Spacings between plants with chicken manure in Roselle crop

Composting Unamended Chicken Manure

Normally, manures are composted with amendments. However, a large commercial egg producer in Ohio i s composting unamended chicken manure. Studies were done to characterize this composting, both in situ and in pilot-scale vessels. While overly wet material can hamper initial operation, the general progression dries the material and produces a granular output that is below 20 percent (wet basis)...

Growth, Productivity and Chemical Constituents of Roselle (Hibiscus sabdariffa L.) Plants as Influenced by Cattle Manure and Biofertilizers Treatments

This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of different levels of cattle manure and biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers an...

Biofortification of Crop Plants

Salt resistant crop plants.

Soil salinity is a major constraint to agriculture. To improve salinity tolerance of crops, various traits can be incorporated, including ion exclusion, osmotic tolerance and tissue tolerance. We review the roles of a range of genes involved in salt tolerance traits. Different tissues and cells are adapted for specific and often diverse function, so it is important to express the genes in speci...

Developing heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops

Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...
