Data on seeded and harvested areas, production, average price and total value of sales of potatoes in Canadian dollars. Geography: Mexico.

Abstract

Syngenta is committed to increasing crop productivity and to using limited resources such as land, water and inputs more efficiently. Since 2014, Syngenta has been measuring trends in agricultural input efficiency on a global network of real farms. The Good Growth Plan dataset shows aggregated productivity and resource efficiency indicators by harvest year. The data has been collected from more than 4,000 farms and covers more than 20 different crops in 46 countries. The data (except USA data and for Barley in UK, Germany, Poland, Czech Republic, France and Spain) was collected, consolidated and reported by Kynetec (previously Market Probe), an independent market research agency. It can be used as benchmarks for crop yield and input efficiency.

Sampling procedure

A. Sample design Farms are grouped in clusters, which represent a crop grown in an area with homogenous agro- ecological conditions and include comparable types of farms. The sample includes reference and benchmark farms. The reference farms were selected by Syngenta and the benchmark farms were randomly selected by Kynetec within the same cluster.

B. Sample size Sample sizes for each cluster are determined with the aim to measure statistically significant increases in crop efficiency over time. This is done by Kynetec based on target productivity increases and assumptions regarding the variability of farm metrics in each cluster. The smaller the expected increase, the larger the sample size needed to measure significant differences over time. Variability within clusters is assumed based on public research and expert opinion. In addition, growers are also grouped in clusters as a means of keeping variances under control, as well as distinguishing between growers in terms of crop size, region and technological level. A minimum sample size of 20 interviews per cluster is needed. The minimum number of reference farms is 5 of 20. The optimal number of reference farms is 10 of 20 (balanced sample).

C. Selection procedure The respondents were picked randomly using a “quota based random sampling” procedure. Growers were first randomly selected and then checked if they complied with the quotas for crops, region, farm size etc. To avoid clustering high number of interviews at one sampling point, interviewers were instructed to do a maximum of 5 interviews in one village.

BF Screened from Mexico were selected based on the following criterion: (a) Smallholder maize growers Lagunillas (Guanajuato) and Atecucario (Michoacán) and Cuyoaco (Puebla) Weed control
Low to mid tech corn growers

(a) Smallholder tomato growers Tlayacapan (Morelos) Low Tech (Open Field, Sell on The Farm, use old CP portfolios, from Subsistence to small trading)

Data processing:

Kynetec uses SPSS (Statistical Package for the Social Sciences) for data entry, cleaning, analysis, and reporting. After collection, the farm data is entered into a local database, reviewed, and quality-checked by the local Kynetec agency. In the case of missing values or inconsistencies, farmers are re-contacted. In some cases, grower data is verified with local experts (e.g. retailers) to ensure data accuracy and validity. After country-level cleaning, the farm-level data is submitted to the global Kynetec headquarters for processing. In the case of missing values or inconsistences, the local Kynetec office was re-contacted to clarify and solve issues.

Quality assurance Various consistency checks and internal controls are implemented throughout the entire data collection and reporting process in order to ensure unbiased, high quality data.

• Screening: Each grower is screened and selected by Kynetec based on cluster-specific criteria to ensure a comparable group of growers within each cluster. This helps keeping variability low.

• Evaluation of the questionnaire: The questionnaire aligns with the global objective of the project and is adapted to the local context (e.g. interviewers and growers should understand what is asked). Each year the questionnaire is evaluated based on several criteria, and updated where needed.

• Briefing of interviewers: Each year, local interviewers - familiar with the local context of farming -are thoroughly briefed to fully comprehend the questionnaire to obtain unbiased, accurate answers from respondents.

• Cross-validation of the answers: o Kynetec captures all growers' responses through a digital data-entry tool. Various logical and consistency checks are automated in this tool (e.g. total crop size in hectares cannot be larger than farm size) o Kynetec cross validates the answers of the growers in three different ways: 1. Within the grower (check if growers respond consistently during the interview) 2. Across years (check if growers respond consistently throughout the years) 3. Within cluster (compare a grower's responses with those of others in the group) o All the above mentioned inconsistencies are followed up by contacting the growers and asking them to verify their answers. The data is updated after verification. All updates are tracked.

