“…On the contrary, Asami et al [34] noted that management practices affected TPC of wheat. Simić et al, 2020 [35] tried to test the effect of tillage and cultivation year on maize and found that, phenolic content showed significant variations according to tillage system and growing season.…”

One of the proposed solutions to face climate change impact and to maintain food production sustainability is conservation agriculture. This study tries to determinate the effect of conventional tillage (CT) and no tillage (NT) on secondary metabolites such as total phenolics content (TPC), total flavonoids content (TFC) and antioxidants capacity (DPPH %) in relation to natural mycorrhization of durum wheat during the tillering stage for three cultivation years. The experiment was conducted in a referential farm (Krib, Siliana, North West Tunisia). The results showed that TPC, TFC and DPPH% were not influenced by tillage system (T). However, cultivation year (Y) had a significant effect on the studied parameters independently of tillage system. In addition, for the first cultivation year, tillage system (T) had significantly influenced the mycorrhization rate (MR%) and NT presented the highest mycorrhization rate (24%). DPPH% showed high significant positive correlations with MR% and TPC. For partial correlation based on Tillage system, high positive correlations were noted between DPPH%, MR% and TPC. Considering the partial correlation based on cultivation year, only a significant positive correlation between TPC and TFC was observed. In conclusion, durum wheat quality was not affected by tillage system and there are not reasons against no tillage adoption in this region for a sustainable wheat production.

Fertilizer inputs, crop yields, the composition of technological operations and intensity of treatment with different types of pesticides in both basic approaches were evaluated. A comprehensive comparison of impacts showed that all crops, except sugar beet, achieved better economic and emission parameters of production based on the evaluation of GHG production by using reduced tillage compared to ploughing. The total reduction of GHG emissions based on CO2eq on average of all crops per ton as a result of the technological processes was 6% using reduced tillage. The most significant CO2eq reductions were achieved for rye and oat (13%), and spring barley (8%). The reduction of crop yields ranges from about 1% (spring barley) to 4% (grain maize). Cost reduction per tone was in the range of 14% (rye) to 2% (silage maize). The energy gain was at reduced tillage improved at poppy (8%), rape (4%), oat (3%), rye (3%) and spring and winter barley (2%). From the evaluation of the number of chemical protections, a lower number of total protections was found at the no-till system for most crops. In most cases, there was no difference between ploughing and reduced tillage. There was an increase in specific nitrogen consumption per tonne of production in marginal areas, reduced tillage led to an increase in soil compaction.

“…Meta-analysis models are particularly useful for identifying patterns when data from multiple sources are combined and analyzed [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. Thus, for the comparison of water stress and N fertilization effects on grain quality components, random effects meta-analysis models were fit following the log response ratio (lnRR) approach [42].…”

Do Water and Nitrogen Management Practices Impact Grain Quality in Maize?

Concomitantly pursuing superior maize (Zeamays L.) productivity with grain quality is essential for food security. Therefore, this study provides a meta-analysis of 21 studies assembled from the scientific literature to tackle the effect of the two most limiting factors for maize production, water and nitrogen (N), and their impacts on grain quality composition, herein focused on protein, oil, and starch concentrations. Water stress levels resulted in erratic responses both in direction and magnitude on all the grain quality components, plausibly linked to a different duration, timing, and intensity of water stress treatments. Nitrogen fertilization more consistently affected the grain protein concentration, with a larger effect size for protein as fertilizer N levels increased (protein change of +14% for low, ≤70 kg N ha−1; +21% for medium, >70–150 kg N ha−1; and +24% for high, >150 kg N ha−1). Both starch and oil grain concentrations presented less variation to fertilizer N levels. The positive protein–oil correlation (r = 0.49) permitted to infer that although the oil concentration may reach a plateau (8%), further increases in protein are still possible. Augmented research on grain quality is warranted to sustain food production but with both high nutritional and energetic value for the global demand.
