1 Hybrid rice- Jharkhand Impact of Private R&D returns and Productivity of Hybrid Rice in India Carl E. Pray Agricultural, Food and Resource Economics Dept Rutgers, the State University of New Jersey Presented at the ICABR meetings, Rome, Italy (June th, 2011)

2 The Issues of Current Debate in India and elsewhere in Asia (and Africa??) 1. Yield growth and in some cases actual yields of rice in India, China, and other intensively farmed regions appear to be declining 2. Private sector R&D in Rice has grown rapidly is this R&D actually leading to higher yields on farmers fields? 3. Who benefits from these hybrids? a. Seed companies or farmers or both? b. Can small farmers benefit? c. Can food insecure (i.e. poor, rainfed) regions benefit? 2

4 Rice Research Investment by Private Firms in India Firms with R&D (Number) R&D Expend for rice (Mill. Rs) Share of the Hybrid rice market (%) < Source: Pray and Ramaswami (2001); Pray and Nagarajan(2011) ICAR initiated Hy Rice research support from UNDP MAHYCO Res Foundation Nearly 10 % of total R&D expenses of firms is allocated for rice

5 Rice Seed Market in India ( ) Variety use Area Yield / ha % % Kg/Ha Public/Local varieties Public hybrids Proprietary hybrids Source: Francis-Kanoi Data on Paddy, India ( ) Of the total rice market in India - 94 % under OPVs/Local 95 % of the hybrid rice market Private sector Leading firm Bayer (45 % of quantities and value sold) Other lead players include Pioneer, Advanta, Nath, JK Agri, Syngenta, Mahyco and Bioseeds Total hybrids developed till : 28 (Public); 15(Private)

9 Diffusion of proprietary rice hybrids in India Major concentrations of hybrid rice are in the eastern states of (eastern) UP, Jharkhand, Orissa, Bihar Cultivated under medium, upland and low land conditions Northern states of Haryana and Punjab Cultivated under low lands and irrigated Adoption in western and southern India is negligible due to Grain quality constraints Agro-ecological no hybrids for shallow low lands, coastal areas, and soils Insufficient yield advantage over existing MVs (<10-15%)

10 Impacts : 1. Yield Impact in hybrid rice growing regions of India State All rice varieties & hybrids Private Hybrids Varieties Bihar Haryana Jharkhand Maharashtra Orissa Punjab Uttar Pradesh Eastern U.P Private hybrids On an average 800 kg/ha than all varieties (OPVs) Public Hybrids yields were found only in Punjab and Haryana Average yields of public hybrids reported are 7100 and 7200 kg/ha respectively. 10

11 Econometric estimate impact of proprietary hybrids on yields Data source: Francis-Kanoi Marketing Research Firm, Chennai, India syndicated study on rice-paddy in India(2009) 14 major rice states, covering 139 districts and 11,500 farmers Of the 14 states, 7 states only reported hybrid rice acreage 96 different cultivars of rice 58 OPVs and 36 private hybrids, 2 public hybrids OLS estimation with an empirical specification: Yield c,s = f ( Seed rate c,s + Private Hybrids Dummy c,s + Pesticide or Fertilizer cost s + % rice under irrigation s + % of farms under 5 acres s + # of years hybrids grown s ) c= cultivar(hybrids or varieties), s=state 11

13 Results..yield impact Impact of private rice hybrids on yields is positive The impact of rice hybrids on yields are significant in eastern and northern states than western state of Maharashtra Seed rates are negatively related to yield perhaps because farmers in with better water control are more likely the transplant paddy while in areas with poor water control and in medium and upland regions more farmers broadcast seed using more seeds but get lower yields. Higher pesticide expenditures are positively related to yields but state irrigation levels are not % of small farms in the state is also not significant (but district level results show more robust results) 13

14 Projected benefits of private hybrids to seed firms and farmers Indicators (P) 2015(P) Yield Impact Additional output from private hybrids over HYVs a (Mill.

15 Measuring returns to private research on rice Benefits to Society 95 % of hybrid rice area in India is proprietary origin 17 % increase in average yields (900 kg/ha) over the existing HYVs at the national level Additional output gain due to hybrids : 989 million kg ( ) worth Rs 12 billion (US$ 266 million) 90 % of these benefits go to farmers Benefits captured by firms Mean seed price paid per kg of hybrids is Rs.74.4/Kg compared to Rs. 30.1/Kg for varieties Capture 7.5 % of the benefits or Rs 753 million (US$ 16.7 million) as net income (not incl. research expenses) in Internal rate of return to private rice research expenditure 7 to 8% 15

16 Small food insecure farmers benefit from rice hybrid cultivation a. Hybrid rice yields by farm size (Kg/ha) at the district level HYVs/Local Public Private Land size varieties Hybrids Hybrids Up to 2 acres to 5 acres to 10 acres Over 10 acres Total b. Average yield comparison in food security districts (kg/ha) Food security districts HYVs/Desi Public Hybrids Private Hybrids Total

17 Back to initial issues Hybrids are contributing to yield growth particularly in regions which the Green Revolution missed. Private R&D is providing most of the hybrids and these hybrids have higher yields Who benefits from these hybrids? a. Farmers get 90% of benefits, private firms 7.5% b. Small farmers are obtaining benefits their gains per ha are greater than large farmers c. Farmers in food insecure districts (i.e. poor, rainfed) regions are also benefitting partly due to govt subsidies 17
