Climate change and agriculture are interrelated processes, both of which take place on a global scale. The study was undertaken to identify the trend in weather parameters in Malaprabha Command Area (MCA). The research was based on secondary data of nineteen years (1999 to 2017) on different weather parameters such as precipitation, temperature, relative humidity and potential evapotranspiration obtained from the Irrigation Water Management Research Centre, Belavatgi under UAS, Dharwad.

Present investigation was an attempt to study the trend of jute production in West Bengal for the period starting from 1950 to 2016. For stochastic trend estimation, a number of time series parametric regression models viz. Linear model, Quadratic model, Exponential model, Logarithmic model, Power model and Auto Regressive Integrated Moving Average (ARIMA) were employed and compared for finding out an appropriate econometric model to capture the trend of jute production of the country. Based on the performance of several goodness of fit criteria viz.

Rain fed lowland traditional variety rice cultivation in Andaman and Nicobar islands in acidic soils with low inherent fertility is done with minimal use of fertilizer and thus have low yields and profits. Use of hybrids and balanced fertilization especially nitrogen (N) may improve the situation. In this context, a field study was made during 2016 rainy season to assess the performance of 8 hybrids (including a variety) in main plots and four N rates (0, 50, 100 and 150 kg/ha) as sub-plot treatments. Experiment was laid out in split plot design with three replications.
