Scholar, Department of Agronomy, DKS CARS Bhatapara, Chhattisgarh, India Production of newly released soybean varieties as influence by plant geometry and raised bed condition Gulshan Tandon and Dr. Rajendra Lakpale Abstract The present investigation entitled “Production of newly released soybean varieties as influence by plant geometry and raised bed condition” was carried out at Instructional Farm, DKS CARS Bhatapara during Kharif season of 2019. Experiment was laid out in Split Plot Design (SPD) with three replications. The trial was conducted in a split plot design with plant geometry as main plot and varieties in sub plot. The experiment comprised four different plant geometry viz. 30×10, 30×15, 45×10 and 45×15 cm row to row and plant to plant spacing and four different varieties viz. CG Soya 1, RSC 1052, RSC 1046 and RSC 1071 was planted in raised bed system. Optimum plant population is pre requisite obtain higher seed production and productivity of soybean. The result revealed that plant geometry 30×10 cm was to produce to significant higher growth parameters, yield attributing characters as compared to all other plant geometry. Variety RSC 1046 was recorded significant higher growth parameters, yield attributing characters and yield as compared to all other varieties. Keywords: Plant geometry, variety growth, yield attributes, and yield Introduction Soybean (Glycine max L. Merrill) is known as the “Wonder Crop and Golden Bean’’ of the 21st century. It is one of the oilseed crop second ranked among important oilseed crops of India. It is the only crop to be included in both the oilseed and the pulses categories. It is the most accessible, richest and easiest source of best quality protein. Due to the various applications of food and industrial products. It is an excellent health food containing soybean seed approximately 20% oil, 40% protein, 30% carbohydrates, 10% total sugar and 5% ash. (Iıta, 1992; Iıta, 1993) [10, 11] and its seed oil is rich in essential fatty acids (Acikgoz et al., 2009) [1] . This very useful crop is grown in many countries but land coverage in the United States of America is largest. India is the world’s third largest edible oil economy after the USA and China. In India, its cultivation in 2000 covers an area of 12.2 million hectares with production was 89.19 lakh tones in 2015 -16 and an average productivity of 922 kg ha-1 2017- 18 (Anonymous, 2018) [2] . In India the soybean production is comparatively lower than the world average (2484 kg ha-1). In India the major soybean producing states are Madhya Pradesh, Maharashtra, Rajasthan, Andhra Pradesh and Karnataka. In Chhattisgarh, soybean grown during the Kharif season occupies 159.59 thousand ha with an average yield of 975 kg ha-1 (Anonymous, 2018) [2] . Main soybean growing districts of Chhattisgarh are Bemetara, Dhamtari, Rajnandgaon, Durg, Mahasamund and Kabirdham. The soybean optimum plant population and plant geometry are the important factors for achieving higher soybean grain yields. The higher plant population creates plant to plant competition for water, light, nutrients and space resulting reduce the plant growth and poor yield. On the other hand, lower plant population is unable to exploit the available resources and these resources go wastes. Higher plant populations have led to increased plant height due to plant to plant competition for light. (Rajput and Shrivastava 1999) [16] . Materials and Method A field experiment was conducted at Instructional Farm, DKS CARS Bhatapara, during rainy season of 2019. The experiment was laid out in split plot design with three replication. The treatments was consisted of four varieties CG Soya 1, RSC 1052, RSC 1071 and RSC 1046, and four plant geometry(cm) 30× 10, 30×15, 45×10, and 45×15. Plant geometry in main plant and varieties in sub plot are adopted. Crop was sown in first week of July. Recommand dose of fertilizer applied 25 kg ha-1 of nitrogen, 60 kg ha-1 phosphorus and 40 kg ha-1 potassium. Crop planting was eight July and harvest in last week of October.
