Abstract


Paprika (Capsicum annuum var. longam) is one of the important capsicum group known for its less pungency. Application of fertilizers through drip irrigation is known to play a vital role in enhancing the productivity and quality of many horticultural crops. In this view, studies on paprika (Capsicum annuum var. longam) were carried out at the College orchard, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, during 2006-2009 to find out the effect of different sources and levels of potassium with reference to nutrient use efficiency water use efficiency. The experiment was conducted for two seasons viz., season I (June 2007- Jan 2008) and season II (July 2008- Feb 2009) to get the concurrent result. From the study, it was observed that the crop paprika responded well to the fertigation treatments. The result revealed that application of 100 % RDF as MAP, Multi-K and SOP recorded the highest nutrient use efficiency of 60.50 kg kg nutrient-1 and nutrient use efficiency of 37.71 kg ha-1mm-1.
