The growth and quality of the paddy depends on the interaction between environmental and plant genetic factors. Efforts to increase rice productivity by using only superior varieties will not be effective without being followed by site-specific cultivation techniques, especially optimize plant spacing. This study was conducted to determine the optimum spacing used in planting local varieties. Materials and Methods: This study was conducted from February, 2017 until May, 2017 in Tekung Village, sub-district of Tekung, Lumajang, East Java province. The factorial experiments were using split plot design with varieties (Ciherang, Mentik and Genjah Arum varieties) as main plots and plant spacing as sub plots. The parameters included were observation of productive tillers percentage, 100-grain weight, total grain per panicle, grain weight per clump and number of panicle per culmp. Data obtained were subjected to two-way analysis of variance (ANOVA) at 5 and 1% levels, if the significance difference will be continued by fishers Least Significant Differences (LSD) test at the 0.05 probability level. Results: The results showed that the responses of each variety at various plant spacing had a significant interaction between varieties and plant spacing on the weight of grain weight per clump and number of panicle per clump. Whereas in parameter productive tillers percentage, 100-grain weight and total grain per panicle only influenced by varieties. Conclusion: The treatment of V1J40 (Ciherang variety with plant spacing 40 cm×15 cm), had the highest grain yield compared to other treatments.]]>Zaini, A.H., D. Hariyono and K.P.
