International Journal of Environment and Climate Change

The study in relation to “Impact of nutrient management on soil chemical properties and Maize (Zea mays L.) yield” was conducted during the year 2021-22 at Vizianagaram district of Andhra Pradesh. Application of optimal doses of inorganic and organic fertilizers to maize at 5 t FYM ha-1 yearly containing 126:58:45 NPK kg ha-1 and 17 kg Zn ha-1 with highest maize yield of 65.00 q ha-1 as compared to the farmers lower yield of 47 q ha-1 without the optimum dose of inorganic and organic fertilizers to maize. Soils of the study area were acidic to neutral in soil reaction, non-saline and non-calcareous in nature, low in organic carbon in both surface and sub-surface layers.

Productivity, Leaf Nutrient Content and Soil Carbon Stocked in Agroforestry and Traditional Management of Maize ( Zea mays L.)

American Journal of Plant Sciences, 2014

The aim of the work was to evaluate the productivity, leaf nutrient content and soil nutrient concentration in maize (Zea mays L.) grown in sequence with black oats (Avena strigosa Schreb.) under Leucaena diversifolia alley cropping agroforestry system (AFS) and traditional management system/sole crop (without trees-TS), after two years of cultivation following a randomized block design. The experiment was carried out in the Brazilian Association of Biodynamic Agriculture, in Botucatu-São Paulo, Brazil. Treatments were: control (C), chemical fertilizer application (F), biomass of L. diversifolia alley cropping application (B), biomass of L. diversifolia alley cropping + chemical fertilizer application (B + F). In the second year of management it was observed that black oat yield was higher in treatments B + F and F with significant difference in relation to the others treatments in both systems, followed by treatment B. Between systems, only treatment B showed significant difference, with higher yield value corresponding to AFS, reflecting the efficiency of AFS to promote soil fertility. Maize production presented the second year of cultivation an increasing trend in all treatments in both production systems. This result may be due to the cumulative effect of mineralization and maize straw and oats, along the experiment. How productivity was higher in the AFS system, could also be occurring effect of biological nitrogen fixation, water retention and reduction of extreme microclimate through the rows of L. diversifolia. Comparing the AFS and TS, it was observed that the concentration of N in leaf tissue was higher in the AFS treatments, probably due to nitrogen fixation performed through the rows of L. diversifolia, that is a nitrogen fixing tree species. After two years, carbon stocked in soil show higher values in the treatments biomass + fertilizer and biomass application, in both systems, AFS and TS.

Soil fertility is a major challenge depressing yields in small hold farms of Sub-Saharan Africa. Growth and yield parameters are key indicators of soil fertility status in most agro ecosystems. A study was conducted in Murang’a County Kandara Sub-County in Kenya. This was to determine the effects of applying different nutrients on growth and yield of maize. The study was done in 2013 during the long rains season (LR13) and the short rains season (SR13). Twenty-three farmers were randomly selected for the study. The experiment was laid out in randomized complete block design (RCBD) with 8 treatments (control, NPK+ CaMgS micronutrient fertilizer (Ca, Mg, S, B, Mn, Cu, Zn,), NPK+ Manure, NPK+ Lime, NPK, NP, NK, and PK). Soil was sampled before establishment of the trials at a depth of 0–20 cm. The soil samples were analyzed for pH, total carbon, macro, and secondary nutrients. Treatment inputs were applied at rates of 100 kg ha-1 N, 30 kg ha-1 P, 60 kg ha-1 K, 10 kg ha-1 Ca, 10 kg ha-1...

Effect of Integrated Nutrient Management on Growth and Yield Parameters of Maize (zea mays l.) As well as Soil Physico- chemical Properties

BJSTR, 2017

A field experiment was conducted during the winter season of 2013 at a main research field of the School of Agriculture Lovely Professional University, Phagwara, Punjab (India) to study the influence of integrated nutrient management on growth and yield parameters of maize (Zea mays l.) as well as soil physico-chemical properties. The growth parameters (plant height and leaf area) were found to be highest under INM (Integrated Nutrient Management) of poultry manure (PM) or farm yard manure (FYM)and recommended dose of fertilizers (RDF) which are statistically on par but comparatively higher than T₁ (100% RDF). The yield parameters (number of grains per cob, cobs weight per plant, Test weight and stover yield) were significantly higher under INM compared to T₁ (100% RDF). Furthermore, post harvest soil physico-chemical properties (organic carbon and available nitrogen) were significantly improved under T₃ (5t PM + 50% RDF), whereas soil available phosphorus was recorded maximum under T₅ (5t PM + 100% RDF) compared to control and rest of the treatments combination. Therefore, the integration of 50% RDF along with either 5 t/ha FYM or PM or both resulted in maximum maize productivity on par compared with sole used of 100% RDF.

