Irrigation requirements are probabilistic in nature due to random nature of rainfall and evapotranspiration. A water balance procedure in which rainfall and evapotranspiration are considered as stochastic variables is considered. Box and Cox transformation and normal distribution were applied to estimate weekly rainfall and evapotranspiration. Total probability theorem and leaky law of probability was applied for handling zero data in rainfall and evaporation data. Siddeek and Azahar procedures were compared to estimate weekly irigation requirements for kharif groundnut crop. It is very interesting to note that Siddeek procedures give conservative estimates of irigation requirements for arid regions than Azahar approach. This is because, for a particular probability of irrigation requirement, the probability of evaporation demand is less than Azahar estimates as rainfall is very less. The cumulative irrigation requirements were fitted with Pearl Reed model and Gompertz model. Forecasting accuracy of Gompertz model was better than Pearl Reed model.

The stochastic structure of weekly evapotranspiration time series estimated from the Penman equation is analyzed using an additive model. The turning point test and Kendall's rank correlation test are applied for detecting the trend. Correlogram technique is used to detect the periodicity, which is then analyzed by Fourier series method. Significant harmonics were identified. The series is then tested for stationarity and the dependent part of the stochastic is found to be well expressed by the second order auto regressive model. As a result, the model superposes a periodic deterministic process and a stochastic component. The developed periodic-stochastic model may by used for representing the time-based structure of the evapotranspiration time series.

Many weather stations include measurements of the evaporation from a US Class-Apan evaporimeter as the basis for calculating the water loss from the crops. But most places are without such measurements, and, even where there is a pan, the measurements may be vitiated by poor maintenance. This study has shown that the relative contribution between energy and aerodynamic terms in Penman's formula on potential evaporation exists in the ratio of Δ : r which needs to be changed to Δ: 6.14 γ for the semi arid tropical location of Patancheru, Medak, Andhra Pradesh. With this modification the correlation coefficients between observed and estimated pan evaporation have changed from 0.46-0.66 to 0.94-0.99 during the test years of 1985-2002. Student's `t' test also confirmed validity of this approach.

The field study data of forage sorghum from different locations were used to validate CERES-Sorghum model. Model simulated anthesis duration ± 3 days under normal conditions and without bias (-0.8 to 2.1 days). However, model tended to overestimate anthesis duration under moisture stress conditions. Leaf area index (LAI) was overestimated as much as 50% higher than the observed values between 35 and 50 days after planting. The model performed satisfactorily in simulating total dry biomass (TDM), but it generally underestimated TDM (Bias = -1815.1 kg ha^-1) in response to different sowing date. TDM could be well predicted in response to historical weather variability in different agro climatic conditions.

Retrieval of land (soil-vegetation complex) surface temperature (LST) and ground insolation was carried out over middle Gujarat region using VIS (channel 1), NIR (channel 2) and thermal bands (channel 4 and 5) and ground emissivity from atmospherically corrected NDVI of NOAA AVHRR LAC (1.1 km x 1.1 km) images. The atmospheric correction of VIS and NIR band reflectance to derive corrected NDVI was done using SMAC model. LST computed from split-window method were then compared with near synchronous soil and air temperatures using field observations made during 13-17 of January and April, 1997 at five sites. The LST derived from NOAA AVHRR thermal channel data varied from 301.6 - 311.9K in January and from 315.8-325.6K in April. In April, LST were found to be more close to T which may be due to relatively poor vegetation growth as represented by lower NDVI values in April. The global ground insolation and its direct and diffuse components were retrieved using Heliosat and ESRA models applied to NOAA AVHRR GAC (4km x 4km) images. The satellite retrieved direct or beam insolation during May was found to be overestimated to the order of 10-15%.
