Evaluation of drip irrigation and fertigation in african Marigold (Tagetes erecta L.)

The present investigations were carried out to study the effect of drip irrigation and fertigation in African marigold (Tagetes erecta L.) variety Punjab Gainda No. 1. Growth parameters in terms of plant height, plant spread and number of branches were recorded maximum with treatment combination of (Flood irrigation with fertiliser application of nitrogen @ 100% RDF) for both the years 2017 and I⁰N³ 2018. Yield attributes such as number of flowers per plant and flower weight per plant were recorded highest with treatment combination of I₃N₃ (1.0 ET_C with drip irrigation + fertigation with nitrogen @ 100% RDF) for years 2017 and 2018. Highest water use efficiency values (10.04 q/ha-cm and 14.70 q/ha-cm) were recorded with 0.6% ET_C + 100% RDF for 2017 and 2018, respectively.
