“…The non-significant change in grain fill duration found in this study shows the robust genetic composition for photoperiod and vernalization in facultative wheat cultivars grown in Pakistan. Arafat [43] also reported no change in grain filling duration as a result of zinc foliar spray, as grain fill duration depends upon the exposure of the crop to sunlight (photoperiod) and temperature, which were experienced by all the plots uniformly. Our significant results regarding the number of grains per spike were in correlation with the discoveries of Aslam and Zeidan [44,45], who also found an increase in the number of grains per spike with foliar zinc treatment.…”

Agronomic biofortification could possibly be a promising strategy to overcome zinc (Zn) deficiency in wheat; however, the cultivar’s response to foliar applications is enigmatic when it comes to the relative efficiency of Zn absorption and accumulation. To decipher that enigmatic response, this study was designed with the objectives (i) to track the amount of Zn absorbed through leaves after foliar application, (ii) to calculate the amount of the absorbed Zn actually translocated and stored in the grains, and (iii) to calculate the relative efficiency of the high yielding cultivars in terms of their Zn absorption and translocation. The results reveal that 0.90% of the zinc sprayed was absorbed through leaves, and 43% of the absorbed Zn was translocated to the grains. The cultivars significantly varied for their Zn absorption (0.71–1.07%) and subsequent translocation of the absorbed Zn (23–66%). Foliar zinc treatment also improved growth attributes such as leaf area, height, spikelet per spike, number of grains per spike, grain yield, leaf and grain Zn content, and grain protein content. These findings suggest a need for cautious parent selection in devising the breeding strategies intended for biofortification.

“…Liu et al (2017) further revealed that adequate zinc supplied led to assimilation of the available supply nutrients. Yaser et al (2016) reported that zinc application at rates of 7 and 10.50 had minimum numbers of days (157 days) to physiological maturity. Guo et al (2016) reported that applying zinc sulphate between 5-10kg Zn/ha is suitable for correcting zinc in rice through a basal application.…”

INC is the most important micronutrient that limits crop production. Sorghum is highly susceptible to zinc deficiency. A green-house experiment was carried out at North-West University Research Farm to assess the effect of zinc fertilizer rates on the performance of different grain sorghum cultivars. The experiment was set as a 4 x 3 factorial fitted in a randomized complete block design. The treatment factors comprised three zinc rates (0, 5.6 and 10.6kg Zn/ha) and four grain sorghum cultivars (Avenger, Enforcer, NS5511 and PAN 8816). The measured parameters were plant height, number of leaves, chlorophyll content index, stem dry matter, leaf area, total dry matter, and panicle mass. The sorghum fertilized with 5.6kg Zn kg/ha had the highest chlorophyll content (69.90) at 77 days after planting. The highest chlorophyll content (70.90) was recorded with the Enforcer cultivar. The longest flowering days (83.93 days) was recorded with the application of 10.6 Zn kg/ha. The application of 10.6 Zn kg/ha produced the highest total dry weight of 370.20g and 93.00g, respectively. The PAN 8816 had the highest panicle mass (105.80g). The relationship between zinc rates, total dry matter, and panicle mass was positive and significant (R 2 = 1). Therefore, the application of 5.6 Zn kg/ha enhanced the growth of grain sorghum and 10.6 kg Zn/ha improved dry matter accumulation and panicle production. The Enforcer outperformed other cultivars for growth purposes, and PAN 8816 performed the best for panicle production.

Long-Term Zinc Fertilization in Calcareous Soils Improves Wheat (Triticum aestivum L.) Productivity and Soil Zinc Status in the Rice–Wheat Cropping System

Rice–wheat cropping system (RWCS) is considered as the furthermost vital system in the Indo-Gangetic Plains of South-Asia, including India, Pakistan, Bangladesh, and Nepal. Recently, the deficiency of micronutrients like zinc (Zn) has emerged as one of the prime limitations for the sustainability issues of this RWCS in Zn deficient calcareous soils, particularly in India, as a result of the calcareous typic ustifluvents taxonomic nature of the soils. Therefore, a new Zn fertilization approach for soils is very much needed in the intensive RWCS. Thus, a six-year-long investigation was designed with three different modes of Zn application, viz., the application of Zn only in the first year of study, application in alternative years, and application in every year. Four different rates of Zn applications in a hectare of area for a single year, viz., 2.5, 5.0, 7.5, and 10 kg ha−1 year−1, and times of Zn application, viz., only at first year, alternative years, and in each year. The major aims of the study were to determine Zn concentration in soil; yield; and Zn accumulation by wheat crop under different application methods of Zn. From this study, it was found that a large portion of the applied Zn was present in the residual fraction, and it was also revealed that increasing the frequency of Zn application resulted in the increment in the crystalline fraction. Significant correlation of water-soluble and exchangeable Zn (WS+EX-Zn), complexed Zn (COM-Zn), amorphous Zn (AMO-Zn), organic Zn (ORG-Zn), total Zn (TOT-Zn), grain yield, and grain Zn uptake by wheat indicated that these Zn fractions were dominant forms in the soil to be utilized by plants under rice–wheat rotation. Concerning yield and Zn uptake by wheat, it was noted that the Zn application at 10 kg ha−1 in alternate years was the best Zn application method, while application of Zn at 7.5 kg ha−1 in each year also resulted in comparable yield.
