Effectiveness of tomato plant growth with drip irrigation techniques in drylands

Dry land with low rainfall results in minimal availability of irrigation water. However, the lack of irrigation water is not an obstacle in cultivation if the right, effective and efficient irrigation method is applied, namely drip irrigation. This study aims to see the effect of applying drip irrigation techniques with different water discharge treatments on tomato plant growth. This research was conducted in Batu Putik Village, East Lombok Regency from August 12, 2020 to September 20, 2020. This research method uses experimental methods by conducting direct experiments in the field. This study used a Completely Randomized Design (CRD) with 3 treatments 4 times repeated so that 12 experimental units were obtained. Each treatment was P1 with a 90° tap slope discharge, P2 with a 45° tap slope discharge, and P3 with a 15° tap slope discharge. The research data were analyzed using ANOVA. The results of the drip irrigation technique design performance test showed an average uniformity coefficient percentage of 94% in all treatments. The results of this test provide an insignificant effect on plant height, stem diameter, and number of leaves of tomato plants. So this insignificant result shows that the application in the field in relation to water efficiency should use P1 with less water distribution but gives the same effect as P2, and P3 on tomato plant growth. While in wet and dry stems, there is a significant effect between treatments.
