Abstract

ABSTRACTThe operation of groundwater irrigation requires additional cost for fuel and pump operators.    This,  therefore, require  careful cost  calculation in  order  to  obtain expected income.  For this purpose, the research was conducted to optimize the usage of irrigation water from one of wells at Watulawu, Pondidaha, to determine the most profitable crop species and cropping system.  The optimization was conducted using a linier program with QSB (Quantitative System Business) software, with the objective function was the maximum profit  of  farming  and  the  limiting  function  was  the  availability of  irrigation  water  and planting  size.  Out  of  optimized  crop  species  (rice,  maize,  groundnut,  and  soybean), groundnut and rice were the profitable crops.   Planting size for both species was varied during each  planting season, depending on  crop  water requirement and  rainfall.    Early cropping on March required less irrigation water than early cropping on February Keywords : Groundwater irrigation, QBS Software

Abstract

In order to develop soybean plants, the availability of water in the form of soil moisture is one of the factors that give a very important message. Water supply is usually obtained from rainwater, so the arrangement of cropping pattern often follows the pattern of rainfall distribution that occurs. Preparation of water balance is intended to increase the productivity of dry land through the determination of pattern and planting schedule in accordance with groundwater availability. The water balance analysis using climate data series includes monthly rainfall and air temperature. Climate data obtained from Climatology Station Wolter Monginsidi Kendari Southeast Sulawesi. The opportunity for rainfall is exceeded and the water balance is analyzed using statistical methods. The results show that the soil moisture conditions are available for the crops for 8 months, ie from December 10 daily 2 to July 10 daily 2. while the water deficit in August to November (during dry season). Thus the cultivation can be done for 8 months ie when a surplus of water.

Abstract

The aim of this research was to know the effect of urea fertilizer on growth and yield  of  mustard  plant.  This  research  was  carried  out  at  the  Experimental  farm  of Agriculture Faculty, Haluoleo University, from October to November 2012. This research was carried out using completely randomized block design, that consisted of 6 treatments namely: without Urea fertilizer (U0), 25 kg ha-1 equals to 1.6 g plot1 of urea fertilizer (U25), 50 kg ha-1 equals to 3,2 g plot-1  of urea fertilizer (U50), 75 kg ha-1equals to 4,8 g plot-1of urea fertilizer (U75), 100 kg ha-1 equals to 6,4 g plot-1 of urea fertilizer (U100),125 kg ha-1 equals to 8 g plot-1 of urea fertilizer (U125) . Each treatment was repeated 3 times which resulted in 18 experiment units. The experiment data were analyzed using analysis of variance method and then followed by Honest Significantly Difference Test. The result of the research showed that the application of various dosages of urea fertilizer has an effect on the growth and yield of mustard plant. The application of urea fertilizer to mustard plant effected plant height, leaf area at the age of 21 and 28 days after planting, dry weight of root, dry weight of leaves and relative growth rate. However, the application of urea fertilizer has no effect on the number of leaves, leaf area at the age of 14 days after planting, leaf fresh weight, and the root fresh weight of mustard plant. An increase in the dosages of Urea fertilizer was followed by an increase in the growth and production of mustard plant. 125 kg ha-1 urea fertilizer increased growth and production of mustard plant a lot higher compared to other of urea fertilizer with a production yield of 10 ton ha-1. Keywords: mustard plant, urea
