Abstract: Pointed gourd (Trichosanthes dioica Roxb.) is an important remunerative perennial cucurbitaceous vegetable crop of Odisha and is known as the king of gourds. Fertigation practices with and without mulching has not been standardized for pointed gourd cv. Swarna Alaukik. Hence, a field experiment was conducted to study the effect of fertigation and mulching on growth, yield and yield attributing characteristics of pointed gourd cultivation in a sandy loam textured acidic soil with low organic carbon, available nitrogen and available potassium content of Odisha. It is seen that application of different graded dose of N, P and K through fertigation in association with mulching increased the pointed gourd fruit yield per hectare. The results revealed that the maximum values for the growth traits such as vine length (395.7 cm), number of leaves per plant (208.6) and leaf area (29.68 cm2) and yield and yield attributing characters such as number of female flowers (124.6), number of fruits per plant (93.90) and fruit yield (151.4 q/ha) were recorded with the application of 100 percent N, P and K (RDF) through fertigation and mulching which remained at par with treatment where 80 percent N, P and K is applied through fertigation and mulching. Thus, 80% fertigation with mulch was the most effective treatment with 20% fertiliser saving and 55.3% increase in yield compared to the control. The highest yield of these treatments were the sum total effect of different growth and yield attributing characters particularly vine length, number of leaves per plant, leaf area, number of female flowers, number of fruits per plant etc. The fruit yield increased significantly due to maximum utilization of nitrogen, phosphorus and potassium that resulted in increased vegetative growth, reflecting in turn better foliage production, increase in the vine length, yield attributing characters and finally yield.
