Book Description
Annual potassium (K) fertilization strategies should be based on time of harvest along with the initial nutritional status of the soil to sustain optimum alfalfa (Medicago sativa L.) production. Field and greenhouse studies were conducted to evaluate (a) K and harvest time effect on growth, yield, and nutritive value of alfalfa and (b) effect of K and harvest time on K uptake by alfalfa. Different K rates [0, 56, 112 and 168 (field study); 0, 56, 112, 168 and 224 kg K2O ha−1(greenhouse study)] were applied to alfalfa cultivars [“Hi-Gest 360”; “AFX 457”(field study); Hi-Gest 360 (greenhouse study)] and they were clipped at two harvest times (early harvest, late bud to early [10%] bloom; late harvest, 7 to 10 days after early harvest) under a randomized complete block design with factorial arrangement. Results from the field study showed that total annual forage accumulation was highest at 168 kg K2O ha−1 in early harvest and at 112 kg K2O ha−1 in late harvest. The 2-year average forage accumulation was higher [7.1 Mg dry matter (DM) ha-1] at 168 kg K2O ha−1 in early harvest than at 112 kg K2O ha−1 in late harvest (6.9 Mg DM ha-1). Similar results were also observed for K uptake by alfalfa indicating that K uptake has a direct relationship with alfalfa forage yield. Nutritive value was not affected (P > 0.05) by K throughout the study period probably due to the high initial soil test K levels. However, nutritive value became variable with more harvests at different harvest times. Overall, nutritional status of the soil, particularly K, was higher at the end of the study. The greenhouse study showed that higher K rate (224 kg K2O ha−1) produced higher forage accumulation (689 mg DM plant−1) and K uptake (26 mg K plant−1). The effect (P 0.05) of K on nutritive value is attributed to the low soil test K levels of the soils used in the greenhouse, which justifies the lack of nutritive value differences observed in the field study. Forage accumulation, nutritive value, and K uptake differed (P
