Soil Porosity and Water Infiltration as Influenced by Tillage Practices on Federal University of Agriculture Abeokuta, Ogun State, Nigeria Soil

 AbstractThe relations between soil pore structure induced by tillage and infiltration play an important role in flow characteristics of water and solutes in soil. The effects of agricultural management practices on soil physical parameters aid the effective sustainability of soils. In this study, three tillage methods common to the study area on porosity and water infiltration were assessed. Tillage treatments include zero tillage (Plot covered with vegetation (conservation tillage))...

Introduction and Participatoryevaluation of Exotic Cultivars of Pepper (Capsicum Spp.) among Small Holder Farmers in South- Western Nigeria

Abstract. Pepper (Capsicum spp.) production by farmers in southwestern Nigeria is limited by low yield due to poor genetic potentials of most cultivars available, use of poor quality seeds, disease infestation, and poor managment practices among others. To overcome the constraints, some varieties of pepper developed at Embrapa Brazil and NIHORT Nigeria, were introducedfollowed bytraining of 100 small scale farmers . Participatory field demonstrations of the improved varieties of pepper were c...

Effect of phosphate fertilizer application on manganese adsorption by some soils in Borno state

Abstract-The  study  was  carried  out  to  investigate  the effect  of  phosphate  fertilizer  application  on  manganese (Mn)  adsorption.  Composite  sandy  loam  and  loam  soil samples  (0-20  cm)  were  collected  from  Dalori  and Gongulong  and  analysed  for  their  texture  and  chemical properties.  Mn  adsorption  experiment  was  carried  out. Loamy soil  collected  at  Gongulong was  moderately acidic in  reaction,  moderate  in  e...

Manganese distribution in selected Rice soils of Ebonyi, Southeastern Nigeria

This research work was carried out on the rice soils of Ebonyi State, considering the Manganese distribution in upland, lowland and irrigated rice in the three Local Government Areas of Ebonyi State, namely; Abakaliki, Ikwo and Ivo LGAs in the three agricultural zones namely; Ebonyi North, Central and South. In the different locations, upland (UP), lowland (LP) and irrigated (IP) uses were considered. They were identified as AUP, ALP and AIP for Abakaliki IUP, ILP and IIP for Ikwo and IvUP, I...

NODULATION OF COWPEA

Abstract Cowpea (Vigna unguiculata [L]Walp) can obtain nitrogen from the atmosphere by the process of biological nitrogen fixation when associated with specific and effective rhizobia. The purpose of this study was to evaluate the effect of different rates of phosphate fertilizer on nodulation and dry matter yield of cowpea. A Randomized Complete Block Design with four treatments and three replications was used. The trial was conducted on the field. The treatments consisted of different rate...

INFLUENCE OF NITROGEN AND PHOSPHORUS ON NODULATION AND YIELD OF SOYBEAN

AbstractGrain legumes are getting popular all over the world, either because of their high protein or oil content and potential to improve soil fertility. A field study was undertaken with two grain legumes; Soybean and Cowpea, that are economically important in the semi-arid region at the Irrigation Research Farm of Institute for Agricultural Research, Kadawa, Kano in the Sudan Savanna to gain an understanding of fertilizer application rates on nodulation and yields of Soybean (TGx 1904-6F) ...
