Abstract:
The main goal was to understand the trends of actual evapotranspiration (AET) and crop coefficient (<I>K<sub>c</sub></I>) in summer and winter seasons crops in Japan, maize, soybean, wheat and Italian rye-grass. Bowen ratio energy balance technique (BREB) was applied to measure the AET and heat flux between ground surface and atmosphere. Measurements were carried out using an automatic weather station (AWS) installed seasonally in the experimental farm of Tokyo University of Agriculture and Technology (TUAT). Penman-Monteith equation recommended by FAO was used to calculate reference crop evapotranspiration (ET<SUB>0</SUB>) and <I>K<sub>c</sub></I> was obtained from the ratio of AET to ET<SUB>0</SUB>. The results indicated that the average amount of daytime AET in the winter and summer seasons crops were approximately 2.5 and 3.5 mm, respectively monthly daytime. Daytime AET varied between 1.3 and 5.7 mm in winter season crops and between 1.4 and 6.5 mm in summer season crops. No significant differences between daily average values of AET for winter season as well as for summer season crops were found at 5% level of confidence (<I>t</I> = 0.9278, wheat and Italian rye-grass and <I>t</I> = 0.6781, soybean and maize). Average <I>K<sub>c</sub></I> values of summer season crops were found to be slightly higher than those of winter seasons crops. For planning the irrigation scheduling, it is quite necessary to understand the behaviors of AET and <I>K<sub>c</sub></I> during the growing season.

Abstract:
In tropical country such as Indonesia, the production for crops in dry land always depend on climatic condition especially rainfall for crop growth. Since the availability of the water is limited, therefore cultivation of crops is investigated. Indonesia has two seasons which are dry season and wet season. During dry season crops in dry land is of limited water supply, therefore crops meet its water requirement from soil water only. Heavy rainfall in the wet season, indicates water cannot fully conserved in the soil and some surface water lost as a runoff. This research was conducted with descriptive analysis method for analyzing the potential rainfall on the research center, and field observation method for calculating the potential of runoff water. Results showed that runoff on the area planted with single seasonal crop is greater than that planted with mixed seasonal crop. Also note that about 60 cubic meter of runoff that is stored in the storage pond can be used to irrigate of 70 square meters the area planted with sweet corn + sweet potato for two planting seasons. The harvesting runoff on dry land can increase cropping intensity from one to three times of planting per year. It can be said that the runoff harvesting is able to improve dry land farmers welfare.

Abstract:
Lupin is the major break crop used by farmers in Western Australia but neither lupin nor wheat uses much water from the B horizon of the widespread duplex soils. This study investigated the productivity and water use of a range of crops and pastures during 2 seasons on a shallow duplex soil, with a sandy layer 30-40 cm deep, at East Beverley, WA. The aims of the work were to evaluate the crops as alternative break crops to lupin on these soils, and to establish whether roots could proliferate in the clay layer, promoting both water extraction from the subsoil by that crop and improving yields of subsequent wheat crops. During the winter of the first season, a perched watertable developed for almost 3 months and some crops (especially lentil) grew poorly. Yields in the second season were generally good (lupin was close to the calculated potential yield and canola and Indian mustard were >2 t/ha), establishing that successful crops of oilseeds and grain legumes can be grown on this soil provided that there is adequate water without topsoil waterlogging. Yields of subsequent wheat crops were largest when following legume crops (40% in one season and 135% in the second compared with wheat following wheat or barley) but were also significantly greater following oilseeds (22% and 102%). Roots of cereals and pastures reached 80 cm in both seasons, whereas those of the oilseeds reached 60-80 cm depending on crop and season. Rooting depth of legumes varied from 70-80 cm for field pea to 30-50 cm for chickpea and faba bean, with lupin extending to 60 cm in both seasons. As with shoot mass, root mass differed between seasons, although on average, in mid September cereals and oilseeds had a smaller proportion (0·12 and 0·14) of total mass below ground than the legumes (0·24) and pasture species (0·18). Only a few millimetres of water was extracted from the subsoil by any crop in either season and there was no evidence that tap-rooted legumes or oilseeds were better able than other crops either to exploit subsoil water for their own use or to create pores that subsequent wheat crops might exploit.

