Saturated soil culture (SSC) technology appropriate to prevent pyrite oxidation on tidal swamps and has been proved to increase the productivity of soybean on non-tidal swamp. The objective of the research was to determine the growth response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip, Tanjung Lago, Banyuasin District, and South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main-plot of the experiment was water depth in the furrow consisted of 10, 20, 30, and 40 cm under soil surface (USS). The subplot of the experiments was soybean varieties consisted of Tanggamus, Slamet, Wilis, and Anjasmoro. No-watering was arranged out of the design as a comparison. The result showed that nutrient absorption of N, K and Mn by Tanggamus was higher than those of other varieties, except K, however K absorption of Tanggamus was not significantly different from Anjasmoro. P and Fe absorption of Tangamus tended to be higher than the other varieties, although statistically they were not affected by variety. However, technically and economically, 20 cm USS was the most appropriate water depth for soybean production at tidal swamps.

Twenty-nine soybean genotypes originating from various countries were evaluated on the tidal swamp of Indonesia to obtain information of agronomic character diversity as the soybean response to the environment and to obtain adaptive genotypes that can be used to develop soybean genotypes for the land. This study was conducted in a complete randomized block design with 3 replications. Diverse genetic backgrounds, countries and climatic regions of the 29 soybean genotypes were responsible for the difference in agronomic responses among the genotypes. All temperate and sub-tropical genotypes were able to produce seeds in the tropical type-B overflow tidal swamp. Adaptability based on seed yield resulted in 1 highly adaptive, 17 adaptive, 5 moderately adaptive and 6 non-adaptive genotypes. Adaptive and highly adaptive genotypes produced 1.56 - 2.58 tons ha-1 of seeds. Karasumame (Naihou), a subtropical genotype, produced the highest seed yield which was 65% higher than Indonesia average soybean productivity and 225% higher than soybean productivity with non-saturated soil culture technology on the tidal swamp. This study concluded that temperate and subtropical genotypes could be used as germplasm sources for soybean development in the tropical type-B overflow tidal swamp in Indonesia.

Aluminum is prevalent in soils of tidal swamps. Soybean is known to be very sensitive to aluminum stress and so when tidal swamps are converted to soybean cropland, considerable effort and expense are required to overcome Al toxicity in soybean roots. It is therefore necessary to determine at what time in early development soybeans can best endure aluminum stress and identify aluminum-tolerant cultivars. This study was conducted by testing the impact of aluminum exposure on three soybean cultivars (Tanggamus, Karasumame, and M652) (relative to no-exposure controls) at four time periods at 10, 20, and 30 days after planting. No significant effect of aluminum on root growth in the first five days after exposure was observed, but the toxic effects became evident after soybeans had been exposed to aluminum for 10 days. Soybean seedlings that experienced aluminum stress earliest (at 10 days after planting) were more negatively impacted by Al exposure than seedlings exposed later (e.g., 30 days after planting). Root growths of the three cultivars we tested in this study were all detrimentally impacted by aluminum exposure. However, the M652 cultivar was the most sensitive to aluminum exposure. We conclude that the critical threshold period for soybean root growth to succumb to aluminum stress is within the first 30 days after planting, whereas the tolerance to aluminum stress occurs only during the first 10 days of exposure.

