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.

AbstractInterest in growing lentil (Lens culinaris Medik.) is increasing due to its potential returns relative to other legume crops in semi-arid areas. An experiment was conducted to examine the important traits on lentil under application of nano-fertilizer by using eight genotypes with application of the biplot technique in visualizing research data. Nano-iron oxide (2 g L-1) was utilized as foliar spray during vegetative and reproductive stages. The study revealed that genotype by trait (GT) biplot can graphically display the interrelationships among traits and facilitate visual comparison of genotypes. The first two principal components (PC1 and PC2) accounted for 76% of the total variation. The polygon view of GT biplot suggested four sections for the lentil genotypes as well as traits. The vertex genotypes G1 had plant height, number of branches per plant, number of pods per plant, 100-grains weight and grain yield traits. The most prominent relation were: a strong positive association among biological yield, number of branches per plant, number of pods per plant, grains yield and plant height as indicated by the small obtuse angles between their vectors. The traits’ relationship in the semi-arid was highly variable, and grain yield improvement can be achieved by selecting for number of pods per plant, 100-grains weight. We suggest that the GT biplot be used jointly to better understand and more fully explore interaction pattern data.

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.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to explore the growth and yield performance of boro rice cv. BRRI dhan28 is influenced by foliar spray of potassium nitrate (KNO3) at four rice growth stages. The experiment consisted of four doses of KNO3 viz. 0 (Control), 0.25, 0.50 and 1.00 kg ha−1 and applied at four growth stages of rice development viz. at panicle initiation, at ear emergence, at anthesis period and at dough stage. This experiment was carried out in Randomized Complete Block Design (RCBD) with three replications with 10 m2 (4.0 m × 2.5 m) unit plot size and spacing between blocks and unit plots was 1 m and 0.5 m, respectively. Results revealed that foliar application of potassium nitrate at four growth stages significantly affected yield and yield contributing characters of BRRI dhan28. But most of the yield contributing characters did not differ significantly due to the interaction between potassium nitrate and stage of foliar spray. However, the foliar application of KNO3 @ 0.25 kg ha−1 showed the highest yield production (5.86 kg ha−1) while the lowest yield (4.85 kg ha−1) was found in control. Furthermore, better yield performances were recorded when the KNO3 was applied at panicle initiation stage rather than the other four growth stages. The total number of tillers, 1000–grain weight and grain yield, was higher with foliar spraying of a 0.25 kg ha−1 KNO3 at panicle initiation stage. From this experiment, it may be concluded that foliar application of KNO3 affected the yield performances of BRRI dhan28 and 0.25 kg ha−1 KNO3 produced the highest grain yield when applied at panicle initiation stage of boro rice.

Potassium (K) is one of the limiting factors that negatively influenced rice growth and yield in submergence-prone soils. We conducted an experiment during the wet season of 2014–15 to achieve optimal doses of K and understand the effect of K application on submerged rice in terms of survival, chlorophyll content, non-structural carbohydrates (NSC), anti-oxidant activities and yield. Results revealed that chlorophyll and NSC content were significantly (P ≤ 0.05) lower whereas the activity of anti-oxidants (catalase, superoxide dismutase and total peroxidase) were significantly (P ≤ 0.05) higher after submergence compared with pre-submergence. Further, application of K at a higher basal dose (40 kg ha–1) was more beneficial to improve survival after de-submergence by maintaining NSC, chlorophyll content and higher activity of anti-oxidants with lower level of lipid peroxidation. Furthermore, results showed superiority of the treatments having application of higher doses with one foliar spray (T9–40 kg K2O ha–1 (basal) + one foliar spray at 0.5% K at panicle initiation (PI) stage) for grain yield. We conclude that application of a higher dose of K with one foliar application at PI stage is more beneficial to enhance plant survival, better recovery and yield gain of rice during complete submergence.

The Impact

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe and their proper management plays a vital role in optimizing crop yield. This field experiment was conducted to assess the impact of soil and plant nitrogen N and P ratio on the growth and yield of wheat (Triticum aestivum L.) in alkaline calcareous soil. The study consisted of various levels of nitrogen (0, 40, 80, and 160 kg ha−1 as urea) and phosphorus (0, 30, 60, and 90 kg P2O5 ha−1 as diammonium phosphate), and was carried out in randomized complete block design (RCBD) with factorial arrangement having three replications. The result showed that the addition of 160 kg N ha−1 significantly improved biological yield (10,052 kg ha−1), grain weight (3120 kg ha−1), chlorophyll content at tillering stage soil plant analysis development (SPAD) value (35.38), N uptake in straw (33.42 kg ha−1), and K uptake in straw (192 kg ha−1) compared to other N levels. In case of P, 90 kg P2O5 ha−1 had resulted maximum biological yield (9852 kg ha−1), grain yield (3663 kg ha−1), chlorophyll content at tillering stage (SPAD value 34.36), P (6.68 mg kg−1) and K (171 kg ha−1) uptake in straw. The sole use of N and P have positively influenced the biological and grain yield but their interaction didn’t response to biological yield. The present study reveals that SPAD value (chlorophyll meter) is the better choice for determining plant N and P concentrations to estimate the yield potential.

