No-till rice experiment - 2017

In the no-till area, last year I tried cowpea followed by green gram basically to reduce grass weeds. It is not that clean, meaning still there are grass and some other creepers. Anyway, this year planning to do rice cultivation in this field when monsoon starts.

In one area, I dumped some dried leaves in order to control weeds, in another area planning to grow green gram, black gram combination for two months and then start rice. While rice is growing, planning to sow moth beans as a legume which will act as a live mulch. Started to make seed balls so that cover crop can grow with first rain and before grass grows strong.

Here are some photos...

Leaves collected in an old bed sheet..

Moth beans seed

Seed balls of green gram..used hibiscus leave juice as binding agent, it looks to be better...since seed is smooth, with water, soil does not stick well and peels off when dried..

Seed balls made in a basin ...white ant soil powdered using a hammer and then sieved it to get finer particles. Seeds were made wet using Hibiscus leave extract and then soil added slowly and then mixed seeds with soil in the basin, this process continued...1 Kg of green gram seeds were completed in 1.5 hours....

Waiting for rain, got only one or two drizzling...Mean while made seed balls of happy hill rice and wanted to put before the rain starts. When visited the field there were some grass growing, in some areas of the farm, all the grass has dried up, here may be because of no-till more moisture and hence grass still grows. So used my Honda brush cutter and cut the grass and sowed the happy hill rice seed balls and mulched using leaves. Since at this stage, not clear which plan will work, wanted to experiment with many trials. These are the different plans which I can think of now, may change as it goes....

1. The one which I did just now, cut the grass and sown happy hill rice seed balls and wait for rain. Idea of putting seed balls early is to make rice germinate and grow with the first rain, either ahead or along with weeds. 

2. Grow green gram and black gram for 2-3 months, sow seed balls of traditional rice seeds ,then cut and mulch, by this time rain would have started. 

3. Grow forage maize for 2-3 months, sow seed balls of traditional rice seeds,cut and mulch, forage maize is supposed to give better weed control since it decomposes slowly, but whether rice seedlings can push through the mulch to be seen.

In all these cases prepared to do some hand weeding and applying cowdung slurry.

Some photos of the field...

Happy hill rice seed balls, came out quite well... Since seed surface is rough, mud holds seeds well.
