Introduction

Peanut (Arachis hypogaea) is a perennial, oilseed cultivar of legume family. It is an oil plant in terms of nitrogen enrichment of both human food, animal feed and soil (Rui et al., 2017). The protein value of 25-36% in peanuts and the fact that the amino acids in these proteins are easily digestible (Launio et al., 2018) provide the improvement of snack quality. The seeds are rich in substances such as K, Ca, Mg, P, Fe and S, as well as vitamins (Sandefur et al., 2017).

The most important issue is the structure of the soil where climate and irrigation problems are not experienced in peanut cultivation. Soil cultivation is of great importance because it forms fruits in the soil. If the soil has a heavy clay structure, it is difficult for the seed growth in the soil and the detachment of the capsules from the soil becomes difficult that increase harvest losses. This also affects the yield of peanuts. In order to achieve success in the crops where field crops such as peanuts are grown, a good seed bed should be determined by determining the most suitable soil tillage method for seed sowing. Soil cultivation methods to be used vary according to soil structure, plant harvested before cultivation, plant to be cultivated and presence of existing mechanization. However, growing environmental awareness, economic production demands and in the end because of the necessity to go to savings in energy use, Pakistan and has begun to make radical changes in tillage (Kan et al., 2018).

Tillage system plays an important role in the sustainability of agricultural production. A reasonable tillage is an important representative of increasing agricultural production, avoiding soil problems, and inappropriate tillage cause water and environmental pollution and soil degradation. The effect of tillage on the sustainability of the production system depends on soil type, climate, crop and management factors (Kuhn et al., 2016). In traditional soil tillage method, field traffic is intense, soil erosion increases, soil physical properties deteriorate, soil organic carbon decreases and fuel consumption is high. Additional efforts are being made to ensure high activity in the use of water, nutrients and energy in tillage under the intensive production system (Fernando et al., 2018). In intensive agriculture production, input usage increases, cause environmental deterioration and the need for mechanization increases while, negatively affects the sustainability of agricultural production.

In agricultural production, emphasis has been placed on increasing productivity and production as the main objective. Besides these; improvement of product quality, reduction of production inputs, protection of natural resources, environmental factors, economic production and sustainable agriculture. Therefore, sustainable agriculture and conservation tillage are gaining increasing interest as they significantly reduce production costs compared to traditional tillage (Sessiz et al., 2008).

For these reasons, a management system that does not adversely affect or protect the quality of the environment should be developed (Kuhn et al., 2016). Most of the energy spent in agricultural production is used in soil cultivation applications. As with other enterprises, it is aimed to generate the most income with the least input in agricultural enterprises. However, energy input costs of traditional tillage methods and stubble burning costs are high, it shows that different tillage methods should be tried in growing crops (Bara and Gokdogan, 2016). Reduced and protective soil tillage methods decrease soil erosion problem, evaporation of moisture in the soil, fuel consumption is minimized (Banjara et al., 2017).

Therefore, the aim of this study was to investigate and evaluate most economical and suitable tillage method for main crop peanut and second crop peanut during growing seasons 2018 and 2019.

Materials and Methods

This research was conducted at greenhouse research station of Northeast Agriculture University, Harbin in order to evaluate the effects of different soil tillage systems on crop yield and tractor fuel consumption sown in greenhouse system. The comparative economic analysis was also performed to input and output costs determination and to suggest a most beneficial soil tillage system.

The soil physio-chemical properties were evaluated before sowing of each season’s crop as mentioned in Table 1. The soil samples were collected thrice from each treatment plot within soil depth 0-30 cm. An 8 cm diameter core sampler was used to collect soil samples. The collected soil samples were pulverized and sieved through a 2 mm mesh sieve before physio-chemical analysis. Soil physical parameters were measured at two soil depths 0-15 and 15-30 cm using undisturbed core soil samples (Mondal et al., 2019) before commencement of study 2018-19. According to the soil analysis results, the saturation of the trial area was 58%, lime content is 14.15% and soil was loamy clay. Soil total soluble salt content of saturation sludge extract electrical conductivity and pH values were measured in pH meter instrument (Schultz et al., 2017). Lime (CaCO3) contents were measured by Scheibler calimeter (Allison and Moodie, 1965). The recommended (120 kg/ha N, 30 kg/ha P and 33 kg/ha K) were applied to the field in the form of Urea fertilizer (46% N), diammonium phosphate (DAP, 18% N and 20% P) and potash (MOP, 50% K) (Yadava et al., 2012).

