The study examined the effect of weed control practices and different fertilizer sources for the optimum growth and yield of bell pepper. The study was conducted at the teaching farm of the Department of Crop Science, University of Nigeria, Nsukka. The sample for the study were weed control practices comprising black polyethylene mulch, un-weeded plot, and manual weeding with hoe at 2-week intervals and different fertilizer types comprising cow dung, pig dung, and poultry manure at 20 t/ha, respectively; NPK fertilizer at 150 kg/ha; and no fertilizer (control).

Abstract

Context: The introduction of quality-certified seed (QCS) in the informal farmer network-based seed systems, which have largely relied on informal signals of quality, represents a promising innovation towards integrated seed sector development, combining formal and informal sector elements. At the same time, behavioral nudges have emerged as potentially powerful ways to encourage the uptake of innovations among smallholder farmers in developing countries.

Abstract

In this study, we aim to estimate the causal effects of LLL on input usage and yield and use the results on treatment effect as inputs for the incremental cost benefit analysis in paddy production in the Mekong Delta region, Vietnam. The findings affirm the economic feasibility of the LLL technique, as indicated by both private and social analyses.

Laser land leveling technique for paddy mono-cropping system in Vietnam: Addressing land fragmentation, demand heterogeneity, and productivity

Submitted by Meseret Birhan… on
EfD Authors:
Loan, Le Thanh

PurposeThe study investigates determinants of willingness to pay (WTP) for laser land leveling (LLL) technology, its demand heterogeneity across individual farmers and plot characteristics and the technology's empirical impact on paddy productivity.Design/methodology/approachThe study applies the Becker-DeGroote, Marschak style to elicit the WTP for LLL technology and the Cragg model to examine the determinants of the WTP to capture both the demand decision and affordability.
