Pengaruh Dosis dan Waktu Aplikasi Pupuk Hijau Lamtoro (Leucaena leucocephala (Lam.) de Wit) terhadap Sifat Kimia Tanah dan Hasil Tanaman Jagung (Zea mays L.) di Suco Mauboke, Distrik Liquiça Timor Leste
Abstrak: Corn (Zea mays L.) as
food, is a source of carbohydrate both after the rice, besides corn was also
used the livestock feed ingredients and raw materials industry. Low crop yields
at dryland farming areas is generally associated with poor soil physical andchemical
properties. The application of green lamtoro, at appropriate rate and time is
expected to be able to improve the soil fertility and in the end to increase
crop yields. A Field experiments was conducted atvillage Mauboke, district
Liquiça of Timor Leste, to know the effects of rates and time of application
green lamtoro on the soil chemical properties and the yield of corn. The
experiment was done from February until July 2016. A randomizedcompleted block
designwith two factors of treatment arranged factorially, was used in thisexperiment.
The treatment consisted of greenfertilizer lamtoro 5, 10 and 15 tha-1and times
ofapplication 1, 2, 3 and 4 weeks before planting. All treatment were
replicated three times. Results of experimentindicated that the interaction
between rates and time of application of green fertilizer lamtoro real effects of
soil N-total, number of plant and extensive index leaf, fresh brangkasanweight
plants, brangkasan oven dry weight plants. The heighest oven dry seed weight
was also resulted from the same rate 15 tha-1the highest 14,46% wish was notsignificantly.
The time of green fertilizer lamtoro of 4 MST the best improved fertility of
soilchemical on the rate of 15 tha-1 with the increase of C-organic of 37,90%
lowest 20,93%, Pavailable 76,27% lowest 26.58%, K-available 100,79% lowest
21,35%. The best rate ofgreenfertilizerlamtoro 15 tha-1highest 3.7 tha-1shelled
dry. The soil with similar soil condition with that ofthe experimentrecommended
that the utilizing of rate green fertilizer lamtoro 15 tha-1with time
application of 4 MST the increased production of corn crops.
