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...

Impact of Arbuscular mycorrhizal fungi (AMF) in sugarcane productivity was assessed through a field experiment from plant and ratoon sugarcane in Tamil Nadu, India. Control, 12.5 and 18.75 kg ha-1 of AMF along with 75% and 100% of phosphorous application were triedas treatments. 18.75 kg ha-1 AMF applied plots showed significant difference in germination percentage, tiller number, internode...

The losses of nitrogen (N) fertilizer applied to the soil microenvironment reduce its efficiency. Different strategies like use polymer coating and chemical nitrification inhibitors had been employed N losses. But these are very expensive. Thus, a study was conducted investigate effects different concentrations Parthenium extract, neem oil, acidulated cow dung compost extract on dynamics in soi...

BACKGROUND: Overuse of fertilizers can lead to groundwater contamination, depletion of soil microorganisms and beneficial insects, increased crop susceptibility to diseases, acidification or alkalization of soil, damage to soil structure, reduced organic matter and soil fertility. Therefore, for achieve sustainable agricultural, it is necessary to reduce the consumption of conv...

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...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

Compost is very important for the soil and useful in increasing productivity agricultural production a sustainable manner where quality quantity are achieved, as well reducing enviromental pollution improving of land (soil) manner. This study aims to determine effect chemical fertilizers market waste compost addition on vegetative growth oil palm seedlings main nursery. The research was carried...

BACKGROUND Blind and excessive application of fertilizers was found during the cultivation of Panax notoginseng in fields, as well as increase in root rot disease incidence. METHODS Both "3414" application and orthogonal test designs were performed at Shilin county, Yunnan province, China, for NPK (nitrogen, phosphorus, and potassium) and mineral fertilizers, respectively. The data were used ...

Nitrogen deficiency limits crop performance under elevated CO2 (eCO2), depending on the ability of plant N uptake. However, the dynamics and redistribution of N2 fixation, and fertilizer and soil N use in legumes under eCO2 have been little studied. Such an investigation is essential to improve the adaptability of legumes to climate change. We took advantage of genotype-specific responses of so...

Two cultivars each of four warm-season grass species under three N fertilizer treatments and three harvesting regimes were studied to determine the effect of nitrogen fertilizer and harvest date on forage yield. Research was conducted in eastern Nebraska on an alluvial soil. The eight grasses studied were 'Blaze' and 'PM-K-129' little bluestem [Schizachyrium scoparium (Michx.) Nash], 'Cave-in-R...
