Nutrient concentration of forage sorghum (Sorghum bicolor L) varieties under influenced of salinity and irrigation frequency.

The responses of forage sorghum [Sorghum bicolor (L.)Moench] varieties to salinity and irrigation frequency were studied from December 2008 to December 2009 at Universiti Putra Malaysia. Two salt tolerant varieties of forage sorghum, namely Speedfeed and KFS4, were grown under salinity levels of 0,...
