Germination tests on water agar demonstrated the priming effectiveness for wheat, but not for tomato, as the analysed parameters were not positively affected. The pFE was used also in combination with the known biocontrol agent <i>Trichoderma harzianum</i> T22 (T22), demonstrating that they could work together to obtain a good growth promotion and protective effect in wheat. Indeed, the priming with pFE significantly reduced the disease incidence of almost 60% or 80%, compared to the infected control, if used alone or combined with T22, respectively. The ability of frass extract to control <i>F. sporotrichioides</i> in wheat was attributed to both enzymatic and non-enzymatic responses, due to observed differences in total phenolic content (TPC) and superoxide dismutase activity (SOD) in seedlings derived from treated seeds, compared to untreated control.

The chroma value, flavonoid content, phenolic content, vitamin C content, and antioxidant activity of cherry tomatoes are the main quality parameters investigated in this study, along with the effects of cultivars, growing climates, and watering regimens.

Cultivar and growing climate significantly affected flavonoid content, with Fortesa and rain shelter environments exhibiting the most significant values. Cultivar and growing climate significantly impacted vitamin C content; ruby and greenhouse conditions produced the maximum amounts. Across all parameters, there were significant variances in antioxidant activity; Ruby showed the maximum activity, and the rain shelter provided the ideal growing environment. The market analysis conducted for the study reveals that higher-quality cherry tomatoes are famous among upscale and health-conscious consumers due to their high flavonoid and phenolic content, brilliant chroma value, and considerable antioxidant activity.

Biostimulants may boost vegetative growth, enhancing plant tolerance to biotic and abiotic stress. The tomato (<i>Solanum lycopersicum</i> L.) is sensitive to drought stress, particularly during fruit setting and fruit development stages. In Italy, long-storage tomato genotypes characterised by drought resistance were selected. In this 2-year study, the foliar application of different biostimulants (betaine, seaweed extracts, vegetal protein hydrolysate and animal protein hydrolysate) was evaluated to determine effects on yield and quality of a local tomato landrace (Pizzutello) cultivated in Sicily without irrigation. The highest dry matter (9.9%) and solid soluble content (6.9° Brix) were observed in plants treated with betaine. Plants treated with <i>A. nodosum</i> or animal protein hydrolysate showed the highest potassium concentrations, whereas those supplied with vegetal protein hydrolysate had the highest calcium concentrations. Tomato treated with betaine were found to have the highest nitrate concentrations. The highest marketable yield (13.8 t ha⁻¹) was recorded in plants treated with vegetal protein hydrolysate, with an increase of 17.4% compared to the control plants. The highest unmarketable yield was observed in control plants and in those treated with betaine (1.1 t ha^-1). In conclusion, we can say that each biostimulant had a different effect on the different parameters analysed. Overall, the application of biostimulants has improved tomato growth, productivity and quality in limited water conditions. Our results highlight the potential of biostimulant applications to optimise both the yield and fruit quality of renowned local varieties.

Furthermore, adopting net-zero farming practices can help achieve carbon neutrality in agriculture while significantly reducing GHG emissions.

Therefore, this study estimates eCH4 emissions from pasture-based peri-urban dairy farms across four different animal categories during dry and wet seasons. Six herds were selected for field measurements; one representative animal was selected per category from each herd and its body weight estimated.
