Adoption, Management, and Impact of Hybrid Maize Seed in India AgEcon
Singh, R.P.; Morris, Michael L..
This paper presents results of a 1995 survey of 864 maize-growing households in six states that account for more than 70% of India's maize area: Andhra Pradesh, Bihar, Karnataka, Madhya Pradesh, Rajasthan, and Uttar Pradesh. The current adoption of improved open-pollinated maize varieties (OPVs) and hybrids is quantified, the relationship between adoption of improved germplasm and use of improved crop management practices is examined, the economic impacts of adoption are estimated, farmers' seed procurement and management practices are described, and implications for maize research and development policy are discussed. On the whole, the survey results confirm that India's national maize seed industry is expanding rapidly. Since seed policy reforms were...

Adoption of Resource Conservation Technologies in Indo-Gangetic Plains of India: Scouting for Profitability and Efficiency AgEcon
Singh, N.P.; Singh, R.P.; Kumar, Ranjit; Vashist, A.K.; Khan, Farida; Varghese, Nisha.
This study has evaluated the superiority of resource conservation technologies (RCTs) over conventional methods of cultivation and has identified the factors influencing adoption of these technologies. It has provided succinct evidences from four states — Bihar, Haryana, Punjab and Uttar Pradesh — by comparing the adopters and non-adopters of RCTs in the rice-wheat cropping system of the Indo-Gangetic Plains of India. The study has highlighted superiority of RCTs over the conventional practices in terms of cost saving and efficient inputs-use. However, there is a need to internalize the RCTs in their totality by applying plans and strategies based on local dynamics. The study has suggested the need of policy formulations for dissemination and wider...

Concerns of Groundwater Depletion and Irrigation Efficiency in Punjab Agriculture: A Micro-Level Study AgEcon
Jeevandas, Anupama; Singh, R.P.; Kumar, Ranjit.
The present study, conducted during 2005-06, in two districts, viz. Amritsar and Faridkot of Punjab, (former having pre-dominantly tubewell-irrigated area and the latter having canal + tubewell irrigation facilities) has assessed the extent of water depletion and has measured irrigation efficiency at the farm level. Due to profitability and availability of water at shallow depths during 1970s, paddy and wheat (two of the high water-consuming crops) replaced other crops like maize, groundnut and pulses in the entire state. The area under these two crops increased from 7.22 per cent to 32.92 per cent for paddy and from 37.12 per cent to 43.53 per cent for wheat, from TE 1965 to TE 2005. Consequently, the problem of groundwater depletion has become severe in...

Diversification of Indian Agriculture: Composition, Determinants and Trade Implications AgEcon
Singh, N.P.; Kumar, Ranjit; Singh, R.P..
The pattern of diversification across states/crops in India has been schematized and various determinants of diversification have been deciphered. To objectively confer the empirical resonance, values of Simpson index have been estimated. The diversification index (SID) has been found to range from 0.47 (WB) to 0.90 (Karnataka) in 1990-91 and from 0.40 (Orissa) to 0.92 (Karnataka) in 2000-01. The increase in diversification Index signifies shift towards non-foodgrain crops. In Karnataka, though the Index has increased, but the similar increases in area under foodgrain imply shift from coarse to fine cereals. Agricultural diversification is influenced by a number of infrastructural and technological factors. The coefficients have indicated that the presence...

Economic evaluation of the Happy Seeder for rice-wheat systems in Punjab, India AgEcon
Singh, R.P.; Dhaliwal, H.S.; Humphreys, E.; Sidhu, H.S.; Manpreet-Singh; Yadvinder-Singh; Blackwell, John.
Burning of rice stubbles is widely practised in Punjab, India, due to a lack of suitable machinery to direct drill wheat into combine-harvested rice residues. Although burning is a rapid and cheap option, and allows quick turn around between crops, it has serious effects on human and animal health due to air pollution, reduced soil fertility due to loss of nutrients and organic matter, and green house gas (GHG) emissions. The recently developed Happy Seeder (HS) overcomes the technical problems associated with direct drilling into rice residues. The primary aim of the present study was to conduct a preliminary evaluation of the direct financial benefits and costs to farmers of use of the HS in comparison with the current practices of straw burning followed...

Enhancing Sustainable Development of Diverse Agriculture in India AgEcon
Singh, R.P.; Singh, N.P.; Kumar, Ranjit.
Agriculture in India occupies an important place as it contributes nearly 25 per cent of GDP and two-thirds of the population depend upon it. Agricultural growth in the past has been sufficient to move from severe food crisis to aggregate food surplus today. The rainfed regions are diverse in terms of resource base, varying from resource rich regions harnessing substantial production to resource poor regions with restricted potential. These resource poor regions are mostly dominated by secondary crops. Barring maize and potato, secondary crops are loosing ground against the finer cereals, cash and commercial crops. Therefore, there is an urgent need to provide a leverage to these crops by providing support in terms of technological advancement and policy...

