Nitrogen Additions

Nitrogen additions to high C:N yard wastes improve the composting process and the usefulness of the product. Nine composts were made with additions of 10 or 25% grass clippings or poultry manure (PM) and several composting methods (in bin, turned, static). Turnip, tomato, watermelon, snap bean, and lettuce seeds were germinated, and some were grown to maturity in pots. The 25% PM compost delayed germination of turnips and beans by 2 days, but final germination % was not affected. Germination of melon (27%) was significantly less with 25% PM than with other composts. Tomato germination was not affected by any treatment, but dry weight of 4 week old seedlings grown in PM treatments was 4 times greater than other treatments. Pod yield of beans grown in 10% PM compost was equal to beans grown in potting mix with soluble fertilizer.

Recognition of high yielding and nitrogen (N) fixing groundnut genotypes and desegregating them in the cereal-based cropping systems common in savannah regions will enhance food security and reduce the need for high N fertilizers hence, minimize the high cost and associated environmental consequences. Field trials were conducted during the 2015 growing season at the Research Farms of Bayero University Kano (BUK) and Institute for Agricultural Research (IAR), Ahmadu Bello University, Samaru-Zaria to assess the yield potential and Biolog- ical N fixation in 15 groundnut genotypes (ICG 4729, ICGV-IS 07823, ICGV-IS 07893, ICGV-IS 07908, ICGV- SM 07539, ICGV- SM 07599, ICGV-IS 09926, ICGV-IS 09932, ICGV-IS 09992, ICGV-IS 09994, SAMNUT-21, SAMNUT-22, SAMNUT-25, KAMPALA and KWANKWAS). The groundnut genotypes and reference Maize crop (SAMMAZ 29) were planted in a randomized complete block design in three replications. N difference method was used to estimate the amount of N fixed. The parameters determined were the number of nodules, nod- ule dry weight, shoot and root dry weights, pod, and haulm yield as well as N fixation. The nodule dry weight, BNF, haulm, and pod yield were statistically significant (P<0.01) concerning genotype and location. Similarly, their interac- tion effect was also highly significant. ICGV-IS 09926 recorded the highest nod- ule dry weight of 2.07mg /plant across the locations while ICGV-IS 09932 had the highest BNF value of 140.27Kg/ha. Additionally, KAMPALA had the high- est haulm yield, while ICGV-IS 07893 had the highest pod yield across the loca- tions with a significant interaction effect. The result shows that ICGV-IS 07893 and ICGV-IS 09932, as well as ICGV-IS 09994 and SAMNUT – 22, were the best genotypes concerning BNF, haulm and pod yield in the Northern Guinea and Sudan Savannahs of Nigeria respectively with the potential for a corresponding beneficial effect.

Tomato was grown in Fall 1997 with swine effluent or commercial soluble fertilizer in a plasticulture production system. Four cultivars, `Mountain Delight', `Celebrity', `Equinox', and `Sunbeam', were transplanted to raised beds with plastic mulch and drip irrigation. Preplant fertilizer was not applied. Effluent from the Wiley L. Bean Swine Demonstration Unit's secondary lagoon was filtered through in-line screen filters and applied directly to the plants through the irrigation system. Toward the end of each application, sodium hypochlorite was injected in the line to achieve a free chlorine concentration of ≈1%. Clogging of filters or drip emitters did not occur. Control plants received 100 ppm N from soluble fertilizer injected in irrigation lines supplied by a municipal water source. Number and weight of tomatoes from plants receiving swine effluent were equal to that of plants receiving soluble fertilizer. No differences in fruit quality were evident between treatments. Plant dry weight was also equal for three out of four cultivars. No differences in soil characteristics were detected between treatments after the study. Chemical analysis of the effluent showed a pH of 7.8 and nutrient concentrations of ≈110 ppm NH4-N, 57 ppm P2O5, 150 ppm K2O, and trace amounts of Cu and Zn. Though no differences in yield were detected in this study, the effluent's high pH and high NH4-N content need to be managed more closely for commercial tomato production.

