An analysis of household farm investment decisions under varying land tenure arrangements in Ghana JARTS
Ayamga, Michael; Yeboah, Richard W. Nartey; Ayambila, Sylvester Nsobire.
Land tenure insecurity is widely perceived as a disincentive for long-term land improvement investment hence the objective of this paper is to evaluate how tenure (in)security associated with different land use arrangements in Ghana influenced households’ plot level investment decisions and choices. The paper uses data from the Farmer-Based Organisations (FBO) survey. The FBO survey collected information from 2,928 households across three ecological zones of Ghana using multistaged cluster sampling. Probit and Tobit models tested the effects of land tenancy and ownership arrangements on households’ investment behaviour while controlling other factors. It was found that marginal farm size was inversely related to tenure insecurity while tenure insecurity...

Economic gains of improving soil fertility and water holding capacity with clay application: the impact of soil remediation research in northeast Thailand AgEcon
Saleth, Rathinasamy Maria; Inocencio, Arlene; Noble, Andrew D.; Ruaysoongnern, Sawaeng.
Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44...

G. Villanueva-López, P. Martínez-Zurimendi, L. Ramírez-Avilés, F. Casanova-Lugo, and A. Jarquín-Sánchez. 2014. Influence of livestock systems with live fences of Gliricidia sepium on several soil properties in Tabasco, Mexico. Cien Inv. Agr. 41(2): 175-186. The aim of the current study was to evaluate the effects of two livestock systems, a livestock system with live fences (LSLF) of Gliricidia sepium associated with signal grass (Brachiaria decumbens) and a livestock system based on a grass monoculture (LSPM), on specific physical and chemical soil characteristics at different depths and distances from the fence. In each system, we randomly selected 9 plots of 600 m². A completely randomized design was used with a 2 x 3 factorial arrangement in which we...

การปลูกพืชสลับในไร่อ้อยเพื่อปรับปรุงดินและเพิ่มผลผลิตอ้อย ในภาคตะวันออกเฉียงเหนือ Thai Agricultural
Putchanee Arpornrat; Usa Jakrarat.
The experiment aimed to study the effects of crop rotation in sugarcane field during the last ratoon harvest and planting a new sugarcane crop, on soil improvement, increasing sugar yield and economic return in northeast Thailand. The effect of Jack bean (Canavalia ensiformis), sunn hemp (Crotalaria juncea), upland rice (Oryza saliva L.) fallowed as the rotation system. The experiment was a Randomize Complete Block Design with three replications and 7 treatments. They included T1) farmer’s method (fallow followed by sugarcane receiving chemical fertilizer control (15-15-15 at 50 kg/rai), T2) fallow followed by sugarcane receiving chemical fertilizer (16-16-16 at 25 kg/rai+22-8-10 at 25 kg/rai and compost fertilizer at 2 tons/rai), T3) sunn hemp planting as...
