[GROWTH OF DRAGON FRUIT (Hylocereus constaricensis) STEM CUTTINGS AS AFFECTED BY CONCENTRATIONS AND DIPPING TIMES OF COCONUT WATER]. Dragon fruits (Hylocereus constaricensis) is commonly propagated vegetatively by using stem cutting. In this respect the use of natural plant growth regulator, such as coconut water, to promote the growth of the cuttings is very important. The objectives of this experiment were to evaluate water coconut concentration, dipping time of stem cutting in the coconut water, and the combination of both to promote the growth of dragon fruit cuttings. The experiment was arranged in Randomized Complete Block Design (2 factors, 5 replications). The first factor was the concentration of coconut water, consisting of 5 levels: 20, 40, 60, 80, and 100%. The second factor was dipping time of cutting in the coconut water, consisting of 4 levels: 2, 4, 6, and 8 minutes. The results showed that the increasing coconut water concentration had increased the shoot growth in a liner fashion. A similar trend was also observed for coconut water dipping time. The highest shoot growth was found on 60 % coconut water.

[GROWTH AND YIELD OF F4 SWAMP RICE LINES ON LINE SWAMP]. Growth and yield of swamp rice are depending on the plant ability to adapt in swampy agro-ecosystem which characterized by several limiting factors. This study was addressed to evaluate the growth and yield characteristics of six lines of swamp rice bred for the development of high-yielding rice varieties best suited for swamp land production. Evaluation was conducted in a pot experiment using UBPR2, UBPR3,UBPR6, UBPR7, UBPR9, and UBPR10 as planting materials. These lines were the F4 generation derived from crosses involving local Bengkulu swamp rice varieties. Observations were made on 13 plant characteristics, dry matter accumulation, leaf area ratio, specific leaf weight, net assimilation rate, plant height, productive tiller number, heading date, maturity date, panicle length, grain number per panicle, percent of filled grain, and plant yield (the grain weight per clump). The collected data were subjected to analysis of variance and least significant difference test at 5% level. Results indicated that all lines physiologically exhibited similar growth patterns, excepting the capability of accumulating dry matter at 40 dap. In this case, UBPR6 produced the highest dry matter accumulation (24.34 g). Based on the morphological performances, significant variations among the lines were observed on most of the observed characteristics, except on productive tiller number and panicle length UBPR10 was the line produced the tallest plant stature (160.72 cm), UBPR2 was the earliest flowering and maturing line (76,33 and 111 dap), whereas UBPR6 was the line produced the highest grain number per panicle (212,2), percent of filled grain (95%), and plant yield (82.50 g per clump).

ABSTRACT[THE EFFECT OF GOAT MANURES AND NPK 16:16:16 FERTILIZER ON THE GROWTH OF SEEDLESS GUAVA CROPS AND QUALITY OF ITS FRUIT (Psidium guajava L) AT RAINY SEASONS OF INDONESIA]. Guava var. Crystal, known as seedless guava, is one of the most popular guava in Indonesia. Compated to other guavas, seedless guava has softer texture, tastes sweeter, and has less seeds. This experiment was carried out from September 2017 to February 2018 at Harapan Makmur village, Pondok Kubang regency, and Central Bengkulu district. The objective of this experiment was to evaluate the effect of goat manures and NPK 16:16:16 fertilizers on the growth of guava crops and the quality of its fruits. The experiment was arranged in randomized complete block design (2 factors, 5 replications). The first factor tested was the dose of goat manures, consisting of 3 levels: 0, 9, and 18 kg/plant. The second factor tested was the dose of NPK 16:16:16 fertilizers, consisting of 3 levels: 0, 0,25, and 0.5 kg/plant. The results showed that goat manures significantly affected the diameter and number of branches. In addition, the dose of NPK significantly affected the diameter of branches, degree of leaf greenness, number of flower, and number of aborted flowers. Finally, the interaction between goat manures and NPK manures did not significantly affect all variables measured, except for leaf areas.

[EFFECT OF WEED COMPOST AND SYNTHETIC FERTILIZER DOSAGE ON TOMATO GROWTH AND YIELD (Lycopersicum esculentum Mill.)]. The growth and yield of tomato plants are influenced by fertilizer and nutrient content in the soil. This study aims to investigate the effect of a combination of synthetic fertilizer and weed compost on the growth and yield of tomato plants. The study was conducted in November 2016 through June 2017 in Agronomy, Faculty of Agriculture, University of Bengkulu, at an altitude of ± 10 m above sea level using a Completely Randomized Design (CRD). The treatments consisted of synthetic fertilizer at a rate of 180 kg/ha N, 150 kg/ha P2O5 and 100 kg/ha K2O (control), grass compost 30 , 40 and 50 tons/ha, 50% control + grass compost 15 tons/ha, 50% control + 20 tons/ha grass compost and 50% control + 25 tons/ha grass compost. The results revealed that the vegetative growth of tomato plants fertilized with grass compost 30 tons/ha and a combination of grass compost + 50% control did not differ from control treatment. Tomato yield fertilized with grass compost 30 tons/ha and a combination of 50% control + 15 tons/ha grass compost was higher than the control treatment. Therefore, 15 tons/ha of grass compost can reduce the dose of synthetic fertilizer by 50%.

