The total factor productivity index for u.s. wheat was 1.5% per year between 1974 and 1983. The conservation tillage productivity index for u.s. wheat was about 1.1% per year during this time period, or about 75% of the T.F.P. North Dakota and Washington were equal in competitive advantage in...

Conservation tillage was used on more than 99 million acres in 1994, about 35 percent of U.S. planted crop area. Five years earlier, the total conservation-tilled acreage was 72 million. Besides conserving soil, crop residue management practices also cut production costs on many farms....

We develop a real option model of the irreversible native grassland conversion decision. Upon plowing, native grassland can be followed by either a permanent cropping system or a system in which land is put under cropping (respectively, grazing) whenever crop prices are high (respectively, low)....

Because of payoff uncertainties combined with risk aversion and/or real options, farmers may demand a premium in order to adopt conservation tillage practices, over and above the compensation for the expected profit losses (if any). We propose a method of directly estimating the financial...

This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region. This research uses stochastic efficiency...

Agricultural Resource Management Survey (ARMS) data for 2003 were used to estimate two binary logit models for two definitions of genetically modified (GM) cottonseed adoption. Results indicate conservation tillage did not positively affect adoption of GM cotton with either of these definitions,...

A study of irrigated strip-till soybean production compared gross margins over nematicide expense for a continuous triticale-soybean system versus a two-year rotation system alternating triticale-soybean with triticale-cotton. Half of the replicated plots under each system received nematicide...

In the wake of the resource constraints for external farm inputs faced by farmers in developing countries, sustainable agriculture that relies on renewable local or farm resources presents desirable options for enhancing agricultural productivity. In this study, we used plot-level data from the...

In this review, we present the recent developments and future prospects of improving nitrogen use efficiency (NUE) in crops using various complementary approaches. These include conventional breeding and molecular genetics, in addition to alternative farming techniques based on no-till...

The following review is an financial assessment of an Australian Centre for International Agricultural Research (ACIAR) conservation tillage and controlled traffic research project which was conducted in China (for the conservation tillage component) and Australia (for the controlled traffic...
