bitkisinin bazı özellikleri üzerindeki etkisinin araştırılması amaçlanmıştır. Lokasyonların, ekim zamanlarının, lokasyanxekim zamanı interaksiyonlarının börülce çeşidinin çiçeklenme gün sayısı, bitki boyu, bitkide dal sayısı, bitki başına tane ağırlığı ve dekara tane verim değerleri üzerinde önemli etkiye sahip olduğu bulunmuştur. Dal sayısının lokasyon ve ekim zamanları yönünden, ilk bakla yüksekliğinin ekim zamanları, lokasyonxekim zamanı interaksiyonu yönünden farklılık gösterdiği belirlenmiştir. Araştırmada kullanılan börülce çeşidinin lokasyonlara ve ekim zamanlarına göre çiçeklenme süresi 32-72 gün, bitki boyu 28-176 cm, dal sayısı 6-10 adet, ilk bakla yüksekliği 19-33 cm, bitki başına tane ağırlığının 3-24 g ve dekara tane verim 53-412 kg da-1 değerleri arasındaki değiştiği görülmüştür. Börülcenin 5 Haziran ve 20 Haziran ekim zamanları Şanlıurfa ve Kahramanmaraş lokasyonlarında 2. ürün ekim zamanlarına denk gelmektedir. Bu bölgelerde börülcenin 2. ürün olarak ekilebileceği görülmüş, fakat birinci ürün ekiminden daha az verim alınacağı kaydedilmiştir.
In the traditional growth curve or milk yield models used in animal husbandry; models such as Brody, Von Bertalanffy, Logistic, Gompertz and Richards are used based on classical regression analysis. In this study, an alternative growth curve or milk yield model was proposed with the help of sinusoidal functions based on trigonometric functions. In this model, a sinusoidal curve model fitting and parameter estimation have been made by using a numerical sample of milk yield data set. In addition, this study aims to explain the applicability of periodic features of sinusoidal functions in agriculture and animal data. It is thought that this solution which can be applied in different fields will be beneficial for researchers.
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.
