In the savanna soil of Nigeria, micronutrient deficiency was not noticed in the past but with the intensification of agriculture over the years, crop exploitation of soil available nutrients, crop removal and adverse cultural practices of farmers have led to the incidence of micronutrient deficiency with negative effect on growth, yield and quality of crops. To enhance micronutrient availability, use and use efficiency to crops, a field experiment was set up on sorghum at Samaru in the Northern Guinea Savanna of Nigeria with foliar Algifol (Alg) nutrients solution and NPK. The objectives of the studies were: To test the effectiveness of the nutrient solution and NPK on growth and yield of sorghum in the Nigeria savanna and to determine optimum rates of application of the nutrient solution on sorghum under a tropical condition. The treatments were four levels each for the nutrient solution, NPK and a combination of both as ½Alg, 1Alg, 1½Alg and 2Alg at the rate of [5:10:15:20ml) of the concentrated solution to 10 litres of water per hectare and 64:32:30 kgha-1 N, P2O5 and K2O being therecommendation for sorghum in the Northern Guinea Savanna. Data were collected on plant height, plant girth, panicle yield, grain yield and stover. The treatments were laid in a Randomized Complete Block Design (RCBD) with three replications. The results showed that plant height and girth were highly significant (P < 0.01) at 9 weeks after planting (WAP) and as well as stover. Head and grain yield were positively and highly significantly correlated (r = 0.69** and 0.62**) with dry matter yield (DMY) indicating a positive relationship amongst the plant parameters in response to treatments. Co-application of the nutrient solution with NPK had greater nutritional efficiency on sorghum in the savanna than their sole application since the nutrient solution is deficient in major plant nutrients.Keywords: Nutrient solution, northern guinea, complementary application and tropical environment.

Soybean genotypes grown in sub-tropical climate may exhibit lodging. The plant lodging is influenced by soil type and fertility level, sowing date, latitude and altitude of the location, plant population and conditions of crop development. Plant regulators and herbicides are able to avoid or reduce plant lodging. This study aimed to verify the effects of the growth regulators TIBA and daminozide on vegetative growth and yield of soybean cultivar CD 214 RR. The experiment was carried out at a field in randomized block design with four replications in a factorial scheme. The A factor was represented by the combination of regulators TIBA and daminozide and its concentrations, and the Factor B was seven times of evaluation of injury and plant height or eight times of evaluation of lodging. In the range of doses used, the application of daminozide resulted in greater injury to soybean plants than TIBA. The smaller plant height was achieved by the application of 6 g ha-1 of TIBA and 1200 g ha-¹ of daminozide. Treatments with daminozide (100 g ha-¹) and TIBA (10 g ha-1) stood out due to the reduced lodging of soybean plants. Grain weight increased linearly when the levels of TIBA increased. There was a negative correlation between lodging and grain yield and a positive correlation between plant height and lodging. There was also a negative correlation between injury caused by the application of plant regulators and lodging.

AbstractA field experiment was carried out to study the effect of spacing and nitrogen level on growth and yield of maize in Parbat from February to July, 2019. The experiment was laid out in two Factorial Randomized complete Block Design (RCBD) comprising of spacing: 60×15 cm and 60×25 cm and nitrogen: 30, 60, 90 and 120 kg/ha level as treatment with three replications. “Arun-2” variety of maize was planted on clay loam and acidic soil (pH 5.3) having medium in total nitrogen (0.15%), medium in soil available phosphorus (48.1 kg/ha), medium in soil available potassium (218.8 kg/ha) and medium in organic matter content (2.92%). Result shows that yield was significantly increased with increment in N-level up to 90 kg N/ha. The grain yield (5.18 mt/ha) was significantly higher at 90 kg N/ha than at 30 and 60 kg N/ha but at par with 120 kg N/ha. Significant effect on grain yield due to spacing was observed. The grain yield (4.11 mt/ha) obtained at spacing 60×15 cm. Moreover, the highest grain yield showed that highest grain yield (4.33 mt/ha) was obtained under 90 kg N/ha plus 60×15 cm spacing. The result revealed that different spacing and nitrogen level significantly affect the plant height and leaf area index. The plant height and leaf area index were significantly high at close spacing (60×15 cm) and at 120 kg N/ha. Likewise, yield attributing characteristics like cob length, cob diameter, number of kernel/rows, number of kernel row, thousand gran weight were the highest at 90 kg/ha but as par with 120 kg/ha at close spacing (60×15 cm). This study suggested that maize production can be maximized by cultivating “Arun-2” maize fertilizing with 90 kg N/ha and maintaining 60×15 cm spacing.

