A field experiment (randomized complete blocks with three replicates) was conducted during two successive summer seasons of 2016 and 2017 at Sahl El-Houssinia Agriculture Research Station in El-Shakia Governorate, Egypt. Its lies between 32˚00/00 to 32˚15/00/ N latitude and 30˚50 / 00// to 31˚15 00// E longitude. The combined effect of bio-fertilizers inoculated with Rhizobium radiobacter sp strain (salt tolerant PGPR); Bacillus megatherium (dissolving phosphate) and Bacillus circulans (enhancing potassium availability) and yeast strains (Saccharomyces cerevisiae) combined with different rates of N, P and K fertilizers (50, 75 and 100%) was evaluated on some soil properties, nutrient content in rice plants, and rice productivity in a reclaimed saline soil. From the crop field of the Agricultural Research Institute (ARC), Egypt, 101 grain kernels from rice (Oryza sativa) var. Sakha were selected.   The results indicated that soil pH and EC were decreased in soil treated with bio-fertilizers combined with different rates of mineral fertilizers in comparison with soil treated with yeast and control. Available N, P, K, Fe, Mn and Zn in the soil increased with the use of bio-fertilizers. Application of mineral fertilizers (N, P and K) alone or combined with bio-fertilizers (bacteria and yeast) resulted in increased yield grains and straw of rice plant. Macro- and micronutrients concentrations and uptake in grain and straw of rice plants increased in soil treated with bacteria + 75% N+P+K fertilizers compared with other treatments.

Aims: To evaluate the effect of zeolite and mineral fertilizers on some soil properties, availability of soil nutrients and yield of Jew’s mallow (Corchorus olitorius) in clayey and sandy soils. Study Design: The experimental designed as split plot design with three replicates, the main plots were devoted to zeolite at the rates of 0, 4.76 and 9.52 Mg ha-1 and the sub plots were occupied by mineral fertilizers at the rates of 50% and 100% from the recommended NPK doses. Place and Duration of Study: During spring and summer seasons of 2018, the field experiments were conducted in Sakha Agricultural Research Station Farm (clayey soil) and private farm at Baltium district (sandy soil). Methodology: Jew’s mallow grains (Alexandria variety). Soil samples were collected at (0-30 cm depth) in the initial of experiment and after harvesting with the aid of soil auger at random from different parts of the experimental sites to determine the physicochemical and soil moisture characteristics of the soil. Growth characteristics (plant height and fresh mass weight) were studied. Results: The results showed that ECe, SAR and bulk density values were decreased, while CEC, total porosity, field capacity, permanent wilting point and available water values increased due to application of 9.52 Mg zeolites ha-1 when compared to untreated soil. The maximum stem height and total fresh yield of Jew’s mallow were recorded with the application of 9.52 Mg zeolite ha-1+100% NPK. Conclusion: It could be concluded that the use of zeolite in clayey and sandy soils improved the soil properties, improved the availability of soil nutrients and consequently decreased the environmental pollution. Also, the obtained results are promising for enhancing the horizontal and/or vertical expansion of agriculture in such problematic soils.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

High quantities of mineral fertilizers (MF) are required for good coconut seedling production, whose up dated recommendation is 232 grams per seedling. The objective of this work was to assess the substitution of the MF by organic fertilizer as sugar-cane filter cake (SCFC) on coconut seedlings in polybag. The SCFC is an organic residue from sugar-cane manufacturing composed of various chemical elements, as for instance: nitrogen, phosphorus, potassium, calcium and magnesium. The experiment was carried out at the Itapirema Research Station, Goiana, Pernambuco State, Brazil, in a randomized complete block design, with factorial disposition 52, replicated three times, with six tall coconut seedlings per plot. The treatments were the combinations of five doses of MF (in g seedling-1): 46.25; 92.50; 138.75; 185.00 and control, using urea, simple superphosphate and potassium chloride at the proportion of 1:2:3, respectively, and five doses of SCFC (in kg polybag-1): 0.5; 1.0; 1.5; 2.0 and control. Eight months after young coconut seedlings replacement to the polybags the following parameters were measured: collar girth (CG), leaf area (LA), number of live leaves (NL) and plant height (PH). For leaf nutritional diagnosis and growing media chemical and physical analyses, samples were collected. There was significance for the two factors, individually, to all parameters. The trend analysis revealed linear, quadratic and cubic responses, according to the studied character. The mixture of 0.5 kg of SCFC polybag-1 plus 46.25 g of the MF was sufficient for obtaining seedlings of excellent quality and promoting a fertilizers economy around 80%. According to other results from this research, the number of seedlings per plot and the critical level of nutrients in the leaf of coconut seedlings should be reviewed.

