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

A field experiment was carried out during kharif 2013, 2014, 2015 and 2016 at Zonal Agricultural Research Station, V. C. Farm, Mandya to study the performance of cowpea under organic production system in red sandy loam soil. The results revealed that application of 100% N equivalent compost + recommended FYM (10 t/ha) + beejamrutha (seed treatment) + jeevamrutha (500 liter/ha) recorded significantly higher grain yield during all the years of experimentation (2056, 1987, 2108 and 2365 kg/ha, respectively) and also in their pooled data (grain yield 2129 kg/ha). This increased yield was attributed to more availability of nitrogen (289.5 kg/ha), phosphorus (40.5 kg/ha) and potassium (182.3 kg/ha) in the soil compared to other treatments. The benefit: cost ratio was higher with application of 100% N equivalent compost + jeevamrutha + beejamrutha (2.81). Soil chemical properties, viz. soil pH, organic carbon content and electric conductivity, were not influenced significantly by application of organic manures. However, there was an improvement in the soil chemical properties (289.5, 40.5 and 182.3 N, P 2 O 5 and K 2 O kg/ha, respectively) compared to initial soil data (229, 19.2 and 135 NPK kg/ha).

Field experiment was conducted during rainy seasons of 2014 and 2015 to study the effect on weed management practices in wet direct-seeded rice (Oryza sativa L.) in Cauvery command area of Karnataka under irrigated condition with eight treatments replicated thrice. Pre-emergence application of bensulfuron-methyl + pretilachlor GR (Londax Power) at 660 g/ha fb bispyribac-sodium (Nominee Gold) at 25 g/ha at 20 days after sowing (DAS) significantly reduced weed growth and recorded the higher seed yield (4.80 t/ha), net monetary returns (` 25631/ha) and B:C ratio (1.62) and it was at par with other sequential treatments, viz. pre-emergence application of pendimethalin at 1.0 kg/ha (Stomp) fb postemergence application of bispyribac-sodium, pre-emergence application of bensulfuron-methyl + pretilachlor, application of pendimethalin as pre-emergence fb 1 HW. Uncontrolled weed growth caused 55.2% reduction in seed yield of wet seeded rice.
