The Impact

The field experiment was conducted at the Agronomy farm of Sher-e-Bangla Agricultural University to evaluate the impact of different kind of green manures on soil nutrient balance through adding biomass and N,P and K accumulation. Green manuring crops were incorporated after in situ cultivation and results showed that, the biomass incorporation increased the N production in soil. The biomass from Sesbania rostrata, Sesbania aculeata and Crotalaria juncea gave the higher dry matter and nutrient status. Incorporation of Sesbania rostrata and Sesbania aculeata added more organic matter and nitrogen to the soil after green manure incorporation than the prior soil. However, the improved soil quality was recorded with S. rostrata and S. aculeata followed by C. juncea and V. unguiculata incorporation as compared to control (no green manure) and other green manuring crops. The nutrient balance of soil after incorporation of different green manuring crops specially S. rostrata, S. aculeata and C. juncea showed positive balance of nutrients than other green manures.

Important Character

An experiment was conducted at Sher-e-bangla Agricultural University during May to July, 2016 to examine the morpho-physical potentiality of eight green manure species and these species are viz. Sesbania aculeata, Sesbania rostrata, Crotalaria juncea, Vigna unguiculata, Vigna mungo, Vigna radiata, Leucaena leucocephala and Mimosa pudica. Leaves number, biomass production and nodulation are an important character of any green manuring crops as these crops are very potential for increasing soil fertility after incorporation. The growth habits of these species were studied from 15 DAS to 45DAS whereas dry matter/plant and nodulation data were taken from 25 DAS to 50DAS. At 45DAS, Sesbania aculeata, Sesbania rostrata and Vigna unguiculata shown 53% to 149% higher plant height compared to Vigna mungo, although C. juncea performed better at 30DAS compared to V. unguiculata. Again, C. juncea along with S. rostrata and S. aculeata gave the highest fresh biomass (24% to 72%), dry biomass (2.6t/ha to 5.25t/ha), dry matter plant-1 (60% to 83%) and nodulation compared to rest green manures at 45DAS whereas V. unguiculata produced higher dry matter plant-1 at 20DAS but later it declined insignificantly at 50DAS.The lowest performance was observed from V. mungo followed by V. radiata and M. pudica. It was shown that S. rostrata, S. aculeata, C. juncea, V. unguiculata and L.leucocephala performed better regarding biomass, dry matter and nodule production. Res. Agric., Livest.

During a three-year period from 1993 to 1995, experiments were conducted to determine the effect of the maize-legume associations on soil fertility and their impact upon the yields of subsequent bean crops. We studied under Research Station conditions on an Oxisol soil and on drainage plots in Ultisol soil, the following associations: for the agro-ecosystem South of Havana oxisol we considered maize + caupi; maize + velvet bean; maize + canavalia; maize + crotalaria; maize + sesbania. While for the agro-ecosystem of San Juan and Martinez (Utisol) treatments were : maize, maize + caupi; maize + velvet bean; maize + canavalia; millet and fallow soil. The results showed that the intercropping of maize with legume was beneficial on the evaluated soil properties, and that, if combined with minimum tillage in the Oxisols , they complement the beneficial effects of both agronomic practices of that type of soil. The impact of these legume-maize-treatments in the subsequent cultivation of beans was significant on seed yield compared to the obtained after maize alone. The nutrient balance was favored by the recycling of nutrients from green manure left by the legume-maize treatments used. The recycling if nutrients made possible a nitrogen reduction of 25%, and one of 100% for P2O5 and K2O. In the Ultisol soils drainage plots where established, in addition to the mentionated effects, we observed an anti-erosive impact of the treatments which diminished soil losses as compared to maize alone and fallow soil.

Green manuring is considered an important agronomic practice for smallholder farming systems in the tropics. Different species of legumes and non-legumes are applied either as ex situ or in situ green manures. Thus a field study conducted under rainfed conditions in Sri Lanka compared the effect of in situ and ex situ green manuring using two popular green manures ( Crotolaria juncea — a legume and Tithonia diversifolia — a non-legume) on the growth, seed yield and N use pattern of maize ( Zea mays ), the most popular upland cereal in the Asian tropics, grown with high and low N rates, in the two seasons that correspond to the monsoonal rains. In situ green manuring, especially with crotolaria, increased the growth, seed yield and N use efficiency of maize when compared to the ex situ addition of similar quantities of the green manure. The impact was also greater in the minor season, when the crop was subjected to moisture stress conditions. The benefits of in situ green manuring with tithonia were lower than those due to crotolaria. In situ green manuring with tithonia also led to a greater increase in growth, seed yield and N use efficiency in maize compared to ex situ green manuring with this species. The green manures, especially in situ application, also increased the benefits of enhanced rates of N fertilizer to the crops in both seasons, with greater use efficiency in the major season. The study showed the benefits of green manuring (both in and ex situ ) for obtaining higher yields of maize in the growing seasons of the Asian tropics, especially the in situ application of legume species.

