Global agricultural production has risen substantially in recent decades and needs to rise further to meet the ever-growing food demand. While higher production can be directly attributed to agri...
NSF-funded scientists at Cold Spring Harbor Laboratory are figuring out how to pack more kernels onto a corn cob. One way to boost the productivity of a plant, they say, is to redirect some of its res...
The El Niño-Southern Oscillation, ENSO, has been responsible for recent widespread, simultaneous crop failures, according to a new study by researchers at Columbia University, the International F...
Biologists at Cold Spring Harbor Laboratory (CSHL) have made an important discovery that helps explain how plants regulate the proliferation of their stem cells. The discovery has near-term implicatio...
Whole-crop wheat (Triticum aestivum L.) as forage has been extensively used in the world. In this study, the effects of N application rates on the yields, nutritive value and silage quality were inves...
Intercropping of grain legumes and cereals is a promising theme in organic farming for its potential for increasing and stabilizing yields, reducing weed pressure and sustaining plant health. On anima...
Yield is the characteristic by which a cultivar is commonly judge. A cultivar may be considered satisfactory only if it is able to produce a good yield in comparison to others at various times and in ...
To elicit information on the optimum spacing and N fertilizer rates for rice production under rain fed conditions at Abakaliki Agro-ecological zone, field trials were conducted at Ikwo with rice vari...
Scarcity of water often reduces the regional production of soybean (Glycine max (L.) Merr.) in many areas where it is grown. Contemporary climate change is characterized by increase in frequency and i...
The grain yield and grain protein content of winter triticale in dry farming can be significantly affected by environmental conditions and different nitrogen (N) levels. Two year field trials with six...
Seed and oil yields, their components, and the relationships among yield and related traits were measured in 5 spring safflower (Carthamus tinctorius L.) genotypes, Local Arak, Local Esfahan, Sina, KH...
To clarify lodging resistance of high yield examples, characters related to lodging of Shan You 63 (F1 hybrid rice) with 965 gm-2 of a brown rice weight were analyzed. There were various factors for e...
Analysis of the characteristics of grain production of 965 gm-2 obtained by Shan You 63 (F1 hybrid rice) in 1991 was carried out Absorption of nitrogen reached 21 gm-2 up to the time of heading, and a...
The annual rate of rice yield increase in the world declined from 2.7 % in the 1980s to 1.1 % in the1990s. The continued world population increase requires resumption of the previous rate. The objecti...
Aggregate sheath spot (AgSS), a disease caused by Rhizoctonia oryzae-sativae, is one of the major rice (Oryza sativa L.) diseases in California. A three year study was initiated in 1998 to evaluate t...