Abstract:
Understanding the root growth and changes in soil moisture content during the growing season for dryland agriculture crops can improve crop production. It was hypothesized that early-season root growth might be influenced by previous crop and current crops, and soil moisture content and depletion pattern during the growing season and residual soil moisture may be affected by the crop type. A study was conducted on the early-season root growth of canola (Brassica napus L.), wheat (Triticum aestivum L.), and flax (Linum usitatissimum L.) in 2015; and changes in soil water content during the 2013, 2014, and 2015 growing seasons under canola, flax, wheat, barley (Hordeum vulgare L.), and pea (Pisum sativum L.). Early-season root growth of the canola and flax crops was better on wheat than canola stubble, while for wheat it was similar on the stubbles of both wheat and canola. Soil moisture depletion started relatively earlier under the barley and wheat and later under the flax compared to the canola and pea crops. Flax continued to deplete soil moisture for a longer period than the other crops. With some exceptions, all crops could deplete soil moisture to a similar level (down to about 15% or somewhat lower) by the end of their growing seasons. Generally, almost equal amounts of residual soil moisture remained after the different crops.

Abstract:
Although cassava can be planted throughout the year, its starch qualities may vary based on the date of planting. Seasonal variation on starch content, starch yield, starch granule size and amylose content of cassava cv. Rayong 9 grown under irrigated and rainfed conditions were studied for four planting dates in Thailand. A randomized complete block design with four replications was used in each planting. Planting dates consisted of hot-dry (20-Apr), early-rainy (30-Jun), late-rainy (5-Oct) and cool seasons (15-Dec). At final harvest, planting date accounted for the largest variations for starch yield (60.8%), starch granule size (38.2%), amylose content (50.5%) and ratio of amylose to amylopectin (53.7%), whereas starch content was affected more by water regime (52.1%). Supplemental irrigation did not significantly increase starch yield and other parameters for most planting dates, except for starch yield of the crop planted in the hot-dry season. This indicated that irrigation at the late-growth stages (during Sep to Mar) for the crop planted in the hot-dry season helped to increase starch yield; however, irrigation was unnecessary for other planting dates once cassava was established. The crops planted in the late-rainy and cool seasons had a greater starch content and starch yield than other planting dates for both irrigated and rainfed crops, whereas the crop planted in the hot-dry season had high starch yield for the irrigated crops only. In this study, the crops planted in the early-rainy season showed the worst performances for starch content and starch yield for both irrigated and rainfed crops. The data provided information on the responses of starch yield and its characteristics under irrigated and rainfed conditions at different planting dates, which can be useful for designing cultural practices with respect to water management and planting period in order to obtain optimum starch yield and qualities.

Abstract:
Strawberry (Fragaria ×ananassa) crops were transplanted in two seasons in central Florida with bare-root and containerized (plug) plants under three transplant establishment-period irrigation methods to evaluate crop fruiting responses and production economics associated with the various establishment systems. Irrigation was not required to establish plug transplants in the field. Early (first 2 months) fruit yield with nonirrigated plug plants was greater than early yield with sprinkler-irrigated bare-root plants (the current commercial system) in one of two seasons and equal in a second season. Total-season yields were similar in each season between the two establishment systems. Large or medium plug plants led to greatest early fruit yields in one season while large plug plants resulted in greatest early yield in a second season. Total yield was greatest with medium plants in one season and large plants in another season. The extra cost for the plug plant system was $1853/acre. In one out of two seasons there was increased net income amounting to $1142/acre due to greater early yield associated with the plug plant cultural system. Strawberry plug transplants showed promise for earlier and more profitable crops in addition to substantial savings in water used for plant establishment in the field. The ability to establish strawberry crops without irrigation will be important in areas where growers are required to reduce farm water consumption.

Abstract:
Intercropping is not a common practice in forage production in Sudan, in spite of its importance; farmers don’t know the potentiality of this type of cultivation and more experiments needed to adopt this type of cropping system and it is an example of biological interaction. A field experiment was conducted under irrigation for two consecutive seasons during 2013-2014 and 2015-2016 in the demonstration farm, college of Animal production, University of Bahri, Sudan to study the effect of intercropping of two leguminous forage crops (clitoria and phillipesara) cultivated with one non leguminous crop (Sorghum). Randomized complete block design (RCBD) was used. Yield of sole crops produced more forage, but the total yield (Over yielding) of the intercropped plants as revealed by land equivalent ratio was higher compared with the individual crops. Clitoria growth parameters (plant height, number of leaves and stem diameter) were not significantly affected by intercropping, but there was significant difference in plant population in the two seasons. Intercropping did not significantly affect growth parameters during the two seasons of Phillipesara except plant population and the first reading of plant height. Sorghum showed significant differences in plant population and some readings during the two seasons (the fourth reading of plant height in the first season, the first reading of number of leaves in first season, the fourth reading of stem diameter in the first season and the first reading of stem diameter in the second season).

