Abstract Foliar nitrogen (N) application is considered an important factor affecting phenology, growth, yield, and yield components of dryland wheat (Triticum aestivum L.). A field experiment was conducted to study effects of foliar N on dryland wheat (cv. Prisabk-2004) at the Agronomy Research Farm, The University of Agriculture Peshawar, Pakistan, during winter 2010-2011. The experiment was laid out in randomized complete block design using four replications. A plot size of 3 m by 4 m, having 8 rows, 4 m long and 30 cm apart was used. A total of 80 kg N ha−1 in the form of urea was applied. Out of 80 kg N ha−1, 70 kg N ha−1 was applied to the soil at sowing time, and the remaining 10 kg N ha−1 was applied in the form of foliar spray (2% N). The required foliar N was applied in various combinations (splits) at different growth stages viz. 30, 60, 90 and 120 days after emergence (DAE). Phenological development (days to anthesis and physiological maturity) was delayed, yield components and yield increased significantly (p ≤ 0.05) with foliar N over control (water spray without N). Wheat grain yield increased to the highest level (4427 kg ha−1) when 100 % foliar N was applied (no split) at 90 DAE, followed by 4050 kg ha−1 at 120 DAE, while the control (no foliar N) resulted in the lowest grain yield (2573 kg ha−1). We concluded from this study that 2 % foliar N application in a single split either at 90 or 120 DAE could improve wheat productivity under dryland condition.

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.

 The objective of this study was to investigate the effect of some amino acids on tillering and grain yield of bread wheat cultivars. A field experiment was carried out at the agricultural experiment station, College of Agriculture Engineering Sciences, University of Baghdad during the two winter seasons, 2016-2017 and 2017-2018. Randomized Complete Block Design within split plots arrangement was used in three replicates. The experiment included two factors, the first (main plots) was the wheat cultivars (IPA 99, Buhooth 22, and Abu-Graib3) and the second (sub-plots) was foliar application three amino acids (L-Tryptophan, L-Glycine, and L-Lysine) with concentrations 50 and 100 mg L-1 and the amino acid L-Cystine at 100 and 150 mg L-1 and control treatment. The treatments of foliar application were applied during two growth stages, the first was when the main stem had three leaves (ZGS: 13) and the second was when the plant entered the flowering stage (ZGS: 60). Results showed the significant superiority of Buhooth 22 in most growth traits, which produced the highest number of tillers.m-2 (556.30 and 568.15 tillers m-2), number of spikes (476.74 and 494.19 spikes m-2), weight of 1000 grains (31.09 and 32.43 g), and grain yield (5.39 and 5.15 Mg ha-1) for the two seasons respectively. The treatment of foliar application L-Tryptophan at 50 mg L-1 was significantly superior in most traits of yield components which produced the highest values of the number of tillers (616.89 and 627.78 tillers m-2), number of spikes (477.00 and 944.67 spikes m-2), weight of 1000 grains (32.01 and 33.55g), and grain yield (5.77 and 5.33Mg ha-1) in the two seasons, respectively. The response of wheat cultivar growth and yield to amino acids differed significantly.

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.

