Field and vegetable crops
3.5. Field and vegetable crops
Burt 1906 presented an overview of the general shift from SDI to retrievable tape. It also discusses broadly on the experience of users, the tape materials, installation methods, lying and retrieval methods, practices, equipment and performance. The paper also provides some results of coefficient of variation cv tests in relation to number of uses of the tape. Retrievable tape replaces and SDI for field and vegetable crops Tape retrieval practices have now reached well beyond the theoretical realm. Over the last 10 years, growers of cauliflower, lettuce, celery, and broccoli on the Central Coast of California have generally shifted from SDI to surface retrievable tape. It is expected that drip design and practices will continue to change as new technology and materials are introduced. In recent years, new equipment and techniques developed by farmers and private industry have improved the suitability of surface drip tape as an alternative to subsurface drip irrigation SDI for field crops and vegetable crops in highly mechanized farming. Retrievable drip tape systems now lack many of the disadvantages of SDI, yet provide the advantages typically expected from drip irrigation. This paper provides an overview of the general shift from SDI to retrievable tape. It also discusses broadly on the experience of users, the tape materials, installation methods, lying and retrieval methods, practices, equipment and performance. The paper also provides some results of coefficient of variation cv tests in relation to number of uses of the tape. 4.0. CONCLUSIONS FROM REVIEW OF ABOVE EXPERIENCES The following conclusions can be drawn from the review 4.1. For Fruits In case of fruits such as peaches Little difference was found between trees irrigated by surface and subsurface drip, except that trees irrigated with only one subsurface drip lateral were less vigorous, but not less productive, than trees irrigated by one surface drip lateral, or by two or three subsurface drip laterals. Grapes Incase of King Ruby grapes Comparison of the results between subsurface drip irrigation and surface drip irrigation systems showed that the highest yield and the best quality of grapes were obtained under subsurface drip irrigation system.For Trollinger grapes a drought saving variety Comparison by different methods all yields were found to be unsatisfactory. Must sugar and an acidity were unaffected but cane weight was increased by 22 percent by trickle irrigation and 37 percent by subsoil irrigation.4.2. For Vegetables Tomatoes
