Abstract:
... Rock phosphate (RP) is an important natural source of P for plant nutrition, but the solubility and availability of P from RP is an issue in agricultural production systems. Integrated use of RP with various organic and inorganic byproducts has been reported to increase RP P use efficiency and stability of crop yields. A 2-yr (2010–2011 and 2011–2012) field experiment was conducted to examine the ...

Abstract:
... Introgression of favorable alleles from exotic maize (Zea mays L.) germplasm can broaden the narrow genetic base of available temperate germplasm. Development of maize hybrids for the Yellow and Huai river valleys in the Corn Belt of China has always been hampered by the lack of favorable alleles for improving maize yield and quality. Twenty exotic populations from CIMMYT and the United States wer ...
