Analysis of power requirement of a small-sized tracked-tractor during agricultural field operations

A low-powered and high-efficiency electric tracked-tractor would be a suitable option for aged and female farmers to accomplish agricultural field operations such as grass mowing, land leveling, and chemical spraying. The purpose of the study was to analyze the power requirement of a small-sized tracked-tractor during agricultural field operations. A lawnmower and a rear sprayer-trailer were attached to the tractor base, and the average power requirement was measured. The forward speed was considered during the field experiment up to 6 km/h for four different operating stages. The torque data were obtained for unloaded and loaded conditions through a wireless data logger, and a GPS receiver was used to measure the working speed of the tractor. A data acquisition module was used to acquire the sensor signals. The average power requirements for the empty platform with the driver, a lawnmower, a sprayer-trailer (150-L payload), and a lawnmower and 150-L payload trailer were 0.93, 1.27, 1.45, and 1.70 kW, respectively. The result showed the lowest power was required for operating only the tractor, and it was about 51.15% of the motor rated power, where the maximum power consumed approximately 85% of the total rated power to operate both of the lawnmower and sprayer-trailer. The average power requirements of the tracked tractor varied due to the different payloads and operating stages. The experimental results presented in this study would provide guidelines to improve and commercialize the prototype of the small-scaled tracked-tractor for practical use on the agricultural fields.

Soil Organic Carbon and System Environmental Footprint in Sugarcane-Based Cropping Systems Are Improved by Precision Land Leveling

A six-year experiment (2009 to 2015) was conducted on sugarcane-based cropping systems in farmers’ fields to examine the effects of precision land leveling (PLL) compared to traditional land leveling (TLL) in terms of soil organic carbon (SOC), greenhouse gas emissions, irrigation water requirements, and system productivity and profitability. Twelve treatments compared different sugarcane sowing regimes and crops in rotation under both PLL and TLL. Spring-sown sugarcane grown in rotation with rice, potato, and wheat under PLL had the highest production (89.7 kg ha−1 day−1) and required 142 cm irrigation water, which was 35.1% less water than a commonly practiced cropping system with late-sown sugarcane grown in rotation with rice and wheat only under TLL). Cropping systems established under PLL had higher land use efficiency (ranging between 64.9 and 86.2%), higher energy productivity (90.7 to 198.6 GJ ha−1), and lower greenhouse gas emissions (5249.33 to 944.19 kg CO2 eq ha−1 yr−1) than those under TLL. As well, treatments under PLL had increased levels of SOC, particularly in the upper soil layers, relative to SOC in treatments under TLL. Combining PLL with diversification of crops in sugarcane cropping systems has the potential to sustainably increase farmers’ land productivity and profitability while improving soil health and reducing irrigation requirements. These benefits are likely to have applications in other sugarcane-based cropping systems in similar agro-ecologies.

Adoption of climate-smart agriculture technology in drought-prone area of India – implications on farmers' livelihoods

PurposeLaser land leveling (LLL) is a climate-smart technology that improves water use efficiency and reduces risk in crop cultivation due to weather variability. Hence, this technology is useful for cultivating water-intensive crops in a sustainable way. Given this background, the state government of Karnataka initiated to promote LLL in drought-prone districts and selected Raichur district for implementation. Moreover, farmers in this district had observed drought situation during monsoon paddy growing season in 2018. Therefore, this study attempts to investigate the importance of LLL technology for paddy cultivation under drought conditions.Design/methodology/approachA primary survey with 604 farmer households had been conducted in Raichur in 2018. Among them, 50% are adopters of LLL who have been selected purposively and rest 50% are non-adopters who have grown paddy in the adjacent or nearest plot of the laser-leveled plot. The adoption and causal impact of LLL has been estimated using propensity score matching, coarsened exact matching and endogenous switching regression methods.FindingsThe result reveals a positive and significant impact of LLL on paddy yield and net returns to the farmers. The results indicate an increment of 12 and 16% in rice yield and net income, respectively, for LLL adopters in comparison to the non-adopters of LLL.Research limitations/implicationsThe major limitation of the study is that it does not adopt the method of experimental study due to certain limitations; hence, the authors employed a quasi-experimental method to look at the possible impact of adoption of LL.Originality/valueThere have been various agronomic studies focusing on the ex-ante assessment of the LLL. This study is an ex-post assessment of the technology on the crop yield and farmers' income in a dry semi-arid region of India, which, according to the authors, is the first in this approach.

"Quantification of Incremental Benefits and Change in Input Use Pattern under Laser Land Levelling in comparison with Conventional Land Levelling in Haryana"

The investigation aimed to find monetary benefits of Laser Land Levelling (LLL) compared to conventional land leveling (CLL) in Karnal and Sirsa district of Haryana. These two districts were selected purposively because these have the highest area under paddy-wheat and cotton-wheat cropping patterns, respectively. The equation of Aryal et al. (2014) was explicitly used to estimate incremental benefits from laser land leveling. Also, input use pattern of machine labor, seed, plant protection chemicals, human labor, yield, and irrigation was considered. In the paddy-wheat cropping pattern of Karnal district, the annual net benefits of using laser land levelling were estimated to be ` 11450.81. In contrast, per LLL operation, net benefits were estimated to be ` 34352. Similarly, on the same lines in the cotton-wheat cropping pattern of Sirsa district, the annual net benefits of LLL were estimated to be ` 7212.61. In contrast,per LLL operation, net benefits were estimated to be ` 28850. As far as the input use pattern is concerned, the study showed that machine labour and yield increased under LLL while in both districts. In contrast, all other inputs i.e., seed, fertilizer, human labor, plant protection, chemicals, irrigation, were reduced, showing resource conservation potential of LLL. Hence, the study recommended adopting this resource conservation technology and tapping its potential benefits so that farmers may get benefitted from this ultimate technology

Carbon Dynamics in Climate Smart Agriculture Precision Land Leveling Practices on Topsoil Microbial Community Changes and Soil Organic Carbon in Cereal Based Cropping Systems of Sub-Tropical India: A Review

The role of soil microorganisms in the biogeochemical process and nutrient cycling of soil is critical and is colossally impacted by agronomic management practices. In order to establish climate-smart precision land leveling practices in cereal based cropping systems, comprehension of the land bacterial local area and supplement nutrient dynamics under differentiating management practices is of most extreme significance.
