Consequences of nano nutrients and different fertility levels on productivity of late sown wheat (Triticum aestivum L.)


Mahesh Kumar, SC Meena, R H Meena and Somdutt

A field experiment was conducted at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur during rabi season of 2019-20 to find out effect of nano-nutrients and different fertility levels to study their effect on productivity of late sown wheat. The experiment was conducted in clay loam soil which was low in available nitrogen, medium in phosphorus and high in potassium. The results revealed that the application of different fertility levels and spray of nano P, K and Zn at various stages of late sown wheat has significantly influenced the growth and yield characters viz., plant height and dry matter, effective tillers, number of grains ear-1, test weight, grain, straw and biological yield etc. and also increased nutrient concentration of plant and soil sample. The maximum plant height (114.86 cm), maximum dry matter accumulation (50.09 g plant-1) at 45 DAS and (224.07 g plant-1) at harvest, chlorophyll content of flag leaf was 2.417 mg g-1 of fresh leave weight was recorded with the treatment application of T7, which was not differing significantly with the treatments T8 and T10. The maximum number of effective tillers meter-1 row length (82.05), number of grains ear-1 (41.70), test weight (55.84 g) and yield of wheat crop grain (4832.5 kg ha-1), straw (6958.3 kg ha-1) and biological yield (11790.8 kg ha-1) under the treatment application of T7, which statistically at par with T8, T9 and T10. The highest gross and net return 113901 and 84193 ` ha-1 respectively and benefit cost ratio of 2.83 was gained under the application of treatment T7, which was statistically at par with the treatment T10.
