Cucumber is an important cucurbitaceous crop, which play an important role in our diet, due to its high nutritive value. The area and productivity of cucumber is very low, hence to maximize the production per unit of water use, adequate and timely supply of water is crucial one. Protected cultivation is frequently adopted for obtaining higher yield per unit area. The present investigation aimed with specific objectives to work out the water requirement of cucumber under shade net house, to study yield response of cucumber to different shading percentage of shade net and fertigation, to...

As water for irrigation is a scare resource, its optimization is fundamental to water resource use. It permits better utilization of all other production factors and thus leads to increased yields per unit area and time. Irrigation scheduling is the systematic method by which producer can decide on when to irrigate and how much water to apply. In climatologically approaches, irrigation is scheduled on IW/CPE ratio. In IW/CPE approach, known amount of irrigation water is applied when cumulative pan evaporation reaches predetermined level. The experiment was conducted in randomized block design...

The mini sprinkler method of irrigation is recently introduced pressurized irrigation method. The basic objective of mini sprinkler is to simulate rainfall and to apply uniform water to crop. The performance of mini-sprinkler is judged by its uniformity of distribution of water which depends on the proper, efficient and economic design of the system. The important parameter in mini sprinkler irrigation is to optimize the spacing between mini sprinklers for different crops which influences the discharge, uniformity and cost. Considering the aspects and complexity in the management of mini...
