Foliar Fertilizer

Recently, there has been a growing interest in supplementing plant nutrition with foliar fertilizers. Foliar application of nutrients is considered a promising environmentally friendly strategy for improving the yield and nutrient efficiency of crops. Little work with foliar appliances on perennial fruits bushes, blackcurrant (Ribes nigrum L.), respectively, has been reported. This study was conducted to evaluate the growth and yield response of three blackcurrant varieties to macro and micronutrients’ foliar fertilizer solutions. Principal component analysis and factors environmental fitting were performed for the global assessment of growth and increases in branches length responsible for yield production throughout the entire vegetation period and reported to the final development. The results endorsed the benefits of foliar fertilization. Each variety has a preference for a specific foliar treatment. The highest increases in branches length for Ruben variety was with Ascovigor foliar fertilizer; for Tiben with Kombimax; for Tines with Mikromix. The varieties growth dynamics due to fertilizers was best fitted to foliar Kombimax. Stable models were found to all blackcurrant varieties depending on developmental stage and foliar fertilization application. Application of foliar fertilizer is very profitable in terms of pairing each variety with optimum product, which will increase its specific yield potential.

The experiment was conducted to determine the growth and yield response of pak choi (Brasiccarapa var. Chinkang Genghis Khan) to different foliar fertilizers (viz. vermitea, commercial foliar fertilizer, effective microorganisms [EM-1] and natural farming inputs [NFI]) under protected cultivation. It aimed to evaluate the influence of the different foliar fertilizers on pak choi in terms of growth characteristics, yield components, and pests and disease incidence. Similarly, to conclude which among the foliar fertilizers evaluated will be most the economical for pak choi production. The study was done in the DA-ATI IV-A and LSPU Organic Agriculture Learning Site in the Laguna State Polytechnic University, Siniloan, Laguna in December 2015 to February 2016. A total of 300 plants were used as experimental units in the study. Every treatment was replicated three times and each replication has 10 polyethylene bags planted with two plants each. Data was collected and analysed with the use of the Duncans Multiple Range Test (DMRT). Results revealed that the foliar fertilizers used have no remarkable effect on the weekly height, weekly growth rate, length of leaves, and shoot root ratio of pak choi. Nevertheless, commercial fertilizer significantly increased the mean number of leaves (7.53cm), width of leaves (15.10cm), economic and biological yields (105.10 grams and 106.88 grams, respectively) of pak choi compared with the rest of the treatments, except for vermitea which produced a comparable width of leaves (15.04cm). Also, a significantly lower number of the damaged leaves caused by looper (TrichoplusianiHübner) was noted on plants treated with commercial foliar fertilizer (0.51 leaf per plant). The highest net income was obtained by commercial foliar fertilizer-treated plants, but plants treated with vermitea earned the highest return of investment (ROI). Therefore, the utilization of vermitea in pak choi production can reduce the cost of fertilizer and contribute to an economical production system under protected cultivation.

Zinc Fertilizer

Actual yields of maize harvested by farmers are at level much below attainable yield potential of currently cultivated varieties. Among many growth factors zinc was recognized as one of main limiting factors of maize crop growth and yielding. This hypothesis has been verified within a three-year field study, where zinc fertilizer was applied to maize plants at the 5<sup>th</sup> leaf stage. Maize crop responded significantly to zinc foliar application in two of three years of study. The optimal rate of zinc foliar spray for achieving significant grain yield response was in the range from 1.0 to 1.5 kg Zn/ha. Grain yield increase was circa 18% (mean of three years) as compared to the treatment fertilized only with NPK. Plants fertilized with 1.0 kg Zn/ha significantly increased both total N uptake and grain yield. Yield forming effect of zinc fertilizer revealed via improvement of yield structure elements. The number of kernels per plant showed the highest response (+17.8% as compared to the NPK plot) and simultaneously the highest dependence on N uptake (<i>R</i><sup>2</sup> = 0.79). For this particular zinc treatment, however, the length of cob can also be applied as a component of yield structure significantly shaping the final grain yield.

