CONTEXT: Smallholders are responsible for a large share of global palm oil production. Yet, in Indonesia, the main palm oil producing country, smallholders’ yields remain low. Better management practices, including short harvest interval (HI, the number of days between two harvest rounds), could help to raise smallholder yields. However, at present, HI is long in smallholder fields and the drivers underlying this phenomenon are poorly understood.

OBJECTIVE: We explored agronomic, socio-economic, and institutional factors that underlie harvesting practices in independent oil palm smallholder farming systems in Indonesia to assess scope for sustainable intensification through shorter HI and reduced …

Do Wolves Affect White-Tailed Buck Harvest In Northeastern Minnesota?, L. David Mech, Michael E. Nelson

USGS Northern Prairie Wildlife Research Center

We used simple linear regression to analyze 8-23 years of data on a wolf (Canis lupus) population and human harvest of white-tailed deer (Odocoileus virginianus) bucks in northeastern Minnesota to determine any effects of wolves on buck harvesting. Over the long term, wolves accounted for at least 14-22% inter-year variation in buck harvest in the region, but an unknown amount of variation in hunter effort have obscured any more precise estimate. For part of the area with poorest habitat, we found strong relationships (r² = 0.66-0.84) between annual wolf numbers and buck harvests from 1988 …

Ec96-780 Equipment Wheel Spacing For Ridge-Till And No-Till Row Crops, Robert D. Grisso, Paul J. Jasa, Alice J. Jones, Todd A. Peterson

University of Nebraska-Lincoln Extension: Historical Materials

Use of ridge-till and no-till systems has increased dramatically since the early 1980s when ridge-planting equipment and conservation tillage cultivators became readily available. The ridge-till system involves the establishment and annual re-forming of permanent, single-row ridges into which crops are planted year after year. To obtain maximum productivity with the ridge-plant system (and many believe with no-till systems), all wheel traffic should be confined to interrows. Wheel traffic on ridges can alter the ridge profile and condition of crop residue. Ridge deformation or excessive tire sinkage can affect subsequent planter performance, crop emergence and the overall productivity of both ridge-till …

G78-426 Popcorn Production, Nora D'Croz-Mason, Richard P. Waldren

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses seed selection, soil requirements, production management, pest control, marketing and sale of popcorn.

Commercial popcorn production in the United States has always been concentrated in the Corn Belt. Iowa was the largest popcorn producer until the mid 1940s. As hybrids replaced open-pollinated varieties, popcorn production shifted to Illinois then to Indiana. During the mid 1970s popcorn production moved west, and in 1977 Nebraska became the nation's largest producer. During the 1980s popcorn acreage has fluctuated among states, but Nebraska often has had the nation's highest yield because 85 percent of its crop is irrigated.
