Tillage is the physical manipulation of soil to improve physical soil conditions. In Pakistan, various tillage technologies such as primary and secondary tillage affect plant growth, incorporate organic matter residues into the soil, eradicate weeds, and prepare the bed for seed germination preventing soil erosion and preparing the ground for irrigation. Furthermore, tillage practices change soil water holding capacity, temperature, aeration, and the mixing of crop residues within the soil matrix. Today's real agricultural problems are resource depletion with declining production, decreased human resources, and rising prices and societal shifts due to different anthropogenic activities (tillage). These changes in the physical environment and the food supply of the organisms affect different groups of organisms in different ways. In addition, they are also affecting the environment health. Therefore, its management, including conservation tillage and other includes cover crop, organic residues, and direct sowing of rice seedling is necessary to mitigate the problems. The present review discusses the tillage systems effects on soil, plants, environment and their possible solutions.

Field experiments were conducted to determine the effects of herbivory, seed priming, and tillage practices on the growth response of Pisum sativum L. A factorial treatment design incorporated two levels of tillage treatment (moldboard and chisel plow), three levels of seed priming [Captan, PEG (polyethylene glycol) 8000, and Captan+PEG 8000], and four levels of herbivory by Sitona lineatus (L.) (caged controls, uncaged controls, 1 weevil/plant, and 8 weevils/plant). Pisum sativum stands at approximately 75% emergence were infested for 1 wk. Sitona lineatus infestations resulted in defoliation of approximately 5, 25, and 55% for the control, low, and high weevil densities, respectively. Conservation tillage led to increased surface residue but did not affect soil moisture, temperature, or compensatory growth response of P. sativum. Seed priming treatments, incorporating PEG, led to an undercompensatory growth response of P. sativum, as did high levels of S. lineatus defoliation. Improved seed priming methods that promote vigorous seedling growth may help minimize the impacts of S. lineatus and suboptimal soil conditions on P. sativum.

Effects of previous crop residues and tillage practices on Fusarium head blight (FHB) of wheat were examined. Fusarium head blight was monitored in plots of the FHB-susceptible spring wheat cultivar Norm following crops of corn, wheat, and soybeans in 1995, 1996, and 1997. Moldboard plow, chisel plow, and no-till treatments were imposed perpendicular to crop strips to establish a range of residue levels in each of the previous crop residues. Fusarium head blight incidence and severity were greatest when wheat followed corn and least when wheat followed soybeans. Incidence and severity were lower in moldboard plowed plots than in either chisel plowed or no-till plots, although differences among chisel plow and no-till treatments were not apparent. Yields of wheat were approximately 15% lower in plots where wheat followed corn or wheat than in wheat following soybeans and were 10% greater in moldboard plowed plots than in either chisel plowed or no-till treatments. The deoxynivalenol (DON) content of harvested grain was significantly correlated with FHB incidence and severity. The DON level in wheat following soybeans, averaged across tillage treatments, was 25% lower than in wheat following wheat and 50% of the level in wheat following corn. These findings suggest that changes in regional tillage practices, principally the move toward conservation tillage and reduced-till systems, contributed to the recent FHB epidemics in the Upper Midwest. Because differences in the type and quantity of crop residues in small plots affected disease development, it is likely that local sources of inoculum, such as those within a grower's field, contribute directly to the inoculum load and disease potential. The implication of these findings is that selection of cultural practices aimed to reduce inoculum-borne residues will assist in the control of FHB.