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND. This study aims to obtain the right combination of varieties and biofertilizers to increase soybean productivity on Bengkulu coastal land. The research was conducted from March to July 2017, located in Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted with a split-plot design which was repeated three times. The main plot is two soybean varieties (Grobogan and Wilis). The subplots are two types of biological fertilizers, arbuscular mycorrhizal fungi, and phosphate solvent fungi. The results showed that the results of the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) were significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the Wilis variety showed an increase in seed weight (equivalent to 1.12 tons/ha) higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solvent fungi showed superior performance than arbuscular mycorrhizal fungi fertilizer or phosphate solvent fungi. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solvent fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). The economics of resources using arbuscular mycorrhizal fungi are not required to be combined with phosphate solvent fungi.

[PERFORMANCES OF TEN SOYBEAN VARIETIES AS INTERCROPPED WITH SUGARCANE]. An intercropping system between soybean and sugarcane may be an alternative to increase soybean production in Indonesia, but not all soybean varieties are suitable for intercropping system as different soybean varieties may perform differently under intercropping system and monoculture system. Therefore, suitable soybean varieties for intercropping should be identified to warrant the higher crop productivity. This study was conducted to to compare the growth and yield performances of ten soybean varieties in monoculture and soybean-sugarcane intercropping systems. The experiment was laid in a Split Plot Design with three replications. The cropping systems (monoculture and intercrop) were allotted in the main plots, while the soybean varieties (Gepak Kuning, Kaba, Wilis, Tanggamus, Burarang, Sinabung, Anjasmoro, Agromulyo, Ring-1, and Gema) were assigned as the sub plots and allotted randomly in each main plot. On overall, the intercropping system had significantly reduced the soybean pod number, seed number, wight of 100 seed, and, seed yield/plant, but increased plant height as compared to the monoculture system. The exceptions were observed for seed number and weight of 100 seed. The reduction of seed number was not significant on Agromulyo and Dering-1.On the other hand, Anjasmoro and Dering-1were the only varieties showed significant reduction in weight of 100 seed. Kaba, Willis, Tanggamus, Burarang, Sinabung, and Dering-1 showed their consistant performormances across the cropping systems. However, the higher seed yield/plant in both systems was observed on Gepak Kuning, Willis, Burarang, Agromulyo, Dering-1, and Gema.

On overall, the intercropping system had significantly reduced the soybean pod number, seed number, wight of 100 seed, and, seed yield/plant, but increased plant height as compared to the monoculture system. The exceptions were observed for seed number and weight of 100 seed. The reduction of seed number was not significant on Agromulyo and Dering-1.On the other hand, Anjasmoro and Dering-1were the only varieties showed significant reduction in weight of 100 seed. Kaba, Willis, Tanggamus, Burarang, Sinabung, and Dering-1 showed their consistant performormances across the cropping systems. However, the higher seed yield/plant in both systems was observed on Gepak Kuning, Willis, Burarang, Agromulyo, Dering-1, and Gema.","PeriodicalId":389025,"journal":{"name":"Jurnal Ilmu-Ilmu Pertanian Indonesia","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126383777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

[EFFECTS OF PALM OIL SLUDGE SUBTITUTION FOR SYNTHETIC N FERTILIZER ON GROWTH AND YIELD OF SWEET CORN]. Palm oil sludge (POS) contains high concentrations of organic nitrogen dan its can serve as an alternative for synthetic nitrogen fertilizer. Objective of this study was to compare the growth and yield of sweet corn as amended with different compositions of synthetic N fertilizer and palm oil sludge. Six compositions, each containing 138 kg N/ha were assigned as the treatment and arranged in a randomized complete block design with three replications. These were 100% synthetic fertilizer, 80% synthetic fertilizer + 20% POS, 60% synthetic fertilizer + 40% POS, 40% synthetic fertilizer + 60% POS, 20% synthetic fertilizer + 80% POS, and 100% POS. The results of this study indicated that the plot amended with 60% synthetic fertilizer + 40% POS produced the highest plant stature (176.4 cm), stem diameter (2.40 cm), leaf area (8712.82 cm2 ), plant fresh weight (375.19 g), plant dry weight (136.68 g), and husked ear length (17.93 cm). However, the highest observed husked ear yield was only about 61.6 % the yield potential of the sweet corn variety.

[INCIDENCE OF THE RICE YELLOW STEM BORER (Schirpophaga incertulas Walker) ON THREE RICE VARIETIES IN KEMUMU, NORTH BENGKULU]. Rice yellow stem borer (RYSB), Schirpophaga incertulas Walker, often causes yield loss in irrigated rice field. Dead heard and white ear head are the common symptomps resulted from the larval damage. The use of resistant varieties may reduce the risk of yield loss, but the resistance may lose quickly as the varieties are continually grown in a large area. The assessment of the insect incidence in rice field is necessary in order to determine the status of the pest for certain period of time. The objective of the study was to determine the incidence and damage incurred by RYSB in three rice varieties, Mekongga, Cibogo, and Situ Bagendit at farmer rice fields. A survey was conducted in December 2017-February 2018 in Kemumu, North Bengkulu Regency. Observation of RYSB was made on randomly selected 30 hills from + 1 ha area for each variety that was located adjacent to each other. Grain yield was measured from the sampled hills and from 3 plots of 9 m2 . Weight of 1000 grain was measured from grain of three sampled hills. The results revealed that the incidence of RYSB was low, as indicated by the presence of egg mass and larvae of RYSB, and no significant difference was found among the three varieties. Nevertheless, the average cumulative number and percentage of dead heart and white ear head was significantly lower in Mekongga than those of Cibogo and Situ Bagendit. In term of grain yield, however, Mekongga outperformed the other two varieties. The low incidence of RYSB might suggest that growing different variety practiced by local farmers was able to suppress pest population, and therefore it should be implemented in all main areas of rice production.
