Diverse farming systems and their impact on macro and microelement content of vegetables & crops

Agriculture plays a vital role in the economy of any country. In this data agriculture activities are described in term of nutritional value of crops and vegetables in North India, Haryana. Crops and vegetables according to the climate of Haryana were shown in a field from 2019 to 2021 according to sowing season of each Rabi and Kharif crops. There were six seasons in three years. Four plots of 8.0 m × 8.0 m each of organic as well as conventional were used for sowing. Crops were chosen on the basis of their suitability to the climate of north India. Rabi crops included peas (Pisum sativum), berseem (Trifolium alexandrinum), mustard (Brassica nigra), onion (Allium cepa), fenugreek (Trigonella foenum graecum) and potatoes (Solanum tuberosum). Kharif season included millet (Pennisetum glaucum), sesame (Sesamum indicum) and sorghum (Sorghum bicolor). From each season, crops were harvested and subsequently, their macro and micronutrient analysis were carried out. The comparison of macro elements such as K, P, Na, Ca, S and Mg and microelements Mn, Fe, Cu, Al, Zn and B in organic vs. conventional farming at the end of each season each year was done. Samples were prepared with the help of wet digestion method and then analysed by element analyzer and ICP-OES (Inductive coupled plasma optical emission spectrophotometer).Descriptive statistics were performed using Graph Pad Prism software at a significance level of ≤ 0.05. Figures were plotted with Microsoft Excel. Data shows that mean of macroelements like potassium(3533 mg/kg), phosphorus( 282 mg/kg), magnesium(176 mg/kg) ,sodium( 282 mg/kg),sulphur( 390 mg/kg) and calcium(188 mg/kg) was found more in each mineral in case of organic farming as compared to conventional farming that are K(3317 mg/kg),P(240mg/kg),Mg(143 mg/kg), Na( 237 mg/kg), S ( 273 mg/kg) and Ca( 153 mg/kg).All data were calculated in term of mean, standard deviation and minimum and maximum value of minerals present in the crops and vegetables. Also, microelements mean in organic farming was found to be more Mn(2.12 mg/kg ),Cu( 0.670 mg/kg), Fe(4.16 mg/kg ), Al( 1.65 mg.kg),Zn(2.13 mg/kg) and B(1.65 mg/kg) as compared to conventional farming that contain Mn (0.787 mg/kg),Cu (0.393 mg/kg), Fe (2.48 mg/kg), Al (0.933 mg/kg), Zn (1.57 mg/kg) and B(0.593 mg/kg).So different macroelements and microelements can be analysed in organic as well as conventional farming to show that organic farming with the help of organic fertilizers like vermicompost and
