Adaptation Options

Potato is the most important non-cereal crop in the world and the most prominent winter season crop in India. Growth and yield of potato crop is very much sensitive to higher temperatures and the moisture stress. Hence, the anticipated increase of temperature due to global warming and climatic variability will have anadverse impact on potato production. Keeping this in view, a research work was carried out with the objectives to assess the impact of climate change on potato production and evaluating agronomic adaptation options through a crop growth simulation model (CGSM). Field experiments were carried out to prepare the minimum dataset for calibration and validation of one CGSM, namely InfoCrop. After validation, the model was used to predict the future tuber yield of ten selected stations situated under different agroclimatic regions of the State. In the future scenario 2050, the simulated yield for mid November planted crop likely to be about 11% less than the present level of mean yield. If the crop is planted in December, the percentage of yield reduction may be around 25%.The projected yield reduction, for the stations of higher latitude, is found to be negligible. Three possible agronomic adaptation options, viz., adjustment of date of planting, increase of seed rate and varying sprout length of seed tubers, have been tried as adaptation strategies to combat the adverse effects of climate change. It is concluded that the mid-November planting and longer sprout length will be the best adaptation option. However, the enhanced seed rate is not a viable adaptation option.

Low Volume

The history of the application of fungicides is one which shows a tendency to use ever decreasing quantities of spray liquid to the acre; the reason for this is obviously one of economics. The classification of various spray techniques is discussed with particular reference to the term ultra low volume. This may be defined briefly as the spraying of such extremely small volumes of liquid to the acre that it becomes impossible to use a simple aqueous medium as carrier. The reasons for this are given and the advantages of using special formulating agents noted.The success of the low volume technique of spraying potatoes for the control of blight is illustrated with a series of blight progress curves, showing that 5 lb of copper oxy-chloride applied at 50 gpa gives identical results to a similar rate of copper at 2 gpa. Copper estimations made on leaf samples from the top, middle and bottom leaves of a potato crop sprayed at 100 gpa and 5 gpa respectively show that the mass distribution of copper is much more uniform in the high volume plots than in the low volume plots. However, the largest quantities of copper are found in the top layers of the plots sprayed at low volume.

Potato is one of the most important vegetable crops in India accounting for 20-25% of area under cultivation of vegetables and grown in a wide range of climatic conditions. It is grown in almost all states under diversified agro-climatic conditions. Nearly 80% of the crop is grown in Indo- Gangetic plains comprising Uttar Pradesh, West Bengal, Punjab, Haryana, Bihar and other parts of India like Gujarat and Karnataka. Moreover, within the country, there is a lot of heterogeneity in potato productivity depending upon mostly on management and climatic conditions. The viability of commercial potato production is influenced by spatial and temporal variability in soils, agro climate, and the availability of water resources. The inter and intra-regional variations in productivity within the country are attributed to the variations in bio-physical factors vis-a-vis specific soil-climatic requirements of the crop. The present chapter discusses the impact of climate change on the land resources requirement for potato crop with reference to Indian context.

Bacterial wilt is a devastating plant disease caused by the bacterial pathogen Ralstonia solanacearum species complex and affects different crops. Bacterial wilt infecting potato is also known as brown rot (BR) and is responsible for significant economic losses in potato production, especially in developing countries. In Bolivia, BR affects up to 75% of the potato crop in areas with high incidence and 100% of stored potatoes. The disease has disseminated since its introduction to the country in the mid-1980s mostly through contaminated seed tubers. To avoid this, local farmers multiply seed tubers in highlands because the strain infecting potatoes cannot survive near-freezing temperatures that are typical in the high mountains. Past disease surveys have shown an increase in seed tubers with latent infection in areas at altitudes lower than 3000 m a.s.l. Since global warming is increasing in the Andes Mountains, in this work, we explored the incidence of BR in areas at altitudes above 3000 m a.s.l. Results showed BR presence in the majority of these areas, suggesting a correlation between the increase in disease incidence and the increase in temperature and the number of irregular weather events resulting from climate change. However, it cannot be excluded that the increasing availability of latently infected seed tubers has boosted the spread of BR.