Influence of site-specific nutrient management on growth and yield of maize (Zea mays) under conservation tillage

A field experiment was conducted at New Delhi during rainy (kharif) season of 2013, to study the effect of nutrient management on growth and development behaviour of maize (Zea mays L.) hybrids. Normalized difference vegetation index (NDVI), SPAD value, dry-matter accumulation, leaf-area index, crop growth rate (CGR) and relative growth rate (RGR) were significantly higher with site-specific nutrient management (SSNM) over the recommended dose of fertilizer (RDF) under conservation agriculture. Of the maize–genotypes ‘CMH 08-292’ recorded significantly highest dry-matter accumulation at various stages and CGR, while ‘PMH 1’ recorded higher NDVI, SPAD, leaf-area index and RGR. Cobs/plot, cob length and girth, grain rows/cob, grains/row, cob yield, shelling, harvest index and grain yield were significantly higher with SSNM over RDF. ‘PMH 3’ recorded significantly higher cobs/plot, cob length and girth, grains/row, cob yield and grain yield, whereas ‘S 6217’ recorded significantly higher grain rows/cob and harvest index, while significantly higher shelling was recorded with ‘CMH 08-292’.

ABSTRACT Soil fertility is a major challenge depressing yields in small hold farms of Sub-Saharan Africa. Growth and yield parameters are key indicators of soil fertility status in most agro ecosystems. A study was conducted in Murang'a County Kandara Sub-County in Kenya. This was to determine the effects of applying different nutrients on growth and yield of maize. The study was done in 2013 during the long rains season (LR13) and the short rains season (SR13). Twenty-three farmers were randomly selected for the study. The experiment was laid out in randomized complete block design (RCBD) with 8 treatments (control, NPK+ CaMgS micronutrient fertilizer (Ca, Mg, S, B, Mn, Cu, Zn,), NPK+ Manure, NPK+ Lime, NPK, NP, NK, and PK). Soil was sampled before establishment of the trials at a depth of 0–20 cm. The soil samples were analyzed for pH, total carbon, macro, and secondary nutrients. Treatment inputs were applied at rates of 100 kg ha-1 N, 30 kg ha-1 P, 60 kg ha-1 K, 10 kg ha-1 Ca, 10 kg ha-1 Mg, 5 kg ha-1 S, 10 t ha-1 manure and 1 t ha-1 lime. Data on maize plant height, leaf number, and basal diameter was collected at 14, 28, 42, 56 and 70 days after planting (DAP). Grain and stover yield was collected at physiological maturity. The results showed that control, PK and NK treatment achieved means that were significantly different (p<0.05) for leaf number and bio-volume during the 2 cropping seasons. The grain and stover yields for control, NK and PK showed significant differences (p<0.05) during the two cropping seasons. Simple linear regression analysis between grain yield and leaf number achieved a coefficient of determination (R 2) of 0.9 during both seasons. The coefficient of determination (R 2) between bio-volume and grain yield at 42 DAP was 0.8 for LR13 season and 0.9 for SR1, respectively. The yield response to nitrogen application was 1.87 Mg ha-1 in the LR13 season and 1.90 Mg ha-1 during the SR13 season. The yield response (yield loss) for phosphorus was 0.84 Mg ha-1 in the LR13 season and 0.81 Mg ha-1 during the SR13 season. It was concluded that absence of N and P nutrients significantly affects maize leaf number and bio-volume and eventually these effects influence the achieved grain yield. The results of the study show the need to adopt specific nutrient application instead of the former use of blanket recommendation for whole regions.

Influence of different organic and inorganic sources of nutrients on maize (Zea mays)

A field experiment was conducted at Breeder Seed Production farm of Mahatma Phule Krishi Vidyapeeth, Rahuri, during the rainy (kharif) seasons of 2011 and 2012, to find out most efficient and economic combination of different organic and inorganic sources of nutrients to increase the productivity of hybrid maize (Zea mays L.) without deteriorating the soil qualities. Integrated application of 25% recommended dose of fertilizers (RDF) with biofertilizers (Azotobacter chroococcum + phosphate-solubilizing bacteria), green-manuring with sunhemp (Crotalaria juncea L.) and incorporation of compost @ 10 tonnes/ha improved soil physico-chemical properties, viz. pH, bulk density and infiltration rate, and the nutrient status of soil in respect of organic carbon, available N and available P. Maize grain yield was increased by 252.38% over the control and 147.62% over application of 100% RDF with combined use of organic and inorganic fertilizers, which was 7.4 tonnes/ha with highest gross returns ( 95.9 × 103/ha) and net returns ( 54.2 × 103/ha). Maximum benefit: cost ratio (1.30) was also observed in combined use of 25% RDF, compost, biofertilizers and green manuring and it was followed by application of 100% RDF (1.26), which was responsible for deterioration of nutrient status of soil.
