A fi~ld study consisting of four replications and seven different
cultural method of maize-weed control practices (such as one hoeing
without pulling of weeds as .1st weeding, mulching immediately after
sowing of maize (zea mays) with rape seed (Brassica juncea vat.
toria) straw and wheat {Triticum aestivum) chaff at 10 ton/hli,
hoeing and earthing up as 1st and 2nd weeding by removing weeds,
hoeing and earthing up as practiced by farmers, hoeing twice as ls~
and 2nd weeding by removing weeds but without earthing up and hoeing
twice only without removing weeds and earthing up as 1st· and 2nd
weeding) was conducted at NMRP Rampur in sandy loam soil under
maize-rape seed system in 1996/97 with the objective of: (i) to fin~
out the responses of different cultural method of maize weed control
practices on. yield and agronomical components of maize (ii) to
study the effect of weed control practices on grain yield of maize
and rape seed and {iii) to find out economically feasible cultural
practices of ~aize wcled control. Of the agronomical and yield traits
of maize sucp as ear height, plant height, 50% silking DAS, unfilled
ears, LA!, ear number and plant population none of the parameters
were recorded statistically significant. Grain -Yield of both maize
~drape seed wer5 also recorded nonsignificant. Weed parameters .of
number of weeds/m 1 day before 1st weeding (20 DAS} was observe~
nonsignificant but the other parameters such as number of weeds/m
before top dressing (37 DAS} and DM% of weeds were observed
significant. It was visualized from t.he experiment that all the 6
cultural practices of maize weed control were comparable to farmer's
practice of maize' weed ·. control. Mulching with wheat chaff at 10
ton/ha, farmer's practice of weeding and earthing up and two hoeing
as the 1st and the 2nd weeding. wi thqut removihg weeds showed N
balance in the systeltl. SoH pH was unchanged due to treatments
effect. Organic matter perc.entage was reduced from 0.06 to 0.31 due
to maize-rape seed pattern.
