Response of maize and sesame in relay cropping to phosphorus and potassium in La Maquina, Guatemala

IPNI-2015-GTM-11

A study was conducted at Semilla Nueva’s La Maquina Research Station in Guatemala on the response of maize and sesame to P and K. Three application rates of P (0, 100, and 200 kg P2O5/ha) and three of K (0, 100, and 200 kg K2O/ha) were combined in a complete factorial arrangement, with three replications. Maize grain (14%) yields were very low when no P was applied, regardless of the K rate: 390, 310, and 805 kg/ha for 0 P2O5+0 K2O, 0 P2O5+100 K2O, and 0 P2O5+200 K2O kg/ha, respectively. Read more
