- Guidelines for dry seeded aman rice (DSR) in Bangladesh(IRRI, 2014) Gathala, M.K.; Sudhir-Yadav; Mazid, M.A.; Humphreys, E.; Ahmed, S.; Krupnik, T.J.; Rashid, M.H.; Chauhan, B.S.; Kumar, V.; Russell, T.; Saleque, M.A.; Kamboj, B.R.; Jat, M.L.; Malik, R.; Tiwari, T.P.; Mondal, M.; Rahmand, M.; Saha, A.; Hossain, K.; Saiful Islam; Mcdonald, A.Dry seeded rice (DSR) is becoming an attractive option for farmers as it has a much lower labor requirement than manually transplanted rice. Labor for transplanting rice has become scarce and costly because laborers are shifting from agriculture to industry, public works and services, and migrating abroad. DSR can be readily adopted by small farmers as well as large farmers, provided that the required machinery is locally available (e.g., through custom hire from agricultural service providers). Best practice involves using a 2- or 4-wheel tractor-drawn drill to seed in rows into nontilled or dry tilled soil, as for wheat. Because the soil is not puddled, DSR also has a lower water requirement for crop establishment, and may require less frequent irrigation than puddled transplanted rice grown with alternate wetting and drying water management during dry spells. Where arsenic contaminated groundwater is used, less irrigation means less arsenic brought to the soil surface. Furthermore, accumulation of arsenic in the grain and straw is much less if the soil is allowed to dry between irrigations to let air (oxygen) into the soil (“aerobic” conditions) than in continuously flooded rice.

Publication - Guidelines for Dry Seeded Rice (DSR): in the Cauvery Delta Zone, Tamil Nadu, India / Sudhir Yadav and others(CSISA, 2014) Sudhir-Yadav; Ganeshamoorthy, R.; Humphreys, E.; Rajendran, R.; Ravi, V.; Mussgnug, F.; Kumar, V.; Chauhan, B.S.; Ramesh, T.; Kamboj, B.R.; Gathala, M.K.; Malik, R.; Jat, M.L.; Mcdonald, A.Dry seeded rice (DSR) is becoming an attractive option for farmers in the Cauvery Delta Zone (CDZ) due to the elimination of the labor requirement for nursery preparation and maintenance, pulling out and transport of seedlings, and transplanting. Because the soil is not puddled, DSR also has a lower water requirement for crop establishment. Furthermore, the total crop cycle is shorter by 10−15 days because of the absence of transplanting shock. These features of DSR are of major importance for the Cauvery Delta (see below) because of the increasing scarcity of water for irrigation in the area. DSR can be readily adopted by small farmers as well as large farmers, provided that the required machinery is locally available (e.g., through custom hire). Best practice involves using a 2- or 4-wheel tractordrawn drill to seed in rows in dry or slightly moist soil.
Publication - Guidelines for dry seeded rice (DSR) in the Eastern gangetic plains of India(IRRI, 2013) Yadav, S.; Malik, R.; Humphreys, E.; Kumar, V.; Singh, S.S.; Bhagirath, S.; Kamboj, B.R.; Gathala, M.K.; Jat, M.L.; Mcdonald, A.; Laik, R.Dry seeded rice (DSR) is becoming an attractive option for farmers as it has a much lower labor requirement than manually transplanted rice. Labor for transplanting rice has become scarce and costly because laborers are shifting from agriculture to industry, public works, and services. This document is meant to be a guideline for the production technology of DSR in Bihar and Eastern Uttar Pradesh (Eastern Gangetic Plains) India.
