This study was conducted in the mid-Northern Ugandan districts of Nwoya, Gulu, Lira, Apach and Oyam to characterise the coffee-banana agroforestry systems. Thirty fields with coffee-banana agroforestry systems were selected and the level of field and crop management determined. Additionally, five coffee and banana plants were randomly selected and assessed for pests and diseases. All fields had Robusta coffee type whereas cooking bananas were the dominant clone (45%). Field management was limited. More than 80% of the fields had no bands, trenches or cover-crops. Most of the fields were lowly weeded (46.7%) and mulched (60%). Intercropping was low with 20% having maize or cassava. Similarly, most fields were lowly inter-planted with trees (40%) with only 28 tree/shrub species and dominated by fruit trees; namely oranges (70%), mangoes (63.3%) and pawpaw (56.7%) of the total number of tree species observed in the systems. Generally, 40% of coffee fields had not been de-suckered, pruned or changed cycle. However, at least 35% of the coffee fields were highly pruned and their cycle changed. For bananas, more than 70% of the fields were not de-suckered, propped or their corms removed, but 63% of them had been de-leafed and de-budded at a low to moderate level. Leaf skeletonisers and coffee leaf rust were the most observed pest (77.3%) and disease (15.3%) respectively. Pest damage was limited in bananas, though black Sigatoka was the commonest disease observed (56%). It is concluded that the region has embraced the systems but there is need for farmers to be provided with the right species of coffee, banana and trees.Keywords: Agroforestry-systems, cooking-bananas, Robusta-coffee.

The Impact

The objective of this study is to evaluate the importance of plant diversity in insect management in agroecosystems.The conventional management of agroecosystems is based on monoculture, with exploitation of plant genotypes susceptible to pests and diseases, with intense use of agrochemicals and soil mechanization. The impact on agroecosystem biodiversity by intensifying agronomic practices results in losses of important ecological functions: decomposition, nutrient cycling, predation and parasitism. The potential of plant diversity in the sustainability of agroecosystems is recommended through practices such as intercropping, agroforestry systems, management of cover crops, spontaneous herbs and the use of plants attractive to natural enemies and as pest traps. Farm planning should take into account some level of plant diversification to avoid pest insect outbreaks. Thus, it will be possible to reduce pesticides in conventional system, and reduce the number of interventions with alternative substances in farm in agroecological systems.

The insect problem is accentuated in intensive rice cropping where the insects occur throughout the year in overlapping generations. Over 800 insect species damaging rice in one way or another, although the majority of them do very little damage. In India, about a dozen of insect species are of major importance but the economic damage caused by these species varies greatly from field to field and from year to year. Insect pests cause about 10-15 per cent yield losses. Farmers lose an estimated average of 37% of their rice crop to insect pests and diseases every year. This review focuses on precision farming tools being used in rice pest and diseases management viz., forecasting model for real-time pest-advisory services, hyper-spectral remote sensing in pest damage assessment, computer-based decision support system, disruptive technologies (mobile apps).

In the tropics, products and services provided by the traditional agroforestry systems (TAS) support the basic needs and promote the livelihood of millions of rural people. However, the outcomes and mitigation of TAS, in particular, the social and environmental issues are not systematically addressed. Thus, the objective of the study was to assess the economic, social and environmental outcomes of two important TAS in Bangladesh. This study reports results on prospective analyses using the Date palm and Jackfruit-based TAS practiced in the Jashore and Mymensingh districts of Bangladesh. The results revealed that the TAS enhanced farm productivity and the benefit–cost ratio of both systems were much higher than the general agricultural practices in Bangladesh. The TAS also improved resilience of rural farmers through more efficient water utilization, enhancing soil fertility, improving microclimate, controlling pests and diseases, and diversifying products. At the same time, the farmers’ problems were neglected due to the absence of farmers’ platforms, and also tradeoffs may arise; thus, the social aspects of the TAS farmers had not developed equally. Therefore, the study would recommend minimizing the tradeoffs through enhancing the conservation strategies at farmers’ levels to make the TAS more viable and sustainable land-use practices.

Rapid expansion of unsustainable farming practices in upland areas of Southeast Asia threatens food security and the environment. This study assessed alternative agroforestry systems for sustainable land management and livelihood improvement in northwest Vietnam. The performance of fruit tree-based agroforestry was compared with that of sole cropping, and farmers’ perspectives on agroforestry were documented. After seven years, longan (Dimocarpus longan Lour.)-maize-forage grass and son tra (Docynia indica (Wall.) Decne)-forage grass systems had generated 2.4- and 3.5-fold higher average annual income than sole maize and sole son tra, respectively. Sole longan gave no net profit, due to high investment costs. After some years, competition developed between the crop, grass, and tree components, e.g., for nitrogen, and the farmers interviewed reported a need to adapt management practices to optimise spacing and pruning. They also reported that agroforestry enhanced ecosystem services by controlling surface runoff and erosion, increasing soil fertility and improving resilience to extreme weather. Thus, agroforestry practices with fruit trees can be more profitable than sole-crop cultivation within a few years. Integration of seasonal and fast-growing perennial plants (e.g., grass) is essential to ensure quick returns. Wider adoption needs initial incentives or loans, knowledge exchange, and market links.

All farmers and growers have at some time faced the decision of whether to control a pest in their crop. In order to make the correct decision the farmer needs access to, and an understanding of, sufficient information relevant to such pest problems. Decision support systems are able to help farmers make these difficult decisions by providing information in an easily understandable and quickly accessed form. The increasing use of computers by farmers for record-keeping and business management is putting the hardware necessary for the implementation of these systems onto more and more farms. The scarcity of expert advice, increasingly complex decisions and reduced economic margins all increase the importance of making the right pest management decision at the right time. It is against this background that decision support systems have an important role to play in the fight against losses caused by pests and diseases.

Neem (Azadirachta indica A. Juss) is a member of Meliaceae family, a fast-growing tropical evergreen plant whose products were found effective against economically important insect pests and diseases. All parts of this plant particularly leaf, bark, and root extracts have the biopesticidal activities. Azadirachtin, a biopesticide obtained from neem extract, can be used for con-trolling various insect pests in agriculture. It acts on insects by repelling them, by inhibiting feeding, and by disrupting their growth, and reproduction. Neem-based formulations do not usually kill insects directly, but they can alter their behavior in significant ways to reduce pest damage to crops and reduce their reproductive potential. The neem is considered as an eas-ily accessible, eco-friendly, biodegradable, cheap, and non-toxic biopesticide which control the target pests. Thus, this re-view highlighted the extract, byproducts and roles of neem that can be used as potential biopesticide in agriculture.

Abstract Growing fruit trees is a long term financial commitment and establishing an orchard is an expensive enterprise. Selecting the right orchard site is arguably the most important decision that a sweet cherry grower will make and it will affect all other managerial decisions related to the orchard. Choosing the wrong site can affect both fruit yield and quality, and ultimately the financial viability of the operation. On the other hand, choosing a good site will reduce expenses and increase profits. Properly evaluating a prospective orchard location, determining available resources and establishing the orchard takes careful planning. This chapter focuses on important factors in planning a new cherry orchard, including economics and site evaluation (climatic conditions, topography, soil characteristics, soil analysis, water availability and quality, access to key auxilliary facilities, and environmental impact).