A field experiment was conducted during Kharif 2018 at College Farm, College of Agriculture, PJTSAU to evaluate the effect of various sources of zinc and iron on grain yield, nutrient uptake and grain quality parameters of finger millet. The experiment was laid out in a randomized block design with 14 treatments and replicated thrice.The results revealed that application of different Zinc and iron sources at different rates significantly influenced the grain yield, nutrient (N, P and K) uptake and grain quality parameters (protein and calcium content) of finger millet. Highest grain yield (3653 kg ha-1), protein (11.25%) and calcium content (2.33%) in grain were obtained in the treatment receiving RDF + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF + foliar application of Fe-humate twice at 30 and 60 DAS (3612 kg ha-1, 10.90% and 2.0%) and the lowest grain yield (1995 kg ha-1), (6.25%) and calcium content (1.10%) were recorded with application of RDF alone. The nutrient uptake (N, P, K and Fe) at all the crop growth stages was significantly higher with the treatment receiving RDF (60:40:30 kg N,P2O5 and K2O kg ha-1) + foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with treatment receiving RDF+ foliar application of Fe-humate twice at 30 and 60 DAS. Highest iron uptake was recorded in treatment receiving RDF+foliar application of FeSO4 @ 0.5% twice at 30 and 60 DAS which was on par with T8, T14 treatments.The highest nutrient uptake of Zinc was obtained in treatment receiving RDF + Zn Humate foliar spray @ 0.25% twice at 30 and 60 days after sowing which was on par with treatment receiving RDF + Zn Humate soil  application. Contrary to the grain yield, nutrient uptake, protein and calcium content there were no significant differences between treatments with respect to Zn, Fe and carbohydrate content in grain.

O girassol é uma planta que se adapta em diversas condições edafoclimáticas, porém, as necessidades hídricas, assim como os coeficientes de cultura nos diferentes estádios fenológicos, ainda não estão perfeitamente definidas. Na região do Arenito Caiuá, Noroeste do Estado do Paraná, por possuir solo extremamente arenoso, portanto com baixa capacidade de retenção hídrica, torna-se imprescindível o cultivo de culturas anuais sob a técnica de semeadura direta. Com objetivo de estabelecer um manejo adequado de irrigação suplementar para a cultura do girassol nesta condição, valores de coeficiente de cultura foram propostos em cinco fases fenológicas. Utilizou-se um delineamento experimental de blocos casualizados com três repetições e cinco tratamentos, sendo um sem irrigação e quatro com lâminas de irrigação embasadas na adoção de diferentes coeficientes de cultura.  Ao final de cada fase foram medidas as seguintes componentes de produção: massa seca, diâmetro de capítulo, diâmetro de caule e altura de planta. A maioria das componentes respondeu de maneira linear, independente da fase analisada. Não houve baixa produtividade da cultura do girassol com ausência de irrigação, igual a 2271 kg ha-1, no entanto a maior produtividade, 3063 kg ha-1, foi alcançada por meio da irrigação que utilizou coeficientes de cultura iguais 0,4, 0,8, 1,2, 0,8 e 0,4, nas fases 1,2,3,4 e 5, respectivamente.   Palavras Chave: coeficiente de cultura, componentes de produção, irrigação suplementar, solo arenoso, Helianthus annuus L.     SUNFLOWER GROWTH AND YIELD UNDER IRRIGAGATION LEVELS IN NO-TILLAGE SYSTEM IN ARENITO CAIUÁ REGION - PARANÁ STATE.     2 ABSTRACT   The sunflower crop adapts various soil and climate conditions, however, the water requirements and the crop coefficients in different growth stages are not yet well defined.In Arenito Caiuá, Northwest of Parana State, because the soil is extremely sandy with low water retention capacity, there is a need for annual crops cultivation under no-tillage technique. In order to establish a proper supplemental irrigation management for sunflower cultivation in this condition, crop coefficient values were proposed in five phases of development. A randomized block design was used with three replications and five treatments, one without  and four irrigation depths based in the adoption of different crop coefficients. At the end of each phasethe following yield components were measured: dry matter, capitulum and stem diameter, and plant height. Most components responded in a linearly, independent of the phase analyzed. There wasn’t sunflower low yield without irrigation equal to 2271 kg ha-1, however the highest yield 3063 kg ha-1 was obtained by irrigation which used crop coefficients equal to 0.4, 0.8, 1.2, 0.8 and 0.4 in phases 1,2,3,4 and 5, respectively.   Key-words: crop coefficients, yield components, irrigation, soil, Helianthus annuus L.

