“…Hal ini menunjukkan bahwa pemberian bakteri Azotobacter dapat meningkatkan tinggi tanaman jagung manis. Peningkatan tinggi tanaman disebabkan meningkatnya kadar nitrat (Gambar 5), menurut Utama, et al, (2008) tanaman menyerap nitrat lebih banyak dibandingkan amonium sehingga dengan peningkatan kadar nitrat, tanaman akan tumbuh dengan optimal. Unsur nitrogen berguna untuk merangsang pertumbuhan tanaman secara keseluruhan, merangsang pertumbuhan vegetatif dan berfungsi untuk sintesa asam amino dan protein dalam tanaman (Subowo, et al, 2010) Bakteri Azotobacter selain sebagai bakteri penambat nitrogen bakteri Azotobacter mampu menghasilkan substansi zat pemacu tumbuh yang dapat memacu pertumbuhan tanaman (Indriani, et al, 2011).…”

Azotobacter bacteria are non-symbiotic nitrogen-fixing bacteria that fix free nitrogen from the air. It is hoped that the nitrogen that has been fixed by Azotobacter bacteria can be used by plants to help corn grow. This research was carried out for 4 months, in the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak City, West Kalimantan Province, starting from preparing the planting media until the plants reached the maximum vegetative phase. Presentation of soil data analysis was obtained from the

“…Lingkungan pesisir seringkali tidak ramah dan beberapa faktor, seperti kelembaban tanah, nutrisi tanah, paparan angin, penguburan pasir, semprotan garam, dan salinitas tanah, kemungkinan membatasi pertumbuhan tanaman di bukit pasir pantai (Oosting & Billings 1942;van der Valk 1974;Barbour 1978;Maum 1994). Kelarutan garam (NaCl) yang tinggi adalah tekanan abiotik yang paling berpengaruh pada penurunan kuantitas dan kualitas tanaman (Utama & Haryoko. W. 2019).…”

Nepenthes or pitcher plant is one of the most exotic plants in the world. There are 82 species of Nepenthes in the world, and very few studies concerning salinity stress have been carried out. We have found one species of pitcher plant that was exposed to seawater, namely Nepenthes gracilis Korth. Sixty-eight individuals were exposed to seawater and the rest were not. Observing and measuring morphological characters and anatomical characters have been done to these two sample groups in order to reveal the adaptation expression to the salinity stress. Statistical analysis has also been carried out between both groups. Two samples showed that they have significant differences in the size of pitcher and leaf. The ones which were exposed to seawater had smaller pitchers and leaves than others. The exposed seawater pitcher plant also has thicker leaves and palisade than others. Additionally, salinity exposure tended to decrease the stomatal density. The possible reason for this pattern was discussed in this study.

“…Salinity in the growing media may cause the deficiencies in plants. The high Na content causes the plants to experience poisoning, resulting in damage to the permeable membrane of parenchyma cells [7]. Corn can survive in water salinity concentrations of up to 4000 ppm or the equivalent of 6.25 mS [8].…”

The air salinity in coastal area may contribute significant effects to the growth of plants. Physiological aspects of the plant growth of plants are important information to give optimal treatments during cultivation process. One potential plant cultivated on coastal area is corns. This study aimed to study the physiological response of corn's growth to certain air salinity condition during cultivation on coastal area, and to determine their salinity tolerance index. The research was conducted in a screen house at the experimental farm of the Faculty of Agriculture, Jenderal Soedirman University, from July to November 2021. The study was conducted using method of Randomized completely Block design factorial with two factors. The first factor is the corn varieties (Bonanza -9 F1 and Bisi-18), and the second factor is air salinity (0 mS, 6 mS, 12 mS, and 18 mS). The data were analyzed by using the Anova, and continue to 5% Duncan's Multiple Range Test (DMRT), when the result is significantly different. The observed variables were plant height, number of leaves, leaf area, root length, fresh root weight, root dry weight, stem fresh weight, dry stem weight, fresh leaf weight, dry leaf weight, and chlorophyll a and b, proline content, stomata density, widht stomata opening, fresh weight of corn cob, dry weight of corn cob, seed fresh weight, dry seed weight, and number of seeds. The results of the research showed that the tolerance index of the Bisi-18 corn was higher than Bonanza 9-F1 corn, which showing better physiology aspects of chlorophyll content and proline content. The 6 mS air salinity treatment reduced chlorophyll content at the end of vegetative and generative, leaf area, fresh and dry weight of seeds, and the number of corn seeds. The 18 mS air salinity treatment showed the highest proline content and decreased at 12 mS and 6 mS treatments. The interaction of treatments on proline content, stem fresh weight, and chlorophyll content showed that Bonanza 9-F1 corn plants with 18 mS air salinity treatment showed the highest yields. The tolerance level of the Bisi-18 corn showed that the plant was still tolerant at 18 mS salinity. In comparison, the Bonanza 9-F1 corn showed intolerant results at 6 mS air salinity.
