Abstract

The population of Pakistan is increasing at an alarming rate, leading to a high demand for more food and fiber production. To address this demand, effective land and water management is required, emphasizing improvement in irrigation and fertilizer use efficiencies of conventional irrigation methods. This study therefore aimed to determine the impact of various tractor wheel compaction and fertilizer placement at ridge bed irrigation method on different soil textures during 2017-18 and 2018-19 at Sindh Agriculture University, Tandojam, Pakistan. The several levels of compaction observed were, without compaction (T1), three-round tractor wheel compactions (T2), and six-round wheel compactions (T3), while the soil textures were clay loam (CL), silty clay loam (SCL), and silty loam (SL). The field trials were conducted in spilt plot in a randomized complete block design (RCBD) with three replications. The results showed that different treatments significantly affected plant growth, yield of wheat, water productivity, and net returns with ridge bed furrow irrigation method. Further, results showed that all parameters significantly increased with increasing soil compaction levels in all soil textures. Based on the results, it was concluded that T3 integrated with fertilizer application at the top of the ridge bed was the most promising method for enhancing the water and fertilizer use efficiency for the wheat crop.

Abstract

Water and minerals are the key resources for citrus production. However, their excessive use can hinder plant growth and lead to economic losses. This study aimed to evaluate the effects of different polymers on soil properties, lemon plant growth, irrigation intervals, and water saving. The treatments were control (T0), water-pad polymer laid at the bottom of the plant pit (T1), polymer in powder form at 3 g/kg of soil (T2), and polymer in crystal form at 3 g/kg of soil (T3). To avoid seepage losses, a plastic polyethylene sheet was placed along each side of the pit, and one-year-old lemon plants were transplanted in each pit. The results show that soil physical and chemical properties significantly improved in all treatments when compared with the control treatment. The improved hydro-physical characteristics increased the irrigation interval and reduced the number of irrigations by 50%. The accumulation of soil minerals (Ca and Mg) and soil cations (K and Na) was significantly increased than control. Water saving of 39% and substantial improvement in plant growth were observed in all polymer treatments. The water and mineral saving and significant improvement in plant growth show the hydrogel as a resilient soil amendment for plant growth and economic benefits.