Lettuce (Lactuca sativa L.) is one of the vegetables that are commonly cultivated by using hydroponic systems. Some hydroponic systems require high current expenses in particular for the electricity in order to circulate nutrient solution e.g. in the water culture system – deep flow technique (DFT) -. Electricity costs can be reduced by changing from continuous nutrient flow to intermittent nutrient flow. The aim of this research was to investigate the effect of interval nutrient flow on growth and yield of lettuce. The experiment was conducted in Cirebon from February to April 2018. The experiment was arranged by using randomized complete block design with four treatments: (i) continuous nutrient flow (control), intermittent nutrient flow (nutrient flow during (ii) 15 minutes, (iii) 30 minutes, and (iv) 45 minutes). For each intermittent treatment, the nutrient flow was interrupted for 60 minutes. Each treatment was repeated four times. The result showed nutrient flow interval affected to plant height, shoot diameter, and leaf area at 35 days after planting (DAP). Meanwhile, leaves number, root volume, and fresh weight of harvested crops were not significantly different in all nutrient interval treatments. The highest plant height and shoot diameter were detected in the treatment (ii) nutrient flow during 15 minutes and interruption for 60 minutes, the results were not significantly different to the control – continuous flow treatment. It can be concluded the interval nutrient flow can be used as an alternative of the continuous flow of nutrient solution in hydroponically DFT.

Fertilizers and fertilization technology have important roles in increasing crop production including lowland rice. In response to the issue, a field experiment was conducted to study the effects of micronutrients on growth and yield of lowland rice. The experiment was carried out at Cihideung Ilir Village, Dermaga Sub-district, Bogor Regency from November 2015 until March 2016. The experiment consisted of 8 treatments, namely control (without fertilization), NPK-standard, NPK-standard  + ¼ dosage of Hortigro Rice fertilizer, and ¾ NPK  + ¼  until 11/4 dosages of Hortigro Rice fertilizer as a source of macronutrients N, P, K and micronutrients of Mn, Cu, Zn, B, and Mo. The treatments were arranged in a Randomized Block Design with 3 replications. Parameters observed during the research were plant height, tiller number, and yield of grain and straw of INPARI-32 lowland rice as crop indicator. The  results  showed that among other treatments, the highest plant height was resulted from the application of ¾ NPK-standard + ¼ Hortigro Rice, i.e. around 124 cm at 60 days after planting. The highest harvesting dry weight of grain and straw were observed in NPK-standard + 1/4 of Hortigro Rice fertilizer treatment, i.e. around 9.0 Mg ha-1 and 25.9 Mg ha-1, respectively. This yield showed a significant difference with ¾ NPK-standard combined with ¾  -11/4 dosages of Hortigro Rice. The highest  dry weight of  milled grains was  resulted in the application of  ¾ NPK-standard + 1/2 Hortigro Rice, i.e. around 7.3 Mg ha-1, which is significantly different from that in ¾ NPK-standard combined with 1.0 - 11/4 dosages of Hortigro Rice treatments, while the highest dry weight of straw was provided by NPK-standard, i.e. around 14.0 Mg ha-1. The highest  dry weight of 1000 milled grains and ratio of  dry weight of milled grain to straw were provided by ¾ NPK-standard + 1/2 Hortigro Rice around 32.0 gram and  0.63, respectively. The results indicated that the application of micronutrient fertilizer of Hortigro Rice in combination with NPK fertilizers can potentially increase lowland rice productivity due to the micronutrients content of Mn, Cu, Zn, B, and Mo in it.

