Human’s have used the sea for nourishing, getting raw material, advancing technology and providing transportation throughout history. The society have been destroying the eco balance as a result of the manufacturing technologies they use and demolishing many facilities of the future in the long run in an anxiety to earn their keep in the short run. The marine environment, which is the most convenient environment... Read more.

At least 70% of smallholders live in the semi-arid regions IV and V where rainfall is erratic and soils in these regions are derived from granite and generally shallow, light textured and of low fertility. As a result, farmers cannot produce adequate grain to meet their annual household requirements by dry land farming. The Zimbabwe/EU Micro-projects Programme has funded smallholder irrigation projects since 1982 to... Read more.

This study proposes a new drought index based on several precipitation-based parameters to quantify drought hazard in semi arid region. In addition to the practice of using only rainfall volume for indexing drought, the proposed index verifies the potentials of nine other precipitation effectiveness variables (PEVs) onset of rain, cessation of rain, length of rainy and dry season, wet days and dry days within a wet...

Various tillage practices can overcome the delay sowing of wheat in the rice-wheat cropping system of Pakistan to sustain the grain yield by increasing the nutrients and water use efficiency. A field experiment was conducted to evaluate the effect of different tillage practices (zero tillage and conventional) on growth and yield of four wheat (Triticum aestivum L.) cultivars viz. Inqalab-91, Chenab-2000,... Read more.

Tests were conducted to determine the effects of cold-storage of saffron (Crocus sativus L.) corms on the first and last flowering dates, harvest periods, saffron stigma yield, flower and leaf numbers, plant height, and asexual daughter corm reproduction in the field and glasshouse at the pre-planting stage. Corms stored at 8°C for 7 and 28 days were compared with controlled corms at room temperature storage at... Read more.

Changes in soil chemical properties, plant density and crops yield (maize, winter wheat, winter barley, soybean and oilseed rape) grown in soil contaminated by different degrees of crude oil and drilling fluids were monitored for three years. Drilling fluids had a stronger impact on chemical properties of the studied soil, while plant density and yield were strongly affected by crude oil. The influence of crude oil... Read more.

Witchweed (Striga sp.) is a noxious parasitic weed of many cereals, that causesconsiderable crop damage in the semi-arid tropics. Although, a number of control measures have been suggested, breeding crops which are resistant to the attack is the most feasible and effective way of control. However, breeding efforts have been hampered by the lack of adequate laboratory techniques that uncover critical host-parasite... Read more.

Cowpeas, Vigna unguiculata (Walp), are commonly attacked by Callosobruchus maculatus (Coleoptera, Bruchidae) during storage. Current methods to prevent losses during storage involve synthetic insecticides. Although they have insecticidal efficiency, these products have adverse effects on consumers and the environment. Plant products such as those of Xylopia aethiopica (Annonaceae) are... Read more.
