| Abstract/Description: | Field experiments were conducted during 2008- 10 at Central Tobacco Research Institute, Research Station, Jeelugumilli, West Godavari district, Andhra Pradesh to study the effect of drip fertigation on yield, quality and fertilizer use-efficiency of FCV tobacco grown on light textured Alfisols in comparison to furrow irrigation. Nitrogen and potassium concentration in green leaf (70 days after planting) decreased with level of fertigation. Nitrogen and potassium concentration with 100 and 80% level of drip fertigation with recommended dose of fertilizer (RDF) and drip irrigation with conventional dollop method of fertilizer application (CFA) were higher than furrow irrigation. Different levels of fertigation (100, 80 & 60%) and drip irrigation with RDF showed higher net photosynthetic rate, stomatal conductance and transpiration rate compared to furrow irrigation. Fertigation with 100 and 80% of RDF showed significantly higher yield and net returns over other treatments. Yield increase in 100, 80 and 60% RDF was 32, 27 and 11%, respectively over furrow irrigation. Fertigation levels of 100 and 80% RDF showed significantly higher nicotine, lower sugars and chlorides than drip irrigation with CFA and 60% RDF. Based on the yield and chemical analysis it can be concluded that fertigation at 100 or 80% RDF through drip irrigation will improve the yield, fertilizer-use- fficiency compared to furrow irrigation and drip irrigation with dollop method of fertilizer application. |
