Abstract (sommario):

Weeds pose a major challenge to crop productivity, significantly impacting maize (Zea mays L.), which is Nepal’s second-most important staple crop. Although attainable yield 5.8 t ha⁻¹, the national average is only 3.15 t ha⁻¹, largely due to issues like weed competition that can lead to yield losses of up to 48%. This study, carried out during the winter season at the National Maize Research Program in Rampur, Chitwan, evaluated nine different weed management treatments, weedy check, weed free, green polythene mulching, clear polythene mulching, cowpea co-culture, black polythene mulching, atrazine + one hand weeding @ 30 DAS, silver black polythene mulch and Lantana camara as mulch in a randomized complete block design with four replications. The results showed that mulching methods, particularly silver-black polythene mulch, significantly enhanced growth parameters, grain yield (4,537.5 kg ha⁻¹) and stover yield (6,500 kg ha⁻¹). Furthermore, mulching facilitated earlier tasseling (73.19 DAS) and silking (85.31 DAS), while also improving soil moisture retention, and weed suppression. Both clear and black polythene mulches had beneficial effects on growth and yield. Similarly, grain yield in Lantana camara as mulch and Atrazine @ 0.75 kg ha-1 + one hand weeding also remain same with clear polythene mulch.

Abstract (sommario):

Una alternativa para optimizar el uso del agua de lluvia en regiones semiáridas para la producción de cultivos, es el uso de coberturas vegetales (mulch). El objetivo del estudio fue evaluar la influencia de dos fuentes de mulch bajo dos niveles de uso en el rendimiento de frijol (Phaseolus vulgaris) var. Red Kidney y en la reducción de la evaporación del agua del suelo en Canaán, Ayacucho. El experimento consistió en un ensayo factorial 2x2 (fuentes de mulch: residuos de trigo y de grass; niveles de uso: 5 y 10 t ha-1) más un testigo, en parcelas de 8,75 m2, bajo el Diseño de bloques completos al azar. Se utilizaron evaporímetros de balanza para determinar la reducción relativa de la evaporación del agua del suelo (Reas), en suelos con mulch respecto al suelo sin mulch. Los resultados mostraron que la evaporación del agua en suelos con mulch es significativamente menor que en suelos sin mulch; la Reas por aplicación de mulch es superior en los suelos con mulch a base de residuos de grass. La aplicación de 7.5 t ha-1 permite una Reas de 69% con residuos de trigo y 77% con residuos de grass. Los rendimientos de frijol también están influenciados por la fuente y niveles de mulch, siendo superior hasta un 98% al utilizar 10 t ha-1 de mulch de residuos de grass y hasta un 49% con residuos de trigo.

Abstract (sommario):

Sustainable agriculture requires increasing human productivity to meet current needs while preserving the ability of future generations to produce food. One of the keys to achieving this is proper soil management, which includes tillage and appropriate soil improvement measures. One of the significant impacts of tillage on the sustainability of the soil environment is manifested through its impact on the soil itself. This includes soil degradation, pollution of water resources, and the release of greenhouse gases associated with soil processes. The need for sustainable solutions is particularly important in areas facing various constraints. This reality highlights the urgent need to implement practices that balance productivity with natural resource conservation. The choice of an appropriate agronomic practice, such as mulch-till technology, complemented by no-till and strip-till, can have a significant positive impact on both agricultural production and the environment. This study focuses on the impact of mulch-till technology as a concrete example of an agri-environmental practice that aims at soil conservation while contributing to environmental protection. The paper includes a review of existing literature to analyse the concept and application of mulch-till technology. Furthermore, the effects of the introduction of this technology in agricultural activities are considered, and the potential future benefits for sustainable development and environmental protection are assessed.

Abstract (sommario):

