Effects of nitrogen and phosphorus on growth, development, yield, and oil content of safflower (Carthamus tinctorius L.)
(Botswana University of Agriculture & Natural Resources, 2017-07)Safflower is a multipurpose crop grown for the orange-red dye that is obtained from its petals, medicinal properties, feed value and especially for its high quality oil (Dajue and Mondel. 1996; Dwivedi, 2005; Sirel and ... -
Effects of nutritionally-mediated increases in the plasma ammonia concentrations of donor ewes on the in vivo and subsequent in vitro development and metabolism of their embryos
(University of Aberdeen, 1994)A review of the literature indicated that high levels of protein in ruminant diets can lower fertility. Ammonia from proteins that are rapidly degraded by the rumen microbes has been suggested as the factor that may affect ... -
