چکیده

In our present study, GARCH family models are used for modeling and forecasting the rice yield of four provinces of Pakistan during the period of 1947-48 to 2008-09. Also Auto regressive, moving average and Autoregressive moving average models are described. Thus, the selected GARCH models for all provinces are also presented for forecasting purpose on the basis of two criteria AIC (Akaike information criteria) and SIC (Schwarz information criteria). This assessment recommended that the province of Punjab in Pakistan better forecast as compared to other three provinces.

Optimization of rice (Oryza sativa L.) and subsequent soybean (Glycine max L. Merr) cropping calendars under the climate change conditions using dynamical general circulation models (GCMs) and DSSAT crop model

Climate change and the global warming phenomenon is one of the main concerns of human societies. In this study, the impact of climate change on rice, as the main crop in Guilan province, Iran and soybean production as the second crop was investigated. To adapt to the negative impact of climate change in future, optimal crop calendars were indentified for different rice and soybean cultivars usi...

Soaking seeds with paclobutrazol enhances winter survival and yield of rapeseed in a rice-rapeseed relay cropping system

Rice-rapeseed relay cropping is an effective way to use winter fallow fields and increaseland use efficiency. However, the overlapping period of 10–15 days for rice-rapeseedcultivation results in reduced winter survival and less yields. Therefore, in this study, weinvestigated if the treatment of oil rape seeds with paclobutrazol (PAC) improves its winterhardiness and yields by altering its cro...

Irrigation water deficit is an important factor that affect rice production in the world as well as Guilan province in Iran. Intermittent irrigation method can be applied to compensate for the water shortage in rice growing areas, however, it would affect other crop mangement practices such as fertilizer application and mangement. Therefore, this experiment was conducted to determine optimum fe...