The potential for suppling a portion of the required nitrogen (N) for aerial-sown rice crops by green manuring legume pasture was investigated in southern New South Wales. Green pasture material could be the source of up to 300 kg N/ha in the southern New South Wales ricegrowing systems. Three experiments were conducted over 2 seasons. Each included 3 land preparation treatments (fallow, pasture removed, pasture incorporated) split for 5 rates of N (0, 40, 80, 120, 160 kg N/ha) applied as urea immediately before flooding for aerial sowing. In all experiments fallow resulted in lower anaerobic incubation soil ammonium levels at flooding than the pasture-incorporated treatment. When the fallow was extended, N losses led to a decrease in grain yield. The incorporation of green manure resulted in an increase in grain yield at the nil N rate in experiment 1, where soil N levels were comparatively low and seasonal temperatures average. In experiment 2, where soil N levels were high and the temperatures before panicle initiation below average, the incorporation of green manure reduced total dry matter and increased per cent unfilled grain. Land preparation treatments did not affect total dry matter or grain yield in experiment 3, where a short season variety was grown and all treatments lodged severely. Grain yields in all experiments were affected by a season x soil fertility x variety interaction.

Green manures can enrich soils with organic matter and nitrogen. An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh, Bangladesh to evaluate the residual effects of different green manures on the growth and yield of wheat (BARI Gom-26). The experiment containing nine treatments were laid out in a randomized complete block design with three replications. The treatments were T1 [No green manure + 100% Recommended dose of nitrogen (RDN)], T2 (Sesbania aculeata + 75% RDN), T3 (Sesbania aculeata + 50% RDN), T4 (Sesbania rostrata + 75% RDN), T5 (Sesbania rostrata + 50% RDN), T6 (Vigna radiata + 75% RDN), T7 (Vigna radiata + 50% RDN), T8 (Vigna mungo + 75% RDN), and T9 (Vigna mungo + 50% RDN). Residual effects of green manures with RDN significantly increased the yield attributes as well as grain and straw yields of wheat. Further, green manures exerted significant residual effects on grain, straw and total N uptake of wheat. Among various treatments with green manures, the performance of T4 (Sesbania rostrata + 75% RDN) was the best as it produced the highest grain yield (4.28 t ha-1), straw yield (4.74 t ha-1) and total N uptake (108.02 kg ha-1). The use of green manures slightly increased the organic matter content, total N and available P, K, and S contents of the post-harvest soils. As regards to the contribution of various green manures on yield contributing characters and yield of wheat, performances of two Sesbania species viz., S. aculeata and S. rostrata in association with 75% N fertilizer were effective.Asian J.

The Impact

A 3-yr field study was conducted on a Dark Brown Chernozemic soil to assess the impact of the date of sweetclover (Melilotus officinalis Lam.) incorporation and tillage implement used for incorporation on succeeding spring wheat (Triticum aestivum L.) yields. During year 1 wheat was underseeded to sweetclover. In year 2 the clover was incorporated on either 15 June, 1 July or 15 July. Five tillage implements were evaluated (a) mouldboard plough (b) rotavator (c) tandem disc (d) offset disc and (e) deep tillage cultivator. In the spring of year 3, each treatment was seeded to wheat. Over the duration of the study only small and usually insignificant differences (P ≥ 0.05) in year 3 wheat yields occurred related to incorporation implement. Date of sweetclover incorporation during year 2 was a significant factor when the 15 June incorporation resulted in 6 and 17% greater wheat yields than 1 July or 15 July, respectively. Sweetclover dry matter production, measured at the early date of incorporation was 32% less than the two later incorporation dates. Mineral nitrogen, determined to a depth of 60 cm in year 3 immediately following wheat seeding, was 82, 75 and 62 kg ha−1 for the 15 June, 1 July and 15 July incorporation dates, respectively. It was concluded that the implement selected for sweetclover incorporation is not critical, however the timing of plough down is important and should be relatively early in the growing season in order to maximize succeeding grain production.Key words: Sweetclover, incorporation, green manure