The experiment was conducted according to completely randomized design (CRD) with 3 replications of the main and second crop conditions (Figure 1). The total 3,035 m2 (0.75 acres) were selected for the experiment with three replications. Sowing was carried out with a combined pneumatic single grain sowing machine with planter plates suitable for peanut seed sowing in greenhouse. Peanuts were planted to be 60 cm between row and 20 cm above row. Main crop peanut was sown in the mid of April, 90 kg seed per hectare in the main crop sowing was set to the norm of pneumatic single grain seeding machine (Pandia et al., 2015). The second crop sowing was done after the first week of September. The applied soil tillage methods were Conventional tillage (T1), Zero tillage (T2), Minimum tillage (T3) and Deep tillage (T4). The rest of the field activities were applied same in all treatments fields.

Soil tillage systems were compared in terms of yield, fuel consumption and economic aspects. Yield was calculated as kg/ha by harvesting all the plants in the middle two rows of each parcel. Fuel consumption in each tillage system was measured using “Completion Method”. In the economic analysis, total expenses per unit area were determined by considering the rental costs of agricultural machinery used in tillage and sowing systems (Akbamia et al., 2013). The yields of the tillage systems and the average sales prices in the region were used in determining the total revenue (output) per unit area. The results of the study were subjected to multiple comparison (LSD) test with variance analysis.

Yield (kg/ha) variance analysis results of the main crop and second crop peanut obtained from trial applications and LSD multiple comparison test results were given in Table 2. When the variance analysis probability values are examined in Table 2, it is determined that the effect of year 2018 and two-year average (compound) tillage methods on the yield of peanut fruit were statistically significant at the level of 1% and the year 2019 was significant at the level of 5%. If the variance results of the second product peanut were examined; The effect of the 2nd year and two years average (compound) on the fruit yield of soil tillage methods was found to be statistically significant at the level of 1% and the first year was significant at the level of 5%.

The analysis of variance analysis results of the first year of the study in the main product peanut, the effect of soil tillage methods on fruit yield was found to be significant at the level of 1%, while the second year was found to be significant at the level of 5%. The highest peanut fruit yield values according to LSD multiple comparison test; The first year was obtained from the T1 method with 4881.1 kg/ha and the second year was obtained from the T2 method with 5762.1 kg/ha. The lowest fruit yields were obtained from T3 method in both years.

When the effect of soil tillage methods on peanut fruit yield values were examined in terms of % difference; fruit yield difference between the method with the highest fruit yield value and the method with the lowest fruit yield value is approximately; 6% in the first year and 25% in the second year. When the average (compound) variance analysis results of all years are examined; The effect of soil tillage methods on the yield of peanut fruit was found to be statistically significant at 1% level. It was determined that the highest fruit yield value was obtained from T1 method with 5298.0 kg/ha and the lowest fruit yield value was obtained from T3 method with 4429.0 kg/ha. The difference between the highest fruit yield value and the lowest fruit yield value was approximately 16%. According to the variance analysis results of the first year of the study, the effect of soil tillage methods on fruit yield was found to be significant at 5% level while the second year was found to be significant at 1% level.

The highest peanut fruit yield values according to LSD multiple comparison test; first year was obtained from T1 method with 3357.1 kg/ha, and from T2 method with 3476.2 kg/ha in the second year. The lowest fruit yields were obtained from T3 method in both years. When the effect of soil tillage methods on peanut fruit yield values were examined in terms of % difference; fruit yield difference between the method with the highest fruit yield value and the method with the lowest fruit yield value was approximately; 8% in the first year and 26% in the second year. When the results of the variance analysis made for the yield values, which were the average of two years; The effect of soil tillage methods on second peanut fruit yield was found to be statistically significant at 1% level. The maximum fruit yield value was collected from T2 method with 3416.6 kg/ha and the lowest fruit yield value was obtained from T3 method with 2833.3 kg/ha. The difference between the highest fruit yield value and the lowest fruit yield value was approximately 17%.

