A field experiment conducted at Bio-fuel park, Agricultural Research Station, Madenur, Hassan in Kharif season of 2009 to asses the performance of finger millet (Eleusine coracana L.) under different organic manure treatment consisting of four treatments viz., recommended FYM and NPK through inorganic fertilizers as control, Pongamia, Mahua and Neem cake with 5 replications laid in randomized complete block design. The results revealed that application of recommended FYM along with neem cake equivalent to 100% recommended N performed better in respect of finger millet productivity and maintenance of soil fertility followed by recommended FYM with 100% NPK through fertilizers. Nutrient supplementation with different oilcakes proved superior in respect of soil sustainability.

:The simultaneous delivery of water and fertilizers to the active root zone through subsurface drip fertigation system ensures optimum growth of sugarcane. Field experiment was conducted at ZARS, V.C. Farm, Mandya during 2014-15 and 2015-16 seasons comprising of plant and ratoon cane, respectively. The investigation was conducted to know the performance of sugarcane as influenced by duration and levels of subsurface drip fertigation. Results revealed that fertigation duration upto 9.5 months recorded significantly higher growth parameters of plant and ratoon cane at harvest viz., plant height (330.6 and 296.2 cm), number of tillers m -1 (34.66 and 43.33), leaf area dm 2 m -1 (87.32 and 118.69), total dry matter production g plant -1 (652.57 and 466.91) and SPAD reading (34.67 and 37.72), respectively. Growth parameters significantly not influenced by fertigation levels. Whereas, the interaction between fertigation duration and levels were significant. Fertigation upto 9.5 months with 125 per cent RDF recorded significantly higher growth parameters viz., plant height (332.5 and 299.5 cm), number of tillers m -1 (34.97 and 43.98), leaf area dm 2 m -1 (89.27 and 121.63), total dry matter production g plant -1 (658.70 and 473.37) and SPAD reading (34.92 and 37.82) in plant and ratoon cane, respectively at harvest. Stastically, at par results were observed with fertigation upto 9.5 months with 100 per cent of RDF and fertigation upto 9.5 months with 75 per cent of RDF. Normal method of sugarcane cultivation with surface irrigation with 100 per cent RDF soil application recorded lower plant height (281.4 and 259.1 cm), number of tillers m -1 (29.2 and 38.15), leaf area dm 2 m -1 (57.34 and 84.38), total dry matter production g plant -1 (519.69 and 340.36) and SPAD reading (23.39 and 26.47). Thus, results clearly indicated that 25 per cent of the recommended dose of fertilizer could be saved with higher cane growth through sub surface drip fertigation (SSDF) over normal practice of sugarcane cultivation.Key Words : Sub surface drip fertigation, Fertigation duration, Fertigation levels, SPAD reading View Point Article : Padmanabhan, M., Nagaraju, Mohanraju, B. and Thimmegowda, M.N.

to assess the effect of row spacing, varieties and date of sowing on growth and yield of pigeonpea. Significantly higher growth parameters viz., plant height (165.4 cm), leaf area index (2.10), leaf area duration (60.34 days) and crop growth rate (2.39 g m -2 day -1 ) and yield parameters (grain: 940 kg ha -1 and stalk: 4089 kg ha -1 ) were recorded in narrow row spacing (60 cm) compared to wider row spacing (90 and 120 cm). The TTB-7 recorded significantly higher growth viz., plant height (163.6 cm), no. of branches per plant (10.4), total dry matter accumulation per plant (65.33 g), leaf area per plant (3429 cm -2 ), leaf area index (1.81), leaf area duration (50.97 days) and crop growth rate (2.33 g m -2 day -1 ) and yield (grain: 914 kg ha -1 and stalk: 3427 kg ha -1 ) compared to BRG-2 variety. Significantly recoded higher growth viz., plant height (185.2 cm), no. of branches per plant (10.7), total dry matter accumulation per plant (71.26 g), leaf area per plant (4030 cm -2 ), leaf area index (2.12), leaf area duration (57.23 days) and crop growth rate (2.66 g m -2 day -1 ) and yield (grain: 1149 kg ha -1 and stalk: 3721 kg ha -1 ) parameters in May had sown pigeonpea than June and July. Significantly higher grain yield (1284 kg ha -1 ) and stalk yield (4980 kg ha -1 ) was observed in narrow row spacing (60 cm) with TTB-7 variety at May month sown crop (S 1 V 1 D 1 ) which was on par with S
