The salient findings of the present experiment have been summarized; Groundnut crop is highly susceptible to weed infestation because of its slow growth in the initial stages up to 40 days, short plant height and underground pod bearing habit. Groundnut-weeds comprise diverse plant species from grasses to broad-leaf weeds and sedges, and cause substantial yield losses (15-75%). Weeds affect groundnut through the production of harmful allelochemicals. Thus, weed control is the foremost critical production factor in groundnut cultivation. Herbicides were found to be selective in controlling many weeds in monocropping as well as in cropping systems. Herbicides, though, selective, efficient and cost effective weed control measure in controlling weeds in groundnut, the maximum benefit can be achieved by combining herbicides with manual, cultural and mechanical weed control methods. These methods of weed control also vary with the groundnut growing situation and the cropping systems. In this review, an effort was made to compile the information on feasible weed management practices for groundnut in India and the future strategies to very simple, cheap, effective, and environmentally safe integrated approaches.

The target of doubling farmer’s income in a short period requires identification of sources of income growth and enabling conditions for harnessing their growth potential. The pathway for doubling of farmer’s income encompasses several dimensions, from production to post-harvest management. Chickpea, pigeonpea, urdbean, mungbean, lentil, fieldpea, cowpea and lathyrus are the major pulse crops grown in the country. Pulses contributes immensely towards doubling farmer’s income through diminishing cost of production, scaling per unit productivity, efficient marketing networks, increased minimum support price and post harvest value addition.

Ambedkar University Rehti, (Village Bordi) Tehsil- Nasrullaganj, Distt- Sehore (M.P.) during Rabi, 2018-19 and 2019- 20. Out of ten varieties of chilli screened against sucking pests (Aphids and Mites) of chilli, none of the varieties was found completely free from the attack of Aphids and mites. The varieties, VNR-277 and VNR- 577 were ranked least susceptible, while Pusa Jwala and US-1003 as highly susceptible and US- 9009, MHCP-310, MHCP-317, US-7030, VNR-1921, and VNR-109 as moderately susceptible. The minimum leaf curling percent was also recorded in the least susceptible varieties, VNR-277, followed by VNR-577 and maximum was in highly susceptible varieties, Pusa Jwala and US-1003. Rest of the varieties viz., US-9009, MHCP-310, MHCP-317, US-7030, VNR-1921 and VNR-109 were moderately ...

The highest grain yield (kg./ha.) was recorded in Quinalphos 25 EC (950) and it was minimum in Chlorpyriphos 20 EC(940). The best cost benefit ratio was noted in Quinalphos 25 EC (1:1.94) followed by Chlorpyriphos 20 EC (1:1.92)), and lowest in Alphamethrin 10 EC. (1:1.91).

The recommended agronomical practices were adopted properly. Each treatment was prepared for alternate use of two insecticides during six sprays. The spraying was done at 10 days interval with 500 litre water per hectare, sprayed by knapsack sprayer fitted with a duromist nozzle. These treatments were marked as T 1- Imidacloprid (70%WG) @ 24.5 gai/ha & Oxydmeton methyl (25%EC) @ 250 gai/ha, T 2- Thiaclorprid (21.7%SC) @ 30 gai/ha & Dimethoate (30%EC) @ 250 gai/ha, T 3- Imidacloprid (17.8%SL) @ 25 gai/ha & Acephate (75%SP) @ 250 gai/ha, T 4- Imidacloprid (30.5%SC) @ 26.25 gai/ha & Thiamethoxam (25%WG) @ 37.5 gai/ha, T 5- Spiromesifen (22.9%SC) @ 144 gai/ha & Deltamethrin (2.8%EC) @ 15 gai/ha, T 6-Fipronil (5%SC) @ 100 gai/ha & Lambdacyhalothrin (4.9%EC) @ 15 gai/ha, T 7-Acetamiprid (20%SP) @ 30 gai/ha & Difenthiuran (50%WP) @ 300 gai/ha and T 8-Untreated check. Except third spray, in all the sprays T5 reduced maximum thrips population and found at par with T6. The highest population reduction was also noted in T5 (77.78%) followed by T6-(76.94%). The population of whitefly was lowest after each spray in T2-and showed no significant difference with T3 except in 6 th spray. The similar trend was observed in population reduction also in T2 (76.69%) and T3 (72.20%).

Both industrial and food crops as well as forest trees are attacked by termite. Reports on economic losses caused by termite infestations have been made worldwide. The objective was to identify suitable and sustainable indigenous methods adopted by resource poor farmers for termite control. Semistructured questionnaires were administered to 20 farmers in each of the selected communities who practiced indigenous termite control methods. A total of 100 farmers were interviewed, who had applied various indigenous treatments on their crop fields against termite infestation. The study recorded a total of 24 termite species, which varied in presence at each locality, with a few serious pest species damaging agricultural products such as maize, yam, millet, and other natural resources in the area. Five termite prevention and control methods were identified: (i) burial of plant and animal materials, (ii) ap...
