Impacts of wheat seed storage at poor household level in Bangladesh

Small and marginal farmers have little access to improved seed from institutional sources and are thus largely excluded from the benefits of new varieties. The production and storage of improved varieties seeds at the household (HH) level can successfully overcome this problem. With this aim CSISA-CIMMYT (Cereal Systems Initiative for South Asia) project in Bangladesh have been working since 2012. Therefore, the study assessed the impacts of wheat seed storage systems at HH level, with a particular emphasis on how the poor farmers are benefited by doing the seed storage business. The study analyzed data and information collected at random from 210 supported and 60 non-supported farmers spread over three wheat growing districts namely Mymensingh, Faridpur and Rangpur. Wheat farmers used different storage containers and showed the highest level of satisfaction towards plastic sac along with poly bags and plastic/metal drum due to cost effectiveness and seed quality maintenance. On an average, supported and non-supported farmers retained respectively 103 kg and 100 kg of seed at household level, and sold most of their seeds to neighbouring farmers, local markets, and dealers. Wheat seed storage at household level was a profitable business to most of the respondent farmers. They could earn a reasonable net income (Tk.1127-Tk.1210) from seed storage. The farmers who stored seed in plastic/metal drum received the highest net income due to higher storage capacity, less storage cost, and higher seed price. The wheat storage program has created significant impacts in the study areas. A substantial increase was recorded in wheat area, wheat productivity, and financial benefit of the wheat farmers as a whole. Nevertheless, improved wheat seed is now available at farm level and most farmers become enthusiastic towards improved wheat cultivation because of this program. Respondent farmers did not face any critical problem during seed storage.Bangladesh J. Agril. Res. 43(2): 345-360, June 2018

The production and storage of improved varieties seeds at the household (HH) level can overcome this problem. The study assessed the wheat seed storage systems used at HH level, with a particular emphasis on how the farmers are financially benefited by doing the seed storage business. The study analyzed data collected at random from Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) project supported 210 farmers spread over three wheat growing Hubs namely Mymensingh, Faridpur and Rangpur. The study revealed that wheat growing farmers used different types of storage containers and showed the highest level of preference (score 7.2) on plastic/metal drum lining with polythene bag due to lower cost of storage, longevity, and seed quality maintenance. Wheat farmers retained on an average 95.7 kg of improved seed at household level. Majority of the retained seeds at HH level (64%) are being marketed and sold to neighbouring farmers, local markets, and dealers. Wheat seed storage at household level was a profitable business to most of the respondent farmers. They earned a reasonable net income (Tk.420-Tk.1471) from seed storage. The farmers who stored seed in plastic sac+poly bag received the highest net income (Tk.1471) due to less storage cost, and higher seed price.

The results of research on the study of two traditional and six technologies (options) with direct seeding of spring durum wheat bezenchukskaya Zolotistaya (soy precursor), on ordinary chernozem in 2017-2019 are presented. In the six-field crop rotation, it was found that when growing new varieties resistant to the main pathogens, against the background of direct seeding and improving the nitrogen supply of plants, the use of modern fungicides is justified only in years favorable for moisture, when the yield increase reaches 0.19 t/ha (5.9 %). On a natural background of fertility, additional costs for processing crops with fungicides are not recouped by increasing the yield. With traditional technology, treatment of crops with Soligor fungicide provides an average of three years increase in grain yield by 0.15 t / ha (7.9 %), net income of 308.1 rubles/ha (4.6%). The highest net income and profitability were revealed against the background of direct seeding and the use of ammonium nitrate – 8327.8-8532.0 rubles / ha and 70.7-80.7 %. Based on the research, when cultivating new varieties of spring durum wheat, it is recommended to introduce ammonium nitrate (N30) during the sowing period. When protecting plants-seed treatment, treatment of crops with herbicides and insecticides. The use of fungicides is rational to carry out in years favorable for moisture. Against the background of the use of biofungicide Phytosporin, the use of fungicides is not advisable.

Seed quality may be affected by several factors, including permeability, color, and lignin content in the seed coat. This study aimed at evaluating influence of lignin content in the tegument of seed samples of six different soybean cultivars, in which half of each sample was inoculated with the fungus Aspergillus flavus, on the physical and physiological quality, and on the seed health, during 180 days storage period, under cold chamber with controlled conditions of temperature and RH. For that, at each interval of 60 days, samples were removed, and the physiological quality of these seeds was assessed by means of moisture and lignin contents; and by tests of seed health, germination, and electrical conductivity. The moisture content of seeds remained constant during all storage period. In the seed health test, it was found that inoculation was efficient, once the minimum incidence of the fungus in the inoculated seeds was 85%. In the germination test, there was a trend of reduction on percentage germination with the increase in storage period. However, there was an increase on electrical conductivity of seeds assessed. It was concluded that there is no interference of the lignin content in the seed coat on the resistance to infection by the fungus Aspergillus flavus, even after seed storage for a period of 180 days.

