ABSTRACT Pineapple mealybug wilt has been reported as one of the most important diseases affecting pineapple crops worldwide. This study aimed to determine prevalence mealybugs associated with two agroclimatic zones production in department Valle del Cauca, Colombia. The survey was conducted upper (Dagua, Restrepo, La Cumbre and Vijes) lower (Buga Palmira) land zones. A total 75 MD2 plots diffe...

To quantify the effect of meteorological parameters on incidence Karnal bunt in wheat crop, an investigation was done using 9 to 12 season’s data Bathinda and Ludhiana stations Punjab. Maximum temperature during March range 25-31oC, minimum February (8.5-11.0oC), morning evening relative humidity 85-95 40-60 per cent respectively, rainfall more than 25 mm with sunshine hours 5.5-9.0 hrs/day mid...

Global climate change is likely to influence evapotranspiration (ET); as a result, many ET calculation methods may not give accurate results under different climatic conditions. The main objective of this study verify the suitability machine learning (ML) models for pan evaporation modeling on macro-regional scale. most significant PE changes in agroclimatic zones Slovak Republic were compared,...

The agricultural sector in Poland is of considerable social and economic importance for the nation. Climate variability and change are of primary relevance to this largely climate-dependent sector. Changes in seven temperature-related agroclimatic indices (lengths of the growing season and of the frost-free season, days of occurrence of the last spring frost and of the first autumn frost; and a...

Comparative assessment of the mitochondrial cytochrome oxidase I (mtCOI) gene sequence uncovers Bemisia tabaci mitotypes. The current study aims to define B. mitotypes found in various agro ecological zones across India. Phylogenetic analysis 13 samples from agroclimatic regions revealed presence four mitotypes: Asia 1, II 5 and 7. Among, 1 was be abundant widespread distribution thirteen locat...

The objective of this research is to compare the chemical profiles essential oils Lippia origanoides leaves collected in Santa Marta and Sincelejo at different hours. were harvested 6:00 a.m., 12:00 p.m, extracted by hydrodistillation assisted microwave radiation determined gas chromatography coupled mass spectrometry. results showed Thymol as major metabolite all samples, however, presented hi...

the zoning of phenomena based on geographical location has a long history; any geographical zone is a part on ground level, which possesses noticeable internal consistency in terms of its existing phenomena and processes. agroclimatic zoning is mainly purposed to determine agroclimate regions and to evaluate these zones based on their relative utility in order to cultivate varieties of agricult...
