Lowland swamps have enormous potential and have been proven to provide significant contributions as a buffer in the national food security system. Rice farmers in non-tidal swamplands of South Sumatra plant rice at the end of the rainy season, because they wait for the water to recede, and therefore rice plants are very vulnerable to submerged stress in the vegetative phase and drought stress in the generative phase. This study aims to obtain rice varieties that are adaptive to these conditions and superior to lowland swamp agro-ecosystems. The research was conducted at the Plant Physiology Laboratory and Green House of Department of Agronomy, Faculty of Agriculture, Sriwijaya University. In this study, reciprocal crosses were carried out between Inpago 5 and Inpara 8 rice varieties. Inpago 5 variety was used because it has tolerant characters to drought stress in the generative phase and also has high production in farmers’ nontidal swampland. Inpara 8 has a Sub1 gene so that resistant to submerged stress in the vegetative phase. The results showed that both varieties had different characters in their growth and yield. Both varieties were crossed reciprocally and the success of crossing was more than 50%. F1 plants will be backcrossed with their female parents to get BC1F1 plants, and then selected using the MABC method [foreground selection, phenotypic selection, and background selection]. From the results of the MABC selection process, there will be BC1F1 plants with the genome proportion close to the female parent and confirmed to have the Sub1 gene.

Due to its abundance availability, banana pseudostem has been considered as potential resource for organic fertilizer in order to decrease dependencay on synthetic fertilizers. Thus, this research was aimed to evaluate the application of liquid organic fertilizer originated from banana pseudostem on growth and yield of sweet corn. The experiment was carried out in Experimental Farm of Department of Agronomy, University of Sriwijaya from January to April 2016. It was resulted that all parameters observed showed better response to P 3 compared to other treatments. Furthermore, the application of banana pseudostem liquid organic fertilizer was believed could increase soil mineral nutrients content.

In the intercropping cultivation, pest problem becomes an important factor on reducing production. Control by using chemical insecticide should be done wisely otherwise there will be a negative effect to environment. An alternative strategy is by application of Bacillus thuringiensis-based bio-insecticide. The objective of this research was to investigate the effect of the B. thuringiensis based bioinsecticide on the presence of Aphis gossypii and Coccinellid predators on intercropping cultivation (cucumber and long bean). Research was conducted in experimental field in Sriwijaya University Indralaya Campus South Sumatra, from June to August 2018. The research was arranged by Completely Randomized Blocked Design, with three treatments and 6 replications. The treatments were application of B. thuringiensis based-bioinsecticide, chemical insecticide and non-application of both. Treatments were done once a week as well as observation of A. gossypii and Coccinellid predators. Sampling method used was visual control, hand picking, pitfall trap, and insect net. The results showed four species of Coccinelid were identified i.e. Cheilomenes sexmaculata, Harmonia conformis, Verania discolor and Coccinella repanda. Population of Coccinellid predators was the highest at application of B. thuringiensis based bioinsecticide eventhough A. gossypii was also high. B. thuringiensis based-bioinsecticide was an ecofriendly way to control insect.

The development of duku plantation in other regencies is required to enrich duku germplasms in South Sumatra. Banyuasin Regency in South Sumatra was chosen as research location for this study since many duku plantations are located in this area.This research was aimed to observe the correlation of vegetative and generative characters of duku accession in Banyuasin Regency.The research was conducted for 10 months in 2017 located in three areas of Banyuasin Regency, which are Banyuasin 1 (BA 1 ), Banyuasin 2 (BA 2 ) and Banyuasin 3 (BA 3 ) with 5 plants per area resulting in total 15 plants. Purposive sampling method was used to determine the samples. Variability analysis and the calculation for correlation among vegetative and generative characters then were performed. Results showed that the characters of duku accessions indicated positive and negative correlation. Fruit sweetness level, however, did not show any correlation with either vegetative or generative characters.

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.

Masyarakat Desa Tanjung Utara sebagian besar tidak memanfaatkan lahan atau pekarangan karena sering terjadi banjir secara periodik setiap tahun. Saat ini, Indonesia bahkan dunia sedang mengalami covid-19 yang tidak hanya membawa masalah kesehatan masyarakat, tetapi juga berimplikasi luas, seperti kelancaran distribusi pangan. Pemerintah melalui Kementerian Pertanian telah membentuk program Pekarangan Pangan Lestari. Program ini sangat tepat untuk diwujudkan di masa covid-19. Kegiatan ini bertujuan 1) Memberdayakan masyarakat untuk memanfaatkan pekarangan dengan menanam berbagai tanaman sayuran untuk pemenuhan gizi keluarga dan memberi penyuluhan tentang manfaat tanaman sayuran, 2) Mensosialisasikan program Pekarangan Pangan Lestari (P2L).  Melalui berbagai teknik budidaya yang dapat diterapkan dengan membuat demonstrasi plot (demplot) baik langsung lahan pekarangan maupun menggunakan metode-metode lain seperti small garden, hidroponik, vertikultur dan microgreens. Hasil kegiatan pengabdian telah meningkatkan pemahaman ibu-ibu  mengenai budidaya sayuran di pekarangan dan program pekarangan pangan lestari.
