Abstract

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically non-significant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot -1 in 2014-2015 and 5.89 g pot -1 in 2015-2016), and stover yield (9.55 g pot -1 in 2014-2015 and 8.58 g pot -1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation. The Agriculturists 2017; 15(1) 156-169

丛枝菌根真菌对扁豆(Lens culinaris)耐氯化钠水平及生长和产量的影响

2014-2015年至2015-2016年，在加济普尔Joydebpur孟加拉国农业研究所土壤科学处的网棚进行了盆栽试验。试验设计为4个重复的因子随机完全区组设计。本研究旨在探讨不同浓度氯化钠(NaCl)处理下丛枝菌根(AM)对小扁豆萌发、产量及产量性状的影响。5个NaCl处理(0、1、2、3和4%)在孟加拉国小扁豆种子覆盖或关键脉冲作物播种前进行土壤处理，其NaCl水平为第一因子。第二个因素包括菌根和非菌根处理。在发芽率、产量和产量贡献性状方面，菌根植物均优于非菌根植物。随着NaCl浓度的增加，根际土壤发芽率、产量和产量贡献性状均显著降低(p<0.01)。接种菌根和NaCl对小扁豆发芽率、生长和产量的互作效应无统计学意义。NaCl 0% + AM处理的种子发芽率最高(2014-2015年为96.25%，2015-2016年为92.50%)，种子产量最高(2014-2015年为6.45 g, 2015-2016年为5.89 g)，秸秆产量最高(2014-2015年为9.55 g, 2015-2016年为8.58 g)。4% NaCl处理的发芽率、种子产量和秸秆产量最低。2014-2015年和2015-2016年，接种菌根可使种子产量平均提高31.85%和63.71%;2014-2015年和2015-2016年，接种菌根可使秸秆产量平均提高48.56%和63.55%。由此可见，接种菌根比不接种菌根能提高小扁豆的发芽率、生长和产量。农学家2017;15 (1) 156 - 169
