Abstract

ABSTRACTOne of efforts to increase rice production at swamp area which is frequently flooded is the use of submergence tolerant rice varieties. The objectives of this research was to improve plant tolerance after submergence stress for 14 days in BC1F1 of crosses between local superior varieties and Sub1 gen donor (FR13A). The studies were carried out in two stages: 1) Crossing local superior varieties, i.e., Pegagan (Pgn), Siam (Sm), Payak Selimbuk (Pys), dan Pelita Rampak (Plr) to submergence tolerant variety FR13A; and 2) submergence tolerance evaluation of the progeny. The first study was conducted at green house of Graduate Study Sriwijaya University, Palembang. The second study was carried out at field experiment of Central Research and Development of Agricultural Biotechnology and Genetic Resources in Bogor. All studies were conducted from March 2011 until March 2013. The first study was the introgression of Sub1 gene into local genotypes Payak Selimbuk, Pegagan, Siam and Pelita Rampak from FR13A. The second study was evaluation of BC1F1 plant performance after submergence treatment for 14 days. The results showed that introgression of Sub1 gene into local varieties improved submergence tolerance as indicated by higher percentage of survived plants, lower decrease of plant dry weight, and lower decrease of grain weight per panicle compared to parents.Keywords: Sub1 gene, local swamp rice, submergence tolerant

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).

Abstract

Plants get stressed shortly after submerged, to improve the recovery and subsequent metabolic processes as well as internal repairs required plant availability of adequate carbohydrate reserves after submerged. Giving fertilization treatment after being submerged is an effort to improve plant recovery after being submerged. This study was aimed to obtain the best fertilization to increase rice recovery to submergence stress through the fertilization after being submerged. The experimental design used was factorial completely randomized design with three replications. The factor consists of rice varieties (Inpara 3 dan IR 64) and treatment (N): Without soaking, basic fertilization (N1), submerged 7-14 DAP (fertilization of N, P2O5, K2O (N2), and fertilization of N, P2O5, K2O + (Si + Zn) (N3), as well as fertilization of N, P2O5, K2O + PPC micro (N4)) given 7 days after submerged, the submerged 7-14 and 28-35 DAP (N, P2O5, K2O (N5), and fertilization of N, P2O5, K2O + (Si + Zn) (N6) and fertilization of N, P2O5, K2O + PPC micro (N7)) given 7 days after the first submerged. The results showed that the growth and grain yield decreased with more frequent of rice plants in stress submerged condition. Fertilization can improve recovery after being submerged rice plants, where the best recovery obtained on varieties of rice plants treated with fertilization of N, P2O5 and K2O + PPC micro 7 days after being submerged.

Abstract

Flood is general phenomenon found in most areas of Indonesia. This can obstruct rice crop cultivation on lowland swamp areas. Fertilization strategy is one of the efforts to increase rice crop growth and production on flooded condition. The objective of this research was to determine the best fertilization strategy on vegetative stage related to rice crop growth and production under flooded condition at two types of lowland swamp. The experimental design used in this research was split-plot design with three replications. The main plot was fertilization treatment consisting of P1 = base fertilization, P2 = fertilization before flooded, P3 = fertilization after flooded and P4 = fertilization before and after flooded. The subplot was rice variety which consisted of V1 = Inpara 3, V2 = Inpara 5, V3 = IR 64 and V4 = Ciherang.  The results showed that fertilization strategy was capable of increasing rice crop growth and production under flooded condition at two types of lowland swamp.  Rice variety Inpara 5 added with fertilizer before flooded on shallow-backswamp and fertilizer addition before and after flooded on middle-backswamp was the best treatment that had produced rice yield with magnitude of 4.48 and 3.43 ton per hectare, respectively.

Abstract

Non-tidal swamp is one of suboptimal land available to increase rice production in Indonesia. The problems is stagnant flooding during vegetative growth phase of the crop. Therefore, it is important to have rice varieties that tolerant flooding. Crossing and selection have been conducted to obtaine BC2F2 genotype from local swamp rice varieties, i.e. Siam, Pegagan and Pelita Rampak. This research was aimed at knowing the growth and production of several genotypes BC2F2 and their parental varieties, Siam, Pegagan and Pelita Rampak. The research was conducted in non-tidal swamp in Village Sako, sub-district Rambutan, District Banyuasin, South Sumatra from October 2017 to March 2018. Rice genotypes have been used BC2F2 Siam, BC2F2 Pegagan, and BC2F2 Pelita Rampak, and their parental varieties i.e. Siam, Pegagan, and Pelita Rampak. The results showed that genotype BC2F2 had vegetative and generative characters different from those of Siam, Pegagan, and Pelita Rampak. The production of the tested rice varieties was high, ranged from 4.52 to 7.95 tonnes per hectare. The best of each genotypes planted in the first season were SM 2, PGG 4, and PLR 3. While the best BC2F2 of each genotypes planted in the second season were SM 2, PGG 3, and PLR 3.