Conservation tillage practices are poplar, environmental friendly and economically feasible approaches to increase the productivity and resource-use efficiency of arid and semi-arid rainfed ecosystems. Rainfed field experiments were accomplished at IARI, Pusa, New Delhi in 2010-11 and 2011-12 to evaluate root: shoot growth, productivity, profitability and nutrient uptake in mustard under the various conservation tillage practices with preceding rainy- season crops; pearlmillet, clusterbean and greengram; and organic mulches, viz. no residues, crop residues and Leucaena twigs applied to both rainy- season crops and mustard grown with common recommended package of practices. Higher root length density (RLD), root surface area (RSA), root volume density (RVD), average root diameter (RD), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) were recorded under clusterbean–mustard and greengram–mustard systems over the pearlmillet- mustard system. Interaction between crop residues and preceding rainy-season crops on growth parameters exerted significant variations, while yield attributes showed the mixed responses. Mustard seed yield was significantly higher (+51%) in 2010-11 (1.80 t ha-1) than that of 2011-12 (1.19 t ha-1). Economic analysis exhibited the highest returns and net returns/ Rs invested after clusterbean with Leucaena twigs mulching. The nutrient uptake followed the same trend as that of seed and stalk yield. It was concluded that growing mustard after clusterbean with Leucaena twigs mulching was high-yielding and profitable cropping system under conservation tilled semi-arid rainfed ecosystem.

The vineyards of Ruwer-Mosel valley (Germany) cultivated on steep slopes showed a high spatial and temporal variability of hydrological dynamics. Forty two experiments were carried out using a Guelph permeameter in old and young vines to measure the infiltration rates, the hydraulic conductivity and the soil matrix flux potential. The essays were performed before (spring-summer) and after (autumn) the harvest with dry soil conditions and without soil tillage signals, and with humid soil conditions, signals of soil farming (wheel traffic and footprints) and a decrease of organic matter, respectively. In general, the results of the young vineyards were higher than the values of the old vineyards. Furthermore, all the rates increased after the harvest. For the young vineyards, the most elevated values were registered on the middle slope (398.5 mm h-1 infiltration rate, 89.2 mm h-1 hydraulic conductivity and 62.8 mm2 h-1 soil matrix flux potential). For its part, a decrease of the infiltration from the upper slope to the foot slope was observed (from 42.5 to 16.8 mm h-1). Hydraulic conductivity and soil matrix flux potential showed the same hydro-dynamic: from 13.2 to 5.4 mm h-1 and from 5.5 to 2.5 mm2 h-1, respectively. Finally, it was observed that the most correlated factor with these hydrological processes was the soil moisture content and the soil tillage practices.

Selection Of

The availability of various conservation tillage (CT) practices along with a variety of cover residues creates an opportunity for farm managers to create new systems for vegetable production. We established various tillage practices and cover crop residues for CT use to determine which systems would continue to deliver high vegetable productivity. Recommendations for using CT based only on a yield perspective would lead us to conclude that full season crops could be grown with some form of CT and respectable yields would be obtainable. Tomato (Lycopersicon esculentum Mill.) production with CT is successfully being practiced in North Carolina in both the mountain valleys and Piedmont region. Because of the cooler soil temperatures with cover residue, summer and especially fall harvested tomatoes produce the least risk in obtaining similar yields as plow/disc production. Our experiments with short season vegetable crops and CT have had mixed results. Cole crops (Brassica L.) grown with CT in early spring or late fall experience soil temperatures cool enough to delay growth compared to plow/disc management. Proper selection of a cover crop residue type and the amount of cover residue can increase yield. Growing short season vegetable crops with CT during the warmest season of the year will reduce the risk of delayed plant growth and thus, decrease the time to harvest.

Simultaneous Adoption

If adoption of herbicide-resistant seed and adoption of conservation-tillage practices are determined simultaneously, adoption of herbicide-resistant seed could indirectly reduce soil erosion and adoption of conservation-tillage practices could indirectly reduce residual herbicide use and increase farm profits. Our objective was to evaluate the relationship between these two technologies for Tennessee cotton production. Evidence from Bayes' theorem and a two-equation logit model suggested a simultaneous relationship. Mean elasticities for acres in herbicide-resistant seed with respect to the probability of adopting conservation-tillage practices and acres in conservation-tillage practices with respect to the probability of adopting herbicide-resistant seed were 1.74 and 0.24, respectively.
