Chickpea seed storage in different packagings, environments and periods

Abstract

Storage is a fundamental practice in the control of the physiological quality of seeds, as it is a method that can preserve their viability and vigor for a longer period. Thus, the objective of the present study was to evaluate the storage of chickpea seeds in different packagings, environments, and periods. The completely randomized design was used in a 2 × 2 × 4 factorial scheme, corresponding to two types of packaging (hermetic and Kraft® paper), two storage environments (cold chamber environment and conventional environment), and four storage periods (0, 45, 90, and 135 days), with four replicates. The seeds were placed in Kraft® paper bags and hermetic packagings and stored for 135 days in the environments: cold chamber (14.5 °C and relative air humidity of 65%) and conventional environment (no temperature and relative air humidity control). Every 45 days, seeds were subjected to the following evaluations: determination of water content, germination, first germination count and accelerated aging. In general, the maintenance of the physiological quality of chickpea seeds was verified in Kraft® paper packagings and the cold chamber environment. Storage of chickpea seeds in hermetic packaging must be carried out with seeds with 7% moisture, regardless of the storage environment. The packagings maintained the physiological quality of chickpea seeds for up to 45 days, regardless of the storage environment.

Impact of storage technologies and duration on insect pest population, post‐harvest losses, and seed quality of stored chickpea in Ethiopia

“…In contrast, the moisture content in the hermetic bags remained at safe storage levels throughout the entire 6‐month storage period. These findings align with previous studies that have demonstrated the effectiveness of hermetic bags in maintaining stable seed moisture content 14,15,18,36 . Similar results have been reported for other crops, such as green grams, where moisture content increased in PP and jute bags but remained consistent in hermetic bags over a 6‐month storage period 37 .…”

Understanding environmental factors during storage is crucial for making informed decisions and minimize quality losses 18 . Environmental variables such as temperature, RH, and seed moisture content should be considered during storage because unfavorable conditions could diminish seed lifetime 31 …”

“…Hermetic storage methods, such as Purdue Improved Crop Storage (PICS) bags, Super GrainPro (SGP) bags, and metal silos, have gained popularity due to their effectiveness and pesticide‐free nature 14–18 . These storage technologies create an airtight environment that inhibits insect and mold development through increased carbon dioxide levels and decreased oxygen content 19 .…”

[14][15][16][17][18] These storage technologies create an airtight environment that inhibits insect and mold development through increased carbon dioxide levels and decreased oxygen content. 19 Finding secure and efficient storage options to protect the quantity and quality of chickpeas at the smallholder farmer level is crucial, considering the significant volume of chickpeas produced, consumed, exported, and the overall storage losses caused by insect pests.…”

Alterações bioquímicas, fisiológicas e sanitárias em sementes de grão-de-bico (Cicer arietinum L.) durante o armazenamento

“…Nas nossas condições, as informações são ainda restritas, predominando o cultivo de grão-de-bico do tipo kabuli. Silva et al (2022), ao armazenarem sementes do tipo kabuli com 10,6% de umidade em sacos de papel e embalagem hermética sob condições não controladas de ambiente e câmara fria (14,5 ºC e 65% UR), observaram que a germinação das sementes decresceu linearmente em ambas as condições, independente da embalagem. A germinação inicial que era de 83% caiu para valores na faixa de 42% após 90 dias.…”
