The overarching goal of this research was to develop and demonstrate an automated Cropland Classification Algorithm (ACCA) that will rapidly, routinely, and accurately classify agricultural cropland extent, areas, and characteristics (e.g., irrigated vs. rainfed) over large areas such as a country or a region through combination of multi-sensor remote sensing and secondary data. In this researc...

water deficit is an important factor limiting crop growth all over the world. in order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. the experiments were carried out at the agricu...

poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...

Organic farming provides many benefits in Indonesia: it can improve soil quality, food quality and soil carbon sequestration. This study was designed to compare soil carbon sequestration levels between conventional and organic rice farming fields in west Java, Indonesia. The results from soil analysis indicate that organic farming leads to soil with significantly higher soil carbon storage capa...

Effective weather forecast information helps smallholder farmers improve their adaptation to climate uncertainties and crop productivity. The main objective of this study was assess the impact adoption on We coupled agent-based productivity models farmers’ management decisions maize under different rainfall scenarios in Ethiopia. A household survey conducted with 100 households from 5 villages ...

This study examines the impact of contract farming with Farmer Organizations on farmers’ income. Contract farming with farmer organizations is a smallholder farmer-inclusive contract farming system. Field surveys were conducted in August 2010 with 75 farmers (including 39 contract farmers) in Kampong Thom province, Cambodia. The analysis—i.e., using a treatment effects model—indicates that cont...

In the central dry zone of Myanmar, mean annual rainfall is less than 1000 mm. Although rainfed agriculture commonly practiced there, feasibility farming compromised by large fluctuations and frequent occurrence years. The monthly distribution follows a bimodal pattern. intensity monsoonal from May to October characterized two peaks, an early peak (May-June) late (August–October), separated int...

Abstract This study aims to determine the potential and limitations of land in Ngawi District, East Java, Indonesia, for cultivating rice, corn, soybeans. The research consists a four-stage field conducted Regency: (1) organization units; (2) determination observation points through stratified proportional sampling each unit; (3) surveys; (4) laboratory analysis. evaluation was accordance with ...
