“…The foliar spray of Mo at the rate of 0.025 per cent or 0.050 per cent had increased all the 3 root parameters followed by soil application of Mo and seed treatment. Foliar spray of Mo had increased the dry matter by 3 to 4 times, root length by 2.5 times and volume by 2 times indicating the importance of foliar spray of Mo in root proliferation and dry product.This data is in accordan findings of [13].…”

The role of molybdenum (Mo) in greengram in regulating the activities of enzymes such as nitrate reductase (NR) and glutamine synthetase (GS) in particular to nitrogen assimilation was investigated in acid soils of Semi-arid Tropics (SAT) of Tamil Nadu. Incubation studies were taken up with two sources of molybdenum namely sodium molybdate (Na 2 MoO 4 ) and ammonium molybdate ((NH 4 ) 6 Mo 7 O 24 ) in which sodium molybdate proved to be a better performer and recommended as Mo fertiliser in SAT acid soils. Application of Mo increases root, shoot length and biomass. It also increases the number of nodules and rhizobium population in green gram. In particular to microbial aspect the rhizobium population count serial dilution technique was followed. The anatomy of the nodule was imaged using high-resolution imaging Scanning Electron Microscope (FEI SEM Quanta 250, Netherlands).

“…The present findings are concordant with previous studies, where Mo supplementation increased the Mo concentration in ‘ Le-Conte ’ pear [ 37 ], grapes (cv. Merlot) [ 38 ], peanut [ 39 ] and lettuce [ 40 ]. Togay et al [ 41 ] also reported the enhanced concentration of Fe, P, Mn, Cu and Mo in lentil ( Lens culinaris Medic.)…”

Interactive Effects of Molybdenum, Zinc and Iron on the Grain Yield, Quality, and Nodulation of Cowpea (Vignaunguiculata (L.) Walp.) in North-Western India

et al. 2022

Micronutrient deficiency is a major constraint for the growth, yield and nutritional quality of cowpea which results in nutritional disorders in humans. Micronutrients including molybdenum (Mo), iron (Fe) and zinc (Zn) play a pivotal role in crop nutrition, and their role in different metabolic processes in crops has been highlighted. In order to increase the nutritional quality of cowpea, a field experiment was conducted for two years in which the effect of Mo along with iron (Fe) and zinc (Zn) on productivity, nitrogen and micronutrient uptake, root length and the number of nodules in cowpea cultivation was investigated. It was found that the foliar application of Fe and Zn and their interaction with Mo application through seed priming as well as soil application displayed increased yield, nutrient concentration, uptake and growth parameters which helped to enhance the nutritional quality of cowpea for consumption by the human population. The results of the above experiments revealed that among all the treatments, the soil application of Mo combined with the foliar application of 0.5% each of FeSO4.7H2O and ZnSO4.7H2O (M2F3 treatment) enhanced the grain and stover yield of cowpea, exhibiting maximum values of 1402 and 6104.7 kg ha−1, respectively. Again, the M2F3 treatment resulted in higher Zn, Fe and Mo concentrations in the grain (17.07, 109.3 and 30.26 mg kg−1, respectively) and stover (17.99, 132.7 and 31.22 mg kg−1, respectively) of cowpea. Uptake of Zn, Fe and Mo by the grain (25.23, 153.3 and 42.46 g ha-1, respectively) as well as the stover (104.2, 809.9 and 190.6 g ha−1, respectively) was found to be maximum for the M2F3 treatment. The root length (30.5 cm), number of nodules per plant (73.0) and N uptake in grain and stover (55.39 and 46.15 kg ha−1) were also higher for this treatment. Overall, soil application of Mo along with the foliar application of FeSO4.7H2O (0.5%) and ZnSO4.7H2O (0.5%) significantly improved yield outcomes, concentration, uptake, root length, nodules plant−1 and N uptake of cowpea to alleviate the micronutrient deficiency.

