Study impact of integration between cover crop and weed control treatments on weeds and improved sugarcane productivety

Abstract EN

A filed experiment was carried out at Al-Mattana Agricultural Research station, Agricultural Research Center, Luxor Governorate during 2015/16 and 2016/17 seasons, to study the effect of intercropping soybean (cover crop) with sugarcane crop, sole sugarcane and weed control treatments i.e.

(Stomp at 1.75 l/f.

hand hoeing twice at 25 and 45 days after planting and unweeded check) as the integrated weed control on fresh and dry weight of weeds (g/m2) and yield of primary crop (sugarcane) and secondary crop (soybean) which intercropping with sugarcane in natural infested soil by weeds.

The experiment was laid out in randomized complete block design (RCBD) under split plot arrogant with four replication, intercropping treatments was put in the main plots and weed control treatment in split plots with four replications for each treatment.

The infestation rates in field experiments were 8.79 ton/fed broad-leaved weeds, 8.66 ton/fed grassy and 17.45 ton/fed total weeds in 2015/16 season and 11.86 ton/fed broad-leaved weeds, 7.05 ton/fed grassy weeds and 18.91 ton/fed total weeds in 2016/17 season.

Intercropping soybean with sugarcane reduced fresh weight of total weeds at 75 days after planting about 56 to 59%, as well as improvement sugarcane yield attributes traits such as stalk length, diameter, number of stalk/fed and number of internodes/stalk which reflected on cane yield and sugar yield ton/fed.

in both seasons, compared to sole sugarcane Weed control by hand hoeing twice and Stomp at the rate of 1.75 l/f.

reduced fresh weight of total weeds at 75 days after planting by about 81 to 85% and 69 to 72%, respectively, compared to unweeded check, and increased stalks and top yield (ton/fed.) of sugarcane than unweeded check in average of both seasons.

The interaction effect between intercropping soybean with sugarcane and weed control treatments decreased were significantly fresh weight of total weeds, improved sugarcane yield attributes traits and cane and top yield (ton/fed.) of sugarcane compared to the sole sugarcane and without weed control.

Intercropping soybean and without weed control treatments reduced fresh weight of total weeds at 75 after day planting by 71.71 and 70.01% than sole sugarcane and without weed control treatments.

Hand hoeing twice reduced fresh weight total weeds at 75 after day planting by 93.78 and 87.91% with sole sugarcane and by 87.78 and 87.66% with intercropping soybean in 2015/16 and 2016/17 seasons, respectively, compared to sole sugarcane and without weed control.

Using Stomp at 1.75 l/fed reduced fresh weight of total weeds at 75 after day planting by 85.24 and 84.35% under intercropping soybean and by 75.45 and 80.42% under sole sugarcane in 2015/16 and 2016/17 seasons, respectively, compared to sole sugarcane and without weed controlFrom this investigate cane be recommended to sowing sugarcane fields intercropping with soybean legume crop as the animal feeding and weed control by hand hoeing twice or Stomp at the rate 1.75 l/fed to overcome on weeds problems and increased sugarcane productivity as well as increased gross income by productivity the second crops (soybean as a forage crop).
