摘要

2014 - 2015年秋季，在泰伦加纳邦阿迪拉巴德农业研究站进行了田间试验，评估了秸秆覆盖和抗蒸腾剂对大豆生长和产量的影响。处理包括A)抗蒸腾剂(5)(在开花后15天喷洒):T1 MgCO3 @ 5% T2甘油@ 5% T3 KNO3 @ 1% T4 NaCO3 @ 5% T5控制(水喷洒)B)播种后秸秆覆盖@ 5吨/公顷C)控制(不覆盖)。在不同的抗蒸腾剂中，Na2CO3 @ 5%的平均种子产量较高(2862公斤/公顷)，与甘油@ 5%(2762公斤/公顷)和MgCO3 @ 5%(2731公斤/公顷)相当。覆盖(秸秆覆盖5吨/公顷)显著优于对照(不覆盖)，平均种子产量最高(2723公斤/公顷)。在旱作条件下，秸秆覆盖与防蒸腾剂的组合施用在产量和成本上都是有效的。

Enhancing the Water Stress Tolerance in Soybean (Glycine max L.) through Anti-Transpirants and Mulch

A field experiment was conducted during kharif 2014 2015 in the Agricultural Research Station, Adilabad, Telangana to assess the effect of straw mulch and anti – transpirants on growth and yield of soybean. The treatment consisted of A) Antitranspirants (5) (spray at 15 days after flower initiation): T1 MgCO3 @ 5% T2 Glycerol @ 5% T3 KNO3 @ 1% T4 NaCO3 @ 5% T5 Control (water spray) B). Straw mulch @ 5 t/ ha after sowing C) Control (no mulch). Among the different anti transpirants, Na2CO3 @ 5% recorded higher mean seed yield (2862 kg/ ha) which was at par with Glycerol @ 5% (2762 kg/ ha) and MgCO3 @ 5% (2731 kg/ ha). Mulch (straw mulch @ 5 t/ ha) was significantly superior over control (without mulch) with highest mean seed yield (2723 kg/ ha). The combination of straw mulch and anti – transpirant can be recommended as an effective with respect to yield and cost for the soybean under rainfed condition.
