Abstract

Liquid organic fertilizer (POC) is a fertilizer that is applied to the leaves. The advantage of providing fertilizer through the leaves in a way that is more easily absorbed by plants, both macro, and micronutrient. The objectives of this research were conducted to 1) effect of the best POC concentration on the growth of pepper seeds; 2) the best time to fertilizer the pepper seedlings; and 3) the interaction between POC concentration and fertilization time on the growth of pepper seeds. This study used a Randomized Complete Block Design (RCBD) and was arranged in a factorial consisting of 2 factors in 3 replications. The first factor is the provision of liquid organic fertilizer (k) which consists of 3 levels (k1=5 cc/L water, k2=10 cc/L water, k3=15 cc/L water). The second factor is the time of fertilization (f) which consists of 3 levels, (f1=once every 5 days, f2=once every 10 days, f3=15 days). The data obtained were tested for analysis of variance followed with the least significant difference test (LSD) at the 5% level. The results showed that the concentration of POC was significant to the growth of pepper seeds, which was shown in the percentage of growth, root length, shoot dry weight, and shoot ratio. The best POC concentration is 15 cc/L water. The time of POC fertilization did not significantly affect the growth of pepper seeds. There was no interaction between POC concentration and fertilization time for pepper seedling growth for all variables.

Abstract

Peliburan is a term, that raised up the mud from the channels to the mound (called tukungan/guludan in local language) or raise beds as one of agronomic technics based on local indigenous of tidal swamplands farmers in South Kalimantan. Peliburan has many benefits for Siam Banjar citrus plant, namely creating a suitable microclimate so that it might be used to determine the appropriate time for ripening and harvesting of citrus fruits. The objectives of this study were to: 1) Determine the effect of  peliburan on ripening time of Siam Banjar citrus fruit based on the type of overflow in Barito Kuala Regency, 2) Determine the joint or simultaneous effect, and partial effect of peliburan on ripening time of the Siam Banjar citrus fruit in Barito Kuala Regency 3) Determine the direct effect of peliburan on ripening time of Siam Banjar citrus fruit in Barito Kuala Regency.     The recent study  used survey and observation methods. The research location was chosen in purposive sampling method by considering the type of overflow and farmers as respondents in the selected villages with high productivity of Siam Banjar citrus. The study was conducted in four district in Barito Kuala Regency, namely Mandastana District, Belawang District, Cerbon District and Barambai District. The data analysis used to determine the effect of Peliburan was multiple regression analysis with a dummy variable consisted of 7 variables, namely X1 : time of peliburan,  X2 :  shape of peliburan, X3 : diameter of peliburan (cm), X4 : height of peliburan (cm), X5 : spacing between peliburan (population), X6 : age of peliburan (years) and X7 : Soil temperature (oC).            The results showed that agronomic technics that is shape of peliburan, height of peliburan, spacing between peliburan and soil temperature had an effect on ripening time of Siam Banjar citrus fruit both at type A and type B overflow in Barito Kuala Regency. Simultaneously, all independent variables of peliburan had a significant linear relationship with the dependent variable that is ripening time of Siam Banjar citrus fruit in Barito Kuala Regency. Partially, at type A overflow, time of peliburan, diameter of peliburan, spacing between peliburan , height of peliburan, and soil temperature had a significant effect, whereas at type B overflow, time of peliburan, diameter of peliburan, height of peliburan, spacing between peliburan and age of peliburan  had a significant effect on ripening time of Siam Banjar citrus fruit. The dominant direct effect of peliburan at type A and type B overflow was the soil temperature and height of peliburan.

Abstract

Research on the intensity of leaf destroying pests, growth and yield of mustard (Brassica juncea L.) which was applied with several concentrations and frequency of galam (Melaleuca cajuputi) leaf solution has been carried out. The research was carried out at the Banjarbaru State Vocational School in March - June 2020 using a factorial completely randomized trial design. The first factor is the concentration of galam leaf solution application (20, 40, 60 and 80 ml/l) and the second factor is the frequency of application of galam leaf solution (1, 2 and 3 times a week). The control used in this study was without treatment which was placed separately outside the experimental design. The results showed that the interaction between the concentration level and the frequency of galam leaf solution had no effect on the intensity of leaf destroying pests and mustard plant yields, except for crude protein. The combination interaction between the concentration of 80 ml of galam leaf solution/l and the application frequency of 3 times gave the highest amount of crude protein. When compared with the control, the mustard plants that received the application of galam leaf solution showed a lower intensity of pest attack at 2 WAP with an attack intensity of 16.15%, as well as better growth and yields for plant height (3 and 4 WAP). leaves, total wet weight, crown weight, crude fiber and crude protein.

Abstract

This study aimed to 1) Analyze several Pseudomonas fluorescens group’s ability to induce resistance of chili plants to yellow curly virus infection. 2) Analyzing the ability of several Pseudomonas fluorescens groups to stimulate the growth of chili plants. The experimental design used a completely randomized design (CRD) with four levels of treatment, namely : control (untreated chili plants), SKM1 (chili plants treated with Pseudomonas fluorescens group SKM1), MP1 (chili plants treated with Pseudomonas fluorescein group MP1), and MM2 (chili plants treated with Pseudomonas fluorescens group MM2). Bacterial treatment was carried out by immersing chili seeds into a solution of the Pseudomonas fluorescens group with a concentration of 109 CFU/ml. Virus transmission in chili plants was carried out naturally in areas of high yellow curly disease epidemics. The results indicated that chili plants treated with Pseudomonas fluorescens groups SKM1, MM2, and MP1 had increased resistance to yellow curly virus infection and decreased percentage of attacks from yellow curly virus disease. Chili plants treated with Pseudomonas fluorescens group MM2 showed higher plant’s height and more branches than those treated with SKM1, MP1, and control. Chili plants treated with Pseudomonas fluorescens groups MM2 and MP1 have faster flowering time than those treated with SKM1 and control.
