Abstract:
A field experiment was conducted at Agronomy Field unit, College of Agriculture, Shivamogga during kharif 2015-2016 and 2016-17 on sandy loamy soils to evaluate performance of promising Greengram varieties (Vigna radiata (L.) Wilczek) as influenced by planting density and fertilizer levels under rain fed situation in Southern Transitional Zone of Karnataka. Among three different varieties KKM-3 gave significantly higher grain yield (1056.91 kg ha-1) and straw yield (4107.01 kg ha-1) than PDM 84-647.17 178 (kg ha-1 and 2438.10 kg ha-1, respectively) and SBM-1 (746.55 kg ha-1 and 3097.03 kg ha-1, respectively. KKM-3 sown on 15th July recorded significantly higher grain and straw yield (1252.86kg ha-1 and 4912.04 kg ha-1 respectively) followed by sowing KKM-3 on 30th of July (878.82 kg ha-1and 3286.72 kg ha-1, respectively). Significantly higher grain of greengram was found with the recommended (30 ×10 cm) spacing (925.54 kg ha-1) followed by 45x10 cm spacing (883.42 kg ha-1). The grain and straw yield of greengram nutrition with 25:50:25 N P205 and K2O was 855.47 and 3498.70 kg ha-1 respectively, which increased to 953.50 and 3768.92 kg ha-1 due to125% higher recommended dose i.e. 31.25:62.5:31.25 kg N, P2O5 and K2O ha-1.
