Therefore, this study aims to examine changes in parameters of soil physical properties on various slopes due to the provision of types of organic matter (manure, coffee skins and <em>Gliricidia</em> leaves). This study also analys the influence of slope soil to the Napier grass production (<em>Pennisetum purpureum</em>). The study was obtained in the hilly areas of Paya Tumpi Village by using a <em>split plot organic design</em>. In deep analysis of change in parameters on the slope of the type of organic material on soil physics will be performed. The results showed that organic various types of slope and administration of various types of organic materials significantly affected the physical properties of the soil, namely permeability, porosity, aggregate stability index, fast drainage pore, slow drainage pore, available water pore, growth and yield of Napier grass. <em>Gliricidia</em> leaves compost is the best for growing Napier grass.</p> Erita ., Sandri Sastrawan, Salmandi Futra, Hairunnas . ##submission.copyrightStatement## Thu, 30 Jul 2020 00:00:00 +0000 Assessment of the Profitability of Rice Production in Afikpo North L.G.A. <p>This study was carried out to determine the profitability of rice production in Afikpo North L.G.A Ebonyi State of Nigeria between April and September, 2019. Seventy (70) rice farmers (35 each) randomly selected from two prominent rice producing villages (Amasiri and Akpoha) in the study area were used as sample size. Questionnaires and personal interviews respectively were the basic primary and secondary means of data collection. Descriptive statistics, Gross margin analysis and Likert Scale were used to analyze the data obtained for socio-economic, profitability and constraints to rice production in the study area respectively. Results showed that socio-economic characteristics including gender, age, farm size, household, education etc are among the factors that affect rice production in the area. The result of likert scale showed that inadequate capital, high cost of labour, inadequate farm input etc were major constraints to rice production, while cost of transportation, cost of pesticide and marketing outlet were not considered as constraints rice production in the area. The result of gross margin analysis showed that Total Revenue and Gross margin were 270,000 and 214, 0000 respectively while Net Profit was N201, 500. The cost return ratio was 3.9k. This implies that the rice farming is highly profitable since the total revenue significantly outweighed the total cost. The cost return ratio of 3.9k implies that for every one naira invested in rice production about 4.0k is returned as profit. The study therefore recommends that Government should formulate agricultural enhancement policies that will address the major constraints observed in this study to ensure large scale and profitable rice production in Afikpo North LGA.</p> Uche Nkechi, Donatus, Jane, N.

Among the various amendments, compost prepared from the crop residues attracted much attention in recent years. The crop residues used as feedstock are added with different bulking materials such as rice husk and sewage sludge.&nbsp; In addition to these, termite mound soil which is available in plenty in tropical countries is found to be a suitable bulking material and is added with crop residues to obtain nutrient rich compost. In this paper we reviewed researches carried out on the characteristics, microbial diversity and organic matter degrading enzymes in termite mound soil. Further, the research carried out on the characteristics of compost amended with termite mound soil and its effect on crop productivity is also reviewed with the available literature. Majority of the investigations concluded that termite mound soil possessed more microbial population with a huge array of organic matter degrading enzymes. Few studies monitored the nutrient content of the soil and water holding capacity of the soil and crop yield when termite mound soil was used as a soil amendment. Limited studies were conducted using termite mound soil as a bulking material to compost crop residues. Based on the outcome of various studies, it is understood that the termite mound soil might be used as a soil amendment to increase growth and yield of crops.</p> S. Subi, A.