Potato Growth

Narrow profit margins, resource conservation issues and environmental concerns are the main driving forces to improve fertilizer uptake, especially for potatoes. Potatoes are a high value crop with a shallow, inefficient root system and high fertilizer rate requirements. Of all essential nutrients, nitrogen (N) is often limiting to potato production. A major concern in potato production is to minimize N leaching from the root zone. Therefore, the main objective of this study was to examine the potato crop characteristics under drip irrigation with low-discharge (0.6 L h−1) and to determine the optimal combination of irrigation (40, 60, 80, and 100%) and fertigation (0, 50, and 100%) doses. In this study, the 80% (438.6 mm) irrigation dose and a 50% (50 mg N L−1) fertigation dose (W80%F50%) showed that these doses are sufficient for optimal potato yield (about 40 ton ha−1) in conjunction with water and fertilizer savings. Moreover, this treatment did not exhibit any qualitative changes in the potato tuber compared to the 100% treatments. When considering water productivity and yield, one may select a harsher irrigation regime if the available agricultural soils are not a limiting factor. Thus, higher yields can be obtained with lower irrigation and fertigation doses and a larger area.

The agriculture sector is reeling under the pressures of population, land and water scarcity, diseases, disasters and the most challenging of them all, climate change. Although climate change is yet to be charged with affecting agriculture, but in recent years trends of change have been witnessed in various crop production, with a hint of climate's role in it. With the advent of technology, these trends have become easier to analyse and in certain cases predict too. Information Technology (ICT) tools like Geoinformatics are playing a profound role in the agriculture sector and is helping to understand and assess the various factors affecting the growth of crops along with finding out the alternative suitability parameters for better production and distribution. The main aim of this chapter on agro-geoinformatics is to look into this linkage between technology usage and better potato production during adverse conditions.

Late blight caused by the oomycete Phytophthora infestans constitutes the greatest threat to potato production worldwide. Considering the increasing concerns regarding the emergence of novel fungicide-resistant genotypes and the general demand for reducing inputs of synthetic and copper-based fungicides, the need for alternative control methods is acute. Several bacterial antagonists have shown anti-Phytophthora effects during in vitro and greenhouse experiments. We report the effects of three Pseudomonas strains recovered from field-grown potatoes against a collection of P. infestans isolates assembled for this study. The collection comprised 19 P. infestans isolates of mating types A1 and A2 greatly varying in fungicide resistance and virulence profiles as deduced from leaf disc experiments on Black’s differential set. The mycelial growth of all P. infestans isolates was fully inhibited when co-cultivated with the most active Pseudomonas strain (R47). Moreover, the isolates reacted differently to exposure to the less active Pseudomonas strains (S19 and R76). Leaf disc infection experiments with six selected P. infestans isolates showed that four of them, including highly virulent and fungicide-resistant ones, could be efficiently controlled by different potato-associated Pseudomonas strains.

This study evaluated the potential distribution of the potato tuber moth. This species severely impacts global potato production, especially in China and India, which have the world’s largest potato production. We developed two indices considering host plant availability and production in addition to climatic suitability, which was simulated using the CLIMEX model. Thus, three different indices were used to project potential distribution of the potato tuber moth under a climate change scenario: (1) climatic suitability (ecoclimatic index (EI)) (EIM), (2) climatic suitability combined with host plant availability (EIN1), and (3) climatic suitability combined with host plant production (EIN2). Under the current climate, EIM was high in southern India and central to southern China, while EIN1 and EIN2 were approximately 38% and 20% lower than EIM, respectively. Under the Special Report on Emissions Scenario A1B, the potato tuber moth would probably not occur in India, but its distribution could be extended to the north, reaching N47°. The areas with the highest climatic suitability by potato tuber moth based on three indices were Sichuan and Karnataka in response to climate change. These areas require adequate pest control, such as prevention of spread through transport of potato seed or by using cold storage facilities.
