Studies were conducted in 1989 and 1990 at Lane, Oklahoma, to evaluate the economic benefits of managing lepidopterous pests of fresh-market cabbage using Bacillus thuringiensis Berliner var. kurstaki, or a pyrethroid insecticide in combination with an economic threshold based on larval density. Marketable cabbage yield and percent head damage were not significantly different among plots spraye...

Prior research found that residual income (RI) is not as informative about stock returns as net income (NI), despite theory that demonstrates the role of residual income in valuation and a long history support for RI among practitioners. We replicate these tests and find similar results. We then consider an alternate perspective of viewing NI and RI not as competing measures in a horse race, bu...

Production and area of chickpea are reducing every year in India due tocompetition with horticulture and other cash crops in irrigated areas. There is a greatscope for expanding chickpea production with or without limited irrigation in rainfedrice fallow lands (RRFL) in the states of Chhattisgarh and Madhya Pradesh. Nineteenchickpea genotypes were tested using participatory varietal selection (...

The objective of this review paper was to summarise the latest findings in dairy cattle reproductive economics with an emphasis on high yielding, confined total mixed ration systems. The economic gain increases as the reproductive efficiency improves. These increments follow the law of diminishing returns, but are still positive even at high reproductive performance. Reproductive improvement re...

Generalized linear mixed models were developed using retrospective feedlot data collected on individually treated cattle (n = 31,131) to determine whether cattle performance and health outcomes in feedlot cattle were associated with timing of treatment for bovine respiratory disease (BRD) during the feeding phase. Cattle that died at any point during the feeding phase were removed from the anal...
