TLDR
It is demonstrated that seed yield of some bush-type cowpea cultivars can be substantially increased in intensive commercial production by increasing plant density from the currently used densities of 100–133 tph to 400 tph.About:

TL;DR: In this paper, the authors reviewed accomplishments in cowpea cultivar and germplasm development by the bean/cowpea Collaborative Research Support Program (CRSP) which was funded by the United States Agency for International Development for a period of about 20 years.

Growth and yield characteristics of Lesquerella fendleri as a function of plant density
TL;DR: Plant densities of 750 000 and 1’000 Thousands plants/ha are recommended for lesquerella growing areas comparable to central Arizona, and maximum plant heights were obtained at these densities, minimizing seed loses during combine harvest.

Comparative Ecophysiology of Cowpea, Common Bean, and Peanut
TL;DR: This work concentrates on biotic stresses that interact with resistance to abiotic stresses and factors influencing yield potential, and Symbiotic associations involving rhizobia and mycorrhizal fungi are particularly relevant to the function of grain legumes in cropping systems.

Relationship between stress tolerance and grain yield stability in cowpea
TL;DR: Assessment of cowpea genotypes in the Guinea and Sudan savannah zones of Ghana found that simultaneous selection for grain yield and tolerance to stress in the less favourable environments will identify genotypes broadly adapted to the majorcowpea growing regions.

Varying plant density and harvest time to optimize cowpea leaf yield and nutrient content.
TL;DR: Cowpeas were grown in a greenhouse for leaf-only harvest at 14, 28, 42, 56, 84, or 99 plants/m2 and harvested 20, 30, 40, or 50 days after planting (DAP).

The breeding of crop ideotypes
TL;DR: It is postulated that a successful crop ideotype will be a weak competitor, relative to its mass, and the like plants in the crop community will compete with each other to a minimum degree.

The Biological Yield and Harvest Index of Cereals as Agronomic and Plant Breeding Criteria
C.M. Donald,John Hamblin +1 more
TL;DR: The chapter examines the interaction of biological yield, grain yield, and harvest index with plant density and the situation in which a number of varieties have precisely the same biological yield but different grain yields is graphically presented.

Light-mediated bioregulation of tillering and photosynthate partitioning in wheat
M. J. Kasperbauer,D. L. Karlen +1 more
TL;DR: The light spectral shifts associated with field plant population densities and the responses to red and far-red treatments under controlled environments suggest that phytochrome serves as a sensing mechanism that detects the amount of competition from other plants, and regulates the development of tillers and the partitioning of photosynthate between shoots and roots.
