EFFECT OF NITROGEN FERTILIZER (UREA) ON SOIL ACIDITY INDICES UNDERLOWLAND RICE CULTIVATION IN YOLA, NIGERIA

Alhassan I^*, Saddiq A M, Singh L, Timon F

The experiment was conducted for two years to determine the effect of N fertilizer application rates (0, 50, 100 and 150 kg/ha on grain yield, pH, calcium (Ca), magnesium (Mg), base and acidity saturation of the soil in FARO 44 lowland rice cultivation. Grain yield was significantly (P= 0.05) affected by the N fertilizer rates; it increased linearly with N rates. The grain yield increased was by 4...

CORRELATION AND PATH CO-EFFICIENT ANALYSESFOR YIELD AND ITS CONTRIBUTING TRAITS IN FINGER MILLET(ELEUSINE CORACANA (L.) GAERTN) AT SAMARU IN THE NORTHERN GUINEA SAVANNA OF NIGERIA

Gani M^*, Shinggu C P

The treatments consisted of three seed rates (3, 6, 9 kg ha-1), two sowing methods (broadcasting, dibbling) and three poultry manure rates. The experiment was laid out in a split plot design with three replications. A factorial combination of sowing method and poultry manure rate constituted the main plot, while seed rate occupied the subplots.In all the years, there was a strong andpositivesignif...

EMPIRICAL MODELS ASSOCIATED WITH GULLY DEVELOPMENT AND PREDICTOR VARIABLES INFLUENCING LITHOSOL SOIL IN GIREI LOCAL GOVERNMENT AREA, ADAMAWA STATE, NIGERIA

Gundiri J.W.^*, Buji I. B., Kwari S. J., Akwoga J. A, Joshua B.N.

A 2-year field study was carried out in Girei to evaluate the relationship between dependent variables (volume, Area and Mass of soil loss) and independent variables (watershed characteristics and related soil hydro-physical properties) by developing a regression model. This prediction model revealed how predictors impacted gully erosion development in 41 different gully locations. The results of ...

EVALUATION OF SOME PRE- AND POST- EMERGENCE HERBICIDES FOR WEED CONTROL ON GROUNDNUT (Arachis hypogea L.) IN NORTHERN NIGERIA

Ishaya D B^*, Fatokun S O, Haruna M

Field trials were conducted in the wet seasons of 2014 and 2015 to evaluate the effect of Pre- and Post-Emergence herbicides for weed control and performance of groundnut to address the problem of low yield due to weed interference in the crop. Among the ten weed control treatments evaluated in a Randomized Complete Block Design (RCBD) replicated three times, the mixtures of metolachlor + prometry...

ASSESSMENT OF NURSERY GROWTH MEDIA FOR SEED GERMINATION, SEEDLING GROWTH AND DEVELOPMENT OF AIDON SPICE (Tetrapluera tetraptera) TREE IN SOUTH-EASTERN NIGERIA

Peter Onoh C A^*, Obiefuna J C, Ngwuta A A, Ogoke I J, Ihenacho L U

Good seedling quality is the basis for tree planting success which accounts for higher survival and faster growth rate in the field. A study was carried out to evaluate the effects of different growth media on seed germination, seedling growth and development of Aidon spice tree (Tetrapluera tetraptera) seedlings in the nursery unit of Teaching and Research Farm of the School of Agriculture and Ag...

EFFECT OF HYDRAULIC HEADS ON WATER APPLICATION RATE, VARIATION AND UNIFORMITY COEFFICIENT ON DRIP IRRIGATION SYSTEM

Adamu Abdullahi Musa^*, Alhassan I, Bashir A Y

The study evaluated the performance of drip irrigation system under different hydraulic heads using drip giving set as emitter. A plot was equally divided into three sub-plots and three lateral each with 2.4m length were laid on the ground. A plastic tank reservoir was provided to each plot with metal stands which suspended the tank from the ground surface. The height of the tank were varied from ...

QUALITY ASSESSMENT OF IRRIGATION WATER OF KANO RIVER IRRIGATION PROJECT (KADAWA SECTOR)

Nuhudeen Z. O^*, Adamu A, Ibrahim F B

The quality of water used for irrigation is a very important aspect of irrigated agriculture as the use of poor quality irrigation water affects the crop and the physical conditions of the soil. This work assessed the irrigation water quality of Kano River Irrigation Project (Kadawa sector). Water samples for the pre and post irrigation water were collected and tested for electrical conductivity, ...
