Padi 2

“Pusu (a local padi variety) needed low management, but it produced low quality rice. Whereas Laila is of higher quality and needs good management to produce the high yields desired,” said Hjh Normah

Last time i went to Wasan, i was visiting the Lt Col ‘s farm. Col told me Koseka was given 99 hectares.. ahaha… how many football fields can you put in there… The farmers are using this Padi system check:  nutrient reading technique called “minus one element technique”. this farming tech is taught in Wasan school.Havent research much on these yet so not sure how this tech actually help the farmers. http://www.bt.com.bn/news-national/2010/08/11/right-school-rice-farmers

From my previous post, i had mentioned that the good harvest time should yield up to 11 tonnes per hectare. when harvest is poor will yield at least 3 tonnes. The reason for the reduction in harvest is due to fungal infection in Padi. (link).

From my experience of planting a few 4th or 5th generation padi stalk just for fun. I noticed that the padi quality that i had planted were not as good at those in wasan.. and somewhat “weak”. most of the padi plants had red dots on the junctions between the branches and the seeds. The red dot will totally prevent any growth and the seeds would just be empty husk.. This is probably due to the genes dilution of the original hybrid “Padi Laila”. The original strength of the hybrid padi plant is gone.

In Wasan, the farmers encountered “neck rot” which the stem just rot and the whole plant become useless.

Factors that favoured disease developments

  • presence of infection bodies or sclerotia in the upper soil layer or on irrigation water
  • presence of wounds as entry points of the fungus
  • panicle moisture content
  • nitrogen fertilizer
  • presence of the white tip nematode, which has synergistic effect with the disease
  • from milking to ripening stages of the crop
