Rice-Wheat cropping system covers about 11 m ha in India, is the backbone of India's food security. This cropping system produces as high as 12.8 to 17.0 t/ha/annum at different levels of cultivation and is highly nutrient depleting but the factors responsible for success of this system are good economic return, market infrastructural support and very little risk making increasingly popular with the farmers over the years. The introduction of the non-sensitive, input responsive, relatively early maturing varieties of rice and wheat in the mid 60's enabled farmers to intensify land use and increased the acreage under this important cropping system. In recent years, there is a problem to sustain the high yield levels of rice-wheat in India. Several factors including attack of insect pests and diseases are considered responsible for stagnation in productivity of this cropping system. The present investigations were, therefore, carried out with a view to monitor insect pests, diseases and natural enemies operating in rice and wheat ecosystems and to develop an effective bio intensive management strategy to contain population buildup of major insect pests and diseases of rice and wheat.
Asian subtropics occupies 21 million hectares of rice-wheat cropping system on their fertile soils. This system carried out on 15 million hectares with highly significant impact for food safety in the area, providing staple food for more than 415 million people.Wheat (Triticum aestivum L.) has the highest position in food grains in Pakistan: 66% of the total area under food grains is wheat and it contributes 74% of the total food grain production.Tillage is done according to the soil types. Delay in wheat sowing is the result of 6-8 ploughing with planking and loss of high energy.Timely wheat planting after rice ensured in 10 percent higher wheat grain yield in a rice-wheat cropping system.Drilling of wheat in to rice residue using zero tillage has eliminated the time for land preparation and improved crop stand establishment.So,this study has, therefore, been planned to achieve the most economical method for sowing wheat in a rice-wheat cropping system and Quantify the nutrient losses to soil fertility of burning rice straw. Mushtaq Ahmad Gill is the founder of zero tillage and laser land leveling technology in Pakistan and contributed a lot for this research and book.
This book “Crop Residue Management in Rice-Wheat Cropping System” has written for plant nutrient management in rice - wheat cropping system with nitrogen and potassium fertilizers. The rice-wheat cropping system is one of most widely practiced cropping system in India as well as across the world. The nutrient management in this system is a big task; both crops are heavy nutrient feeder. It requires nutrient cycling from organic residues to maintain nutrient balance in soil. Addition of organic matter to the soil through the return of crop residues also improves soil structure, influences soil water, air and temperature relation, helps to control runoff and erosion and makes tillage easier. Therefore, use of renewable organic sources would be essential for sustainability of the rice-wheat system. This book provides the information about NPK nutrient balance and crop performance under crop residue management practices.
Dr. Y.V.Singh, Senior Scientist (Agronomy), IARI,New Delhi, India, has developed protocol for Basmati rice cultivation through organic management for sustainable productivity and better quality. In this protocol he used four (Blue green algae @ 2.0 kg/ha, Azolla @ 1.0t/ha/ Azotobacter @ 0.5 kg/ha, vermicompost @ 5.0 t/ha and Farm yard manure @ 5.0 t/ha) organic inoculants to meet the nutrient requirement of organic Basmati rice-wheat-green gram system and got
Conclusions drawn on the basis of the results obtained in the present investigation are stated below: 1. Combined application of N150 P60 K120 S40 B5 Mn20 Zn25 (kg ha-1) was the best dose of nutrients in hybrid rice under rice-wheat cropping system which produced highest grain yield (78.91and 75.00 qha-1durng both the years, respectively). It also improved soil fertility status measured as the available N,P,K,S and Zn. 2. For wheat after hybrid rice crop, the application of N150P60K120 kg ha-1 was found most suitable 3. Application of N150 P60 K120 S40 B5 Mn20 Zn25 kg ha-1 in rice showed residual effect on succeeding wheat crop as reflected in respect to grain and straw yields and all the nutrient treatment also improved soil fertility. 4. Application of N150 P60 K120 S40 B5 Mn20 Zn25 kg ha-1 in rice and N150 P60 K120 kg ha-1 in wheat (T1) increased soil available nitrogen, phosphorus, potassium, sulphur and zinc after harvest of each crop. 5. Application of N150 P60 K120 S40 B5 Mn0 Zn25 kg ha-1 in rice and N150 P60 K120 kg ha-1 in wheat (T8) was the best treatment and found most economical followed by T1.
