Abstract

Flooding and overflowing on horticultural plant especially for tomato plants cause failure of vegetative and generative growth.The extent to which tomato plants tolerance if grown in andosol soil to overflowing and flooding need to be studied. This research was aimed to examine the Effect of Overflowing length on the water quality and soil physical properties of andosol together with tomatoe plant growth. The result of the research showed that evapotranspiration at beginning of growth of 15 days since plant (dsp) was 1,79 mm/day, on active growth (16-45 dsp) was 3,45 mm/day, on maximum growth (46-75 dsp) was 3,45 mm/day and the end of growth (>75 dsp) was 2,41 mm/day. Water quality that unfavorable effect towards the growth of tomato plants for 2 days in overflowed conditions and overflowed until the plants death was dissolved oxygen. Dissolved oxygen for 2 days in overflowed conditions was 1,98 ppm and for overflowed conditions until the plants death was 1,68 ppm.Soil Physical properties that unfavorable effect towards the growth of tomato plants for all conditions was soil temprature. Soil temprature for 2 days in overflowed conditions was 27,83oC, for overflowed conditions until the plants death was 28,25oC and for spacey capacity conditions was 27,85oC. For 2 days in overflowed conditions the soil salinity was over the restriction limit which was 5,8 mS/cm. Blossom production of tomato plant on spacey capacity conditions was 27 blossom/plant, for 2 days in overflowed conditions was 17 blossom/plant and for overflowed conditions until the plants death has not blossom.

Abstract

One way to overcome erosion is using vegetative methods, where its influence can be manifested by the C factor. The best C factors used in determining the amount of erosion is the value of C in the local area. This study was aimed to determine the value of string bean and cucumber crop factors on the Andepts soil during April to August 2013 using the method of small plots and USLE. Parameters used in determining the C factor were the amount of erosion, the allowable erosion rate, and the erosion hazard level. The results showed that the amount of erosion on land without a crop was 0,46 ton (ha.year)-1,on cucumber land was 0,41 ton (ha.year)-1, on string bean land was 0,31 ton (ha.year)-1. The amount of allowable erosion rate was 31 ton (ha.year)-1. While erosion hazard rate on land without a crop was 0,014; on cucumber land was 0,013 and on string bean land was 0,010 which include in low category. The value of string bean crop factor using rainfall research data for 4 months and 10 years data was 0,685 and 0,690 respectively. The value of cucumber crop factor using rainfall research data for 4 months and 10 years data was 0,902 and 0,911 respectively Keywords : Andepts, C factor, Erosion, Kwala Bekala USU.

Abstract

The need of water on the field of durian lingga village was channeled through tertiary canal that made from soil. This can affect the lossing of water. This study was aimed to examine the tertiary irrigation channel in that area. The parameters measured were the physical of soil properties, the discharge channel, the efficiency of the distribution, water loss, flow velocity, slope and size of the channel. The results of the research showed the efficiency of the distribution on line 1 at a distance of 120 m was 63.12% and channel 2 at a distance of 90 m was 66.46%. The efficiency of channeling at a same distance (90 m) with the assumption of losing the water on every meters was the same, was 78.87% on channel 1 and 66.46% on channel 2. The average flow velocity was smaller than the critical speed so that precipitation happened, there for redesign of the channel dimensions was needed. The result of the best design of tertiary channel dimensions for the channel 1 was width of the channel (B) of 0.704 m and depth (D) of 0.352 m with a slope of 0.032%, while for channel 2 the width of the channel (B) was 0.844 m and the depth (D) was 0.422 m with a slope 0.02%.

Abstract

Seepage is one of the causes of lost of water in irrigation channel. It is difficult to measure the seepage directly on the field. Therefore there should be a model or equation to determine the channel seepage that is the first stage through laboratory scale. This research was done to analyze the seepage coefficient of trapezoidal cross-section irrigation channel on Latosol soil through laboratory scale. The water balance component which was measured were evaporation, percolation and seepage through channel wall. The research showed that the coefficient of seepage was about 3732,48 to 5339,52 mm/day. The evaporation  value was 1,33 mm/day and channel percolation was 376,41mm/day. Key Word : coefficient of seepage, irrigation channel, trapezoidal cross-section, Latosol soil, laboratory scale.

This research was purposed to study water distribution in Inceptisol soil planted with soybean at 100%, 80%, 60% field capacity and its effect on soybean plant’s production. The parameters observed were the characteristic of the soil physics, field capacity, evapotranspiration, water distribution, dry weight of soybean plant and pods weight.The results showed that Inceptisol soil had sandy clay loam texture. The highest porosity was found at 6-10 cm depth i.e. 63,06%. The lowest porosity was found at 0-5cm depth i.e. 54,23%. Water field capacity was 47,7%(dry basis). Soybean plant evapotranspiration at middle growth phase was 1,97 mm/day and the last growth phase was 1,58 mm/day. The highest water level was found at 6-10 cm depth i.e. 20,58-32,49% (dry basis). The lowest water level was found at  0-5 cm depth i.e. 20,34-26,63% (dry basis). The dry weight of soybean plant at the middle growth phase at 100% field capacity was 16,51 g, at the last growth phase was 14,89 g and pods weight was 13,20 g.
