Lentil (Lens culinaris) is an important winter season annual legume crop known for its highly valued seed in human and animal nutrition owing to its high lysine and tryptophan content. Shortage of water during the crop growth period has become the major impediment for cultivation of pulses in rice fallow in particular. Under such conditions, the application of hydrogel can be a potential alternative to improve photosynthetic efficiency, assimilate partitioning, and increase growth and yield. A field experiment was conducted from November to February during 2015–16 to 2017–18 on clay loam soil that was medium in fertility and acidic in reaction (pH 5.4) at Central Agricultural University, Imphal, Manipur. The experiment was laid out in split plot design with three replications. There were three hydrogel levels in total in the main plot and foliar nutrition with five different nutrient sprays in sub-plots, together comprising 15 treatment combinations. The data pooled over three years, 2015–2018, revealed that application of hydrogel at 5 kg/ha before sowing recorded a significantly greater number of pods per plant (38.0) and seed yield (1032.1 kg/ha) over the control. Foliar application of nutrients over flower initiation and pod development had a positive effect on increasing the number of pods per plant eventually enhanced the seed yield of lentil. Foliar application of either 0.5% NPK or salicylic acid 75 ppm spray at flower initiation and pod development stages recorded significantly more pods per plant over other nutrient treatments. Further, the yield attributed improved because of elevated growth in plant. Significantly maximum seed yield (956 kg/ha) recorded in the NPK spray of 0.5% remained on par with salicylic acid 75 ppm (939 kg/ha) over the rest of the treatments.

Abstract Insect damage in canola adversely affects its productivity andquality and is considered one of the most important degrading factors in Egypt. The effect of foliar application of salicylic acid (SA) on aphid populations, growth and yield of canola (Brassica napus, L.) cv. serw 4 was the major goal of this study. Two experiments were conducted at the farm of Faculty of Agriculture, Suez Canal University, Ismailia, Egypt, during 2014 and 2015 seasons, to achieve this target. Each experiment included four levels of SA (0, 50, 100, 200 mg 1-1). The experimental results revealed that SA, at low concentration (50 mg 1-1), was an effective treatment for reduction the number of aphid populations and colony depth on the main inflorescence, contributed with reducing the thickness of secretory tissue of flower pedicel. The level of 50 mg 1-1 of SA-treated canola had the highest number of stomata cm-2, along with the lowest width of both stoma and its aperture. Thickness of xylem tissue and the number of xylem vessels bundle-1 in leaf midrib, reducing sugars and free amino acids was increased at 50 mg 1-1 SA, but free phenolics content did not affected significantly. Under controlled conditions, changes in temperature of infected leaves allowed the discrimination between healthy and infected areas in thermo-image, even before visible symptoms of aphid infestation appeared. The detection of modifications in plants or canopies, associated with low insect severity in the early stages of infestation, was crucial for the targeted, site-specific or on demand application of integrated aphid control. Canola, which was treated with 50 mg 1-1 of SA, gave 30.5 and 27.9 kg of oil ha-1 over the control. It was concluded that spraying of SA at 50 mg 1-1 was an effective elicitor to diminish the aphid numbers on canola inflorescence and improve its yield.

Loss of seed quality in soybean is a serious problem in tropical and subtropical region. Foliar application of salicylic acid (SA), GA3 and acetyl salicylic acid (50 ppm) at seedling and pod filling stage, K2HPO4 (2%), a-tocopherol (100 ppm) at flowering and pod filling stage was done on soybean varieties – NRC 7 and JS 335. Foliar application of SA showed positive effect on seed yield, seed health, germination and seed vigour during storage. Plant height was significantly improved by the GA3 spray in both the varieties. Significantly higher seed yield was obtained with foliar spray of a-tocopherol. Application of SA was found effective to protect plants from various diseases to get quality seed. a-Tocopherol and K2HPO4 treatment significantly reduced MDA production in seeds. a-Tocopherol application increased super oxide dismutase activity as a result the lipid peroxidation of seed during storage was significantly reduced. Application of a-tocopherol, K2HPO4 and salicylic acid improved the storage or keeping quality of soybean seed.

A field experiment was carried out at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, during rabi (winter) season of 2016-17 to evaluate the effects of fertilizer treatments on black cumin (BARI Kalozira-1). The field belongs to Shallow red-brown terrace soil of Salna series under AEZ-28 (Madhupur Tract). The experiment was laid out in randomized complete block design (RCBD) with three replications. Results showed that the application of nutrient elements had positive effect on plant height, branches per plant, capsule setting, umbels per plant, capsules per plant, capsule size, seeds per capsule, 1000-seed weight and seed yield of black cumin. The highest seed yield (1277 kg ha-1) was obtained from 75% RDCF + 25% cowdung-N treatment followed by 100% RDCF (N80P45K50S20Zn5B2 kg ha-1) and the lowest seed yield (420 kg ha-1) was recorded with 50% RDCF. Thus, the IPNS treatment 75% RDCF + 25% cowdung-N appeared to be the best suitable package for black cumin cultivation in this location.Bangladesh J. Agril. Res. 43(2): 205-210, June 2018

Plant Responses

Aspirin (Acetylsalicylic acid) is an important signal molecule modulating plant responses to stress. Drought significantly decreased the growth rate and impaired the yield of wheat. Acetylsalicylic acid can improve the performance of wheat under both well-watered and drought conditions. Applying salicylic acid at a relatively low concentration positively impacted the physiological, yield, and growth parameters. In order to determine the effect of foliar application of Aspirin levels on growth, yield, and its components of wheat, two experiments, i.e., control and rainfed, were conducted to evaluate the effect of salicylic acid were carried out at glasshouse of Research Area, Department of Agronomy and university research farm Koont of PMAS-Arid Agriculture University Rawalpindi during cropping season 2019-20. Four treatments of Aspirin (Control, 120 mg/L, 180 mg/L, and 240 mg/L) for glasshouse (Control, 20 g/L, 30 g/L, 40 g/L) for rainfed were applied, which are to be known as As0, As1, As2, and As3 for both experiments. Foliar application of Aspirin solution sprayed at growth stage 37 on the Zadoks scale. Results of experiments revealed that for the 180mg/L of Aspirin (As2), improved growth parameters such as plant height, spike length, number of spikelets, and increased the wheat crop yield. In contrast, for the rainfed experiment, the plant height, spike length, number of spikelets, and increased yield were observed by applying 30 g/L (As2) of Aspirin, and the lowest results of these parameters were recorded in control treatment for both control and rainfed experiments. The overall results of this study showed that among the levels of Aspirin, the application of treatment As2 both for control and rainfed experiment, i.e., 180 mg/L for control and 30 g/L for rainfed Aspirin, have positively impacted the growth and yield parameters of wheat and bought improvement in wheat production under plant stress environment.

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.
