Abstract

One of the obstacles in providing irrigation water is the difficulty in determining the right parameters to be used in the controlling of timing and amount of irrigation water according to crop needs. One of the alternative parameters that could be considered in order to meet the water needs of plants is the irrigation control based on evaporation. This study aims to produce an evaporative irrigation system design and determine the crop coefficients of pepper. The drip irrigation network consists of a supply tank and distribution pipes that provide water to the plant pots. The network valve opening and closing arrangements are made based on the evaporation in the supply tank. This research was conducted in a plant house for 5 months by observing the observations made on the water balance components, including the rate of evaporation which is measured based on changes in the water level in the water supply tank. The results showed that the evapotranspiration outside the houseplant was greater than that in the plant house. At the beginning of planting pepper, the evapotranspiration was 5.2 mm/day in the plant house and 4.9 mm/day outside. The average evapotranspiration during observation inside the plant house was 4.1 mm/day and 3.8 mm/day outside. Meanwhile, evaporation outside the plant house is smaller than that inside the plant house which ranges from 2-5 mm/day. Provision of water with this evaporative irrigation system of 5.2 mm/day has been able to meet the needs of 4.1 mm/day of evapotranspiration water for pepper plants. The provision of water has been able to encourage the growth of primary branches and flowering. Normal pepper plant growth during this study with calculated crop coefficients ranging from 0.1–0.7.

Abstract

Problem faced by star fruit farmers in Depok, West Java, is water availability relying only on rainfed. Therefore, research related to water conservation technique for optimum utilization of rain water and runoff at the starfruit orchard was conducted. The objectives of the research were: 1) The relationship between rainfall, evapotranspiration with starfruit productivity, 2) To find out the effects of soil water absoption on starfruit productivity , and 3) To develope water balance analytical model without runoff for sweet starfruit orchard. In this experiment the water table was approximately 16 m from soil surface, no irrigation was used and water storage canals equipped with silt pits were constructed so that runoff component and contribution of water capillarity movement were zero. The research results showed that: 1) The rainfall and evapotranspiration had influence on the starfruit productivity; 2) The relatively high rainfall followed by high soil water content at the rooting zone, ranging from 0,429 to 0,458 m3/m3, enabled the star fruit to have year-round production with four times harvesting; 3) The water balance analytical model without runoff could nicely simulate the soil water content at the rooting zone with R2 of 0,83.

Abstract

This research aims to design a control system to keep the water level and soil moisture at a level that is suitable to the plant requirment and determines the optimum water level and soil moisture in each growth phase of paddy field cultivation. The water level control system was formed based on on-off controls system using Arduino Uno ATMega328P microcontroller. When the sensor gives input that the water level is below the set points, then microcontroller will command the irrigation valve to open and the drainage valve to close. The volume and time of irrigation and drainage control are dependent to set point. Set point was controlled based on water regime treatment. Water regime consisted of three treatments, which are wet regime (RB), slightly wet regime (RAB), and dry regime (RK). The research result showed that control system was very effective and efficient in controlling the water regime according to the control algorithms. Besides, the research result showed that the water regimes affected the plant growth, land productivity, and water productivity. Treatment of wet regime (RAB) gave the highest number of tiller (138 tillers), yield 194.7 g/hill (equal to 21 ton/ha with assumption of 30 cm x 30 cm spacing) and water productivity 3.16 kg/m3.

Abstract

On the determination of crop water requirements, climate data are essential but are often limited due to the farm field's lack of weather station. For this reason, it is necessary to consider plant water requirements with various potential evapotranspiration (ETp) models with various weather input parameters, including Artificial Neural Network (ANN) models. The objectives of this paper were 1) to develop ANN models to estimate ETp, 2) to compare various ETp models (empirical models) including ANN models with the FAO standard models, 3) to analyze crop water requirements by the models, and 4) to determine the recommended input parameters for estimating ETp. The analysis was performed based on the measurement of weather parameters data in the two rice planting seasons, i.e., April - August 2017 and January - May 2018. There are 8 ETp models (empirical models) and 3 ANN models with a combination of input parameters. The results of this study indicated that the ANN-2 model with solar radiation input parameters was the best ANN model with R2 values 0.91-0.92 and RMSE 0.284 mm and 0.287 mm for the 2017 and 2018 planting seasons. ETp Turc model, one of the empirical ETp models with parameters input of air temperature and solar radiation, was the best model with the highest R2 and the lowest RMSE. Therefore, these two models were the best models with total ETp values closed to the ETp FAO standard. In addition, the parameters of air temperature and solar radiation are recommended parameters to be measured in the determination of crop water requirements using the ETp Turc model. But if there is only one parameter that can be measured, it is recommended to measure solar radiation with ANN-2 models to determine potential evapotranspiration.

Abstract

Managing water in the paddy fields, water balance analysis is usually performed to determine the effectiveness of water used. However, with limited advanced instrumentation, time and cost, some water balance components are not measured. This study proposed a novel method, Linear Programming (LP) model, to estimate non-measurable water balance components. The aims of this study were to develop LP model in estimating non-measurable water balance components such as irrigation, runoff and percolation with measured soil moisture data in non-flooded irrigation, and then to evaluate performance of the model by comparing measured and estimated soil moisture. This study was carried out based on two season field experiments of non-flooded irrigation with System of Rice Intensification (SRI) in NOSC, Sukabumi West Java during 20 August to 15 December 2011 (first season) and 22 March to 5 July 2012 (second season). The developed LP model has the objective function by minimizing the differences between total measured and estimated soil moisture. In addition, the LP model has also constraint function and initial condition that were formulated based on actual field conditions. The results showed the LP model estimated non-measurable water balance accurately with the indicators of R2 > 0.85 (p value < 0.01) and percentage error less than 8%. Based on the estimation model results, irrigation only contributed 34-38% of inflow, while crop evapotranspiration and percolation contributed of 40-44% and 11-15%, respectively. Precipitation and runoff were the most contributors of inflow and outflow from the fields. By the current model, water use efficiency and water productivity can be determined with estimated irrigation.

