Can Yield of Late-planted Small Grains be Compensated by Water and Nitrogen Rates, 2016?

Ottman, Michael J, Sheedy, Michael D, Ward, Richard W 11 1900 (has links)
8 pp. / Wheat and barley are often planted later than optimum due to the timing of the previous crop or to reduce the risk of frost damage. It may be possible to partially compensate for lower yield potential of late plantings by increasing water and nitrogen rates beyond what would have an effect at more optimal plantings. The objective of this study is to evaluate the effects of nitrogen and water rates on late planted wheat and barley. A trial testing water and nitrogen rates for small grains planted late and at the optimal time was established at the Maricopa Ag Center. The experimental design was a split-split plot with main plots as input levels of water and nitrogen (low, medium, and high), subplots as varieties (Tiburon durum and Chico barley), sub-subplots as planting dates (15 December 2015 and 1 February 2016, and 3 replications. In this study, higher levels on inputs of water and nitrogen did not increase yield at later planting dates as we hypothesized. In fact, the highest yields were obtained at medium inputs of water and nitrogen regardless of planting date. The yields of the later planting date were not depressed as we expected due to unusually mild temperatures later in the spring which favored a later planting date this season.

Clipping small grains to increase subsequent grain yield

Ottman, Michael J, Sheedy, Michael D, Ward, Richard W 11 1900 (has links)
6 pp. / Wheat is commonly grown as a dual purpose crop especially in the Southern Great Plains where the forage is grazed then allowed to mature into a grain crop. In Arizona, clipping a crop planted in October may increase tillering and grain yield. A trial was conducted at the Maricopa Ag Center where various small grain varieties were planted on October 12, 2015, cut for forage on January 10, 2016, and allowed to go to grain and compared with the same varieties planted on December 3, 2016 and not cut for forage. No differences in grain yield due to planting date and clipping were detected. However, the October 12 planting with clipping had larger kernels, greater grain protein, and higher stem density. The income from the sale of the forage was $99/acre based a yield of 2639 lb/acre and a forage value of $75/ton. The added cost per acre to produce this forage included $29 for water (6.27 inches of water at $55/acre-ft) plus $34 for fertilizer (50 lb N/acre of urea at $433/ton). Therefore, even though grain yield was not increased by planting early and clipping, a net increase in revenue of $36/acre was realized from the sale of the forage.

A NEW PLEA FOR AN EARLY DATE OF ACTS

Armstrong, Karl L. 05 1900 (has links)
Although the date of Acts requires no introduction there has been consistent apathy in recent years with regards to this longstanding debate. While the ‘majority’ of scholars have been lulled into thinking it was written between 70 and 90 CE the vast majority of recent opinion is unanimously adamant that this middle range date is a convenient, political compromise. A large part of the problem relates to the recent and remarkable neglect of historical, textual, and source-critical matters. Compounding the problem further are the methodological flaws among the approaches to the middle and late date of Acts. A historiographical approach to the debate offers a stronger framework for evaluating the primary and secondary sources. Under this umbrella, and with the support of modern principles of textual criticism and linguistics, the historical context of Acts is determined to be concurrent with a date of 62-63 CE. This thesis also examines the much-neglected issue of Acts and its sources. As a consequence, it was found that there is no clear evidence that Luke used Paul's letters or the writings of Josephus—which (in concert with other evidence) effectively removes the plausibility of a late date of Acts. Additionally, the relationship between the date of Acts and the various interpretations on the end of Acts demonstrate that many of the modern and more recent theories are not only assumptive (especially with regards to genre), in some cases they utilize anachronistic literary methods that were originally applied to nineteenth-century novels. It is proposed below that the ancient interpretation (that Luke wrote no more because he knew no more) remains the most logical in light ofthe combined literary and historical evidence. This interpretation is further strengthened by a study of the variants at the end of Acts, the fall of Jerusalem (and its aftermath), the great fire of Rome and the subsequent persecution of Christians under Nero—all of which strongly indicate a pre-64 CE state of affairs. / Thesis / Doctor of Philosophy (PhD)

USING EXCEL MACROS FOR CHARTING

Kelly, Bryan 10 1900 (has links)
ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / This paper introduces a set of macros that automate the importing of antenna data into Excel and charting that data. These macros (as discussed here) import data from a ViaSat ACUs (Antenna Control Unit) and a TCS ACU (Telemetry & Communications Systems Inc). After the import is complete, the macros can build a set of charts, all formatted and labeled in a predetermined and standard manner. A task that may take half a day or more can be completed in minutes. The concept and layout of the macros lend them to quick adaptation to your data. In scenarios of “test and collect” followed by “import and chart”, the data can be imported and charted within the minute.

Best management practices of non-irrigated soybean (Glycine Max) production systems in the Mid-South

Reynolds, Daniel Zachary 13 December 2019 (has links)
Experiments were conducted to evaluate the most profitable and effective management practices for non-irrigated soybean production. Common production practices were compared side by side to evaluate yield response and economic returns. Combinations of row spacings and planting dates were evaluated to determine interactions between the two factors and also the effects on yield. Lastly, the effectiveness of various iron sources was examined in iron deficiency chlorosis (IDC) susceptible soybeans when applied foliar, inurrow at planting, and a split application. These data suggest that in non-irrigated soybeans, “low input management” practices do not maximize yields, but can be more profitable, depending on soybean market price and input costs, when compared to “full management”. Results also reveal that no interaction between row spacing and planting date occurred with respect to soybean yield. However, planting date did influence soybean yield with the earlier planting dates, mid-April, and mid-May providing the greatest yield. When examining row spacing, soybean grown on rows spaced 38.10 cm apart resulted in greater yield when compared to those grown on 96.52 cm rows. The iron product that consistently provided the greatest visual reduction of IDC symptoms was Sequestar 6% EDDHA chelate applied at 0.20 and 0.27 kg ai ha-1. This treatment was only effective when applied inurrow at planting. However, it was found that soybean yield was not influenced by any iron product or application timing, indicating that visual symptoms of IDC may be managed, but that the visual reduction in symptoms does not translate into yield.

Planting date and fertilizer effects on vegetable and cut flower production in high tunnels in Mississippi

Zhao, Yan 06 August 2011 (has links)
High tunnels have been used for many years worldwide. However, there has been limited research about use of high tunnel technology in the southeastern United States and its popularity has recently increased in Mississippi. A planting date study of 'Roma'' tomato, 'Legend' tomato, 'Ichiban' eggplant, 'Sweet Banana' pepper, ‘Benary’s Giant’ zinnia and ‘Potomac Red’ snapdragon was conducted in spring 2010 in three high tunnels in Starkville, Mississippi. Results showed for most cultivars (tomatoes, eggplant and pepper) a 12 Mar. 2010 planting date did not differ in marketable yield from planting on 2 Apr. 2010. In 2011, a fertilizer study on Encore lettuce mix and Ovation green mix was conducted both in high tunnel and in the field. Results indicated there was no effect of vermicompost tea or fertilizer treatments on yields of salad mixes.
