Molybdenum deficiency occurs when plant growth is limited because the plant cannot take up sufficient quantities of this essential micronutrient from its growing medium. Meagher et al. � ��ʜk�^ 0000046037 00000 n Modern intensive agriculture gradually gains higher interest and importance of micronutrients to the researchers due to the diverse functional activities on plants. Molybdenum is essential for nitrogen metabolism, where it is a key component of the enzyme nitrate reductase, which catalyzes the first step of the conversion of nitrate-N into plant N compounds. For instance, the lack of one small ounce of molybdenum (Mo) per acre can lower disease resistance by impeding the production of nitrate reductase. This publication provides information on plant nutrition and soil fertility for agricultural and urban plant production and management practitioners. Role of Molybdenum in Horticultural crops Molybdenum is a trace element found in the soil and is required for growth of most biological organism including plants (0.1-2.0 mg kg-1 plant dry matter) and animals. activities on plants.

Its deficiency can significantly reduce N metabolism and tree … We propose that effects of boron deprivation on DNA synthesis and mitosis in sunflower are secondary and that primary events involve alterations in cellular membranes. However, [3]. Documentation on the function of Molybdenum (Mo) and Boron (B) on the growth and production of the crops were not accounted considerably. Legumes need more molybdenum than other crops, such as grass or corn, because the symbiotic bacteria living in the root nodules of legumes require molybdenum for the fixation of atmospheric nitrogen. Molybdenum (Mo) is present as a pterin-cofactor in the active center of plant enzymes catalyzing key steps of nitrogen, carbon, and sulfur metabolisms, making them essential for efficient growth under the diverse environmental conditions. and in the soil that supports plants, in that these elements are essen­ tial for the life or optimum health of the organisms. Node growth is retarded in soils with low molybdenum. Dry your plants out first. Scintillation counting of whole root tips shows that boron-deficient roots up to 72 hr of treatment incorporate radioactive label at a level comparable to that of the controls. IOSR Journal of Agriculture and Veterinary Science, Australian Journal of Basic and Applied Sciences. However, to what extent can nano hydroxyapatite (NHA) and nano-boron oxide (NBO) be suitable substitutes for calcium superphosphate(CSP) and boric acid (BA)?

Yellowish-re colored yound g leave Figurs 2. Molybdenum is an essential component in two enzymes that convert nitrate into nitrite (a toxic form of nitrogen) and then into ammonia before it is used to synthesize amino acids within the plant. It’s very rare to have a molybdenum deficiency, but it does happen from time to time. italica) Grown on A Heavy Clay Soil? 0000002871 00000 n It is involved in several different processes, including photosynthesis, which nearly all living organisms are dependent on. We found that mitosis in inhibited in -B roots but does not completely cease. Molybdenum is a chemical element with the symbol Mo and atomic number 42. In the majority of agricultural soils, the content of molybdenum is somewhere in the range of 0.6 ppm – 3.5 ppm […] In the form of molybdate the transition metal molybdenum is essential for plants as it is required by a number of enzymes that catalyze key reactions in nitrogen assimilation, purine degradation, phytohormone synthesis, and sulfite detoxification. ... role in plants, in the absence of any particular element, plants show certain 0000002147 00000 n Our preliminary results using an autoradiographic analysis of sunflower roots labeled with [³H]-thymidine demonstrated no difference in label distribution between +/-B root tips. Nano-fertilizers are effective substitutes for the traditional ones. Plants require trace amounts of molybdenum (Mo) for normal growth. Although, production is not enough to meet the requireme.

Molybdenum(VI) can be reduced to the +5 and +4 oxidation states quite readily, and so its biological role seems to be that of an electron 'sink' in redox processes. In this review, the role of molybdenum in plants is discussed, focusing on its current constraints in some agricultural situations and where increased molybdenum nutrition may aid in agricultural plant development and yields.
