Adaptation Assessment of Introduced Soybean Varieties in Kabul Climatic Conditions

Seven soybean varieties evaluated for adaptation in Kabul climatic conditions in research farm of agriculture faculty, Kabul University. The soil of this research farm has silty loam texture with pH of 8.01 and EC of 0.17. The NPK levels of this soil are 8.3, 9.3 and 68.2 %, respectively. This research was conducted in Randomized Complete Block Design (RCBD) with three replications. The size of each plot was 6 m2, the space between each rows and plants was considered 40 cm and 20 cm, respectively. Germination percentage, days to flowering, days to maturity, plant height, number of pods per plant, number of seeds per pod, yield per unit area and morphological characters were targeted to measure. The concentration of leaf nitrogen was also measured using SPAD made in Japan and the result was significant. The highest yield performed in LD 11-2170 variety (2156.11 kg ha-1) but the lowest yield recognized in Kanpong 5 variety (1270 kg ha-1). The result of ANOVA was also significant. LSD was applied to compare varieties and LD 11-2170 and Daewon 3 were different from the others. The objective of this research was also yield performance. Based on the cluster, varieties classified into two main groups.
