Influence of jeevamrut and waste decomposer under different methods of application and fertility levels on growth, yield and quality of tomato

Abstract

The present investigation entitled “Influence of Jeevamrut and waste decomposer under different methods of application and fertility levels on growth yield and quality of tomato” was carried out during kharif season with total twelve treatments and three replications. Result revealed that, among various liquid organic substances, o1 (4% Jeevamrut) recorded significantly maximum plant height (73.84 and 122.60 cm) at 45 and 90 DAT, respectively, number of branches per plant (25.62), days to last picking (177.51), whereas minimum days to first flowering (40.37), days to first picking (86.90) and days taken from flowering to edible maturity (44.05). In case of yield and quality attributes, the significantly maximum average fruit weight (93.12 g), yield per plant (2.22 kg), yield per plot (18.45 kg) and yield per hectare (379.65 q), maximum fruit volume (95.31 cc), total soluble solids (4.70 0Brix), ascorbic acid (28.65 mg/100g), chlorophyll a (0.24 mg/g), chlorophyll b (0.13 mg/g) and total chlorophyll (0.35 mg/g) were reported in plants treated with o1 (4% Jeevamrut). Amongst the methods of application, significantly maximum plant height (123.11 cm) at 90 DAT, early flowering (40.20 days), maximum average fruit weight (90.80 g), yield per plant (2.23 kg), yield per plot (19.03 kg), yield per hectare (391.46 q), total soluble solids (4.72 0Brix), ascorbic acid (28.95 mg/100g), chlorophyll a (0.24 mg/g), chlorophyll b (0.13 mg/g) and total chlorophyll (0.36 mg/g) content were found with treatment m3 i.e. drenching at 30, 60 & 90 DAT + foliar spray at 15, 45 & 75 DAT. Supplementation of 100% RDF gave maximum plant height (72.23 and 121.99 cm) at 45 and 90 DAT, respectively, number of branches per plant (25.28), days to last picking (173.60), early flowering (40.60 days), early picking (89.13 days), days taken from flowering to edible maturity (45.51), maximum average fruit weight (90.14 g), yield per plant (2.18 kg), yield per plot (18.47 kg), yield per hectare (380.60 q), fruit volume (91.22 cc), total soluble solids (4.68 0Brix), ascorbic acid (28.61 mg/100g), chlorophyll a (0.23 mg/g), chlorophyll b (0.13 mg/g) and total chlorophyll (0.36 mg/g) content.
