Special Issue Information

Dear Colleagues,

Sustainability and productivity in agriculture cannot be separated. The increase in agricultural productivity in the context of environmental and economic sustainability is the result of the improvement of the entire production system: soil health management, plant improvement of output performance, optimization of crop and water management, correct approach to the protection from phytophagous organisms, plant diseases, and weeds. Goals such as the protection and enhancement of primary resources and biodiversity, land management and protection from natural and man-made risks can only be achieved through a systemic approach. Agroecological crop protection (ACP) is based on a qualitative but explicit model of the dynamics of pest and natural enemy populations at the scale of a section of the landscape adjoining the plot. ACP is therefore compatible with integrated pest management. Indeed, these two approaches may be seen as complementary because they are not on the same plane: the term ACP refers to the knowledge to be mobilized, and IPM to the operations to be carried out and their combination within technical itineraries. If it meets ACP criteria, IPM takes the form of its most demanding version, that of the use of chemical pesticides strictly as a last resort.

This Special Issue aims to collect scientific contributions resulting from multi-disciplinary and trans-disciplinary approaches on the theme of the progressive redesign of food and non-food cropping systems. We expect contributions dealing with experiences linking the research of innovative strategies for phytosanitary protection from phytophagous, pathogens, weeds with agroecological management needs (tillage management, soil fertilization, crop irrigation, crop choice, crop spatial distribution, and temporal succession) capable of building soil and plant health, to supporting the production of crop systems while reducing reliance on external inputs.

Climate change poses significant challenges for countries in Northern Africa such as Morocco. Smallholder farmers are especially vulnerable to climate change because they experience several challenges in the adoption of climate-resilient practices. The sustainable and well-managed cultivation of the cactus pear (Opuntia ficus-indica) could contribute to conservation agriculture (CA) in dry climates threatened by climate change. Due to its high-water-use efficiency and ability to withstand extremely dry conditions, the cactus pear is increasingly being recognised as a more sustainable alternative to traditional livestock foraging in dryland areas. Compared to many other common crops and fodder, the cactus pear is easy to establish, maintain, and has a wealth of uses. Two innovative cultivation techniques are being developed: (1) the use of mixed inoculum formulations containing AMF (Arbuscular Mycorrhizal Fungi) and PGPB (Plant Growth-Promoting Bacteria) in the soil; and (2) intercropping between perennial (cactus pear) and short-term species (field crops). We propose to identify factors that could facilitate farmers’ innovation adoption. We conducted face-to-face interviews with 24 smallholder cactus pear farmers in Morocco. We concluded that farmers do not yet have a comprehensive understanding of the principles of the innovations. The main aim of farmers was to increase production and income. Farmers, in general, pay little attention to the environment. The recommendations that are given in relation to these issues are that training and social networks are essential in innovation transfer, adoption needs to be facilitated by providing resources, an innovation transfer needs to be adapted to the current and future needs of farmers, and we need patience so that farmers can slowly learn the innovations.

The brown wheat mite, Petrobia tritici, poses a significant threat to wheat fields. While fertilizers can increase crop productivity, imbalanced application may exacerbate plant susceptibility to pests. This study aimed to evaluate the impact of various NPK fertilization programs on P. tritici infestations over two consecutive cropping seasons. The results revealed significant differences in mite infestation among the treatment groups (p < 0.001). The lowest populations (1.1 and 3.0 mites/leaf) were observed in the treatments sprayed with phosphoric acid (at 0.75 and 1.00 cm/L), where the infestation appeared approximately 120 days after sowing; in contrast, it appeared early at 75 days in the other treatments. Conversely, treatments lacking potassium fertilizer presented the greatest degree of mite injury levels (49.5–57.7 mites/leaf). Although these treatments provided moderate leaf nutrition and crop yield, the highest nutritional content and total yield (10.49 and 9.71 1 t/ha for the two years) were observed in the treatment that received 224:70:100 kg fad−1 commercial fertilizers (=178:25:114 kg ha−1 NPK units) as soil fertilization, which was followed by the treatment with a foliar application of phosphoric acid (1.00 cm/L) with a total yield of 9.34 and 8.53 1 t/ha for the two years. In this treatment, the P. tritici density was moderately high at 9.40 and 6.32 mites/leaf over the two years, respectively. The consistency of P. tritici density and total yield ranking across both years indicated reliable estimates of the impact of fertilization. This study suggests that potassium sulfate application is crucial for reducing P. tritici density and that foliar phosphoric acid application instead of soil application reduces the number of P. tritici and delays its occurrence.