• Check and discuss evolutions and patterns: Global evolutions are calculated, discussed and reviewed on a monthly basis jointly by Kynetec and Syngenta.

• Sensitivity analysis: sensitivity analysis is conducted to evaluate the global results in terms of outliers, retention rates and overall statistical robustness. The results of the sensitivity analysis are discussed jointly by Kynetec and Syngenta.

• It is recommended that users interested in using the administrative level 1 variable in the location dataset use this variable with care and crosscheck it with the postal code variable.

Data appraisal

Due to the above mentioned checks, irregularities in fertilizer usage data were discovered which had to be corrected:

For data collection wave 2014, respondents were asked to give a total estimate of the fertilizer NPK-rates that were applied in the fields. From 2015 onwards, the questionnaire was redesigned to be more precise and obtain data by individual fertilizer products. The new method of measuring fertilizer inputs leads to more accurate results, but also makes a year-on-year comparison difficult. After evaluating several solutions to this problems, 2014 fertilizer usage (NPK input) was re-estimated by calculating a weighted average of fertilizer usage in the following years.

(prepared R.A.(Tony) Fischer 14 August 2021) This dataset contains three data files that were obtained and/or constructed an analysis of 60 years’ yield progress with irrigated wheat yield in northwest Mexico: 1. Wheat harvested area and average yield each harvest year for the irrigated Cajeme District of Sonora State, Mexico, from 1960 to 2019 (file name = 1. Annual wheat average yield and harvest area 1960 to 2019, Yaqui Valley (Cajeme District) 2. Monthly average Tmax, Tmin, precipitation total and frost days from November 1959 to April 2019 (only for November to April each year, which corresponds to the irrigated wheat season) for a location at or near the centrally-located CIANO (now CENEB) agricultural research station of the Yaqui Valley. Monthly mean solar radiation (Rs) was added from November 1967 (unavailable beforehand) (file name = 2. Mean monthly wheat weather 1960 to 2019 Yaqui Valley). 3. Daily solar radiation (Rs), Tmax and Tmin from November 1967 to April 2019 (again only for November to April each year) (file name = 3. Daily wheat weather 1967 to 2019 Yaqui Valley).

Locating and acknowledging the exact original sources of these data is not easy, but is explained at the beginning of each file and within the files if the source varies. The wheat area and yield data is publicly available soon after harvest, having been collated by Cajeme District grain receival authority in Cd Obregon, who also regularly provide updated multiyear records of the finalized annual numbers. This District comprises the bulk of the irrigated Yaqui Valley and has been synonymous with the Yaqui Valley for outsiders. The weather data comes from the International Maize and Wheat Improvement Center (CIMMYT) headquarters, which has operated a weather station at CIANO/CEBEB experiment station, located centrally in the Yaqui Valley since 1968. However, for most numbers before 1968 the State Hydraulic Resources (CONAGUA in Cd Obregon), using data held by CIMMYT was used, and a few numbers after 2000 were obtained from the Hydraulic Resources in Cd Obregon and the Sonora State meteorological service (REMAS in Hermosillo). A large part of the daily Tmax and Tmin data (1968 to 1999), although originally from CIMMYT, was collated by Professor L.A. (Tony) Hunt of Guelph University, Canada, as was the daily and (monthly) Rs data from 1968 to 1983. From 1984 the NASA web site has continuous daily Rs data closely matching the Hunt numbers, so this source was used thereafter, while Hunt and Fisiologia data (adjusted to match NASA data) was used from 1968 to 1983. Tmax and Tmin data are also available on the NASA site but did not match CIMMYT data well and was never used. So the weather data has several sources, which increases the risk of error. Only the very strong relationship right across the 60 year period between totally independent variables yield and Tmin reassures us that the weather data is sound.

A follow-up study (and associated database) will disaggregate the causes of the spectacular progress recorded.
