Climate change has a real impact on yields, seasonal shifts, cropping patterns of citrus siam banjar plantations (Citrus suhuensis) on tidal land. This research aims to analyze the relationship of the cropping patterns of surjan systems and climate extremes, as an effort to overcome climate change. The research was conducted in Batola in 2020 using written and oral survey methods. Data was extracted from farmers and related institutions. The respondents consisted of 45 men and 45 women. On each sub-district, 2 villages were surveyed according to tidal land type, namely Marabahan district (SP1 and SP2) type C, Mandastana subdistrict (Karang Indah and Karang Bunga) type B, and Cerbon district (Simpang Nungki and Kambat River) type A. The results showed that the chance of El-Niño was around 16.7-22.7%, while La-Niña reached 40%. The total extreme event was 67.8% of La-Niña side by side with El-Niño 15 times and generally El-Niño precedes La-Niña by about 40%. The total extreme event reached 62.7%. The productivity of citrus observations in 2015-2019 was 1.274 ton/ha and during El-Niño yields decreased by 0.05 ton/ha. Crops damaged by El-Niño in 20152016 were -2% of the area of 6,825.03 ha. More than 90% of farmers during extreme events applied a pattern of superior local-rice oranges-rice to tabukan and oranges-vegetables on mounds. Cropping patterns on tidal tidal land show a high level of resistance to climate change because they have not changed much for decades in both normal, dry, and wet climatic conditions. Keywords: El-Niño, extreme climate, La-Niña, siam banjar oranges, tidal land type A, B dan C

Edamame is a type of soybean that is consumed in an immature period. High demand for market exports especially to Japan, must be balanced by maximizing production with the use of marginal lands. One of marginal lands is peatland which might be used as growth media for edamame with Urea and Rhizobium biofertilizer application to support its growth. The recent study aimed at analyzing the combination of Urea and Rhizobium biofertilizer on the growth of edamame on peat soil media. The experiment was laid out in. Completely Randomized Design (CDR) with two factors. First factor was Urea dosage: p1 = 50 kg ha-1, p2 = 150 kg ha-1, p3 = 100 kg ha-1, p4 = 200 kg ha-1. The second factor was Rhizobium biofertilizer treatment: r0 = without Rhizobium biofertilizer and r1 = Rhizobium biofertilizer 8g kg-1 edamame seeds. All combination was repeated 3 times with 3 polybags of them, so that there were 72 plants in total. The results showed that there was a response between application of Urea and Rhizobium biofertilizer have a significant effect on the observed parameters, that is plant height (cm), number of trifoliate leaves (straind), shoot dry weight (g) and root dry weight (g). The result showed that the application of Urea 50 kg ha-1 with Rhizobium biofertilizer increased plant growth of edamame on peat soil.

Chili is an important commodity for most people, because of its function in terms of improving taste and appetite. Chili was seriously developed with the support of government funds for chili farmers. The development of chili plants, has enough obstacles, especially wich caused by plant disturbing organisms whether it is pests or diseases. The important organism that disturbs chili is wilting caused by Ralstonia solanacearum. In South Kalimantan, this disease reportedly attacked chilies spread in the districts of Banjar, Banjarbaru, Barito Kuala, Tapin, Hulu Sungai Tengah and Balangan with a cumulative attack area of 15,7 ha on 2017 (South Kalimantan BPTPH Database). This disease is important because of the nature of the attack which can cause the plants to wilt suddenly all part of the plant. Plants wich attacked by bacterial wilt cannot be cured. The effort that can be done in prevention before pathogens infect the plants (Sastra, 2004). One way to overcome this problem is biological control using biological agents from the type of antagonistic bacteria Bacillus spp, Pseudomonas fluorescens, and type of antagonistic fungus Trichoderma spp. From three biological agents proven able to inhibit the development of R. solanacearum in vitro which produces a zone of inhibition as wide as 13,5 mm for Bacillus spp, 22,25 mm for Pseudomonas fluorescens and 8,42 mm for Trichoderma spp. and can increase plant height growth, chili weight, root weight, wet weight, and dry weight plants. Trichoderma spp as the best biological agents for increasing chili growth and yield.

