Effects of rubber leaf litter vermicompost on earthworm population and yield of pineapple (Ananas comosus) in West Tripura, India

Purpose Rubber leaves are the abundant agro-waste and pineapple, the most economically important fruit crop in Tripura. So, in our present study, different amounts of rubber leaf vermicompost have been applied to the soils of pineapple plantation to determine their effects on earthworms—the soil ecosystem engineers, coupled with the vegetative growth and yield of pineapples. […]

Manurial value of khat waste vermicompost from Awday, Harar town, Ethiopia

Purpose Catha edulis, commonly called as khat or chat is an evergreen plant cultivated in Ethiopia for its stimulant leaves. The young leaves are chewed as a part of social recreation and the older leaves along with the twigs are discarded. This forms the major part of municipal solid waste that is dumped in large […]

Health risk assessment of textile effluent reuses as irrigation water in leafy vegetable Basella alba

Purpose The aim of this research was to assess the health risk of textile wastewater reuse as irrigation water on leafy vegetable (Basella alba) by comparing variable growth rate in different ration of wastewater and freshwater irrigation and assess their soil-to-plant transfer factor (TF) and health risk index (HRI). Methods Pot experiments were laid out […]

Nitrous oxide emissions from wetland soil amended with two types of cattle manure

Purpose The implications of increased applications of high quality cattle manure to agricultural systems in Africa on N2O emissions are still only partially understood. Methods A field experiment was carried out in a wetland in central Zimbabwe to determine the effects of cattle manure quality on emissions of N2O during the growing seasons of rape […]

The effect of oil palm decanter cake on the accumulation of nutrients and the stomatal opening of Solanum melongena (brinjal) plants

Purpose Research has shown that oil palm decanter cake (DC) serves as a potential source of nutrients for plant growth. This study therefore investigated the applicability of decanter cake (DC) as an amendment to soil for the growth of Solanum melongena (brinjal) at three ratios 10, 20, 30 % DC and suitable controls (0 %). […]

Effects of sugarcane pressmud on agronomical characteristics of hybrid cultivar of eggplant (Solanum melongena L.) under field conditions

Purpose The field experiments were conducted to utilize the sugarcane pressmud in the farming of Solanum melongena as an organic fertilizer. Methods For growing of S. melongena, six agricultural fields were selected for the six amendments of sugarcane pressmud, viz., 0 % (garden soil as control), 20 % (20 % sugarcane pressmud ? 80 % […]

Impact of textile sludge on the growth of red amaranth (Amaranthus gangeticus)

Purpose In Bangladesh, the sludge of textile effluent treatment plant has been considered as a potential environmental threat due to its huge volume and chemical content. Thus, the present study was carried out to assess the reuse possibility/potentiality of textile sludge in agricultural applications. Method Textile sludge was applied at different loading ratios (0–100 % […]

Anaerobically digested dairy fiber in soilless potting media for poinsettias

Purpose Sphagnum peat moss has been a primary component of soilless potting media for decades. Concerns over the sustainability of harvesting peat have fostered a search for renewable media components. Anaerobically digested dairy fiber (ADDF), a by-product of methane production, shows promise as an alternative to peat. Methods Poinsettias (Euphorbia pulcherrima ‘Classic Red’) were grown […]

Suitability of agricultural by-products as production medium for spore production by Beauveria bassiana HQ917687

Purpose The seemingly harmful effect of chemical insecticides to the environment, plants and human health, has led to prominent role of entomopathogenic fungi (ENPF) as biopesticide. However, the success of ENPF as biocontrol agent depends on their amenability to easy and cheap mass multiplication. Solid state fermentation (SSF) has emerged as an appropriate technology for […]
