| dc.description.abstract | An ongoing long-term field experiment established in 1967 on coarse loamy soil on research farm of Department of Soil Science, CCS Haryana Agricultural University, Hisar (India) was selected to study the effects of various modes and levels of FYM and fertilizer N on soil properties and crop productivity under pearl millet-wheat crop rotation. The experiment was laid out in split plot design consisted of 3 levels and 3 modes of FYM application in main plot and 2 levels of fertilizer N in sub-plot. The plant and soil samples were collected during and after 51 cycles of pearl millet-wheat cropping system. The results revealed that application of FYM alone or in combination with fertilizer N decreased the soil pH as compared to initial value but soil EC showed the reverse trend. The soil organic carbon (SOC), dissolved organic carbon (DOC) and available nutrient (N, P and S) content responded significantly to combined application of FYM and fertilizer N. Available nutrient content and enzyme activity were higher at vigorous growth stages of crop and gradually declined with maturity of both the crops. In the plots receiving FYM in same season resulted higher accrual in SOC and nutrient content after harvest of the crop, while application in previous season decreased from sowing to harvest. The highest build-up of available K and TOC (1608.5 kg ha-1 and 2.17%, 1598.60 kg ha-1 and 2.21%, respectively for pearl millet and wheat) was recorded in the plots receiving FYM in both the seasons. In pearl millet-wheat cropping, after harvest of both the crops C-fractions followed the order as: less labile>very labile>recalcitrant>labile. After pearl and wheat millet harvest, with the application of FYM in rabi, kharif and both seasons, less labile+recalcitrant fraction was about 56.7, 56.0 and 54.5%, 54.1, 56.7 and 51.4% of TOC, respectively. The MBC, MBN and MBP content increased with increasing FYM application rate and addition of fertilizer N and discernible increase was noticed with application of 15 Mg FYM ha-1 yr-1. Continuous application of FYM for 51 years significantly increased the soluble salts in all the treatment which was reflected in higher EC of soil and seeds. The total N, P, K and S content in soil after wheat harvest was varied from 852.0 to 2739.3; 685.7 to 1644.4; 20424.7 to 29038.9 and 353.3 to 2654.4 kg ha-1, respectively among different treatments. Among different modes of FYM application, total nutrients content in soil followed the order: both season>rabi>kharif. The highest grain yield (20.6 and 55.6 q ha-1 for pearl millet and wheat, respectively) was obtained with the application of 10 Mg ha-1 yr-1 in combination with 120 kg N ha-1 yr-1. The results showed that N, P and K content in pearl millet grain and wheat ranged from 1.75 to 2.12; 0.123 to 0.239 and 0.317 to 0.423 %, 1.66 to 2.09; 0.38 to 0.53 and 0.39 to 0.59 %, respectively. Comparatively higher nutrient content was recorded with combined application of FYM and fertilizer N as compared to applied alone. All the seed quality parameters (EC, protein content, standard germination, Tz test, seedling length and dry weight, vigour index) except test weight of seeds were found improved with increasing application rate of FYM in both the crops. The integrated use of organic manures and fertilizers resulted in higher productivity, improved soil health and maintained the sustainability of pearl millet-wheat crop rotation. | en_US |
