Abstract

Mulch can effectively minimize water vapour loss, soil erosion, weed problems and nutrient loss. Modification of soil microclimate by mulching favours seedling emergence and root proliferation. Organic mulches add nutrients to the soil when decomposed by microbes in the soil. A field experiment was conducted during the rabi season of 2018 and the treatments comprised of one control (T1 -no mulch) and six levels of rice husk mulching viz, T2 (10q/ha), T3 (20q/ha), T4 (30q/ha), T5 (40q/ha), T6 (50q/ha)and T7 (60q/ ha) were laid out in RBD with three replications. The application of rice husk mulching 60q/ha (T7 ) had significant effect on the germination percentage of the crop. The highest number of pods, pods per plant and longest pod length were recorded in the treatment of rice husk mulching with 60q/ha (T7 ). The test weight was found to be non-significant. With respect to economics of yield production in pea, higher gross returns, net returns and returns per rupee invested (B:C ratio) was obtained by 60q/ha rice husk mulching as compared to the other treatments. From the present investigation it was observed that pea was found to perform better in rice husk mulching of 60q/ha.

稻壳覆盖对豌豆发芽率、产量及经济效益的影响。

覆盖物可以有效地减少水蒸气损失、土壤侵蚀、杂草问题和养分损失。覆盖对土壤小气候的改变有利于幼苗出苗和根系增殖。有机地膜被土壤中的微生物分解后，为土壤增加养分。在2018年rabi季进行田间试验，在RBD中设置1个对照(T1不覆盖)和6个稻壳覆盖处理，即T2 (10q/ha)、T3 (20q/ha)、T4 (30q/ha)、T5 (40q/ha)、T6 (50q/ha)和T7 (60q/ ha)，共3个重复。施谷壳覆盖60q/ha (T7)对作物发芽率有显著影响。稻壳覆盖用量为60q/ hm2 (T7)时，单株荚果数、荚果数和荚果长最高。试验重量发现不显著。就豌豆产量生产的经济性而言，与其他处理相比，覆盖60季/公顷稻壳可获得更高的总回报、净回报和每卢比投资回报(B:C比率)。本研究发现，在60q/ha的稻壳覆盖条件下，豌豆表现较好。
