Agronomical and yield responses of forage soybean to plant density, fertilization rate and furrowing
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 5
Abstract
In order to find essential information for efficiency management of soybean fields is being advocated as a new strategy and approach to redress farm, however biomass harvesting has been recommended because of disorder on sheathing. A field experiment was undertaken at educational and researchable field of Gorgan university-Iran during 2013 to determine whether soybean has yielded and economic advantage at this stage as replacement strategy. This research was laid out in a randomized complete block design arranged in a split plot factorial with three replications. The manure consumption are consisting of 3 levels, 100, 200 and 300 kg ha-1 urea (46%), plan density at 3 levels included; 100000, 150000, 200000 plants ha-1and land aeration at 2 levels; furrowed between rows and un furrowed. Fix distance of soybean is 50 cm and distance; those totally were including 54 plots. The results showed that all studied characters were significant at 5% level. Mean comparison of fresh yield, internodes distance, number of nodes, number of empty pod and height to node of soybean at deferent plant density demonstrated, with increasing number of plants to 200000 plants per hectare, consumption of 300 kg ha-1 urea and furrowing between soybean rows the mention parameters increased. Also double and triple interaction of plant density × fertilizer consumption ×plowing showed fresh yield, internodes distance, number of node, number of empty pod, number of pod filling and height to node were highest with increasing plant density, urea and furrowing between soybean rows. The quantitative increase were 26120 kg ha-1, 4.83 cm, 20.33, 73, 45.6 and 4.16 respectively. Overall findings demonstrated using fertilizer and furrowing between forage soybeans rows may allow for more efficient bushes to capture of urea, followed aeration caused to greater agronomical parameters and performance yields.
