To gain further insight into this situation, we compared the soil physico-chemical properties of termitaria and their surrounding soils in three Nigerian ecological zones including savannah, derived savannah and rainforest. Parameters evaluated were the pH, cation exchange capacity (CEC), organic carbon (OC), available phosphorus (Av.P) and total nitrogen (TN); base saturation (BS) and soil texture were also determined alongside the elemental (K, Na, Ca, Mn, H, Al) composition. The pH, OC, Av.P and TN in the termitaria were significantly higher than those in the surrounding soils. There were significant differences in the composition of the elements among sites in the termitaria and surrounding soils. The predominant analyte in the termitaria was Al, being in significantly higher concentration than in the surrounding soil. Na and Ca were also much higher in the termitaria than the surrounding soils in the guinea savannah zone. Soil pH had strong positive correlation with OC and CEC in the termitaria soil, but negative correlation with the surrounding soils outside the termitaria. On the other hand, both the termitaria and surrounding soils, base saturation, cation and soil texture were highly correlated between the ecozones. The findings from this study might promote nature conservation and enrichment of biodiversity in the different ecological zones, and could also support the local and poor farmers’ decisions in growing specific crops closer to the termitaria, especially the crops that require higher uptake of OC, N, Na and Ca for their growth and yields.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 3","pages":"509 - 518"},"PeriodicalIF":1.4,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140257532","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}

In this context, this study aimed to investigate the impact of acai palm plant age on total and effective Mg requirements, as well as on the accumulation, use, and dynamics of this nutrient. The experiment was conducted in a commercial acai palm cultivation area in Tomé-Açu, Pará, Brazil. The experimental design used was in strips, with six treatments corresponding to different crop ages (2, 3, 4, 5, 6, and 7 years), with four replications. The results demonstrated that the Mg accumulation in different parts of acai palm plants increased with plant age up to a certain point, showing a tendency to stabilize at more advanced ages. Furthermore, variations were observed in the rates of immobilization, recycling, and export of Mg throughout the plant ages, with greater immobilization at the expense of recycling and export. Total and effective Mg requirements also increased with the advancement of plant age. In conclusion, the age of acai palm plants influences both total and effective Mg requirements, as well as the processes of nutrient use. This information is relevant for appropriate nutritional management of acai palms, aiming to ensure an adequate supply of Mg throughout the plant’s life cycle and maximize its growth and yield.</p></div>","PeriodicalId":7553,"journal":{"name":"Agricultural Research","volume":"13 3","pages":"498 - 508"},"PeriodicalIF":1.4,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142410619","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}

Times-series data from 1981 to 2020 were obtained from the Central Bank of Nigeria Statistical Bulletin, World Development Indicators, FAOSTAT and World Bank Climate Change Knowledge Portal. Leveraging on the autoregressive distributed lag model (ARDL) and threshold analysis the study revealed that 1% increase in annual days with heat index &gt; 35 °C will cause a significant decrease in poultry production by 0.14% in the long-run. In addition, the coefficient of annual maximum number of consecutive dry days was positively related to poultry production. It was revealed that 1% increase in rainfall will cause a significant increase in poultry production by 0.84% in the long-run and 0.60% in the short-run. The study further indicated that 1% increase in GNI per capita will lead to a 0.38% increase in poultry production in the short-run and 0.54% in the long-run. In accordance, the official exchange rate of the naira was also positively related to poultry production and 1% increase in official exchange rate tends to result in 0.04% and 0.05% increases in poultry production in the short-run and long-run. However, increase in value of loans guaranteed to the poultry sector appeared to be insignificant and could assist the poultry farmers in sourcing for poultry inputs targeted at increasing poultry production. According to threshold analysis, the country's poultry output may be negatively impacted by rainfall and dry days above certain threshold levels, which are 122–135 days and 1146–1237 mm, respectively. The findings of the study present an opportunity for poultry farmers in Nigeria to embrace climate smart agricultural practices in the face of changing climate in Nigeria.

Primary data were collected through an intensive survey with rice farmers, paddy and rice traders, and millers. We employed a snowball sampling technique and evaluated 30 different supply chains as case studies to find out the varietal sources of different rice brands. The results show that BR28 was the most popular rice brand, representing about 40% of the rice available in the Upazila-level markets, followed by Miniket (17.7%), Swarna (14.5%), BR29 (12.1%), and others (15.7%).

We explored the varietal origin and found that the brand name Miniket is given to every kind of rice that falls under the medium-slender-type grain category. The market traders concentrated on producing the top four to five rice brands without exercising competition. Producing rice brands by over-polishing and receiving returns from by-products are indeed a double-edged benefit for millers, whereas consumers are paying more for finer polished rice without considering its nutritional value.
