Modified Design for Drip Irrigation System Using Waste Materials and Rainwater to Improve Crop Productivity (an Innovative Research) by TESDA Regional Training Center - CaLaBaRZon MGD Hiwatig, JM Cabaces. and AM Padullo Abstract A modified gravity-fed drip irrigation system design has been developed for used in raised garden beds and other small-scale crop production when properly designed, maintained and operated—can be a production asset for a small farm. Using drip irrigation for profitable vegetable production requires an understanding of several basic technical engineering, horticultural concepts and standard manufacturing classes. The scope of the project includes the tank support system, waste materials and using rainwater as a supply to the piping system maximizing its potential. Drip irrigation is an efficient method of providing irrigation water directly into soil at the root zone of plants and thus, minimizes conventional losses such as deep percolation, runoff and soil erosion. It also permits the utilization of fertilizers and other water-soluble materials along with irrigation water resulting in higher yields and betterquality produce. This article illustrates the modification drip irrigation system with eco-friendly design to efficiently deliver water to crop that may result on increases the yield of small-scale farmers. The researchers encourage the public and private sector in the adaptation of the innovation to the local needs and provides historical analysis and perspective in assessing technology impact. The estimated increase of crop production is from 16-48%, depending on the crop and location, and may increase the income of small-scale farmers by 2.6-7.4% annually. On whole, the goals of this publication serves as complete outline of the project and includes design and research, concept design processes, explanation of chosen design, and the manufacturing processes and testing results. 1.

Findings/Results/Discussion Statistical analysis specified that the maximum values of water productivity and complete net return for farmers were discovered under the modified design (3). The result proved that, emotion uniformity will be increased from 74% : 75% : 99,6% throw out design (1) , design (2) and modified design (3), respectively as show in Fig. (3). Furthermore, the averages of emitter discharge along laterals L/h with modified design (3) were stable from start to end but with design (2) the averages were decrease 6.
