Citrus Production

Water and nitrogen (N) are important inputs for most crop production. The main objectives of nitrogen best management practices (NBMP) are to improve N and water management to maximize the uptake efficiency and minimize the leaching losses. This require a complete understanding of fate of N and water mass balance within and below the root zone of the crop in question. The fate of nitrogen applied for citrus production in sandy soils (>95% sand) was simulated using a mathematical model LEACHM (Leaching Estimation And Chemistry Model). Nitrogen removal in harvested fruits and storage in the tree accounted the major portion of the applied N. Nitrogen volatilization mainly as ammonia and N leaching below the root zone were the next two major components of the N mass balance. A proper irrigation scheduling based on continuous monitoring of the soil water content in the rooting was used as a part of the NBMP. More than 50% of the total annual leached water below the root zone was predicted to occur in the the rainy season. Since this would contribute to nitrate leaching, it is recomended to avoid N application during the rainy season.

In the U.S. Virgin Islands (USVI), herbs and spices are in great demand, mainly for culinary purposes. These crops include thyme, basil, oregano, parsley, chives, fennel, rosemary and marjoram. Based on estimated total marketable yield of 25 growers in 1993, 10,264 kg of fresh culinary herbs were produced in USVI. During the same period, 21,207 kg of various herbs were imported to the USVI. These data clearly show that local demand for herbs exceeds domestic production. Constraints which limit increased production in USVI include small farm size, limited water resources, absence of mechanization and limited information on crop management practices. Many herb growers use traditional farming practices and for the most part avoid modern approaches to cultivation. Appropriate cultural and management practices (e.g. drip irrigation, mulching, fertilizer, etc.) could potentially boost production and increase overall efficiency despite the reality of small farm acreages. This paper will describe the current status of herb production in the USVI, constraints to production and proposed solutions to improve its economic prospect.

Survey were undertaken in five zones of Oromiya and Amhara regional states, Ethiopia from February to March 2018 to investigate farmers’ status, knowledge, major chickpea production constraints and insect pest management practices of chickpea. The survey involved 293 randomly taken farmers, who are interviewed using a semi-structured questionnaire. Chickpea insect pests were considered as the main, among production constraints of chickpea by most of the interviewed farmers in Ethiopia. The majority of the farmers’ responded that Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is the most prevalent insect pests of chickpea under field condition and Callosobruchus chinensis (L.) (Coleoptera: Bruchidae) in storage. Development Agents (DAs) were the top pest advisory service providers in the current study. A conventional insecticide (namely; Lambda-cyhalotrin and Dimethoate) for the control of H. armigera was the most commonly used pest management methods. Moreover, Two times insecticide applications per cropping season were the most frequent, deployed by most of the interviewed farmers followed by cultural pest management practices. Use of biological control and resistant chickpea varieties against major insect pests were low to negligible in the current survey study in the area. The majority of the farmers began control decision when H. armigera larval stages were smaller and they did not consider larval number per chickpea plant for the decision. These results will be used to formulate future effective and sustainable integrated pest management (IPM) in chickpea for Ethiopian farmers emphasizing ecologically and economically-based approaches.

A survey was conducted to appraise the guava farming in Nepal with respect to the orchard management practices, cultivar status and major production constraints during July- December 2001. Guava plantation was extensively distributed throughout terai, inner terai and mid hill districts ranging in altitude from 115 masl to 1600 masl. Indian varieties dominated the guava plantation in Nepal although mix population of both improved and local cultivars was reported in majority of orchards. Preponderance of seedling origin guava plantation was noticed. The management practices were poor. Over 80% of the orchards received neither FYM nor chemical fertilizer. Similarly, more than 90% of the orchards were under rainfed condition. The peak period of flowering was reported during April/May followed by Feb/March that may extend up to June/July. As a consequence, the fruit availability period is mainly restricted to four months, i.e. July/ August to Oct/Nov. Most of the growers pointed out guava wilt as the main biotic constraint in guava production. The outcomes indicted the urgent need to adopt the effective control measures against the guava wilt malady to flourish guava enterprise in Nepal. Furthermore, off-season production of guava fruit has the great potential in Nepalese market. Key words: cultivar, guava wilt, orchard, Psidium guajava J. Inst. Agric. Anim. Sci. 26:127-133 (2005)

SUMMARYDespite tremendous efforts made in agricultural sectors in sub-Saharan Africa in the last two decades, fruits production and consumption to reduce malnutrition and chronic diseases remain low and have received less attention. Moreover, our knowledge of the current production situation and options for improvement are still limited. In this study, we investigated citrus farming systems and production bottlenecks to identify leverage points for intensification of smallholder citrus farming systems in Benin. We provided a typology of citrus orchards based on 17 quantitative and qualitative variables using Factor Analysis of Mixed Data combined with Hierarchical Cluster Analysis. The typology revealed four categories of citrus farms based on biophysical resources, socioeconomic resources and system management practices. Categories 1 and 2 included farms characterised by less diversified cropping systems with non-recommended management practices. Orchard categories 3 and 4 included farms with high varietal diversity and improved management practices. However, farmers of category 4 neglected staking and digging practices. The inadequate farming practices explained some of the production bottlenecks, which were orchard-type dependent. We discussed the implications of our findings and suggested a number of policy and strategic decisions as well as research and development actions for improving citrus production in Benin.
