“…Even though application of manure generally influenced the growth characteristics of maize plants, poultry manure showed exceptional potentials in its influence on the maize plant growth and this was progressive as the maize plant height tripled from 97.3cm to 293.4cm within a space of 21days for plots that received poultry manure treatment. This is similar to the reports of Madukwe et al (2008) and Christo et al (2008) who studied the application of poultry manure on growth characteristics of cowpea.…”

“…It was observed that poultry manure significantly amended the crude oil polluted soil when compared with the other sources of manure (Cow dung, and farm yard manure). Both Madukwe et al (2008) and Christo et al (2008) observed that poultry manure has greater potentials in amending crude oil-degraded soil by positively influencing the growth of cowpea more than the other sources of organic manure.…”

to investigate the interaction of crude oil and manure on the agronomic characteristics of maize. The experiment was arranged in Randomized Complete Block Design of a split plot fashion with four main plots represented by the levels of crude oil pollution (0 ml, 100 ml, 200 ml, & 300 ml), while the organic manure (poultry manure, cow dung manure and farm yard manure) and a control (no treatment) plots made up the subplots. The set up was replicated four times. Soil collected from the University's farm site was used to fill 64 buckets of 30 cm 3 capacity each to 2/3 of their volumes. Crude oil was applied to the buckets according to the levels. Organic manure was applied 14 days after pollution at the rate of 2Kg/20Kg of soil, while the maize seeds (Obatampa variety) were planted at 28 days after pollution. Soil samples were collected for physical and chemical analysis before application of crude oil and 28 days after application of crude oil. The germination percentage was determined two weeks after planting. Plant height (cm) and leaf length (cm) were determined at 3 and 6 wks after planting, while cob length (cm), cob diameter (cm), number of seeds per cob and weight (g) of 100 seeds were determined at maturity. Results showed that application of manure significantly influenced the growth and performance of maize plant in the crude oil polluted soil. Poultry manure significantly improved the agronomic characteristics of maize more than the cow dung and farm yard manure in the crude oil polluted soil. This indicated that poultry manure exhibited a higher remedial potential of the crude oil-polluted soil than the other organic manures (cow dung and farm yard manure). The results further showed that application of poultry manure positively interacted with crude oil and it is therefore recommended to be used in the remediation of crude oil degraded soils.

“…The enhanced growth attributes recorded from the weed free check, Pendimethalin at 4lha -1 + one hand weeding at 6 WAP, two hand weeding at 3 and 6 WAT over sole Pendimethalin at 4lha -1 and weedy check could be attributed to low incidence of weeds interference. The results agreed with the studies of Madueke (2010), Madukwe et al(2012), Imoloame et al (2014) who had variously reported better growth in all the weed control treatments than the weedy check most importantly where chemical was combined with one hand weeding. Weeds have generally be known to compete with crop for resources that are necessary for plant growth and developments (El-Naim, et al, 2010).…”

“…Further, since the crop has the ability to fix atmospheric nitrogen with rhizobia, inorganic fertilizer application is considered not much important (Kan` ankuk`a, 1999). Regardless of this N fixing ability, a positive response of cowpea to the application of organic and inorganic fertilizer has been reported by several authors from various cowpea grown areas (Madukwe et al, 2008;Singh et al, 2011a) especially they used nitrogen (Amujoyegbe & Alofe, 2003;Singh et al, 2007;Daramy et al, 2016) and phosphorus (Owolade et al, 2006;Singh et al, 2011a;Nkaa et al, 2014) fertilizers.…”

The aim of the study was to evaluate the effect of different rates of nitrogen (0, 10, 20, 30 and 40 kg N/ha) and phosphorus (0, 15, 30 and 45 kg P2O5/ha) fertilizers application on growth and yield performance of cowpea (variety Asontem). A factorial experiment was conducted in randomized complete block design with three replicates at the plantation site of Department of Crop and Soil Sciences, Kwame Nkrumah University of Science and Technology, Ghana in the major cropping season of 2014. No significant effect of N and P fertilizer application on cowpea growth and yield was reported in present study. It is thus recommended that there is no need to apply N to cowpea planted in the same fertility status fields as in the present experimental site. Further studies required to be conducted with higher P rates.
