Abstract
Background: Water is one of the factors limiting rice cultivation on raindrop land. The provision of mycorrhizae can help the absorption of water in the soil solum deeper. Besides, it can also save the use of nitrogen and phosphor fertilizers in water-choked conditions. This research aimed to optimize dosage of nitrogen and phosphorus fertilizers on growth in rainfed lowland rice applied mycorrhizae. Methods: This research was carried out from April to July 2019 in rainfed lowland rice with entisol in Demangan, Sambi, Boyolali, Center Java, Indonesia The research method was a randomized complete block design (RCBD) with three replications. The first factor was the dosage of nitrogen fertilizer, which consisted of four levels, i.e., 0, 45, 90, and 135 kg ha-1. The second factor was the dosage of phosphorus fertilizer, which consisted of four levels, i.e., 0, 25, 50, and 75 kg ha-1. Result: The results showed that fertilizer dosage of nitrogen of 90 kg ha-1 and phosphorus of 50 kg ha-1 increased the leaf area index (LAI), leaf area duration (LAD), net assimilation rate (NAR), and crop growth rate (CGR). The application of nitrogen and phosphorus fertilizer can improve the Situ Bagendit variety’s physiological character better than without fertilizer. Rice cultivation in rainfed lowland rice applied mycorrhizae should use nitrogen of 90 kg ha-1 and phosphorus of 50 kg ha-1.
