This paper demonstrates the potential of using Web search volumes for generating crop specific planting and harvesting dates in the USA integrating climatic, social and technological factors affecting crop calendars. Using Google Insights for Search, clear peaks in volume occur at times of planting and harvest at the national level, which were used to derive corn specific planting and harvestin...

to study the effects of sowing dates, irrigation intervals and different cultivars on sugar beet root rot disease management and its quality and quantity yields, an experiment was conducted in a split- factorial based on randomized complete block design with four replications in the field of sugar factory jame. two irrigation intervals: eight days and 16 days were allocated in main plots, and d...

This study was carried out to investigate the yield response of 2 soybean (Glycine max (L.) Merrill) cultivars to different planting dates and plant populations and to examine the relationships of seed yield with leaf area index (LAI) and total dry matter (TDM) during the vegetative and reproductive periods for planting dates, plant populations, and cultivars. Two soybean cultivars, A3127 (earl...

Corn (&a mays L.) growth has been shown to be affected by planting date and amount of residue on the soil surface. The objective of this study was to determine if the adverse effects of cool soil temperatures on early seedling growth often associated with surface residues can be overcome by planting at later dates. Corn was planted at several planting dates (late April through early June) into ...

planting at the right time and supplemental irrigation are considered as the effective management practices in increasing rain productivity and rainfed lentil yield and have been discussed in several studies. in this study, the suitable planting date and supplemental irrigation time for lentil in qazvin weather conditions were examined in a computerized model. in this model, soil water content ...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...
