Abstract:

Field experiment was conducted at the experimental farm of Department of Soil Science, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the effect of drip irrigation and fertigation levels on yield, NPK concentration and their uptake by potato. Experiment was laid out in randomized block design (RBD) with treatments including three drip irrigation levels viz., 0.4 PE, 0.6 PE and 0.8 PE corresponding to 40, 60 and 80 per cent of cumulative pan evaporation, respectively, three fertigation levels viz., 50 % RDF, 75 % RDF and 100 % RDF equivalent to 50, 75 and 100 per cent of recommended dose of NPK, respectively and RP i.e. recommended practice (recommended dose of fertilizers through conventional methods and 6 flood irrigations of 50 mm each). The results revealed that drip irrigation levels did not have significant effect on tuber yield and NPK contents. Total NPK uptake by potato was influenced by irrigation levels but the differences between the higher irrigation levels of 0.6 PE and 0.8 PE were not significant. Fertigation level of 75 % RDF was statistically at par with 100 % RDF but significantly better than 50 % RDF with respect to yield and nutrients uptake. Fertigation level of 75 % RDF gave significantly higher marketable tuber yield (21.97 t ha-1) and it was 22 per cent higher than that obtained with 50 % RDF (18.01 t ha-1). No improvement in yield was obtained with 100 % RDF over 75 % RDF. Also, Drip irrigation and fertigation was better than the recommended practice as combination of irrigation level of 0.6 PE and 75 % RDF recorded similar yield, thereby saving 25 per cent of NPK.
