    A sensitive colorimetric method for the microdetermination of flavonols (1974)
    Springer
    Microchimica acta 62 (1974), S. 909-913

    Description / Table of Contents: Zusammenfassung Eine kolorimetrische Methode zur Bestimmung von Flavonolen wurde ausgearbeitet. Sie beruht auf der Bildung des intensiv gelb gefärbten Komplexes von Sb(III) mit Flavonolen, dessen Absorptionsmaximum bei 410 nm liegt. Die Farbe entspricht zwischen 0,4 und 6μg Quercetin/ml dem Lambert-Beer'schen Gesetz. Die Ergebnisse sind gut reproduzierbar. Catechine, Flavone, Flavonolglucoside sowie einige aromatische Hydroxysäuren stören nicht. Die einzelnen Flavonole lassen sich papierchromatographisch gut trennen und nach Elution bestimmen. Nach den Ergebnissen dieser Arbeit sind die 4-Carbonyl- und die 3-Hydroxygruppe an der komplexen Bindung des Metalls beteiligt. Das Verfahren erfordert keine Einstellung des pH, die im Fall der Flavonole auch nicht wünschenswert ist.
    Notes: Summary A colorimetric method for the quantitative determination of flavonols has been developed. The method is based on the reaction of the antimony(III) complex with flavonols to form an intensely yellow colour. The metal-flavonol complex has an absorption maximum at 410 nm. The Lambert-Beer law is obeyed in the concentration range of 0.4–6μg/ml for quercetin and the method is quite reproducible. Catechins, flavones and flavonol glycosides and some of the phenolic acids do not interfere. Individual flavonols can be efficiently separated by paper chromatography and estimated after elution from the chromatographic paper. Our results show that in the metal-complex formation, the 4-carbonyl and 3-hydroxy groups of the flavonols are involved. This method does not involve pH adjustment (which is not considered desirable in case of flavonols).

    Irrigation planning in cotton through simulation modeling (1996)
    Springer
    Irrigation science 17 (1996), S. 31-36 
    Details
    ISSN: 1432-1319

    Notes: Abstract Experiments were undertaken at CCS Haryana Agricultural University Farm, Sirsa (India) to estimate the optimum irrigation schedule for cotton resulting in minimum percolation losses. The sprinkler line source technique was adopted for creating various irrigation regimes at different crop growth stages. The SWASALT (Simulation of Water And SALT) model after calibration and validation provided water balance components. The wa-ter management response indicators (WMRI's) such as transpiration efficiency Et/(Irr + P), relative transpiration Et/Etp, evapotranspiration efficiency ET/(Irr + P), soil moisture storage change ΔW/Wint (deficit/excess) and percolation loss Perc/(Irr. + P) were evaluated using water balance components as estimated by the simulation study. Under limited water supply conditions, the optimum irrigation depth was found to be 57 mm at crop growth stages with pre-sowing and 1st irrigation of 120 mm and 80 mm respectively for sandy clay loam underlain by sandy loam soil (Type I). The corresponding values of relative transpiration, transpiration efficiency and evapotranspiration efficiency were 0.65, 0.65 and 0.89 respectively. The crop yield varied linearly with increasing irrigation depth which was evident from increase in relative transpiration with increasing depth of water application. However, increased depth of irrigation resulted in less moisture utilisation from soil storage (20% depletion at 40 mm depth and 4.4% moisture built up at 100 mm depth). The extended simulation study for sandy soil underlain by loamy sand (Type II) indicated that two pre-sowing irrigations each 40 mm and subsequent irrigations of 40 mm at an interval of 20 days depending upon rainfall were optimum. This irrigation scenario resulted in zero percolation loss accompanied by 74% relative transpiration and 14 per cent soil moisture depletion.

    Drainage disposal and reuse simulation in canal irrigated areas in Haryana (1997)
    Springer
    Irrigation and drainage systems 12 (1997), S. 1-22

    ISSN: 1573-0654
    Keywords: Intra-basin transfers ; water resources ; drainage effluent disposal ; reuse ; salinity modelling

    Notes: Abstract Nearly 60 per cent of the geographical area of Haryana state in Indian Union is underlain by saline ground water. The intra-basin transfer of surface water in the early sixties for irrigation has disturbed the hydrodynamic equilibrium resulting in waterlogging and salinization in large parts of the state. The existing inland drainage basin conditions did not permit the disposal of drainage effluent. The reuse system was therefore, integrated with the drainage system. A model RESBAL was coupled with the calibrated and validated on-farm water management model FAIDS and run for eight years to optimally design a series of connected reservoirs for the disposal of drainage effluent from an area provided with a subsurface drainage system. The possibility of the reuse of the disposed water for irrigation, aqua culture and salt harvesting was also studied comprehensively in order to maintain proper salt balance in the root zone.

    Influence of endosperm texture on milling, chemical composition and nutritive quality in maize (1989)

    Plant foods for human nutrition 39 (1989), S. 235-243

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Three maize varieties namely Vijay, SO/SN composite and Shakti, which differ in their nutritional quality and endosperm texture were processed to prepare semolina (sooji) and process-flour. The nutritional quality of these products was determined and compared with whole kernel flour of the respective variety. Distinct differences in milling and chemical composition of three varieties were recorded. In quality evaluation tests lysine and tryptophan content, biological value and true digestibility were better in semolina and process-flour. Moreover, decrease in acid value in semolina and process-flour compared with whole maize flour recorded in all the varieties suggested improvement in shelf-life.

    Description / Table of Contents: Résumé Des observations sur l'apparition du parasitoïdeApanteles angaleti Muesebeck et de ses 2 hôtes, le ver rose de la capsule du coton,Pectinophora gossypiella (Saunders) et la saprophyteSathrobrota simplex Wlsm, ont été réalisées de 1980–81 à 1983–84. La période d'apparition de l'adulte du parasitoïdeA. angaleti et deS. simplex était identique et s'achevait à la fin avril. Le parasitoïdeA. angaleti hivernait principalement dans les larves du saprophageS. simplex et non dans les larves du ver roseP. gossypiella. La multiplication précoce deS. simplex dans les capsules pourries des tas de coton aidait au transport et au développement initial d'A. angaleti lors de la principale saison de culture. Le début et l'apparition maximale de papillons chez le ver rose de la capsule variait en fonction des différentes sources de transport, mais tous les adultes se manifestaient jusqu'à la fin août.
    Notes: Abstract Observations on emergence pattern of parasitoidApanteles angaleti Muesebeck and its 2 hosts, cotton pink bollwormPectinophora gossypiella (Saunders) and saprophyteSathrobrota simplex Wlsm. were made during 1980–81 to 1983–84. The adult emergence of parasitoidA. angaleti and non-pestS. simplex was similar and completed by end April. ParasitoidA. angaleti overwintered mostly in the larvae of non-pestS. simplex and not in pink bollworm larvaeP. gossypiella. The early breeding activity ofS. simplex in the rotten bolls in the cotton stacks helped in the carryover and initial build-up ofA. angaleti to the main crop season. The initiation and peak moth emergence in pink bollworm varied with different sources of its carryover but all adults emerged until end August.
