Abstract

Gribaldi G, Nurlaili N. 2019.  Morphological changes in some rice varieties through giving nitrogen fertilization in tidal land. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 353-359.  Palembang: Unsri Press. The increasing of rice production on suboptimal lands especially tidal land every year continues to be improved, one of which is through the use of alternative varieties and the provision of sufficient inputs. This study aims to determine the morphological changes of several rice varieties through the provision of N fertilizer in Tidal Land. The experimental design used in this study was a split plot design with three replications. Main plot: Application of nitrogen (N) fertilizer, namely N1= fertilizing at a dose of 90 kg N/ha; N2= fertilizing with a dose of 135 kg N/ha. Subplot: rice variety (V), V1= Inpari 30, V2 = Inpari 3, V3= Inpari 33, V4= Inpari 43, and V5= Hipa 5 Cepa. The result showed that varieties and N fertilization had an effect on the growth of several rice varieties, at the age of 42 HST in tidal land, the Hipa 5 Cepa variety tended to have better growth, at the age of 42 HST in tidal land, and treatment with doses of nitrogen fertilizer 90 kg/ha produces the best growth in some rice varieties, age 42 HST in tidal land.Keywords:  N fertilization, rice varieties, tidal land

Abstract

Rice cultivation with a ratoon system is one of the efforts to increase rice production in tidal land. This study aims to determine the effect of harvest time and nitrogen fertilization of the main plant on the growth and yield of ratoon rice in tidal swampland. This study was conducted in the Experimental Field of Banyuasin District Agriculture Office in Tanjung Lago Regency. The design used in this study was the Split Plot Design which was repeated three times. The Main Plots: Fertilization N (N) consists of N1;½ dose at planting + ½ dose of primordia phase, N2; 1/3 dose at planting + 1/3 dose at primordial phase + 1/3 dose at harvest, and N3; 1/3 dose at planting + 1/3 dose at primordia phase+ 1/6 dose at harvest +1/6 dose at 21 days after harvest.Plot: Harvest time (W) consists of W1; the main crop is harvested 5 days before 100% ripening, W2; main crop is harvested when 100% ripening, and W3; the main crop is harvested 5 days after 100% ripening. The results showed that the harvest time and N fertilizer of the main plants affected the growth and yield of ratoon rice in tidal land. Treatment of harvest time 5 days before 100% ripening and N fertilization has given 1/3 dose at planting + 1/3 dose of primordia phase +1/3 dose at harvest, tended to show higher growth and yields of ratoon rice than other treatments, that is 2.06 tons/ha or 54.2 percent compared to the main crop.
