Evaluation of Bulb Yield and Irrigation System (Drip, Furrow and Basin) of onion cultivars

The research has been tested over four long-date onion types for purpose of studying threemethods of irrigation at the Neyshabur Agricultural and Natural sources Research Center for twoyears. The methods of irrigation (drip, furrow and basin) and types of onion (Azarshahr red, Kashanwhite, Neyshabur Red and Neyshabur white) were taken into as main factor in three levels and assub factor in four levels. According to the essence of experiment, the treatments were analyzed in aStrip Plot design based on randomized complete blocks in three repetitions and finally the averageswere benchmarked on basis of Dancan multi-domain test. In studying reciprocal effects of furrowwatering the return of Kashan white onion type comparing to Neyshabur white type watered by plotmethod, had approximately ٤٧% of bulbs yield increment. In studying reciprocal effects of wateringand type of onion, Kashan white onion had ٣٠% more return average in drip watering than plotwatering. In assessment, the lowest return of WUE was of Neyshabur white type watered using plotmethod. WUE in drip watering method was higher than other methods in ٢٨% more than furrowmethod and ٥٢% more than plot method. Yield average in drip watering method was ٧.٢% less thanfurrow and ٢٧% more than plot watering methods
