Multivariate factor analysis and principal component analysis were used to decompose the correlation matrix of test-day milk yields of 48,374 lactations of 21,721 Italian Simmental cows. Two common latent factors related to level of production in early lactation and lactation persistency, and 2 principal components associated with the whole lactation yield and persistency were obtained. Factor ...

a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...

The effects of four sulphur levels: S0, S1, S2 and S3, including 0, 12, 24 36 kg S ha-1, respectively, along with 115 N ha-1 were studied on yield-related traits oilseed rape (Brassica napus L.). significant variance treatments was determined for plant height, yield component characters, seed oil content. application significantly increased most the compared to S0 level. S3 (36 ha-1) treatment ...

A model is created for the number of integrated circuits that are good from each wafer on which they are fabricated. The goal is to separate the random or common cause loss from the systematic or special loss. The random loss from this type of process is modeled so that false alarms indicating systematic loss are less likely to occur and so that the structure of the systematic loss can be deter...
