The application of boron (200ppm) significantly (P < 0.05) increased the plant height and plant spread at 30, 60, and 90 DAT(cm), chlorophyll content (mg/g), fruit length (cm), fruit weight (g), fruit yield hectare-1(q), NP content in fruit (%), as compared to control and boron (100 ppm).

Effect of zinc and boron on the performance of rainy season local potato variety “Sete” (Solanum tuberosum L.) at Rukumkot, Rukum East, Nepal

A field experiment was carried out at Rukumkot, Rukum East, Nepal during the rainy season of 2021 to study the effect of boron and zinc on vegetative growth and yield parameters of the local “Sete” variety of potato. The experiment was laid out in a randomized complete block design (RCBD) with 4 replications, and 7 treatments i.e., control, boron @2kg/ha soil application, zinc @4.5kg/ha soil application, boron @2kg/ha + zinc @4.5kg/ha soil application, 0.1% boron spray, 0.1% zinc spray and 0.1% boron+ 0.1% zinc spray. The highest tuber yield per hill and productivity was reported in boron @2kg/ha + zinc @4.5kg/ha soil application i.e., 2888.52 grams and 27.51 ton/ha, respectively. A similar result was shown by zinc @4.5kg/ha soil application. Plant height (26.33cm, 46.57cm), number of branches (4.85, 12.02) and number of leaves per plant (30.05, 73.70) were significantly high in boron @2kg/ha + zinc @4.5kg/ha soil application at both 45 DAP (days after planting) and 60DAP. Soil application of only boron, only zinc and boron + zinc increased the total yield of tubers by 10.23%, 24.66% and 25.66%, respectively over the control. The foliar application of only boron, only zinc and boron + zinc increased the total yield of tubers by 4.22%, 2.07% and 12.37%, respectively over the control. Hence, research suggested combined soil application of zinc and boron at the rate of 4.5kg/ha and 2kg/ha, respectively over the foliar cum solitary application of micronutrients for increasing number of medium and large sized tubers and get an overall high yield of potato.

Impact of Foliar Boron Application on the Growth and Yield of Summer Tomato

Tomato (Solanum lycopersicum) is one of the most significant vegetable crops in the world, due to increasing demand. To promote the availability of boron to the plant throughout crucial growth phases, which eventually leads to increased plant growth and greater yields, foliar boron spray is intended to promote plant growth and yields in summer tomatoes. For tomato plants, boron is a key component, and deficits can cause stunted growth, substandard fruit development, and lower yields. By giving the plant an easily accessible supply of the nutrient, boron application on the leaves can assist in addressing boron shortages in the plant. BARI Tomato-4 in the Bangladeshi district of Noakhali, we used four treatments, B0 (control), B1 (H3BO3 125 ppm), B2 (H3BO3 150 ppm) and B3 (H3BO3 175 ppm) so as to find out what factors have a substantial impact on summer tomato growth and output. Following those treatments produced the highest plant height (153.66cm), number of branches per plant (10.66), no. of clusters per plant (7.66), no. of flowers per cluster (8.33), weight of each fruit (83.66 gm), number of fruits per plant (34.33), and yield (22.43 tone) (H3BO3 150ppm). Treatment T0 (control) produced the lowest plant height (143.33 cm), number of branches per plant (6.66), number of clusters per plant (6.66), number of flowers per cluster (6.67), weight of each fruit (79.33 g), number of fruits per plant (31) and yield (21.33 tons), followed by treatments B1 (H3BO3 125 ppm), B2 (H3BO3 150 ppm), and B3 (H3BO3 175 ppm). In our study showed that development and productivity of summer tomatoes, growers higher by the use of boron at 175 ppm.

Studying the impact of spur location and zinc and boron spraying on certain growth and flowering characteristics and yield of the Ibrahimi apple variety was conducted in one of the private orchards in a city in the Al-Saqlawiyah sub-district, Fallujah district, Anbar governorate, during the seasons 2021 and 2022. Fifty-four trees with rather consistent growth were chosen at the age of five years and planted on plots measuring 4 meters by 4 meters. The trees were sprayed with zinc (ZN0, ZN1) and boron (B0, B1, B2) twice yearly in a factorial experiment with a 3X3X2 RCBD randomized complete block design, where the first factor represents the selection of the spur site and its symbol (S1, S2, S3), the second factor is spraying, and the third factor is spraying. A considerable rise in the investigated characteristics was seen after spraying with the components under investigation (average fruit size, average fruit diameter, percentage of fallen fruits and percentage of remaining fruits).

Effect of Nano-Fertilizer and Boron on Vegetative Growth Characteristics of Two Hybrids of Cabbage Plant (Brassica oleracea var. Capitata L.)

Research into the impact of spraying balanced Nano-fertilizer and boron on the vegetative growth characteristics of two hybrids of the cabbage plant, Brassica oleracea var. capitata L., was conducted during the 2021/9/1 agricultural season at the Horticultural Research Station and Landscape - Agriculture College - Tikrit University. There were three variables in this study: the first was the concentration of the balanced Nano-fertilizer NPK (30, 20, 0 gL-1), the second was the concentration of the boron spray (5, 10, 20 mgL-1), and the third was the hybrids (Dlal, Globe Master). Duncan’s multiple range test was utilized for the statistical analysis, with a significance level of 5%. Duncan’s multiple range test with a 5% significance level was used to compare the outcomes. In summary, the study found that spraying the plant with a concentration of 30gL-1 of Nano-fertilizer significantly increased plant height, the number of outer and inner leaves of the head, and the length and width of the longest leaf, while spraying with a concentration of 20mg L-1 gave the highest value in the rate of dry material. Height, number of outer and inner leaves of the head, chlorophyll, and leaf area were all significantly boosted when the plant was sprayed with 5mg L-1 of boron. The hybrid Dlal outperformed the hybrid Globe Master in every growth-related quality tested, especially in terms of leaf characteristics.

