This study investigated the level of substitution of fresh fruit for processed fruit and what influences consumers’ preference for purchase of fresh citrus or processed citrus in Oyo State. Well-structured questionnaires were used to collect information from 100 respondents using a two-stage sampling technique. Descriptive statistics and probit regression were used to analyze the relationship of socioeconomic factors and respondents’ opinion with regards their preference for fresh or processed citrus fruits. From the result of the study, a good number of respondents prefer fresh to processed citrus fruits. The study also revealed that the opinion or perception of the respondents in relation to cost of purchase, nutritional content, negative or positive implication on health influences their preference for fresh citrus while convenience, cost of purchase and nutritional content influence preference for processed citrus fruits. Majority of the respondents indicated that processed citrus may have negative health implications.

In the context of overcoming the COVID-19 pandemic consequences, the concept of total quality management should serve as the basis for rethinking the role of customer service for travel services, in accordance with the requirements of the international service quality standards. The paper aimed to approach the theoretical, methodological and practical problems of assessing the quality of the travel services of regional enterprises that organize rural tourism tours in Ukraine. The main attention was paid to the analysis of the quality of components of standard travel services on the directions of rural tourism routes having hidden features. To assess the services quality, in accordance with their latent features in the field of rural tourism, the authors used the benchmarking methodology, which combines the number of statistical comparison methods based on multidimensional objects. The article offers an algorithm for the benchmarking of the quality of services provided by rural tourism tour operators. As part of the benchmarking tools for assessing the quality of service provided by travel business entities, the authors used the taxonomic analysis method. The approaches proposed by the authors to assessing the quality of travel services allow rural tourism business entities to form the measures to restore the sale and rendering of travel services in the context of overcoming the COVID-19 pandemic consequences.

The paper studied the assessment of potato growing potential on organizational and economic bases in Ukraine. The materials presented according to specificity of production rates and conditions from 1940 to 2018. On the basis of the gross potato production indicator in Ukraine for 78 years (from 1940 till the current state), indicators and tendencies of potato growing development are determined. From the standpoint of potential vectors of zonal specialization (ZSP) and standardized raw materials sources (RMS) such realization was investigated. The survey has found, that the main principles of end-to-end coordination in potato growing industry of Ukraine depend on agricultural enterprises and farms input in the short and medium term and on households in the long term perspectives. The data showed that the technologies involved in potato growing still need systemic improvement and development towards convergent ones with the level of realization of the genetic potential of productivity for more than 70%.

There is the need to rethink how technology is being disseminated to end users in order to ensure adoption and utilisation. This study assessed how pull mechanism is enhancing the utilisation of Aflasafe bio-control measures among maize farmers in Oyo State, Nigeria. Multi-stage sampling procedure was used to select 91 maize farmers for the study. Data was collected from maize farmers through interview schedule and analysed using descriptive statistics (means, frequencies and percentages) and inferential statistics (Pearson Product Moment Correlation and Regression analysis). The result showed that 89% of the farmers indicated Implementers as the outlet for the purchase of Aflasafe. Also, premium payment and provision of technical assistance were the highly ranked incentives to utilisation of Aflasafe among the farmers. The study also revealed low access to credit as major constraint to the utilisation of Aflasafe bi-control measures. Meanwhile, 54% of the farmers had full utilisation of Aflasafe in maize production. Significant correlation was found between incentives and utilisation of Aflasafe (r-value = 0.274; p≤ 0.01). The study therefore recommends that governments and non-governmental organisations should ensure availability of Aflasafe bio-control to the maize farmers either through loan provision or price subsidy.

It is expected that after the COVID-19 pandemic, mass travel is unlikely to be as popular, although it will be relatively cheaper. Tourists will look for more individualization and consumer interest to be focused on a better quality tourist product, guaranteeing them greater security and safety. It is through family hospitality that customers' preferences are satisfied for comfortable, secluded and safer accommodation, with an original atmosphere, such as family hotels and guest houses, with reasonable prices, with fair cleanliness, combined with natural and unadulterated natural and social environment, in ecologically clean areas. In the present study, an assessment of the quality of the hotel product in family sites for accommodation in rural tourism in rural, mountain municipalities in Bulgaria. An evaluation methodology has been developed. The selected quality assessment criteria are divided into basic and additional. Each criterion is formalized by five quantifiable indicators. The aim is to fully cover the composition, structure, specifics and activities of the family hotel business. The obtained results were analysed and conclusions were made.

Since 2007, the GM maize event MON 810 (resistant to insects Lepidopteran) is authorized for cultivation in Romania, but since 2016 the farmers have given up cultivating it for various reasons. In this study, the main agronomic parameters of genetically modified (GM) maize hybrid (MON 810 - trade name: DKC 5784 YG) and of two conventional maize hybrids (Deliciul verii and F 376) were compared under drought and heat conditions during two years at Agricultural Research and Development Station (ARDS) Șimnic. The hybrid affected statistically significant (P≤0.05) all evaluated parameters. Similarly, climatic conditions (year) significant influenced all evaluated parameters with the exception of the days to tasseling. The GM hybrid confirmed ability to protect itself against the Ostrinia nubilalis (ECB) and the drought, and its average grain yield was higher by 1.33 - 1.69 t/ha in comparison with conventional maize hybrids. The results showed a higher level of attack on conventional maize hybrids in extremely dry year 2012 compared to 2013. Thus, adopting GM maize crops can effectively address the drought stress and its consequences for sustainable maize crop production in the dry Oltenia region.

