Design of micro irrigation systems

The conventional method of Tomato cultivation under furrow irrigation needs a paradigm shift towards modern irrigation systems due to water scarcity. Drip irrigation method distributes water to the field using the pipe network and transforms it from the pipe network of the plant by emitters. In spite of the advantages of drip irrigation method, the traditional network of drip irrigation method has many problems. Hydraulic design seems to be only one of the minor factors of the evaluation of overall uniformity of a micro-irrigation system.

The study was undertaken in Southern parts of Karnataka to evaluate and to assess the design and performance of the different make drip irrigation systems in Greenhouses. Information about farmers and other details were collected from different dealers of respective company makes. The three greenhouses from each companies, which were selected for the study. The results on the design indicated that all the greenhouses having good operating system, but the six of them were not capable to operate the system results in poor performance.

The study was conducted at Technology Park (Plasticulture Farm) of CTAE, Udaipur, Rajasthan to evaluate performance of automated and conventional drip system for okra crop during year 2019. The Uniformity Coefficient (CU), Distribution Characteristic (DC) and Emission Uniformity (EU) were found to be highest at the head and decreases with increase in distance along the lateral for both irrigation systems. It was found that the average values of all evaluation parameters except DC, were found to be highest for automated drip system.

A field trial was conducted to standardize water and nutrient requirement for raising tree species in High Density Plantation and to study the impact of balanced fertilization on growth and physiology of tree species. The experiment was laid out in split plot design comprised of main plot with irrigation treatment and sub plot with fertilizer levels. Water requirement of the tree plantation was calculated using the pan evaporation (PE) data. Fertigation schedule consisted of humic acid (62.