Abstract:
In Mozambique, the sweet potato (Ipomoea batatas) is grown in the dry season in areas with a high water table, or as an irrigated crop. It is also grown in the rainy season when short-term droughts can occur. This paper reports the results of experiments designed to evaluate the effects of water availability and vine-harvesting practices on actual crop water use (cv. TIS 2534), during two contrasting seasons in the south of the country. Rain-fed crops extracted water to soil depths (variable sandy loam) of 0.75 m, with most (90%) taken from the top 0.25 m. Well-irrigated crops apparently obtained some (10%) water from below 0.75 m, but most (75%) came from the upper 0.25 m. Total water use from well-watered crops was about 800 mm during the rains, and 550 mm during the dry season. The corresponding values for rain-fed crops were 360 and 180 mm respectively. Peak rates of water use averaged 8 mm d−1 in the rainy season, and 5–6 mm d−1 in the dry season. Water use was not modified by the frequency of vine harvests. Actual rates of evapotranspiration fell below maximum values when the soil water deficit exceeded only 20 mm. By comparison, the maximum depth of extractable water in the root zone was 80–90 mm. The crop coefficients (Kc) for each stage of growth were consistent over both seasons and estimated to be: 0.55–0.7 (crop establishment), 1.1–1.2 (mid-season), and 0.8 (end-season).

Abstract:
Abstract. The Amazon rainforest evapotranspiration (ET) flux provides climate-regulating and moisture-provisioning ecosystem services through a moisture recycling system. The dense complex canopy and deep root system creates an optimum structure to provide large ET fluxes to the atmosphere, forming the source of precipitation. Extensive land use and land cover change (LULCC) from forest to agriculture in the arc of deforestation breaks this moisture recycling system. Crops such as soybean are planted in large homogeneous monocultures and the maximum rooting depth of these crops is far shallower than forest. This difference in rooting depth is key as forests can access deep soil moisture and show no signs of water stress during the dry season, while in contrast crops are highly seasonal with a growing season dependent on rainfall. As access to soil moisture is a limiting factor in vegetation growth, we hypothesised that if crops could access soil moisture, they would undergo less water stress and therefore would have higher evapotranspiration rates than crops which could not access soil moisture. We combined remote-sensing data with modelled groundwater table depth (WTD) to assess whether vegetation in areas with a shallow WTD had higher ET than vegetation in deep WTD areas. We randomly selected areas of forest, savanna, and crop with deep and shallow WTD and examined whether they differ on MODIS Evapotranspiration (ET), Land Surface Temperature (LST), and Enhanced Vegetation Index (EVI), from 2001 to 2012, annually and during transition periods between the wet and dry seasons. As expected, we found no differences in ET, LST, and EVI for forest vegetation between deep and shallow WTD, which because of their deep roots could access water and maintain evapotranspiration for moisture recycling during the entire year. We found significantly higher ET and lower LST in shallow WTD crop areas than in deep WTD during the dry season transition, suggesting that crops in deep WTD undergo higher water stress than crops in shallow WTD areas. The differences found between crop in deep and shallow WTD, however, are of low significance with regards to the moisture recycling system, as the difference resulting from conversion of forest to crop has an overwhelming influence (ET in forest is ≈2 mm d−1 higher than that in crops) and has the strongest impact on energy balance and ET. However, access to water during the transition between wet and dry seasons may positively influence growing season length in crop areas.

