Abstract

[GROWTH AND YIELD OF MELON PLANT (Cucumis melo L.) IN DIFFERENT COMPOSITION OF PLANT MEDIA AND DIFFERENT FREQUENCY OF NPK APPLICATION]. This study aims to determine the best combination of planting media composition and frequency of NPK fertilization on the growth and yield of melon plants. The research was conducted in October 2018 - January 2019 on the land located in Bentiring, Muara Bangkahulu District, Bengkulu City. The design used in this study was a Completely Randomized Design (CRD) consisting of two factors and three replications. The first factor was the composition of the media for plant growth, which consists of three different media composition, namely: sand: soil: manure (30%: 50%: 20%), sand: soil: manure (10%: 60%: 30%), and sand: soil: manure (20%: 70%: 10%). The second factor is the frequency of NPK fertilization consisting of four types of fertilization, namely: 1 time NPK fertilization during planting, 2 times NPK fertilization during planting and 10 days after planting (dap), 3 times NPK fertilization during planting, 10 dap and 20 dap, and 4 times NPK fertilizing during planting, 10 dap, 20 dap and 30 dap. The dose given is 15 g/plant (equivalent to 800 kg/ha) and NPK fertilizer given in the form of compound fertilizer N: P: K 16:16:16. The results showed that the best composition of the planting media was found in the treatment of sand media: soil: manure (10%: 60%: 30%). The best fertilizing frequency was found in the treatment of NPK fertilizing 4 times during planting, 10 dap, 10 dap, 30 dap, and the combination of both produces the most substantial plant length, weight, and fruit circumference

Abstract

[THE IMPACT OF PALM OIL SLUDGE RESIDUES AND DOLOMITE RESIDUES ON GROWTH AND YIELD OF PEANUT (Arachis hypogaea L.) IN ULTISOL].  This study aims to determine the best interaction between palm oil sludge (POS) residues and dolomite residues, determine the best POS residue, and determine the best dolomite residue in the growth and yield of peanut plants. This research was conducted from March 2018 to June 2018, the design used was a Complete Randomized Block Design (RCBD) with two factors. The first factor is POS residue with 3 levels, 0, 10, and 20 tons/ha. The second factor is dolomite residue with 4 levels, namely 0, 2, 4, and 6 tons/ha. The results showed that the best treatment combination was obtained from oil POS residue of 10 tons/ha and dolomite residue of 2 tons/ha which produced the highest total root nodule weights of 0.2417 g. POS residue of 20 tons/ha gives the highest yield on the growth component, which is an average plant height of 16.72 cm. POS residue of 10 tons/ha gave the highest yield on the growth component, namely dry stover weight of an average of 9.57 g, as well as the yield component of 45.20 total pods, 32.84 pods, total pod weight 43.47 g, and the weight of pith pods weighing 36.60 g. The highest total dry pod weight was 2.71 tons/ha. Dolomite residue gave a higher yield on all growth variables and observed results, with the highest total dry pod weight being 2.68 tons/ha.

Abstract

[THE USE OF PAITAN BIOMASS (Tithonia diversifolia) (Hemsley) A. Gray AS A FERTILIZER IN INCREASING PEANUT YIELD]. Peanuts are one of the food crops having high economic value due to their nutritional content, especially high protein and fat. Peanut crop production has decreased due to infertile land with poor in nutrients. Efforts to increase peanut production is by including organic paitan (T. diversifolia) provision. This study aims to obtain the optimum dose of T. diversifolia compost on the yield of peanuts. This research was carried out in Pekik Nyaring Village, Bengkulu, with a height of ± 25 m above sea level, from February to April 2018. The design used was a complete randomized block design with a single factor consisting of 6 levels of treatment with four replications. Factor dosage of paitan compost fertilizer (T. diversifolia) is 0 tons/hectares, 5 tons/hectares, 10 tons/hectares, 15 tons/hectares, 20 tons/hectares, and 25 tons/hectares. Data were analyzed using analysis of variance at a 5% level. The results showed that the optimum dose of 15.5 tons/hectares produced 6.54 branches. The dosage of T. diversifolia compost 25 tons/hectares produced the highest number of pithed pods (36.08 pieces), the heaviest pith weighted pods (111.58 g), and the heaviest seed weight (87.06 g).

