sugar  is very important role  in  humanbeing feed.  for sugar beet  production in tropical area detemine  sowing and  harvesting date is very important . for this reason three sowing date (1 sep, 20 sep and 10 oct) and three harvesting date (15 apr, 15 may and 15 jun) in complete blouck design as factorial with three replication in two year in sarpol area condoucted. results  showed  that  the...

introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...

The results of recent trials for winter wheat (Triticum aestivum L.) have influenced farming practice in the UK by encouraging the use of lower seed rates. Spink et al. (2000) have demonstrated that, particularly if sown early, wheat can compensate for reduced plant populations by increased tiller production. Results from seed-rate trials are usually analysed separately for each environment or ...

emergence of crops is affected by environmental factors such as soil water, salinity and sowing and seed quality. the present study was conducted to evaluate the effect of seed aging (seed quality) on emergence of wheat under optimum (control) and stressful conditions including salinity (2 levels), drought (2 levels) and deep sowing depth (physical stress). seeds (cv. ‘zagros’) were kept at a h...

Wheat (729.8 million tons) is second to rice as the main human food crop (FAO, 201415). In India, wheat is cultivated extensively in North-Western and Central zones. The area, production and productivity of wheat in India and Haryana during 2014-15 is 31.46 mha, 86.53 mt, 2749 kg ha -1 and 2.60 mha, 10.35 mt, 3980 kg ha -1 , respectively (Anonymous, 2014-15). Late sowing of wheat is a major pro...

evaluation of weed population and their interference on lentil varieties at different sowing date was investigated in a field experiment in khorramabad during 2005-06 growing season. the experimental design was a randomized complete block in factorial arrangement with 4 replications. the experiment had 3 factors including: planting date at three levels (autumn, winter, and spring) weed interfer...
