Glycine max is a plant that can be used as a variety of food ingredients, such as tofu, tempeh, soy sauce. Glycine max production in North Kalimantan in 2017 has decreased production. One effort to increase Glycine max production is to use phosphorus fertilizer. Phosphorus fertilizer has the function of stimulating root growth especially at the beginning of growth, accelerating flowering, ripening of seeds and fruit. Therefore it is necessary to fertilize to increase Glycine max production. The purpose of this study was to determine the response of growth and yield of Glycine max plants to the dose of phosphorus fertilizer (p) and different varieties to determine the effect of the interaction between the dose of fertilizer with Glycine max varieties.This study used a factorial randomized block design with 8 treatments, 4 replications to produce 32 treatment units. The first factor is the dose of phosphorus fertilizer consisting of without using P fertilizer (P0), P fertilizer application 0.138 g per plant (P1), P fertilizer application 0.276 g per plant (P2), and P fertilizer application 0.552 g per plant (P3) . The second factor is Glycine max varieties consisting of Devon 1 varieties (V1) and Dena 1 varieties (V2). Analysis of data using variance with 95% confidence level and if significantly different, continued with DMRT test. The results obtained are that the dose of phosphorus fertilizer cannot affect the growth and yield of Glycine max plants in Dena 1 and Devon varieties 1. The use of Dena 1 varieties has a significant effect on the growth and yield of Glycine max plants in the treatment of plant height 3 mst (34.46 cm), 4 mst (46.35 cm), 5 mst (96.76 cm), main stem diameter 2 mst (0.33 cm) and plant seed weight (6.89 grams) and seed weight per hectare (1.1 tons / ha) . There was no interaction with the dose of phosphorus fertilizer and the use of varieties on the growth and yield of Glycine max plants in Dena 1 and Devon 1 varieties. Key words: Fertilizer, Phosphorus, Glycine max, North Borneo Kedelai merupakan tanaman yang dapat dijadikan berbagai macam bahan makanan, contohnya seperti tahu, tempe, kecap. Produksi kedelai di Kalimantan Utara tahun 2017 mengalami penurunan produksi. Salah satu upaya untuk meningkatkan produksi kedelai adalah menggunakan pupuk fosfor. Pupuk fosfor memiliki fungsi Merangsang pertumbuhan akar terutama pada awal-awal pertumbuhan, mempercepat pembungaan, pemasakan biji dan buah.oleh sebab itu perlu dilakukan pemupukan untuk meningkatkan produksi kedelai. Tujuan penelitian  ini adalah Mengetahui Respon pertumbuhan dan hasil tanaman kacang kedelai terhadap dosis pupuk fosfor (p) dan varietas yang berbeda mengetahui pengaruh interaksi antara dosis pupuk dengan varietas kacang kedelai. Penelitian ini mengunakan Rancangan Acak Kelompok Faktorial dengan 8 perlakuan, 4 ulangan sehingga menghasilkan 32 unit perlakuan. Faktor pertama yaitu dosis pupuk fosfor yang terdiri dari tanpa menggunakan pupuk P (P0), pemberian pupuk P 0,138 g per tanaman (P1), pemberian pupuk P 0,276 g per tanaman (P2), dan  pemberian pupuk P 0,552 g per tanaman (P3). Faktor kedua yaitu varietas tanaman kedelai yang terdiri dari varietas Devon 1 (V1) dan varietas Dena 1 (V2). Analisis data menggunakan sidik ragam dengan tingkat kepercayaan 95% dan apabila berbeda nyata dilanjut dengan uji lanjut DMRT. Hasil penelitian yang diperoleh adalah Pemberian  dosis pupuk fosfor tidak dapat mempengaruhi pertumbuhan dan hasil tanaman kedelai varietas  Dena 1 dan Devon 1. Penggunaan varietas Dena 1 berpengaruh nyata terhadap pertumbuhan dan hasil tanaman kedelai pada perlakukan tinggi tanaman 3 mst (34,46 cm), 4 mst (46,35 cm), 5 mst (96,76 cm), diameter batang utama 2 mst (0,33 cm) dan  berat biji  pertanaman (6,89 gram) dan berat biji perhektar (1,1 ton/ha). Tidak terjadi interaksi pada pemberian dosis pupuk fosfor dan penggunaan varietas terhadap pertumbuhan dan hasil tanaman kedelai varietas Dena 1 dan Devon 1. Kata Kunci: Pupuk, Fosfor, Kedelai (Glycine max), Kalimantan Utara

A field experiment was conducted to study the effect of different nitrogen and phosphorus fertilizer rates on the growth and yield tomato at Northwestern Zone of Tigray during 2016-2017 cropping season under irrigation condition. It  is  the  most  cultivated  and  high  market  value  of  vegetable crops  in  Tigray  Northern Ethiopia. However, tomato production is limited due to low fertility of soil and inappropriate fertilizer rate. Six different levels of nitrogen (0, 23, 46, 69, 92 and 115 kg N /ha) and six different levels of phosphorus (0, 46, 69, 92,115 and 138 kg P2O5/ ha) were used and laid out in randomized complete block design with three replication. (Melkasalsa) tomato variety was used as a testing variety. The current findings showed that the highest marketable tomato fruit yield (61.16 t/ha) were obtained in 115 kg N/ha (250 kg urea/ha) and 92 kg P2O5 (200 kg Di Ammonium Phosphate DAP /ha).  But, the profitable yield obtained was at N2P2 (46 kg N & 69 P2O5 kg ha-1) that is 100 kg/ha of Urea combined with 150 kg/ha of DAP yield was obtained 48.25 t ha-1 and the profit was 235502 birr per ha with the maximum Marginal Rate of Return of 26.16%. Therefore, 100 kg/ha of urea with 150 kg/ha of DAP was recommended for the growers to improve tomato fruit productivity in the study area.

Depletion of nitrogen and phosphorus in terraced hilly areas of Rwanda has lowered maize (Zea mays L.) production. Trials were carried out in 2017 and 2018 in four-year-old-terraced Lixisols and Acrisols of medium and high altitudes to determine effect of nitrogen and phosphorus fertilizer application rates on maize yields. A factorial arrangement of four levels of nitrogen (0, 60, 120 and 180 kg N ha-1) and phosphorus (0, 40, 80 and 120 kg P2O5 ha-1) in a randomized complete block design with 3 replications, was used. Results showed that combinations of 120 - 180 kg N ha-1 and 80 - 120 kg P2O5 ha-1 resulted in significantly (P less than 0.05) higher increases in plant height (45 – 60 % and 56 – 70 % over the control), stem collar diameter (63 – 74 % and 43 % over the control) and grain yields (3 times over the control; i.e. 6.40 – 6.46 t ha-1 and 6.02 - 6.12 t ha-1) in medium and high altitude sites. The optimum fertilizer rates are 176.6 kg N ha-1 and 96.2 kg P2O5 ha-1 in terraced Lixisols of medium altitude area. Land use needs to adjust fertilizer application to these optimum rates for enhanced maize yields in this area and other regions with similar agro-ecological characteristics. Further studies on integrated effects of N and P fertilizers are recommended.
