Field experiments were conducted during 2010 to 2011 to study effect of mole drainage on root and physiological parameters of soybean crop in temporary waterlogged vertisols of Madhya Pradesh. Under a split plot designed experiment with 3 replications, the selected mole drain spacing includes 2, 4, 6 and 8 m with average mole drain depth of 0.4, 0.5 and 0.6 m from ground surface. Under various treatment combinations the root length, root nodules per plant, leaf area index, crop growth rate and economic of soybean crop were recorded for continuous two seasons. The highest yield was recorded under S1D1 followed by S1D2 in pooled data analysis for soybean crop.

The abrasive and erosive-corrosive properties of eutectic Al-Si (LM6) alloy were studied. Microstructural features of the alloy were altered by controlling the T6 heat treatment parameter, and their influence on hardness, strength and elongation, and response of the samples in erosion-corrosion and abrasion conditions were studied. Characteristics of the Al-Si alloy samples were compared with those of Al conventionally used in agricultural machineries. Fabrication of a typical component using the Al-Si alloy was also explored in order to understand the feasibility of using the alloy system for the envisaged applications. The study suggests the response of the samples in different conditions to be greatly influenced by parameters like chemical composition, microstructural features and applied load, traversal distance and test environment. The performance of even the as cast Al-Si alloy is far superior to that of the conventional Al samples, while the T6 heat treated Al-Si alloy shows improved performance. Accordingly, the as-cast as well as T6 heat treated Al-Si alloy has potential for applications in agriculture as a replacement for the conventionally used Al. © 2012 The Nonferrous Metals Society of China.
