The effect of irrigation regimes and polymer on some physiological traits of forage Sorghum


Fazeli Rostampour M.
Abstract

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran, but its growth and yield are often constrained by water deficit and poor productivity of sandy soil. Irrigation water is becoming scarcer and more costly. Application of some materials such as Superabsorbent A200 polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The objective of present study was to investigate the effect of irrigation regime and different levels of SAP on dry matter and some physiological traits of sorghum×sudan grass in Zahedan, Iran during 2013. The experimental design was a split-plot with two factors including four irrigation regimes consisting irrigated with 40%, 60%, 80% and 100% crop evapotranspiration (ETc) as main plots and four amounts of SAP (0, 60, 120 and 180 kg ha-1) as subplots in a completely randomized block design with three replications. The results indicated that the effect of irrigation and SAP in all traits were significant (P<0.0001) and also, revealed that the interaction effects of two factors were significant (P<0.01) except leaf area duration and relative water content traits. The results showed that water stress decreased chlorophyll index, leaf area duration, leaf area index, relative water content significantly, while the application of SAP decreased the negative effect of deficit irrigation. According to the results it could be concluded that supplying 80% water requirement the plant and 60 kg ha-1 SAP produced a desirable dry matter.

Keywords: Chlorophyll index, Leaf area duration, Leaf area index, Relative water content.

Entomology and Applied Science Letters is an international peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. Papers on non-insect groups are no longer accepted. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Call for Papers
Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research. This has become the need felt in scientific research due to the emphasis on intra-, inter-, and multi-disciplinary approach.
