Weather parameters

We tracked yearly variation in breeding phenology in relation to weather parameters in a common European toad population from the southeastern part of its range. Phenological data were collected from 2001 to 2003 and from 2011 to 2017 and compared to open-access daily weather data from a nearby weather station. Data analysis revealed no significant effect of weather on initiation of breeding and a negative relationship between mean daily humidity and mean cloud cover on the duration of breeding season (P = 0.03).

Outdoor regional concentrations of airborne fungal spores and fungal fragments were measured using the 7-day Lanzoni sampler. The daily and intradiurnal fluctuations recorded during the monitored period have been studied. The multiple regression analysis was performed in order to determine how much of the total variance in these concentrations could be explained by meteorological parameters. Daytime periodicity (statistically significant) was established only in a few cases. As the relative importance of the weather factors varied, they could not be ranked according to their effect.

Banana (Musa spp.) is one of the most important commercial fruit crops especially in the tropics. Of the many diseases occurring on banana, sigatoka leaf spot disease incited by Mycosphaerella musicola Leach, is considered as serious threat to world banana production. Given the importance of yellow Sigatoka in banana plantations and lack of information on its epidemiology, the present study was conducted to assess the incidence of Sigatoka leaf spot in banana plants cultivated through organics manures and inorganic fertilizer.

Weather is considered crucial for agriculture as it determines the productivity of the crops and Weather parameters influence on agricultural operations and farm production. Un expected weather conditions are the one of the reason for crop losses in India. These losses can be minimized by making modification in field operation by using weather based agro advisories service. District Agro meteorological Unit under the project of Gramin Krishi Mausam Sewa provides weather based agro agro advisories for block level in the respective district.

The aim of this study was to estimate solar radiation and reference crop evapotranspiration by using of limited weather parameters. This paper also describes the modification of the original equation with maximum and minimum temperatures for solar radiation. Thus, modifications involved for the corrections associated with climatological parameters and also to determine the accuracy and applicability of a number of existing and newly developed formulae for calculating solar radiation from other weather variables.

The influence of the various abiotic parameters (temperature, relative humidity, sun shine hours, and rainfall) on brood area, pollen area, nectar area, strength and honey production of Indian honey bee, Apis cerana indica were worked out in terms of extent of correlation starting from the month of September, 2015 to March, 2016 at different migratory site of northern part of India. For the purpose, 21 days in performance parameter i.e., brood area, pollen area, bee strength were recorded and correlated with prevailing weather parameters recorded at meterological unit for the period of a year.
