Última AERIAL AND GROUND APPLICATION OF FUNGICIDE IN CORN SECOND CROP ON DISEASES CONTROL REA Menechini,Wagner; Maggi,Marcio F.; Jadoski,Sidnei O.; Leite,Carla D.; Camicia,Ricardo da M.. ABSTRACT The aim was to evaluate the diseases severity on corn second crop. The research was conducted on the agricultural year of 2013 and 2014, evaluating the application quality over the fungicide spraying. The hybrid used was PIONEER 30k75 BT HERCULEX, evaluating the diseases severity previously and after the fungicide spraying, spray deposition on the culture and productivity. The aerial application was carried out with solution volume of 7.5, 13.5, 20 and 30.3 L ha-1, using automatic rotating nozzles, and the ground application with 90, 110, 130 and 150 L ha-1, uniform flat spray tips. As control a non-fungicide treatment was used. The aerial and soil treatment showed diseases control from the corn crop, being the biggest cover of drops acquired at...

Acta Agron. (Palmira) Pedroza-Sandoval,Aurelio; Yáñez-Chávez,Luis Gerardo; Sánchez-Cohen,Ignacio; Samaniego-Gaxiola,José Alfredo; Trejo-Calzada,Ricardo. Abstract The increase in the incidence and intensity of drought caused by climate change is a critical factor in agricultural production in some regions of the world. Dry lands are often severely affected by water shortages caused by low rainfall. This study evaluated the effect of compost and hydrogel used to retain soil moisture on photosynthetic activity and forage corn production. The experiment was designed as a randomized block with a split plot design; the main plots were the hydrogel application rates (0, 12.5 and 25 kg ha-1), and the subplots were the compost application rates (0 and 20 t ha-1). Photosynthetic activity increased by 20.2-28.0% when the hydrogel was applied at rates of 12.5 and 25 kg ha-1, respectively, compared with the control. As...
