Effects of Planting Pattern on The Performance of Soybean Genotypes

Plant population is one of key factors in crops yield. The determination of optimum population per area unit needs to be accommodated through the planting space arrangement. This study aimed to know the performance of some soybean genotypes planted with both single and double row planting pattern. The research was conducted in Kendalpayak Experimental Field, Malang from February to May 2017 arranged in split plot experimental design with three replications. The main plot was planting space consisting of single row (40 cm x 15 cm) and double row (60 cm x 20 cm x 15 cm), while the sub-plot was the soybean genotypes consisting of 12 promising lines (Grob/IT-7-7, Grob/Pander-397-6, Grob/IT-17-1, IBK/Argop-276-3, Grob/Pander-395-2, Grob/Pander-428-1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, IBK/ Grob-296-10, Grob/IT-7-3, and Grob/IT-7-1) and 3 cultivars as comparison (Dena 1, Dena 2, and Grobogan). Each experimental unit was set in an area of 10.8 m2. Observation was performed on variables of plant height, number of fertile nodes, number of pods with three seeds, number of pods with two seeds, number of sterile pods, seeds dry weight, pod shells dry weight, weight of 100 seeds, and yields. The results of the research showed that each genotype performed different response to planting space depending on the characteristic of it. Yield obtained from double row planting space was 4.76% higher than that from single row planting space. There were 8 genotypes (Grob/IT-7-7, Grob/Pander-397-6, Dena 1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, Grob/IT-7-3, and Grob/IT-7-1) which were able to produce seeds 2.0 ton/ha, either planted in single row or double row planting space

Grob Symposium Considers Future of Graduate Education for Professional Educators

News release announces that top education professionals will visit the University of Dayton to attend the Grob Symposium dedicated to Dr. M. Audrey Grob

Grob aircraft construction: The G 110 flies

Description, specifications and test flight performance of the G 110 are provided. The G 110 completely incorporates modern GfK construction techniques which heretofore have been developed and perfected for the construction of sailplanes. The G 110 is a prototype of a GfK constructed motorized aircraft and shows much promise for the future of German aviation

Bioorthogonal Self-Immolative Linker Based on Grob Fragmentation.

A self-immolative bioorthogonal conditionally cleavable linker based on Grob fragmentation is described. It is derived from 1,3-aminocyclohexanols and allows the release of sulfonate-containing compounds in aqueous media. Modulation of the amine pKa promotes fragmentation even at slightly acidic pH, a common feature of several tumor environments. The Grob fragmentation can also occur under physiological conditions in living cells, highlighting the potential bioorthogonal applicability of this reaction

Penerapan Energi Surya dalam Proses Termal Pengolahan Hasil Pertanian

Baru-baru ini Gustav Grob (1996) mengingatkan lagi prediksi Club of Rome di awal tahun 1970-an bahwa bahan bakar fossil, yang sifatnya meneemarkan lingkungan, dan tak terbarukan kian berkurang keberadaannya dan dalam waktu dekat harus diganti dengan sumber energi terbarukan yang lebih bersahabat dengan lingkungan seperti sumber-sumber energi surya, biomassa, angin, hidro, dll. Ketergantungan kita atas bahan bakar fosil mungkin akan berlanjut sampai beberapa dekade lagi tetapi dalam jumlah yang jauh lebih kecil dari apa yang di konsumsikan sebelum tahun 2000 seperti terlihat pada Gambar 1 (Grob, 1996
