Study of bush feeding role with complete fertilizer and date of sowing in increasing broccoli yield in Mazandaran province climate
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 1
Abstract
Cultivation of broccoli is increasing rapidly in recent years, but the rate of farmer’s knowledge about the technical principles of this plant is relatively low, so current experiment conducted in a factorial split-plot design based on a completely randomized blocks with replications including treatments in horticultural research station of Mazandaran’s agricultural and natural resources research center, located in Qaemshahr city. Studied factors containing; the date of sowing in three times ( rd of September, October and rd of October).In addition a complete fertilizer solution was sprayed in three levels (once every week, once every two weeks and once every four weeks) as soon as transplantings were established. Results showed that the interaction of planting date and fertilizer was not significant in most physiological indexes. However some morphological parameters became significant in measured parameters like stem length, dry and wet weight of root and yield. Yield property showed that there has been nearly difference between maximum and minimum yield of treatments. Maximum achieved yield ( gr/bush) was related to first planting date with once spray of fertilizer in every two weeks. Finally, it could be said that the first planting date and second fertilizer treatment (once every two weeks) allocated the highest wet weight of head part (yield)among existing treatments. Maximum growth parameters were observed in the first planting date and no remarkable difference were seen among various levels of fertilizer treatments.
