Based on the 2016-2017 farm survey data, this study examines technical efficiency in the production of wheat, rice, and maize in Punjab province in Pakistan. Technical efficiency, under varying returns to scale, in wheat farming averaged 0.65; in rice, it averaged 0.74, and in the case of maize,...

This study examined the effects of research-based recommended cereal production practices on the technical efficiency of farm households based on household-level data generated from questionnaire surveys, focus group discussions, and key informant interviews. The technical efficiency scores were...

Starting in the 1930s, commercial hybrid corn seeds rapidly replaced the once predominant open-pollinated varieties planted by farmers. By the mid-1950s almost all corn grown in the United States was of hybrid varieties. Observers have argued that the drought tolerant qualities of these hybrids...

The increasing population, water scarcity, and labor cost demand more high-yield, water-saving, and efficient maize production. Grain mechanical harvesting, the quality of which is mainly influenced by grain moisture content, can improve the efficiency and decrease the harvest cost of maize...

An extraordinary high-strength dilute Mg-0.8Al-0.1Ca-0.6Mn (wt. %) alloy wire was successfully developed by hot drawing, which exhibits high tensile yield strength of 394 MPa, ultimate tensile strength of 431 MPa and moderate elongation to failure of 6.0%. The high strength was mainly attributed...

A novel mathematical model based on the recently proposed Changing Grain Size Model (CGSM) was developed to take into account the grain size distribution, the sintering effect, and the grains overlapping phenomenon in the particle during the carbonation and calcination of pure limestone. The...
