Cekaman rendaman merupakan salah satu masalah utama yang dihadapi dalam kegiatan budidaya padi di lahan rawa lebak. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian fosfor sebelum tanaman terendam yang diharapkan mampu meningkatkan ketahanan tanaman padi terhadap cekaman rendaman. Penelitian disusun menggunakan Rancangan Petak Terbagi (Split Plot) dengan varietas padi sebagai petak utama dan waktu pemberian fosfor sebagai anak petak yang masing-masing diulang sebanyak 3 kali. Varietas padi yang digunakan yaitu IR 42, Inpari 30, dan Ciherang. Waktu pemberian fosfor terdiri dari kontrol (P0), pemberian fosfor 3 hari sebelum perendaman (P1), 7 hari sebelum perendaman (P2), dan 14 hari sebelum perendaman (P3). Hasil penelitian menunjukkan bahwa Ciherang merupakan varietas yang paling terhambat pertumbuhannya akibat cekaman rendaman. Selain itu, perlakuan P2 (aplikasi fosfor pada 7 hari sebelum perendaman) menunjukkan hasil terbaik dibandingkan perlakuan lain yang secara signifikan ditunjukkan pada peubah luas daun, berat kering akar dan total berat kering tanaman pada 6 minggu setelah tanam atau 14 hari setelah perendaman. Data yang dihasilkan diharapkan mampu menjadi bahan pertimbangan dalam perbaikan teknis budidaya padi di lahan rawa lebak. One of the major constraints of rice cultivation in the non-tidal swamp area is submergence stress, which is considered could be managed by phosphorus application before submergence in order to increase rice tolerance towards submergence stress condition. Split plot design was used in this research with three replicates. Rice cultivars served as the main plot consisted of IR42, Inpari 30, and Ciherang. While for the sub-plot was phosphorus application consisted of P0 = control, P1 = phosphorus application 3 days before submergence, P2 = phosphorus application 7 days before submergence, and P3 = phosphorus application 14 days before submergence. Results showed that Ciherang was the most affected cultivar due to submergence stress. Furthermore, P2had better performance compared to other P treatments as significantly showed in leaf area, dry root weight, and total dry weight at 6 weeks after sowing or 14 days after submergence. The resulted data hopefully can be used as a consideration for swamp rice cultivation improvement effort.

Plant growth regulators have a significant impact on increasing both quality and quantity of plant yield for either mixed or separated application. The research was aimed to identify the effect of spraying plant growth regulators on duku flowers for fruit formation. The research was conducted from December 2014 to May 2015 in Sijacarana Local Technical Implementation Unit (UPTD) of Propagation, South Sumatra Province in Ogan Komering Ulu (OKU) Timur Regency. Duku tree used was 15 years old with the height around 10 meter. Complete Randomized Design was used with 3 replications where duku trees as the replicates. The spraying consisted of 3 single plant growth regulator treatments and 6 mixed treatments which were P1 (BAP 300 mg.L-1), P2 (NAA 300 mg.L-1), P3 (GA3 300 mg.L-1), P4 (BAP 100 mg. L-1 + GA3 200 mg.L-1), P5 (BAP 200 mg.L-1 + GA3 100 mg.L-1), P6 (BAP 150 mg.L-1 + GA3 150 mg.L-1), P7 (NAA 100 mg.L-1 + GA3 200 mg.L-1), P8 (NAA 200 mg.L-1 + GA3 100 mg.L-1), P9 (NAA 150 mg.L-1 + GA3 150 mg.L-1). Spraying was applied twice with a half dosage for each application. First application was performed about one month after flowering, and the second was one and a half month after flowering. Data were analyzed using analysis of variance and least significance difference at α 5%. The measurement of parameters were carried after harvest or 3 months after treatment. Results showed that plant growth regulator positively affected duku fruit formation. GA3 treatment then was considered as the best treatment as it had a unison in fruit maturity, the highest number of fruit per bunch, weight per fruit and total fruit weight per bunch, and had the lowest number of green fruit and seed per fruit.

[GROWTH AND HARVESTING FREQUENCY OF RED CHILI PLANTS WITH THE APPLICATION OF NPK FERTILIZERS CULTIVATED ON SUB-OPTIMAL LAND IN FLOATING CULTURE SYSTEM]. The low productivity of red chili in South Sumatra is mostly due to its cultivation was conducted in sub-optimal land that is less favorable for producing vegetable crops. This study aimed to evaluate growth and yield of red chili plants under suboptimal conditions using various doses of NPK fertilizer. The experiment was carried out from June to October 2022, at the water reservoir and experimental field (as a comparison) at the Faculty of Agriculture Universitas Sriwijaya, Indralaya, South Sumatra with an altitude of 10 m above sea level. Both experiments were arranged in a randomized block design with three replications and one factor in the group, namely NPK fertilizer doses (0, 5, 10, and 15 g/polybag). For the experiment in the water reservoir, each treatment was arranged randomly in a 200 cm x 100 cm bamboo raft (for each group). The results showed that the application of NPK fertilizer in floating cultivation did not increase plant height, number of leaves, shoot diameter, and harvesting frequency of red chili. It was concluded that the application of NPK fertilizer in floating cultivation did not increase growth and harvesting frequency of red chili.

Irmawati I, Priadi DP, Marlina M, Sodikin E, Ria M, Amelia CR. 2022. The application of NPK fertilizer through root infuse system on rubber plant (Hevea brasiliensis). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 793-799. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The application of fertilizer with an infuse system is one alternative to increase the efficiency of fertilization on rubber plants. Root infuse systems are considered advantageous because of the reduced risk of fertilizer loss due to leaching and evaporation. For this reason, this study was conducted to determine the efficiency of NPK absorption through a root infuse system in rubber plants (Hevea brasiliensis). The research was carried out from September to December 2020 at the ATC rubber plantation, Faculty of Agriculture, Sriwijaya University. This study used a randomized block design with 4 treatments consisting of N0 = control, N1 = 80 grams of NPK per plant, N2 = 100 grams of NPK per plant, N3 = 120 grams of NPK per plant. The observed variables included the volume of absorbed solution, leaf greenness level, and NPK content in plant leaves. Based on the results, it was concluded that NPK fertilization using root infuse system on rubber plants had a significant effect on the variables of the volume of absorbed solution at 3rd and 4th weeks, and leaf greenness level. The higher the concentration of solution, the slower and less solution was absorbed by the plant.
