A gradual reduction in leaf water potential (Ψleaf), net photosynthetic rate (P N), stomatal conductance, and transpiration rate was observed in two drought tolerant (C 306 and K 8027) and two susceptible (RW 893 and 899) genotypes subjected to water stress. The extent of reduction was lower in K 8027 and C 306 and higher in RW 893 and RW 899. Rewatering(More)
Remote sensing is the science and art of obtaining information about an object through the analysis of data acquired by a device that is not in contact with the object (Lillesand and Keifer, 1994). Remotely sensed data can be of many forms, including variations in force distribution, acoustic wave distribution or electromagnetic energy distributions and can(More)
Yield datasets of long-term experiments on integrated nutrient management in rice-rice cropping systems were used to investigate the relationship of variability in rainfall, temperature, and integrated nutrient management (INM) practices in rice-rice cropping system in three different agroecological regions of India. Twelve treatments with different(More)
Polycyclic aromatic hydrocarbons (PAHs) are insurmountable pollutant that contaminates the soil and occurs frequently. The restoring of contaminated soil fertility is pricey and time intense process. Earthworms accelerate the removal of PAHs from contaminated soil by feeding and get better the soil structure and aeration of the soil. The main aim of this(More)
Rice–wheat (RW) production system, which covers over 13.5 million ha in the Indo-Gangetic Plains of south Asia, is vital for food and nutritional security and livelihood of millions of poor people in this part of the region. Availability of irrigation water under projected climate change scenarios is a great concern, and demonstration of the impact of(More)
Agricultural Drought is characterized by a deficient supply of moisture, resulting either from sub-normal rainfall, erratic rainfall distribution, or higher water with respect to a crop. In spite of technological developments in providing improved crop varieties and better management practices, in India, agriculture has been considered a gamble due to(More)
Chilli is one of the important spices and cultivated around the world for its peculiar hot taste. Chilli crops prone to affect by seedling disease called damping off. In order to overcome this problem, efforts have been made to evaluate the efficiency of the biocontrol agent Trichoderma harizanum for controlling the damping off disease in chilli. T.(More)
