Strawberry responses to K rate on a find sand soil
1991
Albregts, E.E. | Howard, C.M. | Chandler, C.K.
Strawberry (Fragaria X ananassa Duch.) was grown for two seasons on a fine sand soil to study the plant and fruiting response of three cultivars to K rates of 0, 56, 112, 168, and 224 kg-ha-1. 'Dover' total fruit yields increased linearly with rate both seasons while the maximum March yield the first season was with 170 kg K/ha. April yields increased linearly with K rate the first season. 'Tufts' and 'Chandler' responses to K rates were not consistent for monthly or total fruit yield. The average fruit weight of 'Dover' and 'Tufts' decreased linearly with increasing K rate for March and for the season in 1984, while 'Dover' gave a positive linear average fruit weight response to K rate during Apr. 1986. 'Dover' leaf K decreased from December to February, and K deficiency symptoms were expressed by February in treatments receiving lower rates of K. Leaf K concentrations of 'Dover' correlated well with K rate.
