Abstract

The research objective was to determine the effect of soil water level differences, porosity and semi permeable layer thickness for subsurface irrigation on chilly (Capsicum annum) crop growth.  It used split plot design with two factors of treatment and three replications for each treatment factor.  The first factor was soil water level height consisting of 4 cm, 8 cm and 12 cm as a main plot.  The second factor was combination of thickness (t) and sand (s) as well as clay (c) composition as subplot consisting of A1B1 (1 cm, 30%, 70%), A1B2 (1 cm, 40%, 60%), A1B3 (1 cm, 50%, 50%), A2B1 (1,5 cm, 30%, 70%), A2B2 (1,5 cm, 40%, 60%), A2B3 (1,5 cm, 50%, 50%). The observed parameters were water content (%), climatic data, crop length increment (cm), leaves number, flower shoots number, fruits number and crop dry matter weight (g). The results showed that the highest crop grwoth was found on 8 cm soil water level and A2B2 treatment with average value of 106.33 cm and the lowest one was found on 12 cm soil water level and A2B1 treatment with average value of 70.00 cm, respectively. The highest yield was found on 8 cm soil water level and A1B2 treatment with weight of 373.488 g. Treatments of 12 cm soil water level and A1B3 as well as A2B3 had produced zero yield. Semi permeable layer of B2 composition was the best water delivery for chilly crops, whereas 8 cm soil water level was the best water height for chilly crops.  Keywords: Soil water level, thickness and composition of sand and clay.

Abstract

The objective of this research was to find out the best combination of nozzle diameter and height of watering of the soil compaction by considering of irrigation spraying efficiency which is best to be determined to value Coefficient of Uniformity and Distribution of Uniformity. This research was done by applying the water to irrigation area in time needed to each treatment in order to soil compaction. The research used description method followed by tabulation and graphical presentations with two factors (A and B) and two replications. Factor A was the nozzle diameter (1 mm, 2 mm, 3 mm) and factor B was the height of watering (1 m, 1½ m, 2 m). The observed data were include water content (%), bulk density (g/cm3), soil compaction (%), coefficient of uniformity (%) and distribution of uniformity (%). The result showed that the highest value of water content was 69.66% (D3T1) which is the treatment with combination of nozzle diameter by 3 mm and height of watering by 1 m and the lowest of water content was 46.20% (D1T3) which is the treatment with combination of nozzle diameter by 1 mm and height of watering by 2 m. The treatment with combination of nozzle diameter 3 mm and height of watering by 2 m (D3T3), was the best treatment with bulk density 1.338 g/cm3, porosity 31,53%, the soil compaction 26.001%, coefficient of uniformity 80.51%, distribution of uniformity 74.14%. In reality, combination between of nozzle diameter and height of water did not have a value of Uniformity Coefficient (?85%) and Uniformity Distribution (?75%).Keywords: Nozzle, Sprinkler irrigation, Soil compaction, Uniformity Coefficient , Uniformity Distribution
