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 demontration was carried out during Kharif 2016 in three villages of Tumkur district where 25 demonstrations on Pigeonpea crop were carried out in an area of 10 ha by the active participation of farmers with the objective to demonstrate the improved technologies in pigeonpea to exploit production potential. The improved technologies consisted of use of improved wilt resistant variety, seed treatment with Rhizobium culture, soil application Trichoderma and phosphate solubilising bacteria, balanced fertilizer application and integrated pest management. Frontline demonstrations (FLDs) recorded higher yield as compared to farmers’ local practice. The improved technology recorded higher yield of 10.5 q/ha compared to 8.25 q/ha in farmers’ local practice. In spite of increase in yield, technological gap, extension gap existed. The improved technology gave higher gross return, net return with higher benefit/cost ratio than farmers’ practices.Keywords
