Abstract

Germination and growth at seedling stage are critical phases in plant life cycle, especially for physic nut (Jatropha curcas L.) usually grown in a dry land. Therefore seedling preparation plays an important role in nursery stock production. Position and depth of seed sowing affected the germination process and further seedling growth and development. A Completely Randomized Design with two factors was used in the experiment, i.e., depth of seed sowing (1, 2, 3, 4, and 5 cm) and seed position (seed with micropyle at the bottom, face-down, and layback). The result showed that position and depth of seed sowing affected the germination and early growth and development of seedling. The effect of seed position on growth and development of seedling persisted until the end of the experiment when the seedlings were two months old. Face-down position with 2 - 3 cm depth represented the best position and depth for seedling growth.   Key words:  Early seedling growth, micropyle, face-down position, layback position

Abstract

  The objective of this research was to evaluate the effect of extract of leaves, seed and root of physic nut on the germination of corn, tomato, and upland rice. Research was conducted by using Complete Randomized Block Design with two factors, i.e., plant organ (leaves, seed and root) and species (corn, tomato and upland rice). The results showed that extract of 36 g dried organ/200 ml water (0.18 g/ml water) affected seed germination of corn, tomato, and upland rice. Extract of leaves tended to reduce percentage of corn seed germination (55.30% vs 70.68%), and extract of root to reduce germination of tomato and upland rice, 52.70% and 68.67%, compared to control 76% and 84%, respectively.   Key words:  Plant organ extract, physic nut, germination

Abstract

A study to determine the best alternative substrate paper for testing seed viability in rolled paper method was conducted with 2 experiments. The first experiment studied the physical characteristic of six substrate papers, straw, filter, stencil, CD, HVS and Samson related to seed germination. The second experiment was conducted to identify the best alternative substrate for testing germination of different seeds. High and low viability of rice, maize, peanut, yardlong bean, chick pea and leafy vegetable seeds were tested with the substrate papers arranged in a Randomized  Block Design with three replications. The first experiment showed that CD and Stencil papers had good physical characters for germination substrate. Water absorption of CD and stencil papers were 28.1g and 24.4g per medium unit, lower than Straw paper (46.51 g/medium unit) but significantly higher than the international standard of filter paper  (20.7g/medium unit). In rolled paper test, no significant difference of water holding ability among the papers. Water lost during the 7 day testing were less than 2 g/medium unit for all of the papers. All of the papers including stencil and CD papers were homogenous with low coefficient of variation, less than 5%. The second experiment showed that different data of germination percentages and dry weight of normal seedlings were obtained from the diferrent subtrate papers. As compared to the common substrate straw paper, the stencil paper produced the most similar data, 100% and 91.7% similarities of germination percentage and  dry weight of normal seedlings, respectively, whereas the other papers performed 37.5 - 91.6% and 29.1 - 66.7%.   Key words:  Substrate paper, physical characteristic, seed viability testing.

Abstract

A computer program for fertigation scheduling in a hydroponics system has been developed using Artificial Neural Network (ANN) and Genetic Algorithms (GA). The ANN model was used to establish the relationship between the environmental factors and outflow volume of fertigation in a hydroponics system for cucumber. The result showed that the predicted outflow volume agreed well with those of the measured values. The correlation coefficients (R2) between the predicted and measured values were 0.9673, 0.9432, and 0.8248 for vegetative, flowering and maturation stages, respectively. Optimum schedules for vegetative, flowering, and maturation stages were in a good coincidence at R2 of 0.8808 with the amount of fertigation required by the plants as calculated using the empirical method.   Key words :  System identification, optimization, plant water consumption, fertigation, hydroponics

Abstract

The breeding of upland rice with New Plant Type characters in relatively short time can be done by using anther culture technique. The technique has been recognized as a rapid and efficient technology for crop improvement. Plant materials used in this research were F1 crossing P1 (Fatmawati x Way Rarem), P2 (Fatmawati x SGJT-28),  P3 (Fatmawati x SGJT-36), P4  (Way Rarem x Fatmawati), P5 (SGJT-28 x Fatmawati), and P6  (SGJT-36 x Fatmawati). Media for calli induction (N6) and regeneration (MS) were according to Dewi methods (2003). The results of this study indicated that P3 (Fatmawati x SGJT-36) and P6 (SGJT-36 x Fatmawati)  from resiprocal crosses gave better response in anther culture than the others crosses for their calli induction and green plant regeneration. From the six F1 crosses, 348 (53.5%) spontaneous doubled haploid (DH) pure lines were obtained, six lines from Farmawati x Way Rarem, 13 lines from Fatmawati x SGJT-28, 187 lines from Fatmawati x SGJT-36, three lines from Way Rarem x Fatmawati, five lines from SGJT-28 x Fatmawati, and 134 lines from SGJT-36 x Fatmawati.  These lines should be evaluated and characterized for their agronomical and morphological  traits.    Key words: Anther culture, doubled haploid, callus induction, green plant regeneration

