EZ-N AND NUTRICHARGE RICE STUDY

Updated: Feb 22



1. Objects and methods of research

Study with the aim of optimizing fertilizer efficiency and yields of rice using NutriCharge and EZ-N nitrogen stabilizer with phosphorus and nitrogen fertilizers. The study was conducted at a government sponsored rice institute.

Soil test:

  • Organic Matter - 3.2-3.8%;

  • Total Nitrogen - 0.21-0.34%,

  • Total Phosphorus- 0.23%,

  • Total Potassium - 0.91%,

  • pH- 6.7-7.8,

Rice variety Nautilus, mid-season variety (vegetation period 113-115 days), moderately resistant to blast and shedding, plant height 90-100 cm, panicle 17-18 cm long, caryopses rounded.

Quality of cereals: weight of 1000 grains - 28-29 g, glassiness 96-98%, the total yield of cereals is 71-72%, the whole kernel in cereals is 85-90%.


Researched Products - NutriCharge and EZ-N


Experimental plots:

  1. 12-52-0 + Urea (main);

  2. 12-52-0 with NutriCharge 0.5 GAL/TON (main) + Urea with EZ-N (33 OZ/TON) (main);

  3. 12-52-0 (main) + Urea (main) + Urea (top dressing);

  4. 12-52-0 with NutriCharge 0.5 GAL/TON (main) + Urea (main) +Urea (top dressing);

  5. 12-52-0 with NutriCharge 0.5 GAL.TON + Urea with EZ-N (33oz/ton) (main) + Urea with EZ-N (33oz/ton) (top dressing).

Replications-three

Plot size-1000 sq. ft .

The introduction of nitrogen and phosphorus fertilizers is carried out following standard grower practice: nitrogen (urea) 200 lb./acre, phosphorus (12-52) 90 lb./acre.


Fertilization timing:

  • Before sowing (main) - May 03

  • Sowing rice - May 08

  • Fertilizing with nitrogen - June 11 100 lb./acre

  • Fertilizing with nitrogen - July 01 100 lb./acre

  • Flood to germinate - May 11

  • Separate harvesting. Mowing rice into rolls (20.09.21), threshing rolls September 23-24

For all experiment variants, 90 lbs/acre of 12-52-0 was applied before sowing, and 100 lb/acre of urea, top dressing with urea 100 lb/acre carried out in the tillering phase.


Sowing rate - 205-222 lb/acre.


Application of nitrogen and phosphorus fertilizers treated with Nutricharge and EZ-N was performed before rice sowing (May 03). Nitrogen top dress during the germination and tillering phases.


The rice yield was taken into account on a plot basis with the obtained data to the standard indicators for purity (100%) and grain moisture (14%).



Research results

One of the conditions for ensuring the planned yield of rice is getting uniform shoots. Sowing with minimal incorporation of seeds and a shortened irrigation regime increases field germination of seeds. The use of agricultural practices to improve growth processes is the basis for increasing rice plants' productivity.


Nitrogen Sufficiency

The level of supply of plants with nitrogen nutrition helps indicate productivity.
