The Effect Of Water And Nitrogen On The Response Of Sorghum Cultivars With Contrasting Nitrogen Use Efficiency, Teshome Regassa Apr 2004

The Effect Of Water And Nitrogen On The Response Of Sorghum Cultivars With Contrasting Nitrogen Use Efficiency, Teshome Regassa

Teshome H. Regassa

Water and nitrogen (N) are important environmental factors limiting sorghum production. Information is lacking on the combined effects of water and N for cultivars with different degrees of water and/or N stress tolerance. Sorghum cultivars known for N and water stress tolerance difference were evaluated to identify plant characteristics contributing to N use efficiency (NUE). Cultivars San Chi San and CK-60 were evaluated at Mead, NE on a Sharpsburg silty clay loam soil under water (stress and non-stress), and N (0, 40, 80, and 120 kg ha−1) rates. Experimental units were arranged in split-split plot and treatments were …

Growth Performance Of Datura Innoxia Mill. Under The Stress Of Coal-Smoke Pollution, Azamal Husen, Muhammad Iqbal Jan 2004

Growth Performance Of Datura Innoxia Mill. Under The Stress Of Coal-Smoke Pollution, Azamal Husen, Muhammad Iqbal

Dr. Azamal Husen

One-year-old plants of Datura innoxia growing in natural condition in the Hamdard University campus, New Delhi (normal site) and around the Badarpur thermal power plant, New Delhi (polluted site), were studied and compared for their vegetative growth and pollen viability. The power plant emits 1450 tonnes fly ash and 100 tonnes sulphur dioxide per day. Significant variation was found in plant growth, biomass and pollen viability of the two population. The shoot growth was reduced at the polluted site but the root length, the number of branches and the plant biomass were increased, compared to the control. Pollen viability declined …