Tea Camellia Sinensis (L) Kuntze is from the family of Theaceae. Tea plant encompasses some 200 woody plants species in the warmer regions of Asia and South America. Tea in its natural habitat develops to a small plant producing flower at six years or less or more based on type of variety and means of propagation. Total area of land under tea cultivation in the world is about 2,600,000 hectares with 86% in Asia, 85% in Africa and the remainder across South America, Russia and Oceania. The highest producer of tea in the world is Asia (60%), followed by Africa(12%). The countries in Africa which are large tea producers are Kenya, Malawi, Burundi and Cameroon. Nigeria still produces tea in small quantities as compared to Kenya. This study therefore examined the challenges to tea production and tea marketing in Taraba State of Nigeria. When these challenges are met tea production will be boosted and probably exported to improve the country’s economy. The study was carried out in Taraba state in Nigeria. Data was collected through the administration of well-structured questionnaire among tea producers and marketers (272). Proportion to size sampling technique was used. In Taraba state, three communities were selected namely Mayo-Kusuku, Kakara and Kasalasah. Based on the population of tea farmers 90, 90, 92 were selected respectively from the communities. The result revealed that, thirty six percent of tea producers were between 17-30 years old, 50% of the producers were between 31-60years while 15% were above 60years. Majority of the producers are male(92.7%) while 7.3% were female. Twenty four percent of the producers have no formal education while seventy six percent have either primary, secondary or tertiary education. The challenges faced include poor soil fertility, low yield, pest infestation, labour shortage, lack of finance and lack of fertilizer/pesticide. Eighty six percent of tea producers lacked finance while 83.8% lacked fertilizer/pesticide. The problems faced by tea marketers in Taraba State are low market demand, low price, lack of access to market and high cost of transportation. Seventy five percent of tea marketers faced the problem of low market demand. Tea producers and marketers in Taraba State have great potential for development. Tea business can bring about economic development in Taraba State and Nigeria as a whole if government at various levels can put in place intervention programmes to overcome these challenges.

In the article we proved that the clustering of regions in terms of socio-economic conditions of rural development and farms located on them using a selected range of indicators by scientists was not carried out. The obtained results provide an opportunity to conduct a comprehensive assessment and generalization of the territorial differentiation of socio-economic conditions for the development of rural areas and farms located in the Volyn region of Ukraine. Visualization of the territorial-spatial distribution of selected clusters using a cartogram allows optimizing the visual perception of the information load on the clustering results. The general generalizations of regional differentiation of separate elements of social and economic conditions of development of rural territories and peasant farms located on them for real realities prompt to think about perspective prospects of development of the system of these farms, their place, and role in the organizational structure of agrarian sector of market type.

The present study aimed to analyze and characterize five gladiolus varieties, based on flower quality parameters in relation to some vegetation indices. The studied gladiolus varieties were: 'Plumtart' (Plu), as control variant (Mt), 'Flower Song' (Flo_S), 'Tequendame' (Teq), 'Princess Margaret Rose' (PMR), and 'Praha' (Pra). For the comparative analysis of the five gladiolus varieties, vegetation indices and flower quality parameters were used: vegetation period until flowering (VPuF), plant height (PH), floral stem number (FSN), inflorescences length (IL), flowers number (FN), flowering time (FT), and total vegetation period (TVP). Inflorescences length (IL) recorded values between 30.33 cm for the 'Praha' (Pra) variety and 64.00 cm for the 'Flower Song' (Flo_S) variety. The flowers number (FN) in the inflorescence registered values between 12.50 for the 'Praha' (Pra) variety, and 19.17 for the 'Flower Song' (Flo_S) variety. Flowering time (FT) varied between 24 days for 'Praha' and 'Flower Song' varieties, and 28 days for 'Princess Margaret Rose' and 'Plumtart' varieties. The regression analysis facilitated the obtaining of equations that described the variation of the flowers number (FN) in relation to the flower stem number (FSN), and inflorescence length (IL), respectively the variation of FT in relation to VPuF and FSN, under statistical safety conditions. According to PCA, PC1 explained 90.243% of variance, and PC2 7.3695% of variance. Cluster analysis facilitated the grouping of the studied gladiolus varieties based on similarities in relation to the vegetative indices and floral quality parameters, in conditions of statistical safety (Coph.corr = 0.955).

Most important feature of the storage systems is to preserve the integrity of the grain for a given period with minimal loss in quality and quantity. The main objective of this study was to evaluate the effect of seed conditioning prior to storage process using infrared heating at the optimum radiation intensity of 882.67W/m2 and exposure time of 15 min and the ultraviolet radiation at radiation intensity of 3.538mW/cm2 and exposure time of 40 min on storability of cowpea seeds using different types of plastic hermetic bags in comparison with pp woven bags. The changes in cowpea seeds quality during storage of pre-treated cowpea seeds in terms of moisture content, protein content, total microbial count and insect detection were also determined. The results show that, the moisture content of seeds stored in pp woven bags increased in contrast with both types of studied hermetic bags, oxygen concentration for hermetic bags decreased during storage period and carbon dioxide increased unlike pp woven bag, The rate of seeds infection with microorganisms and weevils was lower for the samples stored in both types of hermetic bags and crude protein content of seeds stored in hermetic bags reduced at a very slight rate in comparison with that stored in woven bag.