Abstract

[GROWTH APPEARANCE AND YIELD OF FIVE TOMATO HYBRIDS ON ULTISOL AND PEATLANDS].  Ultisol and peat are included in marginal land that can support the growth and development of plants. This study was aimed to compare the growth and yield of five tomato hybrids on ultisol and peatlands. The experiments were carried out in the field with the soil type of on ultisol and peats.  The experiment was arranged in a Randomized Completely Block Design with 3 replications. The hybrids evaluated were UNB-1 × UNB-2, UNB-3 × UNB-1, UNB-2 × UNB-1, and UNB-2 × UNB-3, and Sinta as a control hybrid.  The results showed that in ultisol lands, the diversities among genotypes were observed in some variables, including the age of flowering, a number of fruits per plant, fruit diameter, fruit weight per plant, and fruit sweetness level.  On the peatlands, a significant diversity was observed in plant height, age of flowering, age of harvest, fruit weight per plant, number of flowers per bunch. Based on this evaluation in the Ultisol soil, the yield of UNB2 × UNB1 was higher than control (Sinta genotype), whereas, in peat, the growth and yield components of UNB2 × UNB3 is the best and Sinta hybrid as a control genotypes showed the highest yield among other genotypes.

Abstract

[THE EFFECT OF PLANTING DISTANCE AND WEDDING FREQUENCY ON GROWTH, YIELD OF PEANUT (Arachis hypogaea L) AND WEED POPULATION]. This study was aimed to determine planting distance and frequency of weeding which gives the highest growth and yield of peanuts. Peanut plants were planted in the Experimental Field of the Faculty of Agriculture, Bengkulu University from October to December 2018. The study was arranged in a Complete Randomized Block Design (RCBD) with 2 factors and 3 replications. The first factor is the planting distance of 40 cm x 20 cm; 40 cm x 30 cm and 40 cm x 40 cm. The second factor is the frequency of weeding consisting of no weeding, 1x weeding (age 2 WAP), 2x weeding (2 and 4 WAP), and 3x weeding (2, 4, and 6 WAP). The results showed that the interaction between the spacing of 40 cm x 40 cm and 2 x weeding can increase plant height. The spacing of 40 cm x 40 cm can reduce the population and dry weight of broadleaf weeds. The planting distance of 40 cm x 30 cm can increase the fresh weight of pods, pod weight/plot, and the highest dry weight of pods/plants. The frequency of weeding 2x can reduce the population and dry weight of broadleaf weeds; whereas weeding frequency 3x can reduce weed populations of grass and sedges- weeds, and dry weight of broadleaf weeds. The 3x weeding frequency can also increase the total number of pods/plants, pod weight/plot, and pod weight/plant.

Abstract

[POD BORER ATTACK ON SIX SOYBEAN VARIETIES AND THEIR EFFECTS ON YIELD]. This study aims to determine the level of pod borer attack on six soybean varieties and their effects on yields. This research was conducted from December 2017 to March 2018 in the Experimental Field of the Faculty of Agriculture, University of Bengkulu, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City. The experimental design used was a Randomized Complete Block Design (RCBD) with the treatment of six soybean varieties (Demas, Argomulyo, Dega, Ringing, Echo, and Dena I) and was repeated 4 times so that there were 24 experimental units. The results showed that the percentage of pod attack on the Demas, Argomulyo, Ringing, Gema, and Dena I varieties was classified as resistant, while the Dega variety was relatively resistant. Whereas the percentage of seed attack in all soybean varieties tested was classified as resistant. Argomulyo varieties have higher resistance to pod borer attack than other varieties because they produce the highest number of trichomes, and the lowest number of larvae per plant. Argomulyo variety produces the highest number of seed weight per plant, and the highest seed weight per plot. The echo variety produces the highest number of total pods, while the Dega variety produces the highest weight of 100 seeds.

