Crop establishment methods: foliar and basal nourishment of rice ( Oryza sativa ) cultivation affecting growth parameters, water saving, productivity and soil physical properties uri icon

abstract

  • A 3-year field experiment was carried out with tillage crop establishment (TCE) and rice nourishment in north-western India to evaluate the effect of five crop establishment methods and seven fertility treatments on crop production, water productivity, profitability, and soil physical quality. Maximum panicle length (30.9 cm) was noted with F-3 treatment and minimum (22.7 cm) with F-0 treatment. Zinc application methods and timing had significantly effect on paddy yield. Maximum yield (5.22 t ha(-1)) was achieved in treatment F-3 and minimum yield (2.65 t ha(-1)) was noted in F-0 treatment. Results also revealed that root dry weight, root volume, and root length were recorded with higher values in F-3 treatment and minimum in F-0 treatment. TCE methods were recorded with higher values in raised beds system than T-5 at all growth stages. Treatments T-1 and T-2 reduced the mean maximum soil temperature at transplanting zone depth by 3.6 and 2.7 A degrees C compared to the T-3. Paddy yield in T-3 was always significantly less than in T-5. On average, treatment T-4 recorded about 13 % lower water use and 3.7 % higher water productivity compared to T-5. Treatment T-5 had higher bulk density. The cumulative infiltration for 498 min was about 2 times in treatment T-1, 5 times in T-3 and more than 8 times in T-4 of the values in T-5. Mean weight diameter of aggregates was higher in T-4 followed by the T-1 and lowest in T-5. The study reveals that TCE methods T-1 and T-4 with F-3 nourishment could be more viable options for rice crop in order to save input costs and enhance profitability.
