Economics of hauling dairy slurry and its value in Wisconsin corn grain
systems
G.R. Sanford, J.L. Posner, and G.L. Hadley
Abstract
To evaluate the potential of using dairy slurry for corn (Zea
mays L.) production in Wisconsin grain systems, custom manure hauler
bids were combined with corn production expenses to develop enterprise
budgets in which slurry provided corn nutrient needs. A scenario was
developed in which a recipient grain farmer shares manure hauling costs
with the dairy farmer supplying the slurry. Results showed that by
sharing manure hauling expenses, profitable hauling distances more than
doubled (from 3.2 to 7.6 km). These results suggest that grain and dairy
farmers could enter into beneficial manure contracts having both
economic and nutrient conservation advantages.

Abstract
This study examined the government’s aims in promoting
farmer participation in Nepal and analyzed the experiences of farmers in
an agricultural development program. Findings suggest that government
policy stresses close coordination among research, extension and farmers
but in practice farmers’ needs and priorities were not considered in
program design. Extension staff directed farmer participation in the
program mainly to generate the data for program reporting, while farmers
often participated mainly for the ‘incentives’ offered. There is a need
for strong interaction and coordination between participatory
practitioners and farmers on setting the aims and type of participation
in agricultural development.

Abstract
Date
palms were propagated in large numbers clonally through tissue culture
technology. Tissue culture derived date palm cultivars planted in the
KISR tissue culture orchard showed crown bending at the fruiting stage.
The affected palms on dissection in the field showed the insect attack
and secondary infection by fungi on the wound. The larvae collected from
the infected tree were reared inside the laboratory for the
identification of the insect. The insect was identified as Arenipses
sabella. The infected trees were recovered after the treatment with
insecticide and fungicide solutions at the right time prior to the
complete damage of the shoot meristem. The findings of the study could
solve the mystery behind the date palm tree crown bending and the
confusion over the tissue culture method of propagation.
