Potato Crop Growth and Yield Response to Different Levels of Nitrogen under Chhattisgarh Plains Agro-climatic Zone

Biochar (BC) from biomass waste pyrolysis has been widely studied due to its ability to increase carbon (C) sequestration, reduce greenhouse gas (GHG) emissions, and enhance both crop growth and soil quality. This review summarizes the current knowledge of BC production, characterization, and types, with a focus on its positive effects on crop yield and soil properties versus the unintended risks associated with these effects. Biochar-amended soils enhance crop growth and yield via several mechanisms: expanded plant nutrient and water availability through increased use efficiencies, improved soil quality, and suppression of soil and plant diseases. Yield response to BC has been shown to be more evident in acidic and sandy soils than in alkaline and fine-textured soils. Biochar composition and properties vary considerably with feedstock and pyrolysis conditions so much that its concentrations of toxic compounds and heavy metals can negatively impact crop and soil health. Consequently, more small-scale and greenhouse-sited studies are in process to investigate the role of BC/soil/crop types on crop growth, and the mechanisms by which they influence crop yield. Similarly, a need exists for long-term, field-scale studies on the effects (beneficial and harmful) of BC amendment on soil health and crop yields, so that production guidelines and quality standards may be developed for BCs derived from a range of feedstocks.

The experiment was conducted at Horticulture Farm at Sher-e-Bangla Agricultural University, Bangladesh during the period December, 2014 to March 2015 to evaluate the effect of different levels of nitrogen and phosphorous on the growth and yield of bush bean. The two factor experiment was laid out in Randomized Complete Block Design with three replications. The treatment was comprised of two factors- Factor A: levels of nitrogen i) 0 kg/ha, ii) 20 kg/ha, iii) 40 kg/ha and Factor B: levels of phosphorous (P2O5) – i) 0 kg/ha, ii) 50 kg/ha, iii) 75 kg/ha, iv) 100 kg/ha. The results revealed that most of the growth and yield contributing parameters were significantly influenced by the different levels of nitrogen and phosphorous application. The maximum promotive effect on growth and yield of bush bean was associated with 40 kg N/ha and 75 kg P2O5/ha. Again their combined application enhanced maximum vegetative growth and with higher pod yield and seed yield. Therefore, application of 40 kg N/ha with 75 kg P2O5/ha can be conductive for bush bean cultivation in Bangladesh with higher yield.

Aim: To investigate growth and yield response of greengram to different levels of Kolgrace organic fertilizer with a view to determining the most favorable application rate for greengram production. Study Design: Completely randomized design (CRD) with treatments replicated five (5) times. Place and Duration of Study: Screenhouse of the Department of Agronomy, University of Ibadan, Nigeria, between July to November 2016. Methodology: Six levels of kolgrace organic fertilizer were used (0.00, 0.50, 1.00, 2.00, 4.00 and 8.00 t ha-1). Top soil (0 -15 cm) was collected from the Teaching and Research Farm of the Department of Agronomy, and leached of nutrients by soaking and washing in water for 24 hours. 2 kg of air-dry soil was mixed with the appropriate fertilizer rate and filled in each pot. 3 seeds were sown per pot and thinned to 1 seed at 2 weeks after sowing (WAS). Chemical analysis of air-dry soil sample and Kolgrace fertilizer were done at the soil chemistry laboratory of the Department of Agronomy, University of Ibadan, Nigeria, to ascertain their elemental composition. Soil particle size distribution [1], Soil pH [2], exchangeable K and Na [3], exchangeable Mg and Ca [4], exchangeable acidity [5], organic matter and organic carbon [6], available P [7], Nitrogen [8] and micronutrients (Mn, Fe, Cu and Zn) [4] were determined. Results: Application rates were significant (p<0.05) for all the traits measured. 0.5 t ha-1 was significantly higher in plant height (39.5), number of pods (7.0) and dry pod weight (4.98). Application rate of 1 t ha-1 was higher in number of leaves (18.0) although was comparable to application rate of 0.5 t ha-1. Conclusion: Application rate of 0.5 t ha-1 was best for three of the five traits measured and is hereby recommended.

Understanding the crop growth and yield response to variable irrigation and the relationship between crop eco-physiological and morphological parameters is critical for identifying a balanced irrigation management strategy and developing decision support systems for early detection and information for on-ground decisions. Experiments were conducted to evaluate the effect of variable irrigation treatments on dry bean [Phaseolus vulgaris L.] growth traits (plant height, leaf area index, normalized difference vegetation index), seed yield (SY), and yield components (pods plant−1, seeds pod−1, 100-seed weight (SW), and pod harvest index (PHI)) and to develop empirical models between dry bean growth and environmental conditions, SY, and yield components. Five irrigation treatments i.e., FIT (full irrigation treatment), 125% FIT, 75% FIT, 50% FIT, and 25% FIT were investigated. Water deficit at the beginning of the crop growth [vegetative growth (V1-V2) stage], dramatically reduced dry bean growth and development and resulted in a significant reduction in SY. However, the degree to which vegetative growth and SY was reduced depends on the weather conditions. Reducing irrigation by 25% below FIT resulted in an average reduction of 30% in SY. This reduction in SY was significantly correlated with a decline in pods plant−1 and SW. Moreover, the empirical models between growth traits and growing degree days (GDD) have a strong correlation, while growth traits and SY and yield components are moderately correlated. The data and empirical models presented in this research provide valuable information in predicting and estimating dry bean SY in-season and allow for corrective management decisions.

Cropping systems and management practices that improve soil health may greatly enhance crop productivity. Four different potato cropping systems designed to address specific management goals of soil conservation (SC), soil improvement (SI), disease suppression (DS), and a status quo (SQ) standard rotation, along with a non-rotation (PP) control, were evaluated for their effects on potato crop growth, nutrient, and yield characteristics under both irrigated and non-irrigated (rainfed) conditions in field trials in Maine, USA, from 2004 to 2010. Both cropping system and irrigation significantly (p < 0.05) affected most potato crop parameters associated with growth and yield. All rotations increased tuber yield relative to the non-rotation PP control, and the SI system, which included yearly compost amendments, resulted in overall higher yields and a higher percentage of large-size tubers than all other systems with no irrigation (increases of 14 to 90%). DS, which contained disease-suppressive green manures and cover crops, produced the highest yields overall under irrigation (increases of 11 to 35%). Irrigation increased tuber yields in all cropping systems except SI (average increase of 27–37%). SI also resulted in significant increases in leaf area duration and chlorophyll content (as indicators of photosynthetic potential) and root and shoot biomass relative to other cropping systems, particularly under non-irrigated conditions. SI also resulted in higher shoot and tuber tissue concentrations of N, P, and K, but not most micronutrients. Overall, cropping systems that incorporate management practices such as increased rotation length and the use of cover crops, green manures, reduced tillage, and particularly, organic amendments, can substantially improve potato crop growth and yield. Irrigation also substantially increased growth and yield under normal field conditions in Maine, but SI, with its large organic amendments, was essentially a substitute for irrigation, producing comparable results without irrigation.
