Q. What is soybean milk?

Ans. Soybean milk is highly nutritious and preparation is very simple. Sometimes it is compared with cow milk. By the following process soybean milk is prepared:
 

  • Soak soybean seeds in water for 8-10 hours. 
  • Remove skin. 
  • Crush the seeds to get fine paste. 
  • Mix water (6-8 times) with the paste. 
  • Strain it properly. 
  • Soybean milk is prepared.

Q. What is the reason behind the typical smell of soybean pulse?

Ans. Soybean contains an enzyme called “lypoxidase”. It is the reason for that particular smell and it hinders soybean to be a popular pulse crop.

Q. Raw soybean is not easily digestible. Why? How can it be overcome?

Ans. Soybean contains an anti-tripsinogenic protein. Hence the enzyme trypsin in our stomach can’t act properly. So the raw soybean is not easily digestible.

It can be overcome by boiling the raw seeds at 1000 C for 10 minutes. By this the unwanted materials get inactivated.

Q. Oil seeds can be inoculated with bacteria for nitrogen fixation. How?

Ans. By using “poly ethylene glycol” oil seeds can be treated with bacteria as this chemical ruptures the root cell protoplasm after which inoculation can be done.

Q. If I treat soybean seeds with Rhizobium japonicum, how much amount of nitrogen will be added to soil?

Ans. If soybean seeds are treated with Rhizobium, it can fix atmospheric nitrogen about 30-50 kg/ha/year.

Q. What is bio-fertilizer?

Ans. It is a preparation containing latent strains of living organisms that helps in fixing nitrogen or solubilizing phosphorus or mobilizing other nutrients in soil.

Q. What are the merits of bio-fertilizers using in the state Sikkim?

Ans. There are so many merits of using bio-fertilizers in Sikkim. The state is going to be an organic state soon. Hence the use of chemical fertilizers will be restricted soon. But the plant nutrient should be supplied through organic means. The merits are as follows:
 

  • Bio-fertilizers help to improve the soil physical health like water holding capacity, aeration, etc. 
  • Supply a considerable amount of nutrient to the crop. For example soybean if treated with Rhhizobium, it will add nitrogen @ 50 kg/ha/year. 
  • The methods of bio-fertilizers application are easier. 
  • Environmental pollution will be lesser. 
  • Human health hazards will be lesser. 
  • Helpful insects will not be killed which in turn minimizes the cost of cultivation by killing harmful insects.
  • Cost of cultivation will be lesser.

Q. What are the demerits of bio-fertilizers?

Ans. There are some demerits of bio-fertilizers. These are as follows:

  • Less availability of suitable strains, 
  • Storage problem, 
  • Marketing difficulties,
  • Natural and environment constraints, 
  • Soils having less than 10 ppm phosphorus content in some areas that is required to activate the bacteria (PSM), 
  • lack of technological expertise in understanding bio-fertilizers, 
  • Unawareness about usefulness and advantages of bio-fertilizers among the farmers, and
  • Less publicity of bio-fertilizers.