The rice (Oryza sativa L.) - wheat (Triticum aestivum L.) cropping system occupies about 28.8 million hectares mainly spread over Asia’s five countries, namely, India, Pakistan, Nepal, Bangladesh and China. Organic farming offers alternative system for sustainable production and natural resource system. The aim of nutrient management in organic systems is to optimize the use of on–farm resources and minimize losses. Organic materials such as farmyard manure, compost, vermicompost, biogas slurry, green manures, crop residues, biofertilizers and cover crops are other valuable source of nutrients to improve the growth and yield attributes, yields, nutrient uptake, grain quality and soil fertility. The present book is a part of studies which is conducted to determine the optimum combination organic manures crop residues and biofertilizers for meeting nutritional requierment of rice-wheat and rice-wheat-mungbean cropping systems. It also focuses on studying the impact of organic farming practices on the health of soil, quality of organically grown products in order to find out economics of organic farming of rice-based cropping systems.
Residual effects of Zinc (Zn) fertilizer and farmyard manure (FYM) help in economizing the fertilizer use without any adverse effect on soil fertility and crop yields. No information is available for residual effect of Zn fertilizer applied in conjunction with FYM to rice-wheat rotation practiced in the northern plains, hot sub-humid (dry) ecoregion of India. The present investigation was carried out to determine the residual effect of Zn fertilizer application with or without farmyard manure on yields, cationic micro-nutrients (Zn, Cu, Fe and Mn) concentration and uptake of third crop rice and fourth crop wheat under rotation. The residual of conjoint use of 2.5 or 3.75 Kg Zn/ha + 5 t FYM/ha was found most beneficial for increasing both yields and nutrient uptake of both rice and wheat crops.
Pattern of temperature and precipitation are changing due to global warming. Impact of climate on agriculture has been a matter of concern for food security in India. Changes in temperature, precipitation, green gas emissions, droughts, sea level are likely to enhance the risk on agriculture. The impact of climate change on agriculture is being witnessed all over the world, but countries like India are more vulnerable in view of the huge population dependency on agriculture. Here, Agriculture sector supports the livelihood security to more than 60% population. Notwithstanding that, the crops like rice and wheat are the staple food for Indians. Monsoons are changing more frequently. Droughts, floods, tropical cyclones, hot extremes and heat waves are negatively impacting agriculture production. Increasing glacier melt in Himalayas will affect the food production. Impact of climate is more high compared to the past which increasing global warming, natural calamities and may result fluctuations on many crops. In this study, climate change and its impact on rice and wheat crops of India has been analyzed.
Rice-wheat cropping system in Pakistan covers almost 2 million hectares and pre-dominantly spreads across districts of Gujranwala, Sialkot, Norowal and Shiekhupura in Punjab. The present study was taken up as a start of a long-term study of fungal pathogens in rice-wheat cropping system in Pakistan in order to understand the biology of these, so that the knowledge so gained could be used to develop a strong disease management based largely on the host resistance. The study concentrated on root rot and foliar blight and associated fungi that were common to rice and wheat primarily. It has provided basic information on the prevalence and incidence of these diseases in the main four districts of rice-wheat areas of Punjab namely Gujranwala, Sheikhupura, Narowal and Sialkot. Fungi from root, foliage and soil in both wheat and rice crop were isolated and identified and their aggressiveness studied using pathogenicity analysis. Isolates of these fungi were genetically characterized using RAPD''s. The investigations were based on two surveys of wheat one in 1999 and other in 2000 done at the booting and heading stage of the crop covering 21 and 20 key locations of the area, respectively.
