“…A recent study (Diatta, unpublished data, 2019) documenting adaptation and performance of mungbean genotypes also reported that 8735 (1284 kg ha −1 ) and IC 8972-1 (739 kg ha −1 ) genotypes had higher dry matter yields than STB #122 (635 kg ha −1 ), 223 (156 kg ha −1 ), and Berken (441 kg ha −1 ) genotypes. Differences among mungbean genotypes were also observed by Mondal et al (2012) and Haider et al (2020) due to greater leaf area, branches per plant, and increased crop growth. Chauhan and Williams (2018) attributed variations in biomass accumulation in mungbean to leaf area index, light extinction coefficient, duration of light interception, and radiation use efficiency.…”

Ensuring food and nutritional security in light of high climate variability and a rapidly growing population remains a challenge. Mungbean (Vigna radiata (L.) Wilczek) is a short duration, drought-tolerant, and ureide-exporting legume crop capable of symbiotic atmospheric nitrogen fixation. Estimates of biological N 2 fixation by mungbean in different soil textures have not been extensively studied. We conducted this study to evaluate plant growth and N 2 fixation of five mungbean genotypes (Berken, 8735, IC 8972-1, STB#122, 223) inoculated with Bradyrhizobium spp. and grown on loamy sand and silt loam soils under glasshouse conditions. Mungbean dry matter yield, δ 15 N values, shoot content, amounts of N-fixed, and soil N uptake were all higher on the silt loam soil compared to the loamy sand soil, demonstrating the effects of soil properties on plant growth and N 2 fixation potential. Among genotypes, IC 8972-1 produced the highest biomass (7.85 g plant −1), shoot N content (200 mg plant −1), and soil N uptake (155 mg plant −1) than other genotypes. The significant interaction between soil texture and genotypes for root dry matter and %Ndfa indicates the major role of legume root-nodule bacteria in symbiotic N 2 fixation. This study demonstrated that N 2 fixation in mungbean is affected by both genotypes and soil properties, illustrating the need to consider soil properties in order to maximize N contribution from mungbean to agricultural production systems.

“…Better allometric traits with Zn-fertilization might be attributed to the association of Zn with the synthesis of nucleic acid, protein, lipids, carbohydrates, nitrogen metabolism, photosynthesis, cell division and other related cell processes [36][37][38]. Better root growth and improved number of lateral roots might be attributed to involvement of Zn in the stimulation of several metabolic enzymes in the root cells [39], which promote cell division and elongation [11,12,[27][28][29]. Zinc fertilization improves the resistance against abiotic stresses by improving the root morphology and physiology [40], which ultimately enhances root growth.…”

Zinc (Zn) is an important micronutrient for crop plants and essential for human health. The Zn-deficiency is an important malnutrition problem known globally. Biofortified foods could overcome Zn deficiency in humans. Mungbean [Vigna radiata (L.) Wilczek] is an important, pulse crop frequently grown in arid and semi-arid regions of the world. Mungbean could provide essential micronutrients, including Zn to humans. Therefore, it is very important to investigate the impact of Zn fertilization on the yield and grain biofortification of mungbean. Twelve mungbean genotypes (i.e., NM-28, NM-2011, NM-13-1, NM-2006, NM-51, NM-54, NM-19-19, NM-92, NM-121-25, NM-20-21, 7006, 7008) were assessed for their genetic diversity followed by Zn-biofortification, growth and yield under control (0 kg ha-1) and Zn-fertilized (10 kg ha-1) conditions. Data relating to allometric traits, yield components, grain yield and grain Zn contents were recorded. Zinc fertilization improved entire allometric and yield-related traits. Grain yield of different genotypes ranged from 439 to 904 kg ha-1 under control and 536 to 1462 kg ha-1 under Zn-fertilization. Zinc concentration in the grains varied from 15.50 to 45.60 mg kg-1 under control and 18.53 to 64.23 mg kg-1 under Zn-fertilized conditions. The tested genotypes differed in their Zn-biofortification potential. The highest and the lowest grain Zn contents were noted for genotypes NM-28 and NM-121-25, respectively. Significant variation in yield and Zn-biofortification indicated the potential for improvement in mungbean yield and grain Zn-biofortification. The genotypes NM-28 and NM-2006 could be used in breeding programs for improvement in grain Zn concentration due to their high Zn uptake potential. Nonetheless, all available genotypes in the country should be screened for their Zn-biofortification potential.

“…Agronomic biofortification practices, such as addition of Zn fertilizers, either to soil and/or foliar, are generally followed to mitigate soil Zn deficiency and enhance plant growth and yield, and grain Zn concentration and uptake [ 8 ]. Compared to Zn application to soil, application of Zn to foliar or both soil and foliar were found to be more effective for augmenting Zn uptake by crop seed and/or grain [ 9 , 10 , 11 ].…”

Pigeonpea (Cajanus cajan (L.) Millsp.) is grown globally for its protein-rich seed. However, low availability of soil zinc (Zn) adversely affects the seed yield of pigeonpea. The present study was therefore conducted to assess the Zn efficiency of pigeonpea genotypes based on seed yield and seed Zn uptake efficiency. Field experiments were conducted at the Indian Council of Agricultural Research–Indian Institute of Soil Science, Bhopal, India with twenty different pigeonpea genotypes and two levels of Zn application under a split-plot design. The two levels of Zn were low (without application of Zn fertilizer) and high (with application of 20 kg Zn ha−1 (as ZnSO4∙7H2O) as basal soil application, in conjunction with three foliar sprays of 0.50% (w/v) ZnSO4∙7H2O aqueous solution) (with 0.25% lime as neutralizing agent) at flowering, pod formation, and pod filling stages). Application of Zn improved plant height, branches plant−1, pods plant−1, seeds pod−1, and 100 seed weight of pigeonpea genotypes differently. The mean seed yield, seed Zn concentration, and seed Zn uptake of the genotypes increased from 1.71 to 2.12 t ha−1, 32.4 to 43.0 mg kg−1, and 54.9 to 90.6 g ha−1, respectively, with application of Zn. The seed yield efficiency index (SYEI) and Zn uptake efficiency index (ZUEI) of pigeonpea genotypes varied from 67.0 to 92.5 and from 47.0 to 69.9, respectively. Based on SYEI and ZUEI, the genotypes were classified as efficient and responsive (Virsa Arhar-1, GT-1, GT-101, SKNP 05-05, BDN-2, AAUT 2007-04, BSMR 853, T 15-15, DT 23, Pusa 9), efficient and non-responsive (ICPL 87119, PKV Trombay), inefficient and responsive (AKT 8811, Hisar Paras), and inefficient and non-responsive (AAUT 2007-10, JKM 7, Hisar Manak, C 11, Hisar HO2-60, GAUT 93-17). The efficient and responsive genotypes are the most useful as they yield well under low soil Zn conditions and also respond to Zn fertilizer application. The inefficient and responsive genotypes could be utilized for plant breeding programs by plant breeders for identification and utilization of responsive traits.
