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."ThesisItem Open Access PHOSPHORUS DYNAMICS IN VERTISOLS UNDER SUNFLOWER - MAIZE - BENGALGRAM CROPPING SEQUENCE(University of Agricultural Sciences, Dharwad, 1999) BHAT, SHREEPAD; DODDAMANI, V SAn 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.
