Abstract

Oil palm (Elaeis quineensis Jacq) is a monocious plant whose pollination process requires pollinating agents such as insects (entomofily). E. kamerunicus insects is a palm oil specific pollinator insect. The existence of E. kamerunicus can be the value of Fruit set of oil palm bunches. This research aimed to study the behavior of E. kamerunicus pollinators on the flowering of oil palms, so that the information obtained was useful to evaluate the effectiveness of E. kamerunicus as pollinators. The purposive sampling method used to determine the sample plant, while observed the behavior of visit used the focal sampling method. Based on observation of the E. kamerunicus behavior, it was found that the duration of E. kamerunicus visited 17.87 seconds / flower, with the length of flowering activity on the first, second and third days each 3.29 minutes, 1.39 minutes and 0.57 minutes, then the visited rate of E. kamerunicus was based on female flowers and male flowers, it was 2.32 flowers / minute and 3.18 flowers / minute, while the visited rate of E. kamerunicus was based on male E. kamerunicus and female E. kamerunicus on male flowers 3.53 flowers / minute and 2.84 flowers / minute with a period of time to visited E. kamerunicus on female flowers at 09.00-13.00 WIB and the average number of individuals E. kamerunicus male and female on female oil palm flowers respectively 5 tails and 15 tails.

Abstract

Tomato (Lycopersicum esculentum L.) has a high market demand prospect. Low production of tomato plants can be caused by providing nutrients that are not optimal for plants. The growth and production of tomato plants can be optimized by providing various treatments, including the provision of appropriate and balanced nutrition using liquid organic fertilizer (POC) (NASA) and the right time interval for administration. This study aimed to determine the effect of NASA POC concentration and the time interval of administration on the growth and yield of tomato plants carried out at UPT 3 Agricultural Service, Kebomas District, Gresik Regency, East Java in December 2019 - March 2020. The study used a completely randomized design (CRD). two factors which are repeated three times. The first factor is the concentration of POC (NASA), consisting of four levels, namely without the provision of NASA POC (control) (P0), 1 ml / l water (P1), 2 ml / l water (P2), and 3 ml / l water (P3). The second factor is the interval of time of administration which consists of three levels, namely once a week (V1), once every 2 weeks (V2), and once every 3 weeks (V3). There was a very real interaction in the combination treatment of P3V2 on the height of tomato plants at the age of 40 days after planting (DAP) (68.06), 50 DAP (80.56), 60 DAP (86.06), and the number of leaves at 40 DAP (20.11. ), 50 DAP (26.56), 60 DAP (35.11).

Abstract

Red Beet (Beta vulgaris L.) is one of plant that are benefical to health. The purpose of this study was to determine the composition of the planting media and the concentration of liquid organic fertilizer that is appropriate for increasing growth and production of red beet plants. The study was conducted at the Greenhouse of the Faculty of Agriculture UPN "Veteran" East Java in December 2019 to March 2020. The research was a factorial experiment using a Completely Randomized Design (CRD) consisting of 2 factors and was repeated 3 times. The first factor is the composition of the planting media (M) and the second factor is the concentration of liquid organic fertilizer (P). Data were analyzed with ANOVA, if it had significant effect, it was continued with BNJ 5%. The treatment of the composition of the planting medium did not significantly affect all parameters of the observation, whereas the treatment of liquid organic fertilizer concentration significantly affected the observation parameters of plant lengths of 21, 28 and 35 hst, tuber weights and the wet weight of the stover of underground plants where the concentration of 6 ml/L gives the best results on red beet tubers.

Abstract

Kawista (Limonia acidissima L.) is a slow-growing annual plant whose causing decline population, necessary to be an effort to provide quality kawista seed on a large scale. The purpose of this research is to know the effect of PGPR concentration on the growth of kawista seed. Kawista seeds were planted in polybags placed in the experimental field of Agriculture Faculty UPN “Veteran” of East Java in November 2019 – February 2020. This research was compiled using a completely randomized design (RAL) one factor of PGPR concentration with 6 treatments (0, 5, 10, 15, 20, and 25) ml/L and each treatment was repeated 4 times. Parameters measured were increase in seedling height, increase in number of leaves, increase in stem diameter, increase the length of primary root, number of roots, and seed strength. Data were analyzed by F test and treatment was analyzed by BNJ at the level 5%. The result research showed no significant difference in the increase in seedling height, increase in number of leaves, increase in stem diameter,and seed strength. The response of kawista seed to PGPR concentration of 15 ml/L increase the length of primary root by 15,03 % and number of roots by 54,43 % compared without application of PGPR.

Abstract

Saline stress greatly affects maize crops starting from germination, growth and productivity. The application of rhizobacteria can affect germination and plant growth in saline soils. This study aims to determine the effect of indigenous rhizobacteria on germination and early vegetative growth of maize. The research was carried out in two stages, the first was screening isolates that were able to provide good germination under saline conditions. The second stage was the test for 8 rhizobacterial isolates from the first stage of the initial vegetative growth of maize in saline conditions. The experimental design used in the first stage was a completely randomized design, with 23 rhizobacterial isolates and 2 controls as treatments, repeated 2 times. In the second stage, a randomized block design was used, 8 treatments of rhizobacteria isolates and 2 controls, with 5 replications. The results of the research in the first stage obtained 8 rhizobacterial isolates that were able to give a germination percentage of ≥ 70% and isolate B311 gave a germination percentage of 90%. In the initial vegetative growth test, isolate B19 was able to provide better initial vegetative growth in saline conditions than other isolates.
