Application Effect of Cow Manure Growth and Yield of Shallot in Inceptisols

ABSTRACT Intensive inorganic fertilization without applying organic materials enhances nutrient depletion. Application of cow manure is nessasary to improve soil fertility including Inceptisols. The experiment was conducted in sreen house of IAERI at Jakenan, Pati, Central Java province to determine appropriate dose of cow manure in providing better growth and yield of shallot cultivated in Inceptisols. Experiment was conducted from December 2014 till May 2015 using a randomized complete design (RCD) with 7 treatments (control, cow manure 5 , 10 , 15, 20, 25 and 30 tons/ha respectively) and 4 replications was applied which is The results showed more high application of cow manure will increase the leaf growth and more hight bulbs yield. The best yield show on treatment 30 t/ha cow manure based on the weight of the bulb yield. Manure application increase soil pH from 5.5 to 6.4. Economically dose of 20 tons cow manure per ha was the most efficient in terms of cost and bulb production
