Producers in the northeastern semiarid region of Brazil have been cultivating irrigated corn. The commercialized product comprises mainly green ears and silage. However, irrigation crops for dry grain has questioned regarding costs price competitiveness relation to same non-irrigated cultivated other regions. In recent years, use drip tapes fertigation spread among corn producers region. aim th...

The present paper is a humble attempt to test the allocative efficiency of the farmers in a traditional Orissan agriculture system in terms of resource-use and crop selection. While examining their allocative efficiency it is noted that the rational farmers are not necessarily efficient farmers. The farmers in the sample area are found to be rational in taking production decisions and efficient...

Agriculture in Assam plays an important role for livelihood of the people residing State. Widespread practice traditional farming techniques and correspondingly low usage modern farm inputs, levels growth productivity incomes sector, effects about 75 per cent state’s population directly or indirectly dependent on agriculture, while 69 workforce state is actually engaged agricultural activities....

The East Asian monsoon (EAM) and the El Niño Southern Oscillation (ENSO) determine climate variability over much of East Asia, affecting vulnerable grain markets and food security in China. In this study, we investigated the variability of climate and of agricultural production in China in association with the East Asian summer monsoon (EASM) and ENSO. Data from China showed that a strong EASM ...

Water tables are dropping by approximately one meter annually throughout the North China Plain mainly due to water withdrawals for irrigating winter wheat year after year. In order to examine whether the drawdown can be reduced we calculate the net water use for an 11 year field experiment from 2003 to 2013 where six irrigated crops (winter wheat, summer maize, cotton, peanuts, sweet potato, ry...

Thrips tabaci is a major pest of high-value vegetable crops and understanding its population genetics will advance our knowledge about its ecology and management. Mitochondrial cytochrome oxidase subunit I (COI) gene sequence was used as a molecular marker to analyze T. tabaci populations from onion and cabbage fields in New York. Eight COI haplotypes were identified in 565 T. tabaci individual...

Summer maize (Zea mays L.) is one of the dominant crops in the North China Plain (NCP). Its growth is greatly influenced by the spatial-temporal variation of climatic variables, especially solar radiation, temperature and rainfall. The WOFOST (version 7.1) model was applied to evaluate the impact of climatic variability on summer maize yields using historical meteorological data from 1961 to 20...

This research was conducted to study of the essential oil content, some morphological parameters, crop evapotranspiration (ETc) and crop coefficient (Kc) of Summer Savory (Satureja hortensis L.) in the west of Iran (Khorramabad region) in 2017. Weighing Lysimeters (25 cm diameter and 30 cm height) were used to measure important morphological parameters, t...
