Phosphor is a macro nutrients and it becomes the main limiting factor for maize growth on Ultisols. Rock phosphate is one of P fertilizer sources contains high P and Ca content, slow release and soluble under acid condition, suitable for acid soil. The objective of this research is to study the solubility of rock phosphate and its influence to the growth and yield of maize on Ultisols.  This research was conducted in the research laboratory and the green house of Indonesia Soil Research Institute (ISRI). Ultisols soil samples were taken from oil palm plantation in North Sumatera. Christmas Island Rock Phosphate (CIRP) and Tunisia rock phosphate was used in this research. There are two activity conducted simultaneously, which is application of rock phosphate on Ultisols under plant indicator and without plant. The experimental design is randomized complete block design with 5 treatments and 3 replications. The pot experiment without plant was conducted using1 kg of soil sample mixed with rock phosphate treatment and placed into plastic plot.  During 3 months of incubation, soil water content was maintained under field capacity by aquadest.  The dosages of P fertilizer were 0, 157.6 and 315.2 kg P2O5 ha-1. Soil samples were taken on 1, 2, and 3 months after P fertilization for measuring pH, P content (by HCl 25 %, Bray 1 and Olsen extraction), P-inorganic fractionation (Al-P, Fe-P, Rs-P and Ca-P), exchangeable acidity (Al and H), Al and free of Fe oxide. The pot experiments with maize were conducted using 7.5 kg soil samples mixed with 2 different rock phosphates as a treatment. The dosages of rock phosphate were similar with experiment 1. Urea 300 kg and 150 kg KCl ha1 were applied as a basal fertilizer. Maize was planted two seed per pot and maintain until harvest time. The result of the research shows that soil P content increase with RP application, Tunisia rock phosphate give higher response than the CIRP. Direct application of rock phosphate with Fe and Al content did not increase significantly the Aldd, Al2O3 and Fe2O3 content on soil.  Application of CIRP and Tunisia rock phosphate increased maize growth and yield significantly.

Liming of six acid soil samples in an incubation experiment with rates to raise the soil pH to 6.0 or above eliminated Al soluble in 0.01 M CaCl2, reduced soluble Mn and Zn, increased NO3-N markedly, and at the highest pH increased the amounts of NaHCO3-soluble P in some of the soils. In corresponding pot experiments, liming increased the yield of alfalfa and in three of the soils the yield of barley also. Liming reduced the concentrations of the metals in the plants and at the highest pH tended to increase the P content of the plants. Liming to a pH of about 5.3 eliminated or greatly reduced soluble Al and the soils were base saturated as measured by the replacement of Al, Ca, and Mg by a neutral salt. There was some evidence that liming to reduce soluble Al and possibly Mn was beneficial for plant growth. Gypsum increased the concentrations of Al, Mn, and Zn in 0.01 M CaCl2 extracts of the soils whereas phosphate reduced them. The changes in the Mn content of the plants following these treatments were in agreement with the amounts of Mn in the CaCl2 extracts.

Purpose: To evaluate the blended fertilizer formulas types, under unlimed limed condition of Asossa acid soil on soybean in Benishagul Gumuz of Ethiopia. Methods: Two factorial RCB design with three replications was used in the investigation. Five types of blended fertilizer formulas were tested under limed and unlimed condition in Factorial Randomized Complete Block Design. Lime and blended fertilizer types were used as factor. The amount of lime that was applied at each location was calculated on the basis of the exchangeable acidity, bulk density and 15 cm depth of the soil. One mole of exchangeable acidity would be neutralized by an equivalent mole of CaCO3. Accordingly, the amount of lime for this particular activity would be uniformly applied for all plots at 1.5 times of the exchangeable acidity (Equation 1) and incorporated in to the soil a month before seed sowing. Results: The effects of applied lime (CaCO3) and fertilizer types on growth and yield components of soybean were non-significantly (P>0.05) influenced except 100 seed weight, whereas the lime by blended fertilizer types interaction effects were not-significantly (P>0.05) affect all growth and yield components of soybean (Table 2). The highest plant height (71.58 cm) was obtained from NPKSZnB (Formula 5 modified) fertilizer type, however statistically non-significant from the other treatments. Conclusion: The partial budget analysis indicated that, it was not necessarily based on the highest marginal rate of return, rather based on the minimum acceptable marginal rate of return and the treatment with the high net benefit, relatively low variable cost together with an acceptable MRR becomes the tentative recommendation. Therefore we recommend the treatments (100 kg /ha NPSB) that have acceptable marginal rate of return, relatively high net benefit and relatively small total cost of production for soybean production in Asossa zone.

