dc.description.abstractABSTRACT Capsicum and cabbage are the two most important vegetable crops grown in the Western Himalayas, have potential to strengthen the economic conditions of hilly small and marginal farmers. The present studies titled, “Response of nano-particles (TiO2) with different nutrient source combinations on capsicum-cabbage cropping sequence” was carried out at the research farm of Department of Soil Science and Water Management, Nauni, Solan, during 2020–2022. The research trials comprehend of thirteen treatments comprising T1 as control i.e., 100% RDN through chemical fertilizers, from T2 to T13 contains 100% RDN through chemical fertilizers and in combination of 50% RDN through chemical fertilizers and 50% RDN through vermicompost (on nitrogen equivalence basis) along with TiO2 application as seed treatment and foliar spray with concentration of 50, 100 and 150 ppm for capsicum and 500, 1000 and 1500 ppm for cabbage. The treatments were replicated thrice in randomized block design. The data revealed that the application of various nutrient sources combined with nanoparticles (TiO2) as seed treatment or foliar spray significantly influenced plant growth, yield, quality parameters, total NPK contents and their uptake in both crops. For cabbage crop, the application of 1000 ppm TiO2 as seed treatment along with conjoint application of chemical fertilizers and vermicompost enhanced plant height, plant spread, net head weight, harvest index, marketable yield, protein, chlorophyll a & b, total N content and N uptake. In capsicum the 100% RDN (50% through chemical fertilizers and 50% through vermicompost) along with application of nanoparticles (TiO2) concentrations of 50 ppm as seed treatment enhanced ascorbic acid, protein, chlorophyll a & b, Total N, P, K, Fe and Zn content. Among soil parameters, maximum value of organic carbon, available macronutrients and micronutrients were recorded in 150 ppm (capsicum) and 1500 ppm (cabbage) TiO2 applications. Soil microbiological properties were significantly influenced by the TiO2 application with integrated nutrient management module. The heavy metals in soil registered declined trend due to TiO2 applications in comparison to control. The maximum (3.76) B:C ratio was noted in treatment with 1000 ppm TiO2 as seed treatment in cabbage and 100 ppm TiO2 as foliar spray in capsicum (2.59) along with chemical fertilizers application. In order to improve the productivity of capsicum and cabbage cropping sequence without deteriorating soil health, the above-mentioned nutrient module may be recommended after carrying out multi-locational trials in mid hills of Himachal Pradesh for successful adoption of nanoparticles in the agricultural fielen_US