American mayapple (Podophyllum peltatum L.) is a rhizomatous herbaceous perennial found in wooded areas of eastern North America and is a source of the pharmaceutical compound podophyllotoxin. To explore the possible domestication of this species, this research examined strategies for establishing mayapple in field plantings using organic mulches. Mayapple rhizome segments were harvested from the wild and transplanted to raised beds in northern Mississippi in Fall 2001. Two types of mulch (pine bark or wheat straw), two depths of mulch (7.5 or 15 cm), and two planting depths (0 or 5 cm) of rhizome segments were examined in a factorial arrangement and randomized complete block design. Data were recorded during spring of 2002 and 2003. Shoot number was not affected by mulch depth, but there was a significant interaction between mulch type and rhizome planting depth. Rhizome segments planted 0 cm deep and covered with straw mulch produced about 30% fewer shoots compared to any of the other treatment combinations. Number of emerging shoots was also affected by year, with a 33% increase in shoots from 2002 to 2003. Total leaf area and total leaf dry weight were not affected by mulch depth, but there was a significant three-way interaction between mulch type, rhizome planting depth, and year. During 2002, treatment combinations were not different, but during 2003 rhizome segments planted 0 cm deep and covered with straw mulch produced less leaf area and leaf dry weight than any of the other treatment combinations. The ratio of sexual shoots to total shoots was affected by year, with a higher ratio of sexual shoots occurring in 2002 than 2003. Grasses established in bark mulch to a greater extent than in straw mulch in 2002, but weed control was excellent for all treatments in 2003. These results indicate that rhizome segments planted 0 cm deep and covered with straw mulch consistently produced fewer shoots with less leaf area and dry mass compared to any other treatment combination. We preferred bark mulch, but we can recommend either bark or straw mulch for the purpose of establishing field plantings of american mayapple in full sun as long as rhizome planting depth is 5 cm. There was no difference between the two mulching depths used in this study; therefore, a mulch depth of 7.5 cm can be recommended because of its lower cost.

Abstract (sommario):

This study was conducted to provide students with an understanding of the effect of using sawdust and coconut husk mulch on the production of shallots (Allium ascalonicum L.), and to determine whether this learning model can be applied in the learning process of horticulture courses at IKIP Saraswati. This type of research is experimental, using a simple experimental posttest only control group design. The population of this study were shallot bulbs taken from agricultural shops with relatively the same dryness and weight. The total population is 500 shallot bulbs. From a population of 500 bulbs, 180 bulbs were taken as samples. Sampling was done randomly. This experiment was grouped into 2 groups with three replications. The first group was given coconut coir mulch and the second group was given sawdust mulch. The data obtained in the form of production (wet weight) of shallot bulbs were tested for normality. If the normality requirements have been met, then a parametric analysis with a t-test is carried out. Student learning outcomes using experimental-based learning methods were evaluated using formative assessment. The results of this study indicate that there is a significant difference between the production (wet weight of bulbs) of shallots treated with coconut coir mulch compared to sawdust mulch. Where the treatment with coconut coir mulch gives an average wet weight of shallot bulbs which is superior to sawdust. The use of this experimental-based approach improves students' ability to communicate, and interpret the results obtained from direct observation. It also motivates students to improve cognitive, social, psychomotor and problem solving skills, redefine their theoretical understanding of different concepts, apply deductive and inductive reasoning skills, and encourage collaboration between students. So this experiment needs to be applied in the learning process of horticulture courses at IKIP Saraswati.

“” IJAAR welcome all of you to submit your research paper for publication in the field of Agriculture, Agronomy, Horticulture etc. Please submit your manuscripts via Online submission panel .“” The effort to scale up soybean production is by agro forestry system. However, these conditions give a response to the plants because the light is reduced by the canopy of trees so that affects the plant microclimate and plant physiology. This study aimed to analyze the effect of using reflective mulch to physiology character and soybean production in shaded and not shaded conditions. The efforts to increase the light that reach the plants is by using reflector. The research conducted in Bogor, West Java Indonesia using nested design-two factors model, the first factor had two levels, respectively shade 50% (N50%) and without shade (N0%). The second factor had reflector mulches three levels, respectively black silver mulch (MP-PH), metalic mulch (MP-MA) and without mulch (M0). The results showed that the using of reflective mulch in 50% shade condition were able to give a positive response to physiology and crop production. The using of mulch increased the rate of plants photosynthesis significantly in 50% shade condition 14.52μmol μmol CO2.m-².s-1 for the black and silver mulch and 18.17μmol CO2.m-².s-1 for metalic mulch, whereas only 12.61μmol CO2.m-².s-1 for the control (M0). The increase of photosynthesis rate was positively correlated in the increase of crop yields 4.79 and 4.79 tons/ha respectively for metallic mulch and silver black mulch, whereas 2.93 tons/ha for without mulch in 50% shade condition. In 0% shade condition, the potential yield were 5.17, 4.11, 3.43 tons/ha respectively for silver black mulch, metallic mulch, and without mulch.

