growth stages are crucial for loss in yield of Groundnut varieties, but tolerant genotypes may
give significant yield due to maintenance of physiological responses that were triggered during
drought. In Perambalur district, On Farm Testing (OFT) was conducted by ICAR-Krishi
Vigyan Kendra, Perambalur, Tamil Nadu, to assess suitable drought tolerant and high yielding
Groundnut variety in terms of yield, acceptability and adoption potential during rabi 2020-21.
The study revealed that Dharani recorded higher pod yield (2402 kg ha -1 ), high number of pods
plant -1 (26) and optimum Plant population (26.3 plants m -2 ) as compared to farmers practice.
The groundnut variety Dharani resulted in the highest shelling percentage (75%), while the
lowest was registered with TMV 7 (71%). The Gross and Net returns were Rs. 1, 15,324 and
Rs. 66,593 ha-1 respectively by cultivating Dharani as against Rs. 87, 523 and 41, 550 ha -1 in
the check variety. Groundnut variety Dharani would be a better option for rainfed cultivation
in Perambalur district of Tamil Nadu.

Eco-Friendly Management of White Grub a Devastating Insect Pest of
Rainfed Agro- Ecosystem in Uttarakhand Hills

The Agriculture in the north western Indian Himalayan Hilly region is being practiced mostly
by the marginal and resource poor farmers and they face several biotic and abiotic stresses due
to the fragile ecosystem and harsh climatic conditions. In north western Himalaya majority of
areas comes under rainfed condition and cropped areas is under well drained sandy soil along
hill slopes which is favourable for growth and development of white grubs so the white grub is
a major challenge in rainfed agriculture. White grubs are polyphagous insect with cosmopolitan
nature. A grub is the larval stage of scarab beetle. More than 75 species of white grub have
been recorded in Uttarakhand but Anomala dimidiata, Holotrichia longipennis and Holotrichia
seticollis have been reported as the dominant white grub species in this state. The grub damages
the root of many cultivated field and vegetable crops, whereas their adult beetles cause severe
defoliation of many fruit and forest trees. The damage caused by the grub under rainfed
conditions may vary on an average 10-30 % to sometime complete crop failure. Several
insecticides are recommended for the control of white grub, but in fact the insecticide does not
satisfactory control unless used in very high doses, which in turn become hazardous and
uneconomical besides being unsustainable. The adult beetles are attracted towards light, hence
light traps were found to be effective tool for trapping of adult of white grub so ICAR-
Vivekanand Patvatiya Krishi Anusandhan Sansthan, Almora designed and developed VL
White Grub Beetle Trap -1. This technology is low cost, ecofriendly and provides long term
integrated insect pest management. Therefore, this ecofriendly novel technology was
