| dc.description.abstract | A field experiment was conducted during Kharif 2014 at ZARS, University of Agricultural Sciences, Bengaluru to study the effect of micro sprinkler fertigation on growth, yield, water use efficiency (WUE), nutrient use efficiency (NUE) and economics of groundnut in red sandy loam soil. The experiment was laid out in RCBD with nine treatments and replicated thrice. Micro sprinkler fertigation of WSF at 100 % RDF increased the pod yield significantly (2882 kg ha-1) over all other treatments. However, it was on par with micro sprinkler fertigation of WSF at 75 % RDF. Among the micro sprinkler fertigation treatments significant yield reduction was noticed with micro sprinkler fertigation of normal fertilizers (NF) at 50 % recommended dose. Micro sprinkler fertigation of WSF at 100 % RDF recorded significantly higher number of pods plant-1 (34.2) and WUE (64.9 kg ha-cm-1) compared to surface irrigation. Micro sprinkler fertigation of WSF at 75 % RDF recorded significantly higher agronomic nutrient use efficiency (70.3, 22.3 and 44.6 kg kg-1 of N, P and K, respectively). Micro sprinkler irrigation saved 29.8 % water over surface irrigation. Micro sprinkler fertigation of NF at 100 % RDF recorded higher B:C ratio (2.82) followed by micro sprinkler fertigation of NF at 75 % RDF (2.64). July, | en_US |
