A field experiment was conducted on Chickpea-Mungbean-T.Aman cropping pattern at Pulses Research Sub-Station, Madaripur under Low Ganges River Floodplain Soils (AEZ-12) during 2007-08 and 2008-09 to find out the suitable fertilizer doses for this pattern. Four treatments were set up for each crop. For chickpea and mungbean, the treatments were T1=Recommended fertilizer dose as per FRG, 2005 BAR...

C urrently recommended N management in North Carolina and elsewhere in the humid southeastern USA is based on realistic yield expectations (RYE). In North Carolina, N recommendations based on RYE are made from a database of RYE by soil map unit or based on a grower's documented historic yields (the average of the best three yields during a 5-yr period; North Carolina Nutrient Management Workgro...

The mechanism associated with improvement of soil nutritional status by oilseed rape crop, leading to better performance of rice crop, in rice-oilseed rape cropping systems is little known. The present study was aimed to test the hypothesis that earthworm casts produced during oilseed rape-growing season have positive effects on grain yield and fertilizer nitrogen (N) utilization in the subsequ...

The Iowa soil-test interpretations and fertilizer recommendations for phosphorus (P) and potassium (K) were last updated in 1996 and 1999. The 1996 update involved the most important changes compared with previous recommendations. New soil-test P and K interpretation classes (very low, low, optimum, high, and very high) were developed to classify soil-test values into two sets corresponding to ...

A greenhouse pot test was conducted to study the impacts of replacing mineral fertilizer with organic fertilizers for one full growing period on soil fertility, tomato yield and quality using soils with different tomato planting history. Four types of fertilization regimes were compared: (1) conventional fertilizer with urea, (2) chicken manure compost, (3) vermicompost, and (4) no fertilizer. ...

this study evaluated the irrigation water management and different amounts of boron fertilizer affacts on yield and and water use efficiency of sugar beet. the two-factor factorial design in randomized complete block with three replications of irrigation and different levels of boron fertilizer for three years (2000-02) was designed in qazvin. the main four irrigation treatments were t1, t2, t3...

The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...

Received for publication ply 8, 1974 Nitrogen (N) fertilizer management for sugarbeet (Beta vulgaris L.) production requires more precise information than for most crops. Inadequate N limits plant growth and root yield, but excess N may reduce both sucrose percentage and recoverable sucrose (7)." Also, excess N may stimulate more leaf growth than necessary. The rate and timing of N fertilizer a...

Mulching and nitrogen are critical drivers of crop production for smallholders of the Loess Plateau in China. The purpose of this study was to investigate the effect of mulching and nitrogen fertilizer on the soil water content, soil nitrate-N content and vertical distribution in maize root-zone. The experiment was conducted over two consecutive years and used randomly assigned field plots with...

A pot experiment was conducted to examine the effects of.various fertilizers on the dynamics of soil-borne DDTs and their subsequent impacts on DDTs uptake by a test plant. The results show that there was a significantly lower soil residual DDTs concentration in the iron-rich fertilizer-treated soil than in other fertilizer-treated soils. However, all the non-iron-rich fertilizers showed no sig...