The Impact

The impact of five rates of phosphogypsum (PG) (0, 5, 10, 20 and 40 t/ha) on the growth, nodulation and N 2 fixation of dhaincha ( Sesbania aculeata Pers.) was evaluated in a pot experiment, using sorghum ( Sorghum bicolor L.) as a reference crop. N 2 fixation by the legume crop was measured using the 15 N isotope dilution method. The dry matter content of sorghum doubled when the soil was supplied with the lowest rate of PG (5 t/ha). For sesbania, the highest rate of PG (40 t/ha) was found to have a significant effect on the dry matter yield. PG had a beneficial effect on phosphorus (P) accumulation in both plant species, particularly in the nodules of sesbania. The beneficial effect of PG on nodulation and N 2 fixation was more pronounced than on the host plant growth. The highest value of N 2 fixation (67%) was obtained following the addition of 10 t PG/ha, whereas it was only 35% in the control treatment (PG0). The amount of fixed N 2 doubled when the soil was supplied with PG, particularly in the PG10 treatment. The concentration of fluoride (F − ) in the shoots of both plant species was less than 10 mg/kg. In conclusion, PG improved nodulation, N 2 fixation and P availability in the legume species S. aculeata with minimal soil N uptake.

Due to their nitrogen fixation potential, legumes represent an alternative for supplying nutrients, substituting or complementing mineral fertilization in cropping systems involving green manuring. The objective of this study was to evaluate the N balance in a soil-plant system involving green manures [sunn hemp (Crotalaria juncea L.) and velvet bean (Mucuna aterrima Piper & Tracy)], both labeled with 15N. They were incorporated into two soils of contrasting textural classes: a clayey Eutrudox and a sandy-clayey Paleudalf, both cultivated with corn. The research was carried out in a greenhouse, using pots containing 6 kg of air dried soil, to which the equivalent to 13 Mg ha-1 dry matter of above-ground mass plus 2.7 or 2.2 Mg ha-1 of velvet bean and sunn hemp roots were incorporated, respectively, with 15N labeling of either shoots or roots. One hundred days after emergence of the corn, the velvet bean residues provided higher accumulation of N in the soil, higher absorption by corn plants and accumulation in the shoot. The green manure decomposition was more intense in the medium-textured Paleudalf. The highest nitrogen losses were also observed in this soil.

The effects of green manuring with dhaincha (Sesbania aculeata) and sunhemp (Crotalaria juncea) in combination with four levels of urea-N (0, 75, 150 and 225 kg N/ha) on the productivity of a subsequent sugarcane (Saccharum officinarum) crop and the fertility of the soil were examined. C. juncea contributed more nitrogen to the soils when ploughed down than S. aculeata (56·7 v. 40·0 kg N/ha). The green manures and the supplemented urea-N increased cane yield by 2 to 26% and 26 to 57%, respectively. The organic matter, total N, available P and S of the soil was only slightly increased by the incorporation of green manures.

ABSTRACT Maize intercropped with perennial green manure is an option to promote soil coverage, control weeds and recycle soil nutrients, in an organic system. This study aimed at evaluating the agronomic characteristics and yield of grains and organic maize straw intercropped with perennial green manures sown at different maize growth stages. A 3 x 2 + 1 factorial design was used, with three perennial species of green manure - calopogonium (Calopogonium mucunoides Desv.), tropical kudzu [Pueraria phaseoloides (Roxb.) Benth] and perennial soy [Neonotonia wightii (Wight & Arn) Lackey] - and two green manure sowing times - at the maize V4 (four expanded leaves) and VT (bolting) stages - plus a control treatment (maize monoculture). A randomized blocks design, with four replications, was used. Soil coverage, production of green manures dry matter and weeds, and maize growth and production variables were evaluated. The sowing of green manures at the V4 stage had a higher percentage of soil coverage, in relation to the VT stage. Calopogonium, when compared to the other green manure species, had the highest percentage of soil coverage (35.63 %) and dry matter (1.0 Mg ha-1). Perennial green manures grown intercropped with maize did not affect growth, grain yield and maize straw. However, they were not effective in suppressing weeds.