Abstract:
SUMMARYThe extent and severity of wheat take-all (caused by Gaeumannomyces graminis var. tritici (Ggt)) can vary considerably between growing seasons. The current study aimed to identify climatic factors associated with differing concentrations of Ggt DNA in soil and take-all disease at different stages of a sequence of wheat crops. Pre-sowing soil Ggt DNA concentrations and subsequent take-all disease in consecutive wheat crop sequences were compared across six seasons in 90 commercial cropping fields in Canterbury and Southland, New Zealand, between 2003 and 2009. Disease progress was assessed in additional fields in 2004/05 and 2005/06. While a general pattern in inoculum and disease fluctuations was evident, there were exceptions among wheat crop sequences that commenced in different years, especially for first wheat crops. In three consecutive growing seasons, there was very low inoculum increase in the first wheat crop, while increases in first wheat crops during the following three seasons was much greater. Low spring–summer rainfall was associated with low build-up of inoculum in first wheat crops. The inoculum derived from the first wheat then determined the amount of primary inoculum for the subsequent second wheat, thereby influencing the severity of take-all in that crop. Differing combinations of weather conditions during one wheat crop in a sequence and the conditions experienced by the next crop provided explanations of the severity of take-all at grain fill and the resulting post-harvest soil Ggt DNA concentrations in second wheat crops. Examples of contrasting combinations were: (a) a moderate take-all epidemic and high post-harvest inoculum that followed high rainfall during grain fill, despite low pre-sowing soil Ggt DNA concentrations; (b) severe take-all and moderate to high inoculum build-up following high pre-sowing soil Ggt DNA concentrations and non-limiting rainfall; and (c) low spring and early summer rainfall slowing epidemic development in second wheat crops, even where there were high pre-sowing soil Ggt DNA concentrations. The importance of the environmental conditions experienced during a particular growing season was also illustrated by differences between growing seasons in take-all progress in fields in the same take-all risk categories based on pre-sowing soil Ggt DNA concentrations.

Abstract:
Organic fertilizers promote improvements in soil properties and are important in providing balanced nutrients to plants. The officials parameters adopted by the Commission of Chemistry and Soil Physics in the States of Rio Grande do Sul Santa Catarina to calculate the amount of organic fertilizer are its mean composition and the efficiency index of nutrient release (EINR) to fulfill the demand of each system crops. This indicator is related mainly to the type of organic residual, but the other factors affecting the mineralization are not adequately addressed, such as climatic conditions and soil texture, among others. The expectation of this work is that these factors are especially relevant in regions with large variation of soil types and climatic conditions, such as the South of Brazil region. So, the factors cropping season and soil texture were studied under the application of two different organic sources (pig slurry and chicken litter) in the field and in laboratory experiments. The texture effect was analyzed in an incubation of three soils containing 238, 470 and 605 mg clay kg soil-1, which was evaluated during 112 days of evolution of mineral nitrogen (N-NH4+ + N-NO3-), the net mineralization and % mineralization of total N and organic added. The influence of growing season was tested under field conditions in two crop series starting with the potato (summer and winter), which evaluated the productivity and nutrient cycling in three crops per system. The results of incubation showed that soil type affects the N dynamics in the soil after the addition of organic fertilizers. Most clayey soils make slowly immobilization and nitrification of ammonium, independently of addition of the broiler litter or pig slurry, which reduces the N pollution potential. The net N mineralization was greater in sandy soil due to lower physical-chemical protection of colloids. Also were greater with the chickens litter due to the amount of total N added have been much higher compared to pig slurry. The results of N available to plants (%NAP) and net mineralization of nitrogen in the soil (%Nminnet) with the addition of organic fertilizers indicate that EINR is overestimated in relation to N effectively added to the soils, and can result in depletion of soil organic matter in the long term growing. Also concludes that, to sandy soils or when manure are rich in available N, that must be done a N fractionated application between plantation and cover fertilization. In field experiments, there would significant differences in the efficiency of release of N in cropping systems of "summer" and "winter". The immediate effect was equal in the summer period to all fertilization sources, but in the winter the mineral source was 10-20% more efficient, showing the effect of temperature and soil moisture in the availability of N in soils under organic fertilization. The residual effect of chickens litter in the second crops was lower than expected in comparison to the pig slurry and mineral fertilizer, since the efficiency index of N liberation would be 20% for chickens litter and zero for the slurry. However only in the third crop that litter exceeded the slurry in dry matter production of summer crop (maize) and winter (black oat). Finally, due very different climatic conditions in South of Brazil, the results indicate that it necessary more and integrated studies about the impact of crop date and soil type to refine the parameters of the recommendation of organic fertilizer, making it thus more sustainable.
Os adubos orgânicos promovem melhorias nas propriedades do solo e são importantes no fornecimento equilibrado de nutrientes às plantas. Os parâmetros oficiais adotados pela Comissão de Química e Física do Solo dos Estados do Rio Grande do Sul Santa Catarina para calcular a quantidade de adubo orgânico, são a sua composição média e o índice de eficiência de liberação dos nutrientes (IELN) frente à demanda de cada sistema de cultivos. Este último indicador está associado essencialmente ao tipo de resíduo, porém os demais fatores que afetam a mineralização não são devidamente considerados, como as condições climáticas e a textura do solo, entre outros. A expectativa do presente trabalho é de que esses fatores sejam especialmente relevantes em regiões de grande variação edafoclimática, como o Sul do Brasil. Assim, os fatores época de plantio e textura do solo foram estudados sob a aplicação de duas fontes orgânicas distintas (dejeto líquido suíno e cama de aves de corte), a campo e em laboratório. O efeito da textura foi discutido numa incubação de três solos contendo 238, 470 e 605 mg argila kg de solo-1, onde se determinou a evolução do N mineral (N-NH4+ + N-NO3-) durante 112 dias e se calculou a mineralização líquida e a % de mineralização do N total e orgânico adicionados. Já o efeito da época de cultivo foi testado a campo em duas sucessões iniciadas com cultura da batata (denominados de cultivos de verão e de inverno), onde se avaliou a produtividade e a ciclagem de nutrientes de três culturas por sistema. Os resultados da incubação mostraram que o tipo de solo afeta a dinâmica do N no solo após a adição de adubos orgânicos. Solos mais argilosos retardam a imobilização e a nitrificação do amônio, independente de se utilizar cama de aves de corte ou dejeto líquido de suínos, contribuindo para diminuir o potencial poluente do N. A mineralização líquida do N foi maior no solo arenoso devido à menor proteção físico-química da sua fração coloidal. Também foi maior com o uso da cama de aves de corte, em todos os solos, em função quantidade de N total adicionado ter sido bem maior em relação ao dejeto de suínos. Os resultados de N disponível às plantas (%NDP) e de mineralização líquida do N no solo (%NminL), com a adição dos adubos orgânicos, sinalizam que o IELN está superestimado em relação ao N que é efetivamente adicionado aos solos, podendo levar à depleção da matéria orgânica do solo a longo prazo. Também se infere que, para solos mais arenosos ou quando se dispõe de dejetos ricos em N disponível, faça-se a aplicação fracionada do N entre o plantio e em cobertura. Nos experimentos de campo, por sua vez, houve diferenças significativas na eficiência de liberação do N nos sistemas de cultivo de verão e de inverno . O efeito imediato foi igual no verão para as fontes cama de aves, dejeto suíno e adubo mineral, mas no cultivo de inverno a fonte mineral foi entre 10 a 20% mais eficiente, demonstrando o efeito da temperatura e da umidade na disponibilização de N nos solos sob adubação orgânica. O efeito residual da cama de aves no segundo cultivo foi inferior ao esperado na comparação com o dejeto suíno e adubo mineral, visto que o índice de eficiência de N seria de 20% para a cama e zero para o dejeto. Porém, foi só no terceiro cultivo que a cama superou o dejeto na produção de matéria seca no cultivo de verão (milho) e de inverno (aveia preta). Por fim, dada a grande diversidade edafoclimática no Sul do Brasil, os resultados apontam que se devem fazer mais estudos e de forma integrada sobre o impacto da época de plantio e tipo de solo para aperfeiçoar os parâmetros de recomendação da adubação orgânica, tornando-a assim mais sustentável.

