Vasicine is a quinazoline alkaloid present in Adulsa. An experiment was conducted to assess the impact of vasicine on growth, photosynthesis and yield of tomato under pot culture. Vasicine was applied as soil application in the form of vigo @ 4 kg acre-1 (50% as basal and 50% at 15 days after transplanting), and as foliar application in the form vigo @ 2 mL L-1 at 15 and 30 DAT and both combined soil and foliar application. Combined application of vasicine in the form of vigo through soil and foliar spray increased leaf area by 16.9% and soluble protein by 24.02% over control. This is on par with foliar application of vigo @ 2 mL L-1 twice at 15 and 30 days after transplanting. Tallest plant (116.56 cm) and longest root length (73.25 cm) were observed in combined soil and foliar application of vasicine. Combined application recorded higher total chlorophyll content (1.34 mg g-1) followed by foliar application (1.18 mg g-1) compared to control (1.09 mg g-1). Combined application of vasicine through soil and foliar recorded the highest fruit yield of 26.23 t ha-1 which is on par with foliar spray of vigo @ 2 mL L-1 (25.68 t ha-1) and least recorded in control (21.52 t ha-1). Vasicine might compose of growth hormones like auxin, gibberellins and cytokinin, which are playing a major role in plant growth and metabolism. Hence, the new biostimulant vasicine showed its positive impact on growth and yield in tomato.

Abstract The effort to achieve higher yields at the required qualitative level has led to the intensive studying the problems of the rational usage of the titanium containing fertilisers by the agricultural research in the course the previous thirty years. Therefore, the objective of the experiment was to evaluate the impact of two doses of Mg-Titanit (0.2 l/ha and 0.4 l/ha) on the formation of the aboveground and underground phytomass, also on the total chlorophyll in leaves, on the titanium and nitrogen content in the seeds and straw, on the quantity and quality of winter rape yield. The doses were applied two or three times on the leaves of winter rape (BBCH 50-52, BBCH 59, BBCH 66-67). The experiment was realized on the Haplic Chernozem (48°42´ N, 17°70´ E - Western Slovakia) during two farming years (2009/2010 and 2010/2011). The results showed that all three applications of Mg-Titanit in both doses stimulated the formation of aboveground and underground phytomass of winter rape. The highest growth of phytomass was detected after the second application. The application of Mg-Titanit in the growth phases BBCH 50-52 and BBCH 59 increased the contents of both chlorophylls (a and b), where the growth of chlorophyll b content was more considerable than the growth of chlorophyll a content. The third spraying by Mg-Titanit decreased the content of the total chlorophyll. The application of Mg-Titanit had the positive impact on the yield of seeds, straw and fat content in the winter oilseed rape seeds.

Nano-fertilizers are new generation of the synthetic<em> </em>fertilizers which contain readily available nutrients in nano scale range. Nano fertilizers are preferred largely due to their efficiency and environment friendly nature compared to conventional<em> </em>chemical<em> </em>fertilizers. To evaluate the effects of foliar spray<em> </em>of micronutrient nano-fertilizer (iron and zinc) and nano-titanium dioxide (nTiO<sub>2</sub>) solution on grain yield and its components in barley under supplemental<em> </em>irrigation conditions, a field experiment was carried out in the semi-arid highland region of Maragheh, Iran. Barley plants were separately treated with of chelated nano-scale zinc oxide (ZnO) and ferric oxide (Fe<sub>2</sub>O<sub>3</sub>) suspensions during tillering stage, booting and milky stages. Results revealed that days to<em> </em>anthesis and maturity significantly increased after application of both nano-fertilizers. Furthermore<em>,</em> a considerable improvement was observed in grain mass, spike length, number of the grains per spike, chlorophyll content, grain yield and harvest index by application of nano-fertilizer. However the impact of nano zinc fertilizer was more prominent than iron. Foliar application of nTiO<sub>2</sub> positively affected some morphophysiological characteristics like as days to<em> </em>anthesis, chlorophyll content and straw yield. The results suggest that the delivery of Zn into barley seedling through spray of nano-fertilizer can be an efficient nutrient management strategy in semi-arid regions. Overall, our result indicated that the integration of nanotechnology in fertilizer products can improve fertilizer use efficiency and significantly increase of barley yield. However, plant response to nanoparticles significantly depend on concentration and time of application as well as size, shape, and surface functionalization of the particles.

