Abstract:

A field experiment was conducted at Department of Cotton, Tamil Nadu Agricultural University, Coimbatore during winter irrigated season 2019-2020 to study the effect of drip fertigation on growth and yield parameters and fertilizer use efficiency (FUE) of cotton under high density planting system (HDPS). The field study consisted of eight treatments, in which drip fertigation was given in T1 to T3 with 75%, 100% and 125%of recommended dose (RDF, 80:40:40 kg NPK/ ha) as straight fertilizers N and K (urea and MOP) and SSP was applied as basal dose. In T4 to T6 fertigation provided with 75%, 100% and 125% RDF of water soluble fertilizer (19:19:19). Drip irrigation with 100% RDF (all as soil application) was given in T7 and T8 with drip irrigation and STCR based fertilizer application. The experiment was replicated thrice in Randomized Block Design. The treatment T6 where drip fertigation supplied with 125% RDF of WSF recorded the highest growth parameters (plant height, leaf area index and dry matter production) and yield parameters (number of sympodial branches/plant, number of bolls/plant, boll weight and seed cotton yield) compared to all other treatments. 75% RDF through WSF recorded highest nitrogen FUE and drip irrigation with STCR based fertilizer application reported highest values of phosphorus and potassium FUE.
