“…However, previous study in the same location disseminated that Zinc application in maize measured up almost 3% in grain yield when applied at 20 kg ha −1 dose [22]. In addition, several studies reported, application of micronutrients in combination to macronutrients, increased yield and grain quality in maize [73][74][75]. Thus, studies on effect of Zinc and other micronutrients in maize, should be extensively done in Nepal to quantify the actual impact.…”

The optimum dose of fertilizers for crops varies with soil, agro-ecology, and crop management practices. Optimizing application dose is critical to reduce nutrient loss to the environment and increase nitrogen use efficiency (NUE), crop yields, and economic return to farmers. An experiment was conducted to determine the optimum N dose for increasing maize (Zea mays L. cv, Manakamana-3) yield, NUE, and farm profits under rainfed conditions. Five levels of N (0, 60, 120, 180, and 240 kg ha−1), and a non-fertilized treatment were tested in a randomized complete block design with three replications. Effects of each treatment on yield and yield attributing traits, plant lodging and Sterility (plants with no cob or grain formation), NUE, and stay green trait of maize were recorded. Application of N above 120 kg ha−1 (N120) did not have any significant effects on yield and yield components. Nitrogen, at N120 and above, produced highly fertile plants (though sterility slightly increased at N180 and N240), higher N uptake, and lower dead leaf area (18–27%). N120 produced the highest agronomic; yield increase per unit of N application (AEN—26.89 kg grain kg−1 N) and physiological efficiency of N (PEN—42.67 kg grain kg−1 N uptake), and net benefit (USD 500.43). Considering agronomic, economic, and NUE factors, an N dose of 120 kg ha−1 was found optimum for the cultivation of rainfed maize (Manakamana-3) under sandy loam soil.

“…Matusso and Materusse (2016), reported that the yield characters and grain yield increased significantly with increase in nitrogen level. Ruffo et al (2016) documented that application of zinc at higher level gave higher yield than control treatment in maize. Adhikari et al (2021) reported that the different levels of nitrogen had a significant effect on grain yield.…”

The experiment was laid out on the effect of nitrogen and zinc on growth and yield of maize (Zea mays L.) at Research Farm of the Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, India during kharif (July to October) season of 2017. The experiment was laid out in randomized block design three replication with eight treatments. The soil of the experimental field was Gangetic alluvial having clay loam texture with pH 7.5. It was moderately fertile, with available nitrogen (285.24 kg ha-1), available phosphorus (26.15 kg ha-1), available potassium (250.84 kg ha-1) and available zinc (1.42 mg kg-1). The maximum growth parameter viz. plant height (cm), LAI (%), dry matter accumulation (g) and the highest yield attributes and yield parameters viz., number of cob-1, length of cob (cm), test weight (g), number of grain cob-1, grain yield (q ha-1), stover yield (q ha-1), biological yield (q ha-1) and harvest index (%) was recorded at 30, 60, 90 DAS and at harvest stage with the application of nitrogen @150 kg ha-1++zinc @30 kg ha-1 which was at par with the treatments namely; nitrogen @150 kg ha-1++zinc @15 kg ha-1 and nitrogen @150 kg ha-1. All the treatments significantly influenced the growth and yield attributes as compared to control. The maximum net returns (` 89977 ha-1) and benefit:cost ratio (1.58) has been recorded with application of nitrogen @150 kg ha-1++zinc @30 kg ha-1.

“…For example, Ruffo et al. (2016) reported that corn fertilized with MESZ or granular ZnSO 4 blended with granular fertilizers at a rate of 2.24 and 11.2 kg Zn ha −1 , respectively, produced similar yields that were greater than the yield of corn receiving no Zn fertilizer. Slaton et al.…”

Low-use-rate Zn fertilization methods have been developed and marketed for rice (Oryza sativa L.) fertilization with limited research validating their efficacy. Our research objectives were to evaluate the effect of Zn-seed treatment rate combined with six Zn-fertilization methods on early season canopy coverage, tissue-Zn concentration at the mid-tillering stage, and rice grain yield. The field experiment was conducted on six silt loams and one clay. Rice seed was treated with 0 or 3.3 g Zn kg −1 as ZnO and combined with no Zn, granular ZnSO 4 applied at 11 kg Zn ha −1 (GRAN), 1.68 kg Zn ha −1 as MicroEssentials (MESZ), 1.1 kg Zn ha −1 as foliar-applied Zn-EDTA (EDTA), and 0.56 and 1.12 kg Zn ha −1 of WolfTrax Zn-DDP (DDP). Canopy coverage of seedling rice was measured at six sites and analyzed by site. Four sites were not affected by Zn-seed treatment rate or fertilization method. At two sites, canopy coverage was affected by Zn-fertilization method or the significant Zn-seed treatment rate and Zn-fertilization method interaction. Rice receiving MESZ had the greatest canopy coverage at these sites. When averaged across sites and Zn fertilization methods, seed treated with 3.3 g Zn kg −1 increased seedling tissue-Zn concentration and biomass by 1.6 mg Zn kg −1 and 48 kg ha −1 respectively. Rice receiving GRAN, increased tissue-Zn concentration by 7.6 mg Zn kg −1 above rice not receiving Zn (21.3 mg kg −1 ). Low-use-rate Zn fertilizers provide minimal Zn nutrition for rice seedlings and should be avoided on fields where Zn deficiencies are probable.
