Effect of Graded Levels of NPK with and without Biofertilizers on Growth, Yield and Quality of Tomato (Lycopersicon esculentum Mill.) Leaf Curl Resistant Varieties

摘要

The influence of graded levels of NPK with and without biofertilizers on growth, yield and quality of tomato leaf curl resistant varieties viz., Vybhav, Nandi, Sankranti and Arka Vikas (check) was studied under field conditions during summer 2003 at the Main Research Station, University of Agricultural Sciences, Hebbal, Bangalore. Results showed that Azotobacter chroococcum and Aspergillus awamori with 115:100:60 NPK kg ha~(-1) (100% RDF) recorded maximum plant height (73.2 cm), more number of primary branches (5.2), number of leaves (55.01), increased total dry matter (176.70 g plant~(-1)), maximum fruit yield (63.061 ha~(-1)) and higher TSS (4.34° Brix). The next best treatment was 75 per cent RDF with combined microbial inoculation. Among the varieties, Vybhav yielded maximum fruit yield while the check variety Arka Vikas recorded the lowest yield.
