Three tests were conducted with the « Apollo » variety of Mediplant company during the dry season of 2016-2017 in the horticultural domain of « Le Relais - Sénégal » in Yendane-Terokh in order to optimize leaf and stem production of sweet wormwood (Artemisia annua L.). All tests were conducted under sprinkle irrigation; allowing a 50 % gain of yield harvest in comparison with the 2016 yield under drip irrigation. The first test aimed to determine the most suitable plant density with two cuts (most efficient cutting frequency identified in 2016). An additional intermediary cut increased production by 25 % regarding the single cut production, while remaining at an interesting proportion of leaves and stems. The 20 000 plants/ha density distinguished itself from the others by a better production per hectare and by the lowest cost price. Moreover, this density with the spatial system of 1 m x 0,5 m, induced a decrease of Rhizoctonia genus pathogenic fungus which appeared during the trial. The second test aimed to determine the best mineral fertilisation formula and dose adapted to local conditions by testing the effect nitrogen, potassium and phosphorus substraction from the complete fertilizer. Results put in evidence a potassium deficiency in the farm soil and a lack of synergic effect linked to the presence of sulphur in some fertilizer applied. Nitrogen remains the decisive element for plant growth and yield per hectare. An input greater than 29 kg N/ha improved yield and explains the interest for the actual optimal mineral treatment consisting in 47,3 kg N/ha, 4,2 kg P2O5/ha et 8,3 kg K2O/ha. No significant differences were observed between organic treatments and the mineral control fertilizer. The third test aimed to determine the most adapted organic fertilization taking into account its cost and availability in the area. No significant differences were observed in terms of yield between the 6 modalities of poultry or cow-horse manure based organic fertilizer. The cost-effective solution was to input 3 handfuls of cow-horse compost 30, 60 and 90 days after transplantation. From a practical point of view, the 20 000 plant/ha density option, under sprinkler irrigation, with the additional intermediary cut approximately 3 months after transplantation and the input of 47,3 kg N/ha, 4,2 kg P2O5/ha et 8,3 kg K2O/ha was identified as the best crop management technique for the moment being for sweet wormwood production in dry season (transplantation in December – final harvest in the end of May). This technological itinerary enabled a raw material yield for infusion and capsule production of about 8 tons/ha, and a cost price around 0,70 EUR (460 FCFA) per kg with a 50%-50% mix ratio of dried leaves and stems.

Modern agriculture needs to have high production efficiency combined with a high quality of obtained products. This applies to both crop and livestock production. To meet these requirements, advanced methods of data analysis are more and more frequently used, including those derived from artificial intelligence methods. Artificial neural networks (ANNs) are one of the most popular tools of this kind. They are widely used in solving various classification and prediction tasks, for some time also in the broadly defined field of agriculture. They can form part of precision farming and decision support systems. Artificial neural networks can replace the classical methods of modelling many issues, and are one of the main alternatives to classical mathematical models. The spectrum of applications of artificial neural networks is very wide. For a long time now, researchers from all over the world have been using these tools to support agricultural production, making it more efficient and providing the highest-quality products possible.

Herbaceous field crops include several hundred plant species worldly widespread for different end-uses, from food to no-food applications. Among them are included cereals, grain legumes, sugar beet, potato, cotton, tobacco, sunflower, safflower, rape, flax, soybean, alfalfa, clover spp. and other fodder crops, but only 15–20 species play a relevant role for the worldly global economy. Nowadays, to meet the food demand of the ever-increasing world population in a scenario of decreased arable lands, the development of holistic agricultural management approaches to boost contemporaneously yield and quality of herbaceous field crops is essential. Accordingly, this book represents an up-to-date collection of the current understanding of the impact of several agricultural management factors (i.e., genetic selection, planting density and arrangement, fertilization, irrigation, weed control and harvest time) on the yield and qualitative performances of 11 field crops (wheat, cardoon, potato, clary sage, basil, sugarcane, canola, cotton, tomato, lettuce and hemp). On the whole, the topics covered in this book will ensure students and academic readers, such as plant physiologists, environmental scientists, biotechnologists, botanists, soil chemists and agronomists, to get the information about the recent research advances on the eco-sustainable management cultivation of herbaceous field crops, with a particular focus on varietal development, soil nutrient and water management, weed control, etc.
