The effect of different organic and inorganic fertilizers had a significant effect on the yield of spring rice. A field experiment was carried out to determine the effects of different organic and inorganic fertilizers on the yield of spring rice var Hardinath-1 at Siranchowk rural municipality-4, Gorkha during the spring season of 2021 with four replications and five treatments: T1[Recommended inorganic fertilizer Nitrogen, Phosphorous, and Potassium (@100:30:30 kg/ha)], T2[75% recommended inorganic fertilizer + 25% recommended organic fertilizer: i.e. (Farm Yard Manure (6 ton /ha)], T3(50% recommended inorganic fertilizer + 50% recommended organic fertilizer), T4(25% recommended inorganic fertilizer + 75% recommended organic fertilizer ), and T5 (Recommended organic fertilizer) using simple Randomized Complete Block Design with 3*3 m of individual plot size. A biometrical observation like plant height (95.33 cm), and the number of tillers (340.75/ m2) were found significantly highest on T2. Similarly, yield attributing characteristics like the number of effective tillers (315.75/m2), several filled grains per panicle (150.25), and highest panicle length (25.06 cm) were also significantly highest on T2. The highest grain yield (8.27 ton/ha), straw yield (12.14 ton/ha), and harvest index (0.40) were also observed on T2. Total net return was found highest on T2: 287330 Nepalese Rupees(NPR) incurring the cost of fertilizer Rs NPR 18940 per hectare returning the gross return of NPR 268390 per hectare. In conclusion, T2 was the best combination of other biofertilizer combinations. So, the spring rice productivity can be enhanced via the adoption of 75% recommended inorganic fertilizer + 25% recommended organic fertilizer in fertilizer management practice at Chorkate, Gorkha.

Researchers treated seed technology and crop yield as exogenous, thereby generating bias estimates. In practice, seed technology increases yield and it’s stimulated by social capital and other factors. This paper develops a choice model of maize-seed exogenously, then tested and corrected for causality. A multistage sampling procedure was adopted using seven Agricultural Development Programme zones drawn from purposively selected Oyo and Osun states. A block each was randomly selected per zone. Twenty-one cells were randomly selected, then data were collected from 385 respondents using a structured questionnaire: Data were analyzed using Ordinary Least Square and Two-Stage Least Square α 0.05. Durbin score chi2(1) = 6.65 (p= 0.009) and Wu-Haussmann F (1,37) = 6.431 (p = 0.012), showed reverse causality that was resolved by the Two-Stage Least Square model. The Two-Stage Least Square result indicated that education (β=-0.53), seed quantity (β=-0.13), seed price (β=-0.08), negatively affected the choice of seed and yield while farm size (β=2.05), fertilizer (β=0.004), herbicide (β=0.22), output-price (β=0.02), meeting attendance index(β=0.02), and improved seed ((β=2.66), had a positive influence. Social capital spurs the use of improved seed, thereby increase maize yield. Consequently, active participation in social groups and the use of improved seed is recommended to increase yield.

This research was carried out to determine the pollination abilities of Domat, Gemlik and Sarı Ulak olive cultivars. Pollen viability rate, germination rate and amount of pollen production were examined during the periods when 25%, 50% and 75% of the flowers were opened. According to the results obtained from three years’ experimental study, the highest percentages of pollen viability were found in Gemlik (81.51%) and Domat (81.50%), whereas Sarı Ulak cultivar (77.41%) showed the lowest viability. In pollen germination percentages, the highest values on the basis of cultivars were determined 59.85% (Domat), 59.74% (Gemlik) and 52.12% (Sarı Ulak). The highest amount of pollen production in a flower was found in the Sarı Ulak cultivar (329,046) while it was followed by Domat (319,693) and Gemlik (306,385). Despite the high pollen production in Sarı Ulak cultivar, the pollen viability and germination rates were found to be low. In Gemlik and Domat cultivars, all values were obtained relatively near. In addition, it had been noted that the values related to pollen viability, germination and production amount were higher during 50% and 75% flowering periods than 25%.

A field experiment was conducted to evaluate the performance of sweet blue Lupin intercropped with maize at different planting time under irrigation in Ethiopia. For the experiment, sweet lupin (cultivar Sanabor) and Maize (cultivar PBH 3253) were used. The experiment was conducted in a randomized complete block design with four replications. The treatments were sweet lupin intercropped with maize simultaneously, 1, 2, 3, 4 and 5 weeks after maize planting. Sole maize was planted as control. Maize was planted in rows with spacing of 75 cm and 30 cm between rows and between plants, respectively. Lupin was planted between two maize rows (one maize row: two lupin row) 22.5 cm apart from maize row. The distance between lupin plants is 7 cm. In addition, maize rows were top-dressed N-fertilizer at the rate of 100 Kg ha-1 by dividing in to two at planting and at vegetative stage. Intercropping time had a significant effect on yield and yield components of sweet lupin, but not on maize. Lupin intercropped simultaneous with maize gave significantly higher dry matter and seed yield 1.05 and 1.71t/ha, respectively as compared to the four intercropping dates. Maize grain yield and maize stover yield were not affected by sweet lupin intercropping dates. This study showed that sweet lupin intercropped simultaneously with maize could be optimum sowing date for better grain and dry matter yield of sweet lupin without affecting maize grain and stover yield under irrigation condition.

