    AN ECONOMIC ANALYSIS OF SILK REELING UNITS IN KARNATAKA
    (University of Agricultural Sciences, Dharwad, 1999) KERUTAGI, M G; RANGANATHA SASTRY, K N
    "Karnataka is leading in mulberry silk production. The focus of the study was on economic analysis of silk reeling units. Multistage sampling procedure was adopted and totally 250 samples were selected. Relevant data collected from primary' and secondary sources were analysed through tabular, cluster, orthogonal polynomial regression, log-linear regression, frontier function and decomposition techniques. The growth analysis of charka and cottage basins in Karnataka showed an increasing trend upto 1996, then onwards showed a declining trend. Charka and cottage basins in Bangalore and Kolar districts exhibited constant increasing trend. Mysore district showed a unique pattern of declining trend in the later part of 1990s. Renditta was 8.82, 9.57 and 9.02 kg in charka, cottage and multi-end basins respectively. The share of cocoon cost to the total cost was 85 percent in these systems. Sources of fuel used in reeling were neither eco-friendly nor cost-effective. Net returns per kg of silk reeled were Rs.47,21, Rs. 146.18 and Rs. 185.28 in these systems, respectively. Medium charkas (4-5/unit) and cottage basins (6-8/unit) were found optimum. The proportion of women labour used was more in all the systems. Labour employed per kg of silk reeled was 1.07, 1.45 and 1.34 man-days in charka, cottage and multi-end basins, respectively. The value addition (72.18%) in cottage basin reeUng over charkas was mainly due to technique of reeling (57.56%) and the remaining attributed for the use of inputs (14.62%). The package for introduction of silk reeling in new sericulture area suffers from lack of skilled labour, infrastructure, financial support and correct information about the programmes. The conditions under which children worked were most pathetic. Present laws and their efficiency of implementation have not solved the problem of child and women labour exploitation, hence needs the thorough investigation."

    PHOSPHORUS DYNAMICS IN VERTISOLS UNDER SUNFLOWER - MAIZE - BENGALGRAM CROPPING SEQUENCE
    (University of Agricultural Sciences, Dharwad, 1999) BHAT, SHREEPAD; DODDAMANI, V S
    An investigation was carried out to know the effect of single superphosphate (SSP), Mussoori rock phosphate (MRP), 25 percent acidulated rock phosphate (PARP) and their combination and P solubilizers viz. FYM, pyrite and P solubilizing microorganisms (PSM) on P transformation, available P, crop yield under sunflower-maize-bengalgram cropping sequence in Verlisols of Water Management Research Centre, Belavatagi, during 1996-97 and 1997-98. Asi incubation study with 28 treatment combinations was also conducted to assess the extent of release of P with time. Results of incubation study revealed that recovery of P from SSP and SSP + PARP at 30,60 and 90 days was 11.1,11.3 and 11.2 and 9.2,8.3 and 9.1 percent, respectively Recovery of P from MRP at the corresponding period was 1.6,1.4 and 4.4 percent. Incorporation of FYM increased available P followed by pynte and PSM at 30 days of Incubation. Available P at harvest of 3 crops with SSP was higher. At harvest of second and third crop, MRP recorded 9.0 and 30 0 percent higher available P over P control. Available P due to solubilizers was in the order of FYM>Pyrite>PSM>control. Yield of sunflower did not differ due to P sources and solubilizers. The highest (27.07q/ha) and lowest (24.42 q/ha) yield of maize was registered with SSP and MRP, respectively. The yield of bengalgram was also the highest (16.74 o/ha) due to residual effect of SSP and was on pay with p sources except MRP and P control. Among the solubilizers higher grain yield of crops was observed with FYM followed by pynte and PSM. The Ca-P was higher in MRP and FARP; and with their combination with other P sources and was because of di and tri-calcium, phosphate present in MRP and less solubility of Ca-P in alkaline sods. SSP and its combination with other P sources increased Al-P and Fe-R which are well correlated with yield of crops. On the basis of crop yield available P it is inferred that the next best alternative treatment for increased crop yield and available P was SSP + PARP.

    NUTRITIONAL AND PROCESSING QUALITIES OF DICOCCUM (Triticum dicoccum Schrank, Suhulb) WHEAT VARIETIES
    (University of Agricultural Sciences, Dharwad, 1999) BHUVANESWARI, G; YENAGI, NIRMALA B
    Interest towards utilization of hulled dicoccum wheat has been increased in agriculture due to the low input techniques used for their management. Since quality is the most important criterion in the promotion of dicoccum wheat genotypes, eight dicoccum wheat varieties along with one each check varieties of durum and bread wheat were studied for nutritional, technological and therapeutic qualities for gainful utilization. Physico-chemical, carbohydrate profile, in-vitro protein and carbohydrate digestibility were analyzed by standard procedures. Fractionation of gluten and gliadin proteins was carried out by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Varieties were also evaluated for milling, vulgarisation, popping, baking, pasta making and extrusion qualities. Glyce mic index of dahlia and semolina of commercially available dicoccum wheat, DDK-1001 was determined to assess the therapeutic quality. Visual observation revealed that almost all the dicoccum wheats were reddish in colour and elongated with pointed ends. Thousand Kernel Weight of dicoccum wheats was lower than durum wheat. The hardness values of dicoccum wheats were ranged from 3.19 to 6.60 kg/grain.Nutritionally, dicoccum wheats were rich in protein, total sugar and dietary fibre contents and good source of ash and B-carotene contents. Dietary fibre and low carbohydrate digestibility were the contributing factors for low glycemic index of dicoccum wheat products. Good semolina milling potential of dicoccum wheats and good cooking qualities were found to be highly suitable for preparation of pasta products and extnidates. y-45 gliadin band was the contributing factor for better pasta quality. Dicoccum wheats also showed a good popping quality. Bulgurisation was the most suitable processing method for dicoccum wheats as it improved the milling, popping and cooking qualities. Dicoccum wheats showed potential for bread making quality due to the presence of l', 1 and 7+8 glutenin bands. Nutritionally superior and good processing potential dicoccum wheat varieties were DDK-IOOL DDK-1016, DDK-1009, NP-200 and 278-13.
