Issues related to direct seeding of rice in rainfed cropping systems in northwest Bangladesh
Economic factors and developments in rice production technologies are the major drivers that have led to the adoption of direct seeding of rice in place of transplanting in Asia. The primary economic motives for a shift to direct seeding are the savings in labor cost and the possibility of crop intensification. A key development challenge in the drought-prone rainfed agriculture of the Barind Tract of northwest Bangladesh is to simultaneously improve the reliability and yield of monsoon rice while improving total system productivity by increasing the area planted to drought-tolerant postrice crops. Research trials and field-scale evaluation by farmers have demonstrated that dry direct seeding or wet seeding of pregerminated
rice seed reduces labor for crop establishment, results in rice yields similar to or higher than those from conventional transplanting, and advances harvest by
7-10 days. Earlier harvest has the potential to reduce the risk of terminal drought in rice when the monsoon ends abruptly and increases the opportunity for establishing
a postrice crop of chickpea on residual moisture. Herbicide use is essential with direct seeding and this further reduces rice production costs. This modified
rice/legume system using direct seeding is knowledge-intensive. Widespread sustained adoption will depend on farmers undertaking timely tillage, adequate land
leveling, and timely application of herbicides. Extension/farmer training supported by clear decision support frameworks will be needed to provide farmers with access to the knowledge needed to implement direct seeding effectively
Energy use and efficiency in selected rice-based cropping systems of the Middle-Indo Gangetic Plains in India
The use and cost of energy in agriculture have increased, making it necessary to make current agricultural practices more energy efficient. To do this, the prevailing systems must be thoroughly analysed. Studies have focused on assessing the energy performance of individual crops, but notably few studies have investigated different cropping systems. This paper aims to assess the energy performance of the two most used cropping systems of the Indo-Gangetic plains in India, namely Paddy riceâWheat (PW) and Paddy riceâPotato (PP). The PW system was more energy efficient with Energy Use Efficiency (EUE) of 6.87 ± 1.7 compared to 3.61 ± 0.58 for the PP system. Higher Energy Efficiency Ratio (EER) (3.94 ± 1.30) and Specific Energy(4.39 ± 2.06) (SE) were reported for the PW system, compared to 2.62 ± 0.47 and 2.15 ± 0.35 respectively for the PP system. Fertiliser use accounted for the highest input energy consumption in both systems, accounting for 58% and 51% of the energy consumed in PW and PP systems respectively, followed by fuel, seeds and electricity. The net income from the PP system (2295.7 ± 457.4 USD.haâ1.yrâ1) was higher than that from the PW system (1555.4 ± 856.6 USD.ha1.yrâ1). The higher return of PP system was attributed to higher yield and better market price for the potato produce. There were no significant differences reported for various energy and economic parameters within different farm sizes in the PP system. However, for PW system, small farms were energy efficient while larger farms were economically efficient
Optimizing Production Technology for Sustainable Organic Fodder Production and Soil Health in Indo-Gangetic Plains of India
Field experiment was carried at Instructional Dairy Farm, G B Pant University of Agriculture & Technology, Pantnagar (India) during 2020-21 and 2021-22 to optimize the production technology for sustainable organic fodder production and soil health in Indo-Gangetic plains of India. Among the organic production systems, application of vermicompost @ 5 t/ha gave the highest fodder yield, gross return and net return but the B:C ratio was derived highest from zero budget natural farming. Among the Kharif crops grown in different cropping systems, BN hybrid intercropped with cowpea gave the significant higher green and dry fodder yield, gross return, net return as well as B:C ratio. Therefore the BN hybrid intercropped with cowpea may be grown under zero budget natural farming for higher fodder productivity and B:C ratio in whole Indo Gangetic plains of India and may be replicated in similar ecologies
Increasing Health Threat to Greater Parts of India Due to Crop Residue Burning
Rice crop residue burning during mid-October to November every year is becoming a serious health threat because of increased burning by farmers in the states of Punjab, Haryana, and western Uttar Pradesh in northern India. Crop residue burning started in the late 1980s with the start of mechanised harvesting in Punjab. Farmers found burning to be an economical way of cleaning crop stalk residues that are left over by mechanised harvesters. In doing so, farmers ignore the impact of this practice on health and air quality in the cities located in the Indo-Gangetic Plains. In the winter season, the severity of this problem increases as dispersion of smoke plumes is slowed down because of cold temperatures, whereas during the summer season the problem does not exist because of fast dispersion of plumes from burning. The practice of crop residue burning that started in Punjab has slowly spread to other adjoining states in northern India. We have found that the impact of crop residue burning on air quality is not restricted to cities in the Indo-Gangetic Plains alone, but is spreading to the far eastern parts of the Indo-Gangetic Plains and over central and southern parts of India, including parts of Bihar, Jharkhand, West Bengal, Madhya Pradesh, Chhattisgarh, Odisha, Telangana, and Maharashtra. We used diverse climate datasets derived from different NASA space platforms as well as global climate models and ground stations for our analysis
Water productivity in agriculture: a review of empirical evidence for selected Asian countries and India
In the context of the growing demand for water and the emerging water crisis, this paper examines the prospects for improving water use efficiency in agriculture that will help water savings and also increase crop yields per unit of water input. Evidences from experimental or farmer participatory trials in a cross section of regions, countries, sites in Asia and the Indo-Gangetic plains suggest that alternate agronomic and crop management practices such as zero-tillage, bed planting, non-puddled rice culture and laser leveling can result in water savings and also improve rice and wheat yields per unit of water input.Length: pp.214-225Irrigation efficiencyWater productivityRiceWheat

Crop-livestock interactions and livelihoods in the Gangetic Plains of West Bengal, India: findings from a scoping study
The research and development community faces the challenge of sustaining crop productivity gains, improving rural livelihoods and securing environmental sustainability in the Indo-Gangetic Plains. This calls for a better understanding of farming systems and of rural livelihoods, particularly with the advent of, and strong advocacy for, conservation agriculture and resource-conserving technologies. The paper summarizes the findings from a scoping study to assess crop-livestock interactions and rural livelihoods in the Gangetic Plains of West Bengal, drawing from a village survey in three districts (Malda, Nadia and W Medinipur) and secondary data. The rice-cattle based rural livelihoods are in stark contrast with those in the western Indo-Gangetic Plains, whereas the stateâs high human and livestock pressure and high poverty pose particular challenges to sustainable intensification and poverty reducing agricultural growth â particularly in the more remote districts. Strengthening the client orientation and productivity of the agricultural R&D community will be central to improving livelihoods and more sustainably using natural resources â and research on crop-livestock interaction serves as a good entry point for that process
Labour Migration in Indo-Gangetic Plains: Determinants and Impacts on Socio-economic Welfare
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 âfeminization of agricultureâ. It has also empowered the female members of the migrant households in terms of enhancing their decision-making role in various activities. The study has observed some policy implications in terms of formation of self-help groups or labour societies to help out-migrants, organization of training programmes for capacity building of women, more thrust on education a girl-child and development of infrastructure in the rural areas.Labour migration, Feminization of agriculture, Farm-women empowerment, Impact on farm socio-economy, Agricultural and Food Policy, J61, J23, J31,
