Ameliorative Effect

In present study, different foliar treatments were applied on peanut to check their ameliorative effect on Fe deficiency. In hydroponics experiments, foliar applications of FeSO4, Fe-EDTA, sequestrene and ferric chloride were applied to check their effect on Fe deficiency chlorosis in two varieties of peanut already screened as BARI-2000 (Fe deficiency tolerant) and BARD-699 (Fe deficiency sensitive). Sequestrene proved to be more effective in increasing the growth of plant. Photosynthetic rate increased up to 58 and 70% in BARI-2000 and BARD-699 respectively as compared to control with foliar application of sequestrene. Similarly higher active Fe concentration was recorded in both genotypes. Up to 14 and 41% increase in active Fe concentration was observed. Various morpho physiological parameters including root length, shoot length, root fresh weight, root dry weight, shoot fresh and shoot dry weights, SPAD values, photosynthetic and transpiration rates showed that BARD-699 was more responsive to foliar applications, while foliar application of sequestrene can be used in correcting Fe deficiency in both genotypes. Active Fe was significantly correlated with different morphological parameters in both genotypes. The results of presense experiment suggested that foliar applications were helpful in correction Fe deficiency in peanut and growth can be enhanced.

Iron Sulphate

A severe iron deficiency in peas grown on grey to black clay loam soil overlying limestone (rendzina) was successfully ameliorated by foliar application of ferrous sulphate. Two applications, three weeks apart, increased the fresh weight of peas harvested by more than 100 per cent (P < 0.001). The two sprays also increased the numbers of pods, dry weight of the pods, fresh weight per pea and maturity of the peas (all P < 0.001), and herbage yield (P < 0.01). One application of iron sulphate was insufficient to arrest completely the symptoms of iron deficiency. The peas did not show vegetative or marsh spot symptoms of manganese deficiency, and there were no significant changes in measurements to manganese sprays.

Physiological And Biochemical

The present study was accomplished to find out the effects of salinity on germination, growth, physiological and biochemical processes of two different groundnuts (Arachis hypogaea L.), varieties viz., Dacca-1, and Zhinga groundnut. The experiments consisted of five salinity treatments viz., control (no salinity), 3, 6, 9, and 12dS/m during germination and vegetative stage of groundnut varieties. Results showed that germination percentage of both the groundnut varieties was significantly decreased with the increase of salt concentration. During the germination stage, maximum shoot and root length, shoot and root fresh weight and shoot and root dry weight of groundnut varieties were recorded from Zhinga groundnut variety at salt stress. The same result occurred during the vegetative stage of Dacca-1 variety while the Zhinga groundnut variety showed maximum parameters than Dacca-1. Fresh weight, as well as dry weight, of shoots and roots of both the groundnut varieties was also decreased with the increase of salt concentrations while leaf proline concentrations were increased among these varieties. Salinity caused significant (P<0.001) reduction in chlorophyll a, chlorophyll b, and total chlorophyll content in both the genotypes. Between two genotypes, Zhinga groundnut recorded higher chlorophyll a, chlorophyll b and total chlorophyll content than Dacca-1. From the studies, it is concluded that the groundnut genotype Zhinga was identified as the tolerant genotype to salt stress than Dacca-1. Overall results indicate that high salinity condition is not suitable for growing the groundnut.

The present study investigated the effects of salinity on the growth of groundnut (Arachis hypogaea L.), variety BARI Badam-8. The plants were grown in a series of plastic pots under controlled light and temperature conditions in the growth room. Salt (NaCl) solutions of different concentrations (0 mM, 50 mM, 100 mM, 150 mM, 200 mM, and 250 mM) were added to the pots, with three replicates. Results showed that shoot height, number of plants, main root length and lateral root length significantly decreased with the increase of salt concentrations. Fresh weight as well as dry weight of shoots and roots also decreased with the increase of salt concentrations while leaf proline and protein concentrations increased. Overall results indicate that high salinity condition is not suitable for growing groundnut. Journal of Bangladesh Academy of Sciences, Vol. 43, No. 1, 25-30, 2019

