In this study, the effects of on 20 April, 5 May, 20 May, 5 June, 20 June, 5 July and 20 July sowing times application in Kahramanmaras and Sanlıurfa conditions on the quality criteria of Simal cowpea variety were researched. The experiment was established in 2015 as a randomized trial design with four replications. The pod length, number of grain of each pod, dry hay weight, moisture ratio, oil ratio, protein ratio and starch ratio characteristics of Simal variety (Vigna sinensis L.) were investigated. At the end of the research, it was noted that the number of grain of each pod, dry hay weight, the moisture ratio, the oil ratio, the protein ratio of cowpea, in terms of the locations, sowing times and locationxsowing time interactions were significantly different. It was determined that the length of pod is insignificant in terms of sowing time, and starch ratio was significantly showed differs in terms of location and location x sowing time interactions. The grain number of each pod, the weight of dry hay, the moisture ratio, the fat ratio, the protein ratio, starch ratio of cowpea were reported varieties from 7 to11.37 unit, from 361 to 1631 kg da, from 10.87 to 13.44%, from 1.28 to 2.11%, from 22.81 to 25.45%, from 42.11 to 49.77% respectively. As a result, it was observed that the characteristics of the cowpea investigated were affected by the environmental conditions.

Organic matter has a positive effect on the uptake of nutrients in the soil. The increase in mycorrhizal activities in the soil causes an increase in the activities in the rhizosphere region. Vermicompost is among the most useful organic fertilizers that can be added to the soil in recent years. Soil microflora is capable of realizing the return of mineral substances. Akkız cowpea variety was used in the study: The experiment was carried out as a viol study with 3 replications according to the randomized blocks trial design. In the study, seedling development was achieved by mixing vermicompost (0, 15, 30 and 45%) with and without mycorrhiza in a soil containing 16% lime into the viols in order to develop seedlings. Sufficient minerals have been applied to the plants for their growth. Seedlings were harvested when they were 40 days old, and seedling measurement parameters and macronutrients in plant leaves were checked. As the amount of vermicompost increased, it caused an increase in the above-ground fresh and dry weights, root fresh and root dry weights of the seedlings. As the organic fertilizer mixture increased, the nitrogen, phosphorus, potassium and magnesium concentrations of the plant leaves increased. The addition of mycorrhiza to the rearing medium has led to different results in the investigated characteristics. Addition of increasing organic fertilizer ratios in the study, Organic fertilizer and bacteria application of cowpea cultivars were effective in increasing the development of plants in calcareous soils.

Bu araştırma, Türkiye’de kuru dane olarak kullanımı için tescil edilen dört börülce çeşidinin bazı morfolojik ve tarımsal özelliklerini belirlenerek amacıyla 2013 ve 2014 yetiştirme sezonunda, Amik ovası koşullarında, tesadüf blokları deneme desenine göre üç tekrarlamalı olarak yürütülmüştür. Araştırma sonuçlarına göre, en yüksek bitki boyu (221,8 cm) ve en yüksek ilk bakla yüksekliği (43,6 cm) Sırma çeşidinden; en yüksek bitkide dal sayısı (4,0 adet), en yüksek bakla uzunluğu (14,9 cm), en fazla bitkide bakla sayısı (19,8 adet), en fazla bitkide tane sayısı (113,5 adet), en fazla yüz tohum ağırlığı (22,2 g) ve en yüksek tane verimi (275,2 kg/da) Amazon çeşidinden; en fazla baklada tane sayısı (6,2 adet) ve en yüksek hasat indeksi (%39) ise Karagöz çeşidinden elde edilmiştir. Ayrıca yapılan korelasyon analizi sonucunda incelenen bazı özellikler arasında istatistiksel olarak hem olumlu hem de olumsuz ilişkiler tespit edilmiştir. Dekardaki tane verimi göz önüne alındığında Amik ovası koşullarında denemede yer alan börülce çeşitleri içerisinde Amazon çeşidinin üreticilere tavsiye edilebileceği ortaya çıkmıştır.
