Field Evaluation Of Struvite As A Phosphorus Source, Niyi Sunday Omidire
Field Evaluation Of Struvite As A Phosphorus Source, Niyi Sunday Omidire
Graduate Theses and Dissertations
Phosphorus (P) is an element that is crucial in many biological processes in all forms of life and is not substitutable. Excess P in wastewaters leading to the degradation of receiving waters or eutrophication once released is a major environmental concern. Removal of excess P from wastewater as the mineral struvite (MgNH4PO4·6H2O) could be a promising solution to reduce P discharge into receiving waters and can potentially provide a valuable fertilizer-P source for agricultural production. The objectives of this project were to evaluate the effects of: 1) chemically precipitated struvite (CPST), compared to triple superphosphate (TSP) and an unamended control …
Evaluating Silicon Foliar Sprays As A Strategy To Improve Postproduction Performance Of Potted Basil (Ocimum Basilicum L.), Joshua Tebow
Evaluating Silicon Foliar Sprays As A Strategy To Improve Postproduction Performance Of Potted Basil (Ocimum Basilicum L.), Joshua Tebow
Horticulture Undergraduate Honors Theses
The objective of the study was to evaluate foliar silicon (Si) applications for effects on the growth and performance of container-grown basil during production and resistance to postproduction wilt in retail. Basil (Ocimum basilicum ‘Genovese’ L.) seedling plugs were transplanted into 10-cm diameter plastic containers with peat-based substrate and grown for 42 d in a polycarbonate greenhouse. Plants were irrigated with fertilizer solution consisting of a 17.0 nitrogen (N)-1.3 phosphorus-14.1 potassium water-soluble fertilizer dissolved in tap water at 150 mg∙L-1 N. Foliar sprays containing sodium silicate at 0, 50, 100, 200, and 400 mg∙L-1 Si mixed with deionized water were …
