The study was conducted in the nursery of Hort. Dept., College of Agriculture and Forestry, Mosul University, Iraq, during 2018 season to study the response of budded "Zaghinia" apricot on seedlings rootstock to bio, organic and chemical fertilizers, and their effects on seedling growth. The studied factors were as follows: Bio fertilizer Fulzyme (0,1and 2 g. seedling-1 ), organic fertilizer (Rice residue) (0, 1 and 2 kg. seedling-1 ) and DAP fertilizers (0, 5 and 10 g. seedling-1 ). The study was performed by using split-split plots within factorial experiment in randomized complete block design (RCBD), with 3 factors and 3 replicates, by using 6 seedlings for each treatment. Treatment means were compared by using Duncan multiple levels at 5% p. the most important results obtained were as follows: 1 and 2 gm.seedling-1 of bio fertilizer (Fulzyme) and Chemical fertilizer (DAP) at the levels 5 and 10 g. seedling-1 affected significantly resulted in a significant increase in soil available nitrogen, while the addition of organic fertilizer (rice residues) and for both levels 1 and 2 kg. Seedling-1 gave a significant increase in nitrogen, phosphorus, ready-made potassium and pH of the seedling soil, and the bilateral interaction had a significant role in the growth of seedlings, especially the treatment of the interaction between the fertilizer (Fulzym) and organic fertilizer (Rice residues), which have a significant effect in giving the best results in available nitrogen, phosphorus and potassium in the soil, and the triple interference also gave a significant increase in all studied traits.

Optimization of the nitrogen (N) inputs and minimization of nutrient losses strongly affect yields in crop rotations. The aim of this research was to evaluate the effect of agricultural practices on yield and N use in a 4-year cereal-legume rotation in organic farming and to identify the best combination of these practices. The following treatments were compared: conventional plough (P) vs. reduced chisel (RC) tillage; composted farmyard manure (F) vs. unfertilized control (NF); and green manure (GM) vs. no green manure (NoM). No significant differences were found for N use efficiency between P and RC in each crop. The results suggested that legumes in the tested rotation do not need supplemental N fertilization, particularly if combining GM and F. The use of composted farmyard manure should be considered in a long-term fertilization plan for cereals, to allow a higher efficiency in N use. The residual effect of fertilization over time, along with the site-specific pedo-climatic conditions, should also be considered. In both tested tillage approaches, soil N surplus was the highest in plots combining GM and F (i.e., more than 680 kg N ha−1 in combination with RC vs. about 140 kg N ha−1 for RC without fertilization), with a risk of N losses by leaching. The N deficit in NoM–NF both combined with P and RC would indicate that these treatment combinations are not sustainable for the utilized crops in the field experiment. Therefore, the combination of the tested practices should be carefully assessed to sustain soil fertility and crop production.

SummaryThe effect of three herbicides and an insecticide combination on nitrogen fixation in three paddy soils was investigated in a laboratory incubation study. The influence of pesticide combination on N2 fixation was evaluated in the presence and absence of rice straw under flooded and non-flooded conditions. In a non-flooded alluvial soil single or combined application of butachlor and carbofuran significantly stimulated N2 fixation. There was no effect on N2 fixation when thiobencarb was applied alone; but with thiobencarb in combination with carbofuran higher N2 fixation occurred. Both oxadiazone and thiobencarb had no effect on N2 fixation under flooded conditions, but in combination with carbofuran the N2 fixation was high. In acid sulphate saline Pokkali soil, rice straw application stimulated N2 fixation; the stimulatory effect of carbofuran either alone or in combination became more pronounced under flooded conditions. N2 fixation was low in a laterite Sukinda soil and the effect of pesticides was not changed by rice straw amendment. A uniform stimulation of N2 fixation occurred in soils when carbofuran was applied either singly or in combination with other herbicides tested. Results indicate that the effect of pesticides on N2 fixation varied with the rice straw application and water regime.

Abstract The sustainability of rice-wheat system (RWS) in north-western India is threatened due to the deterioration of soil health and emergence of new challenges of climate change caused by low nutrient use efficiency and large scale burning of crop residues. Phosphorus and phosphatase activities in the soil aggregates affected by different residue management practices remain poorly understood. Thus, soil samples were obtained after a five year field experiment to identify the effect of tillage, green manure and residue management on aggregate-associated phosphorus fractions. In rice, the main plot treatments were combinations of wheat straw and Sesbania green manure (GM) management: (1) puddled transplanted rice (PTR) with no wheat straw (PTRW0), (2) PTR with 25% wheat stubbles (12-15 cm long) retained (PTRW25), (3) PTR without wheat straw and GM (PTRW0+GM), and (4) PTR with wheat stubbles (25%) and GM (PTRW25+GM). Three sub-plots treatments in the successive wheat crop were (1) conventional tillage with rice straw removed (CTWR0), (2) zero tillage (ZT) with rice straw removed (ZTWR0) and (3) ZT with 100% rice straw retained as surface mulch (ZTWR100). Results of the present study revealed that all phosphorus fractions were significantly higher in PTRW25+GM followed by ZTWR100 compared with PTRW0/CTWR0 treatment within both macro- and micro-aggregates. The total phosphorus (P), available P, alkaline phosphatase and phytin-P were significantly higher under ZTWR100 than CTWR0. Principal component analysis identified NaOH-Po, NaHCO3-Pi and HCl-P as the dominant and reliable indicators for evaluating P transformation within aggregates under conservation agriculture based practices.

Legume Green Manure

Legume green manure is extensively planted to improve soil fertility in crop field. However, the application of legume in Eucalyptus plantation is still limited and depends on site specific and species. Therefore, the objective of this study was to determine the effects of green manure inter-plantation on soil fertility and plant growth of Eucalyptus plantation in a short term. A field experiment of one year was established to investigate the green manure growth, forest soil nutrients and Eucalyptus plant growth inter-planted with two legume species (Tephrosia candida, TC and Sesbania cannabina, SC) at south subtropical China. Legumes were inter-planted in linear among the tree space of Eucalyptus stand. Result showed that the green manure inter-plantation increased soil organic matter by 9.66% of TC and 18.44% of SC. Soil available nitrogen, phosphorus and potassium were improved significantly by the legume treatments as well. The increment of height and diameter in breast height of Eucalyptus during the experiment was significant in legume treatments. Thus, the timber volume increment was improved significantly by 46.81% of TC and 35.47% of SC compared with the control treatment. Therefore, the inter-plantation of legume green manure under the Eucalyptus plantation is effective to improve soil fertility and tree growth. Such a measure is potential and referenced for the sustainable forest management.
