In this study, the cutting force and energy requirement of corn (Zea mays L.) stalk at different internodes (diameter), from bottom to top internode positions for Pionner 2105, Pioner 1570, KWS MAY 75 varieties, were determined. The mean diameter varied between 11.28-19.00 mm bottom. Also, cob breakout requirements determined these varieties. According test results, varieties found statisticall...

Fall armyworm, Spodoptera frugiperda (J.E. Smith), and corn earworm, Helicoverpa zea (Boddie), perennially cause leaf and ear damage to corn, Zea mays L., in the southeastern United States. Transgenic Bacillus thuringiensis (Bt) hybrids with the Bt11, MON810, or 176 events expressing the Cry1Ab insecticidal endotoxin from were evaluated for control fall armyworm and corn earworm at seven locati...

Corn stalk, an agricultural waste, was valorized by the production of cellulose nanofibers (CNF), which were tested for improving recycled paper properties. CNF from eucalyptus kraft pulp (E-CNF) was used as a reference. Addition of 0.5% wt. CNF produced from corn organosolv pulp (C-CNF) to recycled paper increased the tensile index by 20%, whereas the same improvement with E-CNF was achieved a...

Corn rootworm larvae consume maize root tissues, thus negatively impacting plant physiology and function (Riedell 1990; Hou et al. 1997; Riedell and Reese 1999), and impeding harvesting due to stalk lodging (Sutter et al. 1990). Ultimately, larval rootworm feeding reduces yield (Sutter et al. 1990; Spike and Tollefson 1991), and can cause significant economic losses (Metcalf 1986). Pesticides, ...
