Response of White Spanish Peanuts to Applied Sulphur, Inoculation and Captan Spraying in the Wet Lowlands of New Guinea.

Abstract

White Spanish peanuts were sown at Bubia, near Lae with applications of 0, 25, 50 and 100 lb per acre of elemental sulphur. At the same time inoculation and spraying treatments were imposed. There were very highly significant increases in yields of kernels to the applied sulphur up to 50 lb per acre. Production of shell increased only slightly. Part of the increased yield can be explained by the significant increase in nut size on sulfur-treated plots. One hundred pounds of sulphur per acre gave a slightly lower yield than 50 lb per acre. Responses to inoculation and captan, which both appeared to cause a slight reduction in yield, were not significant.
