Abstract: The field experiment entitled, “Effect of different level of fertilizers on growth and yield of F1 hybrids of watermelon (Citrullus lanatus Thunb.)†in Split plot design with 3 replications. There were two factors studied in an experiment viz. a) Fertilizer levels: F1 (150:50:50 NPK kg/ha), F2 (200:50:50 NPK kg/ha) and F3 (250:50:50 NPK kg/ha) as main plot treatments and b) F1 Hybrids: V1 (Madhubala), V2 (Augusta), V3 (N.S. 295), V4 (Vigro-286) and V5 (Andaman) as sub plot treatments.
In yield attributing characters and yield, Significantly highest fruit yield per vine (5.18 kg), and per hectare (34.53 t) was recorded in the F1 hybrid Andaman. Significantly, the highest total soluble solids (9.32 ºB), total sugars (6.45%), reducing sugars (4.69%), non-reducing sugar (1.69%) and the average sensory score (7.41) was recorded in the F1 hybrid Andaman.
The highest values for yield attributing characters and yield were noticed in F3 (250:50:50 NPK kg/ha). These were number of fruits per vine (1.64), fruit yield per vine (5.50 kg), fruit yield per hectare (36.72 t), fruit weight (3.31 kg), However, the lowest fertilizer dose F1 recorded the highest total soluble solids (8.97 ºB), total sugars (6.24%), reducing sugars (4.31%), non- reducing sugar (1.83%) and the highest average sensory score (7.25).
A treatment combination V5xF3 recorded the highest number of fruits per vine (1.73), the highest fruit weight (3.46 kg), fruit yield per vine (6.00 kg), and per hectare (40.01 t). The highest total soluble solids (10.10 ºB), highest total sugars (7.22%), reducing sugars (5.01%) and non-reducing sugar (2.10%) were recorded in the treatment combination V5xF1. However, the treatment combination V5xF2 secured the highest average score (7.50) in sensory evaluation.
Taking into consideration above these two factors and their interaction the F1 hybrid Andaman showed better performance for the important characters i.e. fruit weight, fruit yield per vine, and ha when fertilized with 250:50:50 NPK kg/ha under Konkan agroclimatic condition. Thus, F1 hybrid Andaman with fertilizer dose F3 (250:50:00 NPK kg/ha) was found to be the best combination for maximization of yield of watermelon under Konkan agro-climatic condition.
