Direct seeded rice farming can lessen pressure on groundwater

RAJSHAHI, May 24, 2017 (BSS) � Agriculture specialist Prof Moshiur Rahman said large-scale promotion of direct seeded rice (DSR) farming can be the vital means of lessening the existing overrated pressure on groundwater in drought-prone Barind area.

He added water scarcity, water loving nature of rice cultivation and increasing labour wages triggers the search for such alternative crop establishment methods which can increase water productivity.

DSR is the only viable option to reduce the unproductive water flows, added Prof Rahman from Department of Agronomy of Bangladesh Agricultural University, Mymensingh.

He said this while presenting his keynote paper at a scientific seminar at conference hall of Barind Multipurpose Development Authority (BMDA) here yesterday. BMDA hosted the seminar titled "Crop Intensification with less water through Dry Direct Seeded Boro Rice Based Cropping System".

Chairman of BMDA Dr Akram Hossain Chowdhury attended and addressed the seminar as chief guest with its Executive Director Engineer Abdur Rashid in the chair.

Prof Moshiur Rahman says DSR refers to the process of establishing a rice crop from seeds sown in the field rather than by transplanting seedlings from the nursery. It has been recognized as the principal method of rice establishment since 1950's in developing countries.

Referring to salient feature of it Prof Rahman said direct seeding can be done by sowing of pre-germinated seed into a puddled soil or standing water or prepared seedbed.

Improved short duration and high yielding varieties, nutrient and weed management techniques encouraged the farmers to shift from traditional system of transplanting to DSR culture.

Direct seeding offers certain advantages like saving irrigation water, labour, energy, time, reduces emission of greenhouse-gases and better growth of succeeding crops.

Quoting his research findings he showed statistical evidence that in the most conservative estimate, 50 percent less water was required for growing rice with equally productive yield.
