This work investigated the effects of seven pollination bag treatments on three varieties of sorghum for: grain loss to birds; total weight of five panicles (g); total grain weight of five panicles (g); average grain weight per panicle (g); germination per cent; and occurrence of grain mold during 2016. Varieties were: 1167048 hybrid (brown seeded); BR007B (red seeded); and P9401 (white seeded). The bag treatments were: 1. No bagging; 2. Kraft paper; 3. Kraft paper + plastic bag screen; 4 Used duraweb® SG1; 5. Used duraweb® SG2; 6. New duraweb® SG1; 7. New duraweld® SG2. High bird pressure resulted in 100% seed loss on uncovered panicles and 75% under Kraft paper pollination bags. Birds preferred white seeded P9401, which led to no seed recovery under Kraft paper bags. There was virtually no bird damage with all other pollination bags. For panicle and grain yields the varieties performed in the order 1167048>BR007B>P9401. Unprotected panicles and paper bag treatments had the lowest yields. Panicles covered with the new synthetic bags exhibited 195 to 652% higher yields compared to Kraft paper bags. Varieties x bag type interactions were not important as they contributed 4 to 6% to the total sum of squares for yield traits. Germination test under normal and stress conditions showed no significant adverse effect of bag treatments on seed health. Reused bags performed as well as new bags for all of these traits. Varieties differed significantly for the occurrence of five grain mold pathogens, with highest occurrence of Alternaria, up to 40%, on 1167048 hybrid. Of the five pathogens, bag types differed significantly for Phoma with the highest occurrence of 9% on re-used duraweb®SG2 bags. Thus bags require disinfecting and cleaning before re-use. It is concluded that nonwoven synthetic bags are a better choice than the Kraft paper pollination bags for increasing the grain yield and virtually eliminating the bird damage in sorghum.

0 objetivo desse trabalho e descrever as caracteristicas gerais das propriedades de ovinos do Ceara. Para cumprir 0 objetivo, realizou-se uma pesquisa classificada quanto aos objetivos como descritiva e quanto a natureza ou abordagem do problema como qualitativa e quantitativa. Quanto ao delineamento o estudo caracterizou-se por uma ampla pesquisa de campo em 170 propriedades produtoras de ovinos no estado do Ceara. Estatisticas descritivas foram usadas na analise dos dados, com o uso do pacote estatistico SPSS. Esta analise descritiva permitiu a identificaçao dos sistemas de produçao caracterizados por propriedades com a maior parte da mao-de-obra familiar, caracterizando a logica produtiva da agricultura familiar; com acesso a energia eletrica e fonte permanente de agua elevado, embora o nivel de capitalizaçao seja baixo. Farms structure of sheep production in Ceará. Abstract - The objective of this paper is to analyze the prevailing farms structure of sheep production in the state of Ceará ? Brazil. This objective is achieved through a survey of 170 sheep farmers. Descriptive statistics was applied in the data analysis with the use of SPSS package. From the analysis, it was possible to identify that the farms are characterized by familiar labor, have access to electrical supply and permanent water, although the capitalization degree is low. |