Wheat (Triticum aestivum) is an important cereal crop for a large number of countries in the world. It provides about 20% of total food calories for the human race.It is widely grown through the temperate zone and in some tropical and sub-tropical areas at higher elevation. It can be grown on a variety of soils ranging from sandy to heavy clay, for higher production fertile and well-drained loam to clay loam soil is most suitable. The major wheat growing countries in the world are USSR, USA, China, India, Canada, Australia, France, Turkey, Bangladesh and Pakistan. Among the major cereal grown in India, wheat stands second next to rice in area and production, but first in productivity among all the cereals. System of Wheat Intensification (SWI) popularly known as Sri Vidhi Gehun is different methodology for cultivation of Wheat. Its root goes in SRI principle being practiced in paddy. Here also all agronomic principles are put into practices and integrated with package of practices in wheat crop.
Wheat (Triticum aestivum L.) is considered to be one of the most important cereal crops belonging to grass family (Poaceae) having immense importance in Indian diet. On account of peculiar physical and chemical gluten, it makes better leavened bread than any other cereal. Wheat straw is important source of fodder for a large Indian animal population and also utilized in the manufacture of mattresses, straw and art purpose. Apart from food, the industrial use of wheat grain includes starch for paste, alcohol, oil and gluten. In India, wheat and rice serves as life sustaining crops for about 1.2 billion population and thus, considered to be backbone of nation’s food security system.
In India rationing system was introduced at the time of World War-II by the British Government. Through the rationing system the government provided rice, wheat and some of the other items to the ration card holders. It was carried out by the department of Food. After the war in 1943 the rationing system was abolished by the British Government. After Independence the government reintroduced the rationing system in 1950 to distribute food at low prices. It was called National Food Security System (NFSS). In order to strengthen the PDS, the government of India established the Food Corporation of India (FCI) in 1964. It ensures the Food security in our country. In this chapter an attempt is made to take a introduction and related review of the literature on public distribution system in India. The studies reviewed here are macro-level as well as micro-level based on secondary and primary data and conducted for different parts of the country.
Impact of Direct Seeding of Rice on Household Welfare in Pakistan Executive Summary The current study was carried out in the rice-wheat area of Pakistani Punjab to access the impact of direct seeding of rice sowing technology on household welfare in Pakistan. The direct seeding of rice (DSR) technology in Pakistan was introduced a couple of years back, with the idea to increase the crop yields and to save the use of inputs like water, fertilizer and labour. For estimating the impact detailed comprehensive survey was carried out in three main rice-wheat districts i.e. Gujranwala, Sheikhpura and Hafizabad. A detailed questionnaire was prepared for carrying out the analysis. The impact of direct rice sowing technology was estimated on rice and wheat crops yield, water, weedicide and labour demand. The empirical analysis indicates that adopters of direct seeding of rice sowing technology are getting higher net returns in the range of 8-9 maunds per acre. The comparative profitability analysis indicates that in case of direct seeding of rice sowing technology the cost of production is high than the conventional transplanting of rice but the net returns are more in case of direct seeding
The rice-wheat production system has major role in food security in the region and provides livelihood and income to millions of farmers in IGP. The lack of suitable mechanization and modernization with proper soil-crop management strategies is probably the cause of higher cost requirement and low return in the system. Current crop cultivation practices in rice-wheat systems degrade the soil and water resources thereby threaten the sustainability. The concept of alternative agricultural system is put forward to improve in net return with minimum resource use from crop cultivation is conservation agriculture (CA) the best alternative to protect soil, water, environment, time and cost. CA practices in Nepalese context have drastically reduced tillage intensity, reducing the cost of cultivation and allowing timely sowing with comparable yield.
The book evaluate the performance of canal irrigation system by using special scientific tools like Remote Sensing and Geographical Information System, so that proper measurements could be taken for the sustainable agriculture and water management. Different performance evaluation parameters had been calculated.The purposed data was gathered from field investigation and different government and private organizations. According to the calculations,organic matter ranges from 0.19% (low value) to 0.76% (high value). In comparison of flat and bed irrigation system in wheat crop,the water saving per acre varies from 46.51 to 56.5% of time. The average range of irrigation water saving at site was 51.37%, which provides evidence of 50% water saving in bed planting. Similarly, in rice crop, the range of water saving is 28.91 to 45% which happens due to over irrigation even in bed planting by same farmers. Results showed that on an average percentage yield increase in wheat bed planting fields varies from 11.83 to 29.4 % while 22.27 % increase in yield was obtained from rice bed planting in comparison with flat sowing.
