Strip Tillage

Three-year field trials were conducted to compare the effect of three tillage systems: strip-tillage (ST), strip-tillage after mouldboard ploughing (STmp) and conventional tillage (CT) on growth and yield of winter oilseed rape at the experimental station in Červený Újezd, Czech Republic. Compared to CT, the growth of roots and aboveground biomass was slower (significantly thinner root necks, shorter roots and leaves) under ST at the beginning of vegetation (BBCH 14–18). Plants under ST still had significantly thinner root necks, and a lower number of leaves than plants from CT before winter (BBCH 21) but the differences were no longer statistically significant in spring (BBCH 30). Despite a slower start, the ST variant with an average yield of 5.47 t/ha significantly exceeded the CT variant with the yield being 5.06 t/ha. Conversely, plants grown under STmp had significantly longer leaves than those under CT in BBCH 14–18 and with the highest values of all parameters, tended to faster growth of biomass, although the other differences were not statistically significant. No differences were observed between STmp and CT in BBCH 21 and 30. The STmp variant achieved the highest yield 5.53 t/ha, and significantly exceeded the CT variant.

The effects of plant density on the growth and yield of winter oilseed rape (Brassica napus) were examined in a series of five multifactorial experiments at Rothamsted Experimental Station between 1984 and 1989. Plant densities, manipulated by changing the seed rate and row spacing, or because of overwinter losses, ranged from 13·5 to 372 plants/m2. Normalized yields for the multifactorial plots increased with densities up to 50–60 plants/m2. In very high density plots in 1987/88, yield decreased as density increased >150 plants/m2. Plants grown at high density had fewer pod-bearing branches per plant but produced more branches/m2. Branch dry matter (DM) per plant was decreased by 42%, the number of fertile pods per plant and pod DM/plant by 37%. There was no effect of density on the number or DM of pods/m2. Over 74% of the fertile pods were carried on the terminal and uppermost branches of plants grown at high density in 1987/88 compared with only 34% in plants grown at low density in 1988/89. Seed DM/plant decreased with increase in density but seed size (1000-seed weight) increased. There was no effect of density on seed glucosinolate or oil contents.

Field trials were conducted in 2017 and 2018 wet seasons at Federal University Dutse Teaching and Research Farm (Latitude 11 46, 39”N and Longitude 9 20, 30”E) in the Sudan Savanna of Nigeria. To evaluate performance of sesame varieties as affected by poultry manure and weed control methods. The treatments consisted of five weed control treatments (pre-emergence application of ButachlorEC50%,  hoe weeding at 3WAS +pre-emergence butachlor EC50%, pre-emergence butachlor EC50%+hoe weeding at 3 and 6WAS, hoe weeding @ 3 and 6WAS and weedy check), three level of poultry manure (5, 10, and 15t/ha) and three sesame varieties (Ben 01, Yandev 55 and Ben 04E. The treatments were laid out in split plot design and replicated three times. The results indicated that weed control methods had significant effect (0.05) on the sesame growth and seed yield comparable to hoe weeding control at 3 and 6WAS where plant height number of leaves,  capsule number per plant and seed yield of sesame were significant higher with the application of butachlor plus hoe weeding at 3 and 6WAS compared to others weed control methods.  Poultry manure application on sesame as 15t/ha gave taller plant height, more number of leaves, higher sesame dry weight, longer capsule length and seed yield of sesame than the other rates while Ben 01(455 and 1043 ) perform better than the others two varieties (Yandev 498, 756 and Ben4E 522 and 765 ) for 2017 and 2018 seasons.  In conclusion,

The effect of N-S fertilizers on the molybdenum content in oilseed rape plants was investigated in precision field trials. Evaluation was carried out on unfertilized control and two treatments of single fertilizer rates in the first spring fertilizer application, using 100 kg N/ha in AN treatment (nitrochalk) and 100 kg N/ha + 50 kg S/ha in ANS treatment (ammonium nitrate and ammonium sulphate). The results confirmed the significance of sulphur fertilization for the winter oilseed rape plant’s cultivation technology, even on fertile soils in the CzechRepublic. The control treatment produced a yield of 3.7 t/ha, while in the AN treatment the yield was 49% higher, and the ANS treatment was 60% higher. An antagonistic relationship between the sulphate and molybdenum anions in their absorption by the plants was demonstrated. The molybdenum content in the flowering period of the plants was determined in mg/kg as follows – in the ANS treatment: 0.17 in root, 0.12 in stem, 1.56 in upper leaves, 0.90 in lower leaves, and 1.17 in the flower petals. Higher and statistically more significant molybdenum levels were determined in the AN treatment: 0.21 in the root, 0.19 in the stem, 2.40 in the upper leaves, 1.72 in the lower leaves, and 1.50 mg/kg in the flower petals. The total above-ground biomass of the plants in the flowering period had accumulated molybdenum at 6.06 g/ha in the ANS treatment, and 8.44 g/ha in the AN treatment.

