In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

Despite the importance of sesame (Sesamum indicum L.) in the world, this crop has received least research attention in Pakistan. Therefore, a field experiment was carried out to evaluate the performance of tillage system under various irrigation intervals and phosphorus levels on oil contents, yield and yield attributes of Sesame. The experiment was conducted at New Developmental Farm of the Un...

In sorghum and mungbean – lentil cropping system, field experiments were conducted for three successive years to assess the effect of mung bean residue incorporation on sorghum and succeeding lentil productivity along with different doses of phosphorus (P; 0, 30, 60 kg ha−1) applied to these crops. The level of soil fertility was also tested with or without incorporation of mung bean residue. T...

Dynamics of cropland soil organic carbon (SOC) in response to different management practices and environmental conditions across North China Plain (NCP) were studied using a modeling approach. We identified the key variables driving SOC changes at a high spatial resolution (10 km × 10 km) and long time scale (90 years). The model used future climatic data from the FGOALS model based on four fut...

in order to study the effects of nitrogen and drought stress on yield, yield components and seed quality of corn (hybrid single cross 704) a field experiment was conducted at agricultural research station in islamabad gharb in 2009. experiment design was split plots based on randomized complete block design with three replications. main plots included full irrigation requirement, 80 percent and...

A field experiment was conducted to study the integrated weed management in groundnut (Arachis hypogaea L.) for consecutive three kharif seasons in 2010, 2011 and 2012 at Breeder Seed Production Farm of Orissa University of Agriculture and Technology, Bhubaneswar with 7 weed management treatments in four replications. Weed free check (two hand weeding at 20 and 40 DAS and manually uprooting of ...
