| Popis: | Soil water variations are due to topographic characteristics of soil and land uses on the sloppy lands. The objective of this study was to monitor the soil water variation in relation to three cropping patterns and three different terraces at Khairimurat area during 2007-08. Three cropping patterns were Wheat (Triticum asetivum L.) – Millet (Pennisetum glaucum) – Fallow, Wheat – Millet – Lentil (Lens caulinaris) and Wheat – Fallow and terraces were low height terrace (5 feet high from the leveled field), medium height terrace (3 feet high from the low terrace) and high height terrace (2.5 feet high from medium terrace). Soil water measurements were performed monthly from above mentioned cropping patterns under different terraces and measured by adopting gravimetric method at six depths of the soil profile at an interval of 15 cm (0-15, 15-30, 30-45, 45-60, 60-75 and 75-90 cm). The soil water was available maximum on high height and low height terraces but it was observed minimum in medium terrace. Thus, the low delta crops on medium terrace should be planted instead of growing high delta crops. Actually, the medium terrace contains relatively low clay contents which resulted low retention of soil water. The soil water contents within all terraces down to the depth increased linearly. The rainfall distribution was almost same on the study site during the rainy season. However, the temperature variation trend at all the locations was season dependent. This study provides an idea for crop management under arid environment and to introduce the suitable crop in their cropping pattern. Hence, the high delta crop in the existing cropping patterns could be replaced by the new cropping patterns depending upon the findings of soil water availability. |
