    Irrigation and Tillage Effects on Peanut Yield in Virginia¹

    Authors: , , ,

Abstract

During crop years 19801983, a field study was conducted in southeastern Virginia on a Norfolk loamy fine sand soil to evaluate the effect of irrigation, underrow ripping, and seedbed preparation methods on peanut yields. The seedbeds were prepared conventionally (flat), with a rotary tiller and bed shaper, with a disk bedder, and with a rolling cultivator. Irrigation increased peanut yield only for crop year 1980 peanuts when there was a severe drought. Irrigation decreased yields for the other 3 years when rainfall was near normal. Some of the decrease in yields with irrigation can be attributed to an increase in the severity of several diseases including leafspot, pod rot, and Sclerotinia blight.
