A field experiment was conducted to find out the effects of different levels of pant spacing and fertilizer dose on growth and bulb yield in tuberose (Polianthes tuberosa L.). The experiment consisted of twelve treatment combinations, comprising of three different plant spacing (S1-45×30 cm, S2-30×30 cm and S3-30×15 cm), four levels of fertilizers doses such as F0-Only FYM (25t/ha), F1-200:200:200 kg NPK/ha+FYM (25t/ha), F2-250:250:250 kg NPK/ha+FYM (25t/ha) and F3-300:300:300 kg NPK/ha+FYM (25t/ha) with four replications and Factorial in a Randomized Complete Block Design (RCBD). The result of field experiments revealed that the significant difference on growth and bulb parameters as affected by different plant spacing and fertilizers levels. The plant spacing of 30×30 cm with fertilizers levels of 250:250:250 kg NPK/ha+FYM (25t/ha) were found to be optimum for better growth and recorded significant maximum plant height (55.26cm), number of leaves per plant (115.74), number of side shoots per pant (22.64) and early sprouting of bulbs (10.85days) as compared to control (45×30 cm spacing with application of FYM 25 t/ha only) in interaction. Whereas, bulb parameters recorded significant increase in size of mother bulb (4.97 cm), size of daughter bulbs (4.19 cm), numbers of bulbs per plant (18.01), number of bulblets per plant (15.02) and clump weight (515.15 g) at 45×30 cm spacing with fertilizer level 250:250:250 kg NPK/ha+FYM (25 t/ha) as compared to control. Cultivation of tuberose at 45×30 cm plant spacing with the application of fertilizer dosage at 250:250:250 kg NPK/ha+FYM (25 t/ha) can be recommended to obtain superior quality bulbs and bulblets.Keywords

The studies were conducted on effect of integrated crop management on brinjal yield and economics through frontline demonstration at farmers field of Tumkuru district, Karnataka state during the year 2009-10 to 2011-12. The data revealed that the total yield gap between potential yield and actual yield of brinjal was 53.67 per cent, in which 16.92 per cent of yield gap between demonstration plot and actual farmers plot yield and 36.75 per cent of technological gap. The maximum number of farmers were adopted recommended spacing (88.33%) followed by seed treatment (83.33%), timely irrigation (81.67%) and weed management (81.67%). The increased in adoption level of package of practices were found to more in raising and selection of quality seedling from nursery (50.00%) fallowed by selection of high yielding hybrid variety (46.67%) and application of vegetable special (50.00%). Whereas, the package of practices viz., plant protection measures to control pest and diseases (21.67%), application of recommended dose of fertilizer (25.00%) and seed treatment (26.67%) were found to less increase in adoption level after frontline demonstration. There was significantly increased in brinjal yield (36.51%), net return and B:C ratio after conduct of frontline demonstrations as compared to farmers practice. The adoption of package of practices even though after demonstrations programme, which shows positive impact of integrated crop management on brinjal yield and economics through adoption of demonstrated technology.Keywords
