PADI SRI : 38 Hari Pertumbuhan Padi SRI di Selangor

Padi Berumur 38 Hari

Padi Berumur 38 Hari

Pada kali ketiga melandak, tenaga kerja Bangladesh sekali lagi terpaksa digunakan. Sekali ini lagi hebat pertumbuhan rumput bersaing dengan tanaman padi. Ada sebahagian tanaman padi yang mula menguning kerana persaingan makanan, iaitu yang tumbuh disebelah belakang di mana tanahnya tinggi dan kurang berair.

Mujurlah perkara ini dapat diatasi dan selepas 5 hari melandak, pokok-pokok yang menguning berubah manjadi hijau balik. Tapi nampak perbezaan pertumbuhan yang ketara diantara pokok padi yang mendapat air yang mencukupi dengan yang kurang. Oleh itu, perlu diambil perhatian yang berat kepada sesiapa yang ingin mencuba tanaman mengguna cara SRI ini. Tanah sawah sebaiknya mesti rata, seratanya.

Nazri pada masa ini mencuba pelbagai rekabentuk alat melandak yang di rekacipta olehnya sendiri. Nazri seorang yang kreatif dan mempunyai jentera membajak dua-rodanya sendiri. Juga mempunyai peralatan mengimpal. Dia telah menghasilkan beberapa prototaip alat melandak. Sila lihat gamabar di bawah. Yang paling mudah digunakan adalah yang paling belakang dalam gambar.

Beberapa hari kemudian Nazri menunjukkan alat melandak yang sama tapi kali ini dipetrikan pisau menajak yang tajam. Bermakna, alat melandak itu, selain dari merumput dan mengaerasikan tanah menggunakan pencakar yang bergerak, ia juga boleh memotong rumput-rumput yang tebal. Ini adalah kelebihan yang ada pada Nazri.

  1. Puan, may I get a list of total cost production incurred including man power. We need to compare SRI with the conventional system of planting. Plus, we can study the marginal returns (return to scale), labour intensive (although IADA BLS is the highest among other granaries, we need to compare SRI vs conventional)and other economic impact of the system.

    This is very crucial study need to be done to prove either the paddy industry have a tendency of the rate of profit to fall or we can increase the return in a long run.

    cheer 🙂

    • Salam. I think there are not much difference in both, except for organic compost, weeding/aerating the soil, and seed costs. Ok. Let’s work it out. Since my trial plot is only 1 acre, allow me to give you the costs for just so much. You will have to do the conversion to 1 hectare 🙂

      Land size = 1 acre

      Seed requirement = 2 kg/acre (with a 30 cm x 30 cm spacing with single seedlings per point) (Much less compared to conventional)

      Compost = 1 metric ton/acre (Very necessary for SRI to maintain the nutrient requirement for padi from nursery to harvest)

      In-field drains around the perimeter are necessary (RM100/acre) for managing water distribution in the field.

      The cost for manual transplanting was RM250/acre, that is using 5 persons for 8 hours. (The cost for machine transplanting is $400/acre). The concern is whether there is labour to do the transplanting in a large area. This is one area where machines can be very useful.

      Weeding/Aeration (melandak) = 4 times (RM 200 x 4 times) – after several seasons, this can be reduced to just 2 times. (This may be somewhat equivalent to the rouging practices of farmers for padi angin in transplanted rice) This is one area where machines can reduce the cost.

      Spraying organic fertilizer and biopesticides 4 times during the season. The cost of the organic fertilizers and biopesticides should be minimal because the farmers are expected to produce them. However, a cost of RM300 for the organic fertilizer/biopesticides plus the spraying is reasonable.

      The rest are quite the same (land clearing, plouging, rotovating, land-levelling, harvesting, etc). Please take into consideration that the costs are for a land that was previously a vegetable farm. I would like to see a comparison, and how we can benefit not just through high yields, but also by enhancing the fertility of the padi soil.

      Let’s work on this together. Wassalam.

      • Just a reminder, no chemical fertilizer or pesticides were used throughout the growing period. 🙂
