Fields experiment were conducted to evaluate the relationships existing between mineral nqutrients in the soils and pineapple plants. Thirty - two Soil samples were collected within the experimental plots at the depth of 0-30 cm using a soil auger. Thirty- two pineapple plants of 18 months old were equally collected within the same experimental plots. Randomization method was used for soil and pineapple plants samplings. Samples were labeled and processed for soil and plant laboratory analyses. The parameters analyzed were: Total nitrogen, Available phosphorus, potassium, calcium and magnesium. Their mean concentrations in the soils and pineapple plants were: 0.59 % and 1.22 g kg -1 Total N; 15.53 mg kg -1 and 0.42 g kg -1 Available P and 0.11 cmol kg -1 and 1.3 g kg -1 Potassium. Others means value were 2.86 cmol kg-1 and 0.86 g kg -1 Calcium and 0.75 cmol kg -1 and 0.52 g kg -1 Magnesium respectively. Moreover, the concentrations of other chemical properties in soils were : 0.77 % organic carbon, 4.5 of Soil p H, 0.08 of Exchangeable Sodium and 65.9 cmol Kg -1 base saturation. The results further revealed that total N , K and Mg associated positively but weakly correlated, while Calcium associated positively but strongly correlated .Available Phosphorus associated negatively but strongly correlated between the soils and pineapple plants. The levels of mineral nutrients’ concentration in the soils at the experimental plots were low, which reflected remarkable in the pineapple plants. Inorganic fertilizers such as N. P. K 15:15:15 should be cautiously applied to enhance soil nutrients’ concentration.

The specific objectives of the study are to; identify improved rubber production technologies disseminated to farmers, identify methods for disseminating information on improved rubber production technologies, determine levels of adoption of improved rubber production technologies and finally to determine effects of adoption of improved rubber production technologies on income of farmers in the study area. A simple random sampling technique was used in selecting both adopters and non-adopters of improved rubber production technologies in the study area. Primary data generated from the survey were analyzed using descriptive statistics such as percentages, frequencies, averages, paired t-test analysis and grading scale models. The result showed that about 15 different improved technologies were identified by farmers. Extension agents were found to have eight effective methods of disseminating information to farmers. The t-test analysis showed that adoption of improved rubber production technologies increased farmer’s income. It was also revealed that the level of adoption of these technologies in the study area were above average, this calls for concerted effort by both researchers and extension agents to ensure adequate and timely dissemination of technologies that suit the needs and interests of the rubber farmers.

The study analyzes cost efficiency in food crop production among small-scale farmers in Adamawa State, Nigeria. Specifically, the socioeconomic characteristics of food crop farmers in the study area were described, their various cropping systems identified and the cost efficiency indices of the farmers determined. Data were collected from 360 randomly selected food crop farmers in eight local government areas spread across the four ADP zones of the State using structured questionnaires. The analytical tools were descriptive statistics involving the use of frequency tables and inferential statistics involving the use of stochastic frontier cost function. The result revealed that married female farmers constituted majority (57.22%) of the respondents. Their literacy level was high, as 84% of them had some form of formal education. The respondents cultivated an average of about two hectares of farm land using personal savings. Eleven cropping systems were identified with mixed cropping accounting for about 53% of the cropping systems and about 54% of the total hectarage allocations. The maximum likelihood estimates of the stochastic cost function revealed that the explanatory variables; extension contact, crop diversification and credit availability were significantly and positively related to cost efficiency in the study area. The cost efficiency index ranged from 0.18-0.98, with a mean of 0.84 implying that an average farm in the study area has the scope for increasing cost efficiency by 16% given the existing technology. The study recommended farmers education on fundamental farm management skills to enable farmers plan, evaluate and appraise their farm business activities among others.

The cracked beans were subjected to three processing methods viz: soaking in plain water for 48 hours, cooking for 90 minutes, and toasting on open fire at 100 o C after sundrying. The processed beans were milled to pass through a four mm mesh and used for diet formulation. Six experimental diets were formulated each at brooding and rearing phase, with diet 1 as control, while soybean meal in the control diets were replaced with the horse eye bean meal (HEBM) at 15, 30, 45, 60 and 75% in diets 2, 3, 4, 5, and 6, respectively. Three hundred and sixty (360) day-old Lohman black pullet chicks were used at brooding phase, while two hundred and seventy (270), 56 day – old chicks were used during the rearing phase of the experiment. Chicks were divided into six (6) groups on weight equalization bases and groups randomly placed on one of the six diets. The feeding trials lasted for eight weeks at brooding stage and twelve weeks during rearing period. Data generated were statistically analysed using analyses of variance procedures. The results revealed that level of HEBM in the diet did not significantly influenced the average daily feed intake, average daily weight gain and feed conversion ratio. Cost of feed consumed and cost per kg weight gain were significantly reduced with the inclusion of HEBM in pullet chicks’ diets. It was concluded that 45 per cent of the soybean meal could be replaced by the HEBM in diets of pullets at the chick phase while HEBM can replace 60% of the soybean meal in the pullets’ diet at rearing phase.

Two varieties of onion ('Violet de Galmi' and 'Red Creole') were combined with normal, additional 2, 4 and 6 hours after darkness in a completely randomized design with four replications. The results showed that the mean weight of bulb, size of bulb, diameter of bulb, length of bulb and the mean number of rings per bulb increased with increasing day length extension, ranging from 119.74 g to 223.23 g; 15.39 cm - 25.04 cm; 5.69 cm - 8.60 cm; 4.31 cm - 5.76 cm and 6.13 - 10.25 rings respectively. The variety ''Violet de Galmi'' exceeded the variety ''Red Creole'' in all parameters except the mean bulb length, where it was 4.97 cm as against 5.03 cm in the variety ''Red Creole''. There was significant day length extension and variety interaction on the mean bulb-weight, bulb-size, bulb-diameter, bulb-length and the number of rings per bulb. The variety ''Red Creole'' was observed to be more affected by longer day length extension than the variety ''Violet de Galmi'' in the Jos-Plateau environment.

Five new white yam genotypes were evaluated in different locations of major yam producing areas; Umudike, Nsukka, Ubiaja, Abuja and Katsina-Ala, to test the performance and stability of these genotypes across the environments using GGE bi-plot software. The GGE bi-plot generated several graphic bi-plots which showed Umudike, Nsukka, Ubiaja and Katsina-Ala as belonging to one mega – environment while Abuja and Ubiaja belong to another. The GGE bi-plot also showed the discriminating and non-discriminating environments. Katsina-Ala was the most discriminating environment while Nsukka was the least. A test environment that lacks discriminating ability lacks the capacity to provide information about the genotype being used. Such environment lacks usefulness and should be discarded as a test environment. Katsina-Ala, with the longest vector is the most discriminating.