Abstract:
High tunnels are used to modify the crop environment by trapping solar energy, providing protection from unfavorable weather events, and extending the growing season in temperate regions. This project assessed yield and quality in three independent cultivar trials of warm-season crops tomato (Solanum lycopersicum L.), bell pepper (Capsicum annuum L.) and cucumber (Cucumis sativus L.) grown under high tunnel production compared with an outdoor field in eastern and western North Dakota. Tomato yields in the high tunnel were increased by 1.4 times over the field trial yields. Yields from the pepper cultivar trials both inside the high tunnel and outside field were comparable to one another at 1.24 kg plant-1 and 1.06 kg plant-1, respectively. Cucumber yields in the high tunnel were increased by 1.7 times over the field trial yields. Results indicate that in North Dakota, high tunnels extended the growing season, and increased production relative to field conditions.

Abstract:
In the latter part of the 1997 season (August) many fields across Arizona, from Marana to the Mohave Valley, were experiencing premature senescence. In an effort to evaluate the conditions leading to the symptoms and to possibly determine the causes, an extensive series of field examinations were conducted in a number of representative fields in central Arizona. Soil samples were taken from selected fields that ranged in expression of the symptoms from very light to severe. Complete analyses of the soil samples were conducted. Plant tissue samples were also collected and analyzed for plant nutrient levels. No absolute causal agent was identified. However, a factor believed to be of significance was that of low soil K levels, where many of the fields expressing the most severe symptoms also had low soil K levels. It is also important to consider the fact that plants exhibiting K deficiency are very similar in appearance to plants affected by Verticillium wilt, which also appeared to be a primary or contributing factor in many cases.

