A field study on the effects of pre- and post-emergence application herbicide (pendimethalin) reproductive yield five accessions cowpea (TVu-9092, TVu-16265, TVu-16320, TVu-16323 TVu-16421) was conducted between June August, 2018. Pendimethalin applied both as early (PE EPOE) followed by hand weeding at 4 8 weeks after sowing (WAS). Number pods per plant highest in TVu-9092 treated with 0.125 k...

Background: Groundnut or peanut (Arachis hypogaea L.) is known as the ‘king’ of oilseeds. It one most important food and cash crop India. Among different constraints that limit productivity groundnut, weed menace serious bottlenecks. A field experiment was conducted at Perunthalaivar Kamaraj Krishi Vigyan Kendra, Puducherry during 2019 to 2020 study tank mix application post-emergence herbicide...

Flaxleaf fleabane is a difficult-to-control weed in dryland minimum tillage farming systems in the northeast grains region of Australia. Experiments were conducted between 2003 and 2005 to identify effective control strategies on flaxleaf fleabane in wheat and sorghum. A preplant application of chlorsulfuron at 15 g ai/ha in wheat controlled flaxleaf fleabane $ 90%. The efficacy of early postem...

A field study was carried out during the rainy (kharif) season of 2019–20 at ICAR-Indian Agricultural Research Institute, New Delhi, to effect nitrogen and weed management practices in dry direct-seeded rice (Oryza sativa L.) for obtaining higher productivity crop growth. The experiment laid a split-plot design, taking 3 treatments, i.e. No N (P K only), recommended dose fertilizer (RDF–N : P =...

Cerotoma trifurcata Förster (Coleoptera: Chrysomelidae) and Bean pod mottle virus (Comoviridae) (BPMV) both can reduce yield and seed quality of soybean, Glycine max (L.) Merr. Field experiments were conducted to evaluate the effects of systemic, seed-applied, and foliar-applied insecticides for the management of this pest complex at three locations in central, northeastern, and northwestern Io...

Background and Aims: Hemagglutinin (HA) protein of Avian Influenza (AI) plays an essential role in the virus pathogenicity. AI H9N2 subtype causes significant economic loss in broiler and layer in poultry farms in Iran. AI viruses have a great involvement in evolutionary changes at nucleotide and amino acid levels and vaccines could induce faster rates of such changes. Up-dated understanding of...
