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.

`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.
