The agricultural scenario in Rural India presents a very intricate picture of role of women in farming activities. The present study was conducted in district Churu of Rajasthan. Total sample consisted of 300 rural women from 12 villages of 3 panchayat samities of district Churu. Result shows that out of 10 farming activities, extent of participation of rural women was noticed ‘high’ i.e. more than 80% in 4 farming activities i.e. cleaning of field, seed selection and cleaning, intercultural operations and harvesting. ‘low’ in 3 farming activities i.e. manure application, irrigation, and pesticide application whereas ‘nil’ in 3 activities i.e. ploughing, fertilizer application and seed treatment and sowing. Farming activities like cleaning of fields, seed selection and harvesting were the items of maximum participation while manure and pesticide application activities were the items of least participation in all the 3 age groups i.e. younger, middle and older. SES was measured in 3 parameters viz. low, medium and high. High SES respondents participated very poorly for all the farming activities but a little better they participated for seed selection. In medium SES, participated was noticed maximum for seed selection and harvesting i.e. 44.2 and 46.4 percent respectively, while lowest for manure application i.e. 2 (28.5). Respondents of low SES participated to their maximum i.e. 142 for 4 farming activities viz. cleaning of field, seed selection, inter- cultural operations and harvesting with their respective percentage 51.4, 47.9, 54.8 and 50.3. It is well analyzed from the results that the farming activities like seed selection was the item of maximum participation whereas, 2 farming activities i.e. manure and pesticides application were the item of least participation in all the age groups as well as all SES categories.

Rot Disease

Seed treatment of soybean with <i>Bndyrhizobium japonicum, Trichoderma harzianum, T. viride, T. hamatum, T. koningii</i> and <i>T. pseudokoningii</i> significantly controlled the infection of 30-day-old seedlingsby <i>Maerophomina phaseolina, Rhizoctonia solani</i> and <i>Fusarium</i> spp. In 60-day-old plants <i>Trichoderma</i> spp.. and <i>B. japonicum</i> inhibited the grouth of <i>R. solani</i> and <i>Fusarium</i> spp., whereas the use of <i>B. japonicum</i> (TAL-102) with <i>T. harzianum. T. viride, T. koningii</i> and <i>T. pseudokoningii</i> controlled the infection by <i>M. phaseolina. Greater grain yield was recorded when B. <i>japonium</i> (TAI-102) was used with <i>T. hamatum</i>.

Soybean aphid, Aphis glycines Matsumura, remains the key insect pest of soybean, Glycine max (L.) Merrill, in the north-central United States. Management of this pest has relied primarily on scouting and application of foliar insecticides based on an economic threshold (ET) of 250 aphids per plant. This review explains why this ET remains valid for soybean aphid management, despite changes in crop value and input costs. In particular, we review how soybean aphid impacts soybean yield, the role of biology and economics in recommendations for soybean aphid management, and the short- and long-term consequences of inappropriately timed insecticide applications.

Endogenous Aba

The effect of drought stress and abscisic acid (ABA) applied at tillering stage (55 days after sowing) was compared in 2 wheat cultivars differing in drought tolerance. The activities of superoxide dismutase (SOD) and peroxidase (POD) and contents of endogenous ABA in plants were measured at 3 days of drought stress in cv. Chakwal-97 (drought tolerant) and cv. Punjab-96 (drought susceptible). ABA was applied at 10<sup>&ndash;6</sup> mol/L as presowing seed treatment for 18 h. Drought tolerant cultivar has a more efficient mechanism to scavenge reactive oxygen species as shown by a significant increase in the activity of antioxidant enzyme SOD. Under drought stress, ABA significantly increased the activities of SOD and POD, showing a significant decline on rewatering. The relative water content was significantly increased by ABA priming under drought stress in both wheat cultivars. The sensitive cultivar exhibiting lower endogenous ABA content was more responsive to ABA priming. On rewatering, the magnitude of recovery from drought stress was greater in tolerant cultivar. ABA was highly effective in improving grain weight of tolerant cultivar under drought stress. &nbsp;
