Rainfed Farming

This research aims to identify factors correlated significantly to the motivation of farmers in perseving traditional rainfed farming systems, such as using local seeds and planting once a year.  The population of this study is farmer who still perform the traditional paddy farming system in the Village of North Tapanuli Parbaju Julu County North Sumatra Province. As much as 48 respondents randomly selected from 160 farmers.  A descriptive analyse and Spearman rank correlation are applied in this study.   The study showed that formal education, farmers' perception of the traditional system of rice farming are correlated significantly to farmer motivation in preserving tradional farming system while non-formal education, the traditional system of farming experience, farm size, number of family members are not.  Factors that correlated significantly to farmer motivation in maintaining local seed is non-formal education, farming experience, while the traditional system of formal education, farmers' perception of traditional rice farming system, farm size, number of family members are not correlated significantly.  Furthermore, the number of family members is merely factor that correlated significantly to the farmers motivation in maintaining once a year plantings while others factors are not correlated. Key words: farmer motivation, preserving, traditional farming

A computer simulation model* of the water balance for plants growing on coarse soils was developed and tested against field measurements. The inputs for this model are measurable physical parameters. From the close agreement between simulated and observed results, it is suggested that evaporation, soil water storage and deep drainage may be satisfactorily predicted.

Cereal-cowpea intercropping has become an integral part of the farming system in Mali. Still, information is lacking regarding integrated benefits of the whole system, including valuing of the biomass for facing the constraints of animal feedings. We used farmers’ learning networks to evaluate performance of intercropping systems of millet-cowpea and sorghum-cowpea in southern Mali. Our results showed that under intercropping, the grain yield obtained with the wilibali (short maturing duration) variety was significantly higher than the yield obtained with the sangaranka (long maturing duration) variety whether with millet (36%) or sorghum (48%), corresponding, respectively, to an economic gain of XOF (West African CFA franc) 125 282/ha and XOF 142 640/ha. While for biomass, the yield obtained with the sangaranka variety was significantly higher by 50% and 60% to that of wilibali with an economic gain of XOF 286 526/ha (with millet) and XOF 278 516/ha (with sorghum). Total gain obtained with the millet-cowpea system was significantly greater than that obtained with the sorghum-cowpea system by 14%, and this stands irrespective of the type of cowpea variety. Farmers prefer the grain for satisfying immediate food needs instead of economic gains. These results represent an indication for farmer’s decision-making regarding cowpea varieties selection especially for addressing household food security issues or feeding animals.

Two farming system research models were laid out on farm at KVK Gariyaband during 2014-15 and 2015-16 with an aim to study the economic viability and employment generation of the models. Model I was laid out in 3.5 acre area under rainfed conditions and Model II was laid out in 1.5 acre area under irrigated conditions. IFS Model II under irrigated conditions proved to be more remunerative with highest average net returns of Rs.452096 indicating better economic viability and better employment generation capacity as compared to IFS Model I under rainfed conditions.

Farmers' Participatory Varietal Evaluation (PVE) was conducted on sorghum (Sorghum bicolor) crops in the Kile-Bisidimo plains of eastern Ethiopia for three consecutive years, 1995–1997. The study aimed at providing farmers with alternatives to their landrace to enable them to overcome crop losses and to identify farmers' varietal selection criteria for inclusion in future breeding work. In 1995 constraints and opportunities in sorghum growing and farmers' varietal matching characteristics were identified through an informal survey. This was followed by a search for varieties and acquisitions of seed. Subsequently, eight varieties were evaluated of which five varieties were released and three were at the pre-release stage.In 1996 and 1997 farmer-managed on-farm trials were conducted and farmers evaluated the performance of the experimental varieties against a locally grown cultivar. Through pairwise and matrix ranking, farmers' selection criteria were listed, preferred varieties identified and initiatives taken to diffuse the varieties through the local seed system. Out of the eight varieties that research workers considered the best, farmers selected only three. The study negated the generally accepted view that farmers in lowland areas of eastern Ethiopia are reluctant to grow short-duration varieties. The selection and introduction of three new varieties into a farming system where farmers were growing only one local variety reconfirmed PVE to be a means for enhancing adoption and increasing genetic diversity. The study also confirmed that increasing farmers' access to their preferred varieties would result in a faster rate of diffusion through farmer-to-farmer seed exchange.
