Augustine Rajendran | Imayavaramban Veeramani
An experiment was carried out at the ICAR-KVK Research farm, HansRoever Campus, Perambalur, Tamil Nadu, India during the Kharif season (July to October), 2020 to study the effect of agronomic biofortification through integrated nutrient management on hybrid maize (biofortified and non-biofortified). The experiment was laid out in Split Plot Design having 36 treatment combinations of hybrids and nutrients and replicated thrice. The treatment sources consisted of two main plots of maize hybrids (M1: Non-biofortified and M2: biofortified), and six sub-plots of nutrients (S1: 100 % Recommended Dose of Fertilizer RDF through Nitrogen, Phosphorus, Potassium, S2: 100 % RDF through Farm Yard Manure, S3: 50% RDF through NPK + 50% RDF through FYM, S4: S1+ Iron and Zinc as foliar application @0.5% conc, S5: S2 + Iron and Zinc as foliar application @0.5% conc, S6: S3 + Iron and Zinc as foliar application @0.5% conc.). The recommended dose of fertilizer was NPK 150:75:75 kg ha-1. Application of 50% RDF through NPK + 50% RDF through FYM with Fe and Zn as foliar application @0.5% conc (S6) at 45 (active vegetative stage) and 90 (grain filling stage) days after sowing, significantly increased all the growth and yield attributes, grain and stover yield, quality attributes and nutrient uptake by maize. Among the nutrient levels, higher grain yield (8.2 t ha-1) and stover yield (10.16 t ha-1), quality attributes, and nutrient uptake were recorded with the application of 50% RDF through NPK + 50% RDF through FYM with Fe and Zn as foliar application @0.5% conc (S6). Similarly, significant net return (INR 78,767) and benefit cost ratio (3.07) were noted with the application of 100% RDF through NPK (S1) followed by 50% RDF through NPK + 50% RDF through FYM with Fe and Zn as foliar application @0.5% conc (S6). Hence, integrated nutrient management with agronomic biofortification @0.5% conc., at 45th and 90th DAS should be adopted to obtain maximum grain yield, net profit, and nutrient uptake by Kharif maize.

In this study; The effects of using urea as top fertilizer and "Nutrisphere-N-Urea" fertilizer, which is a nitrogen stabilizer, on some yield and quality criteria of bread wheat and corn were investigated. Experiments were carried out in the fields of the Eastern Mediterranean Agricultural Research Institute according to a randomized block design with four replications. In the wheat trial; control (no fertilizer), conventional-DAP (15 kg/da)+Urea (29 kg/da), DAP (15 kg/da)+Nutrisphere-N-Urea (15 kg/da) and DAP (15 kg/da)+Nutrisphere-N-Urea (29 kg/da) subjects including were studied. In the corn trial; 25 kg DAP/da+without top fertilizer; 25 kg DAP/da+60 kg Urea/da and 25 kg DAP/da+60 kg Nutrisphere-N-Urea/da were the subject of the research. As a result of the observations and analysis of variance, the effect of the use of "Nutrisphere-N-Urea" on yield and yield criteria in wheat, despite the classical top fertilizer (Urea) application, was found to be statistically significant. While the yield per decare was 326.88 kg in the traditional application, it was found to be 388.46 kg when Nutrisphere-N-Urea (15 kg/da) was used. In the corn trial; While the effect of the use of "Nutrisphere-N-Urea" on plant height, first ear height and hectoliter weight was found to be statistically insignificant compared to the control subject, it was seen that it caused statistically significant differences on stem diameter and yield values. The highest yield (1774.31 kg/da) and crude protein (8.95%) and low starch ratio (67.73%) were obtained from the “25 kg DAP/da+60 kg Nutrisphere-N-Urea/da” application.

Structures of agricultural holdings have been changing rapidly in rural areas. While smallholders have been decreasing in number, the number of large farms has been increasing. Youth has been rapidly moving away from agriculture. The agricultural sector has faced an aging problem. The involvement of youth and smallholders in agricultural production is extremely important for food supply security. This study aimed to observe the structural change of agricultural holdings based on the Farmer Registration System (FRS) data. The answers to the following questions were sought. Has the numerical and proportional distribution of enterprises changed according to their size? Has youth been moving away from agriculture? FRS records between 2003-2020 were used in the study. Agricultural holdings were grouped according to their size and the age of farmers. Results were summarized in tables and graphics. There was a decrease in the number and rate of farmers under the age of 40, and a proportional increase in the number of farmers over 65. While the number of agricultural holdings larger than 500 increased 2.5 times, the number and rate of small farms decreased. Migration from the districts and villages in the study area has been observed at rates ranging from 22% to 59% in 20 years. Special measures should be taken for youth and small farms to survive in the agricultural sector. Tools such as tax exemption and social security support can be used. Integrated rural development approaches, including basic services such as education and health, are indispensable for the population to be permanent in rural areas.