Fuel consumption

The results obtained for variance analysis for fuel consumptions in different tillage systems of main crop and second crop peanut with significance levels and LSD multiple comparison test was presented in Table 3. It was determined that the effect of soil tillage methods on fuel consumption in main and second crop peanuts parcels was statistically significant at 1% level considering the average years 2018 and 2019 and 2-years average.

The variance analysis probability values of the first and second years of the study in the main product peanut showed that the effect of tillage methods on fuel consumption was statistically significant at 1% level. According to LSD multiple comparison test; In the first year, it was obtained from T4 method with 65.89 l/ha and in the second year from T4 method with 59.33 l/ha. The lowest fuel consumption values were obtained from the T2 method in both years with 34.96 l/ha in the first year and 33.20 l/ha in the second year. When the average (compound) variance analysis probability value of all years is examined; The effect of soil tillage methods on main product peanut fuel consumption was statistically significant at 1% level. It was determined that the highest fuel consumption value was obtained from T4 method with 62.61 l/ha and the lowest fuel consumption value was obtained from T2 method with 34.08 l/ha.

As seen in Table 4, the highest product costs (input) during 2018 and 2019 were obtained from T4 method (1204.6 and 1309.0 $/ha) and the lowest product costs (input) were obtained from T2 method (1184.9 and 1292.9 $/ha). The highest income (output) were determined by T1 (2272.1 $/ha) and T2 (3039.9 $/ha) in 2018 and 2019, respectively, while the lowest income (output) by T3 method (2128.0 and 2261.0 $/ha). When the benefit-cost ratios were examined, the highest ratios (1.89 and 2.35) were obtained from T1 and T2 tillage systems during 2018 and 2019, respectively, while the lowest ratio were obtained from T3 method (1.79 and 1.74). These results could be correlated with Bantilan et al. (2014), who observed grain yield in traditional chickpea was 850 kg/ha, production cost per unit area was 200.5 $/ha, production cost corresponding to chickpea weight is 0.24 $/kg and demanded product price is 0.28 $/kg. Of the total production cost of chickpea, 21.4 $/ha was from tillage and sowing, 5.3 $/ha is from maintenance operations, 44.5 $/ha is from harvesting, 87.59 $/ha is from various inputs and 41.68 $/ha is they have resulted from common expenses. In this study, peanut and wheat + II. It is aimed to compare different soil tillage methods in the product peanut.

In Table 5, in the economic analysis of different tillage methods in the second crop peanut, the total input varied between (763.8-776.2 $/ha) and (832.5-843.2 $/ha), while the output total ranged between (928.56-1007.13 $/ha) and (874.27-1181.90 $/ha) in 2018 and 2019 seasons, respectively. The highest benefit-cost ratios were 1.30 with T1 and T2 soil tillage methods in 2018 and 1.42 with T2 in 2019 season.

In Table 7, as a result of economic analysis of different soil tillage methods in wheat + second crop peanut, the values of input and output amounts are expressed in monetary terms. The highest input was obtained from deep tillage system (T4) with 1461.2 and 1588.7 $/ha, while the lowest input was determined from zero tillage system (T2) with 1441.9 and 1572.0 $/ha in 2018 and 2019 growing seasons, respectively. The highest benefit-cost ratios were obtained from conventional tillage (T1) and zero tillage (T2) with 1.47 in 2018, while zero tillage (T2) showed maximum benefit-cost ratio (1.55) in 2019 crop season. The economic analysis of different soil tillage methods in wheat + second crop peanut values of input and output amounts of 2019 season are expressed in monetary terms. The results are in line with Gudadhe et al., (2016), who determined that the highest energy benefit-cost ratio of chickpea was obtained from zero soil tillage method with 2. This was followed by the reduced tillage method with 1.81, direct sowing + herbicide method with 0.87 and traditional soil tillage with 0.205, respectively.
