Abstract

Various agronomic aspects of peanut (Arachis hypogaea L.) culture in southern Ontario were investigated. Experiments conducted included cultivar trials, row width and population studies, planting date and digging date studies, herbicide screening, and studies on rate and time of gypsum application. The results indicated that Spanish and Valencia types could produce yields of mature seed of commercial order; Virginia and Runner types produced low yields because of growing season limitations. Closer seed spacing resulted in higher yields than wider spacings at both early and late May plantings. Seeding rates between 180 000 and 330 000 plants per hectare produced higher pod yields than did lower or higher populations. Digging in late September resulted in higher yields than either earlier digging or digging subsequent to a killing frost. The application of gypsum at rates up to 1792 kg/ha at the early bloom stage or in split application (early bloom plus 2 wk later) did not increase yields. Several herbicide treatments resulted in yields equal to those harvested from the hand-weeded check. In both 1973 and 1974 pod yields of specific treatments yielded in excess of 3000 kg/ha
