dc.description.abstractThe present investigation on “Physiological investigation for productivity in black gram (Vigna mungo L.) under different environments” was conducted at Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand campus - 388 110, Gujarat during the season kharif 2014, 2015 and summer 2015, 2016. The field experiments were laid out in Factorial Randomized Block (FRBD) design with three replications consisting of two dates of sowing viz., S1- 15th July and S2-30th July during kharif season and S1 -15th and Feb., S2-1st March during summer season respectively with eight varieties viz., TAU-1, GU-1, VUG-10, VUG-11, VUG-14, LBG-645, LBG-709 and Anta landrace for the evaluation of various morpho-physiological, growth, biophysical, biochemical, yield and yield attributing parameters. Black gram varieties differed significantly in which varieties Anta landrace followed by GU-1 during kharif seasons while, variety GU-1 during summer seasons recorded higher values for morpho-physiological parameters __________________________________________________________________Abstract ii (number of branches and nodes plant-1, leaf, stem, root, pod and total dry matter), growth parameters (Leaf area (LA), leaf area index (LAI), Specific Leaf Weight (SLW), Leaf Area Ratio (LAR), Leaf Area Duration (LAD), Net Assimilation Rate (NAR), Crop Growth Rate (CGR), Absolute Growth Rate (AGR), Relative Growth Rate (RGR) and Biomass Duration (BMD), biophysical parameters viz., photosynthetic rate (Pn), photosynthetic active radiation (PAR), difference in CO2 input and output and transpiration rate (E), biochemical parameters (chlorophyll content), yield and yield attributing parameters (number of pods plant-1, length of pod, number of seeds pod-1, 1000 seed weight, seed yield plant- 1, seed yield hectare-1 and harvest index) followed by variety GU-1 during kharif seasons. In case of date of sowing, the values of various morpho-physiological (number of branches and nodes plant-1, leaf, stem, root, pod and total dry matter), growth parameters (Leaf area (LA), leaf area index (LAI), Specific Leaf Weight (SLW), Leaf Area Ratio (LAR), Leaf Area Duration (LAD), Net Assimilation Rate (NAR), Crop Growth Rate (CGR), Absolute Growth Rate (AGR), Relative Growth Rate (RGR) and Biomass Duration (BMD), biophysical parameters viz., photosynthetic rate (Pn), photosynthetic active radiation (PAR), difference in CO2 input and output and transpiration rate (E), biochemical parameters (chlorophyll content), yield and yield attributing parameters (number of pods plant-1, length of pod, number of seeds pod-1, 1000 seed weight, seed yield plant- 1, seed yield hectare-1 and harvest index) of black gram were significantly higher with 15th July sowing during kharif season and 1st March during summer season __________________________________________________________________Abstract iii than 30th July during kharif season and 15th Feb. during summer season sown crop, respectively. The interaction between varieties and date of sowing were found nonsignificant for morpho-physiological, growth, biophysical and biochemical parameters as well as yield and yield attributing characters. This indicates that performance of these varieties was not influenced by dates of sowing. From the above results it can be concluded that the varieties Anta landrace and GU-1 in kharif season while GU-1 in summer season were physiologically more efficient and thereby resulted in higher yield, respectively. The study also indicated that black gram crop if sown on 15th July during kharif season and 1st March during summer season can drive sustainable higher yield production.en_US
