Abstract Aims Gypsum soils are P-limited atypical soils that harbour a rich endemic flora. These singular soils are usually found in drylands, where plant activity and soil nutrient availability are seasonal. No previous studies have analysed the seasonality of P nutrition and its interaction with the arbuscular mycorrhiza fungi (AMF) colonisation in gypsum plants. Our aim was to evaluate the seasonal changes in plant nutrient status, AMF colonisation and rhizospheric soil nutrient availability in gypsum specialist and generalist species. Methods We evaluated seasonal variation in the proportion of root length colonised by AMF structures (hyphae, vesicules and arbuscules), plant nutrient status (leaf C, N and P and fine root C and N) and rhizospheric soil content (P, organic matter, nitrate and ammonium) of three gypsum specialists and two generalists throughout a year. Results All species showed arbuscules within roots, including species of Caryophyllaceae and Brassicaceae. Root colonisation by arbuscules (AC) was higher in spring than in other seasons, when plants showed high leaf P-requirements. Higher AC was decoupled from inorganic N and P availability in rhizospheric soil, and foliar nutrient content. Generalists showed higher AC than specialists, but only in spring. Conclusions Seasonality was found in AMF colonisation, rhizospheric soil content and plant nutrient status. The mutualism between plants and AMF was highest in spring, when P-requirements are higher for plants, especially in generalists. However, AMF decoupled from plant demands in autumn, when nutrient availability increases in rhizospheric soil.

The Relationship

Healthy soil could support plant growth by optimizing the availability of nutrients. The availability of nutrients influences the health of tea plants. Nutrient deficiencies would affect the plant physiology that exhibits the plant withering. This study aimed to define the relationship between soil nutrient availability with plant nutrient uptake. This research was conducted by managing secondary data soil chemical properties, and tea plant nutrients analyzed statistically with Pearson correlation. This study only found a significant correlation between soil pH with P and Mg uptake. Correlation results between soil nutrient and plant nutrient uptake obtained a significantly negative correlation on soil pH with P and Mg nutrients with a correlation value of pH-P (r=-0.52), pH-Mg (r=-0.52). There was no correlation between other soil nutrients and plant nutrient uptake. The results of this study can be used to determine the dose of fertilization and the management recommendation of tea plants.

The field experiments were conducted in farmer's field at five locations each of kole lands to study the effect of Magnesium (Mg) on yield and soil and plant nutrient status of rice during 2012-2013 and 2013-2014. The experiment was laid out in randomized block design with three replications. The treatments comprised of different levels of Mg viz; 40, 60, 80, 100, and 120 kg Magnesium sulphate(MgSO4)/ha along with control. Observations on growth characters yield attributes, yield and soil and plant nutrient status were recorded. The results revealed that application of 100 kg MgSO4 / ha recorded the maximum number of panicles/m2 (419.13), number of grains/panicle (109.36), thousand grain weight (28.78 g), grain (9.27 t/ha) and straw yield (9.04 t/ha) of rice. The results of pooled data on plant and soil nutrient status revealed that application of magnesium had a positive effect on nutrient content and availability of nutrients in soil. A significant positive correlation was also noticed between Mg application, yield attributes, yield and nutrient contents. The study concluded that application of 100 kg MgSO4 / ha was found to be optimum for correcting the deficiency in Mg deficient areas of kole lands under below sea level farming.

