Proper germination and proper growth of seedlings in conventional farming methods are often not achieved at the desired rate. The purpose of priming is to reduce germination time and improve stand and percentage of germination and increases vigour for fast and strong plant development. In order to evaluate the effect of seed priming on growth and yield of wheat the present study was conducted at Agronomy Farm House, Rajshahi University. Three wheat varieties (BARI Gom-24, BARI Gom-25 and BARI Gom-26) were tested with three groups of priming media (osmo-priming, thermos-priming and plant growth regulator priming) and control (non-soaked). Seeds were primed for 24 h at 25°C with four priming media, osmo-priming (1% NaCl, 2% KNO3, 2% KH2PO4, and 10% PEG), PEG-Priming (50 μM GA3 and 50 μM BAP) and thermo-priming (0°C, 5°C and 10°C) and control was without priming agent. All types of priming media were significantly different among their types for plant height (cm), tiller number and dry biomass (g). PEG was significantly different in osmo-priming, GA3 was significantly different in PGR-priming and 0°C was significantly different in thermo-priming. In case of vigor index, 2% KH2PO4 was suitable among osmo-priming, GA3 was better than BAP priming and 0°C was optimum among all temperature priming. Seed priming helps seeds to grow rapidly and evenly in the field, producing healthier and faster maturing crops with better yields. J. Bio-Sci. 29(2): 111-122, 2021 (December)

Plastic Carbon

Polystyrene (PS) is one of the major plastics contributing to environmental pollution with its durability and resistance to biodegradation. Recent research has found mealworms ( Tenebrio molitor) and superworms ( Zophobas morio) to be able to utilize PS as a carbon food source and degrade them without toxic effects. In this study, the effects of food additives on plastic consumption augmentation were studied, with small additions of sucrose and bran found to increase PS consumption. To close the plastic carbon cycle, we also evaluated the use of worm frass for dragon fruit cacti ( Hylocereus undatus) growth and found that superworm frass supported rooting and growth better than mealworm frass and control media over a fortnight. Superworms, apart from being known fish and poultry feed, have been shown to be a suitable natural solution to the PS plastic problem that can support plant growth towards a zero-waste sustainable bioremediation cycle.

In the sub-tropical regions of India, the 1st to 3rd week of November is the optimum time for sowing wheat. A delay in sowing due to various factors causes a substantial yield reduction. Seeds of four wheat varieties (Sonak, UP 2338, Raj 3765 and PBW 343) were subjected to seed priming treatments involving water, salts, growth regulator and the sowing of sprouted seed under late-sown conditions during the winter seasons of 1998-99 and 1999-2000. The sowing of sprouted seeds resulted in significantly more rapid emergence of seedlings, accompanied by higher grain and straw yields. Seeds primed with IAA, KCl, water, ZnSO4 and Na2SO4 followed in this order. The lowest seedling emergence and grain yield were obtained for unprimed seeds. Seedling emergence was higher in the variety Sonak, while Raj 3765 and UP 2338 had higher leaf water, osmotic and turgor potentials during the 1998-99 season. The variety PBW 343 produced significantly higher grain and straw yields in the 1999-2000 season.

This study elucidates an attempt to prepare compost from kitchen, dairy and drainage wastes and estimate their manorial value, and to examine the effect of prepared compost on the properties of post-harvest soil. The composts on individual item were prepared by the recently practiced quick composting method. The composts were applied in four different plots; three were treated with composts and the rest with no-treatment. The red amaranth was taken as the reference crop for the present study. The plots treated with dairy and kitchen wastes composts conserved the maximum soil moisture, available phosphorus and exchangeable potassium. The compost prepared from dairy wastes showed the best performance in conserving soil organic carbon and organic matter. The kitchen wastes compost supplied the maximum amount of nitrogen content to the soil. The dairy and kitchen wastes compost was better than the drainage wastes compost for sustainable crop production and in improving soil chemical properties and maintaining good soil quality. Dairy wastes compost showed the best performance in terms of canopy developing the plant height and root length. The highest yield was found in dairy and kitchen wastes compost treated plots. For growth and yield of red amaranth, dairy, kitchen and drainage wastes compost were superior to conventional farming as sustainable agricultural inputs.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16872 Progress.

Effects of two types of biochars from wheat straw (SB) and hard miscellaneous woods (WB), combined with two types of soils on the growth and yield of wheat were evaluated to identify biochar addition to suitable soils on crop yield for accelerating biochar application. Plant growth variables and yields were studied in order to assess the agronomic efficiency of biochar. Our results showed that both biochar additions to an alkaline soil had little or negative effect on plant growth and wheat yield. However, to neutral soil, addition of both biochars could improve plant growth and increase significantly the wheat yield. There were significant differences on effective spikelet, number of seeds, above ground biomass and no significant differences on total spikelet, TKW among different treatments which SB was applied in neutral soil, whereas there were no significant differences on any aforementioned index at application of WB in neutral soil. Further analysis indicated that effect of SB on yield was better than that of WB, and 6% SB and 2% WB were the best for neutral soil respectively.

A field study was conducted to evaluate the effect of different plant growth regulators (PGRs) applied through seed priming and foliar spray on growth and yield of three okra cultivars grown under calcareous soils. The cultivars of Punjab Selection and Sabzpari produced significantly higher number of branches and leaves per plant, pod length and diameter and pod yield as compared to cv. Green ferry, while, cv. Punjab selection produced significantly greater number of flowers and pods per plant as compared to other two cultivars. Seed germination (%), plant height, and fruit set (%) were not affected by the cultivars. Among the PGR treatments, seed primed with GA3 resulted in significantly higher germination percentage and greater plant height at flowering. Seed priming and foliar spray with NAA and GA3 were effective in increasing the final plant height, number of branches, number of leaves, number of flowers and number of pods per plant and fruit set (%), fresh weight per pod and pod yield. However, pod diameter, pod moisture content and dry weight per pod were not influenced by the PGR treatments applied. These results suggested that the PGRs have great potential to improve seed germination, enhance growth and increase yield of okra cultivars under calcareous soils.

A field experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University, Dhaka during November 2012 to April 2013 to evaluate the influence of variety and sowing date on grain growth and yield of wheat. The experiment consisted of four wheat variety viz., BARI Gom-21, BARI Gom-24, BARI Gom-25 and BARI Gom-26 and three sowing date viz., 20 November, 01December and 12 December. Grain growth, yield contributing characters and yield of wheat were significantly influenced by different variety and sowing date. Among the variety, BARI Gom-24 and BARI Gom-25 showed initial lower lag phase duration of 8 days after anthesis (DAA) and 12 DAA, respectively than BARI Gom-21 (16 DAA) sown at 01 December. The maximum grain growth rate whole over the period was maintained by BARI Gom-26 sown at 01 December. It reached peak at 20 DAA (1.17 mg /grain/day). The minimum growth rate was maintained by BARI Gom-21 and BARI Gom-24 sown at 12 December (0.15 mg /grain/day). BARI Gom-25 sown at 01December gave the highest yield (4.6 t ha?1) whereas BARI Gom-21 sown at 20 November gave the lowest (2.67 t ha?1). All the wheat varieties sown at 01 December yielded better than 20 November and 12 December sowing.Bangladesh Agron. J. 2015, 18(2): 97-104
