Performance and quality attributes of okra (Abelmoschus esculentus (L.) Moench) fruits grown under soil applied Zn-fertilizer, green biomass and poultry manure.

Field experiments were carried out in 2018 and 2019 cropping seasons at Landmark University Teaching and Research farm, Omu-Aran Kwara state, Nigeria, to determine the effect of soil applied Zn-fertilizer, Tithonia diversifolia (Ti), Chromolaena odorata (Ch) and poultry manure (PM) on the performance, yield, minerals and vitamins composition of okra fruits. Treatments were combined and tested as follows:-Control (T), Control + 10 kg ha Zn (T), 5 t ha Ti + 5 t ha PM (T), 5 t ha Ch + 5 t ha PM (T), 5 t ha Ch + 5 t ha Ti (T), 10 t ha Ti + 0 kg ha Zn (T), 10 t ha Ti + 10 kg ha Zn (T), 10 t ha Ch + 0 kg ha Zn (T), 10 t ha Ch + 10 kg ha Zn (T), 10 t ha PM + 0 kg ha Zn (T), and 10 t ha PM + 10 kg ha Zn (T). The experiment was laid out in a randomized complete block design with four repetitions.

Different organic manure sources and NPK fertilizer on soil chemical properties, growth, yield and quality of okra.

Use of organic manures to meet the nutrient requirement of crop would be an inevitable practice in the years to come for sustainable agriculture since organic manures generally improve the soil physical, chemical and biological properties. Hence, field experiments were carried out in 2017 and 2018 to compare the impact of different organic manures and NPK fertilizer on soil properties, growth, yield, proximate and mineral contents of okra (Abelmoschus esculentus L.).

MgO Fertilizer Sole and Combined with Organic and Inorganic Fertilizers: Effect on Soil Chemical Properties, Turmeric Performance, and Quality in a Tropical Alfisol.

For soil fertility maintenance, secondary nutrient such as Magnesium (Mg) is always being neglected. However, its role is critical in the growth, yield, and quality of crops. Therefore, two field experiments were initiated in 2017 and 2018 to evaluate the response of soil chemical properties, performance, and qualities of turmeric ( L.
