A two-stage sampling procedure involving purposive and simple random sampling was used to select 250 rice farmers for the study. Data were obtained using a structured questionnaire which was administered to the farmers. The data obtained were analyzed with the use of descriptive statistics and stochastic production function through Maximum Likelihood Estimation (MLE) method using the computer program for frontier version 4.1. Results show that most (68.4%) of the small-scale rice farmers were male and 78.4% were married with mean age of 43 years, as well household size of 7 persons respectively in the study area. About 86% of the farmers had formal education, with about 13 years-experience in rice farming and an average farm size of 2.9 hectares. Most (51.6%) of the farmers had contact with Extension Agent and use hired labour (54.8%). Average farm net income for the rice farmers was ₦599,681.28 per hectare. The MLE for technical efficiency shows that farm size, seeds herbicides and pesticides use influenced output of rice production in the study area while farming experience (-2.4260), literacy level (-02.6402, age of farmers (-2.6402) and source of capital (-1.3329) respectively jointly contributed to increase farmers efficiency in the study area. The study concluded that rice farming is profitable in the study area and recommends implementation of an integrated rice farming development program combining education, mentorship, financial support, and enhanced extension services.

The use of grain such as maize in feed production for poultry is creating more shortage of maize for man with the growing population and high demand in the country. There is a need for alternative products for producing poultry feeds from agricultural waste to reduce the competition. This study was conducted to determine the growth response of broiler chickens to feeds produced from wheat offal (agricultural waste product from wheat) and maize. A total of 50 broiler chickens (day-old) were used with 25 birds (5 birds in each replicate) fed with feed made from wheat offal and 25 birds fed with feed made from maize and monitored for 12 weeks. The body weight of the broilers was recorded weekly for 12 weeks, and the feed conversion ratio was also determined. The mean weights of the broilers fed with wheat offal for day-old, weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 were 76.6, 115.6, 144.0, 186.0, 305.6, 462.6, 562.0, 693.6, 758.8, 814.4, 866.4, 956.8 and 1,032.8 g/broiler while the corresponding weights for broilers fed with maize feed were 99.6, 129.6, 151.2, 188.8, 234.8, 300.0, 386.8, 466.8, 550.8, 646.8, 732.4, 804.0 and 882.8 g/broiler, respectively. Wheat offal feed increased the body weight of the broilers by 16.99% at 12-week compared to broilers fed with maize feed.

In Nigeria, it is a staple food consumed in various forms. However, present-day domestic supply is unable to meet local demand due to various forms of challenges confronting rice producers, many of whom are smallholder farmers. The study combined an in-depth review of literature and empirical analysis framework to identify challenges in rice production among smallholder paddy farmers in Ayamelum Local Government Area of Anambra State. Specifically, the study identified the farmers’ socioeconomic characteristics, ascertained the distribution of improved technology usage among them and identified the challenges facing the farmers. Data were collected through multistage sampling technique from 90 paddy farmers and were analysed by descriptive statistics. Results showed an equal proportion of men and women engaged in the survey with majority of them being married. The farmers were in their active middle-ages and on average, had been farming for 12 years. Main findings included: rice cultivation in the area was dependent on fertilizers, extension services were rarely available and improved seeds and needed machineries were not readily available due to their high costs. The study highlighted the need to increase access to required farm inputs through various means including government agencies and farmers’ associations to help paddy smallholder farmers sustain their productions and livelihoods.

However, reclamation as well as land suitability evaluation are considered the basis and critical steps for determining the reuse direction of degraded land caused by several years of mining activities. Therefore, the present study was carried out to evaluate the land suitability for different crops production and suggest management practices for their reclamation. Parcel of land covering 224.29 ha on the northern part of Barkin Ladi in Plateau State, Nigeria was surveyed at a detailed scale of 1:6,000. Soil physical condition (petroplinthite), chemical fertility (nutrient retention and availability), low to moderate plant available water, poorly drained condition and erosion hazard were the land qualities that critically limited the suitability of soil mapping units BL II to BL V for the different crops. The evaluation showed that BL I was highly suitable under current suitability for maize, cowpea, green bean, onion and mango (55.55 % of the crops). The crop proportion rated as S1 increased to 88.88 % under potential suitability. The upgrade is expected to occur when the limitations identified are properly managed. Soil unit BL V degraded by previous mining is the least rated with most of the crops as temporarily and permanently not suitable. Land levelling or terrace construction and planting of mango as well as avoidance of bush burning were among management practices suggested to reclaim the deep gully associated with the degraded mined lands. For sustainable crops production and management of the study area; contour ridges, incorporation of organic matter and inorganic fertilizers as well as construction of drainage canals are recommended.","PeriodicalId":517354,"journal":{"name":"Journal of Agriculture and Environment","volume":"377 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139894443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three slope positions namely, lower slope (LS), middle slope (MS) and upper slope (US) were delineated, and their properties were assessed. Results indicated that soils on all locations were very deep (167 – 192 cm) with occurrence of plinthite at subsurface of MS and US. Slope position of the soils was noted to influence morphological, physical and chemical properties. Content of silt and sand fractions, available water content and moisture retention at field capacity were all significantly influenced by slope. Melanization, braunification, plinthization and argilluviation were some pedogenetic process notable in the soils. Suitability studies revealed that 29.12% of the area was moderately suitable (S2) for rice cultivation with limitations of climate, soil physical property and fertility, while 70.88% of the area were marginally suitable (S3), with an additional limitation in wetness. For cowpea, 68.13% of the soils were S2 with limitations in fertility, while MS was highly suitable (S1). Tomato was rated S2 for the entire area with general limitations in climate and fertility. Suitability for rice increased down the slope from US, while that of cowpea and tomato increased along the slope from LS to US. This effect was attributed to distribution of nutrient and water, as preconditioned by topography. Management practice suggests the use of LS for rice, while MS and US may be rotated for cultivating tomato and cowpea.","PeriodicalId":517354,"journal":{"name":"Journal of Agriculture and Environment","volume":"279 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
