Chlorophyll and Nutrient Content in Black gram using Organic Manures under Drought Stress
ثبت نشده
چکیده
This study was conducted to evaluate the performance of black gram (Vigna mungo.L) grown under drought stress using coir waste manure and cow dung manure. Two varieties of black gram-ATD mash 3 and ATD mash 1 were the treatment variables. A best fit positive relationship existed between leaf chlorophyll and leaf nitrogen content with two organic manures. N, P and K accumulation in the two varieties was affected significantly. However there was increasing tendency of N, P and K levels using coir waste manure. This is due to water holding capacity and drought resistance activity of coir waste. Among the two varieties ATD mash 3 showed better performances than ATD mash1.

In this study the effects of drought stress on proline, protein, chlorophyll a/b, ascorbate and dehrydroascorbate were investigated in Akri and Mobil cultivars of tomato species. The seeds were cultured at 23 °C with 15-16 hours light period and irrigation was done based on field capacity control (FC), mild drought stress (⅔ FC) and severe drought stress (⅓ FC) under greenhouse conditions. Afte...
