Response of the maize-sesame-pigeon pea association to N, P, and K at La Máquina, Guatemala
IPNI-2014-GTM-7
The residual effects on maize and sesame of P and K applications made in 2014 were studied in 2015. No tillage was used to reduce the interactions between the two nutrients and the soil. In maize, significant positive effects on grain yield were determined from additions of P, but not from K applications, whereas sesame yields did not differ statistically with either P or K application timing or rates.

Interpretive Summary
| 2015 | The residual effects on maize and sesame of P and K applications made in 2014 were studied in 2015. No tillage was used to reduce the interactions between the two nutrients and the soil. In maize, significant positive effects on grain yield were determined from additions of P, but not from K applications, whereas sesame yields did not differ statistically with either P or K application timing or rates. |
| 2014 | La Máquina is an important agricultural area in the Southwestern coast of Guatemala. Maize is usually grown in association with sesame, and increasingly with pigeon pea. This project was started in 2014 at the Semilla Nueva Experiment Station to determine the response of maize, sesame and pigeon pea to N, P and K. The soil had pH of 6. 2, 2. 6% organic matter, 10 ppm Mehlich-3 P, a cation exchange capacity of 12. 3 cmol/kg, 0. 39 cmol/kg K, 8. 31 cmol/kg Ca, 3. |
