ABSTRACT

Loss

of

corn crop yields due

to

competition with weeds approximately 40-50% To overcome the negative impacts, it is necessary to ^prepare land such as no tillage whrch is one of the alternatrves in the preparation of land for corn crops This siudy aims to evaluate groMh and produciion ot zea mays on weed management and land preparaiion rn three different places in sumatera utara.

This

^{study was conducted in Deli Serdang area, Karo area dan}

Simalungun area, Sumatera Utara The research used Randomized block Cesign non factoriai with 10 treatments and repeated 3 times The treatments were:

Tl

(soil tillage, 21 and 42 day after planting (DAP) ,lith _Paraquat application); T2 ((soil iillage, 2'1 and 42 day after ^planting (DAP) with Mesotrion + Atrazin (Calaris) application), T3 ^(soil tillage, 21 and 42 DAP with weeded)i T4 (soil titlage, 14 DAP weeded); T5 (soil tillage, no weed controlled); T6 (no soil

tillage, 21 and

42

DAP paraquat application);

T7

(no soil iillage,

21

and 42 DAP calaris application); TB (no soil tillage, 21 and 42 DAP weeded); Tg (no soil tillage 14 DAP weeded);

T1O (no soil tillage and no weed controlled) The result indicated that soll tillage and weed control in three drfferent palces in Sumatera Utara ^showed significant effect on the groMh and production variable such as leaf area where soil tillage 21 and 42 DAP with paraquat application was the highest in Deli Serdang and Karo area , 100 seeds weight where Simalungun area was the highest, and showed significant effect on variable production per plant in Karo area where paraquat and calaris application was the highest among other treatments Therefore, weed management and land preparation are important to increase groMh and production corn crop Key words: zea mays, weed, land, tillage.

lntroduction

The presence of weeds on corn crops decreases yield and seed

quality

The critical period of corn crops competes with weeds occurs on days 20 and 45, then also the critical periods of maize occur on days 80

to

150. The yield decrease depends on the type of weeds, density, duration of competition, and allelopathic compounds ^issued

by

weeds. Allelopathy

is a

chemical released

by

weeds against

the

staple crops causing

the

morphology

of its

leaves, which

is

filled with brown and white ^patches, stunted small plants, abnormally long roots. Physically weeds compete with plants in

terms

of

spatial use, light and chemically

in

lerms

of

utillzation

of

water, nutrients, essential gases

in the

allelopathic process. Competition may

take

place when the components

or

substances needed

by

weeds

or

cultivated plants

are at a

^limited

number, Iocated adjacent and together required (Sembodo,2010; Clay and Aquilar, 1998; Moenandir, 2010).

Tillage

is

not able

to

control

the

existence of weeds and even control

to

an increase in weed populations because during soil processing occurs

the

spread of weed vegetative organs such as stolon, rhizomes and roots are cut off by agricultural tools with the growing population of plants with weeds that directly reduce the yield of plants (Silawibawa et al., 2003). No tillage is a direct planting system without preceding the soil treatment. No tillage requires herbioides for previous weed control. No tillage began to be widely applied td farmers in central Java and Central Java after the rice harvest, farmers use

the

land

by

planting various crops. No tillage begins

with

the applioation of glyphosate-based herbicides to kill weeds (Mulyadi et al., 2007).

One of the pesticides

is

herbicide which in terms of time

of

herbicide can be divided into three namely, pre-planting herbioide, pre-growth herbicide, and post-grown herbicide. Pre-planting herbicides, applied to the land before or at the time the soil ^is treated but not

yet

planted. Pre-grew herbicides are given before weeds and plants grow. The effectiveness of herbicides will be maximal ^if the soil is not lumpy.

Postgrown

herbicides

are

sprayed

when weeds and plants have

^grown together.

ln

these circumstances

the

herbicide must be completely selective

in

the sense the word

can

kill weeds

but is

safe

for

cultivated plants. Selectivity

can

be enhanced by selecting suitable herbicides

for

^plants

and

in accordance with target weeds (Sasmita, 2005).

Mycorrhizae

a

form

of

mutualistic association between fungi

with

hlgh-level plant roots has a very wide spectrum both in terms of hosl plants, fungal mechanisms association, effectiveness, microhabitat and spreading. In this phenomenon fungi lnfect

and

colonize

the roots

without causing necrosis

as

common pathogenic fungal infections occur, and get regular nulrients from the plant. ln this case the fungus does not damage or kill its host plants receive mineral nutrients, while the fungus obtains carbon compounds from the result of photosynthesis of its host plants (Hanafiah, et a/., 2009).

Materials and Methods

ln order to study growth and production of zea mays on weed management and Iand preparation

in

three different places

in

Sumatera Utara,

an

experiment was conducted in Deli Serdang area, Karo area dan Simalungun area, Sumatera Utara, The research used Randomized block design non factorial with 10 treatments and repeated 3 times. The treatments were: T1 (soil tillage (ST), 21 and 42 day after planting (DAP) with Paraquat application); T2 ((soil tillage,

21

and

42

day after ptanting (DAP) with lvlesotrion

T3

(soil

42

DAP paraquat application); T7 (no soil tillage, 21 and 42 DAP calaris application); T8 (no soil tillage, 21 and 42 DAP weeded); T9 (no soil tillage ¹⁴ DAP weeded); T10 (no soil tillage and no weed controlled).

Land preparation. Land located cleaned. There were 30 plots, plot size 2 m x 3 m. The number of plants perplot had 55 plants and total plant had 1650 plants.

planting. The planting of corn seeds using tugal with a depth of 3 - 5 cm and spacing of 70 x 20 cm, one planting hole with two corn seeds and before first planted corn seeds in soak approximately 3 minutes to accelerate germination
