| dc.description.abstract | This experiment was conducted to study the effect of nitrogen fertigation frequency on chilli crop with different dose of nitrogen application under drip irrigation using good quality water. Experiment was carried out in micro plots (2m x 2m) constructed in lab area of Department of Soil and Water Engineering, COEA&T, CCSHAU, Hissar, Haryana, India. Two fertigation frequency, weekly (F1) and fortnightly (F2) with combination of three doses of nitrogen application (N1: 75% RDN, N2: 100% RDN and N3: 125% RDN) and surface irrigation (SF1 and SF2) with 100% RDN as control with three replication. The highest yield (12.24 t/ha) was obtained under weekly fertigation treatment with 125% RDN (F1N3), followed by 100% RDN (F1N2) having (11.56 t/ha) yield. Plant height (70.27 cm) in F1N3 treatment was recorded highest and lowest plant height (57.23 cm) was recorded in F2N1 among all the treatment. In weekly fertigation treatments, fruit weight, length and thickness were recorded 12.9, 11.5 and 14.4% higher, respectively, in F1N2 and 13.9, 14.6 and 16.5% higher, respectively, in F1N3, in comparison to F1N1 treatment. The highest WUE (5.56 kg/m3) was obtained under weekly fertigation with 125% RDN (F1N3) and minimum WUE (1.83 kg/m3) was observed in SF2 treatment. The highest NUE (192.78 kg of chilli/kg of Nitrogen) was obtained in F1N1 and minimum NUE (123.03 kg of chilli/kg of Nitrogen) was observed in SF2 treatment. From all the observation, it was concluded that treatment having fertigation level of 125% RDN (F1N3) at weekly interval (F1N3) gave best results among all the treatments imposed during the study. | en_US |