Abstract:
A field experiment was conducted during the 2002 growing season to evaluate a central Arizona grower’s method of addressing cotton fiber micronaire based on the management and timing of his agronomic inputs.

Abstract:
A field experiment was conducted during the 2002 and 2003 growing seasons to evaluate a central Arizona grower’s method of addressing high cotton fiber micronaire based on the management and timing of agronomic inputs. In-season management and irrigation termination combined with defoliation methods has led to consistent production of premium fiber micronaire in recent years. Steps to accomplish crop defoliation and the subsequent mixing of seed cotton from the top (younger) and lower (older) bolls achieved at harvest are intended to keep the micronaire at premium levels and further prevent discounts on the crop. A companion study was conducted in 2002 at the University of Arizona Maricopa Agricultural Center (MAC-1,175 ft. elevation) in an effort to duplicate the grower’s late season crop management operations. This study consisted of two treatments, a control (conventional) which received an application of 10 oz. Ginstar combined with 1/2 pt. surfactant in 20 gal./acre carrier and a treatment which received the conventional treatment in addition to a predefoliation of Accelerate and a post-defoliation of Gramoxone, consistent with the grower’s methods. At the grower’s location, data was collected during the 2002 and 2003 seasons. In 2002 and 2003, plant growth and development measurements taken in-season revealed that height to node ratio (HNR) and fruit retention (FR) levels tracked well and were similar for both sites and years (grower’s fields and MAC study). Lint yield estimates indicated no difference between conventional defoliation and the treatment receiving additional compounds at MAC in 2002. Average yield estimates were high for the cooperator-grower fields in both the 2002 and 2003 seasons. Results of the analysis performed on final micronaire data indicated no significant difference in micronaire values between the two methods of defoliation and late season management at MAC. In addition, fiber micronaire values exceeded the premium level (>5.0) for both treatments at MAC. In contrast, the data of 2002 and 2003 obtained from the cooperator-grower gin records revealed consistent results for average fiber micronaire for all of the fields monitored in this project which were at premium levels (<5.0).

Abstract:
A heat-unit-based planting window was introduced in 1991 as a means of reducing early season problems with pink bollworm (PBW). Growers were encouraged to plant full season varieties when the annual heat unit (HU) accumulation ranged between 600 and 900 -- a window designed to ensure 75% suicidal emergence of PBW yet maintain acceptable yield levels. New research findings and a reexamination of past PBW emergence studies now support making an adjustment to the planting window. For 199Z the recommended planting window is 450 - 700 HUs after January 1.

Abstract:
Demand for potassium (K) increases with increasing soybean yield. Little research has been conducted on soybean response to K on coastal plain and piedmont soils of Virginia, especially in double-crop systems. Nineteen full-season and 14 double-crop soybean experiments were conducted in 2013 and 2014 in Virginia and northeastern North Carolina to determine full-season and double-crop soybean (with wheat straw remaining or removed) response to soil test K and K fertilizer application rates. Field moist, air dried, and oven dry soil test K extraction techniques were also compared to predict responsiveness of sites to K applications. Potassium fertilizer increased yield in five of 19 full-season experiments and one of 14 double-crop experiments. Full-season soybean yield plateaued at 88% relative yield and soil test K value of 38.8 mg K kg-1. Full-season plant K critical concentrations were 18.2 g K kg-1 for V5 and 24.6 g K kg-1 for R2. Although critical concentrations could not be determined for double-crop soybean, V5 and R2 concentrations ranged from 17.6 to 35.6 g K kg-1 or 13.2 to 28.1 K kg-1, respectively, most of which were within or above accepted sufficiency levels. Eight of 13 sites resulted in greater soil K concentrations when alternative soil drying methods were compared to air-dry methods. However, differences were not consistent and no single method was superior for these soils. More data is needed for double-crop soybean systems due to lack of response and lack of low soil test K sites in these experiments.

Abstract:
Faba bean (Vicia faba Roth) is grown worldwide as a protein source for food, used for animal feed, and is a common cover crop in Europe, but is underutilized in Midwest farming systems. Faba bean, field pea (Pisum sativum L.), and forage pea were evaluated for biomass and chemical composition when sown after wheat. Faba bean, forage pea, balansa clover (Trifolium michelanium Savi), red clover (T. pratense L.), and rye (Secale cereale L.) were evaluated similarly when intersown into maize. Cover crops after wheat had no significant biomass differences, averaging 1210 kg ha-1, enough to support 1.5 animal unit month (AUM) ha-1 for a 450 kg cow with calf. Rye yielded the greatest (374 kg ha-1) of the intercrops with faba bean averaging similarly and other intercrops averaging significantly less. Intercrops did not affect maize yield. Faba bean has similar potential as other commonly used cover crops in the Midwest.

