Effect of Giving Arbuscular Mycorrhizal Fungi (AMF) and Bioactivator Dosage of Trichoderma spp. on the Growth and Products of soybeans (Glycine max L. Merr.)

Several factors become an obstacle to increasing soy production and achieving quality standards for soybean yields, including limited water, especially in rain-fed areas, that determine the success of soybean cultivation. The use of Trichoderma spp. Bioactivators and AMF can be a solution for adding organic material to soy cultivation. This study aims to investigate the effect of AMF and the bioactivator Trichoderma spp. on growth, yield in soybeans (Glycine max L. Merr,). The design used is a two-factor split-plot design. Because the main plot was AMF, which consisted of without and with AMF (15 g/plant). The subplot is the dosage of bioactivators (tablet and liquid form with legundi leaves fermented by Trichoderma spp.), Consisting of seven levels without bioactivators, 2.5 g tablets with bioactivators, 5.0 g tablets with bioactivators, and 7.5 bioactivators. g tablets, containing 2.5 ml liquid bioactivator, 5.0 ml liquid bioactivator, and 7.5 ml liquid bioactivator. The treatment was a combination of FMA factor and bioactivator dose, each of which was repeated three times so that there were 42 experimental units. The results showed that the administration of AMF at a dose of 15 g/plant showed better growth of the soybean plant and yielded a yield of 29.27% or 1.13 tons/ha. While the administration of Trichoderma spp bioactivator at a dose of 5.0 ml can increase the growth of soy plants and give higher yields of dry soybean seeds, namely 31.54% or 1.28 tons/ha

Determinants of Drought Tolerant Rice Variety Adoption: Evidence from Rural farm Household in Northern Part of Bangladesh

The drought-tolerant rice variety Binadhan-19 study was conducted in five districts: Mymensingh, Ranpur, Pabna, Rajshahi and Chapainwabganj of Bangladesh. A total of 200 farmers were randomly selected (40 from each location) to collect the data with a pre-designed questionnaire. Tabular, descriptive statistics and Probit model were used to fulfil objectives. The estimated log-likelihood value of gender, farm size, yield, agricultural extension services have a statistically and significant positive effect on the adoption of the variety. The household characteristic related variables such as age, experience, annual income, human labour, duration of the variety have no statistically significant effect on the adoption of the variety. Marginal coefficients indicate that if male farmers increased by 100%, the probability of adopting the Binadhan-19 variety would increase at 38 times more likely to adopt the variety. If the farm size of Binadhan-19 increased by 100%, the probability of adopting the variety would be increased by 0.07%. A farmer who has access to agricultural extension service is about 39 times more likely to adopt the variety. Again, if the yield increased by 100%, adopting the varieties would increase by 0.08%. The marginal coefficients of locations and soil fertility are negatively significant, indicating that if these two variables increased by 100%, the probability of adopting the varieties would decrease by 0.06% and 30%, respectively

Development of Bench Scale Water Treatment Unit for the Treatment of Medium Turbid Water: The Use of Natural Coagulant

Water purification is a process used to enhance water quality and make it more acceptable for specific end-use. The rising increase for portable drinking water has made natural coagulant application for water purification a welcome development. Most reported researches were on the use of natural coagulants in a laboratory batch scale. Because of those above, a bench-scale laboratory study was carried out on the application of Balanites Aegyptiaca seed as a natural coagulant. The outcome showed its usefulness toward water purification. This paper reported the developed bench-scale water treatment plant's performance utilising Balanites Aegyptiaca seed stock solution and the powdered kennel as bio-coagulant. Some design equations were adopted. The treatment units considered include coagulation/flocculation, sedimentation, and filtration. The total tank design capacity was 20 litres with the overflow area's actual size for sedimentation of 7.46 litres. 0.5 Hp electric motor with a speed of 600 rpm and a speed gear drop of 120 rpm were selected. 0.0127 m pipe flow line diameter connecting the tanks with a corresponding pipe flow velocity of 0.108 m/s was obtained from the design. However, in both the coagulation, sedimentation and filtration units, the material balance obtained showed a steadiness in the material flow across sedimentation and filtration units. However, among the parameters tested in the raw turbid water, the turbid water revealed turbidity of 514 NTU, the colour of 5600 CTU, the conductivity of 276 µs/cm, pH of 7.10 and total coliform bacteria count of 85 CFU/100 mL which were above the recommended set standard of WHO and NIS. The result of the treated water using the stock solution and the powdered kennel (bio-coagulant) on the developed water treatment unit showed a remarkable reduction in the tested parameters in the raw turbid water used for the treatment process. Total coliform count reduces from 85 CFU/100 ml to 10 CFU/ml in both cases. It was observed that conductivity increases after the treatment, but other inorganic constituents reduce significantly though not to WHO and NIS's recommended set standard. The 0-dosage treatment conducted also showed a reduction in all the tested parameters

Discovering Jewish Studies Collections in Academic Libraries: A Practical Guide

The U.S. colleges and universities offering non-sectarian educational programs in Jewish Studies rely on the support of their academic libraries for research materials and library services. For college libraries which use Library of Congress Classification scheme, it is a common practice to integrate studies resources into their general library collections. Since Jewish Studies sources span a vast number of subjects within all major disciplines, shelving integration leads to the dispersion of all relevant sources and such dispersion in turn leads to a variety of problems for library professionals and library users. For collection development librarians the problems range from lack of information about collection\u27s size, strengths or weaknesses, and for library users interested in browsing the collection, dispersion of subjects creates a major roadblock. This practical guide aims at providing a solution to such problems. By identifying all relevant Library of Congress call numbers and the corresponding Library of Congress subject headings, the guide offers a simplified access to Jewish Studies sources in general library collections. It is arranged by four major discipline: Arts & Humanities, Social Sciences, Sciences, and General Works & Bibliographies. Within each discipline, specific LC call number ranges and corresponding subjects are listed. The subjects are further subdivided and precisely identified. The guide will assist collection development librarians, library liaisons, grants and fundraising professionals and especially the Jewish Studies faculty and students, in identifying and locating relevant sources
