Potassium release rate constant an indicator for ability supply A field experiments sulaimani governorate was conducted evaluate effect amendment with natural zeolite at (0 and 2 t ha-1), three levels Nano fertilizer (0, 5 10 kg conventional K...

Fusarium wilt is one of the main diseases of cucumber, and bio-organic fertilizer has been used to control Fusarium wilt. In this study, a pot experiment was conducted to evaluate the effects of bio-organic fertilizer applied at four levels on the suppression of Fusarium wilt disease in cucumber, the soil physico-chemical properties and the microbial communities. In comparison with the control ...

Factorial experiment according to split-plot system so that were placed main-plot, while nano...

Three-year-old citrus trees were grown in the greenhouse to study the effects of fertilizer concentration and root herbivory on plant growth and mineral concentration. In separate experiments, sour orange (Citrus aurantium L.) and Swingle citrumelo (C. paradisi Macf. Poncirus trifoliate L.) plants were treated with a complete fertilizer diluted to provide 25, 100, 200, or 400 ppm N and grown fo...

Sweet potato (Solanum tuberosum), a staple tuber crop in parts of the Sudan and Guinea savanna zone of Nigeria is known for its resistance to drought, vigorous early growth and low input requirements. Increase in population which has resulted to land shortages has led to reduction in traditional methods of maintaining soil fertility. Technologies based on combinations of organic and inorganic s...

Bush bean, long bean, mung bean, and winged bean plants were grown with N fertilizer at rates of 0, 2, 4, and 6 g N m(-2) preceding rice planting. Concurrently, rice was grown with N fertilizer at rates of 0, 4, 8, and 12 g N m(-2). No chemical fertilizer was used in the 2nd year of crop to estimate the nitrogen agronomic efficiency (NAE), nitrogen recovery efficiency (NRE), N uptake, and rice ...
