[APPLICATION OF LEAF FERTILIZER TO INCREASE THE GROWTH AND YIELD OF BAWANG DAYAK (Eleutherine palmifolia (L.) Merr)]. Bawang Dayak (Eleutherine palmifolia (L.) Merr) is a potential medicinal plant and required improved growth and yield through the application of appropriate fertilizers. This study aimed to increase the growth and yield of bawang Dayak by determining the optimum concentration and time interval of foliar fertilizer application. The experiment was arranged in a completely randomized block design factorial. The first factor was the concentration of foliar fertilizer, consisting of 0,1, 2, and 3 g/L. The second factor was interval application of foliar fertilizer, consisting of every day, every 3 days, every 6 days, and every 9 days. The results showed that bawang Dayak did not show a significant response to foliar fertilizers. However, there was an interaction between the concentration and interval of foliar fertilizer application which had a significantly different effect on plant height. The highest plant height occurred at intervals of 3-day foliar fertilizer application with a concentration of 3 g/L. The concentration of foliar fertilizer had a significant effect on the variables of plant height, bulb fresh weight, as well as the bulb numbers. All concentrations of foliar fertilizer (0-3 g/L), and time intervals of foliar fertilizer application (1-9 days) affected the same growth and yield response of Bawang Dayak.

[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.

[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.

[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.

[PATH ANALYSIS OF GROWTH CHARACTERS AND YIELD COMPONENTS WITH THE YIELD OF 15 GENOTYPES OF MAIZE HYBRID]. Determination of traits used as the selection criteria are based on the trait(s) that have a close relationship to the yield. The aims of this research were to measure the closeness of the relationship between morphological (growth and yield component) traits and crop yield, and to determine the trait that directly or indirectly affected on maize yield. The research was conducted in Rimbo Kedui’s Village, South Seluma Subdistrict, Seluma District, Bengkulu Province on May 2017 to August 2017. The experimental design used was a Complete Randomized Block Design (CRBD) in a single factor with 3 replications. The treatments were 15 maize hybrid genotypes, consisting of CT1, CT2, CT3, CT4, CT5, CT6, CT7, CT8, CT9, CT10, CT11, CT12, CT13, CT14, and CT15. The data were statistically analyzed by analysis of varians (ANOVA) with P(a=5%). The qualitative data were analyzed descriptively. The result of correlation analysis revealed that the yield of maize hybrids highly correlated to some growth and yield component factors. High-yielding maize hybrids were supported by higher ear diameter, plant fresh weight, plant dry weight, plant height, the number of seeds per ear. Plant dry weight became the variable that has the highest direct effect with positive correlation on the yield. The second highest rank was the number of seeds per ear with also a positive correlation value. Yield improvement of maize hybrid, therefore, can be obtained by fostering the plant total biomass and/or by multiplying the number of seeds per ear.

[THE EFFECTIVENESS Jatropha curcas (L.) LEAF EXTRACTS IN INHIBIT ROOT-KNOT NEMATODE (Meloidogyne spp.) INJURIES ON TOMATO]. One of the main problems in tomato cultivation is the attack of root purse nematodes (Meloidogyne spp.). Some methods of controlling Meloidogyne spp. which can be done including using plants as vegetable nematicides. This study aims to get the concentration of Jatropha leaf extract which is effective in inhibiting the Meloidogyne spp attack on tomato plants. This study used 48 plants, 24 plants for observation 35 days after planting and 24 plants for observation until the age of 77 days after planting. This study used a Completely Randomized Design (CRD) with the treatment of Jatropha leaf extract concentrations (0%, 10%, 20%, 30%, 40%, 50%), and repeated four times. The results showed Jatropha curcas extract in inhibiting the attack of root purse nematodes (Meloidogyne spp.) can maintain plant height, fruit number, fruit weight, and plant stover wet weight 35 days after planting, but no significant effect on stover wet weight plants 77 days after planting and dry weight of plant stover 35 days after planting and 77 days after planting. The concentration of Jatropha leaf extract tends to increase the concentration, the smaller the rate of infection and the population of Meloidogyne spp on tomato plants. The concentration of Jatropha leaf extract 35% - 45% is the optimum concentration in inhibiting Meloidogyne spp. on tomato plants.

The study was conducted from June to September 2017 at Jl. Al-Hikmah Mosque, Kandang Limun Village, Muara Bangkahulu Subdistrict, Bengkulu City with Ultisol soil type and altitude of 15 m above sea level. The study was arranged in Split Plot Design with two treatment factors and three replications. The first factor as the main plot was the time of giving of sludge 0, 2, and 4 weeks before planting, second factor as subplot was the application of each NPK dosage consisting of 3 treatment levels: 150 kg/ha, 225 kg/ha, and 300 kg/ha. The timing of sludge and NPK doses gave no significant effect on the growth and yield of sweet corn. The timing of sludge two weeks before planting gives better results on the number of leaves. NPK was giving no significant effect on all observed variables.

[THE INCIDENCE OF POD-BORER, Maruca testulalis Geyer (Lepidoptera: Pyralidae) IN EIGHT MUNG BEAN VARIETIES (Vigna radiata L.) AND ITS EFFECT ON YIELD]. Mung beans are an essential food crop in Indonesia, whose production is still increasing to meet domestic needs. However, the high attack of plant pests Maruca testulalis Geyer (Lepidoptera: Pyralidae) is one of the leading causes of the low production of green beans. The use of superior varieties is one solution to controlling these pests. This study was conducted to test seven superior varieties of green beans, namely Vima 1, Vima 2, Vima 3, Murai, Kenari, Kutilang and Seriti and one local variety against M. testulalis. The study used a completely randomized block design and was repeated three times. The results showed that the mungbean varieties Vima 1, Vima 2, and Vima 3 had M. testulalis attack with the lowest level of seed damage in sequence, namely 5.84%, 7.94%, and 6.39%. Even though the percentage of pod borers attack did not significantly affect the growth of all Balitkabi superior varieties and one local variety of mungbean planted, the Kutilang variety was the highest yield with seed yield rates that were as low as other low-attack varieties.