Abstract:
A monitoring program is essential in assuring goal attainment and reducing the risk of overtraining or undertraining, establishing long-term athlete development, and ensuring success. This monitoring program needs to be integrated into the training process, developed, and executed by both the sport science and coaching staff. This staff forms the SPEG (sports performance enhancement group), which is athlete centered and coach driven. The purpose of this dissertation was to create an evidence based, or white box approach, to collegiate distance running by identifying key characteristics, utilizing appropriate monitoring tools, and examining the annual plan. Collegiate distance runners took part in a monitoring program through East Tennessee State University, which included vertical jumps, V̇O2max, running economy, anthropometrics, isometric mid-thigh pull, performance results and ultrasound measurements. There were strong correlations between performance results and monitoring data, and there were significant changes that occurred throughout the monitoring program. The results indicate the importance of V̇O2max in collegiate runners and that monitoring variables, including performance, sum of skinfolds, ultrasound and vertical jumps significantly change throughout the competitive season. The results also identify characteristics of a high-level runner and indicate the impact that a strength program can have on monitoring variables and performance. Results further suggest that strength can be a critical component of a training program, can be tracked through systematic monitoring, and is associated with an increase in performance.

Abstract:
AbstractClimate change and climate variability in Malawi have negatively affected the production of maize, a staple food crop. This has adversely affected food security. On the other hand, there have been increases in growing area, production, yield, consumption, and commercialization of both cassava and sweet potato. Factors behind these increases include the adaptive capacity of these crops in relation to climate change and variability, structural adjustment programs, population growth and urbanization, new farming technologies, and economic development. Cassava and sweet potato are seen to have the potential to contribute to food security and alleviate poverty among rural communities.This study used a simple generic growth index model called GROWEST to model observed yields of maize, cassava, and sweet potato across Malawi between 2001 and 2012. The method can be viewed as a hybrid approach between complex process-based crop models and typical statistical models. For each food crop, the GROWEST model was able to provide a robust correlation between observed yields and spatially interpolated monthly climate. The model parameters, which included optimum growing temperatures and growing seasons, were well determined and agreed with known values. This indicated that these models could be used with reasonable confidence to project the impacts of climate change on crop yield. These projections could help assess the future of food security in Malawi under the changing climate and assist in planning for this future.

Abstract:
Eurasian Beaver (Castor fiber L.) was reintroduced in Lithuania on 1947. Population growth was quite rapid ant there were about 6000 beavers on 1970. Nowadays beavers population in Lithuania is about 40 000. Beavers have a possibility to affect the environment where they live by building dams, lodges, making burrows systems, changing water level. Because of being such an active environmental former beaver has a huge indirect impact for forest and agricultural fields – higher water level usually causes damage for forest trees or crops. There are different studies about this beaver’s ability to change environment and to build dams, lodges. Explanations why it is needed for this species now is clear, but still there are question how can these animal plan, organize and improve their ability to build. The aim of this research is to find out if dams rebuilt activity intensity differs during different year seasons and is it affected by the beaver’s family size in current place. According to our findings, the beginning of dam rebuilt and total dam rebuild depends on year season – on fall season it takes 4 times less time. In addition to this, family size has an effect – bigger families rebuilt dams faster. Usually beavers do this job from midnight to 2 a.m. on fall season.

Abstract:
The application of greenhouse technology for cultivation of high value crops is rapidly expanding worldwide. But the requirement of electricity imposes a restriction on the emanation of this technology to areas which are remote. In a developing country like India, where a significant number of villages are yet to be connected to any national or regional grid, this restriction assumes considerable significance. The present paper has been divided into two parts: The first part dealing with the performance analysis of a floriculture greenhouse located in the plains of Indian subcontinent equipped with fan induced ventilation system and wet pad along with shading screens. The second part deals with the performance analysis of the greenhouse integrated power system comprising of solar photovoltaic array, electrolyser and fuel cell stacks. The hourly photovoltaic generation, load consumption, cumulative daylong hydrogen gas generation and consumption have been computed for various seasons of a climatic cycle and presented in this paper.

