The present disclosure provides a simplified cotton cultivation method relying on setting bolls on VBs. Not only can the method form seed cotton yield and increase the yield by at least 10% compared with conventional manual pruning or no-prune technique, but also eliminate pruning and topping. The method is a new, simple and feasible simplified cotton cultivation method. The simplified cotton cultivation method relying on setting bolls on VBs includes the following steps: heading a cotton plant to retain only VBs when cotton grows to squaring stage, namely cutting off the first fruiting branch and an upper main stem thereof from the cotton plant after squaring, and only retaining the vegetative branches for growth and development, squaring, flowering, and setting bolls.

This invention relates to methods and materials for providing a benefit to a plant by associating the plant with a complex endophyte comprising a host fungus further comprising a component bacterium, including benefits to a plant derived from a seed or other plant element treated with a complex endophyte. For example, this invention provides purified complex endophytes, purified complex endophyte components such as bacteria or fungi, synthetic combinations comprising said complex endophytes and/or components, and methods of making and using the same.

Provided is a method for improving the cotton crop yield. This method for cultivating cotton comprises treating seedlings at least once with a plant activator containing an exogenous elicitor and an endogenous elicitor.

Provided are methods for growing a plant under certain stressed conditions that alter the morphology of the plant. In certain aspects, however, although the plant is altered and may be undesirable for commercial purposed, the plant still produces an adequate number of seeds for breeding purposes. Further, because plants may be smaller in size, they can be grown at higher densities, allowing the production of large populations of plants to be brought under controlled conditions which can exclude pollinating insects and thus increase the genetic purity achievable in a breeding program.
