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.
