SHG Federations as Livelihood Support Organizations
Authors: Navin T. , Rao N. Srinivasa , Singh Shashank , Gautam Rajendra Singh
Published: March 2017

The last two decades has witnessed a phenomenal growth in the number of Self Help groups (SHGs) and SHG federations in India. There were an estimated 1, 78,664 SHG federations in India during 2013-14. SHG federations emerged as important institutions to take over the functions formerly provided by SHG promoting organizations. Placed in a situation where small size of SHGs and their limited financial and human resourcesdid not allow it to deal with larger financial and non-financial, livelihood issues affecting their women members, SHG federations were to address this gap. It was to go beyond being mere financial intermediaries to also become livelihood promotion organizations. The paper argues that while SHG Federations have emerged as financial intermediaries, its role as livelihood support organizations is still a question mark. The study looks at the role of SHG federations as livelihood support organizations.
Production System and Cultivar Effects on the Development of Skin Separation or “Silvering” in Bell Pepper Fruit
Authors: Wyenandt Christian A. , Kline Wesley L. , Ward Daniel L. , Brill Nancy L.
Published: March 2017

From 2006 to 2008, four different production systems and five bell pepper cultivars (Capsicum annuum) with either no resistance (Alliance and Camelot), tolerance (Revolution), or resistance (Paladin and Aristotle) to the crown rot phase of phytophthora blight (Phytophthora capsici) were evaluated for the development of skin separation or “silvering” in fruit at a research facility and four commercial vegetable farms in southern New Jersey. Cultivar, production system, and year, each had a significant effect on the total percentage of fruit with skin separation and marketable yield. The percentage of bell pepper fruit with skin separation was higher in both phytophthora-resistant cultivars compared with the phytophthora-susceptible cultivars across all four production systems. Marketable yield was highest when bell peppers were grown in double rows on raised beds with black plastic mulch and drip irrigation compared with bell peppers grown on single rows on raised beds with black plastic mulch and drip irrigation and bell peppers grown on single rows on raised, bare ground beds with buried drip irrigation. Marketable yields were lowest when bell peppers were grown in single rows on high, ridged beds with overhead irrigation. Results of this study suggest that the development of skin separation or “silvering” in fruit is more closely associated with genotype than type of production system.

Published: March 2017

There is a research gap with respect to documenting the effects of sweetpotato (Ipomoea batatas) seed root density and size on transplant yield and quality. Field studies were conducted in 2012 and 2014 to determine the effect of sweetpotato seed root (canner size) density [12, 24, 37, 49, 61, 73, and 85 bushels [bu (50 lb)] per 1000 ft2] on ‘Covington’ and ‘Evangeline’ slip production in propagation beds. Another field study was conducted in 2012 and 2013; treatments included canner, no. 1, and jumbo-size ‘Covington’ roots at 49 bu/1000 ft2, to determine the effect of seed root size on slip production. As seed root density increased in the propagation bed, transplant production increased with no change in slip quality as measured by node counts and slip length except for stem diameter. In 2012, the best marketable slip yield was obtained at root densities of 73 and 85 bu/1000 ft2. In 2014, marketable slip production of ‘Evangeline’ increased as seed root density increased at a greater rate than ‘Covington’. In 2014, the best seed root density for marketable slip production was 49 to 85 bu/1000 ft2 for ‘Covington’ and 85 bu/1000 ft2 for ‘Evangeline’. In 2012, potential slip revenues increased with an increase in seed root density up to 73 bu/1000 ft2. In 2014, revenue trend was similar for ‘Covington’ as 2012; however, for ‘Evangeline’, revenue was greatest at 85 bu/1000 ft2. Seed root size had no effect on marketable slip production when using a once-over harvest system. Results suggest growers would use a seed root density from 49 to 85 bu/1000 ft2 depending on variety, and any size roots for production of optimum marketable slips. Selection of optimum seed root density also depends on grower needs; e.g., high seed root density strategy will have a higher risk due to the upfront, higher seed costs, but potentially have higher profits at harvest time. Lower seed root density strategy would be a lower initial risk with a lower seed cost, but also potentially have lower net revenues.
Chemical Properties of Biochar Materials Manufactured from Agricultural Products Common to the Southeast United States

