Abstract

Hazton cultivating methods is an engineered rice cultivation method using old seeds aged 25-30 days after seedling with 20-30 stems per planting hole. The old seeds have several advantages: their harvest period is faster, and  their plant adapts easily and minimize the embroidery. The objective of this study was to determine the effect of various fertilizer combinations and Jajar legowo planting system on the growth and yields of rice on cultivating Hazton methods. This research was carried out on July-October 2017 located in rice field of Tunjung Semi Village, Sambungmacan Sub-district, Sragen Regency, Central Java, Indonesia. Randomized Complete Block Design (RCBD) was used for this research with two treatment factors namely Fertilization (P) which consists of P1 (N 179,34 kg.ha-1, P2O5 149,94 kg.ha-1, K2O 132,3 kg.ha-1, S 29,4 kg.ha-1), P2 (N 115 kg.ha-1, P2O5 27 kg.ha-1, K2O 30 kg.ha-1), P3 (N 103,5 kg.ha-1, P2O5 9 kg.ha-1, K2O 18 kg.ha-1, Manure 2 ton.ha-1) and the Planting Method (H) consists of H1 (Hazton Jajar legowo 6:1) and H2 (Hazton Conventional). The inspected characteristics are plant height, number of tillers, content and uptake of N, P, K, spikelet fertility, grains moisture, weight of 1000 grains and rice production. The treatment P3 resulted the highest weight of 1000 grains. The treatment H1 resulted in higher rice production than the treatment H2.

Key words: Cultivation method, planting system, inorganic fertilizer, manure.
