During the investigation sucking pest viz; white fly and jassid were appeared in 33 standard meteorological week and maximum population of whitefly (0.60 per plant) and jassid (0.40 per plant) was recorded in 37th SMW. Correlation with sucking pest (whitefly and jassid) population and meteorological parameters was found positive non significant association with evening relative humidity and minimum temperature but negative correlation with maximum temperature, morning relative humidity and rainfall.

The historical rainfall data for the period of 37 years (1981-2017) of Junagadh district in Gujarat were analyzed for selection of most appropriate probability distribution of rainfall. From the analysis, it was found that one single probability distribution has not been found appropriate to represent all the data sets though Gamma distributions, Gumbel max.distribution and generalized extreme value distribution were found promising for most of the data sets.

Field experiment was conducted during 2011-2015 at Sisal Research Station (22.041°N, 84.295°E, 267 m above mean sea level, AMSL), Bamra, Odisha, India to study the effect of drip-irrigation and micronutrients (Zn and B) on growth, fibre yield, water use efficiency, nutrient and micronutrient content in sisal (Agave sisalana Perr. Ex Engelm.). It was observed that interaction of drip-irrigation @ 4 l/hr for 2 hrs at 2 weeks interval during 14-23 standard meteorological week (SMW) x micronutrients (zinc sulphate @ 20 kg + borax 15 kg/ha) produced the longest leaf (97.2.

Drought analysis offers a better scope for predicting the occurrence of drought to help in crop planning in rainfed regions. In view of this, an attempt has been made to evaluate drought reoccurrence patterns of weekly, seasonal, monthly and annual rainfall according to the severity, based on 17 years (2000-2016) data of Mungeli, Chhattisgarh. The observed data shows that 38th and 39th standard meteorological week experienced maximum (58.82 %) disaster drought and followed by SMW 24th and 26th. It was also observed that no drought condition was experienced maximum 52.94 in SMW 32nd.
