Abstract
This study was aimed to determine the yield of some maize varieties grown under different planting systems on dry land of Northern Lombok, Indonesia. Th e experiment was designed using a completely randomized block design, with two factors, namely maize variety and number of maize population which is realized from row spacing. The maize variety factor consist of 4 composite varieties (P4IS, Gumarang, Lamuru and Sukmaraga), and one hybrid variety (NK212). The row spacing factor consist of 5 types, namely 4 types of single row spacing (20x70 cm or 71428 plant/ha, 20x60 cm or 83333 plant/ha, 15x70 cm or 95238, and 15x60 cm or 111111 plant/ha), and double rows spacing (“jarwo”), that is 2:1 (20x35)x70 cm or 107142 plant/ha. The yield of maize was determined through dry seed weight per plot. Data collected were analyzed using analysis of variance at 5% level. The difference among treatments, then further tested using Honestly Significant Difference (HSD) at the same level. The results showed that there were interactions between varieties and row spacing for the yield of maize on dry land during the rainy season. The yield of all varieties tested under double spacing (“jarwo”) and the single spacing of 15x60 cm are similar, both are higher than the yield of wider single row spacing. Yield of NK212 hybrid (5.397 t/ha) is hig her than the four other composite maize varieties. The “jarwo“, with one plant per hole, gives a yield of 5,064 t/ha which is the same as the 15x60 cm single row soacing (5,026 t/ha), both are higher than the yield of the other three wider single row spacing.
