Abstract

Irrigation is an important factor in agricultural rop planting trickle or drip irrigation method is casier in operational, reguire a lower operational pressure and has a possibility to make from local material. Drip irrigation is a method of water application in form of drip on the soil surface or subsurface. Head loss along lateral is a common problem found in this method caused high variation in emitter discharge. This research aimed to determine emitter head loss along lateral, impact of emitter discharge on operational pressure, pipe diameter and treatment applied on lateral. This research utilized small pipe (1.6 mm in diameter) as emitter. Output discharge more collected and analyzed using complete random design method having 3 level of pressure (4, 6, and 8 psi) and 3 level of lateral diameter (1/3, ¾, and 1 inchi). Head loss calculated using Darcy-Weisbach formula. Result showed a trend of increasing emitter discharge by increasing operational pressure. Increasing in emitter discharge was also found when a larger diameter used in system. Discreasing in head loss was detected when higher pressure a larger lateral used. Emitter uniformity coeffisien, calculated using cristiansen formula, was 91.2 % showing a selected emitter type was acceptable for drip irrigation method.Keywords: emitter, head lose, drip irrigation

Abstract

The effort to develop artificial planting media and technique for more practical irrigation in the cities growing since the area of land available for farming is getting less. A glass house experiment was run to compare the performance of three types of planting media, i.e. 100% rice husk charcoal (RHC), a mixture of RHC (50%) and andosol (50%) and 100% andosol, which was watered in periodical (once a day, once in two days and once in three days respectively) by means of drip irrigation technique. A weekly observation were made on plant growth parameters (plant height, number of leaves, wide, length and the area of leaves) and the shoot length. A daily observation was performed for the room temperature (in the morning, noon and afternoon) and amount of water needed for irrigation. The plant was harvested after 31 days and the yield was determined by gravimetry method for fresh vegetable and in a dry form. The result showed that the use of a mixture between RHC (50%) and 50% andosol watered once ion two days gave the best plant growth and production yield.   Keywords: Planting Media, watering interval, lettuce, drip irrigation
