ThesisItem Open Access Evaluation of pinoxaden in combination with 2, 4-D against complex weed flora in barley(CCSHAU, 2010) Sunil Kumar; Bhattoo, M.S.A field experiment was conducted during rabi 2008-09 at Cotton Research Station, Sirsa of Chaudhary Charan Singh Haryana Agricultural University, Hisar to evaluate the efficacy of pinoxaden as tank mixture or sequential application with broad leaf herbicide 2, 4-D for controlling the complex weed flora in barley. All the weed control treatments effectively controlled the weeds and gave significantly higher grain yield than the weedy check. Post-emergence application of pinoxaden at 40, 45 and 50 g ha-1 alone provided excellent control of P.minor Retz. and A. ludoviciana Dur., whereas 2, 4-D at 500 g ha-1 proved very effective against all broadleaf weeds. Application of pinoxaden 40, 45 and 50 g ha-1 and 2, 4-D either as tank mixture or their application in sequence before or after one week interval effectively controlled the complex weed flora without any phytotoxic effect on crop and produced grain yield of barley equal to weed free treatment. No antagonism between pinoxaden and 2, 4-D was observed as shown by percent control of grassy weeds.ThesisItem Open Access Characterization of elite forage cowpea genotypes for DUS traits(CCSHAU, 2012) Sunil Kumar; Phogat, D.S.The objective of present investigation was to for characterize twenty genotypes of cowpea {Vigna unguiculata (L.) walp.} on the basis of morphological characters provided by IITA, Ibadan, Nigeria for DUS testing in cowpea. Results revealed that maximum variation was found among genotypes on the basis of eye colour in which genotypes IC249141, GFC-4, GFC-3, COFC8 had black and blue, CO4 had speckling, EC3941-1 had tan and brown, EC101980 and Kohinoor had red and remaining twelve genotypes had white, cream, brown splash and gray colour group. Whereas, eye pattern varied from Watson group (seven genotypes), holstein group (three genotypes), small eye group (four genotypes), narrow eye (three genotypes) to kappa group (three genotypes). On the basis of plant growth habit four groups were made acute (two genotypes), erect (nine genotypes), semi-erect(four genotypes) and semi-prostrate (five genotypes).On the basis of extent of seed crowding genotypes had four groups had extreme crowder (three genotypes), crowder (four genotypes), semi-crowder (genotype IC249141) and non-crowder (eleven genotypes). On the basis of twining tendency the genotypes were divided in three groups none (five genotypes), moderate (fourteen genotypes), pronounced (genotype CO5). Whereas, shape of terminal leaflet varied from very globose (genotype Kohinoor), sub-globose (five genotypes) to globose (fourteen genotypes). On the basis of pod attachment to peduncle the genotypes were divided into three groups, two genotypes HC-46 and CO(CP)-7 were erect, seventeen genotypes were attached at angle of 30 to 90 degree and the genotype EC101980 was pendant. On the basis of seed length genotypes were divided into three groups, very short(three genotypes), short (thirteen genotypes) and intermediate (three genotypes). On the basis of seed thickness genotypes were divided into three categories, genotypes CS88 and Kohinoor were thick, three genotypes were flat, fifteen genotypes were very-flat. Classification of genotypes on the basis of DUS traits provided identification of key characteristics of various genotypes.