After the COVID-19 was declared as a pandemic, nothing has ever been the same for humankind. The lockdown, travel restrictions, closure of borders, and restriction of the movement of people and materials through quarantine measures applied all over the world to combat the COVID-19 pandemic affected agriculture alongside many sectors. The pandemic has made countries reconsider the issue of self-sufficiency in agriculture and it has been understood once again that agriculture is an indispensable element of human life. Agriculture is generally an input-intensive industry. Plant protection products, fertilizers, seeds, fuel, and labor are among the most important of these inputs. Failure to occur in one or more of these means a decrease in the quality and quantity of the product. Countries that do not want to face such a problem have taken some measures during the COVID-19 pandemic, some have been successful, and some have been insufficient. The COVID-19 pandemic has led to labor shortages in plant production, difficulties in accessing plant protection products, and disruptions in plant protection practices due to lack of labor force, financial problems and equipment shortages. The pandemic has also affected education and research activities. With this review, we tried to discuss the impacts of the COVID-19 pandemic on plant production and plant protection in Turkey and in the world.

The visual perception of landscapes is expressed as seeing the qualities of the landscape. This level of perception varies depending on the socio-cultural and economic structure of the people and the environment in which they live. The fact that the environment in which people live has a variable visual structure also constantly affects their landscape perception. Parks are one of the important urban landscape areas in cities. The existing structure of the parks located in the urban landscape areas affects the visual perception value of these areas on the users. The aim of the research is to evaluate the visual landscape quality value of the parks in the city of Serik in the direction of user opinions. In this context, the photographs of the selected parks within the boundaries of the research area were taken from certain points. The questionnaire form prepared with these photographs was applied to the park users on a voluntary basis. The data obtained from the questionnaire forms were digitized and analyzed. Within the scope of the analysis, the data belonging to the socio-demographic structure of the participants and the answers they gave to the propositions about the parks were determined by descriptive analysis (frequencies and descriptives). Whether there was a statistically significant difference between the sociodemographic structure of the participants and their answers to the propositions was analyzed with parametric tests (independent sample t-test and one-way analysis of variance). At the same time, the relationship between the visual landscape quality assessment criteria of the parks was examined by Pearson Correlation Analysis. The results of the analysis show that the features of the parks due to their planning, design and maintenance affect the visual landscape quality values. In this direction, suggestions have been developed to increase the visual landscape quality value of the parks.

Purple basil is widely used medicinally and aromatically due to its essential oil properties, and it is a plant that stands out with its antibacterial, antimutagenic and antioxidant properties. It has been determined that purple basil has positive effects on health such as appetizing, insomnia, sputum, diuretical and antispasmodic. Purple basil contains high concentrations of anthocyanins and with these properties it stands out as a potential new source of stable red pigments for the food industry. In recent years, it has been seen that purple basil has been processed into different products such as tea and sherbet in order to benefit from its functional properties. With the processing of purple basil into different products, it is seen that the consumption of basil and basil products has increased by consumers. In this study, purple basil sherbet samples were concentrated at different voltage gradient values (14, 17 and 20 V/cm) under atmospheric conditions with ohmic heating up to 25% soluble solid content (SSC) and the changes in their rheological properties during the concentration process was investigated. The changes in the rheological properties of the purple basil samples were determined in the range of 1-148 s-1 shear rate values and measurement temperature was 25°C. The compatibility of different rheological models (Newton, Power-Law and Herschel-Bulkley) to the experimental data was statistically evaluated to determine the flow behavior index of the purple basil sherbet samples. It has been determined that the shear stress values increased as the shear rate values increased in all the process conditions. Similarly, at the same shear rate values, it was determined that the shear stress values increased as the SSC values increased. It has been determined that the best suitable rheological model was Herschel-Bulkley Model for all purple basil sherbet concentrates. It is thought that the results obtained will provide important data to the food and machinery industry for the installation of pilot and industrial scale ohmic heating systems.
