Influence of Cultivar and Planting Date on Strawberry Growth and Development in the Low Desert

Maurer, Michael A., Umeda, Kai 10 1900 (has links)
A field study was designed to determine the effects of cultivar and planting date on growth and yield of strawberries (Fragaria x annanasa D.) in the low desert. The study was conducted at the University of Arizona, Citrus Agricultural Center near Waddell, AZ. Treatments included two strawberry cultivars 'Camarosa' and 'Chandler' and three planting dates of 29 Aug., 7 Oct. and 24 Oct. 1997. There were no significant differences in fruit weight between cultivars . However, fruit number was significantly greater for 'Chandler' strawberries compared to 'Camarosa' and, therefore, fruit size was significantly smaller for 'Chandler' compared to 'Camarosa' berries. Fruit weight and number were significantly greater for both cultivars planted 29 Aug. with nearly 4 times greater production compared to the 7 Oct. and 24 Oct. plantings. Initial results of this study suggest summer planting (late Aug.) of strawberries in the low desert is necessary to produce economically viable yields.

Development of Best Management Practices for Fertigation of Young Citrus Trees

Thompson, Thomas L., White, Scott A., Maurer, Michael A. 10 1900 (has links)
Microsprinkler irrigation offers excellent flexibility for site-specific management of water and nitrogen inputs for citrus orchards in the southwestern United States. Escalating water costs, declining water availability, and increasing regulation of nitrogen (N) fertilizer use are causing growers to adopt practices to improve water and N use efficiency. 'Newhall' navels on 'Carrizo' rootstock were planted in Jan. 1997 and an experiment was initiated. This experiment was continued during 1999. The objective of the experiment was to develop appropriate management guidelines for N fertigation of 3-4 year old microsprinkler-irrigated navel orange trees. Treatments were factorial combinations of three N rates (0.15, 0.30, 0.45 lb N tree⁻¹ yr⁻¹) and three fertigation frequencies (3x/year, monthly, weekly). An untreated control was included. Trunk diameter was not responsive to N rate or fertigation frequency. Leaf N in all treatments, even controls, remained above the critical level (2.5%). However, at each N rate leaf N was highest with the weekly fertigation frequency. Nitrate analyses of soil samples indicate that nitrate leaching was highest with the highest N rate and 3x/year fertigation. Frequent fertigation is recommended because it results in higher leaf N and less nitrate leaching.

Players and layers : young men's construction of individual and group masculinities through consumption practices

Hein, Wendy January 2010 (has links)
Literature across a range of social science disciplines highlights the existence of multiple masculinities, performed and negotiated through everyday practices. However, many studies of male consumers have not explicitly addressed how practices construct gender. In consumer research, themes of masculinity have mainly emerged in studies of advertising images, subcultural consumption, brands, events and consumer tribes. Few studies have explored men’s consumption and the construction of masculinity through and across practices. Previous studies also appear to have examined gender, practices and identities at either individual or group levels. This study therefore sought to address the role of consumption in young men's construction of masculine identities, across a range of contexts, and at individual and group levels. Working within the Consumer Culture Theory tradition, these issues were explored through ethnographic research with young Scottish men aged 18-22, developed from contact with members of a football-themed University society. Data on collective practices were generated through non-participant observation followed by participant observation over a 13-month period. Practices included playing, watching and supporting football, visiting pubs and nightclubs, and playing poker. Accompanied shopping trips also formed part of the study. To gain further insights into individual identities long interviews with nine key informants were conducted. The analysis involved the iterative cycle of de-contextualising and re-contextualsing of data strips in the form of detailed reflexive fieldnotes, interview transcripts, photographs and film material. Masculinities emerged as contextualised, shifting and deeply rooted within practices of these young men. Their consumption produced normative ideals within groups. It also played a role in practices during which ‘masculine capital’ was sought. This capital was expressed through knowledge and experience in practices rather than objects and brands. Practices came to resemble games in which this capital was constantly contested. Through these games, groups also negotiated their place within the cultural context of gender relations. Consumption within practices constructed 'invisible’ gender identities through collectively shared meanings of masculinity. However, seemingly normal meanings of masculinity and consumption emerged as highly complex and layered as individuals constructed their multiple selves across practices. Rather than being fixed, consumption and masculinity was constantly (re)negotiated in changing contexts. This layered negotiation process of consumption meanings and masculinity was also reflected in informants’ discourse. This study suggests that various masculinities are 'played for’ through consumption across culturally situated practices. It shows how practices and consumption meanings shift during the negotiation of often contradictory and intertwined layers of gender identities. Methodologically, it offers insights into the challenges of gender differences between researcher and researched, and the role of new technologies such as mobile phones in ethnographic studies. Consumption and marketing messages may therefore allow young men to ‘do’, ‘talk’ and ‘be’ masculine across varying practices and contexts.

A Comparison of the Child-Rearing Attitudes of Disadvantaged Chicano and Black Mothers

Bond, Rebekah B. 08 1900 (has links)
Hypothesized in this study are the following: (1) that there are significant general differences between the childrearing attitudes of disadvantaged Chicano and Black mothers, (2) that their respective attitudes significantly vary on particular subtests of maternal attitude, and (3) that demographic variables, such as age, number of marriages, nativemigrant status, and level of education will affect significant differences in response on a number of specified attitudinal subtests.
