A field experiment was conducted to investigate the effect of soil application of zinc fertilizer on yield and yield components of wheat (Triticum aestivum L. cv. Pak-81) grown on calcareous soil in Pakistan. The levels of zinc sulphate were 0 (control), 5, 10, 15, 20, 25 and 30 kg ha and the zinc sulphate was combine-drilled at the time of sowing. Zinc sulphate increased the Leaf Area Index, t...
We investigate the determinants of aggregate commodity returns and establish the following findings. (1) Common predictors of bond and stock returns, such as the short rate and the yield spread, also predict commodity returns. A high yield spread predicts low commodity returns, consistent with commodities being a hedge for market fluctuations. (2) Even controlling for these common predictors, a...
To increase grain yield, nitrogen use efficiency (NUE) and nitrogen apparent recovery fraction (NARF) in wheat (Triticum aestivum L.), an experiment was carried out in Karaj Soil and Water Research Station farm for two consecutive growing seasons in 2004-05 and 2005-06. The experimental design was RCBD with 6 treatments (T1= Control T2= 150 kg ha-1 of N as urea in 3-split applications T3= 1/3 N...
This paper examines the effect of elective surgery receipt on paid and unpaid labor supply amongst older adults. I find that osteoarthritic patients receiving elective hip or knee replacements in hospital referral regions with high rates of elective procedure use, where the marginal surgery is believed to be more discretionary, increase participation in paid work and volunteering after surgery....
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
We establish several new findings on the relation between open interest in commodity markets and asset returns. High commodity market activity, as measured by high open-interest growth, predicts high commodity returns and low bond returns. Openinterest growth is a more powerful and robust predictor of commodity returns than other known predictors such as the short rate, the yield spread, the ba...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
This study evaluated the symbiotic effectiveness and economic evaluation of Rhizobium inoculants with the objective of recommending the most effective inoculant strain for soybean and cowpea production in Northern Ghana. Field experiments were established in three locations using randomized complete block design with five blocks. A total of four treatments (Legumefix, Biofix, 100 kg N ha-1 and ...
“Given the high land values in central business sections of our leading cities, the skyscraper is not only the most efficient, but the only economic utilization of certain strategic plots. An exhaustive investigation... has conclusively demonstrated that the factors making for diminishing returns in the intensive development of such plots are more than offset by the factors making for increasin...
