The experiment on efficacy of methoxyfenozide 24 SC on leaf miner, Aproaerema modicella and its effects on coccinellids was conducted during kharif 2012 and rabi 2013 on groundnut variety, VRI 1. Among different doses of methoxyfenozide 24 SC (180, 210 and 240 g a.i/ha), chlorpyriphos 20 EC@225 g a.i/ha, lamda cyhalothrin 5 EC@15 g a.i/ha and dichlorvos 76 SC@750 g a.i/ha, the significant least incidence of Aproaerema modicella was recorded in methoxyfenozide @240ga.i./ha(4.8%/plants) followed by methoxyfenozide@210 g a.i./ha (5.6%/plants) and methoxyfenozide@180 g a.i./ha (7.2%/ plants). Maximum population of coccinellids was recorded in the untreated check (3.4 nos./plant) followed by methoxyfenozide@180 g a.i./ha (2.9nos./plant),methoxyfenozide@210 g a.i./ha (2.8 nos./plant) and methoxyfenozide@240 g a.i./ha (2.7nos./plant).High pod yield was recorded in the plots treated with methoxyfenozide@240 g a.i./ha (3704.5 kg/ha) followed by methoxyfenozide@210 ga.i./ha (3559.5 kg/ha) and methoxyfenozide @180ga.i./ha (3441.5 kg/ha).

Field experiments with foliar application of calcium silicate @ 2.0, 3.5 and 5.0 per cent, soil drenching of calcium silicate @ 10.0, 15.0 and 20.0 per cent and combination of foliar and soil drenching (@ 2.0% + 20.0%, 3.5% + 15.0% and 5.0% + 10.0%) were evaluated on 20 days old groundnut plant and compared with an untreated check. Application of calcium silicate via foliage and soil simultaneously @ 5 and 10 per cent on 20 days after dibbling of groundnut was effective to reduce the population of leaf miner and their leaflet damage, recording mean population of 5.25 nos. of larvae/10 plants and 16.46 per cent leaflet damage, respectively, while it was 12.25 nos. of larvae/10 plants and 27.95 per cent leaflet damage in untreated control. Reduction in population of leaf miner in groundnut might be due to silica induced plant defensive enzymes, however, the moderate reduction in population of leaf miner pest in groundnut can be well explained due to the high accumulation of silica in groundnut plants.

Abstract Two virginia-type peanut (Arachis hypogaea L.) cultivars, NC 6 and NC 7, were observed to germinate slowly under field conditions. Three seed treatments (1%, 5%, and 10%) of ethrel, cis-N-((1,1,2,2-tetrachloroethyl)thio)4-cyclo-hexene-1,2-dicarboximide, were prepared with a recommended seed treatment (45% Difolitan and 25% PCNB) and dusted on the seed. The experimental design was a 2 (cultivars) × 4 (3 ethrel treatments and an untreated check) factorial in a randomized complete block with four replications. The experiment was conducted for 2 years (1980 & 1981) at two locations (Suffolk, VA, and Beltsville, MD). Factors studied were: Stand counts (10 and 14 days after planting), plant dry weight (18 and 42 days after planting), pod yield, grams/100 seed, and percentages of meat, total sound mature kernels, extra large kernels, and fancy pods. No significant differences were found among ethrel treatments for any factor, except stand counts. Plots planted with ethrel-treated seed had significantly higher stand counts at 10 and 14 days than plots not planted with ethrel-treated seed. Significant differences occurred between locations for all factors, and between years for all factors, except stand counts at 14 days and grams/100 seed. Significant differences occurred between cultivars for all factors, except plant dry weight at 18 days, pod yield, and percentage of fancy pods. These results indicate that, while stands may be improved with ethrel-treated seed, no significant effects on yield or grade factors were found.

The application of wastes from the wine-distillery industry as source of organic matter and nutrients could be a good option of agricultural management. This study is focused on soil nitrogen (N) mineralisation after addition of compost derived from this industry at different doses (7, 13 and 20 t ha–1). An aerobic soil incubation in controlled conditions was carried out to study N mineralisation from the soil-compost mixture as well as isolating the compost from the soil. The data were fitted to a non-linear regression obtaining low values of potentially mineralisable N (N0) and constants of mineralisation (k) (from 81 to 104 mg kg–1 and from 0.008 to 0.013 L day–1 for the soil-compost mixtures, and from 42 to 71 mg kg–1 and from 0.009 to 0.015 L day–1 for the increasing doses of compost) which indicates that it is a mature compost very resistant to mineralisation. Nitrogen mineralised (NM) in the field during two growing seasons (2011 and 2012) of a melon crop was calculated through a N balance, taking into account N inputs and outputs in the soil-plant system. NM in the unamended plots accounted to 31 kg ha–1 and 24 kg ha–1 in 2011 and 2012, respectively, and increased proportionally to the dose of compost applied until 113 kg ha–1 and 98 kg/ha in the consecutive years. The constants of mineralisation obtained in the laboratory were adjusted by field temperatures to predict NM in the field and a general overestimation was observed. The best estimates were obtained when considering the mixture of soil and compost, which reflects the important role of the soil to evaluate N mineralisation caused by the addition of organic wastes.
