Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...

in order to study the effect of sowing dates and cultivation methods on yield and other characteristics of two cultivars of common bean (phaseolus vulgaris l.) an experiment based on split plot design was carried out with three replications in 2007 at khorramdarreh region of zanjan province. treatments consisted of three sowing dates (may 21, june 4&19), two cultivation methods (furrow and basi...

Our sowing date experiment took place in the Demonstration Garden of Institution of Plant Sciences, Centre for Agricultural Sciences of University of Debrecen, in 2012-2014. The paper contains data of test year 2014. Our purpose, besides several other examinations, was to observe how sowing date influences the leaf area index and the activity of photosynthesis of maize hybrids, and how those fa...

in order to study the yield and growth indices of spring safflower as double cropping, an experiment was carried out in 2007 at the research farm of faculty of agriculture, yasouj university, iran. the experiment was a factorial based on randomized complete block design with three replications. factors included of combination of four sowing dates (may 16, june1, june 16 and july 2) and four cul...

background & aim: saline lands can be utilized by planting native medicinal plants tolerant to salinity. the quantity and quality these plants are changed during various seasons in agriculture systems. thus, this study carried out under salinity stress in order to examine the effect of sowing in two seasons on growth characteristics and essential oil  components of ajowan (carum capticum l....

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

sowing and harvesting date are the most important agronomic factors that we should pay attention to proper date selection for sowing date in order to achieve good crop establishment and to harvest date in order to achieve the best time for crop quantities and qualities ripening. farmers intend to germinate sugar beet seed at minimum environmental temperature. sowing date affects crop canopy dev...
