Guava (Psidum guajava L.) is one of the most favorable fruit crops in India and considered to be a well-executed, nutritionally valuable profitable crop. Recently, guava has secured higher demand within global trade because its nutritional value processed products. It hardy, prolific bearer produces fairly remunerative mainly cultivated on large commercial scale. bears three bahar seasons, viz....
Groundwater seepage contributes to irrigation return flows and surface waters. Knowledge of phosphorus (P) concentrations and loads in percolation water that enters the vadose zone and groundwater is necessary to assess and manage water quality. We measured the P in water leached below the crop root zone in a furrow-irrigated Pormeuf silt loam. Vacuum operated percolation samplers were used to ...
the present study aimed to investigate the possible effects of focused highlighted error feedback on grammatical accuracy of writing among iranian intermediate efl learners. after selecting 52 homogenous participants from among 70 university students attending azad university of rasht and randomly dividing them into two intact groups of 26 students, the researcher exposed the participants of th...
To evaluate the effect of micro-nutrients spraying on some agronomic characteristics of the safflower (Carthamus tinctorius L. cv. Isfahan landrace), under different cropping systems, an experiment was carried out as split plot based on randomized complete block design with three replications in 2011. Experimental treatments were including: cropping systems (high, medium, low input and ecologic...
Using treated wastewater led to increasing crop yield, but it may causes heavy metals accumulations and also their toxicity in soil and plant. In order to investigate the effects of wastewater on yield, forage yield components, and heavy metals concentrations in stem and leaf of sorghum, an experiment was conducted in the agricultural Research Institute of Zabol University in 2006-2007, using a...
corn–soybean cropping systems predominate. The effect of these cropping systems on indicators of soil quality Understanding long-term management effects on soil properties is only partially understood. Soil organic C has been is necessary to determine the relative sustainability of cropping systems. Soil physical, chemical, and biological properties were measured shown to increase in monocultur...
The chemical control of weeds raises serious concerns about food safety and environmental quality, which have necessitated the need for non chemical weed management techniques such as intercropping. Intercropping can suppress weeds and reduce the use of herbicides in production systems. Therefore, the objective of this work was to evaluate the effects of intercropping of faba bean and maize, as...
Cropland products are of great importance in water and food security assessments, especially South Asia, which is home to nearly 2 billion people 230 million hectares net cropland area. In croplands account for about 90% all human use. extent, cropping intensity, crop watering methods, types important factors that have a bearing on the quantity, quality, location production. Currently, produced...
The black dot disease of potato is a fungal disease caused by Colletotrichum coccodes (syn. C. atramentarium) that produces accervuli on infected underground plant parts which appear as black dots. The disease appears at the flowering stage and develops up to the season end. The survey on black dot disease of potato in two successive years indicated that the infection percentage is 39.86 in Fer...