ABSTRACT Information of seed quality during storage can be determined through the actual storage and storability vigor estimation. This study aimed at comparing effective accelerated aging method between physical and chemical, and studying the seed deterioration during storage in ambient (T =28-30 0C, RH=75-78%) and AC (T =18-20 0C, RH =51-60%) condition with three levels of initial moisture content (8-10%, 10-12%, and 12-14%) for 20 weeks. The final objective of this research was to develop model for storability vigor of papaya seed. Two experiments, accelerated aging and seed storage were conducted at Seed Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University from October 2015 to May 2016. A completely randomized design with nested factors and four replications was applied to both experiments. The results showed that physical accelerated aging using IPB 77-1 MMM machine was more effective than chemical accelerated aging using IPB 77-1 MM machine for papaya seed. The viability of seed stored in AC condition remained high until the end of the storage period, whereas it declined at 16 week storage period in the ambient condition. The viability of seed with initial moisture content of 12-14% declined faster than that of initial moisture content of 8-10% after 18 week storage periode. The model used to estimate the storability vigor of papaya seed accurately was the equation y = a + b expcx where y : storability vigor estimation, x : aging time and a,b,c : constant value. Simulation of storability vigor estimation with constant value of a, b, c and input of aging time can estimate storability seed vigor in actual storage.

The paper presents the results of research to assess the efficiency of winter wheat (Triticum aestivum L.) cultivation in adaptive crop rotations on typical chernozem. The crop yield have analyzed for three different crop rotations (grain-fallow, grain-grass-row, and grain-grass) in comparison with a monoculture on a stationary multifactorial field experiment on physical modeling of the farming system of the FSBSI “Kursk FARC” (Kursk region, Medvensky district). It was determined that the maximum yield was obtained in grain-and-row crop rotation; on average, over three years of research, the increase in it was 1.71 t/ha. Statistical data processing has carried out and correlations between the weather conditions of the year and the yield of winter wheat has revealed. Thus, a moderate direct relationship (r = 0.65) was established with atmospheric precipitation, and a moderate inverse relationship with the sum of effective temperatures (r = 0.58). Indicators of economic efficiency of winter wheat cultivation have calculated, both for monoculture and for three types of crop rotations. The lowest cost of winter wheat grain – 5926.94 t/ha – was recorded in grain-fallow crop rotation, which provided the highest net income of 12056.26 and the highest profitability among all options – 68.72%.

AbstractClimate change will alter rainfall patterns. The effect of rainfall during seed development and maturation on wheat (Triticum aestivum L.) seed quality (ability to germinate normally; air-dry longevity in hermetic storage at 40°C with c. 15% moisture content) was investigated in field experiments (2011, 2012) by providing rain shelter or simulating additional rainfall. High ability to germinate was detected from mid seed filling until after harvest maturity. Subsequent longevity was more sensitive to stage of development. It increased progressively, reaching maximum values during maturation drying at 53–56 days after anthesis (DAA), 5–11 (2011) or 8–14 (2012) days beyond mass maturity; maximal values were maintained thereafter in 2011; longevity declined with further delay to harvest in 2012. Post-anthesis protection from rain had no major effect: in later harvests longevity was slightly greater than the control in each year, but in 2011 wetting treatments were also superior to the control. Wetting ears at all stages of development reduced longevity immediately, but considerable recovery in subsequent longevity occurred when seeds re-dried in planta for several days. The greatest damage to longevity from ear wetting occurred with treatments at about 56 DAA, with poorest recovery at 70 DAA (i.e. around harvest maturity) in absolute terms but at 56–70 DAA relative to gross damage. Hence, seed quality in a strongly dormant wheat variety was resilient to rain. Net damage was greatest from rain late in maturation. The phase of seed quality improvement in planta was dynamic with deterioration also occurring then, but with net improvement overall.

AbstractSeed moisture content (SMC) is an important attribute to seed quality. Maintaining seed dryness throughout supply chain (The Dry Chain) prevents seed germination and quality losses. Ambient relative humidity (RH) and temperature affect seed moisture and thereof seed moisture isotherm. Present study was conducted to compare the moisture adsorption isotherms of wheat, maize, cotton and quinoa seeds packed in hermetic Super Bag and traditional packaging materials including paper, polypropylene (PP), jute and cloth bags. Seeds were incubated at 60, 70, 80 and 90% static RH. Nearly straight line moisture isotherms for all crop seeds were obtained in Super Bag. Seed moisture contents increased in traditional packaging materials with increasing RH. At higher level of RH, moisture contents increased slightly (1-2%) in Super Bag, whereas this increase was much higher in traditional packaging materials (≈9% higher than original SMC at 90% RH). In second study, seeds were dried to 8 and 14% initial seed moisture contents using zeolite drying beads and were stored in hermetic and traditional bags for a period of 18 months. For all crop seeds, germination was severely affected in all packaging materials both at 8 and 14% initial SMC except storage in Super Bag at 8% SMC. Wheat seed stored in Super Bag at 8% SMC almost maintained initial germination while germination of cotton, maize and quinoa seeds declined 7%, 14% and 30% respectively in Super Bag at 8% SMC. Seed storage in Super Bag can help to prevent the significant increase in seed moisture at higher RH as is evident from moisture isotherm study, thus helps to preserve quality of maize, wheat, cotton and quinoa seeds by maintaining The Dry Chain throughout the storage period.
