Irrigation scheduling is important for efficient use of applied water and for maximizing crop yields. Therefore, the aim of this study was to evaluate the short-term effect of drip irrigation frequency on soil hydro-physical properties of an Alfisol and performance of two maize varieties, at the Teaching and Research Farm, Faculty of Agricultural Sciences, Ekiti State University, Ado Ekiti, Southwest Nigeria. The experiment was laid out using a split-plot experiment in randomized complete block design (RCBD) and three replications. Irrigation frequency constituted the main plot namely: irrigation four times a week (I4), irrigation thrice a week (I3), and irrigation twice a week (I2) of re-filling soil to field capacity while the subplot was maize variety namely: V1: SAMMAZ-27 and V2: OBA-super-6. Plant growth parameters and soil physical properties of soil water content (SWC), bulk density (BD) and saturated hydraulic conductivity (Ksat) were monitored during the growing cycle. Water use efficiency (WUE) and yield components were determined at maturity. There were significant interactions between irrigation regime and maize variety on SWC and Ksat. The maximum bulk density (BDmax) and optimum soil water content SWCopt were 1.41 g/cm3 and 0.12 g/g, respectively. Plant height (PH) did not differ between the two maize varieties throughout the growth cycle. Drip irrigation frequency did not significantly affect plant height until growth stage V12 (12 fully opened leaves), with I4 irrigation treatment having the tallest plant. Both drip irrigation and maize variety had no significant influence on both LAI and CC, neither was there any significant interaction effect. Increasing irrigation water increased maize yield and yield components. The treatment combination of I4V1 had the highest performance indices in terms of yield components. WUE decreased with increasing frequency of irrigation water application while the WUE of SAMMAZ-27 > OBA-super-6. Therefore, irrigating four times a week and SAMAZ-27 maize variety could be a suitable irrigation-variety combination for providing sustainable irrigation agriculture for maize in this region.

The aim of this research was to determine the structural characteristics of the grapevine sapling producing enterprises and to reveal the problems. The main material of study are data were obtained from questionnaire study. In the study, face-to-face interviews were conducted with 12 enterprises which are members of Sapling Producers Sub-Union (SPSU). During the research period, there were 33 SPSU members, but the majority of these enterprises were small-sized and engaged in the purchase and sale without production. In the research, it was tried to be interviewed with all of the large capacity, both production and sales, and 12 of 33 enterprises were interviewed. The interviewed enterprises hold a large part of the grapevine sapling market. The obtained data were evaluated and interpreted by means of percentage distribution tables, average, maximum and minimum calculations. According to the results of the research, enterprises have been producing grapevine saplings on average at the commercial level for 12 years. All of the interviewed enterprises produce bare-rooted saplings. In addition, potted (58.33%) and American grapevine (25%) saplings also are produced. Grafted sapling yield rates of enterprises have been determined as 45% in own root saplings and 72% in potted sapling. 67% of the producers reported that they have problems in sapling marketing and carrying and storing saplings is a significant problem at this stage. The producers demanded that measures to prevent the informal production from authorities.

Turkey has a great ornithological importance, due to its geographical location, topography, wide territory and different climatic types. From a biodiversity perspective, wetlands are one of the most important areas. Lake Seyfe is one of the important wetlands with economic and ecological value. After being declared a Natural Protected Area in 1989, Lake Seyfe, which gained the status of Natural Protection Area in 1990 and finally declared Ramsar Site in 1994, is extremely important for birds. The lake meets 3 out of 9 Criteria for Identifying Wetlands of International Importance. The research aims to determine bird species of Lake Seyfe by gathering the information contained in the literature covering all observations made in the following years, in addition to the regular field studies conducted weekly between 1996 and 1998. Therefore, a list of birds obtained from all observations made between 1996-2019 has been created. As a result, 26 orders, 57 families, 242 species and 4 subspecies were identified in the site. 20 of the recorded species are globally endangered according to the IUCN red list criteria. Lake Seyfe, an internationally important wetland, is also an important feeding and visiting place for birds during migration.

Accelerating agricultural growth remains one of the most urgent goal of Ethiopia as the agricultural sector is the backbone of the Ethiopian economy. The adoption of new agricultural technologies and improved practices are particularly important in increasing agricultural production. This comprises strengthening legumes adoption and production as it contributes to better food security and more sustainable farming systems. Grain legumes are necessary elements of crop production in Ethiopia. The adoption and use of legume crops have been advocated for enhanced nutrition and preserving soil resources. Different improved varieties and legume production technologies have been made available to farmers through various sectors and projects in the country. Various policy measures and initiatives have also been made in improving the adoption, technology generation and contribution of legumes to the various system. Despite their contribution and considerable initiatives, over-all level of adoption and use of legume production is still low. A wide array of technical, economic, social, and institutional factors has been found to encounter the adoption, use and production of legumes along with their value-chain. However, there are still various opportunities that different grain legumes are to be adopted and promoted to increase production and productivity. Essential interventions, innovative approaches, increased production packages and improved technologies and market access should be emphasized and integrated to strengthen grain legumes adoption and production.

