Other claims from this paper (16)
- Intervention effect Potassin (P) mixed with N+P+K at 800 ppm decreased Erysiphe cichoracearum conidia germination and germ tube length in vitro.
- Intervention effect Potassium sulphate at 800 ppm decreased Erysiphe cichoracearum conidia germination and germ tube length in vitro.
- Intervention effect Urea (N) was the least effective treatment in the in vitro germination test.
- Intervention effect All tested macroelements as foliar spray reduced squash powdery mildew disease severity under field conditions.
- Intervention effect Foliar (N + P + K) reduced squash powdery mildew disease severity to 18.14% compared with control 63.65%.
- Intervention effect Foliar potassin-F reduced squash powdery mildew disease severity to 18.95% compared with control 63.65%.
- Intervention effect Foliar potassium sulphate reduced squash powdery mildew disease severity to 19.78% compared with control 63.65%.
- Intervention effect Foliar calcium superphosphate reduced squash powdery mildew disease severity to 20.96% compared with control 63.65%.
- Intervention effect Topase and sulpher micronized fungicide gave the best squash powdery mildew disease control.
- Intervention effect Foliar application with all treatments significantly increased squash number of leaves and plant height compared with control.
- Intervention effect Foliar application with all treatments significantly increased squash fresh and dry weight compared with control.
- Intervention effect Spraying squash with Topase gave the highest number of fruits per plant.
- Intervention effect Foliar spray with salpher micronized gave the highest squash fresh and dry weight of plants.
- Intervention effect Foliar application with Urea, calcium superphosphate, potassium sulphate and potassin-N was obtained with the highest average fruit weight, early yield and total yield of squash.
- Intervention effect Different treatments significantly increased leaf N, P and K of squash compared with control.
- Recommendation Foliar application with Urea, calcium superphosphate, potassium sulphate and potassin-N is recommended to raise squash production under the investigated environment.
