Soybean Growth and Yield With Application of Phosphate Fertilizer and Organic Matter

Abstract

Soybean is useful for tofu, tempe, soy sauce and soy milk. The effective use of fertilizer and organic application can increase soybean productivity. The objective of this research was to study the growth and yield of various soybean varieties on application of phospate fertilizer and organic matter. This research was conducted in North Binjai and Research and Technology Laboratory Agriculture Faculty Universitas Sumatera Utara, Medan on May-September 2016. The method used Randomized Block Design with 3 factors. The first factor is soybean varieties consisting of: (Argomulyo, Dering, Dena, Kaba, Gema, Grobogan and Wilis), fertilization of phosphate (control and 150 kg/ha) and organic material application (control, Blotong 10 ton/ha and POEFBC/Palm Oil Empty Fruit Bunches Compost 10 ton / Ha). The results of this research showed that the seven varieties of soybean had characteristic differences on shoot dry weight, age of flowering, age of harvest, phospate uptake and dry weight of 100 seed. The longest flowering and harvesting age is obtained in Wilis, while the shortest age is Grobogan. The highest uptake of P in Argomulyo with treatment without organic matter and phospate fertilizer. Kaba variety with blotong treatment has the highest dry seed weight.Keywords : Organic Matter, Phosphate Fertilizer, Soybean Varieties

Peluang Dan Tantangan Pemanfaatan Produk Hayati Di Perkebunan Kelapa Sawit

“…Pengomposan produk sampingan pabrik kelapa sawit untuk pemupukan blok komersial dapat meningkatkan daur ulang nutrisi, mengurangi biaya pemupukan, meningkatkan efisiensi nutrisi melalui pelepasan yang lebih lambat dan meningkatkan kualitas tanah dari sudut pandang fisik dan biologis (Baron et al, 2019). Penggunaan kompos juga dapat dikaitkan dengan mitigasi perubahan iklim (Nasution et al, 2014), dengan menghindari kondisi anaerobik. Tandan kosong kelapa sawit dari pabrik kelapa sawit telah banyak dimanfaatkan untuk produksi pupuk organik dan praktik ini juga mengurangi volume TKS hingga 50% (Chavalparit et al, 2006).…”
