Description The experiment entitled “Integrated nutrient management (INM) for tomato ( Lycopersicon esculentum Mill.) cv. Gujarat Tomato-2” was carried out during rabi season of 2011 -12 and 2012-13 at the Regional Hor ticultural Research Station, Navsari Agricultural University, Navsari, Gujarat. The experiment was conducted on fixed plot site with a set of twelve treatments viz., T 1(FYM 20 t ha - 1
+ 100 % RDF i.e . 75: 37.5: 62.5 NPK kg ha -1 ), T2 (FYM 20 t ha -1 ), T3 (Neem cake 5 t ha
-1 ), T4 (Vermicompost 5 t ha -1 ), T5 (75 % RDF + FYM 20 t ha -1 ), T6 (75 % RDF + Neem cake 5 t ha
-1 ), T7 (75 % RDF + Vermicompost 5 t ha -1 ), T8 (50 % RDF + FYM 20 t ha -1 ), T9 (50 % RDF + Neem cake 5 t ha -1 ), T10 (50 % RDF + Vermicompost 5 t ha -1 ), T11 (100 % RDF + ZnS04
@ 25 kg ha -1 ) and T12 (100 % RDF + FeS04 @ 50 kg ha -1 ). The experiment was conducted in a Randomized Block Design (RBD) with three replications.
Among different INM treatments FYM 20 t ha - 1 + 100 % RDF significantly gave the higher values of growth parameters and yield attributes viz., plant height (137 cm) , total fresh weight of plant (26.84 t ha
-1 ), dry matter yield of plant (7450 kg ha -1 ), number of fruits plant - 1 (33.31), fruit length (5.35 cm), fruit diameter (4.36 cm), fruit volume (66.61 cm -3 ) , total dry matter yield of fruit (2838 kg ha -1
), fruit yield plant -1 (1.54 kg), fruit yield plot -1 (30.71 kg), total fruit yield ha -1 (42.65 tonne) and marketable fruit yield ha -1 (38.1 tonne) .
With regard to the infestation of tomato fruit borer , least infestation (2.36 %) was observed in the plants fertilized with only organic manure i.e. T2 (FYM 20 t ha ). Characters like number of locules per fruit, pericarp thickness and moisture content of fruit were not significantly nfluenced by INM treatments under study .
Significant differences were ob served in the quality character of fruit due to different INM treatments. The total soluble solids (4.24 %), ascorbic acid (31.25 mg 100 g -1 ) and lycopene contents (3.10 mg 100 g -1 ) of fruit were significantly increased in the treatment receiving FYM 20 t ha - 1 + 100 % RDF. The treatment effects were found non -significant for titrable acidity, solid : acid ratio, sugar : acid ratio, fruit p H and viscosity of fruit pulp.
The remarkable increase in values of total uptake of nutrients viz., N (140 kg ha
-1 ), P (47.5 kg ha -1 ), K (71 kg ha -1 ), S (18.5 kg ha - ), Zn (613 g ha -1 ) and Fe (1454 g ha
-1 ) by tomato were observed in the treatment combination 100 % RDF + FYM 20 t ha -1 (T 1 ). Different I NM treatments had non-significant effects on N, P, K, S, Zn and Fe contents in fruit as well as tomato plant
Soil fertility status after the harvest of tomato crop was also improved. The treatment receiving FYM 20 t ha - 1 + 100 % RDF (T 1 ) significantly gave higher WSA of size >1.0 mm , w hereas, treatment T 5 (75 % RDF + FYM 20 t ha -1 ) recorded lower WSA of size 0.5-1.0 mm. followed by FYM 20 t ha - 1 + 100 % RDF (T 1 ).
The highest net return with benefit cost ratio 3.19 : 1 was achieved in the treatment T
1 (FYM 20 t ha - 1 + 100 % RDF) followed by ( T5 ) 75 % RDF + FYM 20 t ha -1 . Both these treatments were found economical, profitable and proved highly remunerative.
