Combined effect of tillage system, supplemental irrigation and genotype on bread wheat yield and water use in the dry Mediterranean region

Approaches that can help reduce future water shortages and increase food production in the Mediterranean region include the capture of more rainwater and better use of scarce irrigation water. The objective of this study is to evaluate the additive effect of combining zero tillage, supplemental irrigation and adapted varieties of bread wheat on yield and water use. For this purpose, a trial was conducted at the...

Supply response of wheat in Bangladesh: Cointegration and vector error correction analysis

Numerous past studies on wheat cultivation in Bangladesh is criticized for using the weaker Nerlovian Partial Adjustment models and also for analytical interpretation through Ordinary Least Square (OLS) creating spurious results for time series data. This problem can be avoided if Econometric technique of co-integration is used. It is for this the present paper estimates the supply response of wheat in Bangladesh by...

Macro-mineral contents in ten species at three phenological stages in Tehsil Takht-e-Nasrati, District Karak, Pakistan

Livestock rearing is a common practice by the locals in Tehsil Takht-e-Nasrati, and source of livelihood. Low productivity due to poor health of livestock is a major consideration in the study area. In order to know whether this low productivity and poor health might be due to poor quality of forage, ten forage species were analyzed for macro-mineral quantification at three phenological stages. The palatability of these...

Sensory analysis of banana blended shrikhand

Shrikhand is a popular Indian dessert prepared by fermentation of milk. It has a semi-soft consistency and is sweetish sour in taste. Fresh Curd (dahi) prepared was partially strained through a cloth to remove the whey and produce a solid mass called chakka. Chakka was finely mixed with sugar and flavouring agents, to give a sweetish-sour taste. Shrikhand was prepared from dahi with a constant level of sugar (40%) and...
