“…In other words, the physiological effectiveness of maize crop to partition the dry matter into its cost effective (grain) yield than generation of whole-plant biomass increased under ZT and RT compared to CT. These results are not in line with the findings of [48] who stated that higher harvest index was observed where conventional tillage was applied compared to minimum tillage.…”

Different tillage practices are used for maize cropping in Libya. Yet, the effects of these practices on soil physical properties and maize growth and yield are not known. The objective of this study was to evaluate the effect of different tillage practices on soil physical properties and maize growth and yield in Libya. A field experiment was conducted in 2009 and repeated in 2010 using three tillage practices (conventional tillage (CT), ridge tillage (RT) and zero tillage (ZT)). Data about soil physical properties (penetration resistance (PR), bulk density (BD), total porosity (TP) and saturated hydraulic conductivity (Ks)) across soil depths, maize growth components (plant height, number of leaves, leaf area index and dry root weight) at 60, 75 and 125 days after planting, and maize yield (grain and stover) at harvest were collected and statistically analyzed in both years. To evaluate the effects of the tillage practices economically, the tillage operation cost and production cost were calculated. The results showed that at the surface layer (0-20 cm), CT had lower PR and lower BD, but higher TP and Ks compared to RT and ZT. At 20-40 cm and 40-60 cm depths, the lower PR and PD and higher TP and Ks were under ZT and RT compared to CT. All maize growth parameters at different times were highest for CT followed by RT and lowest for ZT. The CT practice presented the highest grain and stover yield followed by RT and ZT. However, harvest index was higher where ZT was applied. While tillage operation costs were the highest for CT followed by RT and ZT, the production costs were the highest for ZT followed by RT and CT. In general, the CT practice produced higher maize growth and yield, lower production cost, and higher tillage operation cost than those are planted using RT and ZT practices.

“…Maize planted under deep tillage and mulch obtained highest vegetative and root biomass probably because deep tillage resulted into good soil texture whereas, mulch conserved moisture for crops. In support of this results, Shahid et al (2016) reported highest plant biomass of maize under deep tillage. Similarly, Hou et al (2012) recorded an increase in plant biomass of maize under mulch.…”

“…In recent studies, Shahid et al (2016) reported highest vegetative biomass harvested on maize planted under deep tillage while lowest biomass was recorded from minimum tillage. Memon et al (2013) found that deep tillage yielded high production of biomass in maize, and improved essential nutrients required by livestock.…”

A field trial was conducted to determine the effect of tillage and mulch practices on the biomass response of cereal maize and soybean, lablab and grazing vetch which are legumes, when planted as fodder crops. The experiment was conducted using split-plot design with three replications. The main plot treatments were two mulch levels (Mulch and No-Mulch). The mulch was maize straw left from previous cropping season. The subplot treatments were minimum tillage (0.2 m) and deep tillage (0.35 m). The parts of the four crops quantified were leaf, stem and roots. The combination of deep tillage and mulch practices resulted in significant (P<0.05) increase in the leaf, stem and root biomass of maize and, soybean, lablab and grazing vetch. Minimum tillage and no-mulch combined depressed (P<0.0.5) the leaf, stem and root yield of maize while, for soybean, lablab and grazing vetch there was no definite trend of significantly (P<0.05) depressed biomass for the leaf, stem and root yield under minimum tillage and no-mulch, and deep tillage and no-mulch. There was low correlation and positive significant relationship between leaf, stem and root and legume crops whereas, maize had a high correlation relationship with its biomass parameters. It is recommended that maize, soybean, lablab and grazing vetch can be grown as forage crops under combined deep tillage and mulch practices in the Foothills agro-ecological zone of Lesotho to obtain enhanced biomass.

“…The operation of rotavator destroyed the weeds that provided more favorable environment for crop plants to efficiently utilize the available soil moisture, nutrients, space and solar radiation. Our results are in line with those of [26,27]. Among weed control methods, significantly highest biological yield was obtained from treatment of hoeing at 15, 30 and 45 DAS followed by the treatment of hoeing at 15 and 30 DAS which was statistically similar with the application of herbicide i.e.…”

To study the impact of different tillage practices and weed control methods on weeds growth, phenology and yield of maize, an experiment was conducted at Agronomy Research Farm of The University of Agriculture Peshawar during summer 2016. The study was performed in randomized complete block design (RCBD) with split plot arrangement having four replications. Tillage practices (chisel plough + rotavator, mouldboard plough + rotavator, cultivator + rotavator and rotavator) were assigned to main plots while weed control methods (control, hoeing 15 days after sowing (DAS), hoeing 15 and 30 DAS, hoeing 15, 30 and 45 DAS, and herbicide i.e. Nicosulfuron) were assigned to sub-plots. Results revealed that treatment of chisel plough + rotavator had induced significantly early days to tasseling, silking and physiological maturity and produced maximum grain yield and biological yield as compared to other tested tillage practices. Minimum weeds m-2 and weeds fresh weight at 60 DAS was recorded from the treatment of chisel plough + rotavator. Among weed control methods, the treatment of hoeing 15, 30 and 45 DAS delayed days to tasseling, silking and physiological maturity and resulted in higher grain yield and biological yield. Hoeing 15, 30 and 45 DAS drastically reduced weeds m-2 and weeds fresh weight at 60 DAS. It is concluded that chisel plough + rotavator and hoeing at 15, 30 and 45 days after sowing (DAS) significantly improved yield of maize crop.