Foliar Spray of Micronutrients Alleviates Heat and Moisture Stress in Lentil (Lens culinaris Medik) Grown Under Rainfed Field Conditions.

The simultaneous occurrence of high temperature and moisture stress during the reproductive stage of lentil (Lens culinaris Medik) constrains yield potential by disrupting the plant defense system. We studied the detrimental outcomes of heat and moisture stress on rainfed lentils under residual moisture in a field experiment conducted on clay loam soil (Aeric Haplaquept) in eastern India from 2018 to 2019 and from 2019 to 2020 in winter seasons. Lentil was sown on two dates (November and December) to expose the later sowing to higher temperatures and moisture stress. Foliar sprays of boron (0.2% B), zinc (0.5% Zn), and iron (0.5% Fe) were applied individually or in combination at the pre-flowering and pod development stages. High temperatures increased malondialdehyde (MDA) content due to membrane degradation and reduced leaf chlorophyll content, net photosynthetic rate, stomatal conductance, water potential, and yield (kg ha–1). The nutrient treatments affected the growth and physiology of stressed lentil plants. The B+Fe treatment outperformed the other nutrient treatments for both sowing dates, increasing peroxidase (POX) and ascorbate peroxidase (APX) activities, chlorophyll content, net photosynthetic rate, stomatal conductance, relative leaf water content (RLWC), seed filling duration, seed growth rate, and yield per hectare. The B+Fe treatment increased seed yield by 35–38% in late-sown lentils (December). In addition, the micronutrient treatments positively impacted physiological responses under heat and moisture stress with B+Fe and B+Fe+Zn alleviating heat and moisture stress-induced perturbations. Moreover, the exogenous nutrients helped in improving physiochemical attributes, such as chlorophyll content, net photosynthetic rate, stomatal conductance, water potential, seed filling duration, and seed growth rate.

Silicon foliar spraying in the reproductive stage of cotton plays an equivalent role to boron in increasing yield, and combined boron-silicon application, without polymerization, increases fiber quality

Foliar spraying of a boron (B) + silicon (Si) mixture (1.50 g L-1 of B + 1.15 g L-1 of Si) during the reproductive stage of cotton plants could benefit both crop yield and fiber quality; however, further research is needed to confirm this hypothesis. Two experiments were carried out under field conditions, using the FM 906 GLT cotton cultivar, with experiment I conducted in the 2018/2019 growing season and II in 2019/2020. A randomized block design was used for both experiments, consisting of four treatments: water; foliar boron; foliar silicon; and foliar boron + silicon and six replications. A preliminary laboratory test was performed to assess the turbidity of B and Si solutions and determine their compatibility in a mixture. Four foliar applications were performed, beginning in reproductive stage B1, at intervals of 7–11 days. Foliar spraying of B alone was efficient in increasing concentrations of the micronutrient in cotton leaves and fiber. Silicon foliar application was also efficient in raising concentrations in leaves and fiber. Silicon + boron proved to be efficient in supplying cotton plans with both the micronutrient and the element. The internal CO2 concentration and photosynthetic rate of plants treated with B, Si or B+Si were higher than those observed in controls, with no difference between these treatments. The addition of Si to the boron spray solution (B+Si) and Si application alone (Si) increased WUE, with no difference between these treatments, compared with B and controls. Boron, Si and B+Si increased cotton fiber yield, in relation to the control treatment. Individual and combined (B+Si) application of B and Si increased the micronaire values and cotton fiber length in both growing seasons studied. Applying only B or Si also improved the tensile strength of cotton fibers in relation to controls and the highest value for this variable in both experiments was obtained when plants were treated with the B+Si mixture. Foliar spraying of B reduced the short fiber content when compared to controls and applying Si alone or added to the boron solution produced the lowest result for this parameter. Our results demonstrate that foliar Si spraying has an equivalent effect to B on the yield and fiber quality of cotton, and that combining the two elements is particularly beneficial to cotton fiber, improving its tensile strength and reducing short fiber content.

Effect of foliar application of boron and molybdenum on yield and yield attributes of cauliflower in Kullu valley of Himachal Pradesh

A field experiment was carried out during kharif 2021 at experimental farm of CSK HPKV Hill Agriculture Research and Extension Centre, Bajaura, Kullu comprising of eleven treatments replicated thrice in randomized block design to evaluate the effect of foliar application of boron and molybdenum on productivity and quality of cauliflower. All these combinations received recommended dose of FYM @20 q ha-1 uniformly except the treatment NPK alone. Three foliar applications of boron at three concentrations (0.034%, 0.051% and 0.068%) and molybdenum (0.10%, 0.15% and 0.20%) were done at 30, 45 and 60 days after transplanting. The yield attributes and yield were significantly affected by the foliar spray of boron and molybdenum. Although the interaction between boron and molybdenum was found to be non-significant for yield and significant for yield attributes except curd diameter. Among three boron and molybdenum levels maximum marketable curd yield (257.5 q ha-1), (257.2 q ha-1) was obtained from the treatment where B @ 0.068% and Mo @ 0.20 % was applied respectively. But the interaction effect of boron and molybdenum on curd yield was found to be non-significant. To conclude, foliar application of B and Mo positively influenced the productivity and quality in Kullu valley of Himachal Pradesh.