Published: March 2017

The use of biochar as a soil amendment has fostered much attention in recent years due to its potential of improving the chemical, physical, and biological properties of agricultural soils and/or soilless substrates. The objective of this study was to evaluate the chemical properties of feedstocks, common in the southeast United States, and their resulting biochar products (after being torrefied) and determine if the chemical properties were within suitable ranges for growers to use the biochar products as root substrate components. Poultry litter biochar produced at 400 °C for 2 hours had a higher total phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), chloride (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), sodium (Na), and zinc (Zn) concentration than biochar made using the same process with mixed hard wood species, miscanthus (Miscanthus capensis), cotton (Gossypium hirsutum) gin trash, switchgrass (Panicum virgatum), rice (Oryza sativa) hull, and pine (Pinus sp.) shavings feedstocks. The pH of the biochar products ranged from 4.6 for pine shaving biochar to 9.3 for miscanthus biochar. The electrical conductivity (EC) ranged from 0.1 dS·m−1 for mixed hardwood biochar to 30.3 dS·m−1 for poultry litter biochar. The cation exchange capacity (CEC) of the biochar products ranged from a low of 0.09 meq/g for mixed hardwood biochar to a high of 19.0 meq/g for poultry litter biochar. The water-extractable nitrate, P, K, Ca, Mg, sulfate, boron, Cl, Cu, Fe, Mo, Na, and Zn were higher in poultry litter biochar than in all of the other types of biochar. The high EC and mineral element concentration of the poultry litter biochar would prevent its use in root substrates except in very small amounts. In addition, the high degree of variability in chemical properties among all of the biochar products would require users to know the specific properties of any biochar product they used in a soil or soilless substrate. Modifications to traditional limestone additions and fertility programs may also need to be tested and monitored to compensate for the biochar pH and mineral nutrient availability. Users should be aware that biochar products made from different feedstocks can have very different chemical properties even if the same process was used to manufacture them.
Herbicide Applications and Incorporation Methods Affect Dazomet Efficacy on Bermudagrass
Authors: Jeffries Matthew D. , Gannon Travis W. , Reynolds W. Casey , Yelverton Fred H. , Silcox Charles A.
Published: March 2017

Turfgrass renovations commonly involve changing cultivars or species that are better suited for a given setting. Common bermudagrass [Cynodon dactylon (L.) Pers.] is a perennial turfgrass that is difficult to eradicate before renovations, and poses contaminant concerns for the subsequent stand. Dazomet is a granular soil fumigant that has activity on various pests, including common bermudagrass. Field research was conducted from 2015 to 2016 in Raleigh, NC and College Station, TX to evaluate dazomet treatments including various combinations of soil incorporation (irrigation- or tillage-incorporated) and sealing (tarp or no tarp) methods, application rates [291, 291 followed by (fb) 291, 468, or 583 kg·ha−1], and fluazifop-P [fluazifop (0.4 kg·ha−1)] + glyphosate (2.8 kg·ha−1 acid equivalent) application(s) for established common bermudagrass control. Overall, treatments required fluazifop + glyphosate before dazomet application for acceptable control (>90% cover reduction) at 42 and 46 weeks after initial treatment (WAIT) in Texas and North Carolina, respectively. Soil-incorporation results varied by location, with dazomet application (583 kg·ha−1) fb tillage resulting in ≥88% cover reduction across locations, while acceptable control from irrigation incorporation was only observed in North Carolina. Tarping did not improve efficacy when tillage incorporation at the maximum label application rate provided acceptable control, suggesting practitioners may eliminate this procedure. Information from this research will aid turfgrass managers in developing cost-effective, ecologically sound common bermudagrass eradication programs before renovations.
Student Use and Perceptions of Virtual Plant Walk Maps as a Study Tool in Plant Identification Courses
Authors: Wilson Matthew S. , Miller Chad T. , Bloedow Nicholas R.
Published: March 2017

