Crop establishment methods: foliar and basal nourishment of rice (<Emphasis Type="Italic">Oryza sativa</Emphasis>) cultivation affecting growth parameters,water saving,productivity and soil physical properties

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 F₃ treatment and minimum (22.7 cm) with F₀ treatment. Zinc application methods and timing had significantly effect on paddy yield. Maximum yield (5.22 t ha^?1) was achieved in treatment F₃ and minimum yield (2.65 t ha^?1) was noted in F₀ treatment. Results also revealed that root dry weight, root volume, and root length were recorded with higher values in F₃ treatment and minimum in F₀ treatment. TCE methods were recorded with higher values in raised beds system than T₅ at all growth stages. Treatments T₁ and T₂ reduced the mean maximum soil temperature at transplanting zone depth by 3.6 and 2.7 °C compared to the T₃. Paddy yield in T₃ was always significantly less than in T₅. On average, treatment T₄ recorded about 13 % lower water use and 3.7 % higher water productivity compared to T₅. Treatment T₅ had higher bulk density. The cumulative infiltration for 498 min was about 2 times in treatment T₁, 5 times in T₃ and more than 8 times in T₄ of the values in T₅. Mean weight diameter of aggregates was higher in T₄ followed by the T₁ and lowest in T₅. The study reveals that TCE methods T₁ and T₄ with F₃ nourishment could be more viable options for rice crop in order to save input costs and enhance profitability.
