“…On the other hand, considering global climate changes, salinization, desertification, natural erosion, and fertility reduction of soils, finding new areas to use as agricultural land is not an easy task to achieve [ 1 ]. Consequently, the improvement of plant resilience to adverse conditions and the improvement of crop production by using agrochemicals and organic fertilizers has largely been employed in the agronomic practices [ 2 , 3 ]. However, in the last century, the use of these products massively increased worldwide, resulting not only in a well-awaited intensification of food production, but also in serious environmental contaminations [ 2 , 4 ].…”

“…However, in the last century, the use of these products massively increased worldwide, resulting not only in a well-awaited intensification of food production, but also in serious environmental contaminations [ 2 , 4 ]. In addition, scientific evidence suggests that the use of agrochemicals may affect crop quality, in terms of sensorial, nutritional, and nutraceutical traits [ 2 , 3 , 4 ], and is also a potential risk for human health [ 5 , 6 ].…”

Plant biostimulants are under investigation as innovative products to improve plant production and fruit quality, without resulting in environmental and food contaminations. Here, the effects of the application of Expando, a biostimulant based on seaweed and yeast extracts, on plant productivity, fruit ripening times, and fruit quality of Solanum lycopersicum var. Micro-Tom were evaluated. After biostimulant treatment, a two-week reduction of ripening times and a concomitant enhancement of the production percentage during the earliest ripening times, in terms of both fruit yield (+110%) and size (+85%), were observed. Concerning fruit quality, proximate analysis showed that tomatoes treated with the biostimulant had better nutritional composition compared to untreated samples, since both the quality of unsatured fatty acids (C16:3ω3: +328%; C18:2ω6: −23%) and micronutrients essential for human health (Fe: +14%; Cu: +21%; Zn: +24%) were increased. From a nutraceutical point of view, despite strong changes in bioactive compound profile not being observed, an increase of the antioxidant properties was recorded in fruits harvested by plants treated with the biostimulant (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS): +38%; 2,2-diphenyl-1-picrylhydrazyl (DPPH): +11%). In conclusion, the biostimulant application was able to reduce the ripening times and fruit size, while slightly increasing nutritional and nutraceutical values, leading to more marketable tomato fruits.

“…Of this, yield losses caused by weeds are 10-12 per cent; those caused by pathogenic organisms are 18-20 per cent, and those caused by insects account for 8-10 per cent (Auernhammer, 2001). However, the demand of society to reduce the use of pesticides, both in terms of the quantities applied and the frequency of use, can be satisfi ed in a number of ways (Smith and Reynolds, 1966;Lambert and Lowenberg-DeBoer, 2002;Szentpétery et al, 2005).…”

“…Some herbicides are known to inhibit various processes such as nitrification, denitrification and nitrogen fixation. Based on previous research (Szentpétery et al, 2005;Jolánkai et al, 2006;Wágner and Nádasy, 2007) some herbicides influence nutrient uptake and yield quality. Dhima and Eleftherohorinos (2005) investigated the effect of nitrogen supply on interspecific competition between wild mustard (Sinapis arvensis L.) and wheat, barley and triticale.…”

Based on the results of earlier greenhouse tests, a field experiment was conducted to evaluate the effects of three different herbicide combinations (clomazone, flumioxazine and pendimethaline combined with bentazone) at increasing nitrogen levels on the nitrogen uptake of green pea and common lambsquarters ( Chenopodium album L.). Nitrogen was administered to the pea plants in the form of ammonium nitrate at increasing levels: 0, 100, 200 and 300 kg/ha. The experimental soil was loamy Ramann’s brown forest soil (Eutric Cambisol). Green peas were grown to green maturity and harvested according to standard agricultural practices. Following harvest, the fresh and dry weight of the pea and weed shoots were recorded. The nitrogen, phosphorus and potassium contents were determined from dried plant samples after digestion with concentrated sulphuric acid.The main results can be summarized as followsThe addition of nitrogen to the treatments considerably altered the growing potential of pea plants, especially at the early growth stage, where an increase in dry biomass of nearly 30% was observed. Yield biomass decreased in the nitrogen treatments. The nitrogen concentration, which increased in every treatment, was directly correlated to the addition of nitrogen fertilizer. Herbicides mainly influenced the vegetative growth of the plants. Pendimethalin and flumioxazin indirectly caused an increase in the dry biomass of the shoots by killing the surrounding weeds.
