Castor (Ricinus communis L.) is a vital industrial oilseed crop with an indeterminate growth habit, often leading to excessive branching that reduces seed quality and yield. This chapter highlights the agronomic practice of nipping—removal of internodal buds on primary, secondary, and tertiary branches—to optimize spike development and improve yield. Nipping enhances air circulation, reduces disease incidence (e.g., botrytis), and improves the source–sink relationship for better photosynthate allocation. When combined with proper nutrition and spacing, nipping significantly increases oil yield and supports healthier crop stands. This practice is especially relevant for dryland farming systems aiming to boost productivity and farmer income sustainably.
