Abstract Yellow River Delta’s arable land had great potential for grain production if reasonable agronomic measures were taken. To date, the question of whether and how biochar (C) phosphorus (P) addition jointly regulates maize in this area remains unclear. Consequently, a two-year (2021–2022, with contrasting climatic conditions) field experiment including three intensities ((0 (C0), 5000 (C1), 10000 (C2) kg ha− 1 )), fertilization levels (0 (P0), 100 (P1), 200 (P2) P2O5 ), their combinations was conducted Wudi, Shandong province, China.

Adjusting the planting date is an inexpensive and effective method to mitigate possible effects of water stress. A 2-year field study was conducted investigate dates on biochemical physiological characteristics yield safflower (Carthamus tinctorius L.) under stress in 2018 2019 growing seasons. The treatments consisted three (December 6 26 January 15), irrigation regimes (normal irrigation, cut-off at flowering seed filling) two cultivars (Goldasht Isfahan). During period, pigment content, enzyme activity, canopy temperature, assimilate remobilization, use efficiency (WUE) were measured. Planting regime had a significant effect all parameters, with most differences observed when during filling, resulting reductions up 31% Goldasht. Irrespective date, reduced total chlorophyll by 7.5-28.4% increased temperature. When cut off, relative content (RWC) Goldasht 10.8-11.7% higher than that Isfahan December 26. Although stage planted lowest value. Chlorophyll a, carotenoid catalase peroxidase activities generally highest 26, especially In addition, dry matter remobilization first year due average temperatures evaporation. Goldasht, WUE end normal irrigation. Oil also late December. positive relationship between chlorophyll, RWC, number seeds per capitulum, WUE. Overall, optimal stress, for which resulted both years.