Waterlogging Treatment

The effectiveness of exogenous application of K in ameliorating the adverse effects of waterlogging on cotton plants was assessed under greenhouse conditions. Forty-day-old plants were subjected to continuous flooding for 1 week and then K (60 kg ha–1) was applied either as soil application, foliar spray, or in combination. The waterlogging treatment significantly reduced plant height and fresh and dry biomass, photosynthetic pigments, gas exchange parameters and nutrient accumulation (N, K+, Ca2+) in stem, root and leaves of cotton plants, Although Mg2+ content in roots increased significantly due to waterlogging, it was not affected in stem or leaves. In contrast, Mn2+ and Fe2+ contents generally increased under waterlogged conditions. All water relation parameters were also significantly influenced by waterlogging stress. Waterlogged plants supplemented with K showed a significant improvement in growth, photosynthetic pigments and photosynthetic capacity. Potassium supplementation also improved nutrient uptake of waterlogged plants and resulted in significantly higher accumulation of K+, Ca2+, N, Mn2+ and Fe2+ than those plants not supplied with K. Although all modes of K application were effective in mitigating the inhibitory effects of waterlogging, the combined application through soil + foliar spray yielded the best results and the foliar application (alone) being the least effective.

Aim: To determine the impact of soil and foliar application of ZnSO4.7H2O at late stages of wheat as heading initiation (5% ear formation), 100% heading (complete ear formation) and heading initiation and 100% heading along with recommended dose of fertilizer on growth, yield and quality of zero till wheat. Methodology: The field experiment was conducted on zero till wheat. The treatments consisted of control (no Zn), soil application of 12.5, 25, 37.5, 50 kg ha-1 ZnSO4.7H2O and foliar application of 0.5% Zn as one spray at heading initiation (5% ear formation), one spray at 100% heading (complete ear formation) and two sprays at heading initiation and 100% heading with recommended dose of fertilizer. These treatments were evaluated in RBD with three replications. Results: Soil application of 50, 37.5 and 25 kg Zn ha-1 with two foliar sprays of 0.5% at heading initiation (5% ear formation) and 100% heading (complete ear formation) stages gave significantly higher average grain and straw yield and Zn concentration in grain than other treatments, including control. Interpretation: Enhanced application of Zn as soil and foliar application ameliorates soil Zn deficiency and increases protein content in grains, which might influence the quality and yield of zero tilled wheat.

Water spinach (Ipomoea reptans Poir) had been identified as a nutritious vegetable with high demand in Indonesia. Besides, this plant also has been evidenced to play an important role in environmental cleaning as phytoremediator. The study about the effect of organic fertilizers on the growth and yield of water spinach (Ipomoea reptans Poir) has been conducted in the Green House of Biology Department, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan. The study aims to investigate the most effective type of fertilizers and the dose for water spinach’s (Ipomoea reptans Poir) growth and yield. A Completely Randomized Factorial Design was designed for the experiment with two factors and three repetitions. The first factor is the type of fertilizer (chicken manure, cow manure, and compost), and the second factor is the dose of the fertilizer (1:1, 2:1, and 3:1). The parameters such as plant height, number of shoots, number of leaves, fresh weight, dry weight, leaf’s total chlorophyll content, and water content were measured to evaluate plant growth and yield. The General Linear Model used SPSS 21 programs was applied to analyze the collected data. Study results revealed that cow manure increased plant growth and yield significantly with dose 2:1 as the finest treatment, followed by dose 3:1. Cow manure also increased total chlorophyll content (8.0574c mg. L-1), with the most suitable dose was 2:1 (8.2807 mg. L-1). The plant’s water content tended to be high in chicken manure (93%), and the lower water content was in cow manure with dose 3:1 (87.5%).

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.

The Impact

Incessant application of chemical fertilizers to the agricultural fields may alter the composition and activities of soil microbiota. Thus, the shift of cultivation practices from chemical to organic is considered to be the need of the hour in order to maintain soil health. A study was conducted in the agricultural fields of the University of Burdwan, India to observe the impact of organic manure on rhizosphere bacterial community. The experiments were conducted on maize plants, supplemented with the recommended dose of chemical fertilizer and organic manure (vermicompost and cow dung mixture). Corresponding changes in the plant phenological events and soil health in terms of soil physico-chemical factors and rhizosphere bacterial groups up to the level of CFU g-1× 105 dry soil were noted.The results showed a significant increase in population of nitrifying bacteria, asymbiotic nitrogen-fixing bacteria and protein hydrolysing bacteria in the organically treated plots. Moreover, the organic manure increases the bacterial population of rhizosphere, which in turn has a positive impact on maize growth and yield. The growth of the three groups of bacteria was attributed to the type of organic manure supplied to the agricultural fields.In addition, strong correlation was observed between Zn and protein hydrolysing bacteria. The soil organic carbon and available nitrogen were strongly correlated with nitrifying, fat solubilizing and phosphate solubilizing groups of bacteria.

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.
