A field experiment was conducted at Water Technology Centre, College farm, Rajendranagar, Hyderabad during rabi, 2014-15 to study the “Paprika (Capsicum annuum L.) response to fertigation levels of nitrogen and potassium”. The experiment was conducted with variety Agnirekha in a randomized block design with three replications. The treatments were eleven, viz., soil application of 100 % N and K2O with drip irrigation (T1) and with furrow irrigation (T2); drip Fertigation of 75% N+75%,100 % and 125 % K2O (T3, T4, T5, respectively); drip fertigation of 100% N +75%, 100% and 125% K2O (T6, T7, T8 respectively); drip fertigation of 125% N+75%, 100% and 125% K2O (T9,T10,T11 respectively). The 100% N and K levels were 250 N and 150 K2O, kg ha-1. Basal dose of 100 kg P2O5 ha-1 through single super phosphate was applied to all the treatments by soil application. N and K fertilizers for T1 and T2 were applied to soil in three equal splits at 10, 35 and 60 DAT and N and K fertigation was in 38 splits through urea and potassium nitrate. Drip irrigation was scheduled (T1 to T11, except T2) once in 2 days based on daily data of USWB class ‘A’ pan evaporimeter and furrow irrigation (T2) was at 1.0 IW/CPE ratio with 60 mm irrigation depth in furrows in between paired rows (80 cm/40 cm). The amount of total irrigation water applied was 6381 m3 and 7483 m3 in drip irrigation and furrow irrigation treatments respectively. The data on total fresh fruit yield (six pickings) (kg ha-1), yield attributes of chilli fruit characterstics at different growth stages were recorded.