Aims: Two field experiments have been carried out to study the effect of different irrigation periods in the presence of compost as an organic amendment on the yield and quality of lupine (Lupinus termis L.) under the sandy soil conditions. Study Design: Split-plot design.  Place and Duration of Study: The successive winter seasons of 2016/2017 and 2017/2018 at the Ismailia Agricultural Research Station, (30°35'30" N 32°14'50" E elevation 3 m), Agricultural Research Center (ARC), Egypt. Methodology: Compost has been applied at the rates of 11.90, 23.81 and 35.71 ton/ha before planting. Three irrigation intervals were assigned after planting by 3, 6, and 9 days; the applied water volume for each was 4761.91 m3/ha. Results: After harvesting, some parameters were estimated. As the compost rates increased, the soil EC significantly decreased while the available N, P, K, and Fe were significantly increased by 9.51, 12.79, 5.17, and 5.8%, respectively. For same compost rate, the irrigation intervals (3, 6, and 9 days) significantly decreased the available N relatively by 2.88, 5.16, and 6.96%, respectively and the available K by 3.45, 5.06, and 4.37%, respectively. The 6 days interval showed that most significant increase in the seeds' content of nutrients at different compost rates and the seed yield has increased by 19.59, 22.31, and 21.88% for the compost rates of 11.90, 23.81, and 35.71 ton/ha, respectively. The relative increase was by 20.48, 7.63, 4.49, 10.89, and 14.92% for the crude protein, crude lipids, total ash, TSS and the amino acids, respectively. The effect of treatments on the relative shoot moisture (%) and the field water use efficiency (F.W.U.E.) (kg/m3) was discussed. Conclusion: The 6 days irrigation interval along with a compost application rate of 23.81 ton/ha can be recommended for lupine grown in sandy soil as they showed the most significant increase in the nutrients content of seeds by 22.31%.

Ginger is rich in different chemical compounds such as phenolic compounds, terpenes, polysaccharides, lipids, organic acids, minerals, and vitamins. The present study investigated the effect of mineral fertilizers on the content of mineral elements in the rhizomes of Zingiber officinale Roscoe, soil enzymes activity, and soil properties in Surkhandarya Region, Uzbekistan. To the best of our knowledge, the present study is the first in Uzbekistan to investigate the mineral elements of ginger rhizome inhabiting Termez district, Surkhandarya region. A Field experiment was conducted at the Surkhandarya experimental station research Institute. Four treatments have been studied (Control with no fertilizers (T-1), N75P50K50 kg/ha (T-2), N125P100K100 kg/ha (T-3) and N100P75K75 + B3Zn6Fe6 kg/ha (T-4)). Results showed that T-4 treatment significantly increased ginger rhizome K, Ca, P, Mg, Fe, Na, Mn, Zn, Si, Li, and V content as compared to all other treatments and control. T-3 treatment significantly increased Mo, Ga, and Ag content in comparison to other treatments. Soil enzymes showed a significant increase for all treatments against control, while T-4 treatment has recorded the highest enzyme activity in comparison to all other treatments in urease, invertase, and catalase content. Soil chemical properties have significantly changed for all treatments against the non-cultivated soil and the zero fertilizers plantation with variation among different treatments. Results showed that ginger root is rich in minerals and can be used as a great potential for nutritional supplements and soil enrichment. This study suggest that combination of macro-microelements have the potential to increase the content of mineral elements in the rhizomes of ginger in field conditions.

