    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-08-06) RAGHAVENDRA, N.; SANJAY, M. T.
    A field experiment entitled “Bio-efficacy and phytotoxicity of new herbicide molecules for effective weed management in direct seeded rice (Oryza sativa L.)” was conducted at the Main Research Station, University of Agricultural Sciences, Hebbal, Bengaluru, during Kharif 2018. Nine herbicide treatments including four new herbicide molecules (carfentrazone, ethoxysulfuron, penoxsulam + cyhalofop and triafamone + ethoxysulfuron) at 15 DAS, bispyribac sodium at 15 DAS, pyrazosulfuron, oxadiargyl, bensulfuron methyl + pretilachlor, pendimethalin at 3 DAS, passing cycle weeder followed by hand weeding at 20 and 35 DAS and unweeded control were replicated thrice in RCBD. Major weeds observed were Cyperus rotundus, Cynodon dactylon, Dactyloctenium aegyptium, Ageratum conyzoides, Borreria articularis, Commelina benghalensis. Post emergence application of triafamone + ethoxysulfuron 30% WG (RM) 60 g a.i./ha at 15 DAS fb passing cycle weeder and hand weeding at 35 DAS recorded significantly higher rice grain yield, net returns and B:C ratio (5491 kg ha-1 , Rs. 59,240 ha-1 and 2.58, respectively) and was on par with passing cycle weeder followed by hand weeding at 20 and 35 DAS (5618 kg ha-1 , Rs. 57,434 ha-1 and 2.39, respectively) followed by bensulfuron methyl + pretilachlor 6.6% G 660 g a.i./ha within 3 DAS fb passing cycle weeder and hand weeding at 30 DAS (5122 kg ha-1 , Rs. 54163 ha-1 and 2.47, respectively) without any phytotoxicity on direct seeded rice. Unweeded control recorded significantly lower rice grain yield, net returns and B:C ratio (1400 kg ha -1 , Rs.- 1084 ha -1 , 0.96, respectively) and higher weed index (75.08%) compared to other treatments.

    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-07-30) YATHISHA, K. P.
    A field experiment was conducted during Kharif-2018 at Zonal Agricultural Research Station, V. C. Farm, Mandya. The experiment was laid out in RCBD emphasizing nine treatments and replicated thrice. The treatments were consisting of five pre-emergence herbicides (Atrazine, oxadiargyl, bensulfuron methyl + pretilachlor, pendimethalin and isoproturon), two post-emergence herbicides (Bispyribac sodium and ethoxysulfuron), hand weeding at 20 and 35 DAS and weedy check. Major weeds observed were Cyperus rotundus, Cynodon dactylon, Eleusine indica, Ageratum conyzoides, Parthenium hysterophorus and Commelina benghalensis. Among different herbicides, pre-emergence application of bensulfuron methyl + pretilachlor 6.6% G at 198 g a.i. ha-1 + hand weeding at 30 DAS recorded lower total weed density, weed dry weight, weed index and higher weed control efficiency (29.0 m-2, 15.65 g m-2, 84.0% and 91.57%, respectively) and registered significantly higher grain (3345 kg ha-1) and straw yield (4905 kg ha-1), which may be attributed to significantly higher plant height (97.3 cm), number of tillers (39.3 m-1) and total dry weight of plant (67.8 g hill-1) at harvest. The same treatment shown higher yield attributing characters viz., number of productive tillers (37.4 m-1), finger length (9.9 cm) and grain yield per plant (25.30 g) and this treatment also resulted in higher net returns (` 46,907 ha-1) and B:C ratio (2.48) and found to be most economical and comparable with the treatment intercultivation and hand weeding at 20 and 35 DAS in direct seeded finger millet.
