Pollution from Paddy Straw Burning Can be Reduced by Growing Pigeonpea Instead, says CEA Arvind Subramanian

Chief Economic Adviser Arvind Subramanian has proposed cultivation of arhar or pigeonpea by farmers in Punjab and Haryana as a way to combat pollution caused by the burning of paddy straw.  The development of a new variety of pigeonpea by a team of the Indian Agricultural Research Institute led by its Joint Director (Research) K V Prabhu is promising, he writes in the Indian Express. This variety, called Pusa Arhar-16 matures in 120 days and has a high yield of about two tonne per hectare, against an average of less than one tonne for varieties now being grown. It also grows uniformly making it amenable for mechanical harvesting. The stalks can be ploughed into soil where they decompose quickly, unlike paddy straw, which takes time to degrade because of high silica content.

Subramanian says the current methodology to fix support prices adopted by the Commission on Agricultural Costs and Prices focuses exclusively on private costs and benefits. It does not account for the social costs ─ the claim that paddy makes on groundwater and the pollution caused by burning straw in fields.  On the other hand, the social benefits of pigeonpea are ignored. The crops requires very little water and its stores nitrogen absorbed from air in nodules which enrich the soil. Pigeonpea is also a riskier crop as it is prone to pest attacks.  To compensate its minimum support price should be higher than this kharif season’s Rs 5,050 per quintal.

The committee headed by the CEA on augmenting the supply of pulses had estimated the social benefit of pulses at Rs 13,240 per hectare. It had suggested an MSP of Rs 9,000 per quintal for them over the medium term so they could compete with paddy.

Calling for sustainable agriculture, the CEA says the country must encourage agricultural science and research especially where India’s scientists have done the hard and creative work.  Agricultural research institutions must be free from political interference, they must be given autonomy and must reward talent.

To make science commercially viable, price incentives will have to be re-evaluated to account for risks and social benefits.

The large-scale burning of paddy straw is an opportunity to implement a major shift in policy that can reduce pollution while promoting indigenous science and research.  “Converting crises into opportunity is the hallmark of good public policy,” he says.

I Do Not Understand Bt Cotton technology; I Know It Works

Y Kallanagouda Patil, 46, of Uppinbetegeri village in Dharwad taluk  owns 52 acres jointly with his three brothers. He holds a diploma in agriculture from a school in Raichur. Patil grows cotton on ten acres, apart from sugarcane, potato, Bengal gram, jowar, tur,moong and vegetables. He uses groundwater to irrigate his fields. The water is drawn from a depth of 280 feet. Electricity is free so he flood irrigates the fields, except the one under banana  where he uses drip irrigation. He does not micro-irrigate cotton because it is closely planted and has to make way for another crop after eight months. This farmer has his cost all worked out. Making quick mental calculations, he estimates the cost of cotton crop at Rs 22,500 an acre and the realization from 17 quintals an acre at Rs 68,000. He had planted Bayer seed. ‘I do not understand technology, he says, all I know is if I use Bt seed there will be no

Pests Snack on Chilly But Not Cotton

F Basavaraj Rudagi, 48, did not grow cotton before 2008. This farmer from Saundhi village in Dharwad district’s Kundogol taluk made a partial switch to Bt cotton as chilly was susceptible to pest attack and yield was declining. From five acres in 2009, Rudagi had fifteen of a forty acre joint farm under cotton this year, when smartindianagriculture  caught up with him in February. He tried out Bayer in a change from Mahyco and Raasi seed. Rudagi says he got 11.5 quintals (100 kg) an acre from his rain-fed crop and at Rs 4,050 a quintal, his realization was a little over Rs 46,000. The cost, he says, is Rs 26,000 an acre, excluding rental earnings had he leased out the land. This does not mesh with the profit he claims he makes, but then he admits to not keeping crop-wise accounts. Rudagi also grows peanuts, coriander, gram, safflower and jowar. There is safety in diversity. And yes he plants pigeon pea or tur around the cotton crop for bollworms to feed on so they are not forced by the survival instinct to develop resistance to Bt protein.  In this sense he is quite a cut apart. Low cotton prices are worrying but what is the alternative?
