Response of Potato (Solanum tuberosum L.) to Split Application of Nitrogen under North Gujarat Agro-Climatic Condition

A field experiment was conducted during rabi 2018-19 and 2019-20 to study the effect of split application of nitrogen under mini sprinkler system on potato yield and economics in North Gujarat Agro-climatic condition on loamy sand soil at Potato Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa. The Recommended dose of fertilizer (RDF) of potato for North Gujarat is 275:138:275 NPK kg/ha. The results revealed that the significantly higher total tuber yield (67.81 t/ha) and net return (`206104/ha) was recorded in 50 % N (103 kg) as basal and remaining 50 % N (103 kg) in two equal splits at 30 and 45 DAP along with 110 P2O5 and 275 kg K2O/ha as basal application with saving of 25 % N under North Gujrat Agro-climatic condition of Gujarat.
