An investigation entitled Agronomic package for container grown elephant foot yam was undertaken at College of Agriculture (KAU), Vellayani, Thiruvananthapuram, to standardize growth medium and nutrient and irrigation schedule for elephant foot yam grown in containers. The experiment was done by raising elephant foot yam var. Gajendra in plastic sacks of uniform size with 12 treatment combinations involving three growth media (M1 - soil : sand : FYM 1:1:1, M2 - soil : coir pith : FYM 1:1:1 and M3 - soil : coir pith : FYM 0.75:1.25:1), two nutrient schedule ( N1 – N and K in three splits and N2 – N and K in six splits ) and two irrigation schedule (I1 - irrigation once in three days and I2 - irrigation once in six days) with four replications in completely randomized design . Based on the results of the study, a cost effective agronomic package for container cultivation of elephant foot yam was formulated. Plastic sacks of uniform size filled with 9 kg soil + 3 kg coir pith + 3 kg FYM can be used as containers. Apply lime @ 10 g and neem cake @ 100 g sack-1 and bring the moisture content of growth medium to field capacity. Plant corm pieces of 250 g ( treated with Trichoderma – cow dung slurry and shade dried) in each sack. Apply the recommended dose of 100 : 50 : 150 kg NPK ha-1 for elephant foot yam through organic manures like groundnut cake, bone meal and wood ash. Apply 10 g of bone meal sack-1 as basal dose and 50 g of groundnut cake and 100 g of wood ash sack-1 in six splits at monthly interval starting from one month after planting. Irrigate the crop once in three days during non – rainy periods.
