Mild to prolonged stress increased rice tillering and source-to-sink nutrient translocation under SRI management

System of rice intensification (SRI) is a water-saving agro-technique being popularized in Southern Asia including India. A particular key practice in SRI, reduced water application (no continuous flooding), needs to be more farmer-friendly for its mass adoption under traditional and non-traditional cultivation. A field experiment was conducted maintaining different water regimes throughout the crop season (vegetative as well as reproductive stages) by scheduling irrigation applications at 1, 3, or 5 days after disappearance of ponded water (DADPW), using two different plant spacings and two different varieties. With an increase in the period of water stress, tiller production was increased significantly (P ≤ 0.05) and found to be maximum under prolonged stress, i.e., 5 days after disappearance of ponded water (5 DADPW). Increased tiller production did not result in yield increments, but yield-contributing parameters (panicle weight, grain weight per panicle, filled grain percentage, and test weight) were confirmed as critical determinants of yield. Plant nutrient (NPK) uptake was reduced under stress conditions, but the translocation of phosphorus and potassium from sources to sink was increased significantly in this study. Nutrient utilization efficiency was also enhanced under mild (3 DADPW) to prolonged (5 DADPW) water stress conditions. No significant reduction in yield was recorded under mild water stress, and this resulted in increased water productivity; however, significant yield loss was observed under prolonged water stress (5 DADPW).

Impact of yarn extension on packing density of ring spun yarn

The present paper deals with a detailed study on the effect of progressive yarn extension on diameter, overall packing fraction, radial packing fraction at different radial positions and partial packing fraction at different segments along the length of a fibre. An image processing based system to characterize and visualize the configuration of fibers in yarn in extended mode has been adopted. It has been observed that with the increase of yarn extension at different intervals, yarn diameter continuously decreases but at different yarn extension intervals, the percentage decrease value in the yarn diameter is different. But the packing density of yarn does not follow the exact trend of yarn diameter with the extension of yarn at different intervals. The yarn packing density initially increases at very high rate, then at very low rate and finally the packing density of yarn rather slightly decreases with the increase in yarn extension. The radial packing density of the yarn is not uniform across the cross-section of the yarn and it is not maximum near the yarn axis, rather it is maximum at some distance from the yarn axis. The location of maximum radial packing densities of yarn changes with the yarn extension. The partial packing density along the length of yarn is not uniform and the results are equally applicable for all level of yarn extension.
