Varying Plant Density and Harvest Time to Optimize Cowpea Leaf Yield and Nutrient Content

Corn yield and yield stability under varying nutrient management, crop rotation, and rainfall

Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...

Early leaf harvest reduces yield but not protein concentration of cowpea seeds.

Five greenhouse-grown cowpea [Vigna unguiculata (L.) Walp] cultivars were tested in a generalized random complete-block design to determine the effect of early leaf harvest on dry weight and protein concentration of plant parts at maturity. The most recent, fully expanded leaves on each branch from one group of plants were harvested at 5 and 7 weeks after planting. On the other groups of plants...

Yield and Yield adjustments of nonprolific maize hybrids in response to plant population density

Effect of leaf orientation and density on yield of corn

effects of plant density and harvest time on root yield and quality of chicory (cichorium intybus l.)

effects of plant density and harvest time on various two ecotype and one variety of chicory was examined at qazvin sugar factory research station in 2012. three genotype of chicory (two ecotypes of zanjan and kashan and one denveloped variety named orchis) with three plant densities (6, 12, and 18 plants/m2) and three harvest dates (31 august and 20 september and 11 october) were considered usi...
