Opis:
This study was carried out in Harrabot village of Tarkughat VDC, Paundi and Majuwa village of Sundarbazar Municipality of Lamjung district during 2015/2016. Thirty households (10 HH from each village) who were involved in seed production were purposively selected for survey. The respondents’ knowledge was gathered through focus group discussions and household surveys, using a pretested semi-structured questionnaire. Seed routine test was carried out in the Agronomy lab of Lamjung Campus. Results revealed that the dominant features of farming in the study areas were small land holdings, fragmented and sloping land with rainfall-dependent farming. Land distribution pattern was 12.93% marginal land, 16.35% upland and 70.72% irrigated lowland. Farmers grew rice, maize, mustard and pulses as major crops and fruits, vegetables, potato and flowers as minor crops. Major cropping pattern were Rice-Mustard-Maize, Maize-Rice-Fallow, Rice-Fallow-Rice etc. Nutrient-poor soils, low pH, farmers' poor access to inorganic fertilizers, soil-depleting cropping patterns, lack of technical knowledge on crop management, soil erosion and degradation are major challenges. Insects, diseases and weeds were major biotic constraints, while lack of irrigation, drought and lack of technical support were major abiotic constraints of rice production. Sukhadhan-2, Sukhadhan-3, Sukhadhan-4, Sukhadhan-5 and Sukhadhan-6 were planted in rain-fed lowland, whereas Ramdhan, Sunaulo sugandha, Loktantra, Sabitri and Makwanpur-1 were grown in irrigated lowland. Seed producers used 39.07% of the land for seed production with 4.78 tons ha-1 of seed productivity. Most of their produced seed was send to Sundar Seed Coop Ltd., Paudibazar, while some seed were stored in their home by using local containers such as earthen pots, plastic drums, metal bins, Dali, Kotho, Bhakari etc. The tested seed quality parameter in the lab showed that the average moisture, purity and germination percentage of the seed samples were 13.87%, 94.13% and 96.72%, respectively.

Opis:
The irrigation area of Parsanga is located in Sumenep Regency, Madura Island of Indonesia. This irrigation area is 500 ha and the existing cropping pattern is paddy–paddy–second crop. There is water discharge deficiency due to the existing cropping pattern mainly in the dry season. Thus, this study intends to optimize the cropping pattern for 3 condition so that it can produce the maximum benefit of agricultural product. The first cropping pattern is paddy/second crop–second crop–paddy/second crop; the second proposition is paddy/second crop –paddy/second crop–second crop; and the third proposition is paddy–second crop–paddy/second crop. The optimization analysis is carried out by using the linear programming. The suggested three cropping patterns are not only able to solve the water deficiency; they can also present the more production benefit than the existing condition.
Nawadniany obszar Parsanga znajduje się w dystrykcie Sumenep na wyspie Madura w Indonezji. Ma powierzchnię 500 ha, a system upraw tam stosowanych to ryż–ryż–drugi plon. W warunkach takiego systemu uprawy występują deficyty wody, szczególnie w porze suchej. Z tego powodu przedstawione badania miały na celu optymalizację systemu upraw w trzech systemach, aby uzyskać maksymalne korzyści w produkcji rolniczej. Trzy systemy to: 1 – ryż/drugi plon–drugi plon–ryż/drugi plon, 2 – ryż/drugi plon–ryż/drugi plon–drugi plon i 3 – ryż–drugi plon–ryż/drugi plon. Optymalizację wykonano z zastosowaniem programowania linearnego. Sugerowane trzy systemy są w stanie nie tylko rozwiązać problem deficytu wody, ale także dają korzyści produkcyjne większe niż obecnie uzyskiwane.

Opis:
The climatic, soil, ecological and economic features of the natural landscapes in the Krasnodar Krai were analyzed. The land structure of cultivated land in Western Ciscaucasia was given; the current state of soils in the Krasnodar Krai was analyzed. The changes in the content of humus in the arable layer over the century were considered. The qualitative state of agricultural lands, such as the susceptibility to erosion, the content of humus, and indicators of the nutrients balance in the soil was shown. A conclusion the existing zonal agriculture systems do not use the landscape diversity of the region was drawn. The need for switching to the adaptive landscape system of agriculture was substantiated. Using the GIS technologies, the boundaries of the natural landscapes in the Krasnodar Krai and the areas of agricultural land was determined by types and the degree of the manifestation of erosion processes. An eco-economic assessment of the field crop rotations adapted to the natural landscape by cultivated lands was made.
