SUMMARYAchieving export growth in rice production from variable rainfed lowland rice ecosystems is at risk if depending on conventional breeding or genetic development alone. Sustained, long-term production requires building adaption capacity of smallholder farmers to better manage the challenges of seasonal climate variability and future climate change. Better understanding of the risks and constraints that farmers face in managing their current cropping system helps develop strategies for improving rice production in Cambodia. System models are now considered valuable assessment tools for evaluating cropping systems performance worldwide but require validation at the local level. This paper presents an evaluation of the APSIM-Oryza model for 15 Cambodian rice varieties under recommended practice. Data from a field experiment in 2011, conducted in a non-limiting water and nutrient environment, are used to calibrate varietal-specific coefficients and model input parameters. An independent dataset is then used to validate the model performance for a ‘real-world’ situation using on-farm data for six rice varieties planted in 54 farmer fields on 32 farms in two villages of Southeastern Cambodia. From this analysis, the APSIM-Oryza model is shown to be an acceptable tool for exploring the mismatch between current on-farm yields and potential production through yield gap analysis and the exploration of cropping system options for smallholder farmers to increase production, adapt to seasonal climate variability and be prepared for potential climate changes.

On Farm

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.

Two field experiments were carried out during two consecutive rabi seasons of 2002-03 and 2003-2004 at Farming System Research Site, Chabbish Nagar, Rajshahi (AEZ 11) with a view to assessing the effect of Rhizobium inoculation on four varieties of chickpea viz., BARI Chola-3, BARI Chola-4, BARI Chola-5 and BART Chola-6. Each variety was tested with and without Rhizobium inoculation. Each plot received basal application of 22 kg P/ha as TSP, 42 kg K/ha as MOP, 20 kg S/ha as gypsum and 5 kg Zn/ha as zinc oxide. Peat based rhizohial inoculurn (Rhizohium strain RCa-220) @ 1.5 kg/ha was used for seed inoculation. Inoculated plants gave significantly higher nodule number, nodule weight, stover yield and seed yield compared to uninoculated plants. Among four varieties, BARI Chola-3 produced the highest nodule number, nodule weight and stover yield, while the highest yield was obtained from BARI Chola-4.

The Village

This research aims to determine the performance of new varieties of farm (VUB), lowland rice through an integrated approach to crop management (ICM) in the village of Gle Aneuk Indrapuri, Aceh Besar District. Field assessment is from cooperative farmers who have lowland rice varieties with treatment, such as Cimelati, Bondoyudo, Ciherang, Kalimas, VUTB Fatmawati and IR-64. In each of these rice varieties applied packages introduced PTT technology. The result indicates that reviewed the six varieties suitable for cultivated and developed. Judging from the performance of agronomic VUTB Fatmawati better compared with 5 other varieties. VUTB Fatmawati have the greatest production (7.75 tonnes / ha) with a profit-making Rp.6.074.750, -. Fatmawati lowland rice farming system with ICM pattern is more feasible to be developed because the RC has the largest ratio (2.09) compared with the varieties Cimelati (2,06), Kalimas (2,04), Bondoyudo (2,02), Ciherang (1,51) and varieties of IR-164 (1,39).Key words: farming, rice, varieties, integrated crop management

Agricultural Mechanization

Agricultural mechanization in developing countries has taken at least two contested innovation pathways—the “incumbent trajectory” that promotes industrial agriculture, and an “alternative pathway” that supports small-scale mechanization for sustainable development of hillside farming systems. Although both pathways can potentially reduce human and animal drudgery, the body of literature that assesses the sustainability impacts of these mechanization pathways in the local ecological, socio-economic, cultural, and historical contexts of hillside farms is either nonexistent or under-theorized. This paper addresses this missing literature by examining the case of Nepal’s first Agricultural Mechanization Promotion Policy 2014 (AMPP) using a conceptual framework of what will be defined as “responsible innovation”. The historical context of this assessment involves the incumbent trajectory of mechanization in the country since the late 1960s that neglected smallholder farms located in the hills and mountains and biased mechanization policy for flat areas only. Findings from this study suggest that the AMPP addressed issues for smallholder production, including gender inequality, exclusion of smallholder farmers, and biophysical challenges associated with hillside farming systems, but it remains unclear whether and how the policy promotes small-scale agricultural mechanization for sustainable development of agriculture in the hills and mountains of Nepal.
