EFFECT OF CRUDE OIL AND BIOSTIMULANT (BIOREMEDIATION) ON GROWTH EXTRACT OF MAIZE (ZEA MAYS (L.) AND COWPEA (VIGNAUNGUICULATA (L.) WALP)

The phytotoxic effects of crude oil concentration in soil on growth extracts – Relative growth rate (RGR), Relative leaf growth rate (RLGR), Leaf Area ratio (LAR) and Net Assimilation rate (NAR) of maize (Zea mays (L.) and cowpea (Vigna unguiculata (L.) Walp) was examined. The beneficial effects of bioremediation with addition of Biostimulant – Sawdust on the growth maize and cowpea in an oil contaminated soil was also determined. It was observed that crude oil contaminated soil (400ml) per plot was phytotoxic to both crops. In contrast, obvious phytotoxicity was observed in soils planted with maize. In addition, bioremediation with Sawdust reduced phytotoxicity and increase the growth indices of crops during the study

Effects of International Fund for Agricultural Development (IFAD) Credit Supply on Rural Farmers in Rivers State, Nigeria.

The study evaluated the effect of IFAD credit supply on rural farmers in Rivers State. Data for the study were collected using a structured questionnaire administered to 90 farmer’s beneficiaries using a multi-stage sampling technique. The regression result shows that semi-log function gave the best fit with the highest value of coefficient of multiple determination (R2) of 0.8758 and seven explanatory variables were significant and a significant F-value. The significant variables are farm size, off-farm income, total household labour, and educational level of farmer, gender, farm household size and IFAD credit. The study also shows that IFAD credit impacted positively on the well-being of rural farmers. The IFAD programme has contributed to increase in farm output and income. The study recommended that IFAD and their collaborating government agencies should expand their credit delivery in the study area to enable more farmers benefit from their services. Also training programme should be organized for all farmers in view of the fact that education produced significant influence on the income of the farmers.

VARIATIONS IN FOOD CONTENT OF CROPS AS INFLUENCED BY BIO STIMULANTS IN AN OIL CONTAMINATED SOIL

A study was carried out at the University of Port Harcourt botanical garden, to determine the influence of bio stimulants on food content of crops grown at two levels of crude oil contamination. Results showed that bio stimulants (sawdust and chromolaena leaves) enhanced protein and carbohydrate accumulation in the crops. However, chromoleana leaves was more effective than sawdust while the test crops-Z. mays and Vigna unguiculata differed in their accumulation potentials in protein and carbohydrate
