Evaluation of growth and yield attributes of potato (Solanum tuberosum L.) under agro-climatic conditions of Chhattisgarh plains

Abstract

An experiment was conducted at Research cum Demonstration Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during rabi season of 2019-20 to study the yield and yield attributing characters. Results indicated that K. Mohan (98.48%) was recorded for higher plant emergence per cent which was followed by K. Surya (96.36%), K. Jyoti (96.17%) and K. Ch-1 (96.07%). The plant height at 45 DAP (cm) ranged from 43.78 cm (K. Himalini) to K. Mohan (20.65 cm). The number of stem plant-1 ranged from 2.39 (IGP-2012-4) to 4.30 (IGP-2012-6). K. Sindhuri was recorded for significantly maximum number of leaves plant-1, plant vigour and fresh weight of haulm (423.62, 4.90 and 13.87 respectively kg/plot). K. Pukhraj was recorded for significantly maximum foliage senescence per cent (5.60) and it was statistically similar with K. Surya (5.50) and K. Ch-1(5.40). Plant vigour was recorded maximum for K. Nilkanth and K. Sindhuri (4.90,4.90 respectively) and minimum for IGP-2012-4 (4.1) and K. Jyoti (4.3). Average tuber weight varied from (IGP-2012-7) 41.78 g to K. Nilkanth (77.10 g). No. of total tuber (number per plot) ranged from IGP-2012-3(149.37) (number per plot) to K. Surya (298.08) (number per plot). K. Surya recorded maximum no. of total tuber 298.08 (number per plot), harvest index (68.75%) and total tuber yield (36.68 t/ha).
