Introducing alternative cultivars with enhanced water use efficiencies can help alleviate pressure on groundwater for crop irrigations in Mississippi (MS) Delta. A two-year field study was conducted in 2019–2020 to compare the water use efficiencies (WUE) of recently released and pre-released soybean {Glycine max (L.) Merr.} cultivars in maturity group (MG) III (‘P37A78’, ‘LG03-4561-14’), IV (‘Dyna-gro 4516x’, ‘DS25-1, DT97-4290’), and V (‘S12-1362’, ‘S14-16306’) in the MS Delta. The experimental design was a split-plot with cultivar as the first factor and the second factor was water variant irrigation (IR) and no irrigation (RF, rainfed), replicated three times. The MG IV cultivar Dyna-gro 4516x recorded the highest grain yield and WUE: grain yields were 4.58 Mg ha−1 and 3.89 Mg ha−1 under IR and RF, respectively in 2019, and 4.74 Mg ha−1 and 4.35 Mg ha−1 in 2020. The WUE were 7.2 and 6.9 kg ha−1 mm−1, respectively, in 2019 under IR and RF, and 13.4 and 16.9 kg ha−1 mm−1 in 2020. The data reveals that ‘Dyna-gro 4516x’ (MG IV), ‘LG03-4561-14’ (MG III), and ‘P37A78’ (MG III) are best adapted to the early soybean production system (ESPS) in MS Delta region for sustainable production for conserving water resources.

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.

Heavy metals are one of the most important pollutants released to the aquatic environment by the various industrial activities. The use of these wastewater for irrigation results accumulation of heavy metals in soil and plants. So, the present investigation deals with the various concentrations (0, 5, 10, 25, 50, 100, 200 and 300 mg/l) of copper and zinc on germination studies of soybean. The different concentrations of copper and zinc were used for germination studies. The seedlings were allowed to grow upto seven days. The studied morphological traits increased at 5 mg/l concentration and these parameters are gradually decreased with the increase of copper and zinc concentrations.
