Effect of saline irrigation water on growth and yields of onion (Allium cepa L.) varieties

Abstract

A pot experiment was conducted at Department of Agricultural Chemistry and Soil Science, College of Agriculture, Junagadh Agricultural University, Junagadh to assess the "Effect Of Saline Irrigation Water On Growth, Nutrients Composition And Yield Of Onion (Allium Cepa L.) Varieties" during the winter, season of 2017-18. The pot experiment comprised four levels of salinity viz., <2.0, 4.0, 6.0 and 8.0 dS m-1 and five different varieties viz., V1-GJWO-3, V2-GJRO-11, V3-Talaj red, V4-Pilli patti and V5-PWF-131 in Factorial Completely Randomized Design with replicated three times. The experimental result revealed that the growth, yield and yield attribute, quality parameters, biochemical parameters, nutrient content and nutrient uptake were significantly influenced by the different varieties of onion. The highest plant height (49.33 cm), fresh straw yield (37.03 g), fresh weight of bulb (39.21 g), volume of bulb (25.67 cm 3), bulb yield (133.33 g/pot) and quality parameters viz., neck thickness and TSS among different tested varieties of onion.
