Abstract

Reseacrh on tittle respons of soybean (Glycine max L. (Merill)) varieties growth and productionwith application of liquid organic fertilizer aimed to evaluate the effect of three levels liquid organicfertilizer on four of soybean verieties growth and production in dry land. The experiment designwas factorial randomized block design with two factors and three replication. The first factor wasvarieties which consisted of Anjasmoro, Wilis, Detam 1, and Detam 2. The second factor was liquidorganic fertilizer with three levels: 0; 20; 40 cc/applications which applied for seven times at 2–8week after planting (WAP). The parameters was plant height, shoor root ratio, number ofproductive branches, seed dry weight per plot, and 100 seed dry weight. The result showed thateach variety had different growth and production. Liquid organic fertilizer increased plant height4-5 WAP, shoot root ratio, and seed dry weight per plot compared without application of liquidorganic fertilizer. Interaction between varieties and liquid organic fertilizer significantly affectednumber of productive branches and 100 seed dry weight. Wilis showed the best respons withapplication of 16.75 cc liquid organic fertilizer because of its ability to produce the higher 100 seeddry weight.Keywords : soybean, production, liquid organic fertilizer, variety

Abstract

Effort to increase soybean production in dryland experiencing problems such as nutrientdeficiencies. Alternative attempt to resolve the issue that inoculation of B. japonicum is able tofixate free N2 in the atmosphere that can be utilized by soybean plants. In this symbiosis requiredisoflavone genistein is a signal molecule for nodulation. The objective of this research was knowthe respons of growth and production of soybean (Glycine max L. Merill.) on dryland withapplication of inoculation B. japonicum induced genistein and organic fertilizer. This research wasconducted at Desa Sambirejo Kecamatan Binjai Kabupaten Langkat on June - October 2012, usinga randomized block design factorial with two factors. The first factor was isoflavon (genistein)consisted of without genistein and with genistein. The second factor was combination ofB. japonicum with organic fertilizer consisted of without B. japonicum; B. japonicum;B. japonicum + fertilizer organic (10 ton/ha); B. japonicum + rice straw compost (10 ton/ha);B. japonicum + fertilizer organic (5 ton/ha) + rice straw compost (5 ton/ha). Parameters observedwere shoot dry weight, root dry weight, seed dry weight per plant, and dry weight of 100 seeds.The result showed that induction of genistein tends to increase shoot dry weight, root dry weight,seed dry weight per plant, dry weight of 100 seeds, combination B. japonicum and rice strawcompost to increase dry weight of 100 seeds, and the interaction between genistein and combinationB. japonicum and rice straw compost tends to increase root dry weight and dry weight of 100 seeds.Key words: B. japonicum, genistein, growth, production, soybean

Abstract

Rice is an important commodity in Indonesia. As time went on the narrowing of fertile irrigatedland due to conversion of non-agricultural land for the benefit of making an effort to do that is theuse of improved varieties of upland rice using proper spacing. This study aims to determine themost appropriate spacing and varieties that will enhance the growth and production of uplandrice. The research was carried out on community lahan masyarakat 1 Tanjung Sari, District MedanMedan Selayang Municipal ± 25 m altitude above sea level in the month of June to October2012. This study uses a randomized block design (RBD) with treatment consisting of five varietiesof varieties namely, varieties Situ Bagendit, Situ Patenggang, Towuti, Batutegi and Cirata, andtreatment spacing of three that is 20x20 cm, 20x25 cm and 20x30 cm and the treatment wasrepeated three times.The data obtained were analyzed using analysis of variance, followed byDuncan's Multiple Range Test (DMRT). Results of data analysis showed that the different varietiesof real observations on variables plant height, number of tillers, number of panicles, number ofempty grains, the amount of productive grain, grain weight per sample, 1000 grain weight, and theweight per sample. Spacing is not significantly different on all variables observations. Interactionsbetween plant spacing and different varieties of real variables only on observations of productionper plot.Key words: varieties, spacing, upland rice.

Abstract

The research was conducted on the farm field with ± 25 meters above sea level from May to July2012. Randomized Block Design was used with 2 factors, ie: varieties (Hercules, Mercy and Harmony)and organic fertilizers (0, 100, 200, 300 g/plant). The parameters observed were plant height, the timeof flowering, the number of branches, the time of harvest, the fruit production per plant, the fruitlength, and the fruit diameter. The results showed that the varieties significantly affected: the plantheight 2, 3, and 4 week planted, the time of flowering, the number of branches, the time of harvest, thenumber of production per plant, the fruit length and the fruit diameter. Fertilizer significantly affectedto almost all of the observation parameters except the the plant heigh 2 week planted. The interactionbetween variety and organic fertilizer affected only to the fruit diameter.Key words: cucumber, variety, organic fertilizer

Abstract

The objective of this research was to determine the right pruning times and spacing for the growth andproduction of yam (Pachyrhizus erosus (L.) Urban). This research used factorial randomized blockdesigned with 2 factors and 3 replications. The first factor was pruning time (P),namely withoutpruning (PA), pruning 7 weeks after planting (PB) and pruning 8 weeks after planting (PC) Thesecond factor was spacing (J) which consisted of 20 x 10 cm (J1), 20 x 15 cm (J2),20 x 20 cm (J3),and 20 x 25 cm (J4). The results showed that pruning significantly increased length of plant andnumber of branches. The treatment of spacing area influenced plant height. Interaction of pruningtimes and spacing increased plant height and number of branches.Key words : Yam, Pruning times, Spacing plants.
