Abstract

Increasing plant capability to adapt on coastal land is very important aspect in the development alternative carbohydrate source food. The objective of this research is to determine the effect of ZA fertilizer and organic mulch on lesser yam’s adaptability based on its growth and yield. The experiment was conducted with a randomized completely block design arranged in a split plot with 3 replications. As the Main Plot were organic mulch levels, and as the Sub Plot were ZA fertilizer doses. The results showed that there was no interaction effect between ZA fertilizer and organic mulch on either growth or yield of lesser yam. Application of ZA fertilizer up to 200 kg ha improve lesser yam’s adaptability based on their vegetative growth. Organic mulch of rice paddy straw up to the rate of 20 ton ha-1 did not increase growth and yield of lesser yam in coastal sandy land.

Abstract

Bengkulu province area elevating from 0 m to over 1000 m above sea level possesses high rice germplasm diversity. To obtain salinity controlling gene(s) from those germplasm, it is required to determine a suitableprotocol. This research was objected to determine NaCl concentration to select Bengkulu rice landraces. The standard most salinity tolerant genotype used in this research was ’Kuning’, a local variety usually grown on tidal area of Seluma Regency for generations. The growing media was Yoshida nutrient culture supplemented with a series of NaCl concentration of 0, 2000, 4000, 6000, 8000 or 10000 ppm. Observation was done every 2 days to find out the response pattern of rice seedling growth on different NaCl concentration. NaCl stress level was determined at 90% seedling dead (LC90) at the eighth day. The results showed that the increase of plantheight was deceased at concentration of 6000 ppm. Based on the mathematical equation generated from the percent mortality data distribution, the LC90 was at 3910 ppm NaCl concentration.

Abstract

Bambara groundnut (Bogor groundnut) was an alternative food crops having high nourishing, better taste and bigger size nut than the soy beans and peanuts. To meet the need for food and industrial needs, the program to increase production of Bogor groundnut was required, one of which is the use of peat as a growing medium using the technology of mixing peat and mineral soil. The research objective was to obtain a mixture of peat with mineral soil and dolomite lime dose suitable for the highest growth and yield of Bogor groundnut.  This study was conducted in May 2015-September 2015 in the Greenhouses of Faculty of Agriculture, University of Bengkulu. The experiment was arranged in a completely slot deposit 5000 randomized design (CRD) with two treatment factors and three replications. The first factor was soil mix of peat and mineral soil (G0: 100% peat + 0% mineral soil; G1: 75% peat + 25% mineral soil; G2: 50% peat + 50% mineral soil; G3: 25% peat + 75% mineral soil) and the second factor was the dose of dolomite (D0: without lime dolomite; D1: 3 ton ha-1 and D2: 4 ton ha-1). The results showed that the response of biomass dry-weight to a mixture of peat with mineral soil was influenced by the dose of dolomite, but there was no interaction on other variables.  Treatment of a mixture of peat 100% alone was capable of generating the highest number of leaf, biomass fresh- and dry-weight.  Bogor groundnut plants showed the same response to the dose variation of dolomite lime.

Abstract

Blewah (C. melo var. Cantalupensis) is one specific type of melon with fresh and fragrance arome when the fruit is ripe.  Mostly the plant is grown in Java island of Indonesia.  There is no research-based  information about technique of cultivationof this plant, so this experiment was done to study population density to determine the optimal spacing for growth and yield of blewah.  The experiment has been implemented from February 2016 until May 2016 in the experimental field of the University of Bengkulu. This study used a complete Randomized Complete Block Design with different population density treatments i.e.: plant density of 4 plants per plot of 10 m2 (plant spacing 100 cm x 250 cm);  plant density of 6 plants per plot, (plant spacing 100 cm x 166 cm); plant density of 8 crops per plot (spacing of 100 cm x 120 cm); plant density of 10 plants per plot (plant spacing 100cm x 100 cm); plant density of 12 plants per plot (plant spacing 100 cm x 83 cm); plant density of 14 plants per plot (plant spacing 100 cm x 72 cm); and plant density of 16 plants per plot (plant spacing 100cm x 62 cm). Each treatment was repeated 3 times. The experiment showed that the optimal spacing for growing blewah was at population density 12 plants/10 m2 or 12,000 plant/ha, plant spacing 100 cm x 83 cm. This arrangement of plant yielded the length of  plant, the number of branches, the diameter of the fruit, the plant dry weight, the weight of the fruit per plot, and fruit thickness of 224.47 cm, 3.67, 9.61 cm, 22.15 g, 7044.80 g,  and 2.21 cm respectively.Keywords: blewah, Cucumis melo var.

Abstract

Taro (Colocasia esculenta L. Schott) is a plant that has an excellent economic and healthy value, as well as a great potential development of Bengkulu coastal area. That is because taro has wide adaptability, and can be consumed both as a staple food and healthy food alternative. This research was conducted to study the vegetative growth of two cultivars of taro given four different doses of nitrogen. This study applied a Randomized Complete Block Design (RCBD) with two factors. The first factor was the cultivar of taro consisted of two levels, namely Taro Satoimo (T1) and the Taro Local (T2). The second factor was the doses of nitrogen fertilizer which consisted of four levels namely: N0 = 0 kg / ha (control), N1 = 50 kg / ha (2.6 g, N2 = 100 kg / ha, and N3 = 150 kg / ha. Thus, obtained eight treatment combinations. Each treatment was repeated three times to get 24 plots. The results showed that based on increased vegetative growth, the cultivar Satoimo has a faster response than local cultivar. Satoimo has demonstrated another advantage because it produced some leaves and number new shoot. The best dose of nitrogen fertilizer on the vegetative growth of taro in the coastal area of Bengkulu is 150 kg/ha.

Abstract

ABSTRACTPeanut plant production has decreased almost every year, caused by several factors such as cultivation techniques, diseases, varieties, competition with other commodities and the increasingly narrow land area. One effort to improve the yield of peanuts by optimizing ultisol land for cultivation of plants. Ultisol soil is one of acid soils, high Al content, low organic matter content, and low cation exchange capacity. Provision of fertilizer is one effort made to maximize the use of ultisol land. This study aims to determine the optimal dose of cow manure and phosphorus fertilizer for peanut plants and to determine the dose of cow manure and the appropriate dose of phosphorus fertilizer for peanut plant. The design used in this experiment was Randomized Complete Block Design (RCBD) with two factors arranged factorially. The first factor was dosage of cow manure consisting of 4 treatment levels i.e. 0 ton ha-1, 10 ton ha-1, 20 ton ha-1 and 30 ton ha-1. The second factor is phosphorus fertilizer (SP-36) consisting of 3 levels i.e. 0 kg ha-1, 100 kg ha-1 and 200 kg ha-1. From these two factors, there were 12 treatment combinations each treatment was repeated 3 times, so that 36 experiments were obtained. The results showed that the dosage of cow manure did not significantly affect the growth and yield of peanut plants. The dosage of phosphorus fertilizer did not significantly affect all variables of observation except on seed weight. The combination of dosage of cow manure and phosphorus fertilizer has no significant effect on the growth and yield of peanut plant. Keywords: Peanut, Cow Manure, Phosphorus and Ultisol
