Pawan Gyawali | Pankaj Gyawali | Bishnu Bilas Adhikari | Dharma Raj Katuwal
A field experiment was conducted at the Agronomy farm of Nepal Agricultural Research Council (NARC), Khumaltar, Lalitpur to evaluate the effect of sowing dates and seed rates on yield and yield attributes of wheat. The experiment was laid in a split-plot design with three replications treated with 4 sowing dates as the main plot factor (12th Nov, 27th Nov, 12th Dec, and 27th Dec) and 4 seed rates as subplot factor (100 kg ha-1, 120 kg ha-1, 140 kg ha-1 and 160 kg ha-1). Results revealed that the leaf area index was significantly affected by sowing dates and was comparatively superior in 2nd sowing date (27th Nov) wheat. Similarly, in the case of seed rates, the leaf area index was influenced significantly and was recorded to be increasing with an increase in seed rates. Phenological parameters like days to 50% heading, flowering, and maturity were observed maximum (116, 123, and 179 days, respectively) in early sown wheat and reduced with the subsequent delay in sowing. Maximum values of yield and yield attributes like effective tillers per meter square (635.6), spike length (9.56 cm), grains per spike (41.49), grain yield (7.59 Mt ha-1), and straw yield (9.58 Mt ha-1) were observed in the wheat sown in 2nd date (on 27th Nov) which differed significantly to wheat sown on other dates. Seed rates had no significant influence on grain yield and yield attributes. Thousand-grain weight was found maximum (46.26 g) in early sown wheat (on 12th Nov sown wheat, reduced with the subsequent delay in sowing, and the harvest index was observed as maximum (0.51) under December 27 sown wheat. Though the yield and its attributes were not influenced significantly by seed rate, the maximum yield (6.18 Mt ha-1) was observed in wheat sown at the rate of 120 kg ha-1. Considering seed yield and its parameters, 2nd date of sowing wheat (27th Nov) and seed rate of 100 kg ha-1 could be the best option to uplift the productivity of wheat in rainfed lowland conditions of Lalitpur, Nepal.

Air pollution can be defined as the accumulation of gas, air, or particulate matter released as a result of fuel residues and chemical processes in the atmosphere in amounts that harm the lives of living things. Rapid urbanization, industrialization, increase in the number of motor vehicles, meteorological conditions, fuels used for heating, and the spread of industrial establishments and thermal power plants play an important role in the increase in air pollution. Air pollution is a major environmental problem affecting people in both developed and developing countries, and it is estimated that megacities in developing countries, and a quarter of the world's population are exposed to unhealthy concentrations of air pollutants. People living in cities with high outdoor air pollution are more likely to suffer from heart disease, respiratory problems, and lung cancer than those living in urban areas with clean air. In the industrialized western world, urban air pollution is in some respects in its final stages, with a dramatic decline in SO2 and soot levels. The increase in the number of private vehicles is a newly emerging problem. Rapid urbanization in most developing countries has so far led to uncontrolled growth and environmental degradation. Air pollution levels are still rising in many cities. In this study, air quality was tried to be measured along Dr. Sami Yağız Street, which is one of the most heavily used areas of Niğde. H2S, O2 and CO measurements were made at 25 points at equal intervals on both sides of the street. Measurements were made at a total of 4 different time periods per day. The obtained values were transferred to ArcGIS 10.3 software and maps were produced. Measurement of gases other than H2S is not distributed homogeneously along the street, and traffic density and the businesses on the sides of the street cause changes in the rates of the gases.

Yam (Dioscorea spp) occupies an important place in the diet of the populations of Côte d’Ivoire. It is a real source of starch and therefore generates enormous commercial potential. However, the decrease in production due to pest attacks represents a real threat to this crop. This study was conducted with the aim of improving yam production in Côte d’Ivoire. To do so, isolations carried out on yam leaves showing symptoms of foliar diseases have allowed us to identify 9 fungal genera. These were Colletotrichum sp., Fusarium sp., Pestalotiopsis sp., Pestalotia sp., Botryodiplodia sp., Aspergillus sp., Mucor sp., Curvularia sp. and Phytophtora sp. Among these fungi, the genus Colletotrichum sp. was the most isolated with a rate of 56% followed by the Fusarium and Pestalotia genera (8%). Pathogenicity tests performed on healthy leaves of two yam varieties revealed that the Dioscorea alata is more susceptible to fungi compared to Dioscorea rotundata. The largest average diameter of necrosis was caused by Pestalotiopsis sp. (5.97 cm) on the Dioscorea alata variety while the smallest was caused by Colletotrichum sp.9 on Dioscorea rotundata (0.5 cm). Combatting these fungi need to be developed for effective management of leaf diseases of yam in Côte d’Ivoire.

