Abstract:
An investigation was carried out to standardize the suitable hydrophilic polymer seed coating technique to withstand drought in rainfed Black gram cv. VBN 8. Seven organic hydrophilic polymers namely, Ethyl cellulose, Methyl Cellulose, Carboxyl Methyl Cellulose, Agar Agar, Xanthan Gum, Carrageenan and Gum Arabic were taken and their gel formation and water holding capacities were studied. Among all the polymers Xanthan Gum, Carrageenan, Agar Agar, Carboxy methyl cellulose and Gum Arabic showed higher potential in terms of gel formation and water holding capacity and were used for seed coating studies in three different concentrations (1, 2 and 3%) with two different dosages (20 ml and 40 ml /kg of seeds) and subjected to germination test under 60 % WHC of sand. Results revealed that seeds coated with 2 % carrageenan @ 40 ml /kg of seeds performed better in terms of all seed quality parameters under water stress which was on par with 2% Xanthangum@ 40 ml /kg coated seeds. Further the five identified polymers were tried in combinations. Each polymer were blended with other polymers in the ratio of 1:1 and 3:1 and studied for their stress avoidance potential under 60 % water holding capacity of sand. The results revealed that Blackgram seeds coated with 2 % Agar blended Carrageenan in the ratio of 3:1 @ 40 ml / kg performed better in terms of seed quality parameters and expressed promising effect in drought mitigation.