A study was conducted to evaluate the effect of supplementation of alfalfa (Medicago sativa L.) hay and urea molasses block on feed intake, digestibility, and body weight change of yearling local sheep fed with grass hay as a basal diet. The rationale for supplementation of alfalfa hay with urea molasses block 1) high-producing animals protein need cannot exclusively met from rumen microbial sources; 2) protein is the most expensive nutrient of ruminant animal feed. Twenty-four yearling intact male local sheep with a mean initial body weight of 23.9±1.9 (Mean ± SD) were used in a completely randomized block design. Treatments were 1% of live weight alfalfa hay (1A), 1.5% of live weight alfalfa hay (1.5A), 2.0% of live weight alfalfa hay (2A), and all three treatments offered with 100g/head/day of Urea-molasses-block (UMB). The control treatment was supplemented with concentrate mix at 2.0% of live weight (C). In addition, all treatments were fed grass hay ad libitum. The study period consisted of 84 days of feeding and 7 days of digestibility tests. Total dry matter intake was 1015.65, 925.41, 956.16, and 1078.13 (SE=± 19.4) for C, 1A, 1.5A, and 2A, respectively and 1A was lower than 2A and similar with 1.5A and C. Apparent crude protein digestibility and Crude protein intake of 2A was statistically similar to C. But, higher than 1A and 1.5A. Average daily gain was 109.33, 54.76, 55.36, and 63.1 (SE=± 6.13) g/day for C, 1A, 1.5A, and 2A, respectively and the values were the highest for C. The study showed that concentrate supplementation at 2% body weight resulted in greater body weight gain, crude protein intake and apparent crude protein digestibility. Additionally, the weight gain achieved at all grade levels of alfalfa plus in combination with the same amount of urea molasses block was commendable. But, considering the accessibility and cost of conventional concentrate mixture, 2% of Live Weight Alfalfa hay with 100g/head/day urea molasses block is recommended as an alternative supplement regime for better sheep performance.

Due to the increase in food-borne diseases, especially in recent years, consumers' orientation to healthy products and their emphasis on consumption force producers to environmentally friendly products. Nitrogen is the most widely used plant nutrient in the world. Nitrogen, a very expensive input due to its excessive use, pollutes the environment and causes nitrate accumulation in plants. Therefore, vegetable growers strive to replace chemical fertilizers such as nitrogen with environmentally friendly and cost-effective sources. PGPRs stand out in this regard and at the same time, their potential in environmentally and consumer-friendly vegetable production needs to be revealed. In this study, the importance and potential role of N2-fixing PGPR are discussed for the improvement of yield and yield components in environment-friendly vegetable production for healthy human nutrition.

Hakan Saçtı | İlkay Dellal
Technological developments have accelerated the use of information and communication technologies in the agricultural sector as in all other sectors. However, there is still a lack of information in the literature on measuring the level of digital technology usage by farmers. This study will help to eliminate the lack of information on the indicators and their weights that can be used to determine the level of digitalisation of farmers. The aim of the study is to determine the indicators to be used in measuring the level of digital technology use, the sub-dimensions of these indicators, and the weights of these indicators. The constant-sum scale and expert opinions were used to determine the indicators and their weights to be used in measuring the level of digitalisation. The level of agreement of the opinions expressed by different experts about different digitalisation level indicators and their weights was revealed with the help of Kendall’s Coefficient of Concordance. The study results showed that the indicators of internet access facilities, internet speed, smartphone ownership, mobile internet usage, and the ability to use office programs are important variables in measuring the level of digitalisation. The study determined eight main indicators to measure the level of digitalisation and 96 indicators under them, and their weights were put forward. By using the digitalisation indicators and their weights, it will be possible to measure the level of digitalisation in agricultural enterprises reliably.

Orhun Soydan
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.

Agroforestry is a conventional method of land use that could help to address agricultural environmental issues. In order to take advantage of the ensuing ecological and economic interactions, agroforestry is the technique of consciously integrating woody vegetation (trees or shrubs) with crop and/or animal systems. According to recent studies, the global agri-food industry may reach more sustainable methods of producing food and fiber by adopting agroforestry techniques and principles more widely. This would benefit farmers economically and would benefit society as a whole in terms of the environment. Agroforestry promotes eco-intensification based on resource efficiency and offers a wide range of provisioning, regulating, cultural, supporting ecosystem services, and environmental advantages. In this review, we discussed agroforestry with its advantages and developments.

Hatice Çınar
This study aims to define the concept of office spaces and their requirements, as well as the contemporary interior design approaches. It will also cover the interior design and application process for an architecture office in Konya. The company, originally named Çınar Architecture and active in Konya between 1985 and 1990, has been operating as Kerimler Planning Construction Consultancy Company in Konya since 1995. The company requested an interior architecture project for their new location. In the current environment, the office is starting to become outdated and is unable to offer users enough physical amenities. The main goal of the new office’s interior design was to create areas where employers and employees could collaborate in a welcoming and adaptable setting without facing any kind of discrimination. In Konya Meram Pirebi District, the Menekşe Apartment’s ground floor, which is currently a street-level store, is the site of the project, which occupies a total of 280 m2 and consists of a ground + basement. The office occupies 145 square meters on the ground floor of a recently constructed building, with glass extending to the open floor on the south, north, and west facades. The room has a very large opening because the columns are concealed by the walls, making the two stories easily visible from the entrance. The office, which occupies a 135 m2 basement floor, is connected to the elevator and staircase at the back. Natural light enters the basement through the gallery area that is attached to the staircase. Within the parameters of the study, two- and three-dimensional architectural design tools, including phases of the interior design process, were employed in conjunction with a qualitative research method based on inspection and observation. The architectural office put it into practice about half a year after the design stage. The outcome was the creation of a dynamic, modern office analysis that values teamwork and permits the emergence of unique and creative ideas throughout the project.
