Abstract

Planning how to use the land resources that are available for irrigation is crucial for reducing the problem of food security. Analytical hierarchy process methodologies were used to undertake an analysis of the appropriateness of land using the GIS approach. Each parameter's weight was assessed using a 6 x 6 pairwise comparison matrix because six parameters, including slope, distance to the nearest road, land use land cover, population density, soil texture and rainfall deficit, are taken into account. After all, the weighted overlay approach of the GIS application was used to create the ultimate land suitability map for irrigation. Using the natural break classification approach, the final map was divided into land suitability classes. Of the entire region, 12.9% fell into the highly suitable (S1) class, 85.14% fell into the moderately suitable (S2) class, and 2.57% fell into the least suitable (S3) class. The finding of the study will play a significant role in performing irrigation taking into account the input parameters and ultimately defining suitable land classes and lands that may be used in accordance with current irrigation technology.

Abstract

The results of this study revealed that the pan evaporation and sensor based irrigation scheduling along with fertigation scheduling significantly affected the plant height, fruit weight, fruit length, crop water requirement, crop yield and water use efficiency of okra crop. The pan evaporation and crop evapotranspiration (ETc) values significantly vary over different stages of okra crop. The maximum and minimum average daily pan evaporation was recorded 8.4 mm day-1 and 4.5 mm day-1 at mid stage and late stage of okra crop respectively while, the maximum average daily ETc was recorded 7 mm day-¹ at mid stage of okra crop. A approach of irrigation scheduling with 100 per cent field capacity, based on soil moisture sensor under automated drip irrigation system along with 100 per cent RDF through fertigation in equal splits at 4 day intervalor 80 % per cent of volume of crop water requirement based on pan evaporation under automated drip irrigation along with 100 per cent RDF through fertigation in equal splits at 2 day interval, can be used for irrigating okra crop with significant water saving, crop yield and water use efficiency under limited availability of daily weather datain climatic condition of Udaipur district of Rajasthan.