The Impact

Abstract The effort to achieve higher yields at the required qualitative level has led to the intensive studying the problems of the rational usage of the titanium containing fertilisers by the agricultural research in the course the previous thirty years. Therefore, the objective of the experiment was to evaluate the impact of two doses of Mg-Titanit (0.2 l/ha and 0.4 l/ha) on the formation of the aboveground and underground phytomass, also on the total chlorophyll in leaves, on the titanium and nitrogen content in the seeds and straw, on the quantity and quality of winter rape yield. The doses were applied two or three times on the leaves of winter rape (BBCH 50-52, BBCH 59, BBCH 66-67). The experiment was realized on the Haplic Chernozem (48°42´ N, 17°70´ E - Western Slovakia) during two farming years (2009/2010 and 2010/2011). The results showed that all three applications of Mg-Titanit in both doses stimulated the formation of aboveground and underground phytomass of winter rape. The highest growth of phytomass was detected after the second application. The application of Mg-Titanit in the growth phases BBCH 50-52 and BBCH 59 increased the contents of both chlorophylls (a and b), where the growth of chlorophyll b content was more considerable than the growth of chlorophyll a content. The third spraying by Mg-Titanit decreased the content of the total chlorophyll. The application of Mg-Titanit had the positive impact on the yield of seeds, straw and fat content in the winter oilseed rape seeds.

To determine the effect of Organic-based Fortified Foliar Fertilizer (OFF) on the growth and yield of ‘Lakatan’ banana, this study was conducted at the University of Southeastern Philippines, Tagum – Mabini Campus, Mabini Unit, Mampising, Mabini, Compostela Valley Province, from December 2015 to March 2016.          The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF. Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana. The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control. The fruit weight of T6 – RR of NPK+ OFF has 61% higher than untreated and the yield of 37 tons/ha is higher than the national average yield of 9.4 tons/ha in ‘Lakatan’ banana.

Research was carried out at the Experimental Station of Aleksandras Stulginskis University on Calc(ar)i-Endohypogleyic Luvisol (LVg-n-w-cc) during 2014–2017. The effect of exogenous amino acids on the cold tolerance of the linear cultivar ‘Cult’ of winter oilseed rape (Brassica napus L. spp. oleifera biennis Metzg.) was studied. In autumn the plants were sprayed with L-proline and L-glutamic acid one or two times. The biometric parameters of winter oilseed rape prepared for wintering, the amount of endogenous proline and over-wintering of plants were evaluated. It was determined that exogenous L-proline and L-glutamic acid stimulated the growth of green mass of the winter rape surface, accumulation of dry matter and increase of the root neck diameter in the autumn period. The investigated concentrations of L-proline and L-glutamic acid stimulated a more intensive synthesis of endogenous proline in winter oilseed rape plants during the preparation for wintering. The highest percentage of over-wintering has been determined in the variants where in the autumn plants were sprayed two times with 30 mM l–1 L-proline or 1.5 M l–1 L-glutamic acid.

Strip Tillage

Microbes play vital roles in many soil ecosystem functions and services, which are crucial for agricultural productivity. Among different agricultural management practices, soil tillage methods can result in changes in a soil's physical, chemical and biological properties, including the soil microbiome. In addition, crop type and the plant developmental stage are important drivers of rhizosphere bacterial microbiota structure and composition. Here, we have used high-throughput, 16S amplicon sequencing to explore the rhizosphere bacterial structure and composition of Brassica napus (winter oilseed rape) in two contrasting tillage practices; conventional-plough based tillage and conservation strip tillage, over three different plant growth stages (vegetative, flowering and harvesting stage). This was the first year that conservation strip tillage was used in this field, as in previous years plough based tillage practices has been used. Our findings show that tillage and growth stages were important determinants of microbial community structure and composition, but the effect of tillage became stronger at plant maturity. The combined effect of conservation strip tillage and harvesting stage had a impact on the rhizosphere microbiota selection. The rhizosphere bacterial community of winter oilseed rape under conservation strip tillage was different to that under conventional tillage. Our data suggests that different tillage regimes created distinct ecological niches that selected different microbiota with potential consequences for the ecosystem services provided to the plants and the soil environment.

Field trials were conducted at University Organic–Agriculture farm, Federal University of Agriculture Abeokuta in 2011 to determine the response of different mulching materials on growth and yield of okra. It was a 3x3 factorial laid out in Randomized Complete Block Design (RCBD) with the main factor as the plant material Chromolaena odorata (CO) Glycine max (GM) and Panicum maximum ( PM) while rate ( 0, 5 and 10t/ha) of mulching materials were applied once before the first cropping was the sub-factor and all were replicated three times. Data were collected on growth parameters and yield attributes of okra (NHAE- 47-4) at first and second planting. The parameters assessed were significantly influenced (P <0.05) by the mulching material and rate of application. Higher values for plant height ( 56.3cm and 60.7cm ) , number of leaves ( 22 and 22) and stem girth (1.5cm and 2.1cm) at 16 weeks after planting (WAP) were obtained during the first and second planting from CO application of 10t/ha. Although, the higher number of flowers ( 14 and 21), number of pods ( 29 and 21) and weight of pods/plant (0.51kg and 0.44kg) were derived from PM when 10t/ha was used at 16 WAP during both plantings. Thus, optimum okra yield were obtained with application of 10t/ha of plant residues, therefore, mulching with PM residues at 10t/ha is recommended for high fruit yield of okra in the region of investigation.
