IMPACT OF TILLAGE OPERATIONS ON SOIL PROPERTIES, PERFORMANCE OF WHEAT VERITIES AND ECONOMICS OF FARMERS UNDER SPATE IRRIGATION SYSTEM
Qudrat Ullah Khan
Abstract
Spate irrigation is a unique system of flood irrigation practiced in the piedmont plains of western Pakistan. Current research was carried out to evaluate the effect of wheat verities and tillage on soil characteristics, wheat attributes and economics of farmer. The experiment was laid out in randomized complete block design and split plot pattern. Wheat cultivars i.e. Pisabak - 15, Fateh Jhang and local landrace were placed in the main plots, while the tillage operation were kept in sub-plots asT1: Deep plough, T2: Cultivator before and after the flood, T3: Mulch tillage and T4: Zero tillage. The result of the study showed that the different verities showed non – significant effect on the soil properties, however the tillage practices significantly influenced the soil parameters including soil pH, bulk density, soil organic matter, nitrogen content. The agronomic parameters studied during the experiment showed significant effect of both the verities and tillage. Plant height, spike length, biological yield, grain yield, straw yield and harvest index was significantly changed. The grain protein content measured showed significantly higher total protein (13.61%) in the landrace as compared with the improved verities. The BCR calculated at the harvest of the experiment showed that 3.86 for the local landrace with deep plough and the least was observed 2.96 for the Fateh Jhang variety on zero tillage plots. It may be concluded from the above results that Pirsabak variety of wheat gave better result in term of yield. Landrace also showed a good response to tillage.
