Response of potato yield, soil chemical and microbial properties to different rotation sequences of green manure-potato cropping in North China

The long-term effect of organic and inorganic fertilizers on nutrient build-up and their relationship with microbial properties in a rice-wheat cropping sequence were studied in surface (0–15 cm) and subsurface (15–30 cm) soil samples. This experiment has been in progress since 1990 in the Department of Agronomy, CSK, Palampur with twelve treatments involving combinations of organic and inorganic fertilizers. In these treatment combinations, 25 and 50% of the recommended nitrogen levels were supplemented with organic sources, i.e. FYM (farm yard manure), green manure and wheat straw. The buildup of organic matter, and the total and available pools of nitrogen, phosphorus and sulphur were determined in surface (0–15 cm) and subsurface (15–30 cm) soil samples. The substitution of 25 and 50% nitrogen through organic fertilizers proved to be better than inorganic fertilizers alone. Amongst the organic sources, the substitution of FYM resulted in higher organic carbon, total and available nitrogen, phosphorus and sulphur than green manure or wheat straw. The substitution of 50% nitrogen through organic fertilizer was more effective than the substitution of 25% nitrogen. The relationships between the total and available pools of nutrients and the total microbial count, biomass carbon, microbial respiration, and the dehydrogenase and phosphatase enzymes were studied. The total pool of nutrients showed a high, positive, significant relationship with all these parameters.

The features of the formation of productivity of potatoes of the Red Scarlett variety were studied during cultivation against the background of applying different combinations of organic, mineral, sideral fertilizers and straw in the conditions of the forest-steppe of the Middle Volga. The studies were carried out in the field experiment in 2014–2016 on gray forest soil with medium loam particle size distribution, on the experimental field of the Department of Plant Growing and Horticulture at KSAU. The humus content in the soil of the experimental plot was 3.48-3.65 % (according to Tyurin), labile phosphorus amounted to 128-135, exchange potassium amounted to 152–165 mg/kg of soil (according to Kirsanov), pH of the salt extract was 5.5-5.6. The experiments were performed on eight grounds with mineral nutrition. The potato yield in the reference ground due to natural fertility was 18.26 t/ha. Separate application of mineral fertilizers in a dose of N60P60K90 over an average of three years increased the tuber yield as compared to the reference of 10.19 ha, while the introduction of 60 t/ha of manure increased the yield by 8.95 t/ha. Using a traditional fertilizer system (N60P60K90 + 60 t of manure), the yield was 34.95 t/ha. As a result of the transition to the biological fertilizer system (background + green manure + straw), the yield increased to 36.26 t/ha, which is 1.31 t/ha higher compared to the traditional fertilizer system. On average, over 3 years, the maximum tuber yield of 37.48 t/ha was obtained by applying mineral and organic fertilizers, as well as straw. Sidereal fertilizers and straw provided an increase in the yield of tubers of 7.81 t/ha. The best results for the dry matter content (22.05 %) and starch (16.04 %) were demonstrated by tubers from the reference variant. More protein (2.95 %) and vitamin C (21.24 mg %) contained in tubers from the variant when mineral fertilizers were applied in a dose (N60P60K90-background) + green manure + straw.

Common Potato

Field experiments were conducted to determine the effect of green manure as fallow on common scab of potato caused by Streptomyces turgidiscabies. Significantly fewer diseased tubers were harvested from soil incorporated with lopsided oat or woolly pod vetch compared with those from oat and continuous potato cultivation in a planter experiment. Each field experiment consisted of lopsided oat cultivated during the spring and summer prior to the potato planting. Comparisons were also made with several other treatments, including cultivation of woolly pod vetch, oat, soybean, sugar beet, and potato (‘Yukirasya’, which is resistant to potato common potato scab) and soil application of Ferosand (Fe, mainly FeSO4, to decrease the soil pH). In field experiments conducted during 1999–2000, treatment with lopsided oat followed by lopsided oat or woolly pod vetch was significantly more effective at suppressing the disease severity than oat and continuous potato cultivation (P < 0.001). An increase in the marketable tuber ratio was also more significant than for oat and continuous potato cultivation (P < 0.001). In field experiments conducted during 2000–01, lopsided oat cultivation alone and with the application of Ferosand (1.8 t/ha) or resistant potato cultivar treatment were significantly more effective at suppressing the disease severity and incidence than sugar beet cultivation (P < 0.001), even under high disease intensity in the field. However, potato yield had a tendency to reduce after lopsided oat treatment with an application of Ferosand (1.8 t/ha) compared with lopsided oat alone or the application of Ferosand at 600 kg/ha, due to low pH conditions. In field experiments conducted during 2001–02, the lowest severity and incidence of common scab of potato were observed in soil treated with lopsided oat than with other treatments (P < 0.05 and P < 0.001, respectively). These findings suggest that lopsided oat used as fallow green manure can reduce the severity of common scab and increase potato yield.
