A field experiment was conducted to evaluate the effect of different Nitrogen levels on the yield performance of four rice hybrid in two consecutive Monsoon Season of 2020 and 2021. The experiment was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj Ayodhya (U.P.). The experiment was conducted in factorial randomized block design with three replication which comprised of 4 levels of nitrogen viz. 0% RDN, 50% RDN, 75% RDN and 100% RDN and 4 hybrid varieties viz. Arize-6444 Gold, Ankur-7576, 27P31 and Shahi-Dawat. Results revealed that significantly higher yield contributing characters and yield was obtained  at 100% of RDN (150 kg N ha-1) which is at par with 75 % RDN (112 kg N ha-1) and significantly superior over 0% of RDN and 50% of RDN (75kg N ha-1). The growth parameters, yield attributes and yield were recorded significantly higher with Ankur-7576 variety except length of panicle (cm) and test weight (g). Ankur-7576 gave good response in low doses of nitrogenous fertilizer and showed good efficiency in utilization of available and applied nitrogen to the crop and best suitable for obtaining higher yield of hybrid rice.

The study which was aimed at detecting the effects of the properties of Taraxacum officinale on the characteristics of the soils was carried out in a garden in Use Offot Community in Uyo, Akwa Ibom state using the purposive sampling method. The samples were collected at a depth of 0-30 cm from different points in the study area, and were bulked into one composite sample. Standard procedures were adopted in the analyses of the soil sample and the results of the analysis of the sample showed that the soil with Taraxacum officinale had a neutral soil pH (7.055) as against the control soil which had a slightly acidic pH (6.72). The organic carbon, total nitrogen and available phosphorus contents were 0.78 %, 0.04 %, and 87.04 mg/kg respectively.  The average cation exchange capacity (3.25 cmol/kg) was low; also the soil texture of the samples were identified as loamy sand. These values revealed that Taraxacum officinale had effects on the physicochemical properties of the soil it grew on.

This study evaluates the fertilizing potential of micaschist powder in sugarcane farming on ferrallitic soils of the Mbandjok area in Cameroon. These soils are poor in exchangeable cations and assimil able phosphorus, very acidic, with low to moderate CEC. An experimental design, which consisted in a randomized Fischer block, is composed of six replications of five treatments:T0: conventional fertilization (Ureemulticote 39 00, 150 kg ha-1; MAP, 125kg ha-1; KCl,250kg ha-1) T0-M1: T0 + 5 t ha-1of Micaschist powder, T0-M2: T0 + 7 t ha-1of Micaschist powder, NP-M1:N and P supply, conventional dose (no KCl) + 5 t ha-1of Micaschist powder, N-M2: N supply, conventional dose (no P and K) + 7 t ha-1of Micaschist powder. The experiment was carried out between October 2015 and February 2019. During this period, soil samples were collected, sugarcane was planted and monitored with great care in order to determine the parameters indicative of the growth and yield of sugarcane plants. The results indicate an important increase of the sugarcane yield during the three years of experiment, on soils where micaschist powder was added, compared to the control. Concerning the percentage of lift and voids, the T0-M1 treatment had 3% of voids compared to the T0 (9%) treatment which is the reference fertilizer; for Tillers parameter, T0-M1 (338 stems) performs very well during the experiment compared to the T0 (297stems) and for the growth parameter, T0-M1 treatment was good increasing from 182 cm in the first year to 280 cm in the second year. This suggests that micaschist powder has a positive and significant effect on the growth components. For the yield of sugarcane, the best result of tons of sugarcane (TC) was obtained with T0-M1 treatment which increased from 77.15 TC ha-1 in the first year to 86.13TC ha-1 in the third year. The overall results indicate that using micaschist powder as fertilizer can enhance sugar cane yield with a long lasting residual effect of rock powder.

Soil characterization and classification are prerequisites for better agricultural productivity and sustainable soil fertility management. This study was previously conducted to characterize and classify DelboAtwaro, a watershed in southern Ethiopia. Three pedons classes were inspected and three representative pits (pedons) opened, i.e. one in each pedon. Pedons were described in accordance with FAO [1] and WRB (2014) in the study area, and then soil samples were collected from recognized horizons of each pedon and analyzed for selected physicochemical properties. The pedons confirmed the variability of the physical, chemical and morphological properties of the soils in the study area. Based on the result of field and laboratory soil analysis, the soil structure was early clay in both aboveground and subterranean strata. The soil chemical reaction used to be somewhat acidic to neutral in reaction (pH 6.1-7.0). The organic carbon (OC) content varied between 1.23 and 1.78% between the respective topographical positions. The cationexchange capacity (CEC) of the soils ranged from 39.8 to 79.9 cmol (+) kg-1 (intermediate to optimal), while the percent base saturation (PBS) ranged from 23.7 to 40.7%. The dominance of the exchangeable bases was once, in descending order, Ca>Mg>K>Na. Soils ranged from low to optimal in TN and very low to low in available P, while the concentrations of micronutrients in the soils were best (Fe), very high (Mn), adequate (Zn), and optimum (Cu). The soil had a molly epipedon with humic diagnostic houses in the subsurface. Hence the soil was categorized as Rhodic Nitisols (Haplic) (US, MS, and LS) according to the WRB for soil resources. In general, slope and land use influenced soil properties in the different topographical locations of the Delbo Atwaro Underwater Catchment, suggesting the need for integrated soil fertility management to sustainably conserve soil organic matter and nutrients.