Sunflower is a crop requiring intensive mineral nutrition, therefore, its cultivation demands reserves of nutrients in the soil, which can be replenished by applying mineral fertilizers. Purpose. Our purpose was to study the effects of fertilizers on the growth, development and yield of sunflower hybrids of different ripeness groups (bred at the Institute of Oil Crops) in the Left-Bank Forest-Steppe of Ukraine. Material and methods. The study was conducted at Poltava State Agricultural Research Station named after N.I. Vavilov in 2019–2020 The study object was processes of the growth and development of sunflower plants and formation of sunflower seeds depending on farming techniques. The study subject was sunflower hybrids Ahronomichnyi, Ahent and Serpanok. The following fertilizers were applied: 1) no fertilizers (control); 2) N32Р32К32; 3) N32Р32К32 + foliar fertilization of plants with urea (10 kg/ha) in the phase of 5–6 pairs of leaves; 4) N32Р32К32 + foliar fertilization of plants with microfertilizer Novalon Foliar (1 kg/ha) in the phase of 2–3 pairs of leaves; 5) N32P32K32 + foliar fertilization of plants with microfertilizer Novalon Foliar (1 kg/ha) in the phase of 5–6 pairs of leaves. Results and discussion. The results show that mineral macro- and microfertilizers contributed to more intensive growth and development of plants. Thus, the tallest plants, the largest leaves and calathidiums, and the highest 1000-seed weight were recorded hybrids Ahronomichnyi, Ahent and Serpanok with basic mineral fertilizers at a dose of N32Р32К32 + foliar fertilization with carbamide (10 kg/ha) or with microfertilizer Novalon Foliar (1 kg/ha). The maximum yields from hybrids Ahronomichnyi, Ahent and Serpanok were achieved with basic mineral fertilizers N32Р32К32 + foliar fertilization with microfertilizer Novalon Foliar (1 kg/ha) – 3.35 t/ha, 3.41 t/ha and 3.15 t/ha respectively. The gain to the control (no fertilizers) was 0.33 t/ha, 0.32 t/ha and 0.22 t/ha, respectively. Fertilization also affected the oil content in seeds. Mineral fertilizers N32Р32К32 decreased the oil content in the hybrid seeds by 1.1–1.7% compared to the ‘no fertilizers’ experiment. However, fertilization of plants during the growing period with urea or microfertilizer Novalon Foliar in combination with basic mineral fertilizers N32Р32К32 significantly increased the oil content in seeds. With the best yields, the highest output of oil from the hybrids was 1,406 kg/ha, 1,446 kg/ha and 1,356 kg/ha, respectively. Conclusions. Our results mainly confirm the results of other studies. Mineral fertilizers and microfertilizers promote more intensive growth and development of plants and increase the yields of sunflower seeds. However, there are some discrepancies in the oil content in seeds. Some researchers reported that mineral fertilization increased the oil content in seeds compared to the control (no fertilizers). We found that application of mineral fertilizers at a dose of N32P32K32 caused a decrease in the oil content in seeds, and only supplementary foliar fertilization with urea or microfertilizers increased this indicator

The influence of graded levels of phosphorus at different fertility gradient on soil properties was studied at Zonal Agricultural Research Station (ZARS), GKVK, UAS, Bengaluru under finger millet-maize cropping system. Five phosphorus fertility gradients viz., P0 (Very low), P1 (Low), P2 (Medium), P3 (High) and P4 (Very high) (< 15, 16-30, 31-45, 46-60 and > 60 kg P2O5 ha-1) were imposed. Results indicated that, availability of N, P, K, S, Mg, Mn, Cu content was higher in very high fertility strip, whereas the exchangeable Ca, DTPA-Fe and Zn were significantly higher in medium P fertility gradient strip. Combined application of manures and fertilizers resulted in relatively higher availability of nutrients as compared to inorganics alone. Further, there was a build-up of P in gradient strips with graded levels of P application.

