Abstract

To evaluate the growth duration and seed yield of two different Guar ecotypes in response to planting time and plant density, a field experiment was conducted in 2016 growing season at the research field of Tarbiat Modares University, Iran. Experimantal factors were arranged as split plot-factorial in a randomized complete block design with three replications. The experimental factors included four planting dates (21 May, 4 June, 21 June and 5 July) assigned to main plots, and factorial combination of three plant densities (130, 200 and 400 thousand plants. ha-1) and two Guar ecotypes (Pakistani and Indian) as sub-plots. The results showed that maximum seed yield (3004. 8 kg. ha-1) was obtained from 21 May sowing date and plant density of 130 thousand plants ha-1, while in 4 June sowing date, the highest seed yield was harvested from plant density of 200 thousand plants. ha-1 (1834. 4 kg. ha-1). There was significant difference for grain yiled between ecotypes in 21 May and 5 June sowing dates. Pakistani ecotype produced highest highest seed yield (2706. 1 kg. ha-1) in 21 May sowing date. In the second sowing date (4 June), the Pakistani ecotype produced 32. 1% grain yield more than the Indian ecotype. Pakistani ecotype was superior for seed endosperm percentage (40. 5%) as compared to the Indian ecotype (38. 8%). In conclusion, sowing of Pakistani ecotype on 21 May with plant density of 130 thousand plants. ha-1 had higher seed yield, longer growing duration, taller plant height, higher 1000-seed weight, higher pod number per square meter, dry matter and harvest index. Therefore, it could be suitable for climatic conditions similar to Karaj in Iran.
