Naveen, Baibhav and Local sickles were evaluated for harvesting paddy crop with 20 farm women age 30-50 years (Subjects) at surrounding villages of KVK, Chatra, Jharkhand. The data of improved and Local sickles were compared. During the harvesting session, they spend nearly 7-8 hours daily to perform the activity. The Naveen sickle was the heaviest weight 229g followed by Baibhav and deshi was ...

Agricultural soils are at risk of nitrogen (N) leaching especially during the fallow period in autumn and winter. Cover crops grown to capture soil mineral N that otherwise would leach groundwater. They can serve as green manure providing cash crop spring. We investigated whether mixing species cover enhance therefore reduce more effectively than pure stands without increasing hypothesised mixe...

The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...

In 1987, the United States Department of Agriculture (USDA-ARS) National Sedimentation Laboratory, in cooper­ ation with the Mississippi Agricultural and Forestry Experi­ ment Station (MAFES) and the Natural Resources Conservation Service (NRCS), initiated an interdisciplinary research project to develop profitable and environmentally sustainable conservation production systems for silty upland...

 In order to evaluate the effects of cover crops on reduced weed biomass in hybrid sunflower an experiment was carried in the research stations, Natural Resources Medicinal Plants (Samian_Ardabile) with 3 replicates in 1390-1391. The first factor was considered three type of cover crops, winter rye, spring barley, winter wheat with 2 control treatment, second factor was mulch management at two ...

field trials were conducted at the experimental station (brody) belonging to poznan university of life sciences (ne poland). the purpose was to evaluate the impact of different tillage systems and white mustard cover crop on soil enzymatic activity and severity of plant infection by pathogenic fungi in spring wheat. a randomized complete block design was set up with four replicates per treatmen...

Canopy characterization is essential for describing the interaction of a crop with its environment. The goal of this work was to determine the relationship between leaf area index (LAI) and ground cover (GC) in a grass, a legume and a crucifer crop, and to assess the feasibility of using these relationships as well as LAI-2000 readings to estimate LAI. Twelve plots were sown with either barley ...

This paper describes a modification of the Wassermann test giving an improved standardization of the complement titration and of the haemolytic system which is suitable to the resources of a small laboratory. Advantage has been taken of the stability of complement preserved by the method of Richardson (1941), so that modern methods for the standardization of the haemolytic system can be include...
