Effect of Numbers of Seedlings per Hill on Growth and Yield of Sangyod Rice

Abstract

Rice transplanting with a high density of rice seedlings is one of factor influences on growth development and low yield quality of rice seedlings. The objective of this study was examined on rice transplanting techniques by using number of
seedling, the experimental site was conducted at paddy farmer plantation located on Tambon Don-Pradu, Phak Phayun District, Phatthalung, Thailand. CRD experimental design was tested with 3 levels of seedling density followed by
transplanting with 3, 5 and 7 seedlings per hill. Results showed growth and yield of rice transplanting with 3 seedlings per hill were significantly (p0.05) higher than transplanted with 5 and 7 seedlings per hill, mean height per hill, panicle length were 182.60 cm and 26.89 cm, respectively. A number of filled grains per panicle was 139.14 seed and yield per rai was 397 kg. This study reveales the transplanting method with 3 seedlings per hill integrated with organic management system can increase rice production and reduce use of rice grain.
