Comparative effects of organic manure and inorganic fertilizer as nitrogen sources on leaf nutrient content and nitrogen use efficiency of cotton

Omadewu, L.I.*, Kefas, P. K, Ukatu, P O, Abednego, C., Solomon Rejoice Ibrahim

A field experiment was conducted at the Research Farm of the College of Agriculture Jalingo, Taraba State in two planting seasons (2020 and 2021) to determine the influence of nitrogen sources and rates on nutrient concentration in leaf and nitrogen use efficiency of cotton. The experiment was a 5x4 factorial of four nitrogen sources (poultry manur...

Characterization, Taxonomic and Fertility Capability Classification of Some Soils in the Teaching and Research Farm of Taraba State University, Jalingo

, Ezeaku, P.I.*, Kefas, P. K, Hashim, S.A.,, Ali I J, Gisilanbe S A, Kussy J J, Garpiya B. T, Yusuf B, Udoh S, Ezeaku, V. I

Result-oriented and competitive agricultural production system requires soil characterization and land evaluation. The soils of the Teaching and Research Farm of Taraba State University were characterized, taxonomically classified and evaluated for fertility capability classification. Three mapping units were delineated using a semi-detailed survey...

Influence of Forms of Iron and Manganese Oxides on the Physical and Chemical Properties of Soils Formed Over Mica - Schist in a Northern Guinea Savanna, Nigeria

Kefas, P. K*, Abdulrashid Shobayo Babatunde, Ofem, K.I, Akwoga, J.A, Asadu Charles Livinus, , Ezeaku, P.I.

Three forms of oxides of iron and manganese were evaluated on soils developed in mica-schist lithology within the basement complex formation of Taraba State, North-eastern Nigeria. The results from the three oxide forms namely, pyrophos- phate extractable (Mnp/Fep), oxalate extractable (Mnox/Feox) and citrate- bicarbonate-dithionite extractable (Mn...

Suitability of Urban Waste Land Use in Relation to Heavy Metal and Micronutrient Influence on Soil and Green Amaranth Production in Southeast Nigeria

Ezeifeka A.O*, , Ezeaku, P.I., Ezeaku, V. I, Anikwe M. A. N, Kefas, P. K, Ofem, K.I

An assessment of the impact of long term (>20 years) MSW disposal on soil properties and their suitability for crop productivity was carried out in Anambra and Enugu States of southeast Nigeria. Four dumpsites were selected (two in each state) and, 12 soil auger samples (2 sampling points at 3 depths and 2 repeated measures) each were collected at ...

Land Suitability Evaluation for Maize Production and Taxonomic Classification of Soils Overlying Undifferentiated Basement Complex in Northeast Nigeria

Kefas, P. K*, Maigida, E, , Ezeaku, P.I., Ofem, K.I, Akwoga, J.A, Ezeaku P

Soil characterization, classification and evaluation provide useful information for the understanding of its different facets, hence their potentials and limitations for crop production. Such information is lacking in the general area of Kona-Jalingo in Taraba State, Nigeria, hence the study to determine the macro-morphological, physical and chemic...