In this study, the insecticidal effect of the Detech® (Turkish Diatomaceous earth) DE formulation against Galleria mellonella L. was determined. The study was conducted in a laboratory environment with materials taken from beehives produced at Muş Alparslan University in 2022. Diatomaceous earth (DE) was applied in two different forms (dust and slurry DE) and as positive control GüveSavar®, which is currently used against some pests in beekeeping. DE concentrations of 0, 3, 5, and 7 g/m2 in different exposure times were tested for the control of G. mellonella larvae. As a result of all treatments, the highest mortality occurred at 7 g/m2 dust DE concentration. Larvae (3rd stage) exposed to 7 g/m2 concentration according to dust DE mortality rates reached 100% mortality after 40 hours. According to the results of the slurry DE, the larvae exposed to the slurry diatom at all concentrations achieved 100% mortality at the end of the 96 hours. When the dust and slurry DE results were examined, the direct use of dust formulations greatly accelerated the effectiveness against larvae. The study showed very promising results, suggesting that slurry DE and dust formulations could be a new alternative control method for Greater Wax Moth. In addition, for the first time, the insecticidal efficacy of DE against the honey bee pest, the greater wax moth, was determined.

Foliar supplementation may be useful for boron to a crop when its demands are higher compared to the supply from soil. Boron is an important micronutrient which had a substantial impact on oil content, seed yield, and the components of the sesame yield. A field investigation was implemented to determine the impact of foliar application of boron on seed yield, growth and oil content of sesame cv. BARI Til-4. The investigation included four concentrations of boron viz. 0, 25, 50, and 75 ppm and three frequencies of boron application viz. one time at 30 days after sowing (DAS), two times at 30 and 50 DAS, and three times at 30, 50, and 70 DAS. The experiment was conducted following randomized complete block design, which was replicated thrice. At the vegetative stage, the highest plant height (107.3 cm), branches/plant (5.0) and shoot dry weight (45.20 g/plant) resulted in 75 ppm boron spray at 30, 50 and 70 DAS. However, the highest root dry weight (5.80 g/plant) was recorded in 75 ppm with one application of boron at 30 DAS. The plants with the highest plant height (112.1 cm), branches/plant (5.13), pods/plant (44.13), seeds/pod (54.33), seed yield (609.0 kg/ha), harvest index (30.65%), and oil content (42.33%) were also observed with the combination of 75 ppm boron spray with thrice application at 30, 50 and 70 DAS. The lowest seed yield (368.7 kg/ha) resulted in without boron application. Therefore, it can be inferred that the most efficient method for increasing the sesame seed yield and oil content is thrice (30, 50, and 70 DAS) foliar spraying of 75 ppm boron.

Varroa destructor mite poses a serious problem for the future of bee populations around the world. Today, there are many commercial drugs with the same and different active ingredients on the market to chemically control over of Varroa destructor. More frequent chemical applications for against Varroa destructor increases stress resilience, colony losses, loss of yield and residue problems in bee products. The scope of this project is aimed to determine the appropriate control method of Varroa by investigating the efficiency values of the evaporation and dropping methods of Oxalic acid. Experimental area were chosen three different apiaries. 28 colonies were determined in each apiary and equalization studies (area with brood, number of bees with bees, age of queen bees, honey, pollen, etc.) were carried out in these colonies. The determined colonies were randomly divided into 4 groups as 7 colonies. The first group is the control group, the second group is applying 2 g of oxalic acid by vaporizing, the third group is 4% oxalic acid 5 ml of sugar syrup (1:1) is dropped between the frames, and in the fourth group, the fight against a drug that is determined by the beekeeper in the market without interfering with the beekeeper. In order to evaluate the data, samples were taken for four periods, before and after spraying in spring and autumn. While the varroa measurements in the group of syrup, vapor and spraying were found to be statistically less than the control group, the syrup, vapor and spraying groups were statistically similar in terms of varroa measurements. Oxalic acid syrup application showed higher efficiency in spring and autumn than vapor application. There is no statistically difference between both two-application method reveals that it can be used as an effective and safe alternative to chemical control against varroa.

Throughout history, there has been a reciprocal relationship between humans and space. Even though there are numerous spaces covered by this ongoing relationship process, it has integrated and gained value with educational venues. Mainly because they closely monitor social, cultural, technological, and economic developments and pass on knowledge to future generations, educational spaces play a crucial role in the development of individuals as well as society. It is feasible to conclude from research on educational spaces that the physical environment has a major positive or negative impact on education. To solve the issue that the current Faculty of Fine Arts at Selçuk University could not sufficiently respond to user needs physically, it was decided to construct a new Faculty of Fine Arts building. The primary goal of the study is to design the building using user-oriented techniques that promote social interaction and showcase artistic identity throughout the design phase. A qualitative research approach, based on inspection and observations, was used in the study to gather data, documents, and reports on the topic and to ensure that the architectural programming stages advanced correctly and received ongoing feedback. Studies have confirmed the results, which show that artistic education in structures that provide users with distinct experiences is different from that provided in faculty buildings with a type plan scheme. The process, which involves collaboration between stakeholders from various disciplines and necessitates coordination, is also maintained in a coordinated fashion as a consequence of the study. Because of this, it is believed that buildings with comparable features can offer direction by offering a set of data that may also be reliable for design procedures that are prearranged.
