Soybean Productivity as Affected by Raised Seedbeds Under Dry Environments

Soybean Productivity as Affected by Raised Seedbeds Under Dry Environments

Aims / Method: The objectives of this research were to evaluate soybean [Glycine max (L.) Merr.] response to early season iron deficiency chlorosis (IDC), agronomic characteristics, and productivity when grown on raised seedbeds compared with flat seedbeds. Soybean grain yield on raised seedbeds, averaged across six drier environments in 2012, was similar to flat seedbeds. Although grain yield ...

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Growth and grain yield of chickpea (Cicer arietinum) cultivars as affected by plant densities under the fall dry land farming

A field experiment was carried out during the 2013-2014 growing season in Lorestan Province (Iran) to evaluate the effect of three planting densities (30, 55, and 83 plant.m-2) on growth indices and grain yield of four chickpea cultivars (Azad, Hashem, Arman and ILC482) under the fall dry land farming condition. The experiment design was factorial based on a randomized complete block design (RC...

Development of Heterodera glycines pathotypes as affected by soybean cultivars.

The reproductive abilities of four races of Heterodera glycines were compared on soybean cultivars by using single cyst or mass inoculations. Progeny transfers were used to determine changes in reproduction of H. glycines. Reproduction of all races (1, 2, 3, 4) was best on 'Lee' and poorest on P1 88788. The size of females produced and numbers of eggs/female of the different races varied with t...

Root Growth and Dry Matter Distribution of Soybean as Affected by Phosphorus Stress, Nodulation, and Nitrogen Source

gy reducing nitrate when NO3-N is the source of available N. Thus, for legumes able to form symbiotic associations with Rh izobium, the pattern of dry matter distribution (DMD) within the plant will differ depending upon its mode of N nutrition. The partitioning of dry matter between root and shoot is a heritable characteristic determined by the genotype of the plant (Andrews, 1939; Shank, 1943...
