“…However, a weak relationship of grain Zn with panicle or culm indicates the presence of barriers for Zn allocation towards the grains ( Stomph et al, ). Minimum soil Zn at physiological maturity in SRI may be because of adsorption–desorption and dissolution–precipitation reactions of Zn with soil colloids and solution reducing its availability ( Gao et al, ; Xu et al, ).…”

Zinc (Zn) is an important micronutrient for rice (Oryza sativa L.) production and its deficiency has been observed in various production systems. High grain Zn concentration is equally important for high rice yield and human health. In this work, the effects of Zn fertilization on seedling growth, grain yield, grain Zn concentration, and their association with root traits were studied under alternate wetting and drying (AWD), aerobic rice (AR), system of rice intensification (SRI), and continuous flooding (CF). Zinc fertilization (15 kg ha−1) improved nursery seedlings chlorophyll and Zn concentrations, root length, and number of roots with highest values observed in CF. At harvesting, maximum plant height, panicle length, total and panicle bearing tillers, and kernel yield were found with Zn addition in AWD and CF rice systems. Mid season drainage provided at maximum tillering and Zn fertilization increased its concentration in leaves, culms, panicles, and grains under CF and AR at physiological maturity. Most of Zn applied was allocated into culms and panicles, nevertheless, a significant increase in grain Zn concentration was also observed in all production systems. Association of leaf Zn with grain Zn concentration was stronger than with culm and panicle Zn. The results indicate that Zn application after rice nursery transplanting is more important for grain Zn enrichment in all rice systems than for increase in grain yield in all systems except AWD where grain yield was also increased. More grain yield in CF and AWD as compared to SRI and AR can also be attributed to decreased spikelet sterility and to better Zn phyto‐availability in these rice systems at physiological maturity.

“…The possible reason of foliar nutrients effect on maize may be attributed because of efficient utilization and timely availability of potassium and zinc fertilizers as well as other nutrients (Witold et al, 2008;Farooqi et al, 2012;Abid et al, 2016). Potassium foliar spray to maize crop influenced its shift from vegetative to reproductive phase (Tabri and Akil, 2010;Xu et al, 2015). The early pollen shedding and silking increased grain yield of corn because grain filling period was longer which accelerated the better absorption of nutrients.…”

A field experiment was conducted for two years (2013 and 2014) to study the effect of foliar spray of potassium and zinc on maize crop under rainfed environment. Nine treatments were examined as: control, recommended rate of zinc (RRZn) to soil @ 15 kg Zn2SO4 ha ) were recorded under the combined foliar spray of potassium and zinc (FKS + FZS), followed by FKS + RRZn and RRK+ FZS. Greater net benefit and benefit cost ration were examined under all foliar sprays. Foliar spray of potassium and zinc is a fertilizer use efficient technique for increasing the maize yield attributes and net income under rainfed conditions.

“…Management practices such as air drying cycles are pertinent to soil moisture conditions, influencing the exchangeable fraction of heavy metals in the soil. Air drying enhanced Cd desorption in soil and the leachability of metals from dredged canal sediment increased during drying and oxidation processes [ 183 , 184 ]. Drying the soil in an oven resulted in notable rises in the concentrations of dissolved copper (Cu) and nickel (Ni).…”

One of the most concerning global environmental issues is the pollution of agricultural soils by heavy metals (HMs), especially cadmium, which not only affects human health through Cd-containing foods but also impacts the quality of rice. The soil’s nitrification and denitrification processes, coupled with the release of volatile organic compounds by plants, raise substantial concerns. In this review, we summarize the recent literature related to the deleterious effects of Cd on both soil processes related to the N cycle and rice quality, particularly aroma, in different water management practices. Under both continuous flooding (CF) and alternate wetting and drying (AWD) conditions, cadmium has been observed to reduce both the nitrification and denitrification processes. The adverse effects are more pronounced in alternate wetting and drying (AWD) as compared to continuous flooding (CF). Similarly, the alteration in rice aroma is more significant in AWD than in CF. The precise modulation of volatile organic compounds (VOCs) by Cd remains unclear based on the available literature. Nevertheless, HM accumulation is higher in AWD conditions compared to CF, leading to a detrimental impact on volatile organic compounds (VOCs). The literature concludes that AWD practices should be avoided in Cd-contaminated fields to decrease accumulation and maintain the quality of the rice. In the future, rhizospheric engineering and plant biotechnology can be used to decrease the transport of HMs from the soil to the plant’s edible parts.