The Study was conducted to evaluate the effect of solid and liquid organic fertilizer on growth and yield of rosselle in 2016 cropping season at Institute of Agricultural Reserve Zaria, Samaru (11011’N 07038E and 686m) and Institute of Horticultural Research Farm Bagauda (12000’N 8031”Em 488m) in Northern Guinea Savannah and Sudan Savannah Ecological Zones of above sea level Nigeria. Treatments consisted of four levels of solid poultry manure (0.0, 1.0, 2.0 and 3.0) tons/ha and five levels of liquid organic manure from Grand Total Organic Fertilizer Limited (0.0, 0.5, 1.0, 1.5 and 2.9) litres/ha, which were factorially combined in a randomized complete block design (RCBD) and replicated three times. Data on growth parameter were collected on plant height (cm), plant dry weight (g), leaf Area index crop growth rate (CGR) Relative Growth Rate (RGR) and Net assimilation rate (NAR) while data on yield parameters like number of calyx per pant, 100 seed weight (g) and  calyx yield per hectare kg/ha were collected. Results showed that plant height, plant dry weight(g), 100 seed weight(g) and calyx dry yield kg/ha had a significant increase with application of 2.0 litres/ha of liquid fertilizer than other rates. While application of solid poultry manure at 3.0ton/ha significantly increases plant height, net assimilation rate, leaf area index and calyx dry weight when compared with other rates. From the results obtained, the combination of 2.0 litres/ha liquid organic fertilizer and 3.0 ton/ha solid poultry manure produce the highest calyx yield at both location.

This research aimed to identify colchicine-induced tropical Yellow Corn characters and their potential in superior traits development. Single cross was applied to colchicine mutant line with tester line, INOAXM2 yellow and white seeds, to observe and test the characters enrichment of colchicine mutant, while pure line tester of sweet corn (OP-SBX) was used to observe the enhancement of germination and growth rate. Analysis of various quantitative data was determined using F test at the level of 5%, continued with Least Significant Difference Test (LSD) at the level of 5%. Potential characters and its inheritance pattern were determined by a descriptive statistical approach. Overall, germination and growth test of mutant show significant improvement when mutant crossed with tester lines. According to qualitative characters analysis of mutant line and its single way, it is found that glum colour is influenced by the male parent (Paternal Effect), while seed colour is determined by the female (Maternal Effect). From mutant M1 to M4, quantitative mutant (INFM) characters showed significant differences between lines within one generation and revealed improvements in single cross progeny. Single cross between colchicine line and tester mutant (IONAXM2) presents significant differences in all cobs characters (cob length, number of seeds in a row, number of rows, cob dry weight, and weight of 100 seeds (g) and reveals higher value compared to other lines. Mid-parent heterosis of single cross progeny of mutants was high for cob dry weight, those were 202.38% and 166.67%. The chromosomes observation of pink and yellow seeds of colchicine mutants revealed the presence of diploid, triploid, and euploid chromosomes, which verify chromosomal changes inside colchicine mutant lines.

A laboratory study was conducted to assess the herbicidal potential of root exudates of three rice cultivars (ADT-36, BPT and IR-20) against germination and growth of common crop field weed, barnyard grass (Echinochloa crus-galli L.). Various concentrations (5, 10, 15 and 20%) of root exudates were prepared from the underground part of rice cultivars from the postharvest rice fields. The studies revealed that all the three rice cultivars were exhibited significant inhibition on growth and development of weed species. Among the rice cultivars, ADT-36 exhibited the greatest inhibition on the seed germination (86%), seedling growth(83%), dry weight (81%) of barnyard cross than BPT and ADT-36. The percentage of inhibition on concentration depends. The order of inhibition of the rice cultivars was ADT-36 > BPT > IR-20 on barnyard grass.

The field experiment was undertaken at the District Seed Farm, Kalyani at Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during summer season of 2012 and 2013 to study the growth and yield of summer groundnut as influenced by application of water soluble foliar grade fertilizer. Application of liquid grade fertilizerat early growth stage up to 45 DAE did not influence the plant height and dry matter production significantly, but towards maturity varied significantly (P ≤ 0.05). Crop growth rate was faster at early part of the crop age and gradually slows at later part towards maturity. Foliar application of water soluble fertilizer along with RDF 85% had the significant (P ≤ 0.05) influence to increase the number of pods per plant, but shelling percentage and hundred kernel weight did not vary significantly. Liquid grade fertilizer either starter dose or booster dose or in both had the positive response to increased the groundnut pod yield up to 4-6 % over RDF only. The crop was equally responsive in increasing the pod yield, when RDF was reduced by 15% along with foliar application of liquid grade fertilizer. The foliar application of water soluble fertilizer was not the substitute to soil applied inorganic fertilizer. Instead, foliar supplementation of nutrients showed positive response to increase the pod yield, in addition to the fertilizers added to soil. Gross return decreased with reduction in amount of RDF applied for the crop, but gross return increased, when water soluble foliar grade inorganic fertilizer was supplemented with RDF. The maximum gross return of `150399 was obtained. The results obtained from correlation analysis carried out to examine the linear relationship between pod yields with different plant characters. Data obtained in case of dry matter of the plant was 0.995 and 0.997 in the respective years at 1% level of significance. Thus, it was concluded that dry matter content of plant is solely responsible over the yield increase in groundnut and foliar application of inorganic fertilizers in addition to that in soil has helped in better adsorption of nutrients in adequate amount by the crop.