There were six treatments that were Rhizobium strains- BARI RLc-104, BARI RLc-105, BARI RLc-106, BARI RLc–107, mixed culture of the four strains, and control (no Rhizobium). The experiment was designed in randomized complete block having 4 replications of each treatment.The rhizobial inocula were peat based and used @ 1.5 kg/ha. A basal dose of P @ 22 kg/ha, K @ 42 kg/ha, S @ 20 kg/ha, and @ 5 kg Zn/ha was used for all treatments. The highest nodule number (11.7/plant in 2006 and 10.3/plant in 2007) and dry nodule weight (10.53 mg/plant in 2006 and 9.58 mg/plant in 2007) were found with mixed culture. Mixed culture produced the highest seed yield in 2006 (1.36 t/ha, 37.4% higher over uninoculated control) and in 2007, BARI RLc-104 recorded the highest seed yield (1.23 t/ha, 60.3% higher over uninoculated control). However, all the strains including mixed culture had similar seed yields over the years. DOI: http://dx.doi.org/10.3329/bjar.v39i1.20147 Bangladesh J. Agril. Res. 39(1): 105-112, March 2014

Abstract The investigations conducted at the Podu-Iloaiei Agricultural Research Station, Iaşi County, Romania, have studied the influence of different mineral fertilizers rates on wheat and maize yield and soil agrochemical characteristics. In bean-wheatmaize- sunflower-wheat crop rotation, the mean yield increases, obtained for each kg of a.i. of applied fertilizer, were comprised between 8.3 and 10.1 kg in wheat (N120P80- N160P80) and between 10.8 and 11.0 kg in maize (N150P80-N200P100). Generally, nitrogen use efficiency is low and, to achieve maximum yields, need for high doses of nitrogen which can increase the risk of environmental pollution. The N agronomic efficiencies and physiological efficiencies in wheat and maize declined with the increase of nitrogen rate. Wheat placed in rotation for five years, after sunflower at recommended dose (N160P80), physiological efficiency of nitrogen utilization was 43.4 kg grain per kilogram of nitrogen exported from soil, from fertilizer applied. Mean annual amounts of nutrients exported from soil by wheat in dry (14 yr.) and favourable (11 yr.) years in five year crop rotation have varied according to rates, between 34.5 and 100.7 kg at nitrogen and between 6.5 and 18.4 kg at phosphorus. The long-term use of bean - wheat - maize - sunflower - wheat rotation determined the diminution by 43.4% (2,772 t/ha) in the mean annual losses of eroded soil and by 38.5% (5.61 kg/ha) in nitrogen leakages by erosion, compared with maize continuous cropping.

The experiment planting in Last week of September 2017 at Al-Zafraniya station and Last week of October 2017 at AL- Tuwaitha station. The results show increasing significantly in the yield (1110.11 kg. ha-1), percentage of oil (47.12 %), protein content in seeds (43.1%), carbohydrate (25.7%), nutrient content of seed (K, Ca) in Al-Zafraniya location; compared to Al-Tuwaitha location, yield (352.8 kg. ha-1), percentage of oil (41.1 %), protein content in seeds (41.2%), carbohydrate (26.2%), nutrient content of seed (Na, Ca, Mg, Fe) at fertilization, compared to no-fertilizer. It showed significant differences with nutrient content of soil (Na, Mg, Fe) for Al-Tuwaitha location and nutrient content of soil (K, Ca, Mg, Fe, S, Cu), pH, EC for Al-Zafraniya location at fertilization, compared to no-fertilizer. These results shows that the delay at time of cultivation leads to a decrease in seed yield, oil ratio, and percentage of protein in seeds, also high temperatures at seed filling stage leads decrease in seeds, oil and protein content.
