Rainfed environments are characterised by unpredictable and highly variable seasonal rainfall and hence highly variable yields. Water use efficiency (WUE, yield per unit of water use) is commonly used for agricultural production with limited water resources. Expertise working towards the water resources need to address the multitudinous aspects in which cropping systems and amounts, timing and ...

Estimations of crop area were made based on the temporal profiles of the Enhanced Vegetation Index (EVI) obtained from moderate resolution imaging spectroradiometer (MODIS) images. Evaluation of the ability of the MODIS crop detection algorithm (MCDA) to estimate soybean crop areas was performed for fields in the Mato Grosso state, Brazil. Using the MCDA approach, soybean crop area estimations ...

170 Mango is one of the most important and widely cultivated tropical fruits of the world. In India, it is grown in an area of 23.78 lakh hectares with an annual production of 161.98 lakh tones (Indian Horticulture Database-2012). This contributes to 37.8 per cent of total area and 18.6 per cent of total production of fruit crops in India. The plant start bearing 4 to 5 years after planting and...

A field study was initiated in 1992 to investigate the long-term impacts of beef feedlot manure application (composted and uncomposted) on nutrient accumulation and movement in soil, corn silage yield, and nutrient uptake. Two application strategies were compared: providing the annual crop nitrogen (N) requirement (N-based rate) or crop phosphorus (P) removal (P-based rate), as well as a compar...

I the past, agricultural markets have been well integrated. Markets for different energy commodities, especially liquid energy products, also have been tightly linked. But agricultural markets and energy markets have not been closely correlated. Table 1 contains partial correlation coefficients between pairwise prices (both levels and first differences) of corn, soybeans, crude oil, gasoline, a...

Soybean is one of the main sources of foreign exchange credits for Brazil in the agricultural sector. There is increasing interest in growing this leguminous crop, especially in the southern region of Minas Gerais, due to its importance as an alternative for crop rotation with maize. In this respect, the study of the adaptability of new cultivars to the region is indispensable so as to obtain h...

After three to four decades of substantial inlittle evidence of a trend, it is considered to crease, yields per acre of major U.S. crops aphave plateaued. The second objective is to pear to have tapered off. The average annual investigate whether a crop yield series, if rate of growth in crop yields' decreased trendless, is random or oscillatory and, if nonmarkedly from 2.7 percent for the 1950...
