Abstract

Roeselle plant (Hibiscus sabdariffa L.) are now widely cultivated, so that the need of roselle’s seed are increasing. Growing media largely determines the growth of seedlings, the use of Ultisol soil as growing media showed lower seedling growth. The efforts to overcome this can be done with the addition of manure. This study aims to determine the morphological changes of roselle seeds with the provision of manure on Ultisol soil in Polybag. This study used a completely nonfactorial randomized design with four treatments and five replications. The treatment under study consists of: P0 = without manure, P1 = cow manure, P2 = goat manure, and P3 = chicken manure. The result of this study showed the provision of manure on the planting medium affects the growth of roselle seeds in Polybag. The best seedling growth was obtained in growing media with the provision of chicken manure.

Abstract

The influence of global climate to the Indonesian climate condition has been in serious condition which was already in high intensity. Flood becomes the fenomena in almost all area in Indonesia. In a swamp area, it can obstruct rice plant cultivation. The submerged rice plant create the obstruction of the rice plant photosynthesis and stress after being submerged. So that  an effort is needed to increase  its tolerance and recovery in order the reduction of the unhulled crop can be reduced.   This study was aimed to obtain a method to increase rice stage is vegetative  tolerance and recovery to submergence stress through the arrangement of nitrogen fertilizer aplication and rice variety.  The experimental design used was factorial completely randomized design with six replications. The factor consists of rice varieties (Inpara 3, Inpara 5, IR 64) and  treatment (P): P1: no submergence, all N dosage prior planting; P2: submerged (7-14 DAP), all N dosage prior planting; P3: submerged (7-14 DAP), all N dosage prior planting + (Si+Zn); P4: submerged (7-14 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn); P5: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting; P6: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting + (Si+Zn); P7:  submerged (7-14 DAP and 28-35 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn). The results showed that the arrangement of nitrogen fertilizer application before submerged to rice plant can increase the rice plant tolerance and recovery to the submerged stress.  The increasing of tolerance and recovery can be obtained at the rice variety given ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn).
