Mahatma Phule Krishi VidyapeethRahuri, Maharashtra, India
Efficiently manage irrigation for brinjal cultivation, we explored the use of a diffuser irrigation system based on a climatological approach, particularly Evapotranspiration, for replenishing water needs. Experiment was carried out the instructional farm of the Irrigation and Drainage Engineering Department at Mahatma Phule Krishi Vidyapeeth Rahuri. The net irrigation water applied treatment (T1) was highest i.e., 94 liters per plant. Similarly, The plant height, and yield observed superior in treatment (T1), due to net quantity of water applied was sufficient. The efficiency of irrigation water use was at its peak in treatment T4.
⓿ Seasonal water requirement of brinjal found highest in 100 % ETc with diffuser per plant was 94 litre/plant.
⓿ Highest water saving registered in 40% ETc treatment was 60 %.
⓿ 100 % ETc treatment recorded 199.54 tone ha−1 highest brinjal yield.
⓿ Water use efficiency observed highest in 40 % ETc treatment was 9.03 tone ha−1 cm−1
⓿ Number of branches recorded highest in 100 % ETc treatment in entire growth period.
⓿ Plant height recorded highest in 100 % ETc treatment in entire growth period.
