A field experiment was conducted during Rabi season of 2012-13 at Regional Agricultural Research Station, Lam, Guntur, with an aim to find out the effect of foliar nutrition on water potential, photosynthetic rate, dry matter production and yield of mung bean under receding soil moisture conditions in split plot design with irrigation and no irrigation as main treatments and foliar sprays as su...

Soil moisture condition is one of the key parameters in environmental and agricultural modeling. In this paper, a modified triangle method (Ts/VI space) is suggested. Both NDVI and EVI are used in constructing the space. Based on this method we calculated the Temperature-Vegetation Dryness Index (TVDI) using 20 MODIS images (Land surface temperature and vegetation index products) to estimate th...

Three experiments were conducted to find out the feeding type and age structure of nematodes in different soil habitats; to know the efficiency of different extraction techniques of nematodes and to observe the hatching behavior of Meloidogyne juvenile in a Baermann device. Bacterivore, Omnivore, Predator, Fungivore and Plant Parasitic nematodes were recorded in the soil of flower, vegetable, m...

Information of spatial and temporal variations of soil quality (soil properties) is required for various purposes of sustainable agriculture development and management. Traditionally, soil quality characterization is done by in situ point soil sampling and subsequent laboratory analysis. Such methodology has limitation for assessing the spatial variability of soil quality. Various researchers i...

A comprehensive management program for urban hemlock, Tsuga canadensis (Carriere) under pressure of Tsugae adelges (Annand) is presented. Hemlock management includes assessment of hemlock condition noting HWA infestation and its impact to tree health, soil and tissue analyses, therapeutic intervention(s), and application of soil amendments to manage environmental stresses. The key to optimizing...

Calligonum mongolicum is a successful pioneer shrub to combat desertification, which is widely used for vegetation restoration in the desert regions of northwest China. In order to reveal the limitations to natural regeneration of C. mongolicum by asexual and sexual reproduction, following the process of sand dune stabilization, we assessed clonal shoots, seedling emergence, soil seed bank dens...

The problem of calculating transient heat transfer in concrete floor slabs is complicated due to ground coupling, which can require the numerical solution of two or three-dimensional transient conduction equations. This paper presents a simplified method for calculating transient slab-on-ground heat transfer that can be incorporated within hourly simulation programs. The method assumes that the...