Virtual plant walk maps were developed for an ornamental plant identification (ID) course, with the goal of providing an additional study resource to potentially enhance student learning. The maps provided students an opportunity to revisit plants covered in lecture and laboratory sections at their own convenience, using either a computer or mobile device. Each map plotted the locations of the plants from the corresponding list and provided photographs of specimens, plant family, common and scientific names, and plant type information. At the end of the course, a survey was given to collect information about student use and perceptions of the virtual plant walk maps for two fall semesters (n = 87). Survey results indicated 63% of the students used the virtual plant walk maps as a study resource. Students who used the maps reported accessing the maps an average of 3.2 times between receiving the maps and taking the plant ID quiz in laboratory. Students mainly used the maps to study the most current plant list and accessed previous plant list maps to a lesser extent. About 67% of students who used the virtual maps, used the maps to visually review the plants online only, although 31% of students used the maps for both visual review and to physically retrace the plant walk to view the live specimens. Of the students who did not use the maps, most found other study resources/methods more useful or they forgot about the maps as a resource. When asked to rate usefulness of the maps on a scale from slightly useful (1) to very useful (3), 43% of students indicated that the virtual maps study tool was very useful, 25% indicated the maps were useful, and 8% indicated that the maps were slightly useful. A significant dependence between student use frequency and student usefulness ratings of virtual plant walk maps was observed. As students’ use of the virtual maps increased, they perceived the maps to be more useful to their studies in preparing for ID quizzes. No differences between plant ID quiz scores were associated with virtual plant walk map use, learning style, or use by learning style. Our survey indicated that students used the virtual plant walk maps as a resource and perceived the maps as a useful tool in preparation for ID quizzes.

Agriculture is fundamental to meeting Americans’ basic needs—clothing, housing, and food. As the average farmer’s age increases, there is a need to develop programs to encourage youth to pursue careers in agriculture and become the next generation of farmers. This study developed and implemented a horticultural curriculum focusing on vegetable production at a summer camp setting. Targeted participants were aged 9 to 12 years. Pre- and posttests were given to both the treatment group (campers participating in the victory garden track) and the control group (campers participating in a Wetlands track). The pre- and posttest evaluated campers’ science-based knowledge and confidence. The study was replicated 16 times (weeks) over a 2-year study. Lesson topics included propagation, victory gardens, soil, recycling, plant parts, pollination, photosynthesis, and insects. Campers in the treatment group had improvement of general horticulture knowledge from pretest to posttest responses 18% improvement in 2010 and 11% improvement in 2011. Posttest scores of treatment campers were greater 20% in 2010 and 16% greater in 2011 (P ≤ 0.05) than control campers in both years of the study. Treatment campers were more confident (P ≤ 0.05) in explaining to others how to grow a plant and in their ability to grow more than one type of plant. Analysis of the 2nd year of data-indicated treatment campers were more likely (P ≤ 0.05) to feel confident in their ability to plant a seed that would later grow into a plant.
Retail Promotion and Advertising in the Green Industry: An Overview and Exploration of the Use of Digital Advertising
Authors: Barton Susan S. , Behe Bridget K.
Published: March 2017

