In no-tillage areas, cover crops are a continuous supply of organic matter and other positive improvements to the soil’s structural quality. We evaluated soil physical attributes in area cultivated with brassica on residues under no-tillage. Six coverages [1-Brachiaria (B), 2-Sunn hemp (S), 3-Pearl millet (M), 4-S + B; 5-B M; 6-S M] native (Cerrado biome), were for resistance penetration (RP), ...
Ethiopia is remarkably rich in its biological, ecological and landscape diversity and is home to outstanding natural bio-resources such as a number of herbs, aromatic and medicinal plants. The present study was carried out to study the composition, distribution and economic importance of insect pests of prioritized aromatic (Mentha sp., lemon verbena, fennel, rosemary, rosadamascene, oregano, p...
This paper presents a system for detection and recognition of pests in stored-grain based on video analysis. Unlike current systems which conduct analysis of static images, the proposed system uses video data captured by camera and performs video analysis to detect and recognize pests in grain. By using video data instead of static images, techniques such as motion estimation and multiple-frame...

Sweetpotato (Ipomoeae batatas (L.) Lam.) is an important food crop affected by several pests throughout the world, especially in tropical, subtropical, and temperate regions. Although Japan is relatively free from many serious sweetpotato pests, some pests, especially soil-borne pathogens, viruses, and insects such as plant-parasitic nematodes and weevils, cause severe damage in Japan. In this ...
A Tnt1-insertion mutant population of Medicago truncatula ecotype R108 was screened for defects in nodulation and symbiotic nitrogen fixation. Primary screening of 9,300 mutant lines yielded 317 lines with putative defects in nodule development and/or nitrogen fixation. Of these, 230 lines were rescreened, and 156 lines were confirmed with defective symbiotic nitrogen fixation. Mutants were sor...
The efficient use of green manure enhances sustainable nitrogen (N) cycling in agroecosystems. Appropriately utilizing the differences N and fiber between cultivars or harvesting times strengthens efficiency for subsequent crops. Therefore, it is necessary to clarify these differences. We clarified fibers from four sunn hemp (Crotalaria juncea L.) commercial at two after spring summer seeding t...
The field investigation during 2013-14 at Talwandi sabo, Punjab revealed that there are 19 insect pests identified from kharif crops whereas 13 insect pests were recorded from rabi crops. The 5 bio control agents and 2 ant species were recorded from agriculture field. In these Hemiptera and Lepidoptera are having maximum number of insect pests causing major damage to both kharif and rabi crops....
Interactions between plants and insect herbivores are important determinants of plant productivity in managed and natural vegetation. In response to attack, plants have evolved a range of defenses to reduce the threat of injury and loss of productivity. Crop losses from damage caused by arthropod pests can exceed 15% annually. Crop domestication and selection for improved yield and quality can ...