Abstract:
Combine harvesters play a crucial role in grain harvest. Due to seasonal character of work of these machines is necessary to achieve high standard in durability and reliability during working period. There is lots of requirements that have to be done according to the crop type, field conditions and as well as high performance and lower costs. Combine harvesters are the main harvesting technology of cereals in the world and main piece of work should be done in short time. The aim of this paper is an economic analysis of combine harvester’s fleet in different working conditions. The evaluation is based on exact costs analysis of combine harvesters New Holland brand sort by different ages and different concepts of threshing. Used data were collected during all working seasons of combines. There is a data set from 10 seasons. There is two groups in evaluation - 9 machines NH CR 9080 and another 9 machines NH CX 8080. Working parameters evaluated are fuel consumption and operational costs. Thanks to on board computer we have data about performance of each machine per day and per whole season. Costs are calculated as fixed and variable and then summarized for every machine. The result shows that effect of costs analysis depends on annual performance of the machine. There is positive effect on depressing fixed cost due to higher performance in season. A special result of this study is evidence of intervenes reason during all seasons and setting up the coefficient of repairs for the group of combines.

Abstract:
Statistics of storm peaks over threshold depend typically on a number of covariates including location, season and storm direction. Here, a non-homogeneous Poisson model is adopted to characterise storm peak events with respect to season for two Gulf of Mexico locations. The behaviour of storm peak significant wave height over threshold is characterised using a generalised Pareto model, the parameters of which vary smoothly with season using a Fourier form. The rate of occurrence of storm peaks is also modelled using a Poisson model with rate varying with season. A seasonally-varying extreme value threshold is estimated independently. The degree of smoothness of extreme value shape and scale, and the Poisson rate, with season, is regulated by roughness-penalised maximum likelihood; the optimal value of roughness selected by cross-validation. Despite the fact that only the peak significant wave height event for each storm is used for modelling, the influence of the whole period of a storm on design extremes for any seasonal interval is modelled using the concept of storm dissipation, providing a consistent means to estimate design criteria for arbitrary seasonal intervals. Characteristics of the 100-year storm peak significant wave height, estimated using the seasonal model, are examined and compared to those estimated ignoring seasonality.

The work demonstrates the results of the 6-years complex ship-borne monitoring of coastal zone in the north-eastern part of the Black Sea, carried out by the Southern Branch of P.P.Shirshov Institute of Oceanology, RAS, on a marine cross-section at the Blue Bay (Gelendzhik) beam 1-2 times per month. Climatic changes and eutrophication exert a significant impact on the sea water at the coastal area. In case of the Black Sea these factors pile up with a permanent hydrogen sulphide contamination of the sea water below 80-200 meters depth (depending on the season and distance from the shore). Strong pycno-halocline at the depths from 70 to 160 meters, formed due to the inflow of high salinity water from the Marmara Sea, inhibits the mixing between the water layers and, as a result, also limits the oxygen transport into the deeper layers. The winter cooling reduces the pycno-halocline and enriches the top active layer, down to the cold intermediate layer (CIL), with oxygen and nutrients, which subsequently lead to a vernal phytoplankton bloom. Formation of the thermocline and upper quasi-homogeneous layer (UQL), caused by the water warming in spring, at large extent determines a thickness of phytoplankton-rich layer during the spring and summer seasons. The work demonstrates seasonal and interannual dynamics of the UQL, thermocline, CIL and hydrogen sulphide boundary position in the coastal zone of the north-eastern part of the Black Sea.

Abstract:
The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States. It spends its life in aquatic habitats and is well adapted for swimming. Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth. Laws, regulations, and ordinances regarding the take of muskrats varies by state and province where they are found and regulations on seasons, bag limits, and type of traps or devices that can be used to take them must be carefully followed.

Abstract:
Federal crop insurance provides a financial safety net for farmers against insured perils such as drought, heat, and freeze. In 2016 over $100 billion dollars of crops were insured through the Federal crop insurance program administered by the U.S. Department of Agriculture Risk Management Agency. In this white paper, we analyze publicly-available Federal crop insurance data to understand how weather and climate-related perils, or causes of loss (COL), change over time and spatial areas. We find that over 75% of all weather/climate-related indemnities (i.e., crop losses) from 2001 to 2016 are due to three COL: drought, excess moisture, and hail. However, the extent to which these top COL and others impact indemnities is highly dependent on the time period, temporal scale, and spatial scale of analysis. Moreover, we identify what COL are region- or season-specific, and visualize COL trends over time. Finally, we offer a road map of research applications to quantify such trends in indemnities, as well as outreach and extension efforts that include an online data portal.
