Opis:
The study focused on the profitability of pigeon pea production in Riyom LGA of Plateau State. Data for the study were obtained from both primary and secondary sources. Questionnaires were administered to 80 targeted farmers to get information on their socio-economic characteristics, years of experience in pigeon pea production and the reason for growing pigeon pea. The analytical tool used includes descriptive statistics to analyze the socio-economic characteristics of the farmers and farm budgeting technique (gross margin analysis) for assessing the profitability of pigeon pea production. The study also identified the constraints encountered by farmers such as high cost of labour, inadequate processing / storage facilities, problems of access to credit/loans and weed/pest infestation. The results shows that pigeon pea production is profitable with a total variable cost (TVC) at N22620.68 per ha, while gross revenue (GR) was N50185.25 per ha, the profit margin (GM) at N32564.59 and the net return per Naira invested was N0.69. It was recommended that farm inputs and improved seed varieties should be made available to farmers at affordable rates so as to enable them operate at a commercial and profitable level of pigeon pea production. These farmers should be encouraged to form a cooperative society so as to alleviate the problem of credit/ loan acquisition and procurement of genuine products as well as avoid exploitation.

Opis:
This paper reports the synthesis, crystal structure, surface morphology, optical and electrical properties of Mg-doped Sn₂S₃ thin films deposited by spray pyrolysis technique. All the films exhibit orthorhombic crystal structure with a (211) preferential orientation. Crystallite size calculations based on the Debye-Scherrer formula indicated that the Sn₂S₃ crystallite size increases with Mg content from 27.97 nm to 33.58 nm. Scanning electron microscopy images showed that all the films were very smooth composed of nanoneedle and nanoplate shaped grains. The band gap energy of the films exhibits a blue shift from 1.94 eV to 2.09 eV with increase in Mg concentration. Resistivity values of the undoped and Mg-doped Sn₂S₃ films were found to be in the order of 0.1 Ωcm. From the obtained results it is observed that the Sn₂S₃ film coated with 2 wt% Mg concentration exhibits better physical properties.
