Corn production and plant characteristics response to N fertilization management in dry-land conventional tillage system
Nitrogen (N) application management needs to be refined for low yielding environments under dryland conditions. This 3-yr study examined nitrogen fertilization management effects on corn (Zea mays L.) plant characteristics and grain yield in rain fed environment under conventional tillage system. Nitrogen fertilization management consisted of two timing methods of N application [all N at planti...

متن کاملEffects of residual dry matter on net primary production and plant functional groups in Californian annual grasslands
A five-year experiment tested the response of aboveground net primary production (ANPP) and plant functional groups to manipulations in residual dry matter (RDM), reflecting typical grazing practices in Californian annual grasslands. The RDM treatments were 225, 560, 900 and 5000 kg ha with the latter treatment representing no grazing by livestock. ANPP in autumn, winter and spring showed a str...
