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.

Farmer Participation in Agricultural Development in Nepal: A Case Study
Nav R. Ghimire


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.

Tree crown bending disorder in tissue culture date palms

C. Sudhersan, Yousif Al-Shayji and S. Jibi Manuel

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. Full Article
