Soybean is an important crop with nutrition, economic and soil fertility improvement benefits to farmers. However, its production in western Kenya is partly constrained by low soil pH and soil fertility levels. A greenhouse pot study was conducted to evaluate the effects of inorganic fertilizers, farmyard manure and lime application on soil pH, nutrient uptake, growth and nodulation of soybean grown in acidic soils from western Kenya. The experiment was set up in a randomized complete block design with eight treatments: control; NPK; manure; lime; manure+lime; NPK+manure; NPK+lime and manure+lime+NPK. Significant effects of inorganic fertilizers, manure and lime applications were observed on all the variables. Manure, lime and manure+lime treatments increased soil pH by 1.33, 2.19 and 2.28, respectively, above the control treatment. The shoot N was lower under control (1.71-1.81%), NPK (1.85-1.98%) and manure (2.00-2.11%) than under all other treatments. Treatments NPK+lime and manure+lime+NPK recorded higher uptake of P and K nutrients than all other treatments. The control and NPK treatments recorded shorter plants and low leaf area and above-ground biomass compared to other treatments. The NPK+lime and manure+lime+NPK treatments recorded higher plant height and aboveground biomass than other treatments. Lime+manure treatment recorded highest nodule numbers and dry weights per plant. Positive relationships were observed between pH and N, P and K nutrient uptake (R2 ranged between 0.30 and 0.77) and between biomass and N, P and K nutrient uptake (R2 ranged between 0.68 and 0.99). From this study, use of manure and lime could result in improved soil pH for better uptake of nutrients, nodule formation and productivity of soybean in Western Kenya.

Organic And Inorganic Fertilizers

The study was carried out to determine the effect of organic and inorganic fertilizers on tomato yield and soil quality.  The study was performed in a randomized complete block design consisting of 7 treatments with 3 replications in the research farm, Shaikh Zayed University, Khost, Afghanistan. The fertilizers treatments were T1, organic fertilizer (5 t/ha); T2, organic fertilizer (10 t/ha); T3, urea (150 Kg/ha); T4, urea (200 Kg/ha); T5, mixed fertilizers (organic fertilizer 3 t/ha + urea (100 Kg/ha); T6, mixed fertilizers (organic fertilizer 6 t/ha + urea (70 Kg/ha) and T7 a control. Results indicate that applications of inorganic fertilizers with a combination of organic fertilizers increased tomato yield and improves the nutrient status of the soil. T5 showed the highest yield of tomato and followed by T4 treatment, which were 33.1 and 31.7 t/ha respectively. The lower yield were obtained in T7 and T1 treatments. The highest plant heights (205.0 and 199.0 cm) were obtained in T5 and T4 respectively, while the lowest plant heights were obtained in T1 treatment and followed by T7 treatment. Similarly, we found that a combination of both inorganic and organic fertilizers application also is the best strategy to improve soil nutrients, maintain soil fertility. Soil P2O5 and K2O, where the highest amounts were obtained in T5 and followed by T6, which were 26.5, 22.5 and 44.5 and 41.5 mg/L respectively. The control treatment had the lowest amount of P2O5 and K2O. Therefore, this study suggests that an appropriate amount of organic fertilizer with inorganic fertilizer not only increased tomato yield but also improve soil fertility.

Excess use of agrochemicals for intensive cultivation affects crop quality and destroys agro-ecosystems, and eventually creates health hazards. The study aims to investigate the effect of Gliricidia sepium (GS) tree leaf as suitable green manures for supplementing nutrient supply along with nitrogen (N) fertilizer to produce quality tomato and soil fertility improvement. A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh, from November 2016 to March 2017. The experiment was laid out in a randomized complete block design (two factors) with three replications. There were nine treatment combinations with three levels of GS tree leaves (5, 10 and 15 t ha−1) and three doses of N (0, 50 and 100% of the recommended dose of fertilizer). The highest tomato yield was recorded in GS15×N100 treatment combination, which was 41.68% higher compared to the control treatment. Decreasing C: N ratio in increasing dose of GS and N treated plot indicated the quality of tree leaves that ensures faster decomposition and high nutrient release pattern of this species. Increasing rate of soil pH and cation exchange capacity (CEC) in different treatments as compared to initial soil showed soil fertility improvement. Overall, the results indicated that quality tomato could be grown successfully by the application of G. sepium tree leaves along with an appropriate amount of N fertilizer. Ann. Bangladesh Agric.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

