ABSTRACT: A field study to evaluate the “Response of various sesame (Sesamum indicum L.) varieties under the influence of nitrogen and phosphorus doses’’ was
carried out at Oilseeds Section, Agriculture Research Institute, Tandojam
during Kharif 2013. The experiment was laid out in a three replicated
randomized complete block design (RCBD) factorial, having net plot size 6 × 3 m
(18 m2). The treatments comprised two varieties such as S-17 and
Pr-125, and six doses of NP i.e. (No fertilizer
(Control), NP @ 30 - 30 kg·ha-1, NP @ 50 - 30 kg·ha-1, NP
@ 50 - 50 kg·ha-1, NP @ 70 - 50 kg·ha-1 and NP @ 70 - 70 kg·ha-1). The analysis of variance suggested that all the doses
of NP affected significantly (P In the case of fertilizer doses, NP @ 70 - 70 kg·ha-1 produced
maximum plant height (102.33 cm), branches plant-1 (18.50), capsules
plant-1 (42.17), seeds capsule-1 (57.67), seed weight
plant-1 (37.50 g), seed index (3.10 g) and seed yield (774.17 kg·ha-1),
whereas NP @ 70 + 50 kg·ha-1 and NP @ 50 - 50 kg·ha-1 ranked 2nd and 3rd in all the growth and yield traits, particularly seed yield
(763.50 kg·ha-1 and 694.50 kg·ha-1). Among sesame
varieties, S-17 resulted in maximum plant height (91.89 cm), branches plant-1 (15.11), capsules plant-1 (37.06), seeds capsule-1 (50.56), seed weight plant-1 (32.00 g), seed index (2.63 g) and seed
yield (682.11 kg·ha-1), whereas variety Pr-125 resulted in minimum
traits, particularly seed yield (657.56 kg·ha-1). In the case of interactive
effects, the interaction of NP @ 70 - 70 kg·ha-1 × variety S-17 produced maximum values, particularly seed yield (782.67), whereas
minimum results were recorded in the interaction of No fertilizer (Control) × variety
Pr-125. Hence results concluded that the interaction of NP @ 70 - 50 kg·ha-1 variety S-17 was found most economical for obtaining optimum yield of
sesame because of non-significant differences with NP @ 70 - 70 kg·ha-1.
