A split-plot experiment arranged in a randomized complete blocks design with three replications was carried out in Safiabad Agricultural Research Center of Dezful in order to investigate the effects of foliar applications of ascorbic acid (AsA), salicylic acid (SA) and methanol (Me), under deficit irrigation conditions, in canola; there were 3 levels of irrigation as the main factor (irrigation after 70 mm evaporation from the pan as control, cessation of irrigation at the flowering stage and cessation of irrigation at the appearance of siliques) and 10 levels of foliar applications as sub-factor (100, 200 and 300 mg.l-1AsA; 100, 200 and 300 µM SA; 10, 20 and 30% (w/v) methanol; and foliar application of distilled water as control). Foliar applications were made during both budding and initiation of flowering stages. Results indicated that antioxidant enzymes showed different responses to deficit irrigation and foliar application treatments. Maximum catalase (CAT) and polyphenol oxidase (PPO) activities were observed under cessation of irrigation at flowering stage and foliar application of 300 µM SA, while ascorbate peroxidase (APX) reached its maximum activity under the same irrigation conditions and foliar application of 300 mg.l-1AsA. SA had more influence to increase in CAT and PPO activity under cessation of irrigation at flowering stage. The relative water content (RWC) was also decreased due to the drought stress caused by the cessation of irrigation. Foliar application of SA (100 μM) and Me (10% w/v) had more influence to maintain RWC compared to ascorbic acid under irrigation cessation at flowering stage.

The tomato fruit is rich in antioxidant compounds and has great nutritional and economic importance, annually promoting research on the nutritional and productive characteristics. The present study aimed to evaluate whether foliar application of commercial products based on growth regulators [auxin, cytokinin and gibberellin (Ax+CK+GA)], micronutrients [cobalt and molybdenum (Mi)] and mixtures of macro and micronutrients [nitrogen, boron, copper, molybdenum and zinc (Ma+Mi)], isolated and in combination, increase productivity and improve the post-harvest quality of tomato fruits (Predador F1). The experiment design used randomized blocks, with seven treatments and four repetitions, which were (T1) control; (T2) Ax+CK+GA; (T3) Ma+Mi; (T4) Mi; (T5) Ax+CK+GA + (Ma+Mi); (T6) Ax+CK+GA + Mi; and (T7) Ax+CK+GA + Mi + (Ma+Mi). The variables production, precocity, soluble solids content (SS), titratable acidity (TA), ratio (SS/TA), pH, total soluble sugars, ascorbic acid and weight loss were evaluated. The Ax+CK+GA application, isolated or in combination with Ma+Mi, promoted the precocity, and the use of isolated Ax+CK+GA and Mi improved the tomato plant productivity. The growth regulators, macro and micronutrients, isolated or in combination, increased the ascorbic acid content in the fruits.

The article presents data on the study of the effect of foliar water-soluble mineral fertilizer NOVATEK Solub K-Max 10-5-30 on the biochemical composition and commercial quality of apple fruits. A rise in vitamin C from the introduction of NOVATEK at a rate of 2.5 kg/ha indicates the effectiveness of this drug for optimizing the content of ascorbic acid in fruits. An increase in the content of monosaccharides and a decrease in disaccharides were found for all the studied rates of consumption of agrochemicals. The use of mineral fertilizer “Novatek Solub K-Max” contributed to increase the dry weight of fruits. The application of this mineral fertilizer is recommended for inclusion in the industry regulations for Apple cultivation as one of the elements of the technology.

Mulching Films

Scientists, extensions specialists, and growers are seeking sustainable agricultural practices that are able to cope with these objectives in order to ensure global food security and minimize environmental damage. The use of mulching films and plant biostimulants in agriculture seems to be a valid solution for tackling these rising concerns. A greenhouse experiment was conducted in order to elucidate the morpho-physiological and nutritive characteristics of lettuce (Lactuca sativa L.) in response to foliar application of a tropical plant extract (PE) biostimulant and the use of plastic mulches. Two biodegradable mulch treatments (Mater-Bi® 1 and Mater-Bi® 2) were compared to black polyethylene (LDPE) and bare soil. Biodegradable mulch film Mater-Bi® 1 produced a comparable marketable fresh yield to the commercial standard polyethylene (LDPE), whereas Mater-Bi® 2 exhibited the highest crop productivity. When averaged over biostimulant application, lettuce plants grown with biodegradable film Mater-Bi® 2 exhibited superior quality traits in terms of K, Ca, total ascorbic acid, and carotenoids content. The combination of film mulching (LDPE, Mater-Bi® 1 or Mater-Bi® 2) with the tropical plant extract biostimulant exhibited a positive and significant synergistic effect (+30%) on yield. The PE-biostimulant induced higher values of SPAD index and total chlorophyll content when compared to untreated greenhouse lettuce. The mineral content of leaf tissues was greater by 10% and 17% (for P and Ca, respectively) when compared to the untreated lettuce (no PE application). Nitrate content was significantly reduced by 23% in greenhouse lettuce plants receiving PE as compared to the untreated control. The positive effect of Mater-Bi® 2 film on the ascorbic acid content has also been highlighted when combined with the biostimulant application, where a major amplification of total ascorbic acid (+168%) was recorded in comparison to the untreated lettuce. Overall, our work can assist leafy vegetables growers in adopting good agricultural practices, such as biodegradable plastic mulches and vegetal-derived biostimulants, to improve the sustainability of greenhouse production.