A field experiment was conducted at the field laboratory of Department of Crop Botany and Tea Production Technology, Sylhet Agricultural University from August 2016 to January 2017 to select the best suited okra genotype(s) considering growth and yield performance among eleven genotypes viz. BARI Dherosh−1 (control) and 10 exotic (Japanese okra) cultivable in acidic soil conditions. All okra genotypes were evaluated in relation to morphological characteristics and yield performance at defined area of study. The treatment combinations were laid out in a Randomized Complete Block Design (RCBD) with three replications. In almost all parameters, significant variations were observed. Experimental findings revealed that BARI Dherosh−1, JO−2, JO−6 and JO−10 showed excellent performance in germination capacity. The high yielding genotype BARI Dherosh−1 exhibited taller plant at final harvest. Early flowers, individual fruit weight with maximum number of flowers and fruits plant-1 was observed in JO−6. The genotype JO−3 produced the highest number of branches, internodes and leaves at final harvest. The flowering duration was long in the genotype JO−2. The highest fruit setting (%) was observed in JO−1. The longest fruit length and the lowest number of aborted fruits were observed in JO−5 whereas BARI Dherosh−1 showed the largest fruit diameter at 9 DAF and heaviest hundred seed weight. The highest fruit fresh weight observed in JO−4 and the highest fruit dry weight observed in JO−5 at 9 DAF.  Regarding fruit yield, the genotype JO−6, JO−10 and JO−3 performed better. The genotypes JO−6 and JO−10 were found to be promising genotypes in acid soil considering the morphological features and yield attributes. Since the variety of our research is suitable for Sylhet region acid soil, if our variety is combined with Sylhet’s cropping pattern cropping intensity will be increase, which will benefit the farmer financially and meet the nutritional needs.

Purpose: The aim of the study was to assess the effects of groundnut shell incorporation rates on the growth and yield of maize. Research methods: The study was carried out at the students’ demonstration farm of the Federal Polytechnic, Mubi, Adamawa State, in 2018. Seeds were sown on a prepared land treated with four (4) doses of groundnut shells (0, 25, 50 and 75 tons/ha) arranged in a randomized complete block design (RCBD), replicated 4 times. Each plot was marked out at 2.0 m length × 2.0 m width with 0.5 m gap between the replicated plots and blocks. Maize growth parameters were determined at 2, 4, 6 and 8 weeks after sowing and maize yield parameters were determined at 10 and 12 weeks after sowing (WAS). Findings: The groundnut shell application rates increased maize growth parameters such as, plant height, number of leaves per plant, leave area index, and stem girth, number of cobs per plant and cobs weight. The results revealed that plant height, number of leaves, leaf area index and stem girth were significantly (P≤ 0.05) influenced by the treatments, except for the control treatment at 2- WAS. The higher application rates (50 and 75 t/ha) of groundnut shell significantly (P≤ 0.05) influenced the plant growth components better than the 25 and 0 t/ha treatment rates. Research limitations: There were no limitations to report. Originality/Value: The results suggests that groundnut shell incorporation rate at 50 t/ha could be recommended as the most appropriate and profitable for high performance of maize plants in Mubi. The results generally suggest that maize plants may tolerate even higher rates of groundnut shell incorporation beyond the rates used in the study.

Integrated Nutrient Management (INM) is a novel strategy to achieve sustainable crop production in degraded soils through judicious and balanced plant nutrients utilization. Sole application of chemical fertilizers in crop production causes soil and environmental pollution. The present study was designed to assess the effects of application of organic manures conjointly with chemical fertilizers on growth and yield of okra in acid soil. The experiment was consisted of four treatments viz. T0 [Control], T1 [Recommended dose of chemical fertilizers (RDF)], T2 [Dolomite (D) @ 1t ha-1 + RDF], T3 [Poultry manure (PM) @ 3t ha-1 + RDF], T3 [Cow dung (CD) @ 5t ha-1 + RDF] with six replications in a randomized complete block design. The results indicated that the use of PM with RDF showed better performance in the growth and yield attributes of okra. Compared with others plots, the highest plant height (114.10 cm), fresh weight plant-1 (591.58 g) and dry weight plant-1 (86.73 g) were observed in the PM-treated plot. Similarly, the highest number of fruits plant-1 (20.33) and fruit yield (13.58 t ha-1) were also found in PM-treated plants. Therefore, under acidic soil conditions, organic and inorganic fertilization may have a significant positive impact on the growth and yield of Okra.

Biochar as agricultural soil amendment to improve soil physico-chemical properties, crop productivity and sustainable soil fertility management is a well-known practice. A field experiment was conducted to evaluate the effect of biochar on growth and yield components of carrot and selected soil physic-chemical properties. The study was carried by employing a randomized complete block design with factorial arrangement of four level of biochar (0, 4, 8 and 12 tons ha-1) and four level of Nitrogen/Phosphorus (N/P) fertilizer rate (0/0, 60/10, 90/15 and 120/20 kg ha-1) with four replications. Biochar significantly influenced physico-chemical properties of soils, such as bulk density, total porosity, pH, EC, SOC, TN, Av. P and CEC respectively, as compared to control. The results revealed substantial responses to biochar and N/P fertilization on growth and yield components of carrot with increasing level of biochar and N/P fertilizer rate. None of the others yield parameters were significantly affected by the interaction of two factors. From the present study, it can be concluded that dung cake biochar should be applied to enhance and improve soil physical and chemical properties for favourable plant growth.
