Optimalisasi Jumlah Anakan Produktif Padi dengan Pengairan Macak-macak serta Penambahan Pupuk P dan K

Increased rice production still needs to be optimized by means of intensification such as the use of quality seeds, fertilizer and improvement of post-harvest technology. Watering is also an important component to increase the yield of rice production.Fertilization is done should consider the nutrient needs of plants, the vegetative phase to the generative phase. The purpose of this study was to determine the effect of the use of irrigation systems macak-macak with the addition of nutrients P and K on theoptimization of the increase in the number of productive tillers of rice. The method used is using irrigation macak-macak with the addition of P and K fertilizer with a dose of 50 kg / ha, 100 kg / ha, 150 kg / ha and 200 kg / ha. These results indicate thattreatment of the produced data were not significantly different for all safety parameters, with 0.634 significance in plant height 4 MST, 0,848 for the significance of the number of productive tillers and 0.403 for significance weight of 100 grains. The number of productive tillers MP4 highest one is on the treatment of 15 puppies