Publication - Operational manual for turbo happy seeder: technology for managing crop residues with environmental stewardship(CIMMYT, 2013) Jat, M.L.; Kapil; Kamboj, B.R.; Sidhu, H.S.; Singh, M.; Bana, A.; Bishnoi, D.K.; Gathala, M.K.; Saharawat, Y.S.; Kumar, V.; Kumar, A.; Jat, H.S.; Jat, R.K.; Sharma, P.C.; Sharma, R.; Singh, R.; Sapkota, T.; Malik, R.; Gupta, R.K.Multiple challenges associated with plough based conventional production practices that include deteriorating natural resources, declining factor productivity, yield plateau, shortages of water & labour and escalating costs of production inputs coupled with emerging challenges of climate change both in irrigated intensive systems as well as low intensity rainfed ecologies are the major threat to food security of South Asia (Jat et al, 2009; Ladha et al, 2009; Chauhan et al, 2012). Water and labour scarcity and timeliness of farming operations specially crop establishment under the emerging climatic uncertainties are becoming major concerns of farming all across farmer typologies, production systems and ecologies in the region (Chauhan et al, 2012). In many parts of South Asia, over-exploitation and poor management of groundwater has led to declining water table and negative environmental impacts. Conventional tillage based flooded rice receiving the largest amount of fresh water compared to any other crop is the major contributor to the problems of declining groundwater table ranging from 0.1– 1.0 m year-1 specially in north-west India and increasing energy use and costs. The problem has further been intensified with the unavailability of labour in time, and multi-fold increase in labour costs. Fragmented land holdings and nucleus farm families further exacerbates the problem of availability of farm labour. Potential solutions to address these issues include a shift from intensive tillage based practices to conservation agriculture (CA) based crop management systems (Saharawat et al, 2010; Jat et al, 2012; Gathala et al, 2013). Direct drilling (seeding/planting with zero tillage technology) is one such practice that potentially addresses the issues of labor, energy, water, soil health etc (Malik et al 2005; Gupta and Sayre, 2007; Jat et al, 2009; Ladha et al, 2009; Gathala et al, 2011; Jat et al, 2013) and adaptations to climatic variability (Jat et al, 2009; Malik et al, 2013). One of the key elements of CA is rational soil cover with organics (crop residues, cover crops etc) has greater relevance not only in terms of managing the agricultural waste but particularly for eliminating burning, improving soil health, conserve water, help in adaptation to and mitigating of climate change effects. Globally, annual production of crop residues is estimated at 3440 million tonnes of which large quantities are not managed properly. In India alone, more than 140 million tonnes of crop residues are disposed of by burning each year. In rice-wheat system of the IGP of South Asia, the disposal of rice residues is one of the major challenges due to poor quality for fodder, bioconversion, and engineering applications. In most combine harvested rice fields of western IGP, the rice residues are burnt before planting of wheat. The field burning of crop residues is a major contributor to poor air quality (particulates, greenhouse gases), human respiratory ailments, and the death of beneficial soil fauna and micro-organisms. During burning of crop residues around 80% of carbon is lost as CO2 and a small fraction is evolved as CO. Burning involving incomplete combustion can also be a source of net emissions of many greenhouse gases including CO, CH4, SO2 and N2O. Crop residue burning accounts 6.6 million tonnes of CO2 equivalent emission annually in India (INCCA, 2010). Apart from loss of carbon, up to 80% loss of N and S, 25% of P and 21% of K occurs during burning of crop residues (Ponnamperuma, 1984; Yadvinder-Singh et al., 2010). For managing residues of combine harvested crops and field (loose as well as anchored) as surface mulch and realize multiple benefits of improve crop yields, conserve soil moisture, saving of irrigation, buffer soil temperature, improve SOC, adapt to terminal heat effects in addition to environmental benefits through eliminating burning, ‘Turbo Happy Seeder’, is now available, which is capable of direct drilling (ZT) into heavy surface residue loads in a single operation. Many of the farmers in India and elsewhere have started using Turbo Happy Seeder for residue management. However, one of the major constraints in large scale adoption of this technology as well as sub-optimal use efficiency of planter is the lack of skills/knowledge on operation, calibration and maintenance of the machinery. There are different field situation specific adjustments needed before the use of the machine in the field. These adjustments include proper seeding depth, fertilizer rate and the seed rate etc as per the crop and field conditions to realize the potential benefits of the technology. There are several machinery manufacturers who supply these planters but the operational manuals are not available for making adjustments, calibrations under local conditions. In absence of the proper operational guidelines and protocols for efficient use of this machine by the farmers, service providers, extension agents, many a times the desirable results are not achieved and even contradictory results are observed. This results in slow down the adoption rates of the technology. Also, in absence of simple guidelines for maintenance of the machine, the farmers/service providers need to make huge investments on repairing at the start of the season. Therefore, we attempted to develop an operational manual to provide simple guidelines for calibration, operation, maintenance and troubleshooting for efficient use of turbo happy seeder by the range of stakeholders including farmers, service providers, extension agents and researchers.
Publication - Sprayers and spraying techniques: a manual(CSISA, 2012) Malik, R.; Pundir, A.; Shahnawaz Rasool Dar; Singh, S.K.; Singh, R.G.; Shankar, P.R.; Singh, N.; Jat, M.L.Timely application of herbicides, pesticides and fungicides (collectively called Crop Protection Products-CPP) at peak periods plays a vitalrole in ensuring better yields from a crop. The magnitude of this problem is further amplified due to shortage of labour during this time. Hence, mechanization of application is the only viable option in this scenario. Correct Equipment selection for CPP application is the most important issue we need to address for effective pest and weed control. The choice of equipment depends on its specific use and the need for a particular pest-weed control measure. Studies indicate that seventy percent of the success of CPP depends on the effectiveness of its application. In India, improper and ineffective methods of application have resulted in a tremendous waste of CPPs. This has led to the damage of non – targeted plants and has decreased CPP effectiveness while posing extensive health hazards for humans and animals alike. This makes a call for the need of a manual on CPP application technologies. This manual intends to work as a practical guide to extension workers and farmers. It aims to answer the following questions. What is the best way to apply a CPP? How do I know what nozzle to use? How do I calibrate my equipment? What are the precautions I should take before spraying? Why is it important to clean and maintain my sprayer?