Abstract (sommario):

The plastic mulch films, which are mostly made from LDPE, are used in order to increase the yields and to prevent the weed growth by covering the top of the soil by leaves or straw in nature. After a period, the mulch films turn into unmanageable quantities of soiled plastic films, which cause an environmental problem. Using degradable mulch films for agricultural purposes can be a solution for the environmental problems caused by the plastic mulch films. In this study, to introduce biodegradability to mulch films, a natural biopolymer starch was used. Before blending, starch was transformed into thermoplastic starch in order to make the starch processable. The need, to provide adhesion and interaction between thermoplastic starch and LDPE, citric and stearic acid were considered as compatibilizers. To accelerate the degradation of the LDPE matrix, three pro-oxidants cobalt(II) acetylacetonate, iron(III) stearate and manganase(II) stearate were used. The films prepared were characterized by FTIR spectroscopy their thermal and mechanical properties were analyzed and buried under soil. The films recovered from soil after 76 days were characterized by FTIR spectroscopy, their weight loss were measured and their thermal and mechanical properties were analyzed. Studies showed that the use of cobalt(II) acetylacetonate gave improved results in terms of the mechanical properties and thermal stabilities of the films. Additionally, it is observed that the use of citric acid as a compatibilizer improved the thermal stabilities of starch in the films. Lastly, it is observed that the mechanical properties of the films were affected by the interactions between compatibilizers and pro-oxidants.

Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia Strawberry is an important horticulture crop which is traditionally grown in raised beds covered with plastic. The high cost of removal and treatment of plastics waste led to the study with films of natural and biodegradable source. The objectives of this study were to compare the effect of two mulchs, a conventional plastic and a biodegradable film, in productivity and the incidence and severity of diseases and pests. The test was conducted in greenhouses and outdoor and weather conditions, production, fungi and insects associated with plants and soil mycobiota were monitored. The weather conditions recorded were considered normal for the production and in the different modalities production ranged from about 22t/ha outdoor and 28t/ha in the greenhouse. Related to observation of disease symptoms and isolation from tissues were identified 33 taxa of fungi, of which 10 are associated with diseases of the crop, including Botrytis cinerea, Cylindrocarpon spp. Fusarium oxysporum, Macraphomina phaseolina and Rhizopus stolonifer. In the study of soil mycobiota 14 taxa of fungi were observed. Five thrips species belonging to the genera Aeolothrips, Frankliniella, Melanthrips and Thrips were found. There were no significant differences between the types of cover for any of the parameters studied.

Mestrado em Engenharia Agronómica - Instituto Superior de Agronomia The main goal of this study was comparing traditional low density black polyethylene plastic mulch (25μm) with three different starch based biodegradable mulch films (15μm), on a muskmelon “Lusitano” (Cucumis melo var. inodorus). The mulch film layout and crop plantation, soil temperature and humidity, weeds, canopy spread area, flowering and yield and crop quality were monitored. The field trial was conducted in Azeitada – Almeirim (from April to July 2011) with a completely randomized experimental design with three replications, 25 plants each. The mulch films modalities were: PE (control), BMF1 (black biodegradable plastic film Mater-Bi®-CF04P); BMF2 (black biodegradable plastic film Mater-Bi®-CF04P with recycled material) and BMFV (green biodegradable plastic film Mater-Bi®-CF04P). The results showed the adaptability of biodegradable mulch films to climatic conditions and traditional techniques applied, not observing significant differences in fruit quality and production. Regarding the soil water content the BMF1 showed higher values when compared with BMFV, as well as BMFV compared with PE. The soil temperatures were similar in all the modalities and PE and BMFV had precocious flowering and production. A positive correlation between initial growth (36DAT) and the soil growing degree-days (temperature 10ºC) accumulated was obtained, and also between initial growth and final yield.