Abstract

In this study, an optimal soil moisture level that maximizes both yield and water productivity of system of rice intensification (SRI) paddy field was simulated by genetic algorithms (GA) model. The GA model was performed to find an optimal combination of soil moisture levels according to the empirical data during three cropping seasons at Nusantara Organic SRI Center (NOSC), Nagrak Sukabumi, West Java. Here, we classified soil moisture level into three levels i.e. wet (W), medium (M) or dry (D) based on the soil water retention curve. As the results, the optimal soil moisture was a combination of wet, wet, medium, and dry levels of soil moisture for initial, crop development, mid-season and late season growth stages, respectively. The wet level in the initial and crop development growth stages should be achieved providing enough water for the plant to develop root, stem and tiller, and then the field can be drained into the medium level with the irrigation threshold of field capacity to avoid spikelet sterility in the mid-season stage, and finally, let the field in the dry level to save more water in the late season stage when plant water requirement is minimum. By this scenario, it was simulated that the yield can be increased up to 4.40% and water productivity up to 8.40% with saving water up to 12.28% compared to the empirical data.

Abstract

Crop coefficient was calculated based on the observation of water consumption of various treated paddy fields on the objective to find its changes with time as the plant grew. Three principal techniques of paddy fields known as System of Rice Intensification, Integrated Crop Management and commonly practiced were investigated. Each of them has major different in irrigating and planting patterns, which lead to different performance on plant growth, productivity and water consumption. In this study, the combinations of irrigating and planting patterns across these 3 systems investigated. Measurements were conducted in daily basis on water level, perched water table, irrigation water, drainage water and weather parameters. Water balance analysis was carried out to calculate equivalent depth of soil water storage, which was then compared with measured soil water storage based on water level data and soil water retention curve. The results showed that each treatment produced similar crop coefficients. Average crop coefficient in 15 days periods are 0,87, 1,03, 1,13, 1,24, 1,28 and 1,25. These values are important to understand more about water saving mechanism as an input to develop irrigation discharge planning standard.

Abstract

Determination of watering interval and moisture conditioning in sprinkle irrigation requires a supporting technology to optimize the irrigation. Arduino UNO microcontroller was used as an automatic controller that determine in watering based on soil moisture conditions determined by soil moisture sensor. The automatic sprinkle irrigation uses pF parameters to conditioning the soil moisture. Soil potential pF value between 4.2 ≤ pF <2, and are equivalent to the percentage of soil moisture 38.5%≤ soil moisture < 28.7%, were used aslower and upper set point in the automatic irrigation that operates solenoid valve for regulating irrigation water flow from water tank. The result shows that the automatic sprinkle irrigation system could keep the soil moisture between the desired setpoint range and thus can be applied for wider use.

Abstract

The System of Rice Intensification (SRI) has been known in Indonesia since 1999. However, there are some difficulties in utilizing SRI water management recommendations in the field, particularly in combination with organic nutrient management. While many demonstrations have given impressive gains in productivity, many farmers remain skeptical about applying this system. The current study was carried out to analyze water balance components in SRI paddy fields when applying intermittent irrigation. The experiment was conducted in Gabus Wetan village, Indramayu District, West Java, Indonesia from 17 Nov 2016 to 1 March 2017. We involved a local farmer who had been trained in SRI methods at an Organic SRI Center on how to conduct organic SRI management in his fields. Weather and soil sensors were set up in the fields to acquire data on daily field conditions as well as on plant growth. Data on weathers such as precipitation, air temperature, relative humidity, and wind speed were collected automatically during the season every 60 min, as well as the soil water depth. Analyzing the data collected, water balance analysis was well performed with low error (1.00%) in which the water inflows through precipitation and irrigation were 560 mm and 865 mm, respectively, while the outflows by crop evapotranspiration, percolation, and runoff were 430, 306 and 675 mm, respectively. Compared to conventional rice farming as commonly practices by applying continous flooding irrigation, water productivities of organic SRI were 30% and 27% higher with respect to total water input (WPIR) and with respect to the amount of evapotranspiration (WPET, respectively. Organic SRI produced 33% higher yield than that the average of conventional methods in the same subdistrict. The key was intermittent irrigation by maintaining shallow water depth (nearly soil surface) in the vegetative and generative stages. Therefore, it is an attractive option to farmers in irrigated areas where water resources is limited due to regional climate change effects. Keywords:

Abstract

Paddy is the main agricultural commodity in Indonesia that needs a large amount of water. Accurate prediction of crop water use is essential to have an efficient irrigation system. The actual evapotranspiration (ETc) is an important factor for estimating water use. Moreover, crop coefficient (Kc) is one of the important parameters in ETc calculation. In this study, Kc of paddy is estimated by using experimental pots under various water tables treatments. The water table is controlled by using mariotte tube and set at -12 cm, -7 cm, -5 cm, -3 cm, 0 cm, and +2 cm from the soil surface. From the experimental sets, the value Kc is calculated by using modified water balance equation and Kalman Filter. The result shows that water table treatment in paddy farming influences soil moisture ( ) and soil temperature (Tsoil). Soil physic parameter fluctuation due to water table treatment affects the plant growth and potential evapotranspiration. Kc value at each water table treatment is different, and varies with plant growth phase. The average Kc for all water table treatments are 0.77-1.27 (initial season), 0.90-1.11 (crop development), 1.10-1.39 (mid-season), and 1.17-1.40 (late season).
