Effect of different nitrogen levels on yield and yield attributes of different rice varieties in DDSR condition at Kanchanpur, Nepal

An experiment on the effect of different nitrogen levels yield and attributes rice varieties was conducted in Kanchanpur, Nepal, from March 2021 to July 2021. The laid randomized complete block design with two factors: varieties, each factor having three (Nitrogen: 60kg/ha, 120kg/ha, 180kg/ha varieties: Hardinath 1, Hardianth 3 Chaite 5) resulting nine treatment combinations. Rice seeds were sown directly experimental plots under dry condition 24, plant spacing 20x20cm^2. Growth parameters, grain yield, attributing traits recorded. statistical results revealed significant differences between treatments regarding agronomical characters, yield. indicated that 180 kg/ha level N application contributes higher height (74.502 cm), number tillers (1101.667), effective (577.222), filled per panicle (116.490), length (25.241 (4.7 ton/ha) straw (10.564 ton/ha). Among produced significantly (79.68 (25.68cm), sterility percentage, 1000 weight (24.60g) as compared 1 Chapter 5, respectively. However, characters like tillers, grains 5. Therefore, a variety Chaite5 may be used for better productivity Nepal.
