Grafted eggplant yield, quality and growth in infested soil with Verticillium dahliae and Meloidogyne incognita

WOS: 000276086700017The objective of this work was to evaluate the effect of grafting (onto Solanum torvum Sw.) on plant growth, yield and fruit quality of the Pala and Faselis eggplant (Solanum melongena L.) cultivars, grown in a soil infested with Verticillium dahliae Kleb. and Meloidogyne incognita, or in noninfested soil. Soil infestation decreased yield, plant height, final above-ground biomass, and also reduced fruit mean weight and shoot dry weight depending on cultivar or grafting. Grafting decreased fruit oxalic acid and the soluble solid contents, and increased mean fruit weight, depending on cultivar and soil infestation. Grafting also reduced the negative effects of the pathogens on disease index, plant height and shoot dry weight. Cultivar Pala was more vigorous than Faselis, and S. torvum was a vigorous rootstock. The combination of a vigorous rootstock with a weak cultivar (Faselis) is more profitable than that of a vigorous rootstock and a vigorous cultivar (Pala). Using S. torvum as a rootstock for cultivar Faselis, grown in soil infested with the pathogens, is most likely to be useful in conventional and low-input sustainable horticulture, since grafting increases protection against the pathogens, and reduces the losses in quality and yield

Post-coronavirus disease 2019 opinions of landscape architects about urban open-green areas

The purpose of this study was to find out if the coronavirus disease 2019 pandemic influenced landscape architects, who have key responsibilities in the planning, design, implementation, and sustainability of public open and green spaces, to reconsider their practice in urban open and green areas. The research was conducted with the landscape architects who have membership in the Union of Chambers of Turkish Engineers and Architects and Chamber of Landscape Architects. The main materials of this study are the participants (individuals with the title of landscape architect), questionnaire forms to ascertain the participants’opinions on the use of open-green spaces following the pandemic, prior scientific research on the topic, and software such as IBM Statistical Package for Social Science Statistics, IBM Statistical Package for Social Science Amos, and Excel used to digitize the research data. The results reflect the landscape architects’ emphasis that open and green space utilization is essential to assisting public health in the fight against pandemics. Additionally, the significance of managing user density inside urban open-green areas, controlling access points into them, utilizing disease-resistant materials in urban furniture, connecting urban green spaces to nearby natural areas, and creating different areas for different age groups was emphasized. Understanding the socio-spatial consequences of the measures taken to prevent the spread of the pandemic and identifying the concepts related to emerging new lifestyles that combine work and life patterns are among the benefits to be obtained from the study. © 2024 Istanbul University-CerrahpaÅŸa.

Parsley production status of Hatay province

This questionnaire study was conducted to determine parsley production status in Antakya, Iskenderun and Samandag districts which had 97.2% of parsley production of Hatay province in 2007-2008 years. Most of parsley production areas in these districts were determined small (0-10 da). While parsley production in Samandag was decreasing, it was increasing in Antakya and Iskenderun districts. Seeds of parsley (Ispanyol) were produced by parsley growers. Seeds were scattered by farmers' hand and fertilizers were applied using base fertilizers which had the ratio (%) of N:P:K 18:46:0 or 15:15:15 in addition to manure. Side fertilizers, Ammonium Sulphate (AS), Ammonium Nitrate (AN), Urea and Calcium Ammonium Nitrate (CAN), were applied generally 25-35 days before harvest and 2-4 times in total. Flow (basin) irrigation method was used and well water as a water source. Weeds were controlled by herbicides+hands. Pests and diseases were controlled by pesticides. Farmers in the districts, except Samandag, were aware of harvest time after chemical usage. While advises about chemicals and fertilizers were taken from chemical sellers in Antakya and Iskenderun, farmers in Samandag were using their own experiences. Parsley was harvested 1-2 times in Antakya and Iskenderun, whereas in Samandag more than twice. Harvest and bunch numbers were affected from status of climate, soil, plant, market, prices and merchant. All yields were bought wholesalely and cheaply by merchants. It was concluded that if the parsley producers were educated and supported on modern parsley production and marketing, yield and quality of parsley could be increased

Leaf mineral composition of grafted eggplant grown in soil infested with Verticillium and root-knot nematodes

WOS: 000282876200014The objective of this work was to determine differences in leaf mineral composition between ungrafted and grafted onto (Solanum torvum) eggplant (Solanum melongena), cultivars 'Faselis' and 'Pala', grown in a soil infested with Verticillium dahliae and Meloidogyne incognita, or in a noninfested soil. Grafting increased leaf P and Mn concentrations, and decreased N concentrations, in both soils. Grafting also enhanced leaf Ca concentration of 'Pala', but it did not affect that of 'Faselis' depending on the cropping year. Leaf Mg concentration of grafted plants in infested soil was lower than that of ungrafted ones in noninfested soil. Results showed that, under the same fertilization program, the grafted 'Faselis' plants used the nutrients more efficiently than the 'Pala' ones. Use of S. torvum as a rootstock for 'Faselis' resulted in an effective protection against multiple pathogen infestation. Fertilization may be necessary when grafted 'Faselis' plants are grown in a soil infested with the pathogens, since grafting and infestation generally decrease leaf N, Mg, Ca and Fe concentrations, either by reducing the nutrient concentrations directly or by increasing leaf Mn concentration.Mustafa Kemal UniversityMustafa Kemal UniversityTo Mustafa Kemal University, for funding the project; and to Dr. Mehmet Arslan, for reviewing the earlier version of the manuscript
