Equations to describe gas production profiles, obtained using manual or automated systems for in vitro fermentation of ruminant feeds, were derived from first principles by considering a simple three-pool scheme. The pools represented were the potentially degradable and undegradable feed fractions, and accumulated gases. The equations derived and investigated mathematically were the generalized...

The Weibull function is applied extensively in the life sciences and engineering but underused agriculture. was consequently adapted to include parameters metrics that increase its utility for characterizing agricultural processes. included initial final dependent variables (Y 0 Y F, respectively), independent variable (x ), a scale constant (k), shape (c). primary mode, integral average, domai...

Mitscherlich’s function is a well-known three-parameter non-linear regression that quantifies the relation between stimulus or time variable and response. It has many applications, in particular field of measurement reliability. Optimal designs for estimation this have been constructed only normally distributed responses with homoscedastic variances. In paper we generalize literature to D-optim...

Bu çalışma, kuru ve sulu koşullarda toprakta bulunan KCl ile ekstrakte edilebilir NO3-N’u miktarına bağlı olarak artan dozlarda azot uygulamalarının Mitscherlich-Bray Eşitliği kullanılarak ekmeklik buğdayın ihtiyacının belirlenmesi amaçlanmıştır. Tesadüf blokları deneme desenine göre yürütülen denemelerde dekara 0, 3, 6, 9 12 kg N uygulanırken 4, 8, 12, 16, 20 24 olacak şekilde üre (%46 N) gübr...