Abstract

The experiment was aimed at identifying QTL (quantitative trait loci) controlling ten traits of yield, yield component and plant morphology of rice based on BC1F1 of IR75862-206-2-8-3-B-B-B//IR64 mapping population consisted of 115 plants.  It was arranged in Completely Randomized Design with three replicates.  Ninety three SSR markers spread across the twelve rice chromosomes were used to map the QTL.  These markers were mostly segregated according to Mendel Law except for fourteen markers.  There were eleven QTL detected in eight traits, i.e., heading date, flag leaf length, plant height, panicle length, panicle weight, seed set, weight of 100 grains, and grain weight per plant, meaning that one or two QTL were detected in each trait.  These QTL were located at chromosome 2, 3, 4, 6, 11, and 12.  Some QTL were located at the same chromosome even at the same location indicating the close association of the traits.  It also indicated that there were common QTL which were found across genetic background and specific QTL which were found at specific genetic background.  Further study was prospective for the molecular marker application in rice improvement.   Key words: QTL, agronomic traits, SSR, rice

Abstract

The objective of the research was to study the nutrition uptake (nitrogen, phosphorus, and potassium,) and the grain production of five rice varieties representing modern, new plant type and local varieties under application of inorganic, organic and combined inorganic-organic fertilization. Five rice varieties were Way Apoburu and IR-64 (modern varieties), Midun and Sarinah (local varieties from Sukabumi and Garut, respectively), and Fatmawati (new plant type variety).  Five fertilizer treatments were (1) full recommendation dosage of inorganic fertilizer (250 kg urea/ha, 100 kg SP-36/ha, and 100 kg KCl/ha), (2) ¼ recommendation dose of inorganic fertilizer + rice straw, (3) ½ recommended dose of inorganic fertilizer + rice straw, (4) rice straw, and (5) green manure from Crotalaria juncea biomass. The results showed that there was no specific response of rice varieties to the fertilization treatments, even though there was specific nutrient uptake pattern and yield of each variety, and there was significant effect of fertilizer treatment to nutrient uptake and rice yield. Nutrient uptake and grain yield indicated that nutrient imobilisation occurred at 1stseason, however the availability of N, P, K nutrients increased at 2nd and 3rdseason on rice straw and green manure treatments. Rice straw application caused lower nutrient uptake and grain yield than full dosage inorganic fertilizer at 1st season but both were not significantly different at 2nd and 3rdseason.  Application of rice straw with  ½ dosage of inorganic fertilizers was not significantly different from full dosage of inorganic fertilizers in nutrient uptake and grain yield. Modern varieties showed higher level of N absorption than that of new  type variety although it was not significantly different with that of local varieties, whereas the P and K uptake of modern varieties was lower than that of local and new plant type varieties. The modern varieties also showed higher level of dry grain per hill than that of local and new plant type varieties. However yield per ha of all varieties tended to be similar.   Key words: uptake, efficiency, mineral nutrition, variety, lowland rice

Abstract

The study was conducted to investigate the effect of different organic manures and their residues on the production of vegetable soybean. The experiments were conducted at IPB Research Station in Cikarawang, Darmaga, Bogor; in  September 2005 to May 2006 and August to December 2006. Single or combination of organic manures (chicken manure, green manure, composts and rice hull ash) was applied in the first experiment; while effect of the residues were investigated in the second experiment. The treatments were arranged in a Completely Randomized Design with 3 replications. Single or the combination of organic manures and the residues did not result in significant difference in all agronomic characters, but chicken manure tended to be the best organic manure when it was used as single application. From these experiments, the highest number of filled pod was 56/plant and the highest fresh weight of filled pod was 48 g/plant from the actual population of + 200.000 plants/ha. Additional result from the experiment was that rice hull ash significantly reduced the intensity of plant pest by 75% from that of control.   Key words:  vegetable soybean, organic fertilizers, residual effects

Abstract

The objective of this research was to study the influence of invigoration on yard-long bean seed germination under salinity stress. The research was conducted at Seed Science and Technology Laboratory, Department of Agronomy IPB from September to December 2007. Seed of two yard-long bean (Vigna unguiculata Hask. ssp. sesquipedalis) varieties, i.e. 777 and Landung Super, were used to investigate the effects of invigoration treatments, i.e. water soaking, sand priming, sawdust matriconditioning, osmoconditioning with CaCl2, NaCl, KCl and KNO3, under salinity 1.0% NaCl (w/v) stress condition. Sand priming and water soaking treatments significantly enhanced the germination percentage, speed of germination and dry matter of normal seedling under the salinity stress condition. Germination percentage of seed with sand priming was 33.33% higher than tgat of control, and germination percentage of seed with water soaking was 28.66% higher than that of control. The result  suggested that sand priming and water soaking were the effective methods to improve yard-long bean seed germination under salinity stress condition.   Key words: invigoration, salinity stress, sand priming, water soaking, yard-long bean   seed