A study was conducted to determine the effects of compost tea application on the soil properties, growth and yield of amaranthus (Amaranthus caudatus L) in Wukari, Northern Guinea Savanna, Nigeria. The experimental variables include compost tea of 10 liters water/1 kg compost, compost tea of 20 liters water/1 kg compost, and compost tea of 30 liters waters/1 kg compost, 120 kgN/ha of urea fertilizer and no treatment. The treatment combinations were done in a randomized complete block design (RCBD), replicated trice on a land area of about 150m2 (0.015 ha) consisting of 15 plots measuring 4 m by 2 m each. The prepared compost tea had the chemical constituent in adequate quantities except for total nitrogen and the micronutrients determined. Compost tea had significant effect on most of the parameters considered. Application of the extract resulted to increase in total nitrogen, organic carbon, exchangeable magnesium and exchangeable sodium. The growth parameters; plant height and stem girth increased significantly with the application of 2.5 t/ha of compost soaked in 10 liters of waters which gave the highest yield of Amaranthus caudatus when weighed. Although the compost tea extract was effective to some extent, fortification with organic additives that will add the missing micronutrient and inorganic additives is recommended.

Many have reported that application of Silicon (Si) can alleviate environmental stress and increase grain yield of maize plants under stresses. This study aimed to examine the effects of adding organic or silicate fertilizer on several varieties of maize in rainfed area during a dry season, by conducting field experiment designed with Randomized Complete Block Design testing two treatment factors, i.e. maize varieties (V1= Bisi-2, V2= Srikandi, V3= Pioneer-27) and fertilizer combinations (F1= NPK only, F2= NPK+organic, F3= NPK+silicate). Results indicated that there were significant effects of fertilizer combinations and varieties on growth and yield of several maize varieties, in which the mean values were highest in maize plants fertilized with NPK+silicate fertilizers, except harvest index. Among the varieties, Pioneer-27 (hybrid) yielded the highest followed by Srikandi (open-pollinated) and Bisi-2 (hybrid) yielded the lowest grain weight per plant. However, there were interaction effects of the treatment factors, meaning that there were different responses between varieties of maize to application of organic or silicate fertilizer in addition to NPK fertilizer in terms of plant height, AGR (average growth rate) of plant height and dry grain yield per plant. Grain yield per plant of Pioneer-27 could be increased with application of organic (150.79 g/plant) or silicate (189.43 g/plant) compared with NPK only (133.99 g/plant), while that of Srikandi and Bisi-2 could only be increased by addition of silicate (113.83 g/plant in Srikandi and 103 g/plant in Bisi-2) compared with NPK only (93.77 g/plant in Srikandi and 82.59 g/plant in Bisi-2).

ABSTRACT The aim of this study was to evaluate the effect of thermally dried sewage sludge on soil fertility, growth and yield of sunflower. The experiment was conducted in a Nitosol area of the Institute of Agricultural Sciences of the Federal University of Minas Gerais, in Montes Claros-MG, Brazil. The treatments consisted of four doses of sewage sludge (0, 10, 20 or 30 t ha-1, dry weight basis), with six replicates in a randomized block design. The levels of nutrients in soil and plant, soil fertility indices, stem diameter, plant height, head diameter and grain yield were evaluated. Stem diameter, plant height, head diameter and grain yield increased with increasing doses of sewage sludge. The application of the residue increased linearly the contents of soil organic matter and N in sunflower leaves. On the other hand, pH, the exchangeable bases, total and effective cation exchange capacity, base saturation, H+Al, Al, soil contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B, and the leaf contents of P, K, Ca, Mg, S, Zn, Cu, Mn, Fe and B were not influenced by the application of sewage sludge doses of up to 30 t ha-1.
