Evaluation Of Sweet Sorghum Genotypes For Plant Height, Chlorophyll And Nitrogen Content Under Late Sown Conditions


European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 7, Pages 2684-2690

An experiment was carried out to analyze the effect of sowing dates and genotypic response of sweet sorghum (Sorghum bicolar L.) in relation to plant height, total chlorophyll and nitrogen content in the flag leave at regular intervals i.e. 30, 60, 90 and 120 DAS at the research farm of Lovely Professional University, Punjab. As per the sowing dates is concern, plant height (cm) and amount of chlorophyll (mg g-1 of fresh leaf) and nitrogen content (%) was gradually decreased up to the last sowing dates (D1 to D3). While among the DAS is concern, the amount of chlorophyll content was gradually increased up to 75 DAS and decline thereafter in all the tested genotypes in each dates of sowing. However, the amount of nitrogen (%) was marginally leads by 120 DAS plant as compare to 90 DAS plant. The maximum amount of chlorophyll content was recorded in V1 (SSV 74) followed by V3 (CSV 24 SS) and V2 (SSV 84). While the variety V3 recorded maximum height as well as highest amount of nitrogen content followed by V1 and V2.

Nitrogen, phosphorous and potash are the most restricting nutrient in the soil and are commonly essential plant macro nutrients. They are the commonly additionally added input for production of crops. Three Major Cereals - Rice, Wheat and Maize are utilizing huge amount approximately 90% of total nitrogenous fertilizers used in cereals. Because of growing population and decreasing agricultural land area food security has become a serious global problem. External application of the fertilizers has improved the crop yield during the past 60 years there was adverse effects of this on the environment. Under use of the fertilizers, results in the less crop production simultaneously over use of nitrogenous fertilizers have several soil and environmental consequences. Therefore new solutions are required to increase the yields with reduced fertilization, by increasing the fertilizer use efficiency there by maintaining the Agricultural Sustainability. In this paper we are going to propose some techniques that enhance the fertilizer use efficiency (FUE).
