Two field experiments were carried out to evaluate the effects of Moringa leaf extract on the growth, yield and yield components of snap bean. The results showed that Moringa leaf extract applied at 11, 20, 33 and 50% concentration to snap bean plants at 10 days after emergence significantly (P ≤ 0.05) increased vegetative growth, leaf chlorophyll content, plant dry matter (shoot and root), yield components and fresh pod yield. The snap bean response to increasing Moringa extract concentration... read more

odify the soil physical properties. Organic manures are excellent sources of organic matter but relatively low in nutrients; therefore, to obtain optimum yields from continuous cropping, additional nutrients from N.P.K. fertilizers will be needed to compliment organic fertilizer. However, Akoroda (1990) reported that the use of organic manure and N.P.K. fertilizer supplies appreciable cash income to peasant farmers. Since the majority of farmers active in arable crop production in Nigeria are p... read more

.1% and 0% w/w) of crude oil and were designated P4, P3, P2, P1 and P0 respectively. Three seeds of beans per pot were planted. Growth parameters (plant height, stem girth, relative water content (RWC), and soluble protein content (SPC)) and antioxidant indices were determined in the beans over a period of nine weeks after planting (WAP). Results showed that growth of beans planted in contaminated soil was significantly lower (p<0.05) than that of control. Beans planted in the contaminated soil ... read more

oil: The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles. Testing: In general, testing is finding out how well something works.The means by which the presence, quality, or genuineness of anything is determined; a means of trial. Awareness: Having knowledge that something exists, or understanding of a situation or subject at the present time based on information or experience.

he need to use fertilizers has come into better appreciation as farmers realize its importance in improving the low nutrient status of tropical soils. As population increases, most of the cultivatable lands are taken up for uses other than crop production. Despite advances in the technique of agricultural production, significant proportion of the current world population is undernourished, primarily the underdeveloped nations (John L. Halvin et al., 2014). It is reported that our soils cannot su... read more

patial relates to space and position, size and shape of things in it; that is changes taking place within this period. Spatial variability occurs when a quantity that is measured at different spatial locations exhibits values that differ across the locations. The spatial variability of soil properties is poorly understood, despite its importance in designing appropriate experimental sampling strategies. As preparation for a farm-scale agro-ecosystem services monitoring project, the Cross River B... read more
