Abstract
The study entitled “Studies on the effect of drip irrigation and fertigation on African marigold
(Tagetes erecta L.)” was carried out in Rabi season of 2017 and 2018 at Research Farm,
Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana,
Punjab. The overall objective of the study is to standardize the water and nitrogen requirement
through drip irrigation for better flower yield in African marigold. The experiment was laid
out in split plot design with three replications to study the effect of irrigation (1.2 ETc, 1.0
ETc, 0.8 ETc, 0.6 ETc and flood irrigation) and fertigation with (WSF @ 60% RDF, 80% RDF,
100% RDF) on African marigold. The data on growth, floral and yield attributes were
recorded and statistically analysed. Growth parameters in terms of plant height, plant spread,
stem diameter, number of branches, size of flower were recorded higher with treatment
combination of I0N3 (Flood irrigation with fertilizer application with urea @ 100% RDF) for
both the years 2017 and 2018. Yield attributes such as number of flowers per plant, number of
flowers per unit area (m2), flower weight per plant were recorded best with treatment
combination of I3N3 (1.0 ETc + fertigation with WSF @ 100% RDF) for years 2017 and 2018.