Tomat merupakan tanaman hortikultura yang dapat dibudidayakan baik didataran tinggi maupun didataran rendah, tergantung varietas yang ditanam. Budidaya tanaman tomat sebagian besar masih secara konvensional yang biasa dilakukan petani, yang tidak lepas dari penggunaan bahan kimia (pupuk pestisida). Dimana hal tersebut dapat menimbulkan dampak negatif bagi kesehatan manusia. Alternatif lain adalah bertanam secara organic, sistem ini secara ekonomi menguntungkan dan secara ekologi tidak merusak.Penelitian dilaksanakan di Kelurahan Bunga Mas, Kecamatan Seluma Timur, Provinsi Bengkulu. Penelitian dimulai pada bulan Januari sampai bulan April 2021. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan satu (1) faktor, yaitu dosis pupuk bokashi kotoran sapi yang terdiri dari tujuh (7) tarap perlakuan dan tiga (3) ulang, setiap perlakuan terdiri dari lima (5) polybag, setiap polybag terdiri dari satu tanaman. Taraf dosisi pupuk bokashi kotoran sapi adalah P0 (kontrol pupuk NPK), P1(5 ton/ha), P2(10 ton/ha), P3 (15 ton/ha), P4 (20 ton/ha), P5 (25 ton/ha), P6 (30ton/ha). Hasil analisis sidik ragam dilanjutkan dengan uji BNJ 5% dan 1%. Peubah yang diamati tinggi tanaman, jumlah cabang, umur berbunga, umur panen, berat berangkasan basah, berat berangkasan kering, diameter buah, jumlah buah per/tanaman, berat buah pertanaman. Hasil penelitian menunjukkan bahwa perlakuan pupuk bokashi kotoran sapi berpengaruh sangat nyata terhadap berat berangkasan basah dan berangkasan kering, diameter buah, berat buah pertanaman dan berpengatuh tidak nyata terhadap tinggi tanaman, jumlah cabang, umur berbunga, umur panen, jumlah buah pertanaman. Perlakukan dosis pupuk bokashi kotoran sapi 10 ton/ha (P2) memberikan hasil yang terbaik.Â Kata kunci : Tomat, Dosis, Pupuk Bokashi Kotoran Sapi.

The investigation was done to use the allelopathical potency of tested weeds as botanical herbicide, to find the best concentration of weed extract, to find the effect of allelopathy to either weed of onion or the onion. The experiment was carried out in experimental land of Agriculture Faculty, The University of Hazairin, North Bengkulu and Laboratory of Agronomy for four months.The experiment was arranged factorially in a randomized block design with three replications. The kinds of extract weeds were Imperata cylindrica, Cyperus rotundus, Mikania micrantha and Ageratum conyzoides. Concentration was applied at 0%, 10%, 20%, 30%, and 40%.The result concluded that extract, concentration or interaction of the two not only affected insignificant to growth and yield of onion but also dry weight of weed. However, extract of Cyperus rotundus tent to suppress the weed around the onion. Concentration of extract showed inconsistent response to all parameters. It probably because the concentration was still low so that the effect of maintenance was dominant.

The objectives of the research were to find a variety well adapt in saline land and to know effect of saturated soil culture on growth and production of soybean. The research was conducted in saline land Bengkulu City from April to October 2012. The experiment was arranged in split plot randomized design. The main plot was culture technology consisted of conventional and saturrated soil culture. The sub plot was soybean variety consisted of tanggamus, slamet, wilis, Anjasmoro, Seulawah, and Sibayak. The result showed that growth and production of all varieties on conventional technology were lower than saturated soil culture. The well adapt Variety was anjasmoro.

The experiment was aimed to know the effect of BAP Plant Regulator to the formation and the development of Potatoâ€™s Micro Tuber. The treatment were 0; 2,5; 5; 7,5 mg/L BAP. The growing media was Murashige and Skoog (MS0). The result showed that BAP did not significantly affected the number, diameter, wet and dry weight of the tuber. However, the highest of number, diameter, wet and dry weight was found at the 7,5 mg/L BAP. The fastest formation of tuber was yielded in 5 mg/L BAP.

The experiment was conducted at Taman Yasmin VI Bogor in June 2009. The Objective of this experiment was to know the effect of liming dosage on soil pH of Desa Banyu Urip. The experiment was laid on treatment of liming dosage that consisted of 1 ton/ha, 1.5 ton/ha, 2 ton/ha, 2.5 ton/ha and without liming as a comparison. The result showed that the liming dosage increased soil pH up to 5.36 for 2.5 ton/ha. It is strongly recommended to use 2.5 ton/ha of lime to improve the soil fertility in Desa Banyu Urip.