Thesis (MScAgric)--Stellenbosch University, 2012. ENGLISH ABSTRACT: An investigation into the effects of different mulches on the root environment, encompassing physical, chemical and biological factors of the soil, on two different soil types was done in the form of a field trial on ‘Cripps’ Pink’ apples. Three organic mulches were tested: compost, vermi-castings and woodchips, as well as an inorganic mulch, geotextile fabric, and were compared against clean cultivation. The organic treatments resulted in improved physical conditions (lower bulk densities) in the heavier soil, as well as, a reduction in temperature fluctuations and a general increase in soil temperatures during the seasons, in both sites. The geotextile fabric treatment resulted in increased soil moisture levels in the top 40 cm, predominantly in the heavier soil. The compost treatment resulted in high soil moisture levels in the top 40 cm only in the lighter soil. The vermi-castings treatment achieved superior results in terms of changing the nutrient status of the heavier soil. It resulted in significantly higher pH, P (phosphorus), N (nitrogen), K (potassium), Mg (magnesium), Zn (zinc), Mn (Manganese), B (boron), as well as the cation exchange capacity and some exchangeable cations, such as, Na+ (sodium ions), K+ (potassium ions) and Mg+ (magnesium ions). The compost treatment resulted in significantly higher Ca (calcium) and Ca+ (calcium ions) in the heavier soil compared to the other treatments. The organic mulches, including the woodchips treatment, consistently resulted in higher mineral levels and therefore performed the best in this regard and did so in the heavier soil. In contrast to the heavier soil, none of the treatments were successful in ameliorating the nutrient status of the lighter soil, with the exception however of the increased percentage C as a result of the compost and vermi-castings treatments. The compost treatment realised consistently higher mychorrizael colonization in both sites, however, not always significantly higher than the other treatments. The vermi-castings treatment realised consistently lower plant parasitic nematodes numbers. Higher free-living nematodes were also frequently realised during both seasons and in both sites. The organic mulches therefore proved promising with regard to soil biota. The organic treatments, with the exception of the vermi-castings treatment, resulted in improved root number and distribution in the heavier soil. The vermi-castings treatment resulted in a superior root environment and did not need to enhance its root system in order to achieve good fruit yield and quality. In contrast, the geotextile fabric treatment performed better in this regard in the lighter soil. The geotextile fabric treatment also achieved the lowest weed counts, quantified as winter weeds, in both sites. Yield efficiency, in the heavier soil, and the incidence of sunburn in both sites, were influenced by mulching. In the heavier soil, the woodchips treatment resulted in the highest yield efficiency and the compost treatment consistently resulted in the highest incidence of sunburn. In the lighter soil the control treatment resulted in the highest incidence of sunburn. The vermi-castings treatment consistently resulted in lower incidences of sunburn. Due to the limited quantification of irrigation in this trial, the consequence of irrigation on different mulches was not evaluated and should be considered for future research. AFRIKAANSE OPSOMMING: ‘n Ondersoek na die effek van verskillende deklae op die wortelomgewing, insluitende fisiese, chemiese en biologiese grond faktore, is uitgevoer as ‘n veldproef of twee verskillende grondtipes, op ‘Cripps’ Pink’ appels. Drie organiese deklae is ge-evalueer naamlik: kompos, ‘vermi-castings’ en houtspaanders, asook ‘n anorganiese geotekstiel materiaal deklaag, en vergelyk met ‘n kontrole van skoon bewerking. Die organiese behandelings het verbeterde fisiese kondisies (laer bulkdigtheid) in die swaarder grond, asook ‘n verlaging in temperatuur fluktuasies en algemene verhoging in grondtemperature gedurende die seisoene in beide persele tot gevolg gehad. Die geotekstiel behandeling het verhoogde grondvog-vlakke in die boonste 40 cm in beide persele tot gevolg gehad, alhoewel dit meer prominent in die swaarder grond was. In sanderige grondperseel, het die kompos behandeling hoër grondvog-vlakke in die boonste 40 cm getoon as die ander behandelings. Die ‘vermi-castings’ behandeling het die beste resultate in terme van verbetering van nutrient- vlakke in die swaarder grond behaal. Dit het ‘n betekenisvol hoër pH, P (fosfaat), N (stikstof), K (kalium), Mg (magnesium), Zn (sink), Mn (mangaan), B (boron), katioon uitruilings kapasiteit en sommige uitruilbare katione soos , Na+ (natrium ione), K+ (kalium ione) en Mg+ (magnesium ione) as die ander behandelings in die swaarder gehad. Die kompos behandeling het betekenisvol hoër Ca (kalsium) en Ca+ (kalsium ione) in die swaarder grond getoon. Die organiese behandelings, insluitend die houtspaander behandeling, het dus in die geval, konstant die beste resultate te opsigte van hoër nutriënt vlakke in die swaarder grond getoon. Inteenstelling met die swaarder grond, het geen behandling daarin geslaag om die grondvoedingstatus van die sanderige grond te verbeter nie, met uitsondering die verhoogde persentasie C as ‘n resultaat van die kompos en ‘vermi-castings’ behandelings. Die kompos behandeling het konstant hoër mychorriza-kolonisasie teweeg gebring in beide persele, alhoewel nie altyd betekenisvol hoër as die ander behandelings was nie. Die ‘vermicastings’ behandeling het konstant ‘n laer persentasie plant-parasitiese nematodes getoon. Meer vry-lewende nematodes het ook gereeld oor die totale vier jaar wat die volledige proef gestrek het, op beide persele, voorgekom. Die organiese deklae toon dus belowende resultate in terme van biota. Die organiese behandelings, met uitsondering van die ‘vermi-castings’ behandeling, het verhoogte wortel ontwikkeling en -verspreiding in die swaarder grond tot gevolg gehad, Die ‘vermi-castings’ behandeling het ‘n besondere goeie wortelomgewing geskep en ‘n verbetering in die wortelstelsel om ‘n goeie opbrengs en kwaliteit te behaal, was nie nodig nie. Daarinteen het die geotekstiel behandeling beter resultate in die meer sanderige grond behaal. Die geotekstiel behandeling het ook die laagste onkruidstand in beide persele gehad. Opbrengs, in die swaarder grond, en die voorkoms van sonbrand in beide persele, is beïnvloed deur die dekgewasse. In die swaarder grondperseel het die houtspaanders behandeling die hoogste opbrengs getoon en die kompos behandeling, konstant die hoogste voorkoms van sonbrand. In die ligter, sanderige grondperseel, is die hoogste sonbrand voorkoms gemeet in die kontrole behandeling. Die ‘vermi-castings’ behandeling het die laagste sonbrand voorkoms getoon. Weens die beperkte kwantifisering van die besproeiing in die proef, is die gevolge van besproeiing op verskillende deklae nie ondersoek nie en behoort dit oorweeg te word in toekomstige navorsing.

