it is known that legumes give benefits to the soil such as improved nutrient availability, improved structure, reduced pest and disease incidence, and hormonal effects (wani et al., 1995). the major benefit of legume crops comes from biologically nitrogen fixation, deriving from the symbiosis involving leguminous plants and rhizobium bacteria (vance, 1998). based on this purpose, a field study ...

Research project entitled “Yield and economic dynamics of intercropping in summer vegetables ” was conducted at Horticultural Research Farm, NWFP Agricultural University, Peshawar (Pakistan) during 1999 and 2000. Summer vegetables were evaluated alone and in various combinations for their yield, land equivalent ratio and income in intercrop combinations. Each plot was 4x4 m whereas number of ro...

Agroforestry has been widely practiced in the Loess Plateau region of China because of its prominent effects in reducing soil and water losses, improving land-use efficiency and increasing economic returns. However, the agroforestry practices may lead to competition between crops and trees for underground soil moisture and nutrients, and the trees on the canopy layer may also lead to shortage o...

Intercropping, which is the agricultural practice of growing two or more crops in the same land area, is not currently yielding adequate results in Africa. Despite the advantages of intercropping like improved soil fertility, protection against pests and diseases and eventual increase in farm yield, this farming practice is faced with challenges—inadequate planning, bad crop management and lack...

This experiment was conducted for two consecutive seasons of 2013/2014 and 2014/2015 at the Experimental Farm, Faculty of Agriculture, Zagazig University, Egypt, to evaluated the effect of different intercropping patterns (safflower: fenugreek at different row ratios; 1:1, 1:2 and 1:3 in comparison with sole cropped of each specie), different foliar fertilization levels (0, 2 and 4 g/l) and the...

Although muscle metabolism and exercise capacity seem to be affected in patients with subclinical hypothyroidism, there is little evidence indicating improvement of the exercise tolerance due to levothyroxine (L-T(4)) replacement. The aim of the present study was to verify possible cardiopulmonary changes during exercise in patients with subclinical hypothyroidism on L-T(4) replacement with a n...

As the major crops in north China, spring crops are usually planted from April through May every spring and harvested in fall. Wheat is also a very common crop traditionally planted in fall or spring and harvested in summer year by year. This continuous cropping system exhibited the disadvantages of reducing the fertility of soil through decreasing microbial diversity. Thus, management of micro...

An experiment to study the feasibility of intercropping the short duration agronomical crops in periwinkle was conducted at Nagarjun Medicinal Plants Garden, P.K.V. Akola during 1988 - 89, 89 - 90 and 90 - 91. The highest monetary return of Rs. 15,604/ per hectare was obtained from an intercropping system of periwinkle and groundnut is row proportion of 2:1.
