The impact and cost of synthetic fertilizers as well as their associated risks on the environmental safety was becoming unaffordable. To alleviate these problems, integrating this synthetic fertilizers with easily available and an environment friendly compound like bio-char is of very high significance towards meeting our goal of increasing agricultural production and ensuring food security. Th...

a factorial experiment based on a randomized complete block design with three replications was carried out in order to study the effects of tuber size, nitrogen fertilizer and harvest date on yield and yield components of potato. this experiment was conducted in a grower’s farm in uraki village located in chabahar city, in 2011. in this experiment, the treatments were two levels of tuber size (...

The bias against mangrove areas in siting fish farms prompted a comparison of the cost structure and yield performance in upland and mangrove locations. Tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that substantial revenue could be realized from both farms. While the upland farms yielded average gross reven...

Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize w...

This study aimed to investigate the potential of giant reed for biomethane production by examining the influence of harvest time and frequency on the Biochemical Methane Potential (BMP), the kinetics of biomethane accumulation in batch reactors and the expected methane yield per hectare. The crop was cut at five different times, regrowths from early cuts were harvested in autumn and BMP of each...

there are varying patterns for growing different varieties of branched or non-branched sesame. this experiment was conducted during a two-year period (2000-2001) to identify the optimal practice for cultivation of the uni-branched sesame in the safi-abad agricultural research center, khuzestan province. the statistical design was set up as strip-plot in a randomized complete block with four rep...
