The Relationship

The strong relationship between the late blight and climatic factors (namely temperature and rainfall)  has  important  consequences  on  potato  crops.  In  Romania,  in  early  spring  and  early  fall  the attack  degree  of  the  Phytophthora infestans  Mont.  de  Bary,  late  blight  pathogen,  is  low  because  in European  climate  average  temperature  is  not  more  than  10 0C,  and  usually  the  rainfall  supply  is reduced;  it  increases  in  late  spring  and  summer  when  average  temperatures  are  around  20 0C  and rainfall average more that 65 mm/month. The aim of this paper is to describe the relationship between temperature, rainfall regimen and late blight attack degree in potato cultures. The research was carried on  during  two  years,  2009  and  2010,  in  three  experimental  fields  from  Transylvania:  Răhău,  Alba; Maieru,  BistriÅ£a-Năsăud;  Draguș,  Brașov.  Classical  methodology  was  used  for  monitoring.  The  data were statistically processed using STATISTICA  v. 7.0 programme. The interrelation attack degree - abiotic  factors  reflects  a  maximum  intensity  of  the Phytophthora infestans  Mont.  de  Bary  attack degree by the entire year 2009 around 42 % recorded when the rainfall average values begin with 110 mm  and  thermic  conditions  correspondent  to  values  bigger  than  20 0C.  In  the  year  2010  the multiregression  analyze  of  the  monitored  interactions,  led  to  a  very  strong  multiple  correlation coefficient  of  0.938  representative  in  share  of  87.90%.  In  2010,  by  the  entire  monitored  period,  the rainfall supply had a bigger influence on the attack degree compared to thermic conditions. In 2009, the predicted biggest recorded attack degree of Phytophthora infestans de Bary was of 44% while in 2010 it was of 40 %, correspondent to rainfall and temperature regimens.

ABSTRACT: This study aimed to investigate factors influencing the adoption of improved cultivars (ICs) in peach production in Khyber Pakhtunkhwa province of Pakistan. A total of 270 respondents were randomly selected from the three different cultivated areas of Khyber Pakhtunkhwa, namely, Peshawar, Nowshera and Swat. Binary choice model was used in this study to categorise the ICs of peach farmers into adoption and non-adoption. The study identifies that socio-economic, institutional farm resources, and climatic factors are influencing the adoption of ICs of peach production. Results of the estimated model reveal that farmer’s age, education, household size, membership, cell phone, farm size, extension services and the role of the non-government organization have a positive effect on adoption of ICs. In addition, farmer’s experience, off-farm income, livestock and machinery ownership, credit access and inputs prices have a positive and significant impact on ICs adoption. Moreover, results of the logit model demonstrate that climatic related factors have a highly significant and positive impact on the adoption of ICs. These results suggested that institutional services should be strengthened to provide managerial and technical skills on ICs technology adoption and on time provision of financial services to enhance the productivity of peach farmers.

Factors Influencing

Most herbicides are applied preemergence onto bare soil or during the early stage of plant development. Therefore, the major part of the active ingredient either reaches the soil surface immediately or later with decaying plant material. The further fate of the herbicide depends largely on the physicochemical behavior of the respective compound, the amount and method of application, and a number of soil, plant, and climatic factors influencing the persistence and bio availability of organic compounds in a given soil (5, 7). Especially in the upper 2-cm soil layer, drastic changes in temperature and moisture content during a growing season have a great influence on the degradation and adsorption of herbicides in soil (10, 31).
