Germination and field emergence potential of soybean land races vs improved varieties under different sowing dates

Abstract

Poor seed quality resulting in the establishment of poor stand which is the major problem of production in the cultivation of soybean. The objectives behind study were to evaluate the standard germination, field emergence and field emergence index of the seeds obtained from three land races (Kulat brown, Kulat white, Mothi) and two improved varieties (NARC-II, Swat-84) of soybean sown at four different dates at monthly interval from April to July during 2004, 2005 at New Developmental Farm, Agriculture University Peshawar. Standard germination, field emergence and field emergence index were significantly affected by sowing dates and varieties. In addition, to field emergence and field emergence index were observed to be affected by years. Sowing dates x varieties interactions were found significant for field emergence only. Maximum germination (74.6 %), field emergence (60.2 %) and field emergence index (79.1) were recorded for seeds harvested from May, April and April planted crops respectively. Kulat brown exhibited maximum germination (79 %), field emergence (66.1 %) and emergence index (83.6). In land races, germination, field emergence and field emergence index were detected as higher by 39, 58 and 12 percent comparatively to improved varieties. It is concluded that land races have the potential to emerge in various environmental conditions contrasted with improved varieties of soybean.

Response of Bacillus megaterium and Bacillus mucilaginosus Strains on Growth and Nutrient Uptake of Soybean

“…As a result of its ability to adapt to diverse soil conditions and climates, as well as its nutritional value, soybeans have gained popularity in Central India. Soybean occupies approximately 6% of all agricultural land worldwide as the most widely cultivated oilseed crop [3]. As per [4,] soybean cultivation in India covers approximately 11.33 million hectares, and the potential production in 2019-20 is over 13.79 million tonnes.…”

Response of Bacillus megaterium and Bacillus mucilaginosus Strains on Yield and Quality of Soybean

“…Due to its adaptability to diverse soil conditions and climates, as well as its nutritional content, soybean is becoming increasingly popular in Central India. As the most widely cultivated oilseed crop in the world, soybean occupies around 6% of all agricultural land under cultivation [3]. According to [4] the soybean cultivation area in India is approximately 11.33 million hectares, with a potential production of over 13.79 million tonnes in 2019-20.…”

Response of Combined Application of Nutrient Levels with Microbial Strains on Crop Growth, Nodulation and Yield of Soybean

“…As a result of their adaptability to diverse soil conditions and climates, as well as their nutritional value, soybeans are becoming increasingly popular in Central India. Approximately 6% of all agricultural land is devoted to soybean cultivation, making it the world's most widely cultivated oilseed crop [3]. It is estimated that India will produce over 13.79 million tons of soybeans in 2019-20 on a cultivation area of approximately 11.33 million hectares, according to [4].…”
