Response of Two Maize Cultivars to Potassium in Cintalapa

The objective of the study was to determine the response of an open pollinated variety and a hybrid to K supplied by two sources and at four rates.

IPNI-2013-MEX-53

The objective of this study is to determine the responses of an open pollinated variety and a hybrid of maize to K fertilizer applied using two sources and at four rates. The study was conducted in a farmer’s field in Cintalapa, Chiapas, Mexico on a sandy clay loam soil (pH 5. 5, 2. 4% organic matter, 51 ppm Bray 1-P, 48 ppm available K, 1,214 ppm Ca, 213 ppm Mg, 18 ppm Na, 0,7 ppm Zn, 32 ppm Mn, 2 ppm Cu, and 0,2 ppm B).
