Growth and yield performance of Sponge Gourd (Luffa cylindrica) under different doses of nitrogen fertilizer

An experiment was carried out at a farmer’s field in Nowpara village, Trishal upazila, Mymensingh from 3rd May 2023 to 15th September 2023 to find out the effects of nitrogen (urea) fertilizers on the growth and yield performance of sponge gourd. The field experiment was arranged using a randomized complete block design with local variety Fujian F1 with four treatments and three replications viz. (Urea) T1: Control (0 kg N/ha), T2: 25 kg N/ha, T3: 50 kg/ha, T4: 75 kg N/ha were used for the present study with three replications. In treatment T4, the tallest sponge gourd plant was 123.5 cm, while in treatment T3, it measured 112.5 cm. For treatment T1, the smallest plant measured 61.33 cm. In terms of leaf numbers, treatment T4 had the greatest number of leaves 63 while treatment T1 had the lowest number of leaves 30. The highest diameter of the leaf measured was 13.05 cm in T4 and the lowest diameter found was 6.8 cm in T1. Out of the four treatments, treatment T4 had the tallest leaves, measuring 12.73 cm, followed by treatment T3, which had leaves measuring 9.7 cm. In T1 and T2, the smallest leaf lengths were found to be 6.7 and 7.8 cm, respectively. The tallest length of the petiole found was 7.8 cm in T4 and the smallest length of the petiole recorded was 5.5 cm for the treatment T1. The longest fruit measured from T4 was 28.33 cm, while the tiniest fruit came from T1 and measured 18.6 cm. The treatment T4 had the highest fruit weight, measuring 227 g, while treatment T3 had a weight of 176 g. The minimum weight was 93 g found in T1. Treatment T2 has shown the weight of the fruit those were 134 g.
