When fish are recovered from ponds, the effluent is often drained, presenting both an environmental challenge and an agricultural opportunity. The effects of irrigation with pond effluent and its interaction with applied fertilizer were assessed in a field experiment using French bean (Phaseolus vulgaris) and kale (Brassica oleracea) over two growing seasons near Sagana, Kenya. Fresh and dry ma...

  To predict growth and yield, it is needed to study sub-models of phenology, dry matter production and partitioning, leaf area variations and soil water balance. In the present study, for predicting yield of maize under Isfahan conditions, parameters of the sub-models in the aforementioned model were estimated using data of planting dates between 1988 and 2004 in Isfahan region and data of oth...

The objective of this work was to study the effects of tillage and liquid manure applications on some physical and chemical properties as well as on the carbon and nitrogen mineralization potential of a meadow soil. Our results indicated that tillage and manure applications had no effect on the concentration of Cu, Mn, total N and organic C in 0-15 cm layer of soil after 15 years of treatment. ...

The objective of this study was to evaluate effects of cow manure on soil hydraulic properties and bromide leaching in a sandy loam soil (coarse loamy mixed, Typic Torrifluvents). Manure was applied at 0, 30, and 60 tha-1 at three replications in a completely random design. Three months after manure application potassium bromide (KBr) at rate of 300 Kg ha-1 Br was uniformly applied on the surfa...

Alternative forages can be used to provide valuable home-grown feed for ruminant livestock. Utilising these different forages could affect the manure value and the implications of incorporating these forages into farming systems, needs to be better understood. An experiment tested the hypothesis that applying slurries from ruminants, fed ensiled red clover (Trifolium pratense), lucerne (Medicag...

In order to determine the response of some tropical grass species to low light situations such as under plantation crops, seasonal cloud cover, etc., six tropical forage grasses were evaluated over a 20 month period on an Oxic Haplustoll in Hawaii (100 m above sea level) under four light regimes (100, 70, 45, and 27/, daylight using polypropylene netting) in the field. The forage grasses evalua...

A two-year study was conducted to determine the effect of three depths of furrow and three plant row spacing, on irrigation water efficiency, yield and yield components of watermelon (Crimson Sweet cultivar) using a strip split plot arranged in a randomized complete block design with three replications. Three depths of furrow (15, 35 and 55 cm) were considered as horizontal factor and three pla...