Hot pepper is an important vegetable and spice crop in Ethiopia. However, the productivity of hot pepper is limited by poor soil fertility and lack of proper soil and water conservation measures under irrigated condition. Therefore, hot pepper crop response to nitrogen (N) fertilizer and mulching experiment was conducted at Alage ATVET College. The treatments consisted of three mulch types (no mulch, transparent plastic mulch, and dry banana leaves mulch) and four levels of N (0, 50, 100 and 150 kg N ha-1) factorial arranged in a randomized complete block design with four replications. A hot pepper cultivar commonly known as “MarekoFana” was used for the study. Days to 50% flowering, 50% fruit set, maturity and harvest were significantly prolonged in response to increasing N application. The delays were about 7, 19, 23 and 12 days at the N levels of 50, 100 and 150 kg N ha-1respectively compared to the control. The analysis of variance revealed that plant height, number of branches per plant, number of pods per plant, dry weight of seeds per pod, total weight of dried pods per plant, weight of individual dry pods and width were significantly (P = .001) increased by the main effect of mulching. Generally, the results revealed that nitrogen application significantly (P = .001) influenced all growth parameters, pod yield, and yield components of the crop. Nitrogen application at 100 kg ha-1 resulted in the highest total dried pod yield (4.5 tha-1), marketable yield (3.76 t ha- 1), pod length (13.3 cm), pod width (3.2 cm), mean dry weight of pod (3.85 g), and seed number per pod (108.4). The interaction of N and mulching also significantly (P = .05) affected marketable and total pod yields. In conclusion, based on agronomic performance and partial budget analyses results we recommend a combined application of dry banana leaves mulch and 100 kg N ha-1 for economically feasible and sustainable hot pepper production in Alage areas of Central Rift Valley of Ethiopia.

1. The distribution of phospholipase D (phosphatidylcholine phosphatido-hydrolase, EC 3.1.4.4) was examined in the tissues of a number of plants and seeds. 2. The highest activities were found in various swollen storage tissues of certain plants: cabbage, central stalk; cauliflower, flower; celery, swollen leaf stalk; Kohl rabi, swollen stem; carrot, root; pea and marrow, seed. 3. Appreciable activity was retained in pea seeds for at least 1 year after drying. After germination and growth in the dark the total activity present in the cotyledons and also in the whole seedling decreased. 4. In the growing pea seedling (7 days old), about 3% of the total activity was in the plumule, 9% in the root and the remainder in the cotyledons. However, the activity in the root on a dry-weight basis was higher than that in the cotyledons. In both the root and the plumule the activity on a wet- or a dry-weight basis was highest in the growing tip. 5. The activity per dry weight in the roots and aerial parts of pea plants declined to low values as growth continued, but roots struck from cuttings of mature plants showed the same high activity as found in roots from young seedlings with cotyledons attached. 6. The total phospholipids present in the cotyledons of pea seeds were depleted on germination and growth. Of the individual phospholipids, phosphatidylcholine and phosphatidylethanolamine showed the same loss in 11 days as the whole phospholipid fraction, whereas phosphatidylinositol was decreased to a greater extent and cardiolipin and phosphatidylserine were not decreased. There was no increase of phosphatidic acid, as might have been expected if the phospholipids had disappeared through phospholipase D hydrolysis. 7. It is concluded that phospholipase D in plant storage tissues and seeds may be related to the rapid growth involved in their formation rather than being necessary for the utilization of their food reserve substances.

In the greenhouse, glyphosate [N-(phosphonomethyl)glycine] at 0.6 kg ae/ha applied directly to seeds alone or seeds on the soil surface reduced germination and shoot dry weight of common rye (Secale cerealeL. ♯3SECCE). Paraquat (1,1′-dimethyl-4,4′-bipyridinium ion) applied similarly at 0.6 kg ai/ha reduced germination and shoot dry weight of downy brome (Bromus tectorumL. ♯ BROTE) and wheat (Triticum aestivumL. ‘Daws' ♯ TRZAX). Metribuzin [4-amino-6-tert-butyl-3-(methylthio)-as-triazin-5 (4H)-one] at 0.6 kg ai/ha applied to seeds, soil, or seeds and soil had very little effect on germination, but significantly reduced shoot dry weight of common rye, downy brome, wheat, and jointed goatgrass (Aegilops cylindricaHost. ♯ AEGCY). Pronamide [3,5-dichloro(N-1,1-dimethyl-2-propynyl)benzamide] at 0.6 kg ai/ha, and propham (isopropyl carbanilate) at 3.4 kg ai/ha plus extender (p-chlorophenyl-N-methylcarbamate) at 0.4 kg ai/ha substantially reduced shoot height and dry weight of all species, regardless of application method, with pronamide completely inhibiting shoot elongation and dry-weight production in three of the four species.
