The effect of ridge and furrow film mulching (RFFM) on soil microbial communities, physicochemical property, enzymatic activity, and tuber yield were studied under the potato (Solanum tuberosum L.) continuous cropping fields managed for one (CY-1), two (CY-2) and four years (CY-4). Experimental treatments included a conventional flat plot without film mulching (FP) and five RFFM treatments: (i) a flat plot with film mulching (T1); (ii) on-ridge planting with full film mulching (T2); (iii) on-furrow planting with full film mulching (T3); (iv) on-ridge planting with half film mulching (T4); and (v) on-furrow planting with half film mulching...

The frequent occurrence of years with extreme drought leads to the investigation of measures for mitigation of their impacts. The efficiency of organic mulch materials - straw and compost application as the preservation of potato production in drought conditions were verified in this study. Three mulching treatments were verified during the three experimental years (2016-2018) in an exact field trial with potatoes cv. Dicolora. Wheat straw mulch in the rate of 2.5 t/ha (SM1) and 4.5 t/ha (SM2), compost in the rate of 20 t/ha (CM), and control block without any treatments (C) were used. The yield of marketable tubers (tuber over 40 mm) showed a significant...

This research aimed to compare the productivity of three species of pulse plants (Vicia faba L., Pisum sativum L., Lupinus angustifolium L.) in acidic sandy loam soil and to determine the influence of NPK (N0P0K0, N0P27K73, N30P27K73) fertilisers on grain yield and nitrogen assimilation. The experiments were conducted Voke Branch of Lithuanian Research Centre for Agriculture and Forestry (Baltic Sea region, 54°33'49.8''N, 25°05'12.9''E) in 2016-2018. Fertilisation with PK increased the grain yield of Vicia faba L. and Pisum sativum L. (P < 0.05) and had no effect on the yield of Lupinus angustifolium...

The water demand for cover crops (CC) should be considered to achieve competitive crop stands for weed control also under unfavorable conditions. This study aims to estimate the weed suppressive ability of winter CC, as Sinapis alba L., Phacelia tanacetifolia Benth., Vicia sativa L. and Avena strigosa Schreb., under a water-limited regime. The water deficit tolerance of different CC was determined in a greenhouse experiment by measuring the maximum quantum efficiency of photosystem II. Moreover, soil moisture, CC, and weed establishment were measured in field experiments in Southwest-Germany during two contrasting...

Hybrid rice has a higher yield potential than inbred rice, but the difference in CH4 emissions between the two groups is still unclear, particularly regarding straw incorporation. In the present study, a pot experiment was conducted to examine the difference in CH4 emissions between inbred (Huanghuazhan) (IR) and hybrid (Rongyouhuazhan) (HR) rice cultivars, both with or without straw incorporation in subtropical China. The results showed that HR produced both greater grain yield and biomass than IR. In contrast, when compared with IR, HR reduced the...

Aiming at the problems of shallow effective soil layering and low utilization rate of precipitation in the North China Plain. The effects of different subsoiling stages on soil physical properties and water use in winter wheat/summer maize fields were studied. Three kinds of tillage treatments were studied: rotary tillage to a depth of 15 cm in October and no-tillage in June (RT), rotary tillage to a depth of 15 cm in October and subsoiling to 35 cm in June (ST-J), subsoiling to a depth of 35 cm in October and no-tillage in June (ST-O). Changes in soil bulk density and soil compaction were consistent over two seasons. Compared to RT, in the 10-50 cm...

To assess the response of promising safflower genotypes to late-season drought stress in delayed planting conditions, an experiment was conducted in two years (2016-2017 and 2017-2018) in Iran. The irrigation regime was specified in two levels, including normal irrigation and irrigation cut off in the seed filling stage in main plots, and five safflower genotypes, including Soffe, Goldasht, Golmehr, Padideh, and Parnian were categorized in subplots. Applied drought stress significantly reduced the seed yield and yield components of all genotypes, which accompanied with a substantial decrease in oil content and oil yield of all genotypes. However, the...
