India is the fourth largest oilseed producing country in the world. The present study was carried on based on the secondary data collected from varies websites and directorate of economics and statistics. The results reveled that the compound growth rate of area and production of groundnut in India shows a negative trend while the productivity was positive over the years. In pre bifurcated Andhra Pradesh the annual average production of groundnut during 2011-12 was 1231 thousand tons and the annual average yield per hectare was 873 kg/ha. The area and production of groundnut was high in Rayalaseema region compared to other regions of the state.The area, production and productivity of groundnut in Mahabubnagar district of Telangana was increase over the study year. The annual average production of groundnut crop during 2013-14 was 220 thousand tonnes and annual average yield per hectare during the same period was 1751 kg/ha.

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.
