Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The research work was carried out with two broad objectives. Firstly to screen most efficient high yielding disease resistance variety and secondly to manage the disease with less hazardous and useful fungicides for the benefits of farmers. Potato (Solanum tuberosum L.) is one of the most important food and cash crop . In Assam, it is grown in an area of 7.78 thousand ha producing 584 thousand ton with an average productivity of 75.71 q/ha (Gupta et al., 2009) which is very low as compared to national productivity level (187.7 q/ha). The various factors limiting yield of the crop include lack of HYV, inadequate supply of healthy seed tubers, highly dependence of rain fed cultivation and high incidence of disease and pest. Among the diseases late blight of potato incited by Phytophthora infestans (Mont) de Bary is the most destructive disease. In Assam the diseae ocuurs in epidemic form .Among the potato varieties, Kufri Megha, Kufri Jyoti, Kufri Pukhraj have been grown popularly in the state. But almost all cultivable varieties within the species Solanum tuberosum L are susceptible.Considering the economic importance of the disease present study was conducted.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Les travaux de recherche ont été menés avec deux objectifs principaux. Premièrement, sélectionner les variétés les plus efficaces, à haut rendement et résistantes aux maladies. Deuxièmement, lutter contre la maladie à l'aide de fongicides moins dangereux et plus efficaces, dans l'intérêt des agriculteurs. La pomme de terre (Solanum tuberosum L.) est l'une des cultures vivrières et commerciales les plus importantes. En Assam, elle est cultivée sur une superficie de 7 780 ha et produit 584 000 tonnes, avec un rendement moyen de 75,71 q/ha (Gupta et al., 2009), ce qui est très faible par rapport au niveau national (187,7 q/ha). Les différents facteurs qui limitent le rendement de cette culture sont notamment l'absence de variétés à haut rendement, l'approvisionnement insuffisant en semences saines, la forte dépendance à l'égard de l'agriculture pluviale et la forte incidence des maladies et des ravageurs. Parmi les maladies, le mildiou de la pomme de terre, provoqué par Phytophthora infestans (Mont) de Bary, est la plus destructrice. En Assam, la maladie se présente sous forme épidémique. Parmi les variétés de pommes de terre, Kufri Megha, Kufri Jyoti et Kufri Pukhraj sont les plus cultivées dans l'État. Cependant, presque toutes les variétés cultivables de l'espèce Solanum tuberosum L sont sensibles. Compte tenu de l'importance économique de la maladie, la présente étude a été menée.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Badania przeprowadzono w dwóch g¿ównych celach. Po pierwsze, w celu wyselekcjonowania najbardziej wydajnych odmian odpornych na choroby, a po drugie, w celu zwalczania chorób przy u¿yciu mniej szkodliwych i bardziej skutecznych fungicydów, z korzy¿ci¿ dla rolników. Ziemniak (Solanum tuberosum L.) jest jedn¿ z najwäniejszych ro¿lin spo¿ywczych i uprawianych dla zysku. W stanie Assam uprawia si¿ go na obszarze 7,78 tys. ha, uzyskuj¿c plony w wysoko¿ci 584 tys. ton, przy ¿redniej wydajno¿ci 75,71 q/ha (Gupta et al., 2009), co jest wynikiem bardzo niskim w porównaniu z krajowym poziomem wydajno¿ci (187,7 q/ha). Ró¿norodne czynniki ograniczaj¿ce plony tej uprawy to brak wysokowydajnych odmian, niewystarczaj¿ca podä zdrowych bulw nasiennych, du¿a zale¿no¿¿ od upraw deszczowych oraz wysoka cz¿sto¿¿ wyst¿powania chorób i szkodników. W¿ród chorób ziemniaka najbardziej niszcz¿c¿ jest zaraza ziemniaczana wywo¿ywana przez Phytophthora infestans (Mont) de Bary. W stanie Assam choroba wyst¿puje w formie epidemii. W¿ród odmian ziemniaków popularne s¿ odmiany Kufri Megha, Kufri Jyoti i Kufri Pukhraj. Jednak prawie wszystkie odmiany uprawne w obr¿bie gatunku Solanum tuberosum L s¿ podatne na t¿ chorob¿. Bior¿c pod uwag¿ znaczenie gospodarcze tej choroby, przeprowadzono niniejsze badanie.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - O trabalho de investigação foi realizado com dois objetivos gerais. Em primeiro lugar, selecionar a variedade mais eficiente, de alto rendimento e resistente a doenças e, em segundo lugar, controlar a doença com fungicidas menos perigosos e mais úteis, para benefício dos agricultores. A batata (Solanum tuberosum L.) é um dos alimentos e culturas comerciais mais importantes. Em Assam, é cultivada numa área de 7,78 mil hectares, produzindo 584 mil toneladas, com uma produtividade média de 75,71 q/ha (Gupta et al., 2009), o que é muito baixo em comparação com o nível de produtividade nacional (187,7 q/ha). Os vários fatores que limitam o rendimento da cultura incluem a falta de HYV, o fornecimento inadequado de tubérculos saudáveis, a elevada dependência da cultura de sequeiro e a elevada incidência de doenças e pragas. Entre as doenças, a requeima da batata, provocada por Phytophthora infestans (Mont) de Bary, é a mais destrutiva. Em Assam, a doença ocorre de forma epidémica. Entre as variedades de batata, Kufri Megha, Kufri Jyoti e Kufri Pukhraj são as mais cultivadas no estado. No entanto, quase todas as variedades cultiváveis da espécie Solanum tuberosum L são suscetíveis. Considerando a importância económica da doença, foi realizado o presente estudo.…