Low soil organic matter, low nutrient availability and the higher soil pH (more than 8) are the major problem of agricultural practices in region of Toshka. An incubation trial at October 2019 was conducted to investigate the effect of potassium humate (KH) and micronic sulfur (MS) on some chemical properties of different soils (sandy clay soils, loamy sand and sandy soils). The used amendments (KH and MS) were added to the studied soil at 4 levels of each amendment i.e. 0.0, 0.25, 0.50 and 1.0%. A two way randomized completely block design and provided with three replications. Studied parameters were included soil pH, EC, exchange Na and the content of available - P and K. Results showed that, the MS application at 1% level caused a significant decrease in soil pH values compared with the KH application and control treatment. These reductions were more pronounced in case of soil B (loamy sand). Also, KH application gave an increase on exchange Na and available-K. While MS application was cause an increased in soil EC and available-P in the three soils under study. Moreover, the increases in the percentage of available – K with added of KH were higher than added of MS for soils under study. While the percentages of available-P with added of KH were higher than with added of MS for studied soils. It may be recommended to add KH and MS at a rate of 1% to improve the soil chemical properties. But the effect of application from MS has greater than KH to increase dissolved sodium salts on the form of sodium sulfate, which facilitates disposal during soil drainage.

Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic nitrogen and phosphate fertilizers applied as calcium ammonium nitrate and triple superphosphate respectively, on soil pH, available P, total N, organic carbon and sorghum grain yield, on a smallholder farm in Siaya County, Kenya. The experiment was a randomized complete block design consisting of four treatments i.e., FYM applied at 0 and 4 t ha-1 in a factorial arrangement with inorganic fertilizers applied to provide 0 and 26 kg P ha-1 + 75 kg N ha-1, replicated three times. The study was conducted during the long rains of March to June and short rains September to December, 2017. Farmyard manure was applied only during the long rains season of 2017, while P and N fertilizers were applied in both cropping seasons. Soil sampling was done before treatment applications and at harvest time. Soil analysis revealed that the soil was acidic (pH = 4.9) with low available P (5.3 mg kg-1 and N (0.08%) but moderate amounts of C (2.0%) and Ca (3.4 cmol kg-1). The effect of sole application of FYM on soil P, N and grain yield were lower than those of the inorganic fertilizers. Farmyard manure increased soil pH because of its alkalinity (pH = 7.1) while triple superphosphate reduced it due to release of phosphoric acid into the soil. The mean annual (average of two seasons) grain yield increments, above the control with no nutrient inputs, due to 4.0 t FYM, 26 kg P ha-1 + 75 kg N ha-1 and 4.0 FYM + 26 kg P ha-1 + 75 kg N ha-1 were 64, 191 and 259%, respectively. Therefore combined applications of FYM and N and P fertilizers have the potential to increase sorghum grain yield on Kenyan acid soils.

This study investigated the effects of applying different combinations of two contrasting plant residues, Calliandra calothyrsus (Calliandra) and maize stover, with urea on Striga infestation and maize yield in western Kenya. A randomized complete block design (RCBD) with 12 treatments replicated four times was used. The following plant residue: urea combinations was used so as to supply a total of 75 kg ha-1 in each treatment combination; 75:0, 60:15, 45:30, 30:45, 15:60, and 0:75 for five seasons (2007-2009). A control treatment where no nutrient inputs were applied was included. Calliandra applied at 45 kg N ha-1 plus urea (30 kg N ha-1) and maize stover applied 15 kg N ha-1 plus urea (60 kg N ha-1) had consistently lower Striga infestation compared other treatments. Negative linear relationship between maize yield and Striga population were observed in the first three seasons i.e. 2007 LR, 2007 SR and 2008 LR. Overall mean maize grain yields over the five seasons were highest (3.0 t ha-1) under maize stover (30 kg N ha-1) combined with urea (45 kg N ha-1) followed by Calliandra (45 kg N ha-1) combined with urea (30 kg N ha-1) with (2.7 t ha-1). Maize stover (30 kg N ha-1) in combination with urea (45 kg N ha-1) increased maize grain yields relative to the control by 275%, 107% and 155% in the first, second and third seasons respectively. Treatments with Calliandra (45 kg N ha-1) in combination with urea (30 kg N ha-1) increased maize grain yields relative to the control by 191%, and 233% in the first and third seasons respectively. The control and sole maize stover (75 kg N ha-1) had the lowest yields across all the seasons. The optimum application rate for stover was 30 kg N ha-1 nitrogen equivalent while that for Calliandra was 45 kg N ha-1.

