“…In the latter year (2020), an excess amount of rain fell unexpectedly, which may have resulted in the leaching of nitrate and cations, reducing their uptake by the plants and growth, resulting in variations. This postulation is consistent with the results of Jabloun et al(2015), Abebe and Fayisa (2017), Wu et al (2020), andXia et al (2021) who suggested that large amounts of nitrate N remain below the root zone whose loss through leaching increases when rainfall is high. In the 2019 main cropping season, the amount of rain that fell amounted to ∼816 mm, which was neither low nor excessive but adequate for maize growth (Figure 1).…”

Maize (Zea mays L.) is an important food security crop in Ethiopia. However, low soil fertility and the use of haphazard nitrogen (N) fertilizer with little attention to the rate and timing of N application constrain productivity. Therefore, field experiments were conducted during the 2019 and 2020 cropping seasons to investigate the response of maize to different N application rates and timings. The treatments consisted of six N fertilizer rates (0, 23, 46, 69, 92, and 115 kg N ha −1 ) and four application timings (all at vegetative stages; one-half at sowing + one-half at vegetative stages; one-third at sowing + one-third at vegetative stages + one-third at tasseling; one-fourth at sowing + two-fourths at vegetative stages + one-fourth at tasseling). The experiments were a randomized block design in a factorial arrangement with three replications. The results of the study revealed that ears per plant, ear length, grains per row, grains per ear, stover, and grain yield were significantly (p ≤ .001) influenced by the interaction effects of N application rates and timings. The highest stover (9.99 t ha −1 ) and grain yield (9.41 t ha −1 ) were obtained from the application of 92 kg N ha −1 in three split applications of one-fourth at sowing, one-half at vegetative stages, and one-fourth at tasseling. Therefore, it is concluded that 92 kg N ha −1 in three split applications of one-fourth at sowing, two-fourths at vegetative stages, and one-fourth at tasseling was found to be the most economical in the study area.

“…Moreover, nitrate is the dominant form of N acquired by the majority of crops, which is soluble and highly mobile in soil, commonly lost by leaching and bacterial denitrification (Tilman et al., 2011). The typical example of leaching on ecosystems is the eutrophication of freshwater when high rates of nitrogen fertilizers are applied to agricultural systems (Giles, 2005; Tilman, 1999), which results in agricultural non‐point source pollution (Xia et al., 2020). Therefore, the need for sustainable agriculture in the coming decades requires a reduction in nitrogen fertilization and an improvement in nitrogen efficiency (Thilakarathna et al., 2012).…”

Lateral roots and root hairs are essential portions of cotton roots. However, the morphology and lifespan of cotton (Gossypium hirsutum L.) lateral roots and root hairs in response to nitrogen stress have remained unknown. Two cotton cultivars were assessed when no nitrogen and normal nitrogen (138 mg N·kg−1 soil) were added. The daily acquisitions of root phenotype information including the lateral root angle, lateral root density, lateral root diameter, lateral root lifespan, root hair length, root hair density, and root hair lifespan, were obtained in situ by a self‐designed platform of RhizoPots equipped with high‐resolution scanners. Nitrogen starvation significantly reduced the growth of shoots and roots, although there was less reduction of roots than shoots. Root hairs were the first organ to respond to nitrogen deficiency through morphological changes. The lateral root diameter and angle as well as the root hair lifespan decreased significantly under nitrogen stress. However, nitrogen deficiency dramatically increased the lateral root lifespan, root hair density and length. Our results demonstrate that low nitrogen can induce notable changes in lateral roots and root hairs, which may play a crucial role in the adjustment to nitrogen uptake, particularly in species that can adapt to low nitrogen availability.

“…However, peanut production in this area is limited by poor soil water and nutrient holding capacities, and water deficiency (Bai et al, 2014). Hence, the incorporation of plastic film mulching and supplemental irrigation have been studied as an extremely effective strategy with potential for decreasing soil evaporation, and enhancing crop growth, yield, and water use efficiency (Li and Gong, 2002;Ali et al, 2018;Xia et al, 2021a). However, the enhanced productivity under plastic mulches has been reported to result in lower soil fertility, which limit the subsequent crop productivity (Li et al, 2007;Steinmetz et al, 2016).…”

The effect of biochar application on photosynthetic traits and yield in peanut (Arachis hypogaea L.) is not well understood. A 2-year field experiment was conducted in Northwest Liaoning, China to evaluate the effect of biochar application [0, 10, 20, and 40 t ha−1 (B0, B10, B20, and B40)] on leaf gas exchange parameters, chlorophyll fluorescence parameters, and yield of peanut. B10 improved photochemical quenching at flowering and pod set and reduced non-photochemical quenching at pod set, relative to B0. B10 and B20 increased actual photochemical efficiency and decreased regulated energy dissipated at pod set, relative to B0. B10 significantly increased net photosynthetic rate, transpiration rate, stomatal conductance, and water use efficiency at flowering and pod set, relative to B0. Compared with B0, B10 significantly improved peanut yield (14.6 and 13.7%) and kernel yield (20.2 and 14.4%). Biochar application increased leaf nitrogen content. B10 and B20 significantly increased plant nitrogen accumulation, as compared to B0. The net photosynthetic rate of peanut leaves had a linear correlation with plant nitrogen accumulation and peanut yield. The application of 10 t ha−1 biochar produced the highest peanut yield by enhancing leaf photosynthetic capacity, and is thus a promising strategy for peanut production in Northwest Liaoning, China.