[THE EFFECT OF PLANTING DISTANCE AND WEDDING FREQUENCY ON GROWTH, YIELD OF PEANUT (Arachis hypogaea L) AND WEED POPULATION]. This study was aimed to determine planting distance and frequency of weeding which gives the highest growth and yield of peanuts. Peanut plants were planted in the Experimental Field of the Faculty of Agriculture, Bengkulu University from October to December 2018. The study was arranged in a Complete Randomized Block Design (RCBD) with 2 factors and 3 replications. The first factor is the planting distance of 40 cm x 20 cm; 40 cm x 30 cm and 40 cm x 40 cm. The second factor is the frequency of weeding consisting of no weeding, 1x weeding (age 2 WAP), 2x weeding (2 and 4 WAP), and 3x weeding (2, 4, and 6 WAP). The results showed that the interaction between the spacing of 40 cm x 40 cm and 2 x weeding can increase plant height. The spacing of 40 cm x 40 cm can reduce the population and dry weight of broadleaf weeds. The planting distance of 40 cm x 30 cm can increase the fresh weight of pods, pod weight/plot, and the highest dry weight of pods/plants. The frequency of weeding 2x can reduce the population and dry weight of broadleaf weeds; whereas weeding frequency 3x can reduce weed populations of grass and sedges- weeds, and dry weight of broadleaf weeds. The 3x weeding frequency can also increase the total number of pods/plants, pod weight/plot, and pod weight/plant.

Five rice varieties viz. Binadhan-4, Binadhan-5, Binadhan-6, Binadhan-10 and Iratom-24 were evaluated in vitro under different water stress conditions. Several parameters such as germination percentage, shoot length, root length, shoot-root ratio, fresh weight, dry weight, turgid weight, relative water content and proline accumulation were studied. Drought condition was created by MS medium supplemented with five treatments of PEG, with a control such as 0%, 1%, 2%, 3% and 4% of PEG. The highest germination (100%) was found in the variety Binadhan-10 under low water stress conditions induced by 1% PEG. Similarly, the highest percentage of germination was found in all varieties under control condition (0% PEG). The lowest percentage of germination was obtained in the variety Iratom-24. But under severe stress (4% PEG), the highest percentage of germination was found only in the variety Binadhan-10. Moreover, the variety Binadhan-10 was found to be the best at 4% PEG for shoot length, root length, shoot-root ratio, relative water content and also the best at 1% PEG for fresh weight, dry weight, turgid weight. Water stress decreased relative water content and increased proline accumulation in rice. The highest relative water content was recorded in the variety Binadhan-10 and the lowest value recorded in the variety Binadhan-5. The highest proline content was obtained from the binadhan-6 at the highest treatment (4% PEG). Binadhan-10 showed the best performance almost in all the parameters under drought stress because of its own nature of tolerancy.Progressive Agriculture 27 (2): 128-135, 2016

Abstract Silver nanoparticles (AgNPs) are presently the most commonly generated engineered nanomaterials and are found in a wide range of agro-commercial products. The present study was designed to synthesize AgNPs biologically using Ochradenus arabicus leaves and investigate their effect on the morphophysiological properties of Maerua oblongifolia raised in vitro. Physicochemical methods (ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy were performed for characterization and for obtaining microphotographs of the AgNPs. Shoots of M. oblongifolia (2–3 cm) grown in Murashige and Skoog medium supplemented with different concentrations of AgNPs (0, 10, 20, 30, 40, or 50 mg L−1) were used. Following 6 weeks of in vitro shoot regeneration, the shoot number, shoot length, leaf number, fresh weight, dry weight, chlorophyll content, total protein, proline level, and antioxidant enzyme activities of the plants were quantified. We found that 20 mg L−1 AgNPs increased the shoot number, shoot length, fresh weight, dry weight, and chlorophyll content of the plants. The maximum total protein was recorded in plants that were administered the lowest dose of AgNPs (10 mg L−1), while high concentrations of AgNPs (40 and 50 mg L−1) increased the levels of proline and the enzymes superoxide dismutase and catalase. Our results indicate that green-synthesized AgNPs may be of agricultural and medicinal interest owing to their effects on plants in vitro.