“…Resultados similares foram obtidos por Steiner et al (2018), observando aumento de 33% do peso de folhas frescas quando aplicado Mo via fertilizante foliar. Neste trabalho, constatou-se como melhores resultados para MSF o valor de 33,96 g planta -1 para dose de 1,67 L ha -1 da combinação Spin ® + Fence ® , 20,09 g planta -1 para dose de 1,35 L ha -1 de Fence ® e 24,15 g planta -1 para dose 2,22 L ha -1 de Spin ® (Figura 1).…”

“…O fertilizante Spin, mesmo com menor concentração de elementos quando comparado ao Fence, demonstrou maior valor de MSF, isso provavelmente ocorreu devido ao elemento Mo participar de sua formulação. Steiner et al (2018) observou aumento de 28% de peso seco de folhas em tratamentos com Mo quando comparados a testemunha sem Mo.…”

“…Por apresentar ciclo rápido, esta cultura torna-se mais exigente em nutrientes, sendo observados pela deficiência destes, crescimento e coloração anormais, queima e má formação da planta (ALMEIDA et al, 2011), o que compromete a qualidade e, portanto, a comercialização do produto. Steiner et al (2018) realizaram aplicação de molibdênio via foliar em cultura de alface (Lactuca sativa L.), cultivar Grand Rapids, e obtiveram incremento de massa significativo no peso de folhas frescas e secas, com aumento de 33% e 28%, respectivamente. Costa et al (2018) trabalharam com pulverização de biofertilizante, e concluíram que houve incremento de massa fresca e na circunferência de plantas de alface crespa, variedade Verona.…”

A adubação foliar tem sido muito utilizada na agricultura como complemento à adubação de base do solo. Esta oferece uma vantagem específica em determinados estádios fenológico das culturas, quando uma alta demanda de nutrientes coincide com a oferta inadequada destes pelo solo. No presente trabalho avaliou-se a produção de alface cultivar Isabela®, em função da aplicação de fontes e doses de fertilizantes líquidos comerciais. A fase experimental foi realizada na área experimental do curso de Engenharia Agronômica da Universidade Paranaense, localizada no município de Umuarama-PR. Os tratamentos foram dispostos no delineamento de blocos ao acaso em esquema fatorial 3 x 4, constituído por três fertilizantes líquidos (Spin®, Fence®, e associação entre Spin® + Fence®) cuja composição consta N, P, K e Mo, e quatro doses (0; 1; 2 e 3 L ha-1), com quatro repetições. A colheita foi realizada 47 dias após o transplantio das mudas de alface. Analisou-se a massa fresca de folhas (MFF), massa seca de folhas (MSF), massa fresca de raízes (MFR) e o comprimento das raízes (CR) por planta. Os resultados indicaram que a aplicação das fontes Spin®, Fence® e associação entre Spin® + Fence®, proporcionaram influência positiva na produtividade da alface, beneficiando o incremento da MFF, MSF, MFR e CR. Os melhores resultados foram expressos pela associação entre Spin® + Fence®, na dose 1,67 L ha -1 , em todas as variáveis estudadas. Palavras-chave: adubação foliar; Lactuca sativa; produção. Productivity of lettuce cv. Isabela® under application of sources and doses of liquid fertilizers AbstractFoliar fertilization has been widely used in agriculture as a complement to soil base fertilization. This offers a specific advantage in certain phenological stages of crops, when a high nutrient demand coincides with the inadequate supply of these nutrients by the soil. In the present work the production of lettuce cultivar Isabela® was evaluated, due to the application of different sources and doses of commercial liquid fertilizers. The experimental phase was carried out in the experimental area of the Agronomic Engineering course of Universidade Paranaense, located in the city of Umuarama-PR. The treatments were arranged in a randomized complete block design in a 3 x 4 factorial scheme, consisting of three liquid fertilizers (Spin®, Fence®, and an association between Spin® + Fence®) whose composition is N, P, K and Mo, and four doses (0, 1, 2 and 3 L ha-1), with four replicates. Harvesting was performed 47 days after transplanting the lettuce seedlings. Fresh leaf mass (FLM), dry leaf mass (DLM), fresh root mass (FRM) and root length (RL) per plant were analyzed. The results indicated that the application of the Spin®, Fence® and Spin® + Fence® sources provided a positive influence on lettuce productivity, benefiting the increase of