SUMMARYField experiments were carried out at Ludhiana in Punjab during 1982 and 1983 on the effect of foliar application of water spray or naphthalene acetic acid (NAA) at 100 and 200 mg/1 of water on the growth and yield of rice when applied at tillering and before panicle emergence stages of late-transplanted paddy grown under four levels of nitrogen (0, 60, 90 and 120 kg/ha). Foliar spray of NAA significantly increased the grain yield of paddy as compared with water spray under low levels of nitrogen (0 and 60 kg/ha) owing to increases in the number of ear-bearing shoots per plant, number of filled grains per panicle and grain weight. Chlorophyll content of leaves, leaf area index and interception of photosynthetically active radiation by the crop canopy also increased with foliar spray of NAA and application of nitrogen. Paddy responded significantly up to 90 kg N/ha in terms of grain yield whereas straw yield increased significantly up to 120 kg N/ha. However, grain mass declined significantly with increase in nitrogen from 90 to 120 kg/ha.

Abstract Semi-arid environments are characterized by low soil organic matter, lack of sufficient precipitation and occurrence of high temperatures at the terminal of growing season. Effects of foliar application of salicylic acid (SA) and ascorbic acid (AS) during vegetative and reproductive stages at three farmyard manure (FYM) rates (zero (FYM1), 15 (FYM2), 30 (FYM3)t·ha-1) were studied on the growth and yield components of lentil (Lens culinaris Medik.) under supplemental irrigation of semi-arid highland in the north-west of Iran. The results revealed that application of farmyard manure especially at high level could significantly increase the morp-ho-physiological traits such as plant height, first pod height, plant canopy spread, rooting depth, the number of root nodules, ground cover, chlorophyll content and relative water content. Although improving effects of SA and AS on growth parameter were less than FYM, plants treated with SA showed better performance than plants treated with AS. A similar status was observed for grain yield and yield component. So the highest grain yield was recorded at FYM by foliar application of SA. It can be concluded that FYM3 as the most promising manure application rate was adopted to improve both root and total above-ground plant growth. Also this work highlights the importance of exogenous application of growth regulators in lentil cropping systems in semi-arid region with the Mediterranean climate.

The study investigated the effect of foliar application of gibberellic acid (GA3) and cytokinin on antioxidative enzymes, chlorophyll content and grain yield of maize. Three factor randomized block design (RBD) was used to carry out the investigation in experimental farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar during 2012-13. The field experiment was laid out in Fe-deficient soil (Fe < 0.5 ppm) with contrasting cultivars of maize. The factors were: i) Fe-efficient (Suwan) vs. inefficient cultivar (Shaktiman-3); ii) ‘control’ (no Fe-spray) vs. one soil application of Fe (20 kg ha-1) + two foliar spray of Fe as 0.5% ferrous sulphate at pre-flowering and 7-days after flowering; and iii) foliar application of phytohormones viz., GA3 at10 and 20 ppm; cytokinin at10 and 20 ppm and their combinations. Application of Fe and phytohormones significantly increased enzymes activity like catalase, peroxidise and superoxide dismutase. The highest activity was observed with combined application of cytokinin + GA3 at10 ppm. For example, the value of catalase increased from 196.0 to 217.0 µmol/min/g fresh protein, and peroxidase from 90.0 to 103.0 Units mg-1 fresh protein. There were significant increases in chlorophyll content of leaves, and grain yield with combined application of cytokinin + GA3 at 10 ppm. The maximum chlorophyll content was recorded in ‘Suwan’ (32.7 SPAD value) having treatment Fe application plus GA3 + cytokinin at10 ppm each. Grain yield increased significantly from 58.6 to 64.6 q ha-1 in ‘Suwan’ provided with Fe application and GA3+ cytokinin at10 ppm each compared to control (50.3 q ha-1). Results indicated that phytohormones were involved in regulation of nutrient availability and conversely mineral nutrients influenced hormone biosynthesis suggesting a relationship between hormones and nutritional homeostasis. Conclusion: Exogenous application of phytohormones could alleviate Fe deficiency stresses in maize and application of Fe and phytohormones acted synergistically. Hence, application of GA3 + cytokinin at 10 ppm may be done to alleviate Fe stress and to improve grain yield of maize.

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.

This study was carried out with a view to evaluating the effect of foliar application of urea on BRRI dhan29. The experiment was laid out in a RCBD design with seven treatments (T1 : Full dose of prilled urea @ 140 Kg N ha-1) (control), T2 (50% prilled urea + 5 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1),T3 (70% prilled urea + 3 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1), T4 (50% prilled urea + 3 foliar spray @ 1.0% N solution @ 11 kg N spray-1), T5 (50% prilled urea + 5 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1 + 5 t ha-1 cow dung), T6 (70% prilled urea + 3 foliar spray @ 0.5% N solution @ 5.5 kg N spray-1 + 5 t ha-1 cow dung) and T7 (50% prilled urea + 3 foliar spray @ 1.0% N solution @ 11 kg N spray-1 + 5 t ha-1 cow dung) and three replications. Soil and foliar application of nitrogen significantly influenced the growth and yield contributing characters like plant height, panicle length, and effective tillers hill-1 as well as the grain and straw yields of the crop. The treatment T5 produced the highest grain yield (6.68 t ha-1) which was statistically similar to yield from T7, T6. Treatment T2,T3 and T4 gave similar yield. The grain yields of these treatments were higher than those of T1 treatment (soil application of urea only). The T5 also produced the highest straw yield of the crop. The lowest grain yield of 4.72 t ha-1 and the lowest straw yield of 5.17 t ha-1 were recorded with T1 (control).Res. Agric., Livest. Fish.3(1): 79-85, April 2016
