Onion Fertility Evaluation Under Different Levels of Salt Stress, Safford Agricultural Center 1986
MetadataShow full item record
AbstractYield data were taken with a long -day onion variety, using different levels of nitrogen, phosphorous and potassium and at two different levels of soluble salts in the soil. Yields of the plots with additional fertilizer applied did not vary statistically from the check plot, which had 79 lbs/ac of nitrogen and 66 lbs/ac of P205. A correlation was found, however, between the electrical conductivity of a saturated paste extract from the soil and the yield of onions. A loss of 205 sacks (50 lbs /sack) of onions per acre are lost for each unit increase in soil conductivity.
