Altuner et al.: The impact of different sowing-times of the quinoa (Chenopodium quinoa Willd.) and its varieties on the yield and yield components in Turkey-Mardin ecology condition -10105 -

Background: Legumes and cereals microgreens are consumed both in healthy nutrition and as a natural food against many degenerative diseases due to their rich bioactive content. The research was carried out to determine the biochemical contents of 5 legumes and 7 cereals. Methods: The research was conducted in Van Yuzuncu Yıl University Field Crops Department Laboratory in 2020, in a controlled growing environment, according to the completely randomized experimental design. Total antioxidant activity, total phenolic, total flavonoid and total ascorbic acid contents and total Chlorophyll, Chlorophyll a, Chlorophyll b and Carotenoid contents and correlation between them were determined. Result: The differences between the means of all traits were found to be significant. The biochemical contents of cereals were 1.6-7 times higher than legumes. There was no big difference between the pigment values. In legumes, Bilensoy alfalfa had the highest total antioxidat activity and total flavonoid content, Uzbek lentil total phenolic content and Goynuk bean had the highest Total ascorbic acid. In cereals, Kirklar oat had the highest total antioxidat activity, total phenolic, total flavonoid and total ascorbic acid contents, while Larende barley had the lowest values (except total ascorbic acid content). While total Chlorophyll and Chlorophyll a amounts were highest in Kirklar barley and lowest in Uzbek lentils, the opposite situation occurred in Chlorophyll b and Carotenoid amounts. There was no significant correlation between biochemical parameters in legumes. There was a positive and significant correlation between total phenolic content with total antioxidant activity and between total ascorbic acid with total fenolic content in cereals. There were positive and significant correlations between all pigment parameters in both legumes and cereals.

Özet: Van'da hayvancılığın ihtiyacı olan kaba yem çayır-meralardan, sap samandan ve yem bitkileri tarımından sağlanmaktadır. Tarım ve Hayvancılık potansiyeli yüksek olan Van İlinde halkın önemli bir kısmının geçimi bitkisel ve hayvansal üretime dayalıdır. Hayvansal üretimde kaba yem temini büyük önem arz etmektedir. Van ilinin sahip olduğu 1.359.022 ha'lık çayır-mera alanlarından üretilen kaba yem üretim miktarı yaklaşık 67.951 tondur. Yem bitkileri tarımı yapılan 1.045.859 ha alanda üretilen yem bitkileri miktarı ise yaklaşık 899.540 ton civarındadır. Buna karşılık Van ilinde 172.000 Büyük Baş Hayvan Birimi varlığı bulunmaktadır. Bu hayvanların sadece yaşama payı kaba yem ihtiyacı yılda ortalama 619.200 tondur. Ancak kaliteli kaba yem üretimi 967.491 ton düzeyinde kaldığından, kaba yem açığı % 36 civarındadır. Van'da hayvancılığın kaba yem sorununu çözmek için bilimsel, teknik, ekonomik ve sosyal önlemler alınmalıdır. Yem bitkileri üretim alanlarının ve kaliteli kaba yem üretiminin artırılması için devlet desteklerinin devam etmesi ve tohumluk sorunu da çözülmesi gerekir. Tohum üretimi yapan üreticilerin de destek miktarının arttırılması büyük önem arz etmektedir. Ayrıca hayvansal üretimden arzu edilen verimin alınabilmesi için rasyonel besleme ile beraber kaba yem kaynaklarının da doğru kullanılması gerektiği konusunda üreticiler bilgilendirilmelidir.Anahtar Kelimeler: Yem bitkileri, çayır-mera, ekim alanı, kuru ot verimi, hayvan varlığı The Roughage Production Potential, Problems and Suggestions in Van ProvinceAbstract: The solid feed needed for cattle breeding in the province of Van is generally obtained from pastures, meadows and feed grains. The majority of people rely on agricultural and food of animal origin in the so called province which has got a high potential of agriculture and animal breeding. In terms of animal breeding, providing the solid feed is of great importance. The production of solid feed from pastures and meadows stretching into an area of 1.359.022 hectares is almost 67.951 tons. Another area of 1.045.859 hectares where the feed grains are raised has a potential of productions adding up to 899.540 tons. There are predictably 172.000 great cattle in the province of Van. These animals need on average 619.200 tons of feed grains just to be able to survive annually. However high quality solid feed production is almost 967.491 tons, which means that there is approximately 36% percent of deficit as for the demand of the feed grains. There needs to be scientific, technical, economical and social measures taken into consideration in order to solve such demand and consumption problems of feed grains. Governmental support so as to expand the areas for feed grains and enhance the production of high quality feeds should continue and the problem of seed or seedbeds should be solved. It is highly significant that the producers or farmers involved in seed production need to be included into governmental support as well. Moreover the producers or farmers have to be informed of the importance the proper...