The effects of temperature and pressure processing on myrosinase extracted from fresh broccoli and brown mustard seed was studied. Brown mustard seeds had higher myrosinase activity (2.75 un/mL) than fresh broccoli (0.58 un/mL). The extent of enzyme inactivation increased with pressure (200-800 MPa) and temperature (30-80°C) for both brown mustard seeds and fresh broccoli myrosinase. However, at combinations of lower pressures (200-400 MPa) and temperatures (30-80°C), there was less myrosinase inactivation. When processing at a pressure of 300 MPa with a temperature of 70°C for 10 minutes, there was 65% myrosinase activity for brown mustard while at 300 MPa and 60°C, activity retention in fresh broccoli was 30%. Whereas, the corresponding activity retentions when applying only heat (70°C for 10 minutes) was 35% for brown mustard myrosinase, while there was no measurable myrosinase activity for fresh broccoli (60°C, 10 minutes). Thus, application of moderate pressures (200-400 MPa) on brown mustard and fresh broccoli can potentially be used to retain myrosinase activity needed for subsequent glucosinolate hydrolysis.

Drying method is preferred in agricultural products since it provides advantages in many processes such as increasing the strength of products, transporting and storing. It is necessary to estimate the drying behavior of the products in order to achieve the best drying without reducing the product quality. For this reason, many numerical drying models have been developed to estimate the drying kinetics of the products. Recently, artificial neural networks have been widely used for the development of these models. Artificial neural networks are mathematical models that work in a similar way to natural neuron cells. Radial based artificial neural networks are radial based activation functions in the transition to the hidden layer unlike other networks. In this study, modeling of drying kinetics with radial based networks was investigated. For the experiment, red hot pepper (Capsicum annuum L.) was dipped in boiled water and microwave pretreatments and, then dried in the oven at 65°C. The absorbable moisture values were calculated during the drying period. The radial based artificial neural network models were trained with the drying time values as input and the absorbable moisture values as output. The study was carried out with two data sets including all data and only the average. In trainings with all data, R value of the best model was calculated as 0.9566. R was calculated as 0.9998 with average data.

Progesterone plays a key role in the establishment and maintenance of pregnancy in mammalian. Increasing levels of circulating progesterone in the post-conception period are associated with conceptus elongation and high pregnancy rates in cattle. Contradictory results are available on the direct role of progesterone in early embryo development. The objective of this study was to evaluate direct effects of progesterone on in vitro development of cattle embryos. Immature oocytes collected from slaughtered animals and cultured in the presence of different concentrations of progesterone (25, 50, 100 ng/mL) following in vitro fertilization. Cleavage rates in 25 and 50 ng/mL concentrations of progesterone were significantly higher than those in controls and 100 ng/mL. Rate of embryos that reached to the morula stage was similar in all groups. Supplementation of 25 and 50 ng/mL progesterone to the culture media significantly increased blastocyst yield while 100 ng/mL progesterone resulted in a decrease. As a conclusion, we can suggest that progesterone supplementation in in vitro culture may support embryo development at low levels.

This study aims to compare UV-C irradiation and conventional heat treatment to produce pasteurized onion juice used as a meat marinating agent. The process conditions maximizing the inactivation of target microorganism Escherichia coli K-12 were; 0.5 mm sample depth, 30 min irradiation, 7.5 mW/cm2 UV incident intensity for UV-C and, 74.5°C and 12 min for heat treatment. Except pH and non-enzymatic browning index, differences between physicochemical properties of raw, UV-C and heat-treated onion juices were significant. Springiness and chewiness of unmarinated beefsteaks were higher compared to the ones marinated with the fresh and pasteurized onion juice (UV-C and heat). Pasteurization of onion juice (UV-C and heat) did not significantly affect general liking scores compared to beefsteaks marinated in untreated onion juice.

While the use of pesticides in plant production has positive effects on yield and quality, it has negative effects on human and environmental health. The environment is polluted by the intense and unconscious use of chemicals in agriculture, and the absence of environmentally friendly agricultural methods. This causes problems in the long term, such as reduced biodiversity and disruption of natural balance. This study is important because there are many problems such as the producers' failure to effectively apply methods of combating diseases, pests, and weeds in agricultural production, the use of unnecessary and wrong doses of pesticides, and the methods other than chemical control are not preferred. The aim of this study was to examine the attitudes and behaviors of farmers towards use of pesticides in Çarşamba District of Samsun Province. For this purpose, a survey was conducted with 112 farmers determined by stratified sampling method. According to the findings, most of the farmers in the region do not prefer other methods different form chemical control methods. While farmers found the effectiveness of pesticides at a medium level, they found the price levels of pesticides high. While there is a perception that over-using pesticides adversely affects the environment, biological control methods are not known enough. Various research, education, and extension studies should be carried out for farmers to use pesticides more consciously, and to apply methods other than chemical control.
