Evaluation of tillage systems on agronomical aspects in roselle-green gram intercropping using Replacement method
Author(s):
Abstract:
A field experiment was conducted at research station of Zabol university in 2012. The experiment carried out as split plot on basis of a randomized complete block design with three replications. The main and sub factors included tillage systems (No, reduced, and Conventional tillage) and planting ratios of intercropping (pure culture of roselle, pure culture of green gram, 25% roselle 75% green gram, 50% roselle 50% green gram and 75% roselle 25% green gram), respectively. For roselle, the results showed that the effects of tillage systems and planting ratio was significant on plant height, diameter of stem, lateral branch, number of fruit and sepal yield. For green gram the results showed that the effects of tillage systems and planting ratio was significant on plant height, number of pods in plant, number of seed in pod and economical yield. Tillage systems had not significant different on land equivalent ratio but comparison of means showed that the maximum and minimum of LER was obtained in conventional and reduce tillage, respectively. The maximum of LER was obtained at 75% green gram plus 25% roselle (1.36). In general, more useful intercropping confirmed than a pure culture of roselle and green gram.