Abstract

[MANURE APPLICATION AS A SOIL AMENDMENT TO PROMOTE GROWTH AND YIELD OF MELON (Cucumis melo L.) IN ULTISOL]. The application of manure may overcome soil fertility problems in Ultisol triggered by low pH, high P retention, high content of Al and Fe, and low CEC. The objective of this study was to determine the optimum dose of different manures applied to promote the best growth and yield of melon. The study was conducted from February to May 2019 at the Experimental Plot of the Faculty of Agriculture, University of Bengkulu. Three different manures (chicken, cow, and goat manure) were applied at 5, 10, 15, and 20 tons/ha. These treatments were arranged in Completely Randomized Design with three replications. The results show that the enhancement in chlorophyll content (SPAD index) was highest in plots solely applied with 20 tons ha-1 manure, whereas application of manure even at 20 tons/ha had no effects on melon yield and its components. Manure types solely promoted plant height, maturity date, fruit diameter, and soluble solid content (Brix). Melon growth and yield were not affected by combined application of manure type and dose. These indicate that application of manure types irrespective of the amount applied failed to solve fertility problems in Ultisol where melon was grown.

Abstract

[GROWTH AND YIELD OF  EIGHT SWEET CORN GENOTIPE ORGANICALLY GROWN IN SWAMPLAND]. Sweet corn (Zea mays saccharata Sturt) has a greater advantage than feed corn because of its early maturity and the price is more expensive. Recently, the need for sweet corn is higher than its production. To overcome these problems, it is necessary to expand the planting area by utilizing sub-optimal land such as swamps of low fertility. Agricultural intensification can be carried out through the use of organic materials to meet nutrient needs for growth and yield of sweet corn. Determination of varieties suitable for planting in sub-optimal land is also an effort to increase the productivity of sweet corn in swampland. This study aims to determine the potential of sweet corn genotype for organically cultivated in swampland. The material used in this study consisted of seven sweet corn genotypes and one comparative variety planted in experimental plots based on a Randomized Completely Block Design (RCBD) with three replications. The variables evaluated in this study were the growth, development, yield, and yield components of sweet corn. The results showed that the 8 sweet corn genotypes tested had significantly different in plant height, number of leaves, number of rows of seeds per cob, and yields per plot. Caps 17 B x Caps 22 and Caps 3 x Caps 5 are genotypes that have better growth than the comparative variety. On the other hand, the yield and yield components of the comparative variety was higher among the other genotypes tested.

Abstract

[TESTING THE CONCENTRATION OF FUNGI Beauveria bassiana (Bals.) ON MORTALITY OF POD BORER (Riptortus linearis F.) ON SOYBEAN]. To control pod borer (Riptortus linearis F). on soybean using chemical insecticides can cause pollution to the environment, kill non-targeted insects and evolve pest resistance. The use of entomopathogenic fungus is an environmentally friendly alternative, one of which is Beauveria bassiana. (Bals.). The purpose of this study was to obtain an effective concentration of Beauveria bassiana fungi that can kill the pod borer at the 50% level.  The study was arranged in a Completely Randomized Design (CRD) consisting of 6 levels of fungi and 3 replications, where each experimental unit used 2 polybags.  Each treatment unit used 10 pod borers. The concentration of B. bassiana consisted of 105, 106, 107, 108 and 109 conidia / mL, and without fungi application as a control. The results indicated that the treatment of B. bassiana concentration on R. linearis significantly affected the percentage of mortality and the number of infected R. linearis, but no significant effect on the time of death, number of pods/plants and percentage of the number of damaged soybean pods. The mortality of R. linearis is classified as low, that is, less than 50%.