Abstract (sommario):

Biodegradable mulch may offer the benefits of polyethylene mulch for crop production with the added benefit of biodegradability. Four studies were carried out in Mount Vernon, WA to evaluate biodegradable mulch for tomato (Solanum lycopersicum L.) and broccoli (Brassica oleracea var. italica) production. The first study compared four biodegradable mulch treatments: BioAgri, BioTelo, WeedGuardPlus (cellulose product), and SB-PLA-10/11/12 (experimental, non-woven fabric), to polyethylene mulch and bare ground in high tunnels and in the open field for tomato yield and fruit quality over three growing seasons. Biodegradable plastic films produced yields and fruit quality comparable to polyethylene. Moreover, high tunnels increased total and marketable fruit weight five and eight times, respectively, compared to the open field. The second study quantified relationships among visual assessment parameters and mulch mechanical properties. Visual assessments and mechanical property tests of polyethylene, BioAgri, BioTelo, WeedGuardPlus, and SB-PLA-10/11/12, were made over three growing seasons. Regression analyses found the strongest relationship overall (r2 = 0.41) to be between the percent of initial breaking force in the machine direction and log 10 of percent visual deterioration. However, evaluating mulch products individually and increasing sample frequency are recommended for future research. The third study evaluated three biodegradable mulch products, BioAgri, Crown 1, and SB-PLA-11, after soil-incorporation. The average area of recovered mulch fragments decreased for all mulch products over time. The number of mulch fragments initially increased for all mulch products, with the greatest number of Crown 1 and BioAgri fragments recovered 132 and 299 days after incorporation, respectively. At 397 days after soil-incorporation, the total area of recovered fragments of Crown 1 and BioAgri was 0% and 34% of the theoretical maximum area, respectively. The fourth study used the diffusion of innovations framework to study perceptions about biodegradable mulch and employed the concept of "tactile space" to create sensuously rich learning environments wherein participants could interact with each other and the environment to evaluate biodegradable plastic mulch. Participants' perceptions about biodegradable mulch and attitudes toward adoption improved. Employing tactile space as a diffusion strategy may encourage non-representational learning to supplement and reinforce the knowledge claims being made at outreach/education events.