One of the causes of the declining productivity of rice is sheath blight disease caused by the mold Rhizoctonia solani Kuhn. Control of sheath blight disease that is often done by the farmers is by using chemical pesticides (fungicides), which caused environmental problems. One way to reduce the use of pesticides is to biological control by using antagonist bacteria. This study aimed at in vitro test of rhizobacteria in preventing the development of sheath blight disease in rice plants. This research was conducted in the Phytopathology laboratory of Plant Protection Department of Faculty Agriculture, University of Lambung Mangkurat Banjarbaru from March to May 2018. The experiment used a randomized block design with three groups consisting of eight types of rhizobacteria isolates: (r1) Pseudomonas aeruginosa (Barito Kuala), (r2) Bacillus megaterium (Hulu Sungai Tengah), (r3) Azotobacter sp. (Barito Kuala), (r4) Pseudomonas sp. (Hulu Sungai Selatan), (r5) Flavobacterium sp. (Tanah Laut), (r6) Bacillus bodius (Barito Kuala), (r7) Pseudomonas aeruginosa (Hulu Sungai Selatan), (r8) Necercia sp. (Tanah Laut). The results showed that all rhizobacteria have the ability to inhibit the development of R. solani with different percentages of inhibitions. Pseudomonas aeruginosa (Barito Kuala) was the most effective rhizobacteria in inhibiting the development of R. solani.

Sheath rot disease can affect the development of panicles so that it might reduce rice production and productivity. Nevertheless, the disease has not been widely discussed as a rice plant disease in South Kalimantan, thus it is necessary to conduct research on sheath rot disease related to the microclimate, in this case solar radiation as a part of the environmental factors for rice cultivation. The method used in this study was the quantitative survey on the ULM Action Research Program area, that is observation on samples and populations in the research area. Data were collected using the purposive sampling method, by using research instruments, namely three large plots measuring 140 m2 (10 m x 14 m) in 1 ha of land planted with rice. Each plot was divided into 15 subplots. Intensity data of sheath rot disease were taken from 5 samples in each subplot. The number of sample units taken in this study was 5 samples x 45 subplot = 225 samples. The weather station telemetry for measuring solar radiation (Wm-2) was installed at the altitude of 60 cm and 120 cm from the plant canopy. The highest disease intensity of sheath rot on stems was 0.45% and sheath rot on panicles was 12.72%. Solar radiation at the altitude of 120 cm has an effect to the intensity of sheath rot disease in panicle; that is, each increase of one unit of solar radiation (Wm-2) will reduce the intensity of sheath rot disease in panicles by 2.651%

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.

It is necessary to choose the right planting media for vegetable cultivation with a fertigation system. Modification of growing media at various intervals of nutrition can be recommended. The study aimed to 1) analyze the interaction effect of the modification of planting media at various intervals of nutrition on the growth and yield of belinjan tomatoes in the fertigation system, 2) analyze single the effect of each treatment, 3) determine the best combination of treatment. This research was conducted in a greenhouse by using a pot through the treatment of a Split Plot Design. The first factor as the main plot is the interval of nutrition (B) consisting of 3 levels: b1 (3 times a day), b2 (5 times a day), and b3 (7 times a day) and the second factor as a sub-plot is the modification of planting media (A) the ratio of burnt husks: manure: cocopeat the ratio consists of 4 levels: a0 (burnt husk), a1 (2:1:1), a2 (1:2:1), and a3 (1:1) 1:2). The results showed that there was an interaction effect of treatment on the main plot and sub-plots at intervals of nutrition and modification of planting media on the variable of Brix level of belinjan tomato. The single factor of modification of the planting media affected the average number of fruits per bunch, the relative growth rate of 59-73 days after planting and the root shoots ratio. Combination of treatment 7 times per day of the interval level of nutrition with 100% of the burnt husk media resulted in tomato Brix levels at an average level of (5.70) better than other combinations.

The same rainfall can cause different degrees of water stress depending on soil type, so the production response shown by plants can be different. This study is essential for growers, especially in predicting oil palm production based on water deficit for each soil type. The study was conducted on oil palm plantations in Central Kalimantan, Indonesia, with four soil types in 1,446.15 ha (40 blocks). The source of data collected from oil palm plantations included bunch number, average bunch weight, rainfall, and soil physical and chemical properties for the last 15 years (2007 - 2021). This experimental study used a two-stage cluster sampling method. The results showed that the best productivity, bunch number, and average bunch weight were found on Ultisols. The four soil types tested showed the same annual production distribution dynamic, but the response rate from each soil type showed differences. Entisols and Spodosols were more prone to drought stress due to water deficit than Ultisols and Histosols because of the differences in soil texture. Water deficit causes a decrease in oil palm productivity by 5 - 22% in the first year (Ultisols 12 - 22%; Entisols 12 - 22%; Spodosols 7 - 19%; Histosols 5 - 15%) and 1 - 8% in the second year (Ultisols 3 - 7%; Entisols 2 - 4%; Spodosols 5 - 8%; Histosols 1 - 5%) compared to previous years production. A decrease in oil palm productivity occurs at 3 - 5 months (bunch failure phase), 1 year (abortion sensitive phase), and 2 - 2.5 years (sex differentiation phase) after a water deficit appears.
