The aim of this research was to prove the giving fertilizer with dosage that produces seed production of soybean (Glycine max L.) 3 ton/ha and studying soil fertility through the nutrient indexs. The research was conducted in June 2017 until September 2017 at the market land of 1 Tanjung Sari, Medan Selayang sub-district. The research design is Factorial Random Design with two factors. The first factor is doses of fertilizer with the target of P1 = target 2 ton/ha; P2 = target 3 ton/ha; P3 = target of 4 ton/ha, second factor is treatment of soil nutrient index consist of B1 = 0,8 (100% less 20%); B2 = 0.9 (100% less 10%); B3 = 1 (100% standard nutrient index); B4 = 1.1 (100% plus 10%); B5 = 1.2 (100% plus 20%). The results showed that interaction of fertilizer based result target dose 3 ton/ha and nutrient index 0,9 (Urea : 45 kg/ha, SP-36: 90 kg/ha, KCL: 27 kg/ha, Phonska: 90 kg/ha, Dolomite: 900 kg/ha) reaches production of 2.86 tons/ha. The soil nutrient index found in B2 = 90% (fertilizer dose reduced by 10%) showed that the soil was fertile and gave the nutrient 10%.

The objectives of this study was to observe the effect of dolomite and NPK fertilizer application on growth,  yield and leaf phosphorus levels of soybeans (Glycine max (L.) Merril) due to the application of dolomite and NPK fertilizers. This research was conducted from June 2019 to December 2019, at the Experimental Station of Agriculture Faculty of University of HKBP Nommensen Medan in Simalingkar B Village, Medan Tuntungan District at an altitude of ±33m above sea level. Soil type Ultisol with Tex-sand 43.75%, Tex-dust 42.18%, Tex-clay 14.07; pH 4.63; cation exchange capacity (CEC) 14.64%, Ptotal 0.10%, N kjehldahl 1.9% K-exch 0.20%, Ca-exch 1.32%, Mg-exch 0.92%. This research was arranged in a factorial randomized block design (RAK) with 2 treatment factors, namely, the first factor was dolomite (D) which consisted of 3 levels, namely: D0 = 0 g/polybag, D1 = 11.2 g/polybag, D2 = 22.4 g/polybag. The second factor was NPK fertilizer (N), which consisted of 4 levels, namely: N0 = 0 g/polybag, N1 = 1.5g/polybag, N2 = 3 g/polybag and N3 = 4.5g/polybag.  Parameters observed were plant height, number of leaves, number of pods, number of filled pods, weight of filled pods, dry seed production per plant, dry weight of 100 seeds and leaf phosphorus levels. The results showed that dolomite application had a very significant effect on the number of pods, number of filled pods, weight of filled pods, dry seed production per plant, dry weight of 100 seeds, but had no significant effect on plant height, number of leaves and leaf phosphorus levels. The application of NPK fertilizer had a very significant effect on the number of pods, number of filled pods, dry seed production per plant, dry weight of 100 seeds but had no significant effect on plant height, number of leaves, weight of filled pods and leaf phosphorus content. The interaction of dolomite and NPK fertilizer had no significant effect on all observed parameters.

Byker, H. P., Soltani, N., Robinson, D. E., Tardif, F. J., Lawton, M. B. and Sikkema, P. H. 2013. Control of glyphosate-resistant Canada fleabane [ Conyza canadensis (L.) Cronq.] with preplant herbicide tankmixes in soybean [ Glycine max . (L). Merr.]. Can. J. Plant Sci. 93: 659–667. Glyphosate previously provided excellent control of Canada fleabane; however, with the evolution of glyphosate-resistant (GR) Canada fleabane in Ontario, alternative herbicides must be identified for control of this weed in soybean. The objective of this study was to identify preplant herbicide tankmixes that provide effective control of GR Canada fleabane. A total of 12 field trials were completed over a 2-yr period (2011, 2012) in fields previously confirmed with GR Canada fleabane. Preplant tankmixes of glyphosate (900 g a.e. ha−1) plus saflufenacil (25 g a.i. ha−1) or saflufenacil/dimethenamid-p (245 g a.i. ha−1) provided greater than 87% control 4 wk after application (WAA) across all sites. Glyphosate (900 g a.e. ha−1) tankmixed with metribuzin (1120 g a.i. ha−1), cloransulam-methyl (35 g a.i. ha−1) or flumetsulam (70 g a.i. ha−1) provided 78 to 99% control 8 WAA. Control of GR Canada fleabane prior to soybean emergence is essential as currently there are no herbicides that provide acceptable control in-crop. Because of the lack of in-crop options, spring residual herbicides may be required for season long control in regions where Canada fleabane emerges throughout the year to reduce Canada fleabane seed production and populations in subsequent years.

Glycine Max L

The legume seed coat is the site of sucrose unloading and the metabolism of imported ureides and synthesis of amino acids for the developing embryo. The cell types directly responsible for these functions in the seed coat are not known. We recently described a convex layer of tissue on the inside surface of the soybean (Glycine max L. Merr.) seed coat that was termed “antipit” because it was in direct opposition to the concave pit on the abaxial surface of the cotyledon. Cone cells of the antipit contained numerous hypertrophied Golgi apparatus and laminated rough endoplasmic reticulum common to actively secreting cells. The initial report by Dzikowski (1936) described the morphology of the pit and antipit in G. max and found these structures in only 68 of the 169 seed accessions examined.

Penelitian tentang pengaruh pemberian Pupuk organik cair (POC) asal limbah tumbuhan terhadap serapan hara N dan P serta produksi tanaman kedelai (Glycine max (L) Merrill) di lahan gambut telah dilaksanakan di kampus II Unisi Fakultas Pertanian Jl. Lintas Propinsi Parit 01, Desa Pulau Palas, Kecamatan Tembilahan Hulu, Kabupaten Indragiri Hilir Propinsi Riau. Dimulai dari bulan Agustus sampai bulan Oktober 2013. Tujuan dari penelitian ini untuk mendapatkan POC asal limbah tumbuhan yang terbaik untuk serapan hara N dan P serta produksi tanaman kedelai di lahan gambut. Penelitian ini menggunakan rancangan acak kelompok (RAK) faktor tunggal dengan 7 perlakuan dan 4 ulangan, 2 tanaman dijadikan sampel. Perlakuan dosis POC limbah tanaman pisang dan POC limbah sayur kol yang diberikan yaitu 0 L/Ha, 200 L/Ha, 400 L/Ha dan 600 L/Ha. Parameter pengamatan yaitu : serapan hara N dan P pada fase awal generatif, tinggi tanaman, jumlah bintil akar, polong hampa, produksi perplot, berat 100 biji dan brangkasan kering. Data pengamatan dianalisis dengan sidik ragam (ANOVA) dan dilanjutkan dengan Uji Lanjut Tukey HSD pada taraf 5%. Berdasarkan penelitian yang telah dilaksanakan dapat disimpulkan bahwa pemberian POC asal limbah tumbuhan tidak berpengaruh nyata terhadap serapan hara N dan P, tinggi tanaman, jumlah bintil akar, polong hampa, brangkasan kering tetapi berpengaruh nyata terhadap produksi perplot dan berat 100 biji.
