Evaluation of different wheat cultivars under salinity stress
##plugins.themes.bootstrap3.article.main##
Abstract
A field experiment was conducted to study the response of different 11 wheat (Triticum aestivum L.) cultivars under saline condition and by applying saline irrigation water during rabi 2016-17 at Krishi Vigyan Kendra, Sri Muktsar Sahib (Punjab). Experiment site was chosen with high salinity condition (EC=1.87 dS/m) to check the response of particular cultivars in these conditions. The field was only irrigated with tube well water having very high EC (4630 micro mhos/cm). Results showed that the grain yield was recorded higher in KH 65 (5648 kg/ha), KRL 210 (5440 kg/ha), KRL 386 (5290 kg/ha) and DBW 246 (5048 kg/ha) as compared to lower grain yield recorded with KRL 384 (4353 kg/ha), KRL 19 (4423 kg/ha), KRL 370 (4538 kg/ha), DBW 248 (4608 kg/ha),WH 1316 (4838 kg/ha), DBW 247 (4860 kg/ha) and KRL 377 (4895 kg/ha). The experimental site was slightly saline in nature, so the cultivar KH 65, KRL 210, KRL 386 and DBW 246 are very suitable for the area as these were less affected due to salinity. Grain yield among these varieties were higher due higher number of effective tiller per unit area and due to large number of grains per ear. Whereas, KH 65, KRL 377 and KRL 386 also produced significantly higher straw yield from WH 1316, DBW 248, DBW 247, KRL 210, KRL 384, DBW 246, KRL 370 and KRL 19.
