NTERACTIONS AMONG phosphorus (P) and micronutrients may greatly influence plant growth soil productivity.Thus, a greenhouse investigation of complete randomized design was conducted to highlight such interactions in which clayey (enriched with either 5 mg Fe kg -1 , 1mg Mn ,or 1.5 Zn soil) received P the form calcium superphosphate at three rates equivalent 6.7 (P1), 13.4 (P2, recommended dose) 20.1 (P3).Then, planted maize seeds (Zea mays L var f16) for 60 days.Our results showed that application P3, but not P2, raised significantly fraction extracted by ammonium bicarbonate-diethylene Tri amine penta acetic acid (AB-DTPA-P) versus P1.Likewise, AB-DTPA extractable increased increasing rate applied P, while extractable-Zn decreased.In P-Fe interaction experiment, dose enhanced dry weights, although did affect their heights.This is because applications led significant increases K contents within tissues.Regarding P-Mn interactions, P2 content plants highest (P3) diminished this content.In spite that, weights seemed be comparable between P2and P3 both exhibited higher than P1.Finally, P-Zn revealed N due fertilizer.Accordingly, significantly.In conclusion, doses or even less need absorb more micronutrient (Fe, Zn) from metabolism growth; yet, high inputs uptake uptake.

Abstract Potato ( Solanum tuberosum L.) is one of the major crops in Africa with potential improving food and nutritional security. cyst nematodes (PCN), Globodera pallida G. rostochiensis have more recently been reported as a new pest challenging production crop region. This review analyses development selection PCN resistant cultivars control strategy focus on sources host resistance existing cultivars. A limited number studies were found. Despite this, there multiple resistances particularly among originally sourced from Europe grown by farmers proposed identification utilization already adopted an immediate for while waiting long-term solution to problem.

To solve rising fertilizer costs and preserve environment from pollution in addition decrease mineral fertilization with using organic fertilizers on leafy vegetables that used salad, a field experiment was done to investigate the impact of irrigation treatments (magnetized water normal water) different rates N vermicompost (100% N, 75% + 25% vermicompost, 50% 100% vermicompost) crisphead lettuce growth quality. The results cleared magnetized gave highest values vegetative growth, ion concentrations, yield Furthermore, fertilized exhibited yield, chlorophyll contents Mg percentage, while plants quality plants. Thus, it is recommended irrigate vermicompost. This treatment can help production by high yield.
