In India, the production of turmeric is not even half compared to its potential. To analyze the possibilities for higher production in turmeric, this study was conducted at the BCKV, Gayeshpur, West Bengal, during 2011 and 2012, to evaluate the effect of irrigation scheduling (0.6, 0.9, and 1.2 irrigation water (IW)/cumulative pan evaporation (CPE) and rainfed) in main plots and nutrient management [100% inorganic, 75% inorganic + 25% FYM (Farm yard manure), and 50% inorganic + 25% FYM + 25% vermicompost] in subplots on soil moisture depletion and productivity of turmeric. The highest value of fresh rhizome yield (23.90 kg ha^?1) and qualitative indices were obtained with irrigation schedule at 0.9 IW/CPE ratio water regimes and 50% inorganic + 25% FYM + 25% vermicompost. The correlation coefficients of water use and yield of turmeric were found at 0.943. The combination of 0.9 IW/CPE and 50% inorganic + 25% FYM + 25% vermicompost improved the overall performance of turmeric crop.  相似文献

In this study, we developed an in vitro model for studying sperm–oviduct binding in the buffalo. Oviduct explants were prepared by overnight culture of epithelial cells in TCM‐199 medium under 5% CO₂ at 38.5 °C. Cryopreserved spermatozoa from buffalo bulls (n = 4) were incubated with the oviduct explants, and the sperm–oviduct explants complex was stained with JC‐1. The effect of sperm concentration (2, 3 and 4 million), size of the oviduct explants (<0.2, 0.2–0.3, 0.3–0.4 and >0.4 mm²) and time of incubation (1 hr and 4 hr) on binding index (BI—number of sperm bound to unit area of explants) was studied. No significant difference was observed in the BI among <0.2, 0.2–0.3 and 0.3–0.4 mm² size of explants; however, the BI decreased significantly (p < .05) when the size of explants exceeded 0.4 mm². The BI decreased significantly (p < .05) when the sperm concentration was increased to 4 million, while the duration of incubation did not have any significant effect on the BI. The interaction of bulls with explants size, sperm concentration and incubation time was not significant. The developed assay has the potential to be used as an in vitro model for studying sperm–oviduct binding in the buffalo.  相似文献
