Exogenous Ca priming can improve peanut photosynthetic carbon fixation and pod yield under early sowing scenarios in the field.

Harnessing cold-resilient and calcium-enriched peanut production technology are crucial for high-yielding peanut cultivation in high-latitude areas. However, there is limited field data about how exogenous calcium (Ca) application would improve peanut growth resilience during exposure to chilling stress at early sowing (ES). To help address this problem, a two-year field study was conducted to assess the effects of exogenous foliar Ca application on photosynthetic carbon fixation and pod yield in peanuts under different sowing scenarios.

Overfertilization reduces tomato yield under long-term continuous cropping system regulation of soil microbial community composition.

Long-term monoculture cropping and overfertilization degrade soil fertility, which reduces crop growth and promotes the development of soil-borne diseases. However, it remains unclear what the temporal effects of the above factors are on the tomato yield and microbial community structure. Thus, a greenhouse experiment with different amounts of fertilization [2,196 kg ha (control) and 6,588 kg ha (overfertilization) of inorganic fertilizers (NPK)] was carried out with the soils used previously for 1, 2, and 12 years under monoculture of tomato.

Supplementary Calcium Restores Peanut () Growth and Photosynthetic Capacity Under Low Nocturnal Temperature.

Peanut ( L.) is a globally important oil crop, which often experiences poor growth and seedling necrosis under low nocturnal temperatures (LNT). This study assessed the effects of supplementary calcium (Ca) and a calmodulin inhibitor on peanut growth and photosynthetic characteristics of plants exposed to LNT, followed by recovery at a higher temperature.
