Agronomic characteristics of intercropped legume and cereal crops.

Menezes, Eduardo Assis. January 1988 (has links)
Research was conducted in the summers of 1985 and 1986 at the University of Arizona Marana Agricultural Center, with the objectives of (1) determining the best intercropping species combination under near optimum irrigation, using three cereals (sorghum (Sorghum bicolor), maize (Zea mays), and pearl millet (Pennisetum americanum) and three legumes (field bean (Phaseolus vulgaris), cowpea (Vigna unguiculata), and soybean (Glycine max) in all combinations, and (2) identifying species genotypes best adapted to intercropping. Results from 1985 determined sorghum x soybean as the most appropriate intercropping combination for the environment of the Marana Agricultural Center. In the 1986 cropping season, three sorghum genotypes (Pioneer 8493, Funks G-522DR, and California IO80H40) were combined with three soybean genotypes (Asgrow A6242, Asgrow A6520, and Rillito), to identify the best genotype combination for intercropping. Both 1985 and 1986 experiments were carried out in a randomized complete block design with four replications. Pearl millet was the cereal with the greatest decrease in yield when intercropped, indicating that this cereal was not a good competitor with legumes. Sorghum was the best cereal competitor with the legumes and soybean was the best legume competitor with the cereals. Among the three sorghum genotypes studied in 1986, only Pioneer 8493 showed higher yield in monocrop whereas the other two genotypes yielded higher in intercropping, indicating some benefit from this system. On the average, all three sorghum genotypes showed intercropping to be advantageous, with high Land Equivalent Ratio values. Soybean genotypes showed drastic decreases in yield when intercropped. Asgrow A6520 soybean had the highest yield in intercropping. Sorghum #3 (California IO80H40) and soybean #3 (Rillito) were chosen as the most appropriate genotypes for intercropping, for the environmental conditions of the study.

When the Bond Breaks: Variables that Influence Grief Following Companion Animal Loss

Cowling, Dawn 20 November 2013 (has links)
An online survey investigated variables that are related to grief, guilt and loneliness following companion animal loss. Variables of interest were: relationship, species, time since death, type of death, attachment, social support, and demographic variables. Female and male participants over eighteen (n = 85) who had lost a companion animal within the last six months completed the survey. Individuals who classified their pets as good companions reported significantly less grief relative to those who considered their pets to be their children (p < 0.001) and best friends (p = 0.001). Those who labeled their animal as “my child” had significantly higher attachment scores when compared to those who labeled their pet as “a good companion” (p = 0.012). Older age was predictive of significantly lower grief, situational guilt, and loneliness. High grief participants considered their pets to be their children and reported the highest state guilt, loneliness and attachment scores.

An evaluation of corn yield, intercrop growth and soil nitrogen levels in silage and grain corn intercrop systems /

Hope-Simpson, Margaret E. (Margaret Ellen) January 1992 (has links)
The objectives of this study were to evaluate the effects of earlier corn (Zea mays L.) harvest, on corn yield, intercrop growth, and soil N levels, and to evaluate the effects of red clover (Trifolium pratense L.) compared to ryegrass (Lolium multiflorum Lam.) as intercrops on corn yield and soil N levels. / After two years, earlier corn harvest did not result in greater intercrop growth or higher soil N levels compared with later corn harvest and there was no significant soil N contribution by legume intercrops in either harvest period. Thus, no soil N benefit was found from using intercrops in earlier harvest for silage compared to later harvest for grain corn, nor from using red clover compared to ryegrass as an intercrop. / In the early harvested silage system, a quadratic corn yield response to added N suggested that near-maximum corn dry matter yields were obtained at the rate of 140 kg N ha$ sp{-1}$. Maximum total dry matter yields were not obtained in the late harvest grain system in any site-year. Legume and non-legume intercrop species had similar effects on corn yield.
