An experiment was conducted to find the effect of different levels of nutrients through water soluble fertilizers along with Azophosmet and humic acid on biochemical attributes of watermelon. Application of 125 per cent of water soluble fertilizers viz.,250:125:125 kg/ha of NPK in addition to Azophosmet and humic acid showed the best performance in almost all the parameters studied in both seasons I and II, as it recorded the highest total chlorophyll content (1.588, 2.574, 2.426 and 2.162 mg g-1 in season I and 1.652, 2.638, 2.556 and 2.379 mg g-1 in season II, T8 recorded the highest soluble protein content (6.02, 11.66, 11.19 and 8.42 mg g-1 in season I and 6.18, 12.24, 11.58 and 9.14 mg g-1 in season II, nitrate reductase activity at all days observed during both seasons viz., season I and season II ( 9.29, 16.89, 14.0,9.11 μg NO2g-1 h-1 and 9.74, 17.24, 14.35 and 9.46 μg NO2g-1h-1 at 30th, 45th, 60th and 75th DAS. IAA oxidase was the highest at 30th DAS and declined at 45th, 60th and 75th DAS in both the seasons.Keywords
Watermelon, Water Soluble Fertilizer, Azophosmet, Humic Acid, Chlorophyll Content, Soluble Protein Content, Nitrate Reductase Activity, IAA Oxidase Activity.

An experiment was conducted to find the effect of different levels of nutrients through water soluble fertilizers along with Azophosmet and humic acid on nutrient uptake pattern of hybrid watermelon 'Kiran'. Application of 125 per cent of water soluble fertilizers viz., 250:125:125 kg/ha of NPK in addition to Azophosmet and humic acid showed the best performance in almost all the parameters studied in both seasons I and II, as it recorded the highest nitrogen uptake, phosphorus uptake and potassium uptake by plant and it showed an increasing trend from 30th to 75th DAS invariably in all the treatments during both the seasons studied. Control plots showed un-satisfactory results regarding all the parameters.Keywords
