The Effect of Hazelnut Husk Enriched With Organic Fertilizer on Mineral Content of Rocket and Cress

Abstract

The study was carried out in the unheated plastic tunnel greenhouse and using hazelnut husk compost as a growing medium for cress and rocket plants. In the study effect of natural hazelnut husk compost enriched with organic fertilizer at different ratios content of rocket and cress minerals were investigated. Commercial organic fertilizer was added to hazelnut husk compost with nitrogen content of 1, 2, 3 and 4% of growing medium. Hazelnut husk compost are accepted as control applications. The research was set up in a trial design with 3 repeatable random parcels. Cultivation is made in plastic balcony type pots and every pot is accepted as a recurrence of application. Seed sowing (2 g/m2) was carried out in two periods, 10 September in autumn and April 28 in spring. The plants were harvested twice in both growing periods. Nitrogen, phosphorus and potassium contents were determined in plant samples after harvesting. In the study, it was seen that the application of organic fertilizers had statistically significant changes in mineral contents of cress and rocket plants. With the addition of organic fertilizers, the content of nitrogen, phosphorus and potassium is increased in rocket and cress. Mineral material content was found to be high in the autumn period and first harvest. The mineral content of the cress was higher than the rocket plants.
