To Compare the Utilization of Fertilizer through Drip, Micro Sprinkler and Conventional (i.e. Check Basin) Irrigation Methods in Litchi Plants Inter – Cropped with Garlic and Onion- A Case Study

The research work entitled “To compare the utilization of fertilizer through drip, micro sprinkler and conventional (i.e. check basin) irrigation methods in litchi plants inter – cropped with Garlic and Onion.” was carried out under three main treatments on Irrigation methods namely; drip, micro sprinkler and traditional irrigation method (Check basin), three sub main treatments. i.e. without intercrop and inter-cropped with garlic and onion crops, with three replications. Based on the harvested database, it was found that the growth parameters of litchi plants were significantly greater in case of drip Irrigation along with 100% fertigation, followed by micro-sprinkler irrigation and traditional method. The lowest response was observed when irrigation was applied through drip without fertigation. The fertilizer use in respect of plant growth was evaluated to be maximum i.e.,60.50cm/quintal in treatment T2 (application of irrigation and fertigation through drip irrigation system) and lowest 50.50cm/quintal in T4 (application of irrigation and fertigation through traditional method). The maximum benefit – cost ratio was estimated to the tune of 5.20 for garlic crop and 6.30 for Onion crop under treatment T3 (application of irrigation and fertigation through micro irrigation system). Phenological growth of litchi plants was not significant. The fertilizer use in respect of plant growth was evaluated to be maximum i.e.,60.50cm/quintal in treatment T2 (application of irrigation and fertigation through drip irrigation system) and lowest 50.50 cm/quintal in T4 (application of irrigation and fertigation through traditional method). The maximum benefit – cost ratio was estimated to the tune of 5.20 for garlic crop and 6.30 for Onion crop under treatment T3 (application of irrigation and fertigation through micro + irrigation system).
