The present investigation was carried out at the KVK Champhai demonstration farm to evaluate the effect of organic manures on the growth and yield performance of okra (Abelmoschus esculentus L). The treatments consisted of poultry manure at 5 t/ha, farmyard manure at 20 t/ha, neem cake at 2 t/ha, and control. All the organic manures were incorporated into the soil one week before sowing. The results revealed that application of organic manures significantly improved growth and yield attributes. Poultry manure recorded the highest plant height (31.7, 69.5, and 102.8 cm at 30, 60 days, and at harvest, respectively), number of fruits per plant (14.8), average fruit weight (15.3 g), and yield (10.1 t/ha), followed by FYM and neem cake, respectively, while control treatments showed the lowest yield and growth attributes. The results are in close conformity with the earlier reports by Darley et al., (1988) and Kumaran et al., (1998). The performance of poultry manure may be attributed to higher nutrient contents than other treatments. The same trend was observed by Amanullah et al., (2010). The study can conclude that poultry manure is the most effective organic manure among all the treatments in respect of plant growth and yield attributes.
