Effect of conservation tillage and remains under the influence of drip irrigation on watermelon yield in the Bardsir Region
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 13
Abstract
Cultivation two products in one year, due to the limited opportunities to prepare the seed bed for the second crop after wheat harvest and loss of soil organic matter due to harvesting or burning of crop residues before and continuous cultures is one of the agriculture of problems in the city Bardsir. However, due to the use of machines such as conventional moldboard plow and disk tillage destruction of soil structure in this way, use of alternative tillage can be one of the best options to achieve sustainable agriculture. In order to test split plot in a randomized complete block design with triplicate in a sandy loam soil land with villages Dashtkar was implemented in 1391. Management and conservation tillage remains the main treatment includes: 1. Conventional tillage (moldboard plow + disk), 2. Strip tillage (heavy cultivator Cultivation online + disk 2 times) 3. minimum tillage (plow ink) 4. No tillage (direct sowing of seeds) and 4 leftover amount as subplots include: 90 percent, 60 percent, 30 percent and remains, were evaluated. Based on the results of this study, Simple effect of tillage treatments and the remains were significant at 1% level. So that the treatment reduced tillage 24,200 kg maximum performance and no tillage treatments assign minimal performance with 11,433 kg. Between conventional tillage and minimum tillage treatment were not significant differences. After analysis of variance results indicated that the minimum tillage treatments with 60% of the traffic remains lower agricultural machinery, maintain soil structure, crop yield and soil moisture had the best performance compared to other treatments.
