Abstract

The present investigation was carried out to evaluate the effect of vermivash on yield and leaf nutrient status of strawberry "Govieta" at research greenhouse of Shahrekord University in 2013. Treatments were included control (without vermiwash foliar spray) and different concentration of vermiwash (10, 15 and 25 percent) that spryed at 1, 2 and 3 weeks interval. Vermiwash was extracted from cow manure vermicompost through earthworm Eisenia foetida. The experiment was conducted in completely randomized design (CRD) with three replications. The results showed that there was significant difference between vermiwash treatments and control for the leaf elements of N, K and Fe, but was not significant for the other macro and microelements. Leaf Fe concentration increased up to excessive level in 25 percent concentration with weekly interval. Foliar spray of 25, 15 and 10 percent vermiwash with two-weeks intervals considerably enhanced the number of fruit and yield per plant, but decreaced fruit weigth average a little. Increasing the yield per plant ranged between 24 and 68g for various vermiwash treatments in comparison with control. Vermiwash treatments had no effect on inflorescence number per plant and flower number per inflorescence. Foliar spray of 15 and 10 percent vermiwash with two-weeks interval improved the yield of strawberry "Govita".