Abstract (sommario):

Mestrado em Engenharia do Ambiente - Instituto Superior de Agronomia In this dissertation, the aim was to evaluate and compare the performance of biodegradable mulch relatively to conventional polyethylene. For this purpose three different “mulches” were tested: polyethylene (PE) and two biodegradable "Short Cycle" (SC) and "Salads" (S) developed from the Mater-Bi™ matrix. Escarole (Cichorium endivia L.) crop cycle was monitored along the experimental study implemented at real scale. The monitoring plan was developed to evaluate the crop productivity and the impact of the different “mulches” in terms of moisture and soil temperature. The results achieved during this study showed the adaptability of biodegradable plastics to the soil and weather conditions, checking a significant difference in productivity of plants covered with plastic S relative to the other two modes (PE and SC). Given that to date there is no biodegradation studies in the Alentejo region of Portugal soils, it was also important to check the level of biodegradability of these new plastic films following the norm DIN EN ISO 17556. The results obtained in this work can be concluded that biodegradable plastics seem like a good solution to replace the PE, yet research and development of these new plastics should continue to hold

Abstract (sommario):

Research objective. The study was aimed to establish the competitive peculiarities of the multi-component agrocenose (maize, living mulches, weeds) and its effects on soil properties under sustainable farming conditions. Research tasks. To accomplish the research objective the following tasks were set - to study: 1. The influence of living mulches, grown in a maize monocrop, on soil physical properties (soil moisture dynamics, shear resistance, penetration resistance, soil structure and its stability), chemical characteristics (total nitrogen, available phosphorus and potassium content, pH) and biological characteristics (urease and saccharase activity); 2. The dynamics of biomass accumulation of living mulches and weeds; 3. The impact of living mulches on weed infestation in a maize crop and on weed seed contamination in a ploughlayer; 4. Maize crop irradiance conditions and their influence on different components of the agrophytocenose; 5. Projection coverage of maize inter-rows; 6. Maize productivity and biometric indicators; 7. The relationships between the factors tested. Tyrimų tikslas – įvertinti daugiakomponentės agrocenozės – kukurūzų, tarpinių augalų, piktžolių – konkurencinius ypatumus ir jos poveikį dirvos savybėms tvaraus ūkininkavimo sąlygomis. Tyrimų uždaviniai. Tyrimų tikslui pasiekti numatyta ištirti: 1. Įsėlinių tarpinių augalų, augusių kukurūzų monopasėlyje, poveikį dirvos fizikinėms (dirvos drėgnio dinamikai, šlyties pasipriešinimui, kietumui, dirvos struktūrai ir jos patvarumui), cheminėms (suminio azoto, judriojo fosforo ir kalio kiekiui, pH), biologinėms (ureazės ir sacharazės aktyvumui) savybėms; 2. Įsėlinių tarpinių augalų ir piktžolių biomasės kaupimosi dinamiką; 3. Įsėlinių tarpinių augalų poveikį kukurūzų pasėlio piktžolėtumui bei armens užterštumui piktžolių sėklomis; 4. Kukurūzų pasėlio apšvitos sąlygas ir jų poveikį skirtingiems agrofitocenozės komponentams; 5. Kukurūzų tarpueilių projekcinį padengimą; 6. Kukurūzų produktyvumo ir biometrinius rodiklius; 7. Tiriamųjų veiksnių sąsajas ir poveikio priežastingumą.

Abstract (sommario):

Agronomic research is lacking for hops (Humulus lupulus), especially in North Dakota (ND) and the northern Great Plains, where demand has risen. This research was done to evaluate factors influencing hops establishment in ND. Factors for this research were hop cultivar, mulch type, and nitrogen source. Variables measured included weed suppression, soil temperature, soil moisture, hop growth, and yield. Nitrogen source did not affect hop growth. ?Cascade? outperformed ?Mt. Hood? and ?Santiam?. Mulch type affected hop establishment, weed suppression, soil temperature, and soil moisture readings. Landscape fabric provided the greatest weed suppression and retained the most soil moisture, but also had the highest soil temperature and greatest soil temperature fluctuation throughout the day. Further research is needed to determine many other optimum growing practices for hops in the northern Great Plains. However, this research is the first field trial showing that hops can successfully be grown in ND.

Abstract (sommario):

Abstract The nuts of galvanized fasteners used on bridges are coated with a wax-based lubricant that contains a dye. Once installed, the fasteners are cleaned to remove the wax prior to painting. Cleaning is typically accomplished using a combination of solvents and hand tools, but questions are often raised as to how much residual dye on the surface is acceptable for painting. To gain better insight into this issue, the Florida Department of Transportation (FDOT) commissioned a research project to evaluate the performance of a bridge paint system applied to mechanically galvanized and hot dip galvanized fasteners after removal of various amounts of lubricant. This paper summarizes the research that was undertaken and the results.