Moringa Leaf Extract

Moringa oleifera leaf extract has a potential effect as a growth enhancer of many crops. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the effect of foliar application of moringa leaf extract on growth and yield of late sown wheat (BARI Gom-26). The experiment was laid out in a randomized complete block design with six treatments and three replications. The treatments were T1 (Control), T2 [moringa leaf extract (MLE) sprayed only at tillering stage], T3 (MLE sprayed at tillering and jointing stages), T4 (MLE sprayed at tillering, jointing and booting stages), T5 (MLE sprayed at tillering, jointing, booting and heading stages), and T6 (MLE sprayed only at heading stage). Application of moringa leaf extract significantly increased the growth and yield attributes as well as grain and straw yield of wheat. Among various treatments with moringa leaf extract the performance of T4 (MLE sprayed at tillering, jointing and booting stages) was the best as it produced the tallest plant (87.87 cm), the highest fresh and dry weight of root (16.51 g and 11.37 g respectively), the highest number of spikelets spike-1 (19.70) and filled grains spike-1 (45.53), as well as the highest grain and straw yield (3.62 t ha-1 and 5.43 t ha-1 respectively) of wheat. Therefore, moringa leaf extract as a foliar spray can be applied at critical growth stages to increase the growth and yield potentiality of late sown wheat.Asian J. Med. Biol. Res.

Nitrogen (N) is a key growth and yield-limiting factor in cultivated rice areas. This study has been conducted to evaluate the effects of different conditions of N application on rice yield and yield components (Shiroudi cultivar) in Babol (Mazandaran, Iran) during the 2015- 2016 season. A factorial experiment executed of a Randomized Complete Block Design (RCBD) used in three iterations. In the first factor, treatments were four N amounts (including 50, 90, 130, and 170 kg N ha-1), while in the second factor, the treatments consisted of four different fertilizer splitting methods, including T1:70 % at the basal stage + 30 % at the maximum tillering stage, T2:1/3 at the basal stage + 1/3 at the maximum tillering stage + 1/3 at the panicle initiation, T3: 25 % at the basal stage + 50 % at the maximum tillering stage + 25 % at the panicle initiation, and T4: 25 % at the basal stage + 25 % at the maximum tillering stage + 50 % at the panicle initiation. The results illustrate only the number of panicles (m2) which was significantly impacted by the year (at the CI of 0.99). Different levels of N had effects on the panicle length, the percentage of filled grain (PFG), whole grain in a plant, and yield (at the CI of 0.95). The panicle length, the PFG, and yield were also significantly affected by different methods of N splitting (at the P-v of 0.01). The interaction of N amount × N splitting had a significant effect on the panicle length, the PFG, and yield (at the CI of 0.95).  In general, the most significant impact on the panicle length, the number of panicles (m2), the whole plant's grain, and yield observed after using 130 kg N ha-1.  Besides, T3 showed the most notable effect on all the studied indices except for the panicle length.

Plant growth regulators like naphthalene acetic acid (NAA) positively affect the growth and yield of crop plants. An experiment was conducted to check the foliar application of NAA on growth and yield components of cotton variety Bt.121 under field condition at research area of agriculture farm near Cholistan Institute of Desert Studies (CIDS), The Islamia University of Bahawalpur, Pakistan. The experiment was comprised of foliar application of NAA (1%) viz. T0 (control), T1 (One spray of NAA), T2 (Two sprays of NAA), T3 (Three sprays of NAA), T4 (Four sprays of NAA). The first foliar spray was applied at 45 days after sowing (DAS) and later on it was continued with 15 days interval with skilled labour by hand pump sprayer. The experiment was laid out in randomized complete block design and each treatment was replicated three times. Data recorded on growth, chlorophyll contents, yield and yield components showed a significant increase with the application of NAA. Furthermore, earliness index, mean maturity date and production rate index were also influenced with foliar application of NAA. On the basis of growth and yield parameters it can be concluded that four spray of NAA (1%) can be applied commercially under field conditions.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.