The use of chemical fertilizers to improve soil fertility, and hence, crop yield, have been reported to have adverse effects on agricultural products, man and his environment, hence, this research looked into the growth and yield response of foliar application with Moringa oleifera leaf extract on Okro. Different concentrations of Moringa leaf extracts at the rate of 5ml, 15ml and 25ml was assessed on the growth and yield of Okro using topsoil as the growing medium. The experiment was laid out in a randomized complete block design with three replicates. Growth and yield parameters were collected on plant height, number of leaves per plant, number of fruits per plant, and length of fruit per plant. Parameters measured were subjected to Analysis of Variance (ANOVA) for Completely Randomized Design (CRD) and means were separated using Duncan’s Multiple Range Test (DMRT) at 5% probability level. The results showed that the treatment with 25ml concentration has a more significant effect than others on Okro. Therefore, treatment with 25ml performed better than the other two treatments in the study area. Hence, this study recommends the foliar application of Moringa extract to farmers for improved yield and production of Okro.

Beneficial Effects

AbstractRhizobial lipochitooligosacharides (Nod factors) influence the development of legume roots, including growth stimulation, nodule induction and root hair curling. However, their effect on the green parts of plants is less known, therefore we evaluated seed and foliar application of an extract containing Nod factors on pea growth and yield. Pea plants were examined from emergence to full maturity, including growth dynamics and morphological (nodule number and weight, the quantity and surface area of leaves) or physiological (photosynthesis and transpiration intensity, chlorophyll and nitrogen content) parameters. The foliar application Nod factor extract, or seed dressing followed by foliar application, resulted in the best outcomes. The number and weight of root nodules, the chlorophyll content in leaves, and the intensity of net photosynthesis were all elevated. As a consequence of Nod factor treatment, the dynamics of dry mass accumulation of pea organs were improved and the pod number was increased. A significant increase in pea yield was observed after Nod factor application. Increase of nodule and pod numbers and improved growth of roots appear to be amongst the beneficial effects of Nod factor extract on the activation of secondary plant meristems.

Partial Explanation

Wheat crops in southern Queensland grown on two different clay soils were studied in terms of growth, development, water economy, and uptake of nitrogen and phosphorus in a season when growing season rainfall was only 50 mm. No significant grain yield response to either nitrogen or phosphorus was detected, although growth response in the vegetative phase was apparent. Mean grain yields on the two soils were 254 and 277 g m-2. These are underestimates of yield potential because of losses due to a mouse plague. Mean yield inside metal mouse exclosures was 303 g m-2. On the higher-yielding site the water use determined from augered soil samples was 192 mm, comprising 50 mm of rain during the 139 days of crop growth and 142 mm of soil water conserved during the preceding summer. The pattern of water extraction was sequential removal of the stored water, starting from the soil surface and extending to a depth below 90 cm. Soil water potential after flowering reached well below - 15 bars. The water use efficiency for grain production was 1.58 g m-2 mm-1 of evapotranspiration, which is higher than most other reports for wheat crops found in the literature. A partial explanation for this high value is that most of the soil water (est. 86%) was transpired by the crop with only a minor proportion (14 %) lost by bare soil evaporation. In addition, the crop appeared to become progressively more adapted to water stress from early in the life cycle, and this stress resulted in slow extraction of subsoil water held at low potentials and therefore in conservation of soil water until the grain-filling phase. The results are discussed by comparing them with those of a crop grown mostly on current rainfall.

Fruit Crop

Pineapple [Ananas comosus (L.) Mere] is an important fruit crop cultivated in many tropical countries. This fruit crop requires large amounts of nitrogen (N) and potassium (K) to maximize yield. Although pineapple has low water requirements, extended drought can affect yield. Two experiments were conducted to study the effects of fertilizer application methods and drip irrigation management on pineapple yields. Pineapple cultivars MD-2 and Cabezona were planted at Isabela and Lajas, Puerto Rico, respectively. Fertilizer and irrigation treatments included: i) Controlapplication of 896 kg/ha of a granular fertilizer (12-6-10-3) at two, five and nine months after planting; ii) FS-R- application of 150-150-120-45 kg/ha at planting plus 20 foliar applications of urea and potassium sulfate (50 kg/ha) every three weeks, rainfed; iii) FS-DI- application of 150-150-120-45 kg/ha at planting plus 20 foliar applications of urea and potassium sulfate (50 kg/ha), drip irrigation applied every three weeks; iv) FERT- application of 150-150-120-45 kg/ha at planting, but urea and potassium sulfate (50 kg/ha) were applied throughout fertigation; and v) CRF- same amount of nutrients as FS-R but N was applied as a controlled release fertilizer every six months. At Isabela, treatment FS-R produced the highest fruit weight (2.5 kg per fruit) and 1.5% of N in tissue, but did not differ significantly from FS-DI and CRF. Plants under CRF registered the highest Brix (15.8°). Although foliar fertilizer tended to produce higher yields, controlled release fertilizer is recommended because it eliminates the need for frequent foliar application without compromising yield.

