In order to fulfill food needs, we need another food resources beside rice. Cassava (Manihot esculenta L.)Â is one of the sources food that substitutes the rice. Beside that, utilization of ultisols as cropland can support the efforts to fulfill food needs. This study was conducted to determine the effect of giving Phosphate Solubilizing Fungi (PSF) to one variety (Malang 1) and three accesions of cassava (Sutera, Kuning, and Bayel) on planting in ultisol land. The experiment were conducted with a split plot design, where the main plot consists of PSF and non PSF, while the subplot consists of 1 variety and 3 accessions of cassava. The results showed that addition of Phosphate Solubilizing Fungi (PSF) gives good effects to some characters such as plant height, number of leaves, number of tuber, and tuber weight if compared without PSF. Furthermore, only the Kuning accesion that shows the interaction with PSF for the number of leaves character.

One of the major constraints in Jatropha oil production is asynchronous fruit ripening, hence harvesting needs to be carried out accordingly which lead to drudgery. Therefore, an experimental study on the use of plant growth regulators was designed to induce synchronous fruits ripening. The study was conducted at the Jatropha Indocement Tbk PT Citeurep from January-June 2010. Test seed vi-ability and vigor was conducted in greenhouse Leuwikopo Experimental Garden, Bogor Dramaga. While the oil content test was conducted in the Department of Industrial Technology Testing Laboratory of Agricultural IPB. This research was conducted in two phases. In the first stage used factorial randomized block design. The first factor is the dose etephon 200,400,600,800, 1000 and 1200 ppm while the second factor is the time of application etephon ie 40 and 45 days after anthesis. The second phase also uses a factorial randomized block design. The first factor is the dose etephon 0,100,200, 300 and 400 ppm, while the second factor is the time of application ie 40 and 45 days after anthesis. Application of etephon at 200 ppm on 40 day after anthe-sis shorten the fruit maturation hence more synchronous fruit ripening in rainy season, but not in dry season when fruits ripened synchronously. The quality of the seed and kernel were not affected by etephon application. Keywords: Jatropha curcas, growth regulator, etephon, simultaneity of fruit maturity

Kedelai merupakan salah satu tanaman pangan yang cukup digemari oleh masyarakat Indonesia yang memiliki kandungan protein nabati yang cukup tinggi dan sangat bermanfaat bagi kesehatan. Salah satu upaya yang dapat dilakukan untuk meningkatkan produksi kedelai di Indonesia adalah dengan penggunaan benih bermutu. Kandungan protein dan lemak yang cukup tinggi didalam benih mengakibatkan benih cepat mengalami kemunduran (deteriorasi) selama proses penyimpanan benih. Salah satu upaya yang dapat dilakukan dalam mempertahankan atau mengembalikan mutu benih yaitu dengan teknik invigorasi. Invigorasi benih kedelai dilaporkan dapat meningkatkan performa dari benih kedelai. Beberapa teknik invigorasi benih kedelai di Indonesia diantaranya yaitu dengan hidrasi benih, perendaman dengan menggunakan larutan osmotic, priming, matriconditioning serta seed coating. Invigorasi benih dapat meningkatkan daya kecambah, indeks vigor, waktu muncul kecambah, kecepatan tumbuh, dan panjang akar kecambah.

One of the problems for phosphate fertilizing in ultisol soil is Al and Fe bounding and could be overcome by phosphate solubilizing bacteria activity.This study aimed to obtain the best dose of phosphate fertilizer with phosphate solubilizing bacteria for the production of upland rice seeds of the UBB1 PBM variety (Bangka Belitung University red rice 1) and its effect on seed quality. The research was carried out at the Research and Experimental Gardens – Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung, from August to December 2020. The design used was a split plot design, the main plot was phosphate solubilizing bacteria (treatment and control), and the subplots were fertilizers. phosphate (P1– quarter dose, P2– half dose, P2–three-quarter dose, P4– full dose). Seeds produced in the field were tested in the laboratory for viability and vigor. In the field, phosphate solubilizing bacteria (Burkholderia sp) can replace half the dose of phosphate fertilizer. This was indicated by the seed weight of plant-1 which did not differ between full dose + control and half dose + treatment. This fact was also identified in the viability and vigor of the seeds in laboratory testing. There was no significant difference in germination rate and vigor index between the two treatments. This finding shows that phosphate solubilizing bacteria can be applied for efficiency of phosphate fertilization and guaranteeing seed production and seed quality
