| dc.description.abstract | The chickpea, Cicer arietinum (L.) is having vital role in the diet of people and stands first in area and production in the country and plays an important role in the agricultural economy of India. Use of quality seed is the basic input in crop production. After harvest, the seeds have to be stored for different periods before these are actually used for sowing in the next season. Under normal storage conditions, chickpea is damaged by a bruchid viz. Callosobruchus chinensis (L.) upto a great extent. Synthetic organic chemicals are used to protect stored pulses and found effective in controlling the pest but having toxic effect to grain and human beings. This has led to diversity the control measures that should be non-toxic and effective approach against the pulse beetle, Callosobruchus chinensis (L.). The present investigations were carried out to study the efficacy of grain protectants i.e. neem seed kernel powder @ 20 g/kg, neem oil @ 10 ml/kg, Mustard oil @ 7.5ml/kg, groundnut oil @ 7.5 ml/kg, turmeric powder @ 3.5 g/kg mustard oil + turmeric powder @ 3.75 ml + 1.75g/kg, groundnut oil + turmeric powder @ 3.75ml+1.75g/kg, saw dust (7cm covering) sand (7cm covering), dung cake ash (7cm covering) and wheat husk (7cm covering) against C. chinensis and their effect on germination of chickpea seeds (var. HC-3). There were a total of 12 treatments and each treatment was replicated thrice including untreated seeds as control and kept in plastic as well as glass jars under ambient storage conditions. All the oils and dung cake ash gave significantly higher adult pulse beetle mortality as compared to untreated control. On the basis of number of eggs laid, adult emergence and seed damage saw dust, sand and dung cake ash (7cm covering each) were considered as most effective against C. chinensis. None of the grain protectant treatments had an adverse effect on germination and vigour index except oils and mixture of oils with turmeric powder which slightly hampered the standard germination of chickpea seeds. | en_US |