The retail portion of the green industry, valued at $50.55 billion, continues to provide a major connection between the industry and consumers. Given the importance of retailers in the green industry and little research exists that documents their advertising practices and impacts, the 2013 Trade Flows and Marketing Practices survey included questions to capture data for retail-only firms. This paper reports on the percentage of sales retailers allocate to promotion and advertising, including a breakdown of media used; point-of-sale (POS) materials and how they are acquired; how green industry retailers are using social media and mobile marketing [in particular, quick response (QR) codes]; the methods retailers use to collect customer demographics; customer loyalty programs (CLP); and how they are managed by retailers and a comparison of retail firms’ advertising practices by size of firm. A combination of mailed and Internet-distributed surveys resulted in a total of 699 useable retail business responses with greater than or equal to $1000 in annual revenue. The median expenditure as a percentage of sales on advertising was 3.6% for all retail firms responding with 33.7% spending no dollars on advertising. In examining the distribution based on media type, the Internet was the most frequently listed by firms (32.3%) with a mean expenditure of 42.5% of total advertising dollars. Social media was listed second most frequently (21.5%) with a mean expenditure of 29.6%. Newspapers were listed as the third most frequently used type of media (18.0%). Social media use is strong and among social media platforms, Facebook (60%) far exceeds any other platform. A third of the respondents (34.2%) reported the use of POS materials. A very small percentage of firms (3.0%) reported using QR codes and 19.4% reported having a CLP. Of those, 45.8% used customer purchase cards, whereas 35.4% used POS software. Nearly 33% of the firms collected demographic information about their customers. Of those, the method with the highest percentage use (multiple responses were permitted) was social media (50.7%) followed by CLP (48.9%), web visits (34.5%), questionnaires (15.7%), social coupons (13.5%), census data (3.9%), and marketing firms (3.1%). There were firm-size differences in seasonal employees and mean sales per employee with large firms having greater numbers than hobby, small- or medium-sized firms. There were no differences in the percentage of advertising media allocations based on firm size, but large firms used web visits, social coupons, and social media more than other types of firms to collect customer demographics. While, green industry retailers are currently using social media for marketing green industry goods, they have much more opportunity to use electronic media for CLPs and to begin using QR codes or other mobile-centric technologies to deliver in-store promotional information to consumers.
Optimum Seasonal Mowing Heights for Smooth Crabgrass Reduction in Tall Fescue Lawns
Authors: Cropper Kenneth , Munshaw Gregg , Barrett Michael
Published: March 2017

Cultural control methods for pest management are desirable as they can reduce pesticide use resulting in reduced costs and environmental impact. Previous research has shown increased mowing heights can reduce crabgrass (Digitaria sp.) populations. However, seasonal mowing height adjustments may further decrease crabgrass populations as lower heights of cut can increase turf density during optimal growing conditions. An experiment was conducted to determine ideal mowing height combinations during summer vs. fall/spring for crabgrass reductions in a tall fescue (Festuca arundinacea) sward. A half rate of prodiamine was included as a split-plot treatment to determine if mowing height combinations could reduce the amount of pesticide required to control crabgrass. Four fall/spring mowing heights (1, 2, 3, and 4 inches) were combined with the same summer mowing heights such that all heights were represented in both seasons. Results indicate that seasonal mowing height variations did not provide any better reduction in crabgrass populations over only using higher heights of cut consistently throughout the year. Also, the half rate of prodiamine successfully controlled crabgrass in all mowing heights except the lowest mowing height during summer months.

Considering the potentials of wild rice (Oryza spp.), as well as the need to enhance the yield potential of rice and to increase rice production to meet increasing demands, 1780 backcross inbred lines (BILs) were generated by crossing 70 accessions of six “AA” genome species: Oryza glaberrima Steud., Oryza barthii A. Chev., Oryza nivara Sharma & Shastry, Oryza rufipogon Griff., Oryza longistaminata A. Chev. & Roehr., and Oryza glumaepatula Steud. with two elite cultivars of Oryza sativa L. The wild species accessions were selected based on variation at the DNA markers and agromorphological traits. The BILs were generated by backcrossing F1s twice (thrice in some cases) to recipient parents, followed by continuous selfing and selection for the yield and yield component traits. The set of 1780 BC2F5 to BC2F10 BILs were evaluated in an augmented design over 3 yr. Based on ANOVA in augmented design, 108 agronomically superior BILs were selected and evaluated in randomized complete block design. Of the 108 BILs evaluated, 15 BILs showed >10% yield superiority over the recurrent parent, with spikelet per panicle and thousand‐grain weight as most significant traits contributing to yield increase. Based on the contribution of donor accessions for the improvement of yield component traits, six accessions of O. glaberrima, one of O. barthii, two of O. nivara, two of O. rufipogon, and one each of O. longistaminata and O. glumaepatula were identified as potential donors that could be used more rigorously in transferring genes to cultivated rice. The BILs generated in the present study represents a reservoir of novel genetic variation.
A Simple Package to Script and Simulate Breeding Schemes: The Breeding Scheme Language
Authors: Yabe Shiori , Iwata Hiroyoshi , Jannink Jean‐Luc
Published: March 2017