The productivity of land and plants have decreased slowly, due to the use of inorganic fertilizers continuously. Efforts to improve productivity are reducing inorganic fertilizers and returning organic matter to the soil. The aim of this research are (1) to identify the chemical characteristics of biofertilizer with an indigenous microorganism as bioactivators and (2) to study the effect of biofertilizer on nutrient uptake of maize plant. The research was conducted at Laboratory, Greenhouse, and Experimental Field of Politeknik Pertanian Negeri Payakumbuh, West Sumatra Indonesia. The first step experiment in the Laboratory was produced indigenous microorganism from banana humps. The second step of making bio-fertilizers in Greenhouse used a Completely Randomized Design with four treatments of indigenous microorganism (IMO) level 0%, 10%, 20%, 30% in biofertilizer with five replications. The third step of biofertilizer application on the Experimental Field used Randomized Block Design Factorial arranged with two factors and three replications, the first factor IMO level in biofertilizer (M) 0%, 10%, 20%, 30% and the second factor was the dosage of inorganic fertilizer (P) 0%, 50%, 100% of the recommended dosage, 12 combinations of treatments were obtained. Results showed that microbe consortium (Enterobacter cloacae, Bacillus subtilis, Pseudomonas fluorescens, Aspergillus niger, and Trichoderma asperellum) in biofertilizers with different levels would affect the chemical characteristics of biofertilizer. Biofertilizers influences nutrient uptake of P and K maize plant, while inorganic fertilizer influences nutrient uptake of N and P maize plant.

The present investigation was conducted with the objective of utilizing locally available organic resources for substituting chemical fertilizer nitrogen partly and augmenting soil health.  The experiment was carried out for the crop kharif rice (Oryza sativa L.) in coastal Karnataka with eleven treatments laid out in randomized block design with three replications. Vermicompost (VC), Poultry manure (PM) and Fish manure (FM) were used as organic nitrogen sources integrated with mineral nitrogen source of fertilizer urea at substitution ratios of  25, 50 and 100 percent. These treatments were compared with control and recommended dose of nitrogen. The results revealed that the substitution of 50 per cent of nitrogen through VC  recorded significantly (P<0.05) higher plant height  (92.27 cm), higher number of productive tillers (16.85 hill-1), higher grain yield (5434 kg ha-1) and straw yield ( 6817 kg ha-1) compared to control. The results of the soil sample analysis for soil fertility parameters indicated that the major nutrients were significantly (P<0.05) influenced by integrated nitrogen management.  The available nitrogen (382.36 kg ha-1) and available potassium (143.7 kg ha-1) were significantly (P<0.05) higher in the treatment T4 where a recommended dose of nitrogen was substituted by 50 percent VC compared to control (294.05 kg ha-1 and 92.31 kg ha-1 respectively). However, the available soil phosphorus was significantly higher with treatment 50 per cent  RDN substituted by PM  (78.83 kg ha-1) as compared to control (43.93 kg  ha-1).  Thus, integrated resource management improved crop yield and post-harvest soil fertility.

A field experiment was conducted during rabi season (2014-16) at Research Farm, R.B.S. College, Bichpuri, Agra (U.P.) to study the effect of nitrogen and FYM levels on growth, yield and uptake of nutrients in oat (Avena sativa L.) and soil fertility. The experiment was laid out in randomized block design with four levels of nitrogen (0,50,100 and 150 kg ha-1) and three levels of FYM (0, 5 and 10 t ha-1) with three replications. The results revealed that the plant height, yields of oat crop increased significantly up to 150 kg N and 10 t FYM ha-1 over control. The maximum values of green foliage (447.16 and 414,03 qha-1) and dry matter yield (64.98 and 60.30 q ha-1) were recorded with 150 kg N and 10 t FYM ha-1 , respectively. The application of FYM alone was also found to be more beneficial in terms of growth and yield of oat crop over control. The interaction effect between 150 kg N ha-1 and 10 t FYM ha-1 recorded maximum yield than other treatment combination. The maximum content (14.14 and 14.10 %) and yield of protein in oat crop (920.6 and 853.5 kg ha-1) were recorded with 150 kg N and 10 t FYM ha-1 but maximum value of crude fiber (32.96 and 33.7 %) were recorded under control, respectively. However, crude fiber content in oat was not affected significantly with N and FYM levels. The uptake of major (N,P and K) and micronutrients (Fe,Mn,Cu and Zn) by oat crop increased significantly with the levels of nitrogen up to 150 kg ha-1 and FYM 10 t ha-1, respectively. The status of organic carbon and available nutrients in post harvest soil improved with 150 kg N and 10 t FYM ha-1.The minimum amounts of available nutrients in post harvest soil were recorded under control treatment.
