“…These two factors (cell division and cell elongation) led to the increase of the stem height. These results were in agreement with the reports of Malik et al [27], Nadergoli et al [28] and Manasa and Devaranavadagi [29]. Increase of crop height with B application might be due to the effect of B for proper development and differentiation of tissues, particularly growing tips, phloem and xylem [30].…”

A field experiment had been conducted during spring season of 2016-2017 and 2017-2018 at Regional Research Sub-station of Bidhan Chandra Krishi Viswavidyalaya, Raghunathpur, Purulia, West Bengal with the objective to study the effect of micronutrient application with different sources of NPK on growth and productivity of finger millet. The experiment was laid out in split plot design with two main plot treatments (sources of NPK, F 1 : 100% recommended dose of NPK (RDF) i.e., N:P 2 O 5 :K 2 O, 40:20:20 kg/ha, F 2 : 75% RDF + 2.5 t/ha farmyard manure (FYM)) and six subplot treatments (method and dose of micronutrient application, M 1 : ZnSO 4 at a rate 12.5 kg/ha as soil application, M 2 : ZnSO 4 at a rate 0.5% as foliar spray, M 3 : borax at a rate 10 kg/ha as soil application, M 4 : borax at a rate 0.5% as foliar spray, M 5 : ZnSO 4 at a rate 12.5 kg/ha + borax at a rate 10 kg/ha as soil application and M 6 : ZnSO 4 at a rate 0.5% + borax at a rate 0.5% as foliar spray) with three replications. The results of the experiment indicated (from pooled data) that there was a significant influence of sources of NPK and application of micronutrients on growth and performance of finger millet. The highest grain yield (2.24 and 2.30 t/ha) was recorded by 2.5 t/ha FYM + 75% RDF in combination with ZnSO 4 at a rate 0.5% + borax at a rate 0.5% foliar spray. So, organic and inorganic combination of NPK (75% RDF + 2.5 t/ha FYM) along with foliar application of both the micronutrients (Zn and B) together can boost up the yield and could be recommended for the cultivation of finger millet crop in red and laterite zone of West Bengal.

“…Plant physiological and biochemical features are normally altered in response to metal stress. Previous studies reported that plants suffering from Zn toxicity experienced limits in root and shoot growth (Malik et al 2011) similar to plants exposed to Pb (Sharma & Dubey 2005) and Cu (Fernandes & Henriques 1991). Biochemical processes such as respiration and photosynthesis are also compromised due to interference from these metal elements (Keunen et al 2011).…”

Heavy metal pollution leads to human health problems and represents a constant threat to the environment. Pollutant clean-up using conventional methods are often hampered by high cost and ineffective pollutant removal. Phytoremediation technique is a preferable alternative due to its minimal side effects to the environment in addition to reasonable treatment cost. In this study, we investigated the potential of Centella asiatica and Orthosiphon stamineus as phytoremediation agents. Both species were grown in contaminated soil obtained from industrial land. Plant growth response and their ability to accumulate and translocate zinc, copper and lead were assessed. From this study, root growth of C. asiatica was compromised when grown in contaminated soil. Copper was highly accumulated in C. asiatica roots while the leaves were more concentrated with zinc and lead. Conversely, all three tested metals were highly detected in the roots of O. stamineus, although the root elongation was not adversely affected. Low amount of metals in the stems of both species permits longer stem length. Correlation study showed that the accumulation of zinc, copper and lead in plant tissues varies depending on plant species and the type of metals. Based on the bioaccumulation, translocation and enrichment factor, our study showed that C. asiatica was tolerant towards zinc, copper and lead; hence suitable for phytoextraction. By contrast, O. stamineus acted as a moderate accumulator of the tested metal elements.

“…The normal content of zinc in plants varies between 10 -150 ppm (Mulligan et al, 2001) or between 25ppm -150ppm (Malik et al, 2011); in concentrations of 400 ppm it becomes toxic (Mulligan et al, 2001). Depending on the tolerance of plant to zinc excess, the toxic level can be lower (Băjescu and Chiriac, 1984).…”

Abstract. The paper presents the results of a study regarding the influence of treatment with zinc in different concentrations (50 mg∕l, 100 mg∕l, 200 mg ∕l, 300mg/l, 400 mg ∕l, 500 mg/l, 600 mg ∕l) on seed germination and growth in early ontogenetic stages of Cucumis melo L. We analyzed the following indicators: the percentage of germinated seeds; the length of root, the length of the hypocotyl and the length of the seedling; the number of the laterale roots; the tolerance index and the seedling vigor index. The results underline the specific variations of analysed indicators, depending on the concentrations used for the treatments of seeds. The concentrations used for treatment do not influence negatively the seed germination, but affected the seedling growth (especially the root elongation), the formation and growth process of lateral roots and the seedling vigour index. The delay effect of growth process is very pronounced in the case of high concentration. IntroductionThe heavy metals come from natural sources and from anthropogenic sources. In certain concentration, the heavy metals become pollutants with toxic potentially; they persist a long time in the environment because of their reduced mobility and can transferred along food chains. Environmental pollution with heavy metals presents a risk for plants, animals and for man. Some heavy metals (zinc, copper, etc) are important for the life of plants; other heavy metals (lead, cadmium, etc) do not have a biological role.
