“…The energy used by the sequence of operations of the CHDP system saved, on average, up to 64% of energy and NT saved up to 93% of energy, compared with the DDP. These findings are similar to the results obtained by other authors studying conservation tillage [46,47]. The amount of energy used is related to the volume of soil worked ( Table 7).…”

Energy used for tillage is an input with a high impact on the cost of crop production; it is desirable to till the soil using minimum energy. The objective of this study was to compare the specific energy expenditure, effect on soil bulk density, and forage yield of maize, by three tillage systems: Disk plow/Disk Harrow/planter (DDP), Chisel plow/Disk harrow/planter (CHDP) and No-Tillage (NT). Energy was measured for tillage operations in the summer season of 2013, 2016, and 2017. Bulk density in 2013 and 2016. Yield in 2013 and 2014. The variables of drawbar force (kN), working speed (m s−1), width (m), depth (m), fuel consumption (L ha−1), bulk density (g cm−3), and dry matter yield (Mg ha−1) were measured. Results showed that there were significant differences in the amount of energy used per ha; DDP used an average of 379.75 MJ, CHDP 135.01 MJ, and NT 26.43 MJ. The average energy applied to the soil mass for each system was 400 J kg−1 for DDP, 255.13 J kg−1 for CHDP, and for NT was 237.8 J kg−1. The overall energy efficiency was; 18.23% for DDP, 6.88% for CHDP, and 4.77% for N. The bulk density decreased significantly after three years for NT. There were no significant differences in dry matter yield. In the semiarid condition of Mexico, CHDP and NT are options for saving from 64% to 93% of energy, compared with DDP.

“…Usually this occurs because the harrow tends to penetrate more into the soil as the operations in the same area are repeated, what demands more effort from the tractor in the operation (Silva 2013). The demand for more tractor power also results in a higher fuel consumption (Yanai et al 1999, Hamzei & Seyyedi 2016, Theisen et al 2017. This fact was evident in this experimentation about the specific fuel demand, which increased with the repetition of the harvesting operation.…”

The presence of straw hinders the sowing of soybean cultivated in succession to rice, in areas irrigated by flooding. This study aimed to evaluate the combination of different configurations of a rice harvester and subsequent activities in the operational and energetic demand of rice straw management and in the soil surface roughness, in order to cultivate soybean in succession. Three independent experiments were conducted in a completely randomized design, as well as evaluated the fuel consumption, effective operating speed, working capacity and final surface roughness of the ground. The energy costs of harvesting rice do not increase when the automated harvester operates with a spreader to distribute the straw on the ground and to avoid the formation of furrows. The presence of rice plant residues in the field increases the skidding of the tractor when pulling the knife-roller, with a consequent reduction of the operating speed, but this does not affect the operational capacity and the fuel consumption. The increase in the number of light harrowings, from one to two operations, in areas worked with knife-roller or intermediate harrow, requires more time and fuel in the management of the soil and rice straw, but leaves the ground with less surface roughness. The management system with knife-roller operation and two light harrowings is the most appropriate method to prepare the soil for soybean cultivation after rice, because it provides the best combination of technical and energetic performance.

“…Typical species used in intercropping systems include legumes such as clover (Trifolium), vetch (Vicia), beans (Phaseolus vulgaris) and peas (Pisum sativum) and non-legumes such as barley (Hordeum vulgare), buckwheat (Fagopyrum esculentum), rye (Secale cereale), oat (Avena sativa), wheat (Triticum) and flax (Linum usitatissimum) (Chapagain and Riseman 2014;Hamzei and Seyyedi 2016). Intercropping with legumes can particularly enhance soil fertility by increasing soil nitrogen (N) through the N-fixing ability of rhizobacteria, thereby allowing more fixed-N to remain in the upper soil layers and be plant available (Hauggaard-Nielsen et al 2009a;Chapagain and Riseman 2014).…”

Intercrops and organic fertilizers can improve the productivity of cropping systems due to increased soil nutrient availability and plant nutrient use efficiency. A 2-year field experiment was conducted to determine the effects of different intercropping ratios and fertilizer types on nitrogen (N) and phosphorus (P) concentrations and yields of fenugreek and buckwheat at the research farm of Shahrekord University, Iran.