Extent of Groundwater Extraction and Irrigation Efficiency on Farms under Different Water-market Regimes in Central Uttar Pradesh AgEcon
Srivastava, S.K.; Kumar, Ranjit; Singh, R.P..
Tube-well irrigation, through modern water extraction mechanisms (WEMs), has been vital to food security and sustainable livelihoods in India. However, due to skewed distribution of WEMs towards large farmers on account of huge investment needs, small and marginal farmers have to rely on owners of WEMs for irrigation water. This has resulted in the emergence of informal water-markets. The present study has examined the groundwater extraction and water-use efficiency under different water-market regimes in the Central Plain Zone (CPZ) of Uttar Pradesh, where water-intensive cropping pattern is followed. The study is based on the primary data collected from 100 farmer-households of Central Plain Zone in the year 2007. Most of the farmers in the study domain...

Is Futures Market Mitigating Price Risk: An Exploration of Wheat and Maize Market AgEcon
Singh, N.P.; Kumar, Ranjit; Singh, R.P.; Jain, Praveen Kumar.
Instability of commodity prices has always been a major concern of the producers as well as the consumers in an agriculture-dominated country like India. Farmers in a bid to avert the price risk often tend to go for distress sale and thereby reduce the potential returns. In order to cope up with this problem, futures trading has emerged as a viable option for providing a greater degree of assurance on the price front. Thus, futures markets serve as a risk -shifting function. In the present study, an attempt has been made to look into the mechanism of movement of spot and futures prices for two important food crops in Indian agriculture. The Augmented Dickey Fuller (ADF) test has been used for both the crops to check the stationarity of the time series...

Labour Migration in Indo-Gangetic Plains: Determinants and Impacts on Socio-economic Welfare AgEcon
Singh, N.P.; Singh, R.P.; Kumar, Ranjit; Padaria, R.N.; Singh, Alka; Varghese, Nisha.
In India, male out-migration from rural to urban areas has increased in recent years, especially in the Indo- Gangetic regions of the country. This indicates that most of the developed regions of India are utilizing labour force of backward areas. The paper has investigated on labour out-migration from the states of Uttar Pradesh and Bihar to find its determinants and its impacts on farm economy. The analysis of determinants shown that the number of members in a family and their educational status have a positive impact on migration. As a result of male out-migration, the women left behind in the villages assume a major role in various farm activities resulting in the so-called ‘feminization of agriculture’. It has also empowered the female members of the...

Structure, Determinants and Efficiency of Groundwater Markets in Western Uttar Pradesh AgEcon
Singh, D.R.; Singh, R.P..
Irrigation is a vital ingredient in the modern agriculture, groundwater development through modern water extraction mechanisms (WEMs) have therefore, been receiving greater emphasis in recent past. However, the ownership of private WEMs is confined mostly to the large farmers. The small and marginal farmers and even large farmers with fragmented holdings are buyers of irrigation water from the neighbouring WEM-owners. This has led to spontaneous emergence of groundwater markets. Although the water markets benefit both buyers and sellers in one or the other way, they have created certain implications in the utilization of this resource. The present study has examined the structure, determinants and efficiency of groundwater markets and has suggested policy...

Sugar Industry in Uttar Pradesh: Efficiency Still Holds the Key AgEcon
Singh, N.P.; Singh, Paramatma; Singh, R.P..
The sugar industry is a major agro-based industry of Uttar Pradesh where cropping pattern is largely subsistence-oriented and sugarcane is one of the important cash crops. During 2001-02, the state had 20.35 lakh ha area under sugarcane out of the total 44.03 lakh ha area under sugarcane in the country. The sugar industry has shown considerable instability in the level of production as a result of inter-dependence and inter-relationship between sugarcane, gur, khandsari and white sugar, leading to fluctuations in the production of sugarcane as well as sugar. These fluctuations emanate from the presence of various processing sectors and the differential governmental policies. Such an uncertain state of affairs is neither conducive to sound growth of the...

Technical Efficiency in Maize Production in Madhya Pradesh: Estimation and Implications AgEcon
Anupama, J.; Singh, R.P.; Kumar, Ranjit.
The state of Madhya Pradesh is one of the traditional maize growing states, accounting for 13 per cent of the total maize area and contributing equally to the total maize production in the country. However, its productivity when compared to other maize growing states is very low. The study has found that even though a majority of the farmers cultivate improved maize cultivars, the overall technology adoption by them is poor. This may be due to the inability of a majority of farmers to follow the recommended package of practices for the improved cultivars because of the high costs involved in their adoption and lack of infrastructural facilities. Therefore, steps need to be initiated to solve this problem. A comparison of costs on cultivation of...
