In India, of the 49 million hectares (mha) of acid soil, 25 mha has pH below 5.5. Considerable genetic variability for aluminium (Al) tolerance exists in pea seedlings at intraspecific level, which has allowed the selection of tolerant and productive
genotypes for acidic soil.

Production of organic rice is a necessity of the present era. Hence, development of high-yielding rice varieties, suitable for a salinity stress area which is naturally an organic production system like the

The performance of the artificial neural network (ANN) model, i.e. standard feed-forward neural network trained with Levenberg

Cave fauna are unique and constitute one of the important components of biodiversity. The prevalence of cave organisms (cavernicoles) is always more in wet and longer caves compared to small and dry ones. Cavernicoles continue to evolve in the habitat characterized by complete darkness, constant temperature, high humidity and low predatic pressure.

In geochemical studies of water it is a general practice to filter the water samples through a 0.45 ?m membrane. Filtered samples are then acidified with a mineral acid (mostly nitric acid) to a pH

Spiders are gaining favour in ecological studies as indicators of environmental quality1 and as biological control agents in agricultural ecosystems. Coffee, a major commercial crop of India harbours rich spider diversity. The crop is also attacked by a variety of pests. This correspondence discusses the importance of gut content analysis of spiders in coffee ecosystem.
