nitrogen demand of root, stem, leaf and grain N were (Ndemr=0.75), (Ndems=0.60), (Ndeml=2.53), and (Ndemg=2.41), respectively. Validation showed that model can simulate crop growth and development of Jatropha.

Abstract

Plant growth interpretation in term of accumulated intercepted solar radiation and the radiation use efficiency (RUE) was used to study the growth and analysis of Jatropha (Jatropha curcas L.). A number of crop growth simulation models have been developed using the RUE concept to predict crop growth and yield in various environments. These models generally calculate daily biomass production as the product of the quantity of radiation intercepted and RUE. This research was carried out to quantify the RUE, biomass and leaf area index on Jatropha under rainfall condition, four levels of nitrogen fertilizer (N) and three population densities (P) planted twice. The experiments used a systematic Nelder fan design with 9 spokes and 4 – 5 rings were conducted at SEAMEO-BIOTROP field experiment in 2007. Data from the first experiment were used for parameterization and calibration and the second experiment data for model validation. Values of RUE were determined by nitrogen fertilizer and plant density. Based on parameterization, we found that RUE for prediction above ground biomass accumulation of Jatropha were 0.94 (r=0.83) g MJ-1 to 1.3 (r=0.75) g MJ-1.

Abstract

Management strategies development for efficient water utilization of crop production requires sensitive measurements of changes in soil water content on a dynamic basis. Many of the methods currently used for measuring these changes are destructive, slow, or relatively expensive for large-scale investigations. A sensor that low-cost, nondestructive soil moisture sensor for measuring changes in soil volumetric water content on the basis of changes in the dielectric constant of the soil water were available. So, this research was carried out to quantify soil water content on Jatropha under rainfall condition, four levels of nitrogen fertilizer (N) and two population densities (P). The experiments used a systematic Nelder fan design with 9 spokes and 4 rings were conducted at SEAMEO-BIOTROP field experiment in 2007. Based on evaluation this instrument can use to measurement soil water content in various environment.

Abstract

This study aims to obtain the right composition in the use of water hyacinth bokashi that can substitute inorganic fertilizer in pepper plants. This research was carried out using polybag at plantation CV location. Gunung Putri Martapura for 4 months from January to May 2018 with experimental design of Randomized Non-Factorial Complete (RAL) with 5 treatment of plant media composition, namely: p0 = soil + 100% NPK “Mutiara” (without water hyacinth bokashi); p1 = soil: water hyacinth bokashi (3: 1 / v: v) + 75% NPK “Mutiara”; p2 = soil: water hyacinth bokashi (2: 2 / v: v) + 50% NPK “Mutiara”; p3 = soil: water hyacinth bokashi (1: 3 / v: v) + 25% NPK “Mutiara”; p4 = soil: water hyacinth bokashi (1: 3 / v: v) (without NPK “Mutiara”). Each treatment was repeated 4 times so that the entire plot of the experiment was 20 plots. Each plot consists of 5 plants so that there are 100 plants in total. Observations were made on plant height, stem diameter, the number of leaves, length of the segment, sprout age, and dry weight of the plant. Based on the result of the research, the treatment of various plant media composition has no significant effect on plant height, stem base diameter, leaf number, and dry weight of plant, but significantly affect the age of sprout and length of pepper plant so it can be concluded that water hyacinth bokashi in early the growth of pepper plants cannot substitute inorganic fertilizers but can be complimentary of inorganic fertilizers. The best cultivation plant composition treatment on pepper seedling in this study was on soil composition: water hyacinth  bokashi  (3: 1, v: v) + 75% NPK “Mutiara” and on soil composition: water hyacinth bokashi (2:2; v: v) + 50% NPK “Mutiara”.

Abstract

The tendentious issue of deforestation, biodiversity, "water greedy" attack ganoderma and carbon emissions continue to heat up in this decade has cornered palm plantations in Indonesia for allegedly either from outside or from inside the country becomes the base of why. To clarify these issues then this article aims to analyze the impact of oil palm plantations in terms of the water balance of plant oil palm. Water use in the oil palm plantations on average 92.05 mm/month or equivalent to 1104.5 mm/year over lamtoro stands is 3,000 mm/year, acacia 2,400 mm/year, sengon of 2,300 mm/year, amounting tea 900 mm/year, rubber amounted to 1,300 mm/year, bamboo amounted to 3,000 mm/year and teak amounted to 1,300 mm/year. The coefficient of oil palm crop of 0.93. The percentage amount of rainfall used palm oil amounted to only 39.60% of the annual rainfall. Percentage of evapotranspiration value is smaller than the value of evapotranspiration pine percentage of 64.5%, A. mangium 68.8%, amounting to 55.1% of ferns and eucalyptus (E.alba) amounted to 52.4%. Meanwhile, rubber plant has a value of 1 kc, other crops such as rice, during the period of growth has kc values between 1.05 to 1.2. Soil water content (KAT) which indicates the storage capacity of the root zone of oil lower than the root zone rubber (Rusmayadi, 2011). This is due to the oil more roots growing in the topsoil to a depth of ± 1 meter and as you go down the less. Rooting most densely contained at a depth of 25 cm. Therefore the ability of smaller savings in oil palm plantations compared to rubber, then the excess water will be removed or overflowed (Ro) is not taken ("greedy water") by palm trees. Palm oil as a commodity to be seen objectively with regard to the nature of biological (plant roots), physiological (crop coefficient), and environmental (water storage capacity). This is to straighten out the problems that it is not water but greedy oil plantation management who do not pay attention to aspects of water conservation.

Abstract

The irregularity of observation sites distribution and network density, lack data availability and discontinuity are the obstacles to analyzing and producing the information of agroclimate zone in South Kalimantan. TRMM satellite needs to be researched to overcome the limitations of surface observation data. This study intended to validate TRMM 3B43 satellite data with surface rainfall, to produce Oldeman agroclimate zone based on TRMM satellite data and to analyze the agroclimate zone for agricultural resources management. Data validation is done using the statistical method by analyzing the correlation value (r) and RMSE (Root Mean Square Error). The agroclimate zone is classified based on Oldeman climate classification type. The calculation results are mapped spatially using Arc GIS 10.2 software. The validation result of the TRMM satellite and surface rainfall data shows a high correlation value for the monthly average. The value of correlation coefficient is 0,97 and 25 mm for RMSE value. Oldeman agroclimate zone based on TRMM satellite data in south Kalimantan is divided into five climate zones, such as B1, B2, C1, C2, and D1.
