The Determinants Of Agriculture Growth In China, 1978-89, Jiefei Qiu Jan 1997

The Determinants Of Agriculture Growth In China, 1978-89, Jiefei Qiu

Masters Theses

Agriculture growth in China during the first dozen years of the economic reform could be attributed to an increase in inputs, technological progress, and institutional innovation. This paper introduces a couple of measurements for technological change and institutional reform, which include the imported capital for advanced technology, the number of high school graduates for improved human capital and the size of the free market for price reform. The study examines the effects of education, foreign capital, and price reform in rural China using data for both agriculture and farming over the period of 1978-89. Descriptions are made regarding the changes …

Diagnosis Of Livestock Production In Three Communities (Tunshi San Javier, San Antonio And Maria Auxiliadora) Using The Chambo Irrigation System - Guano, Egresado ÁNgel Montalvo Silva

Theses and Dissertations

During 43 weeks three communities belonging to the Chambo-Guano irrigation system (María Auxiliadora, San Antonio, and Tunshi San Javier) were studied. Each family had 0.662 ± 0.149 producing cows, 0.115 ± 0.048 dry cows, 0.381 ± 0.095 heifers, 0.252 ± 0.068 young bulls, 0.158 ± 0.052 bulls, and 0.568 ± 0.096 calves. The age at first mounting (21.696 ± 9.28 months) showed that the cows enter reproduction late. Of the cows, 71.94 ± 5.26% were of household varieties. To feed them, alfalfa was used at 79.86 ± 4.5%, undergrowth 56.83 ± 5.62%, corn stalks 48.2 ± 6.02%, kikuyu 19.42 ± …

Study Of Livestock Production Levels In Three Communities Near The City Of Riobamba, Raul Rolando Nuñez Lopez

Theses and Dissertations

This study was done by administering household surveys to 50% of the families in the three communities. Families were selected through stratified random sampling. This allowed us to determine how much families are exploiting species that have a significant level of production as well as whether they use them for a commercial activity or subsistence. With regard to cows, 60.40 ± 4.72% of families use them. Each family has an average of 1.68 ± 0.21 cows. Productive cows make up 36.9% of the above percentage, which is a majority. The measured rate of production was 6.48 ± 0.25 L/cow/day. Overall, …
