  How have the recent interest and large-scale agricultural investments in Africa impacted on smallholder farmers in the region?

  The impacts could be positive or negative. Can you share some verifiable examples or documentary references? Thanks

    I agree with that. Which is why USAID and other large donors are now focusing on Value Chain Addition.

    If the area receives more than 750 mm rainfall, irrigation source can be developed by proper rain water management techniques. Refer to my work in plateau areas of Odisha (India), Himalyan areasIf the area receives more than 750 mm rainfall, irrigation source can be developed by proper rain water management techniques. Refer to my work in plateau areas of Odisha (India), Himalyan areas (uttrakhand of India ) and Andaman islands of India. Once the water is available, the land could be put to very productive use either with plants like jATROPHA, or even pastures and fodder trees to support livestock rearing the activity which can provide livelihood to many.

The problem of feeding the hungry-poor is more complex than most realize. ZERI of UN has one approach that has elevated hungry peasants to self-sufficient, middle class, providing food for themselves and others.

  Why could Ca-EDTA show increased leaf injury on fruit plants when compared to Ca nitrate at the same level of calcium?

  I have sprayed these chemicals on sweet cherry during fruit development @ 50 g and 100 g calcium/100 lts water. However, ca-EDTA caused leaf injuries at both levels.

The mixture was then homogenised using a homogeniser at a speed of 13,500 rpm for 2 min. The homogenate was incubated at 85 ºC for 1 h to dissolve total protein. The samples were centrifuged at 3500 × g for 20 min to remove undissolved debris. Now For solubulising your sample, you dont need to use tris-buffer and Beta mercaptoethanol. Once u get the supernatant, then you need to determine the protein content of the supernatant by Buiret or Lowry method. After that you have to dissolve the known quantity of supernatant into the sample buffer. Then you can follow a general procedure for running a SDS PAGE gel. Good Luck
