Abstract Three woody species Forsythia x intermedia ‘Lynwood’, Weigela ‘Bristol Ruby’, and Prunus laurocerasus ‘Otto Luyken’ were grown in 5 liter (# 1.3) containers with white peat and peat-reduced substrates. Plants were fertilized by a controlled-release or organic fertilizer. The aim was to investigate the relation between mineral N-content in the substrate and growth and N-uptake of the plants. Plant biomass was influenced by the mineral N-content in the substrate and by the substrate, but not by the type of fertilizer. Plant biomass of plants in the white peat substrate was significantly greater than plants grown in the peat-reduced substrates. Different equations describe the relation between mineral N in the substrate and biomass. Only for the white peat substrate in June and August was the slope of these regressions significant and the determination coefficient (r2) high. Dry matter of above ground biomass was 38% of fresh matter. The root-to-shoot ratio varied widely. There was a significant exponential relation between the biomass and the height of the plants, but not with the number of shoots. The N-content of the plant was related to its fresh matter. The findings establish a possibility to deduce N-uptake from plant biomass and thus improve fertilization.

A field experiment was carried out during kharif season of 2010 and 2011 at Sriniketan Research Farm, Visva-Bharati, West Bengal, India. The yield attributes and growth parameters were significantly higher in case of sole maize and intercropping treatments with legumes. The maximum total chlorophyll (chlorophyll a + chlorophyll b) was observed on sole maize, which was statistically at par with maize crop under intercropping system. In the middle canopy, highest light interception (%) was observed in maize + groundnut (2:4). The grain yield (2.48 t ha-1) and stover yield (5.07 t ha-1) of maize were significantly higher in sole maize than either of its intercropping systems with legumes. The legume yield was highest in maize + groundnut (1:2) followed by sole groundnut. The maize equivalent yield (7.06 t ha-1) was highest in maize + groundnut (2:4) followed by maize + groundnut (1:2). The highest benefit cost ratio maize + groundnut (1:2) closely followed by maize + soybean (1:2). The total N uptake by sole maize was significantly higher and under intercropping systems, the highest N concentrations in grain and straw, and protein content in grains were obtained in maize + soybean (1:2) and maize + groundnut (2:4) treatment.

Okra fruit contains phenolic compounds as natural antioxidant. The aim of this research was to analyze the effect of different types of fertilizers on production and quality of two okra varieties. The experiment was conducted in October 2017 to February 2018 at Bogor Agricultural University experimental field at Leuwikopo, Darmaga, Bogor (-6033’49.3”SL, 106043’30.7’’EL). The experiment used nested randomized complete block design with 2 factors and 4 replications. The first factor consisted of two okra varieties with different colour (red and green okra). The second factor was fertilizer types consisted of no fertilizer, organic (cow manure), combination of organic + inorganic, and inorganic fertilizer. The results showed that fertilizer types significantly affected plant height and fruit N content but did not affect fruit production. Red okra had a higher plant height, lower number of leaves and leaf K content than those of the green okra. The interaction effect of both factors was significant on total phenolic content in fruit and P content in leaf. The highest total phenolic content in fruit was showed by red okra with inorganic fertilizer, although it was not significantly different to those of red okra with combination organic + inorganic fertilizer, and also to green okra with organic fertilizer. The highest P content in leaf was found in red okra without fertilizer, however it was not significantly different to red okra with combination organic + inorganic fertilizer, green okra with organic fertilizer, and green okra with inorganic fertilizer.Keywords: inorganic fertilizer, leaf nutrient, organic fertilizer, phenolic compound

The mustard production and productivity of the hot arid region of Rajasthan is dominated by both genetic makeup and environmental conditions. An experiment was conducted with four mustard varieties  (RGN-73, RGN-229, RH-30 and Pusa bold) in two growing environments (open environment and neem shade). Pusa bold gave significantly higher plant height than other varieties. Among varieties, RGN-73 had significantly higher number of branches per plant, dry matter accumulation per plant, siliquae per plant, seed yield, stover yield, biological yield, harvest index and heat use efficiency than other varieties. However, significantly higher test weight was in Pusa bold variety. Under open environment condition, significantly higher growth, yield attributes, yield, harvest index and heat use efficiency were found as compared to neem shade environment. The results revealed that variety RGN-229 took more days for completion of life cycle as compared to other varieties, hence RGN-229 variety required significantly more degree days than other varieties. The pheno-thermal index was significantly higher in open condition.

Digestate is an anaerobic digestion by-product rich in inorganic-nitrogen (N) that can be used as an organic fertilizer. Digestate agronomic efficiency and its impact on the environment have not yet been studied in detail, therefore this study tries to fill this gap. The agro-environmental sustainability of digestate fractions was evaluated in a holistic way by comparing the best management practices available in the Veneto Region agroecosystem. A farm experiment involving mineral fertilizer and both liquid and solid digestate fractions was established involving silage winter wheat and silage maize as main crops. Agro-environmental sustainability was investigated coupling crop performance analysis (e.g., yield, N uptake and N use efficiency (NUE)) with a novel proposed agro-environmental sustainability index (AESI) (i.e., product of the dry yield and NUE). The results showed that the liquid digestate fraction gave agronomic performances comparable to mineral fertilizers and a satisfying AESI while solid digestate showed lower performances. In conclusion, liquid digestate fractions might be an effective substitute for mineral fertilizers in the Veneto region agroecosystem reaching encouraging levels of agro-environmental sustainability. On the contrary, longer-term experiments are requested to evaluate solid digestate fraction sustainability.

Effects of thermally gasified pig manure ash (GA) and lime-free gasified ash (LF-GA) on properties of an acidic soil (pH 4.5) and the growth and elemental uptake of ryegrass (Lolium rigidum Gaudin) were investigated. The GA was an effective liming agent (2% addition raised soil pH from 4.5 to 7.9); both GA and LF-GA increased soil electrical conductivity and bicarbonate-extractable phosphorus (P). Soil fertilised with LF-GA supported slightly higher plant dry matter (DM) yield than GA (1.5–1.7 v. 1.2–1.5 g DM/kg soil) for the first harvest, due to greater initial P availability at pH <5 than at pH >6. However, plant yields for the subsequent two harvests were similar, as soil acidity dissolved lime in untreated ash (GA) over time. Maximum yields for ash-treated soil and soil treated with mono-calcium phosphate (MCP) were similar. Relative agronomic effectiveness of P sources for three harvests, based on plant P content compared with values for MCP, were 6, 11, and 12% for GA and 19, 10, and 33% for LF-GA. Internal efficiency of P utilisation was similar for all three P sources for each harvest, indicating that differences in yield were mostly a consequence of differences in P supply. Heavy metal concentrations in plants fertilised with ash were minor and within regulatory limits. In general, application of ash did not systematically affect the concentrations of elements (Al, B, Cd, Mg, Mn, Fe, Pb, S, Se) in plants.
