Effects of foliar application of urea and potassium chloride on some physicochemical properties of “Damson ”plum fruits

Soil moisture stress in lentil (Lens culinaris L.) cultivated in rice (Oryza sativa L.) fallows of Tripura (50 m above msl), India, is one of the issues related to low productivity. Effects of foliar feeding of lentil with urea and potassium chloride KCI @ 2% each, singly or in combination either at 50% flowering, 50% podding or both at 50% flowering + 50% pod formation stages under moisture stress condition were investigated. The key physiological parameters viz. chlorophyll a, chlorophyll b, total chlorophyll content, leaf relative water content (LRWC), excised leaf water loss (ELWL) and yield attributes of lentil were measured. There were significant plessthan0.05) increases in chlorophyll a, chlorophyll b and total chlorophyll content at 50% flowering and 50% pod formation stage in plants treated either with 2% KCl alone or in combination with 2% urea as compared to those under control and 2% urea alone. Further, LRWC and ELWL were the highest (83%) and lowest (0.7%) under combined application of two agro chemicals, respectively. Significant (plessthan 0.05) increases in plant height, number of branches per plant, numbers of pods per plant and biomass as well as seed yield were also observed with combined foliar application of agrochemicals in comparison to those under control. The highest LRWC and lowest ELWL were recorded in case of foliar spray at 50% flowering + 50% pod formation as compared to either 50% flowering or 50% pod formation stage alone. Foliar application of both agro-chemicals mitigates the terminal moisture stresses especially in underutilized rice-fallow lands for successful cultivation of rabi crops like lentil.

Abstract The aim of this study was to explore the efficiency of foliar potassium fertiliser relative to morphological, physiological and biochemical properties of hybrid long pepper (Capsicum annuum). Pepper plants were grown in a greenhouse and supplied with three sources of foliar potassium fertilisers, i.e., potassium-humate (1 g/L = 1,250 g/ha), potassium sulfate (1 g/L = 1,250 g/ha), and potassium chloride (1 g/L = 1,250 g/ha). Water served as control. The impacts of these treatments on the phytosynthetic parameters (photosynthetic rate, stomatal conductance, intercellular CO2, leaf carotenoids) and chlorophyll a and b, metabolic compounds and nitrogen, phosphorus and potassium were measured. The phytosynthetic parameters significantly improved by different foliar potassium application and the highest level of photosynthetic activity was noted in plants supplied with potassium sulfate, followed by potassium-humate and potassium chloride. Plant biomass accumulation, cholorophyll (a and b), and total yield showed larger increases in plants fertilised with potassium sulfate than those fertilised with potassium-humate; smallest increases occurred with potassium chloride. Concentrations of total sugars, carotenoids, chlorophyll (a and b), and endogenous level of nitrogen, phosphorus, and potassium contents in plants and fruits were possitively influenced by varying sources of potassium. The fruit color parameters and total soluble solid were also significantly increased with all foliar potassium treatments compared with control. Foliar application of potassium sulfate recorded the highest values and significantly increase all anatomical characters for leaf, stem and fruit of pepper plant.

Reducible Oxides

The industrial importance of metal catalysts supported on reducible oxides has stimulated considerable interest during the last few years. This presentation reports on the study of the physicochemical properties of metallic rhodium supported on vanadium pentoxide (Rh/V2O5). Electron optical methods, in conjunction with other techniques, were used to characterise the catalyst before its use in the hydrogenolysis of butane; a reaction for which Rh metal is known to be among the most active catalysts.V2O5 powder was prepared by thermal decomposition of high purity ammonium metavanadate in air at 400 °C for 2 hours. Previous studies of the microstructure of this compound, by HREM, SEM and gas adsorption, showed it to be non— porous with a very low surface area of 6m2/g3. The metal loading of the catalyst used was lwt%Rh on V2Q5. It was prepared by wet impregnating the support with an aqueous solution of RhCI3.3H2O.

Rapid Appearance

SummaryThe effects of trypsin and plasmin on the functional and physicochemical properties of purified human fibrinogen were observed at various stages of proteolysis. Concentrations of plasmin and trypsin that produced fibrinogenolysis at comparable rates as measured in a pH stat produced, at similar rates, loss of precipitability of fibrinogen by heat and ammonium sulphate and alterations in electrophoretic mobility on starch gel. Trypsin produced a more rapid loss of clottability of fibrinogen and a more rapid appearance of inhibitors of the thrombin-fibrinogen clotting system than did plasmin. Consistent differences were noted between the effects of trypsin and plasmin on the immunoelectrophoretic properties of fibrinogen during the early stages of proteolysis.These results are consistent with the hypothesis that trypsin initially reacts with the same peptide bonds of fibrinogen that are split by thrombin, but these same bonds do not appear to be split initially by plasmin. Measurement of the various functional and physico-chemical changes produced by the action of trypsin and plasmin on fibrinogen can be used to recognize various stages of proteolysis.
