Abstract

Reduced productive rice fields to non-paddy fields, most possible extension of the nationalrice cultivation area to the suboptimal lands reaching ± 91.9 million ha. Technologypackages that can be applied include the use of new improved rice varieties through theassembling of varieties that have high yield potential, resistant to suboptimal soil stress. Theobjective of the research is to produce new superior rice varieties that are available invarious environments. The study used a split-plot design, as the main plot is an environmentconsisting of rice paddies and gogo, as a subplot is the genotype of rice. The treatment ineach environment is prepared using the Randomized Complete Block Design (RCBD). Thetreatment consisted of 10 new rice strains and four varieties as a comparison. Variablesobserved (1) plant height; (2) the maximum number of shoots; (3) number of productiveshoots; (4) long panicle; (5) the number of grains per panicle; (6) the amount of graincontent of each panicle; (7) the number of empty grains per panicle; (8) weight of 1000grains of grain; (9) grain yield of each clump; (10) grain yield per hectare. Data wereanalyzed by variance if there was a difference between mean, median treatment, followed byLsd test at 5% level. The adaptability and yield stability of each strain was determined basedon the value of the coefficient of diversity (KK) (Francis and Kenneberg, 1978) in Syukur etal., (2012). The results showed that seven new rice strains had adaptations both planted asupland rice and lowland rice, namely strains B3, B4, F2, F3, H1, H4, and L2.

Abstract

Kiambang (Salvinia natans) which a water plant became a seriously problem in the use of Reservoir Batutegi, because nearly 80% of its surface covered by Salvinia natans. The presence of highly abundant of Salvinia natans have highly potential to be used as a source of organic fertilizer. The purpose of this study was to examine the effect of the application of biological technology (decomposers) and cow manure on the quality of the resulting compost kiambang. This study used randomized block design and experiment arranged in factorial 4 x 4 with three replications. The first factor was the dose of decomposers which consists of 4 levels, namely A1 = 0 ml, A2 = 20 ml, 30 ml dose = A3, and A4 = 40 ml decomposers per quintal kiambang respectively. The second factor was the dose of cattle dung, i.e. B1 = 0 kg, B2 = 10 kg, 20kg = B3, and B4 = 30 kg manure per quintal kiambang. The results showed the compost that has the best quality in terms of physical and chemical compost was the compost derived from the treatment of 30 ml and 40 ml decomposers per quintal kiambang which combined with 10 kg, 20 kg or 30 kg manure per quintal kiambang.

Abstract

One of the disadvantages of oil palm development is the limitedness of fertile soil. A constraint faced by both big plantation and small holders is the high cost of crop maintenance. Around 60% of the total crop maintenance is used for fertilizing the crop. This study aims at finding out phosphate absorbtion and the growth of oil palm seedling with the addition of Arbuscullar Mycorrhizal Fungi (AMF) and different dosages of phosphate fertilizer. A factorial Complete Randomized Design with three replications has been used. The first factor was the addition of AMF consisting of three levels: M0=0 g AMF polybag-1, M1=5 g AMF polybag -1, and M2 = 10 g AMF polybag -1. The second factor was the addition of four levels of phosphate using TCP-36: P0= 0 g TCP-36 polybag-1, P =15 g TCP-36 polybag-1, P2=30 g TCP-36 polybag-1, and P3=45 g TCP-36 polybag-1. Results showed that the Application of 10 g AMF polybag-1was able to increase P-absorbtion and the growth of oil palm seeding such as fresh crown weight, dry crown weight, fresh root weight, dry and root weight. Application of 45 g TCP-36 polybag -1was able to increase the growth such as plant height, dry crown weight, fresh root weight, and dry root weight. Keywords: Arbuscullar Mycorrhizal Fungi, phosphate, and oil palm

