Effect of application of types of fertilizer and number of seeds per hill on production of wheat (Triticum aestivum L.) Dewata 162 variety

Abstract

Wheat production in Indonesia is still low and has not been able to meet the needs of the community. Fertilization is an activity of providing organic and inorganic materials into the soil to replace nutrient losses from the soil, while the provision of seeds per hole can determine the right plant population. The purpose of this study was to determine the effect of the type of fertilizer and the number of seeds per hill on increasing the production of wheat (Triticum aestivum L.) Dewata 162 varieties. This research used a factorial experiment (4 x 2) arranged in a completely randomized block design and repeated three times. The first factors are the kind of fertilizer (cow manure, chicken manure, goat manure, and NPK); the second factors are the number of seeds per hill (one seed and two seeds per planting hill). The results exhibited that the provisions of fertilizer affected some parameters like the number of tillers, the number of productive tillers, plant height, panicle length, dry seed weight per clump, and 1,000 dry seed weight, but it has the same effect on dry seed weight per panicle and dry kernels weight per m2. The provisions of chicken manure gave the highest outcome to the production of wheat on the number of tillers, the number of productive tillers, panicle length, and 1,000 dry seed weight. NPK gives the highest outcome on plant height and dry seed weight per clump. The treatment of the number of seeds per hill gave the same effect on all observed parameters.
