RÉSUMÉ

The present investigation entitled “Effect of Micronutrients Foliar Application on Growth and Flowering of Gerbera (Gerbera jamesonii) in Naturally Ventilated Polyhouse Under Prayagraj Agro Climatic Conditions” was carried out during November 2022 to March 2023 in, Naturally Ventilated Polyhouse, Department of Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj. The experiment was conducted in Randomized Block Design with thirteen treatment combinations, with the application of three micronutrients; FeSO4, MgSO4 and ZnSO4 at different levels, which was replicated thrice. It was concluded that the application of micronutrients treatments rendered their significant effect on almost all the growth, flowering and yield characters of gerbera. The treatment T11 i.e., application of ZnSO4 at 0.6% found superior in terms of plant height (28.17cm), number of leaves (13.5), length of the leaves (33.9cm), plant spread (47.68cm), days taken for first flower bud initiation (88.6days), minimum days taken to first harvest (119days), flower diameter (11.35cm), stalk length (43.16cm), stalk diameter (7.16mm), number of flowers per plant (9.17) and vase life (9.66days). Among the different treatments the highest gross return (142590 Rs/200m2), Net return (55938 Rs/200m2), benefit cost ratio (1.64) was obtained under the use of ZnSO4 at 0.6% (T11).

RÉSUMÉ

A field investigation was conducted in Kharif (2022), at a Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). To study the “ Influence of foliar application of zinc on growth and yield of pearl millet (Pennisetum glaucum L.) varieties.” An experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. The treatments consist of three different pearl millet varieties (Kaveri super boss, Nutra pearl, Nandi-75) and foliar application of Zinc on 25 DAS and 25 and 50 DAS respectively. The experimental results revealed that significantly higher values of growth parameters viz., plant height (191. 87 cm), dry weight accumulation (58.75 g/plant), CGR (10.55 g/m2/day) and yield attributes viz., ear head length (19.50 cm), grains/ear head (1203.60), test weight (10.02 g), grain yield (1.37 t/ha), straw yield (1.70 t/ha) were recorded maximum in treatment (Kaveri Super Boss + ZnSO4 0.5% (at 25 and 50 DAS) T3. These parameters were significantly influenced by increasing the foliar spray of ZnSO4.

RÉSUMÉ

Background: Suboptimal dietary zinc intake is widespread in India due to low levels of plant-available zinc in soils and limited food choices. The aim of this study was to enhance the zinc concentration in soil and plant by using farmyard manure (FYM) enriched with zinc fertilizers and zinc solubilizers respectively. Additionally, the response of maize to three forms of zinc fertilizer was determined. Maize crop grown under zinc-deficient soils contain lower zinc concentration, which can cause human illness and a drastic effect on yield can be noticed. Therefore, enhancing zinc content in plants by using FYM enriched with zinc solubilizers and inorganic zinc fertilizers is the best approach to increase zinc content in soil and plants. Methods: A field experiment was conducted to study the physico chemical properties of soil under maize (Zea mays L.) in response to the application of FYM enriched with ZnSB and ZnSO4 on sandy loam soils at College Farm, Agricultural College, Mahanandi campus of Acharya N. G. Ranga Agricultural University during rabi, 2021-2022. The experiment was laid out in randomized block design with eleven treatments and replicated thrice. Results: The results revealed that significantly higher and comparable values of available nitrogen (302, 299 and 281 kg ha-1 respectively), phosphorous (73.40, 66.53 and 58.40 kg ha-1 respectively) and zinc (1.76, 1.54 and 1.15 mg kg-1 respectively) at different growth stages of maize were registered with application of FYM @ 10 t ha-1 enriched with ZnSO4 @ 50 kg ha-1. Whereas available potassium, Iron, manganese, copper, soil pH, EC (dS m-1) and OC (%) were not significantly affected by the application of FYM enriched with ZnSB and ZnSO4.

RÉSUMÉ

Salt stress as a major adverse factor can lower leaf water potential, leading to reduced torgor and some other responses, and ultimately lower crop productivity in arid and semi arid zone. Plant responses to salt stress have much in common. Salt stress reduces the ability of plants to take up water and this quickly causes reductions in growth rate. The initial reduction in shoot growth is probably due to salt effects. If excessive amounts of salt enter into the plant, salt will eventually rise to toxic levels and reduce the photosynthetic leaf area of the plant that cannot sustain growth. In order to understand the processes that give rise to tolerance of salt and to identify the salt stress proteins in the salt stress effect of on plant growth was studied using different salt solutions like Copper sulphate, Cadmium chloride and zinc sulphate with different concentrations like 200μM, 150μM, 100μM.

RÉSUMÉ

BACKGROUND AND OBJECTIVES: The purpose of this study was to evaluate the time course of functional and anatomical recovery of the olfactory epithelium (OE) and olfactory bulb (OB) following intranasal instillation of 1% ZnSO4 in mice. MATERIALS AND METHOD: Two groups of mice, normal control group (intranasal instillation of normal saline, n=6) and experimental group (intranasal instillation of ZnSO4, n=18), were studied. Tissues of olfactory pathways were obtained at 1, 3 and 5 weeks after bilateral intranasal instillation of 1%, 100 microliter ZnSO4 solution, and processed for immunohistochemistry using antisera, olfactory marker protein (OMP), proliferating cell nuclear antigen (PCNA) and tyrosine hydroxylase (TH) to evaluate the olfactory regeneration. For histological study, OE thickness stained with hematoxylin-eosin was analyzed. RESULTS: At 1 week after ZnSO4 intranasal instillation, the lowest peak of OMP expression in OE appeared. Then the number of OMP-positive cells increased progressively at weeks. However, PCNA expression in OE showed quite the opposite. In the corresponding OB at 1 week, there was decrease of TH-positive cells and at 3 weeks, there was few TH-positive cells. At 5 weeks, there was increase in the number of TH-positive cells again. OE thickness was reduced to 20% of control OE at 1 week, and was significantly recovered to 80% of control OE at 5 weeks. CONCLUSION: Our results demonstrated that intranasal instillation of 1% ZnSO4 to mice produces a brief, reversible but essentially complete destruction of functional connection from the olfactory epithelium to the main olfactory bulb.

RÉSUMÉ

The antiarrhythmic actions of ZnSO4 (Zinc) were studied in ex-perimental arrhythmias models. ZnSO4 10mg/kg(iv) significantly coun-teracted the arrhythmias, induced by aconitine or BaCl2 rats.It was shown to shorten the duration of arrhythmias induced by chloroform-epinephrine in rabbits. In mice, ZnSO4 20 ?g/10g(ip) decreased the incidence of ventricular fibrillationbychloroform. However, ZnSO4 did not decrease the incidence of CaCl2-induced , venticular fibrillation, the threshold and lethal doseofouabain in producing ventricular permature beats, ventricular fibrillation in guinea pigs.
