A field experiment was conducted during Kharif season of 2015 & 2016 at Krishi Vignana Kendra Haradanahalli, Chamarajanagara, Karnataka to study the efficacy of herbicide for controlling weeds in hybrid Cotton. The trial was comprised of three herbicides viz., pendimethalin (38.75 EC) at 0.75 kg a.i.ha -1 , Tank mixture of pyrithiobac sodium (10 SC) @ 62.5 g a.i.ha -1 + quizolofop ethyl (5 EC) @ 37.5 g a.i.ha -1 , pendimethalin (38.75 EC) @ 0.75 kg a.i.ha -1 , followed by Glyphosate (41% SL) @ 1.0 kg a.i.ha -1 , were compared with weed free and weedy check and laid out in randomized complete block design and replicated four times. The results revealed that, tank mixture of pyrithiobac sodium (10 SC) @ 62.5 g a.i.ha -1 + quizolofop ethyl (5 EC) @ 37.5 g a.i.ha -1 at 2 to 4 leaf stages of weeds recorded higher weed index (16.6%), net monetary returns (48500/-Rs./ha) and returns per rupees spent (Rs.12.54) with kapas yield of 1702 Kg/ha as compare to other herbicides.

A field experiment was conducted at zonal agricultural research station, V. C farm, mandya during summer 2019 to study the response of multi-cut pearl millet genotypes to varied levels of nitrogen and to identify the optimum and economical level for higher green forage yield and quality. The study revealed that, the variety Giant bajra national check recorded significantly higher green forage and dry matter yield (608.0 and 114.9 q ha -1 respectively), net monetary returns (Rs.56,346 ha -1 ) and agronomic efficiency of nitrogen (632.0 Kg green fodder yield per Kg of N). However the variety HTBH-4902 recorded significantly higher crude protein yield (9.13 q ha -1 ) and it was on par with variety Giant bajra (8.72 q ha -1 ). Application of 120 kg N ha -1 significantly recorded higher green forage, dry matter and crude protein yield (741.1 q, 143.4 q and 12.57 q ha -1 respectively) and net monetary returns (Rs.72,234 ha -1 ). The application of nitrogen at 40 Kg per hectare recorded higher agronomic efficiency of nitrogen (542.0 Kg green fodder yield per Kg of N).

To study the bio-efficacy of selected insecticides against earhead caterpillars in finger millet (variety KMR-204) under field conditions an experiment was conducted at Zonal Agricultural Research Station Vishweshwaraiah Canal, Farm, Mandya, during kharif 2018 and 2019, University of Agricultural Sciences, Bangalore. The results revealed that, two sprays at dough stage of the crop, all the insecticides viz., thiodicarb 76 WP (1.0 g L -1 ), acephate 75 SP (1.5 g L -1 ), profenphos 50 EC (2.0 mL L -1 ), quinalphos 25 EC (2.0 mL L -1 ), lambda cyhalothrin 5 EC (0.6 mL L -1 ), novuluron 10 EC (1.5 mL L -1 ), fenvelarate 0.4D (25 kg ha -1 ), chlorpyriphos 1.5D (25 kg ha -1 ) and chlorpyriphos 20 EC (2.0 mL L -1 ) were found to be effective in reducing different species of earhead caterpillars viz., Archips micaceana, Somena scintillans, Cryptoblabes angustipennella, Nola analis, Cydia sp., Helicoverpa armigera, Pyrausta phoenicealis, Corcyra cephalonica, Stathmopoda sp. and Spodoptera frugiperda, Eublemma sp., Conogethes punctiferalis, Euproctis similis, Mythimna separate and Ataboruza sp., over untreated control. However, thiodicarb 75 WP @ 1.0 g L -1 and lambda cyhalothrin 5 EC at 0.6 mL L -1 were found to be more effective in reducing the mean larval population and registered higher percentage of recovery with least larval population compared to rest of the insecticides.
