Abstract
Field experiments were carried out to evaluate the effects of different doses of fertilizer P and Zn on growth and yield of geranium and garlic in a intercropping system. Application of phosphorus at 40 kg P2O5 ha−1 proved significantly better than control (no P) in the production of geranium oil and garlic bulbs. Uptake of Zn also increased significantly up to 40 kg P2O5 ha−1. Higher rates of P decreased the Zn uptake by the plants. Application of 30 kg Zn SO4 ha−1 showed a significant response on the herb and oil yields over the no zinc application. Application of 40 kg P2O5 and 30 kg Zn SO4 ha−1 is, therefore, recommended for achieving the maximum yield advantages in a geranium-garlic intercropping system.
