“…Boric acid is a soluble compound easily leached by rainfall; thus, boron deficiency commonly occurs in humid areas. Areas in southwestern China, northwestern India, Nepal, Japan, Bangladesh, and Brazil are considered as the most endangered by boron deficiency; however, the disorder may be expected in at least 80 countries in the world, including Zambia, Nigeria, Philippines, Thailand, Koreas, north European countries, and the Balkans [59,127,128]. In contrast to boron deficiency, soil boron toxicity is less abundant and occurs in arid and semi-arid areas.…”

Boron is an essential plant micronutrient taken up via the roots mostly in the form of boric acid. Its important role in plant metabolism involves the stabilization of molecules with cis-diol groups. The element is involved in the cell wall and membrane structure and functioning; therefore, it participates in numerous ion, metabolite, and hormone transport reactions. Boron has an extremely narrow range between deficiency and toxicity, and inadequate boron supply exhibits a detrimental effect on the yield of agricultural plants. The deficiency problem can be solved by fertilization, whereas soil boron toxicity can be ameliorated using various procedures; however, these approaches are costly and time-consuming, and they often show temporary effects. Plant species, as well as the genotypes within the species, dramatically differ in terms of boron requirements; thus, the available soil boron which is deficient for one crop may exhibit toxic effects on another. The widely documented intraspecies genetic variability regarding boron utilization efficiency and toxicity tolerance, together with the knowledge of the physiology and genetics of boron, should result in the development of efficient and tolerant varieties that may represent a long-term sustainable solution for the problem of inadequate or excess boron supply.

“…The diagnosis of Zn deficiency depends on plant tissue tests because soil tests for bioavailable Zn are generally unreliable ( Rayment and Lyons, 2010 ). Other macro- and micro- nutrients, temperature and the biological properties of the soil may also be involved in Zn bioavailability ( Fageria et al, 2012 ; Hafeez et al, 2013 ; Atique-ur-Rehman et al, 2014 ). Inherently low Zn status in soil is aggravated by submerged conditions ( Johnson-Beebout et al, 2009 ); consequently lowland rice is more susceptible to Zn deficiency than other cereals.…”

“…The aim of Zn biofortification of human food grains is to increase Zn concentration and its bioavailability in food, and this appears to be the most feasible, sustainable, and economical approach to address Zn deficiency in the human diet ( Zhao and McGrath, 2009 ; Salunke et al, 2011 ; Atique-ur-Rehman et al, 2014 ). Biofortification could be accomplished genetically through plant breeding and agronomically through Zn fertilization.…”

Though rice is the predominant source of energy and micronutrients for more than half of the world population, it does not provide enough zinc (Zn) to match human nutritional requirements. Moreover, climate change, particularly rising atmospheric carbon dioxide concentration, reduces the grain Zn concentration. Therefore, rice biofortification has been recognized as a key target to increase the grain Zn concentration to address global Zn malnutrition. Major bottlenecks for Zn biofortification in rice are identified as low Zn uptake, transport and loading into the grain; however, environmental and genetic contributions to grain Zn accumulation in rice have not been fully explored. In this review, we critically analyze the key genetic, physiological and environmental factors that determine Zn uptake, transport and utilization in rice. We also explore the genetic diversity of rice germplasm to develop new genetic tools for Zn biofortification. Lastly, we discuss the strategic use of Zn fertilizer for developing biofortified rice.

“…Data on plant height, spike length, total tillers, productive tillers, 1,000-grain weight, grains per spike, biological and grain yields of wheat were recorded following the standard procedures as detailed by . Likewise, data on plant height, panicle length, total tillers, productive tillers, kernels per panicle, 1,000-kernel weight, biological yield and grain yield of rice were recorded following the standard procedures as detailed by Rehman et al (2014). Harvest index in both crops was calculated as the ratio of grain yield to the biological yield and expressed in percentage.…”

The sustainability of rice–wheat cropping system (RWCS) is threatened by increasing labor, water, and energy crises in the region. Conservation RWCSs offers an ecofriendly alternate option. This study was aimed to evaluate the impact of sesbania brown manuring in direct‐seeded aerobic rice (DSAR) and of rice residue mulch in no‐tilled wheat (NTW) on soil health, weed dynamics and system productivity. The experiment was composed of five RWCS systems: (i) DSAR‐NTW; (ii) DSAR + sesbania brown manuring‐NTW; (iii) DSAR‐NTW + rice residue mulch; (iv) puddled transplanted flooded rice (PudTR)‐NTW; and (v) PudTR‐plow‐tilled wheat. Sesbania brown manuring in direct‐seeded rice decreased the weed density and dry biomass 41–56% and 62–75%, respectively, than the sole direct‐seeded rice crop. At rice harvest, better soil health, in terms of total nitrogen (N), soil organic carbon, soil microbial biomass carbon, and soil microbial biomass nitrogen, was noted with DSAR + sesbania brown manuring‐NTW. Rice residue mulch retention in NTW decreased weed density and dry weight by 60 and 69%, respectively, than those under NTW with no mulch. At wheat harvest, highest total N, soil organic carbon, and soil microbial biomass carbon were recorded with DSAR‐NTW + rice residue mulch, followed by DSAR + sesbania brown manuring‐NTW. Overall, NTW grown after DSAR + sesbania brown manuring produced more grain yield than PudTR‐NTW and PudTR‐plow‐tilled wheat systems. In conclusion, sesbania brown manuring in DSAR and residue mulch retention in NTW may be opted to improve soil properties, suppress weeds, and to harvest better grain yield and achieve higher system productivity in conservation RWCSs.
