Usually these types of salinity frequently co-exist. Neutral salts generally induce osmotic stress and ion-induced injury to growing crop plants. Behavior of AS may be different due to high pH. This study was conducted to see the response of wheat growth and Na<sup>+</sup>/ K<sup>+</sup> ratio under AS and NS application as nutrient solution study. Germinated disinfected seeds of wheat (Cv. Pak-13) and raised in sand. Ten days seedlings were transferred to pots containing standard nutrients solution, with the application of 30 and 60 mM of NS (NaCl, Na<sub>2</sub>SO<sub>4</sub>) and AS (NaHCO<sub>3</sub> and Na<sub>2</sub>CO<sub>3</sub>) separately in 1:1 ratio using complete randomize design in triplicates. The seedling growth period in salt solution comprised 33 days. Biomass and the selected inorganic ions were affected significantly (p&lt; 0.01) under salt stress. The magnitude of loss of bio mass was 11 percent higher in AS than that of NS application. Phosphorus and sulphur concentration were lower 10 and 7 percent with AS than NS respectively besides high Na<sup>+/</sup>K<sup>+</sup> ratio and pH.&nbsp; Further such studies on salt tolerant crop varieties can be carried out to differentiate response under different types of salts.</p> Badar-Uz-Zaman ., Huda Khan, Muhammad Suhaib, Muhammad Ishaq, Muhammad Arshadullah, Imdad Ali Mahmood ##submission.copyrightStatement## http://journalasrj.com/index.php/ASRJ/article/view/30057 Wed, 15 Jan 2020 00:00:00 +0000 Response of Cocoyam (Xanthosoma mafafa) Growth, Yield Parameters and Soil Physical Properties of Ultisol at Umudike, Southeastern Nigeria http://journalasrj.com/index.php/ASRJ/article/view/30058 <p><strong>Aim:</strong> To determine the effect of different rates of sawdust (SD) and poultry manure (PM) applied on some soil physical properties of acid sandy Ultisol, and some growth parameters and yield of cocoyam.</p> <p><strong>Study Design: </strong>2 x 5 factorial arrangement in a randomized complete block design replicated three times.&nbsp;</p> <p><strong>Place and Duration of Study:</strong> The experiment was conducted in Eastern farm of Michael Okpara University of Agriculture, Umudike during 2014 and 2015 planting seasons.</p> <p><strong>Methodology:</strong> The treatments comprised of two manure sources at five levels each: sawdust (0, 2, 10, 15 and 20t/ha) and poultry manure (0, 2, 4, 6 and 8t/ha). The treatments were assigned randomly to the plots and incorporated into the soil two weeks before planting. Data were collected on plant height, number of leaves, leaf area, corms, cormels and total yield. Soil samples were collected with core samplers for physical properties such as Soil Bulk density and Total Porosity. All the data collected were subjected to ANOVA for factorial experiment in RCBD at 5% probability level.</p> <p><strong>Results:</strong> The result showed that the interactions of poultry manure and sawdust significantly (p&lt;0.05) improved soil bulk density and total porosity with the lowest value obtained with 0t/ha SD + 8t/ha PM in both 2014 and 2015. The result showed that the interactions of poultry manure and sawdust significantly (p&lt;0.05) increased the leaf area with the highest value obtained with 20t/ha SD + 8t/ha PM in both 2014 and 2015. Also, only the increasing rates of treatment applied significantly (p&lt;0.05) increased the number of leaves, plant height, leaf area and cocoyam yield with the highest value obtained with 20t/ha SD + 8t/ha PM. Also, the various rates of treatment application significantly (p&lt;0.05) increased the cocoyam yield (weight of corms and cormels) with the highest value obtained with 20t/ha SD + 8t/ha PM.</p> <p><strong>Conclusion:</strong> Improvement in growth and yield of cocoyam resulted from the improved nutrient status of the soil as a result of the amendments applied.</p> Iroegbu, Chidinma S, Asawalam, Damian O, O.

The experiments aimed at identifying optimum the rate of the newly introduced NPS fertilizer impact with different levels on growth, yield attributes, yield and economics of sesame in vertisols of Western Tigray at the Humera station, Banat and Kebabo Kafta Humera and Tsegede Wereda’s. The treatments consisted of six levels of NPS 0, 50, 100, 150, 200 and 250 kg ha<sup>-1</sup> and one blanket recommendation N and P was applied. The experiment was laid out in an RCBD with three replications. Yield of Sesame and yield related components showed significant difference (p &lt; 0.001) compared to control. Results showed that number of branches plant<sup>-1</sup>, length of pod bearing zone (cm), plant height (cm), number of capsules plant<sup>-1</sup>, seeds capsule<sup>-1</sup> and seed yield was significant differences at (P&lt; 0.001) Grain yield increases from 444.8 kg ha<sup>-1</sup> to 671.9 kg ha<sup>-1</sup> as NPS and 444.8 kg ha<sup>-1</sup> to 628 kg ha<sup>-1</sup> as NP increases from 0 (control) to 100 kg ha<sup>-1</sup> NPS and 41 kg N and 46 kg P<sub>2</sub>0<sub>5 </sub>ha<sup>-1 </sup>respectively. But NPS was not significant with blanket recommendation of N and P (41 kg N and 46 kg P<sub>2</sub>0<sub>5 </sub>ha<sup>-1</sup>), therefore no need to replace the NP by NPS fertilizer in the study area.</p> Teame Shimgabr, Negasi Gebereslasie, Haile Alene, Welesenbet Haftu, Nebyu Tsegay ##submission.copyrightStatement## http://journalasrj.com/index.php/ASRJ/article/view/30059 Mon, 27 Jan 2020 00:00:00 +0000
