Abstract

This study aimed to geting information about the relationship among the characters and identifying characters agronomic direct and indirect influence on grain yield. Many as four varieties of soybean (Glycine max) included the local varieties as comparison was evaluated on dry land land in Manokwari, Sobey District, Village Sobey at MT I month from January to December, 2013. The experiment was conducted by using a randomized block design (RAK) non factorial, with three blocks as replication. The variable agronomic characters were observed terms of height, the number of productive branches, number ofpods per plant, number of empty pods per plant, total number of pods, and the results. Data were analyzed with simple correlation and continued with path coefficient analyses. The results based on both method of analysis, soybean varieties of high yielding varieties which had total number of pods and a high number of pods. Therefore, the total number of pods and number of pods were recommended to be used as selection criteria in order to obtain soybean varieties for high yield in dry land.

Abstract

Ancaman dan krisis pangan dunia yang menggejala secara global sejak awal 2008 memiliki kaitan sangat erat dengan perubahan iklim global. Penurunan produksi pangan di berbagai negara disebabkan oleh berbagai perubahan iklim antara lain peningkatan kadar gas rumah kaca (GRK), perubahan pola curah hujan dan kejadian iklim ekstrim, peningkatan suhu udara, kenaikan muka air laut dan rob. Berdasar tipe fotosintesis, tanaman dibedakan menjadi C3, C4,dan CAM.Pada makalah ini diperlihatkan pengaruh pemanasan global terhadap beberapa spesies tanaman C3, baik diukur dari produktvitas tanaman, kandungan klorofil akibat suhu tinggi, serta evapotranspirasi. Tanaman yang dibahas adalah Phaseolus radiatus, Glicine max L., Capsicum frutescens L., dan Solanum tuberosum. Pada tanaman kacang hijau, volume curah hujan bulan Mei sangat mempengaruhi produktivitas kacang hijau yang ditanam pada musim tanam ke dua (MT) di lahan kering di Kabupaten Pati.Besarnya nilai evapotranspirasi kedelai dipengaruhi oleh curah hujan.jika jumlah curah hujan tinggi maka evapotrasnpirasi juga tinggi. Laju evepotranspirasi tanaman kedelai di Malang dari tahun 1997 – 2011 terus meningkat. 1997 – 2001 rata-rata laju evapotranspirasi kedelai 3.21 mm hari -1, 2002 – 2006rata-ratalaju evapotranspirasi kedelai 3.29 mm hari -1, 2007 – 2011 laju evapotranspirasi kedelai 3.35 mm hari -1.Dampak perubahan iklim menyebabkan terjadinya.