The plant growth regulators, daminozide (2500 ppm), chlormequat chloride (1500 ppm), ethephon (500 ppm), mepiquat chloride (100 ppm), and paclobutrazol (1000 ppm), were foliar applied to sprouting-year and to first fruiting-year commercial lowbush blueberry (Vaccinium angustifolium Ait.). In sprouting-year blueberry, flower bud production was increased by paclobutrazol, resulting in significantly improved bloom and yield the following year. In fruiting-year blueberry, flower bud production was significantly increased by paclobutrazol in the year of application and resulted in improved bloom and yield in the following fruiting year. The effects of the other treatments on these parameters were in most cases not significant. Daminozide showed a significant bloom response with a sprouting-year application, but this did not translate into a yield response. Key words: Vaccinium angustifolium, plant growth regulators, paclobutrazol, flower bud production

Field experiments were conducted at Berrimah, Douglas Daly and Katherine in the Northern Territory (NT) during the 1987-88 and 1988-89 wet seasons to obtain yield data for kenaf (Hibiscus cannabinzis L. cv. Guatemala 4) grown under rainfed and irrigated conditions. Under rainfed conditions, maximum stem yield was obtained from sowings early in the wet season. Yield decreased with delay in sowing until the late-December-January period. The maximum rainfed stem yield at Katherine in an above-average rainfall season was 18 400 kg/ha. The maximum yield in a below average rainfall season was 11 700 kg/ha at Katherine, 9200 kg/ha at Douglas Daly and 9400 kg/ha at Berrimah. The applicability to the NT of growth and yield relationships established for irrigated kenaf in the Ord Irrigation Area (OIA) was assessed. The yield potential under irrigated conditions in the NT (21 600 kg/ha at 131 days after sowing) was higher than that reported elsewhere in Australia for the same growth period, but similar to that reported elsewhere for longer growth duration (180-300 days). In the NT, in contrast to the OIA, stem yield showed little or no response to N fertilisation. Stem yield was not related to N uptake, and at high levels of N application, there was marked N accumulation in the stem. Kenaf was able to accumulate up to 110 kg N/ha from the soil reserve where no N was applied. The yield response to plant density varied with the yield level and was similar to that in the OIA. Bark and core yield could be estimated directly from biomass, and indirectly from stem length and plant density, over a wide range of yield levels and cultural conditions. It was concluded that data relating to yield potential and response to N fertilisation cannot be transferred directly from the OIA to the NT.

Abstract The experiment was designed to study the effect of foliar fertilisation on the yield and some generative factors of maize in 2016. It was set on the territory of SZTE Tangazdaság Ltd in Hódmezővásárhely meadow chernozem soil. Three different foliar fertilizer products were applied in three replication randomised small plot experiment. The products were sprayed out individually and combined with each other as well, so there were six treatments and the control. In 2016 the amount of precipitation in the vegetation period of maize was higher than the average by 23.7 mm. Therefore this year was favourable for maize production. The data obtained during the experiment were processed by single factor variant analysis. Owing to the favourable dispersion of rainfall in the vegetative period of maize, the yields were relatively high. The average yield harvested from the control plots was 11.37 t/ha, and that of the treated parcels ranged from 11.61 and 12.86 t/ha. The foliar fertilizer products and their combinations increased the yield of maize, but this growing was not significant. By the using of foliar fertilization the generative factors of maize did not change significantly.