Abstract

Gladiolus propagation effort has been experiencing problems because of active buds on gladiolus corms in normal conditions is generally. Shoots will grow and then will produce tubers. So for rapid multiplication of gladiolus necessary effort to stimulate active shoots found on gladiolus corms. The use of benzyl adenine was effective enough to stimulate the emergence of shoots on gladiolus corms. Earring size seedlings generally will affect the size of the new corms. In general, if the new corms are formed more than one will affect the size of the next Earring. Fertilization-rise is expected to enlarge the size of the corm so that it can directly be used as a corm production. This study aims to find methods of rapid propagation of gladiolus corms by: (1) the effect of initial corm size on the number and size of the new corm, (2) the effect of fertilization dose on the growth of earrings, and (3) the effect of fertilization at each dose respective initial corm size. This study is a continuation of previous studies that aimed to obtain an effective concentration of BA to stimulate the growth of shoots contained in gladiolus corms. This research used the BA 30 ppm (the results of previous studies) is applied to the gladiolus cultivars Kaifa. The treatment applied to the three sizes of 3.8 to 4.8 cm diameter Earring (U1), 2.5 to 3.7 cm (U2), 1.2 to 3.0 cm (U3). The results showed that administration with a concentration of 30 ppm BA, able to grow all of gladiolus corms which were attempted (100% sprout more than one bud), and capable of increasing the number of active buds and number of shoots by 4.6 by 6.4.

Abstract

Land ownership is an important factor for the Indonesian population who lives still depend on agriculture. Ownership of land is not only important for agriculture but also to assess the needs of others in their social life. So, land not only serves as an asset but can also function as a commodity that can be traded, it also serves as a social status for their owners. Land transactions, especially in rural areas, expansive effect on tenure and rural incomes, which may have implications for the emergence of a variety of land tenure in the countryside. The results PATANAS (Panel Petani Nasional) 2010 conducted by the Center for Social and Enonomi of Agriculture, over the period 2007 to 2010 shows that the country has decreased, especially in Java land, while the villages outside Java are experiencing the opposite of a sharp increase in ownership. This indicates that the Panel Petani Nasional for 3 (three) years, indicating that that in that period there has been a fluctuation in land ownership. Whilst the change is not so prominent, but the tunakisma (lendless) in rural areas are likely to continue to grow. This certainly has implications to changing socio-economic conditions for rural communities concerned, same with the changing status of tenure communities. This paper is part of research that focuses on PATANAS 2010 villages based producer of rice paddy fields as national Keywords: Pattern Dynamics Control, Wetland, Rural Areas

Abstract

The purpose of this study to determine the role of gibberellins in enhancing the quality of soybean seeds that have experienced deterioration / decline. This research is using a complete randomized group design (RKTL) two factors. The first factor is pengusangan soaking seeds with 20% ethanol. P0 = Without soaking, P1 = Immersion 15 minutes. P2 = Immersion 30 minutes. The second factor is the provision of gibberellins with gibberellin soaking treatment for 2 hours. G0 = without soaking gibberellins, gibberellin soaking G1 = 20 ppm. Each treatment was repeated 3 times. Analysis of data using analysis of variance and to know the difference between treatments, conducted LSD (Least Significant Difference). Each with a real level of 5%. The results are: 1). Application gibberellins showed no recovery of seed deterioration, because pengusangan seeds with ethanol has not shown any significant effect on seed deterioration. 2). Application giberelin the percentage of seed germination and seed vigor percentage lower that 66, 62% and 44.00% compared with that without the application of gibberellins 91.22% and 66.67%, due to the application of gibberellins, sprouts many broke. Might be due to cell division and enlargement of the seed is not offset by the formation of cell walls, so that the cell wall is weak and vulnerable to fractures sprouts 3). Application gibberellins produce a longer hypocotyl length 10.69 cm compared to that without the application of gibberellins that is 7.94 cm. 4). Application gibberellins produce root length is shorter on the 7.73 cm compared to 8.10 cm without the application of gibberellins Keywords: Deterioration, Soybean, Gibberellin