It is difficult for plant breeders to determine an optimal breeding strategy given that the problem involves many factors, such as target‐trait genetic architecture and breeding‐resource availability. There are many possible breeding schemes for each breeding program. Although simulation study may be useful to help choose a better (or the best) breeding scheme, it is difficult for breeders to take the first step in conducting breeding simulation because of the complexity of building a simulation platform or even using existing simulation tools. We present here a simple and flexible simulation platform, the breeding scheme language (BSL). This simulation platform works in the statistical computing environment R. Users define their target species, trait genetic architectures, and breeding schemes by writing simple, self‐explanatory scripts. We believe the BSL will be useful for breeders to evaluate breeding schemes and to choose an optimal breeding strategy among a number of possible ones, as well as for training plant breeders.

According to the Institute of Healthcare Improvement, “human factors” refers to the discipline of engineering that details the interface of people, equipment and the environment in which they work. Issues that impact human performance and increase the risk of error include factors that directly enable decision making, such as perception, attention, memory, reasoning, judgement and factors that directly enable decision execution, such as communication and the ability to carry out the intended action.
Fetoscopic Laser Coagulation in Twin-Twin Transfusion Syndrome: Case Series
Authors: Yucel Aykan , Uygur Dilek
Published: March 2017

Twin-to-twin transfusion syndrome is a fatal complication and twins with monochorionic/diamniotic placentas are affected due to placental vascular anastomoses, producing volume transfer of blood from one twin to the other. The donor twin becomes hypovolemic with oligohydramnios and the recipient becomes hypervolemic with polyhydramnios. Twin-to-twin transfusion syndrome is associated with increased perinatal morbidity and mortality and expresses longstanding health hazards. Serial amnioreduction and fetoscopic laser photocoagulation of the vascular anastomoses are the main therapeutic approaches for twin-to-twin transfusion syndrome. Higher survival rates after fetoscopic laser ablation of the anastomotic vessels in comparison to serial amnioreduction have been reported in multicenter randomized clinical trials. We report the fetoscopic laser coagulation of three twin-to-twin transfusion syndrome cases at Ankara Dr. Zekai Tahir Burak Health Practice Research Center, Perinatology Clinics.

Biosorption of Copper (II) from Aqueous Solutions by Sclerotiogenic Aspergillus oryzae G15
Authors: Long Dan‐Dan , Wang Qi , Han Jian‐Rong
Published: March 2017

This study aimed at investigating the biosorption of copper(II) from aqueous solutions by sclerotiogenic Aspergillus oryzae G15. Potentiometric titration analysis results indicated that carboxyl group was mainly responsible for Cu(II) adsorption. Sclerotia were a better biosorbent than mycelia, which could be ascribed to the higher amount of carboxyl sites exposed after differentiation. Langmuir isotherm model fitted well the absorption process of mycelia and sclerotia with the maximum theoretical sorption capacities of 35.34 and 73.53 mg/g, respectively. Scanning electron microscopy coupled with energy dispersive X‐ray analysis confirmed that there was surface biosorption of Cu(II) on the adsorbents. Based on the fourier transform infrared spectroscopy analyses results, it could be proposed that the increased sorption capacity of sclerotia was due to increased functional groups related to the biosorption process. Cu(II)‐loaded biosorbents could be regenerated and reused, which indicated that A. oryzae G15 could be considered as an alternative for removing Cu(II) from wastewater.
Why is the Groundwater Level Rising? A Case Study Using HARTT to Simulate Groundwater Level Dynamic
Authors: Yihdego Yohannes , Danis Cara , Paffard Andrew
Published: March 2017

