      <ArticleTitle>Effect of Depth of Subsurface Drip and Irrigation Scheduling in Summer Okra
      <Abstract>A study was conducted how different emitter rates with SDI affected the moisture distribution in clay loam soil of coastal belt of Gujarat. In order to find optimum emitter rate with various depths of emission on a soil filled cube shaped container as physical laboratory model and field conditions which was found to be 4 lh-1. On summer okra (Abelmoschus esculentus L. Moench.) crop field experiments were conducted with 4 lh-1 emitter rate (during 2013-14 and 2014-15) in sandy clay loam soil of KVK farm, JAU, Porbandar, Gujarat to assess optimum irrigation regime and depth of emission based on the yield performance. The Experiment was executed with three irrigation regimes (0.6, 0.8 and 01.0 IW/ CPE) and depth of lateral placements (0, 0.10, 0.15 and 0.20 m below the soil surface. The data of green pod yield with applied water was recorded during experiment and subjected to split plot design for analysis. It was found that significantly higher yield (15.46 tha-1) was obtained with 1.0 IW/ CPE level than other irrigation regime. Pod yield in 15 cm depths of SDI laterals was found significantly higher than that under other lateral depths. The water use efficiency (25.01 kg/ ha-mm) was also higher with 0.15 m placement depth of lateral. The trend line of production function of emission depth (yield –emitter depth) is fitted in quadratic form (R2=0.636). If the depth at which okra yield was found to be maximum taken as the correct depth for placement of drip tape in the soil that is 0.15 m. But the optimum value of depth of emitter placement is computed using production function of depth, it is found to be 0.119 m for maximum production.</Abstract>
