Seed Crops

A detailed analysis of technical means and methods of seeds separation, as well as the research results of domestic and foreign authors, have proved that one of the perspective methods for getting of high quality seed material is the pneumatic and electric separation.The analysis of research works and the modern technical level of pneumatic separators showed that insufficient attention was paid to the study of aerodynamic separation of small-seed crops, especially, cereal grasses. By the conditions of separation in a vertical pneumatic channel the cereal crops change the area of the midlength section as to the air flow forces, and the probability was increased of getting of seeds with germs to a biologically defective seed without germs. To increase the quality of pneumatic separation one can by the selective orientation of seeds in mixture with longer axis perpendicularly to the flow of air. It is possible to achieve these conditions by the additional force action on seeds (as particles). The response of this force action could be different for a healthy seeds (with germs) and for a non-viable (without embryo) or a weed seed. Such a force effect on the particles of small-seed crop mixtures can be realized by creating of a homogeneous electric field in a separation channel. This requires a theoretical and experimental study of force action on particles during the process of separation, also justification of parameters and operating modes of the pneumatic electric separator. This study is the preconditions for design improvement of the pneumatic electric separator.

Zinc Application

Green gram is one of the most important kharif pulse crops of India. It is of short duration, can fit well in crop rotation and, therefore, can be grown throughout the year. Information has been accumulating concerning the role of potassium and zinc in cereal crops but very little information is available regarding the nutrition of potassium and its interaction with zinc on the yield and quality of pulses. However, Malewar, Budhewar & Jadhav (1980) and Ghildiyal, Saini & Sirohi (1975) have reported significant positive effect of zinc treatment on growth attributes in green gram. The present investigations were, therefore, planned to study individual and interaction effects of potassium and zinc on growth, dry-matter and grain yield and quality of green gram.

Phloem Feeder

Abstract D. noxia has a great economic impact on cereal crops (Brooks et al., 1994). It is a phloem feeder like other aphids and the symptoms evident on plants are a result of this feeding mechanism. By feeding on the phloem, the aphid damages the plants through nutrient drainage (Dixon, 1985) which results in chlorosis, necrosis, wilting, stunting, and curling of the leaves, misshapen or nonappearance of new growth, and localised cell death at the site of aphid feeding. D. noxia further elicits an increase in essential amino acids in the phloem sap by triggering the breakdown of proteins in infested wheat leaves (Burd and Burton, 1992; du Toit, 1986; Ma et al., 1998; Miller et al., 2001). The damage to the foliar tissue is thought to play a role in the pest's ability to increase nutritional quality of the host plant (Botha et al., 2006).

Spatial Environment

The spatial relationships and growth of individual plants were studied in barley and wheat crops to determine the influence of size and distance of neighbouring plants on the development of individuals within the population. Plants were harvested individually, and their positions recorded by X and Y coordinates. The dry weights within quadrats were categorized in 10 weight classes and plotted for visual analysis. A reciprocal equation was used to relate the weight of individual plants to 'competitive pressure' of near neighbours. The estimate of competitive pressure was based on the weight and distance of neighbours. Both visual analysis and numerical analysis failed to find a direct effect of space available or the location of near neighbours on the growth of individual plants. It is suggested that in dense cereal crops differences in time of emergence and quality of soil environment may over-ride the advantage of an increased spatial environment for individual plants.