Groundwater from a shallow unconfined aquifer at a site in coastal New South Wales has been causing recent water logging issues. A trend of rising groundwater level has been anecdotally observed over the last 10 years. It was not clear whether the changes in groundwater levels were solely natural variations within the groundwater system or whether human interference was driving the level up. Time series topographic images revealed significant surrounding land use changes and human modification to the environment of the groundwater catchment. A statistical model utilising HARTT (multiple linear regression hydrograph analysis method) simulated the groundwater level dynamics at five key monitoring locations and successfully showed a trend of rising groundwater level. Utilising hydrogeological input from field investigations, the model successfully simulated the rise in the water table over time to the present day levels, whilst taking into consideration rainfall and land changes. The underlying geological/land conditions were found to be just as significant as the impact of climate variation. The correlation coefficient for the monitoring bores (MB), excluding MB4, show that the groundwater level fluctuation can be explained by the climate variable (rainfall) with the lag time between the atypical rainfall and groundwater level ranging from 4 to 7 months. The low R2 value for MB4 indicates that there are factors missing in the model which are primarily related to human interference. The elevated groundwater levels in the affected area are the result of long term cumulative land use changes, instigated by humans, which have directly resulted in detrimental changes to the groundwater aquifer properties.
Empresas do comércio “em grosso” na economia de Goiânia, cidade em formação (1933-1963)
Authors: Maciel Dulce Portilho
Published: March 2017

Este texto refere-se aos primeiros trinta anos de Goiânia, cidade fundada em 1933, para servir de capital ao estado de Goiás (Brasil). A pesquisa que o fundamenta tomou como modelo de classificação das atividades comerciais o Censo brasileiro de 1950, que desdobra o comércio “em grosso” em dois ramos: o atacadista em si e o misto, este, composto por estabelecimentos que atuam tanto no atacado como no varejo. A pesquisa revela um vigoroso desempenho do comércio misto, comparativamente ao atacadista. Atribuímos o maior êxito do primeiro ao fato de a área varejista deste voltar-se para o abastecimento da própria cidade de Goiânia, cujo aumento populacional e modernização dos costumes têm produzido, localmente, uma demanda por mercadorias sempre em excepcional crescimento.

Permasalahan pendidikan di Indonesia khususnya di Kabupaten Bantul salah satunya adalah kurang meratanya penyebaran guru-guru khususnya pada keahlian tertentu, misalkan guru IPA. Di satu sisi, ada tuntutan keprofesional guru-guru artinya guru adalah faktor penentu keberhasilan proses pembelajaran yang berkualitas, sehingga berhasil tidaknya pendidikan mencapai tujuan selalu dihubungkan dengan kiprah para guru. Oleh karena itu, usaha-usaha yang dilakukan dalam meningkatkan mutu pendidikan hendaknya dimulai dari peningkatan kualitas guru. Guru yang berkualitas diantaranya adalah mengetahui dan mengerti peran dan fungsinya dalam proses pembelajaran. Tapi disisi lain, guru dituntut untuk mengerti dan memahami sesuatu yang bukan latar belakangnya. Ironis memang ...Salah satu solusi terkait dengan permasalahan di atas, walaupun bukan solusi yang terbaik adalah memberikan pelatihan berupa praktikum IPA bagi guru-guru SD yang tidak memiliki latar belakang IPA. Bentuk praktikum ini menyesuaikan dengan jenis percobaan yang ada di SD, yaitu sederhana dan bisa dilakukan oleh siswa sendiri. Selain  Ada 8 jenis percobaan yang dilakukan, 6 diantaranya bersesuaian dengan materi IPA SD dan sisanya cenderung bersifat edutainment berbasis pemanfaatan limbah.Evaluasi yang dilakukan selama kegiatan PPM ini terdiri dari 2 bentuk, yaitu evaluasi kinerja yang dilakukan oleh tim PPM dan evaluasi berupa kuisioner yang diisi oleh peserta guru-guru. Dari evaluasi kinerja, peserta yang guru-guru SD sangat antusias mengikuti kegiatan pelatihan ini dengan rata-rata nilai aktivitas 83,3 masuk dalam kategori baik. Sedangkan dari kuisioner yang diberikan oleh guru-guru, pelatihan sejenis sangat diperlukan untuk menambah pengalaman dan pengetahuan khususnya praktikum IPAKata kunci: pelatihan praktikum IPA, proses pembelajaran IPA

It is well known that rapid growth of population and population augmented industrialization has become a horrible threat for our environment causing the decline of forestry resources. We propose a mathematical model to study the effect of population and population density dependent industrialization on forestry resources. It is assumed that the industrialization grows logistically but its growth is further enhanced due to over population. It is shown that if the population and associated industrialization increase, the density of forestry resources decreases. Numerical simulation has also been conducted to support the analytical findings.
