This Feature Article tracks 100 years of soil disinfestation: from the goal of eradicating soilborne pathogens and pests to much milder approaches, aimed at establishing a healthier soil, by favoring or enhancing the beneficial soil microflora and introducing biological control agents. The restrictions on use of many chemical fumigants is favoring the adoption of nonchemical strategies, from soilless cultivation to the use of physical or biological control measures, with more focus on maintaining soil microbial diversity, thus enhancing soil and plant health. Such approached are described and discussed, with special focus on their integrated use.

ABSTRACT: Soilless cultivation of strawberry is in expansion in Brazil due to factors like the reduction of phytosanitary problems and the possibility of extending the crop period, as well as the ergonometric facility for management of the culture. However, black fungus gnats (Sciaridae, Diptera) are ubiquitous pests in the greenhouse production system, causing direct and indirect damage to plants. ThIS study evaluated the occurrence of black fungus gnats species in semi-hydroponic cultivation of strawberry and to identify the species, as well as to describe the symptoms in infested plants. The research was developed in commercial productions of strawberry, in five municipalities (Arroio do Padre, Canguçu, Capão do Leão, Pelotas and Turuçu) during July to December 2017, where adult samples were collected twice a month, with petri dish traps containing water and neutral detergent placed inside the greenhouses between the plants. A total of 2030 adult gnats belonging to two species were collected. Bradysia aff. impatiens, accounted with 90.79% of the total, and Bradysia aff. ocellaris, accounted with 9.21%. In order to assist the correct determination of species, males of both species were identified and illustrated. With respect to the symptoms observed during the research, it was possible to verify since the wilted crown of plants to the death of plants, which were confirmed by the presence of larvae in the root system. As the occurrence of these insects is recent in strawberry, there is no pesticide registered in Brazil, so management strategies (cultural, physical, and sanitary) also are discussed.

As the populace increments and characteristic assets decline, the capacity to serve humankind with an adequate measure of nourishment turns out to be progressively troublesome. The measure of rural land diminishes relatively to the expanding populace, along these lines the measure of nourishment delivered will diminish fundamentally, and will be lacking to serve the developing populace. The universal strategies for cultivating won't do the trick sooner. Thus, using modern technology and resources, a method of efficient farming must be introduced and employed in the agricultural field. This report introduces a method of efficient farming using hydroponics. The system is automated and uses sensor data to make decisions to benefit the crops being grown. The system runs on Raspberry PI and Arduino, and utilizes OpenCV. With our system we hope to solve the potential food crisis and give everyone access to fresh produce all year round.

Rockmelon (Cucumis melo L.) belongs to the Cucurbitaceae family, which can adapt to various soil and climate areas, especially in Malaysia. The production of rockmelon in Malaysia has highly declined, and for this reason, farmers have opted to use the concept of soilless cultivation due to it benefits accrued from soilless media such as cocopeat, perlite, and burnt rice husk. The study was carried out to determine the effect of different growing media on the physical morphology of rockmelon seedlings. This experiment was set up using RCBD arrangements with four replications. Different growing media used were: (i) 100% Black Soil (BS), (ii) 75% cocopeat + 15% burnt rice husk + 10% perlite (M1) and (iii) 75% cocopeat + 20% burnt rice husk + 5% perlite (M2). The parameters measured were plant height, number of leaves and total leaves area, and stem girth. The data were collected within two weeks after transplanting. The parameters measured were subjected to ANOVA and LSD was applied to compare means. In this study, rockmelon seedlings treated on BS showed significantly (P<0.001) the highest plant height, number of leaves per plant, and total leaves area and stem girth. Seedlings on soilless M1, however, grew in slightly good conditions, as it showed the insignificantly higher values on morphological parameters measured. Thus, BS is still suitable for better use of media for 15 days old rockmelon seedlings (after transplanting). It gives the optimum conditions for adapting seedlings to the new exposure environment.

Barattiere and Carosello are typical melon (Cucumis melo L.) landraces of Puglia’s (Southern Italy) biodiversity. Their unripe fruits are locally consumed as an alternative to cucumbers (C. sativus L.) and are appreciated for their qualitative profile. Nevertheless, they are underutilized crops. For the high variability and confusing denominations, a morphological characterization is essential to discriminate and valorise landraces; additionally, it is fundamental to implement the agronomic technique to allow the cultivation outside the natural growth period (summer) by soilless cultivation. Two genotypes of Barattiere (‘Allungato’ and ‘Tondo’), two of Carosello (‘Scopatizzo’ and ‘Tomentoso’ (CAT)) and two of cucumber (‘Baby Star’ and ‘Modan’ hybrids) were vertically grown in the winter-spring period in a rockwool soilless system in a glasshouse with supplemental light. Landraces were characterized by morpho-physiological descriptors of melon; fruit biometrics and colour were analysed for all genotypes; productive parameters, leaf fluorescence, and chlorophyll content were measured. Genotypes varied in seeds, stem, leaf, fruit traits and they were andromonoecious; Carosello flowered earlier and produced more than Barattiere; CAT fruits were hairy and elongate, while other genotypes tended to rounder and glabrous fruits. Although landraces grew slower than cucumbers, both produced marketable fruits and the production of Carosello was comparable to cucumbers. In conclusion, Barattiere and Carosello have a productive potential and one vertically trained stem in a soilless system is appropriate for their extra-seasonal production.