Fruit Stage

Primocane-fruiting blackberry (Rubus L. subgenus Rubus, Watson) cultivars, Prime-Jan® and Prime-Jim®, grown only for a primocane crop, were studied for 2 years to evaluate whether this type of blackberry should be sampled at a certain stage of development or time of season to best evaluate plant nutrient status. Leaves were sampled every 2 weeks from a primocane height of ≈0.75 m in spring through fruit harvest in autumn and were analyzed to determine concentration of macro- and micronutrients. Primocanes were summer pruned at 1.4 m, by hedging to a height of 1.0 m, to induce branching, a standard commercial practice. Leaf nutrient concentration was related to stage of primocane growth and development and whether the leaves originated on the main cane or on the branches that resulted from summer pruning. Nutrient concentration of leaves sampled on the main primocane from early growth in spring until early branch growth in summer was significantly affected by cultivar, year, and week for most nutrients. When leaf sampling occurred on the older leaves of the main cane (for 4 weeks after hedging), the concentration of Ca, Mg, B, Fe, Mn, and Al increased, likely a result of the relative immobility of most of these nutrients. When samples were taken on primocane branches, leaf N, Mg, S, B (2009 only), Fe, Mn, Cu (2009 only), Zn, and Al concentrations did not differ between samples taken 6–8 weeks after summer pruning or hedging. Leaf K and Ca were more stable when sampling was done from weeks 8 to 10 (early bloom to green/early red fruit). There was a significant difference in leaf P among all weeks sampled during this period. A sample date corresponding to early green fruit stage (week 8) would thus likely provide the best compromise for assessing plant nutrient status in this crop. During this stage of development the nutrient concentrations measured for both cultivars and years, were within the present recommended nutrient sufficiency levels for other blackberry and raspberry crops for all except leaf K and P which were below current standards. The results suggest leaf sampling primocane-fruiting blackberry at the early green fruit stage (about 8 weeks after summer pruning) rather than a particular calendar date. The present leaf sufficiency range for P and K may need to be lowered for this crop. In addition, sampling cultivars separately for tissue analysis would still be advised to better manage nutrient programs.

Abstract. Enset (Ensete ventricosum) is a productive, drought-tolerant and multipurpose food security crop grown in the densely populated Ethiopian highlands. Its production suffers from poor soil fertility management and a bacterial wilt disease caused by the pathogen Xanthomonas campestris pv. musacearum. The aim of this study was to assess soil-plant-nutrient variation within enset home gardens over three different altitudes (ranging from 2000–3000 masl) in the Chencha catchment of the Gamo highlands and investigate whether this variation affects disease prevalence. Plant available P, Ca and Mg significantly increase with decreasing elevation but significantly decline with distance from the house. In addition, soil pH, conductivity, total organic carbon (TOC), total N, available K, Mn and Fe levels significantly decline with distance from the house. This indicates that soil fertility factors are influenced by both agro-ecology and farmers' management practices. Moreover, most nutrients reach very high levels in the garden whereas the more distant outfields are severely nutrient deprived. Plant nutrient levels are not correlated to soil nutrient levels except for N. Twenty two percent of the studied farms are symptomatic for bacterial wilt and its prevalence increases with decreasing elevation. Symptomatic gardens have a higher soil pH and available P, K and Ca levels. We conclude that soil fertility management in enset gardens should be optimized in relation to agro-ecological conditions and that both elevation and soil nutrient status need to be considered when developing strategies to curb the current Xanthomonas wilt epidemic.

The uptake of nutrients by the paddy crop better indicative of the fertility, productivity, and plant nutrient status. The main objective of this investigation was that the rate of nutrient application can influence the removal of nutrients into formsavailable to the soil with different landraces in conjunction with the application of different microbial inoculants under different fertility levels. The yield of landraces was significantly influenced by the microbial inoculants under different fertility levels.Significantly higher uptake of N, P and K was observed in the landrace padmarekha compared to other landraces. The nutrient removal from the soil was in the range of 81.57 – 104.08 kg N, 19.55 -33.96 kg P and 88.15 – 111.81 kg/ha Kamong landraces. Similarly, the higher uptake was seen with the application of 100 per centRDF along with the azospirullum, Bacillus megatherium var. Phosphoticum Frateuria quaratia,Thiobacillus thiooxidans and Vesicular ArbescularMycorrizae.The nutrient removal was in the range of 47.11-122.0 kg N, 10.71-36.7 kg P2O5 and 34.22- 141.21 kg/ha K2O among fertility levels in different paddy landraces used in the study. The different microbial inoculants application with the recommended dose of fertilizers in different levels helped in the acquisition of the nutrients from the soil solution illustrating the effects of microbial applications through the increased supply of biologically fixed nitrogen, mobilizing the phosphorus towards plant roots, and potassium availability to the crop. Thus, our investigations acclaim that there is a need to inoculate the crop with different microbial inoculants to increase the use and uptake of the nutrients by the crop and improvement in soil nutrient status.
