This study aims to quantify the phosphorus (P) concentration in the commercially adapted ten corn hybrids in South Dakota and to determine if selection can be carried out for these traits to develop useful inbred lines; to determine the effect of planting densities on P concentrations and dry matter (DM) yields. Results showed that hybrid were significantly differences for percent phosphorus. H...

The objective of this study was to investigate the effect of a partial substitution of soybean meal with field pea (Pisum sativum) in Holstein lactating dairy cow diets on dry matter intake, milk yield and composition, blood metabolites, rumen ammonia-N concentration and pH. Eighteen lactating Holstein cows were randomly assigned into three groups based on parity, days in milk, and mil...

In order to evaluate grain yield potential and study dry matter remobilization to seed, 8 commercial bread wheat cultivars were examined in two separate experiments, using randomized complete block design with 4 replications in 2003. There were significant differences for most traits in normal and drought conditions. Sarday variety had the least grain yield in the two environments. There was c...
