Research on corn production efficiency and influencing factors of typical farms: Based on data from 12 corn-producing countries from 2012 to 2019

Abstract

Globally, corn is characterised by high production and high export concentrations, yet the world is experiencing an unprecedented, huge change in this regard. Ensuring the global supply of corn, and thereby the energy and food security of nations has become particularly important. To understand the importance of corn production as an influencing mechanism of global food supplies, the present study researched the corn production of typical farms in major corn-producing and importing countries around the world. I selected the corn input and output data of 18 typical farms in 12 countries from 2012 to 2019, used the data envelopment analysis (DEA) model to calculate the technical efficiency of corn production, and built a tobit model to explore the impact of farming methods, input elements, supporting services, and other factors on efficiency. The study established that the average comprehensive technical efficiency of corn production on a typical farm was 0.863, and the average loss was 13.7%. In addition, it concluded that intensive tillage and conservation tillage have high technical efficiency. It also demonstrated that the proportion of mechanical labour and technical efficiency is in a ‘U’-shaped relationship, among others.

Fungal diversity and mycotoxins detected in maize stored in silo‐bags: a review

“…1). Argentina, Brazil, USA and Ukraine are the main maize exporting countries of the world, 43 and it is essential for them to have knowledge of the fungi and toxins commonly found in maize stored in silo bags. The average total fungal content in maize grains stored in silo‐bags was 3.13 ± 0.53 × 10 10 cfu kg −1 maize.…”

Agricultural Technical Efficiency of Smallholder Farmers in Tanzania: A Stochastic Frontier Approach

“…This part presents various technical efficient levels across countries on different crops and then TE in Tanzania is presented as well. According to a study conducted by Wang & Hu, (2021) in 12 countries (Argentina, Brazil, and Uruguay (South America), Russia, France, Ukraine, Bulgaria, Poland, Czech Republic, and Hungary (Europe), as well as the US (North America) and South Africa) on corn production, the average technical efficiency revealed was 86.3% which imply that these countries are efficient in producing corn and have room to increase their crop outputs by 13.7% with the same inputs. A cross-sectional study conducted in Kenya focusing on Tomato production efficiency by Mwangi et al, (2020), revealed that Kenya is inefficient in producing tomatoes whereby the technical efficiency (TE) level stood at 39.55%.…”

Economic Analysis of Corn Plantation Factors Using Geographic Information System Through Location Quotient and Shift Share Method in East Java Province

“…Corn is one of the most widely-planted crops in the world. It is grown in more than 170 regions globally [1]. This sector provides food for most of its population, provides employment for almost all of the existing workforce, produces raw materials, raw materials or aids for the industry and becomes the largest source of foreign exchange earnings [2].…”
