Soil fertility management plays a key role in sustaining different production systems. Present investigation aimed at determining available nutrient status in cultivated soils under maize-wheat and paddy-wheat cropping sequences in outer Himalayas of Himachal Pradesh. Based on the standard GPS based soil sampling methodology, composite surface soil samples (0-15 cm) from 38 and 15 representative sites were collected from soils under maize-wheat and paddy-wheat cropping sequences, respectively. Six to eight cores of surface soils were collected from croplands to make one composite sample in 2016 & 2017. Out of 38 (maize-wheat) sites, 24 and 14 sites represent the cultivated Entisols and Inceptisols. Similarly, under paddy-wheat, 8 and 7 sites represent Entisols and Inceptisols. The results of the investigation revealed that soils were medium in available N & K, low in available P & S, high in available Ca & Mg, sufficient in available Cu, Fe & Mn and deficient to sufficient in available Zn and B. Inceptisols had higher value of all the nutrients as compared to Entisols. The available nutrient status viz., N, P, S, Zn and B were deficient to the extent of 26, 42, 57, 40 and 42 per cent, respectively. The overall evaluation of the study area revealed very high variation on the fertility status.

A field experiment was conducted in the central farm, Regional Research and Technology Transfer Station, Coastal Zone OUAT, Bhubaneswar, Odisha, India during kharif 2020 using cv-Lalat variety of Rice. The experiment was laid out in randomized block design (RBD) with ten treatments and three replications. In this experiment BOF (Basic Oxygen Furnace) slag was used as a source of silica for application to rice crop. 200, 300 and 400 kg SiO2/ha was applied in combination with 50% STD (Soil Test Dose) and 75% STD to assess the efficacy of Silica with reduction in fertilizer dose by 50% and 25%. It was shown that increase in number of effective tillers (7.8) per plant and length of the panicle (25.8 cm), but no significant increase was marked in case of 1000 grain weight (gm.) over control. In case of grain yield, straw yield and harvest index, 100% STD (T4) registered maximum (36.9q/ha) grain yield which was 29.4% more than that of control. Of course, grain yield in case of T9 i.e., 75% STD+300 kg SiO2/ha was at par 36.2q/ha indicated efficacy of silica application by reducing fertilizer dose. Harvest index was not affected by Si treatments. However, maximum HI (0.478) was observed in T9. Available N, P, K and S status in post-harvest soil was increased due to application of silica along with fertilizer over control indicated better availability of nutrients which plays a vital role in increasing production and productivity of rice. The study revealed that the DTPA extractable Fe and Mn content decreased, and Cu and Zn content increased with increased application of silica. Though 100% STD (T4) was found to be very effective as compared to other treatments but 75% STD + 300kgSiO2/ha was also equally effective so far as yield, growth attributing characters, available nutrient status of paddy.

Background: The uncertainty of groundnut productivity in the rainfed areas could be minimized by in situ conserving the soil moisture received through precipitation during the cropping period and improving the nutrient status. Methods: A field experiment was conducted at the Department of Agronomy, Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, Tamil Nadu during 2014-2015 rabi season to find out the effect of charred rice husk and other organic materials enriched with or without fertilizer nutrient on the moisture retention and nutrient supply during the deficit period of crop growth. The treatment consists of charred rice husk, biochar, lignite and farm yard manure alone and enriched with the recommended dose of nitrogen (10 kg ha-1) and phosphorus (10 kg ha-1) fertilizer and compared with the absolute control and recommended dose of fertilizer (10:10:45 kg NPK ha-1). Result: The structural morphology of organic materials was studied using Scanning Electron Microscope (SEM) showed that the particles of charred rice husk were uneven and the diameter varied from 3-4 ìm with clod and block appearance, the particles of biochar were irregular in shape, uneven sized and diameter varied from 2-3 ìm with block appearance and the lignite particles found spherical and aggregated. The chemical composition of organic manure with nutrient examined under SEM-EDAX revealed that the charred rice husk contains 64.31% carbon, 28.42% oxygen and 5.96% silica. Results of the study revealed that, application of enriched FYM at 5 t ha-1 recorded significantly higher pod yield (2190 kg ha-1). The enriched biochar and charred rice husk produced comparable pod yield of 2010 kg ha-1 and 1983 kg ha-1, respectively.
