    STABILITY ANALYSIS AND STANDARDIZATION OF PRODUCTION TECHNOLOGY FOR FLOWER AND XANTHOPHYLL YIELD IN MARIGOLD (Tagetes spp.)
    (University of Agricultural Sciences, Dharwad, 2003) HEMLA NAIK, B; PATIL, A A
    "Marigold is one of the important commercialflower crops of India, which ranks first among the loose flowers. It is not only grown as a cut flower and in landscaping but also as a source of natural carotenoid pigment, 'xanthophyll', used in poultry industries to intensify yelloworange colour of egg yolk, broiler skin and many other industries as it is free from health hazards, safe and eco-friendly in nature. Hence, marigold xanthophyll is gaining lot of importance in the international market. The study was conducted to identify a suitable, stable and high yielding genotype across the environments and standardization of production technologies for higher flower and xanthophyll yield in Alfisol at Floriculture Unit, Department of Horticulture, University .of Agricultural Sciences, Dharwad during kharif and rabi seasons of 2001- 02 and 2002-03. Fifteen genotypes of African and ten genotypes of French marigold were evaluated for phenotypic stability with respect to growth parameters, floral and xanthophyll yield. Among the African types, 'African Marigold Orange' (AMO) and 'Orange Boy' among French marigold recorded maximum number of branches, dry matter production, days to flower cessation, flower size, number of flowers per plant, flower, petal meal and xanthophyll yield per hectare, which were found to be stable and statistically superior over check Orange Double and Local Dwarf respectively. Nitrogen at 225 kg and phosphorus at 120 kg per hectare was found to be optimum dose for all the vegetative, floral, flower and xanthophyll yield per hectare during both the seasons, which was significantly superior over the lowest dose of N and P (175 kg N and 50 kg P/ha). Among the pinching and chemicals spray treatments, the pinched crop sprayed with DAP @ 2% recorded highest xanthophyll yield per hectare. However, the maximum flower yield was obtained due to pinching plus CCC @ 1000 ppm followed by pinching plus DAP @ 2%, which were found to be the best treatment combinations during both the seasons."

    PHOSPHORUS AND POTASSIUM MANAGEMENT UNDER INTENSIVE RICE CROPPING IN TUNGABHADRA (TBP) IRRIGATION COMMAND
    (University of Agricultural Sciences, Dharwad, 2003) HEBBARA, MANJUNATHA; PATIL, S G
    Field experiments were conducted to evaluate the effect of N, P and K levels under intensive rice-rice cropping system on crop performance, P-K availability, P-K uptake, P-K use efficiencies and P-K balance studies at Agriculture Research Station, Gangavati, Karnataka during 2000-01. Application of NPK @ 200:100:75 kg/ha (N:P:K ratio of 2.7:1.3:1.0) to BPT-5204 during kharif and 250:100:75 kg/ha (N:P:K ratio of 3.3:1.3:1.0) for IR-64 during rabi/summer was optimum and economically most remunerative. Though, higher NPK levels and ratios resulted in higher rice yields, the N:K ratios remained wider than the desired (< 2.0:1.0). The farmers control (230:90:110 kg/ha of NPK) was equally remunerative as above and had more balanced N:P:K ratio (2.1:0.8:1.0) than in the above treatments. The RDF application resulted in sub-optimal rice nutrition resulting in significantly lower yield than the above. Phased application of NPK up to BGF stage to a mid-long duration variety BPT-5204 was beneficial. However, this advantage was not realized during raMsummer with a mid duration variety like IR-64. The economic analysis also revealed similar trend. A tissue P of 0.33 per cent for BPT-5204 and 0.30 per cent for IR-64 at AT stage was optimum. Similarly, a tissue K of 1.37 per cent for BPT-5204 and 1.55 per cent for IR-64 at PI stage was found ideal. Fertilizer N:P and N:K ratios were significantly related to tissue P (at AT) and K (at PI) but not P.K ratio. Leaching losses of P and K were significantly higher under higher level of NPK fertilization and under only N splits compared to NPK splits. Leaching losses of P and K were also significant under farmers control over RDF application. The partial net P balance was positive with P application (RDP and beyond) during both the seasons. The partial net K balance was negative under RDK application (75 kg/ha K) during kharif and both RDK and 125 kg/ha of K application during rabi/summer. A higher fertilizer N:K ratio, coupled with negative K balances, especially at higher N rates, suggested unsustainability of such application practices on long term basis.
