In Cambodia, cassava is mostly grown with little or no fertilizer inputs, but the magnitudes of nutrient balances are not known. This study was conducted to assess nutrient balances for cassava cultivation in Kampong Cham province in Northeast Cambodia. Forty five households in four cassava production zones were interviewed in relation to their cultural practices and crop residue management...

Agricultural intensification, or the increase in crop production per unit of input land area to meet needs a growing population, has resulted landscape dominated by large scale monoculture cropping. Pollinators, specifically, are impacted lack diverse floral and habitat resources associated with this type farming. Agriculture must develop practices that diversify availability flowering support ...

Suggested citation IARI (2012) Crop residues management with conservation agriculture: Potential, constraints and policy needs. Indian Foreword India being an agriculture-dominant country produces more than 500 million tons of crop residues annually. These residues are used as animal feed, for thatching of homes, and as a source of domestic and industrial fuel. A large portion of unused crop re...

Little is known about management practices that can simultaneously improve soil and environmental quality and sustain crop yields. The effects of novel and traditional management practices that included a combination of tillage, crop rotation, and N fertilization on soil C and N, global warming potential (GWP), greenhouse gas intensity (GHGI), and malt barley (Hordeum vulgarie L.) yield and qua...

The paper investigates the value of using distinct vegetation indices to quantify and characterize agricultural crop characteristics at different growth stages. Research was conducted on four crops (corn, soybean, wheat, and canola) over eight years grown under different tillage practices and nitrogen management practices that varied rate and timing. Six different vegetation indices were found ...

Cassava (Manihot esculenta Crantz) is currently the most important upland crop of Cambodia, but information on yield variations and causal factors which is important for efficiently targeting efforts to increase production is still lacking. The objectives of this study were to determine the yield variations and causal factors for cassava production in Kampong Cham province in Cambodia. Fort...

Objectives The objective of this research is to characterize biological, physical and chemical soil quality parameters and monitor their changes over time in minimum tillage and no-till seeding systems as affected by tillage, crop species and management systems to identify soil quality attributes that can be used in the development of best management practices for conserving soil quality and en...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

This paper presents a number of applied management practices, based on data and research, necessary for dairies in the western United States to produce, store and fed high quality corn silage. These management practices include hybrid selection, growing a quality crop, proper harvest timing, chopping, packing, inoculating and feed out of the stored corn silage.
