After having filled the seed trays on 27
December with our chosen varieties SL8 and 238, mechanical transplanting took
place on the 17th of January. As we decided as a group to grow our crop
ecologically and pesticide free, we did not to use any molluscicides and
instead attempted to protect our seedlings from snails by getting muddy and manually
collecting them.

In early December, to prevent the snail population growing
further, we had already drowned lots of pretty coloured pink eggs in the water.
Amazingly well over 10 kg (!) of snails were still collected in January before
planting.
One of the first challenges we gave ourselves
was to use a low amount of seed: 26 kg/ha (slight miscalculation of the field
size and miscommunication of sowing rates!). If we were manually transplanting,
this would have been ok, especially for the hybrid variety which grows well at
low densities. However, mechanical transplanting requires high densities of
seeds (1kg/m2) on the seed trays to allow the machine to pick some
up each time. A lesson we learnt the hard way after coming back from our
Christmas break. Due to the high seed densities sowed, we didn’t have enough
seed trays to cover the whole field using the transplanter. So, to account for
this, we had to plant with extra spaces between rows. Even though this was not a deliberate choice, we
hope the plants appreciate the additional space and the fact that they do not
have to compete with many other rice plants on their hill.

The next challenge came with water management! Common practice is to flood the field after fertilisation. Palay All Stars did not plant a Sub1 variety but due to some irrigation miscommunication our little seedlings had to learn how to live under water over a long weekend. As if that was not tough enough for our little plants, the water also helped the remaining snails to get around the field and help themselves to some leaves for their dinner. As the water was left on over a weekend, a lot may have overflowed into the drainage, potentially taking some of the fertiliser with it. Luckily we used the rotary weeder after fertilisation, which helped to incorporate the fertiliser into the soil. This means we have not lost all the fertiliser nor polluted the surface water too much!

As we did not have much spare seed, some
seedlings were taken from busy hills (you can easily separate the roots without
damaging after ‘washing’ them in the water so the mud comes off) and replanted
where snails or flood had caused gaps.
Our field looks a bit sad compared to the
neighbours but on the bright side, there is not much food for rats so they may
go elsewhere too!
