The study was carried out for stochastic modeling of reference crop evapotranspiration values estimated by Penman-Monteith method from daily records of climatic parameters. Seasonal ARIMA modeling was performed for the generation and forecasting of weekly ETr values. The steps viz. standardization and normalization of time series variables, identification of the models, determination of the parameters of selected models, diagnostic checking and selection of the best model were performed for fitting the models. The ARIMA(1,1,0)(1,0,1)52, ARIMA(1,1,1)(0,1,1)52, ARIMA(1,1,1)(0,1,1)52 and...

The study was conducted to know the appropriate probability distribution for weekly reference crop evapotranspiration (ETr) values at desired probability levels for Solapur, Ahmednagar, Pune and Nasik stations of Maharashtra, India. ETr values were estimated by Penman-Monteith, Modified Penman, Hargreaves-Samani, Pan Evaporation, Blanney-Criddle, and Radiation methods. Based on the root mean square error, Hargraves-Samani found to be the best method for Solapur and Nasik stations and Modified Penman for Ahmednagar and Pune stations. The probability distribution functions selected were...

Availability of large number of disease free genuine planting material is a major constraint in expanding area under pomegranate cultivation for which tissue culture can be explored as an alternative tool to fulfil the demand for elite planting material. In the first part of the study an efficient in vitro propagation protocol for pomegranate cv. G-137 (a superior clone of Ganesh ) has been developed. Improper hardening of in vitro raised plantlets leads to high field mortality and poor growth of plantlets which act as a hurdle in popularization of in vitro propagation in pomegranate. So, in...

The knowledge of drought monitoring, pomegranate evapotranspiration, water balance study is necessary to generate best plan for maximum production of pomegranate. In addition to this, it is important for the decision makers and planners if the values of crop evapotranspiration (ETc) are known at certain probability levels. Further, the evapotranspiration prediction guarantees a reliable project planning, design and operation irrigation systems. ETr takes care of variation in climate and kc is dependent on crop and its growth stages. In addition to this, it is important for the decision makers...
