Abstract

A field study was conducted in Selaqui, Dehradun (Uttarakhand), at the Crop Research Farm, Department of Agronomy, Maya College of Agriculture and Technology, during the 2016 kharif season. The experiment included 18 treatments, including 3 transplanting dates (15 July, 27 July, and 09 August), 2 seedling rates (1 seedling hill-1 and 2 seedling hill-1) and 3 spacings (20 × 10 cm, 20 × 15 cm and 20 × 20 cm). The experiment was replicated three times and set up using a randomized block design. The test crop was rice of the "Arize 6444 variety". Treatment T6-15 July + 20 × 20 cm + 2 seedling hill-1 obtained significantly higher growth (plant height and dry matter at harvest, yield attributes (number of effective tillers hill-1, panicle length, grains panicle-1 and test weight), grain yield (63.33 q ha-1) and straw yield (80.67 q ha-1) of rice.

Conclusion

Rice transplanted at 15 July + 20 × 20 cm + 2 seedling hill-1 obtained significantly higher growth (plant height and dry matter at harvest, yield attributes (number of effective tillers hill-1, panicle length, grains panicle-1 and test weight) and yield (grain and straw).
