Fall armyworm Spodoptera frugiperda is an invasive alien pest that attacks mainly maize crop. Influence of weather parameter on the incidence of S. frugiperda larva on maize was studied during 2019-2020 at Cauvery Delta Zone, Tamilnadu, India. Random survey was conducted in six maize growing areas and correlation between larval population and weather parameters like maximum temperature, minimum temperature and rainfall was worked out. The larva population had significant positive correlation of both same (r = 0.32 to 0.45) and previous week (r = 0.21 to 0.52) at all the locations.

This study aims at to analysis the socio economic comparison in seedling production per acre, merits and demerits of machine transplanting in Cauvery delta zone. The focused research study revealed that majority of the farmers with the farming experience of 10 -30 years, cultivating major varieties viz., ASD 16, ADT 43 and Ponni reported the total cost of production in mat nursery method is much less than the conventional method and it saves 59 percentage in cost of production when compared to conventional method.

The weather variables affect the crop differently during various stages of development (Tripathi et al., 2012). Thus, extent of weather influence on crop yield depends not only on the magnitude but also on the distribution pattern of weather variables over the crop season.

Studies were undertaken to elicit information on performance of Bambusa balcooa and Bambusa vulgaris across five agro climatic regions as well as different age gradations, association among the biometric attributes. Bambusa balcooa proved its significant phenotypic superiority in terms of all the biometric attributes studied. The performance of Bambusa balcooa across the agro climatic regions viz., North Eastern Zone, Northern Zone, Western Zone, Cauvery Delta Zone and Southern Zone was also consistent and higher than the Bambusa vulgaris and Bambusa bambos.

A study was carried out to assess the impact of shelter designs on the production performance of dairy cattle in the three selected agro – climatic zones of Tamil Nadu. viz., Southern, Cauvery delta and High rainfall zones. The effect of various shelter designs on the activity of liver enzymes and stress hormones were analyzed. The serum samples were collected throughout the year i.e. in all the four seasons, viz., winter, summer, south-west monsoon and north-east monsoon.

Meteorological drought is a natural hazard that can occur under all climatic regimes. Monitoring the drought is a vital and important part of predicting and analyzing drought impacts. In the present study, monthly time series of rainfall data (1980–2016) from five stations were used to derive SPI, particularly at 3-month time scales. This 3-month SPI was interpolated to depict temporal patterns of meteorological drought and its severity during 2014 and 2016 years. SPI was more efficient than departure in spatial analysis of drought.

This paper explore spatial and temporal dimensions of farm diversification of Cauvery Delta Zone (CDZ) for 20 years. In addition, it focuses on percentage of deviations from average area under cultivation of major crops in CDZ. Paddy is the major crop cultivated in CDZ. It accounted for nearly 65 percent of the gross cropped area. Recently farmers in the CDZ are shifting from paddy to diversified crops. Hence to examine this issue the study was taken up.

Agriculture is the backbone of Indian nation. Climate and technology are the parents for agriculture. Agriculture in Tamil Nadu is unique in its character, with respect to climate. It has varied agro-climatic zones which favors for the growth of various types of crops in the country. On the other hand it also depends on technology. Hence the present study was planned to analyses the performances of selected crops with respect to the technology. For this study, Paddy crop from Cereals is purposively selected.

A study was carried out to assess the impact of shelter designs on the production performance of dairy cattle in the three selected agro – climatic zones of Tamil Nadu, viz. Southern, Cauvery delta and High rainfall zones. The effects of various shelter designs on the haematological parameters were analyzed. The whole blood samples were collected throughout the year i.e. in all the four seasons, viz., winter, summer, south-west monsoon and north-east monsoon.
