Abstract:
The present investigation “Studies on effects of graded levels of zinc and Trichoderma viride, Pseudomonas striata on yield and quality attributing characters in tomato (Lycopersicon esculentum L.)”. The experiment was laid out in Factorial RBD with two factor i.e. factor first is zinc solubilizers and factor second is levels of zinc, it has twelve treatments replicated three times. Trichoderma viride and Pseudomonas striata are used as source zinc solubilizers along with different levels of zinc. The experiment framed was intended to study the effect of zinc solubilizers and levels of zinc on yield and quality of tomato. The results revealed that effect of zinc solubilizers on yield and quality parameters of tomato indicated that the zinc solubilizer B₂ (Trichoderma viride) recorded maximum fruit yield per plant (1458.76 gm), fruit yield per plot (20.42 kg), fruit yield per hectare (567.15 qt.), maximum titrable acidity (0.38%), TSS (5.22%), ascorbic acid (22.81 mg/100gm), reducing sugars (1.61%), non reducing sugars (2.70%), total sugars (4.31%). The effect of different levels of zinc on yield and quality parameters of tomato indicated that the levels of zinc Zn₃ (30 kg ZnSO₄/ha) recorded maximum fruit yield per plant (1305.09 gm), fruit yield per plot (18.26 kg), fruit yield per hectare (507.43 qt.), maximum titrable acidity (0.36%), TSS (4.77%), ascorbic acid (22.04 mg/100gm), reducing sugars (1.48%), non reducing sugars (2.61%), total sugars (4.09%). The interaction effect of different zinc solubilizers and levels of zinc on yield and quality parameters of tomato indicated that the B₂Zn₃ (Trichoderma viride + 30 kg ZnSO₄/ha) recorded maximum fruit yield per plant (1698.33 gm), fruit yield per plot (23.77 kg), fruit yield per hectare (660.27 qt.), maximum titrable acidity (0.43%), TSS (5.39%), ascorbic acid (23.35 mg/100gm), reducing sugars (1.71%), non reducing sugars (2.80%), total sugars (4.51%).
