Abstract

The present investigation on response of organic nutrient management on the yield attributes, yield and economics of sesame and potato crop in sesame - potato sequence in Gwalior regions was conducted at ICAR, Central Potato Research Institute – RS, Gwalior (M.P.) during two consecutive years (2020-21 and 2021-22). The experiment was laid out in Randomized Block Design (RBD) with four replications having 7 treatments. The treatments comprised of decomposed crop residue @ 25 t ha-1 with biofertilizer (Azotobacter and PSB), FYM @ 25 t ha-1, vermicompost @ 7.5 t ha-1, neem cake @ 5 t ha-1 in different treatments in addition to control, 100% RDF and INM (100% RDF + FYM @ 25 t ha-1). The results revealed that among all the organic manures, RDF and integrated treatment T7 (100% RDF + FYM 25 t ha-1) showed better results in phenological parameters like days to flower initiation (50.3 and 51.6), days to 50% flowering (55.9 only 2021-22), days to capsule initiation (64.4 and 65.5) and days to 50% capsule formation which were numerically higher with 100% RDF NPK during 2020-21 and T3 + vermicompost @ 7.5 t ha-1 (71.4) during 2021-22 as compared to other treatments. Yield and yield attributing characters were noted significantly higher under 100% RDF + FYM @ 25 t ha-1 viz., number of capsules plant-1 (92.4 and 83.5, respectively), seeds capsule-1 (72.4 in 2020-21) but capsule length was showed non significant effect under different treatments. Seed (944 and 870 kg ha-1) and stover yields (3013 and 2980 kg ha-1) in sesame were recorded highest under 100 % RDF + FYM @ 25 t ha-1 crop during 2020-21 and 2021-22, respectively. Application of 100% RDF + FYM @25 t ha-1 gave significantly higher yield attributing characters viz. number of tubers plant-1 (12.13 and 10.45), fresh weight of tuber plant-1 (522.9 and 508.2 g) and dry weight of tuber plant-1 (103.2 and 97.4 g) which were significantly superior over other treatments. Tuber yield (44.2 and 47.2 t ha-1) of potato during 2020-21 and 2021-22 were also highest under 100% RDF + FYM @ 25 t ha-1. Highest harvest index was recorded with T3 + neem cake @ 5 t ha-1 (84.5%) which was significantly higher than 100% RDF NPK and 100% RDF + FYM @ 25 t ha-1 during 2020-21. However, it was highest with T3 + FYM @ 25 t ha-1 during 2021-22 which was significantly higher than 100% RDF + FYM @ 25 t ha-1. Application of crop residue @ 25 t ha-1 + Biofertilizer (Azotobacter + PSB, @ 1 l ha-1, each respectively) produced the highest net returns (` 53144 and 44360 ha-1) in sesame crop during first and second years, respectively. Application of T3 + FYM @ 25 t ha-1 obtained the highest net returns (` 438334 and 402240 ha-1) in potato crop during first and second years, respectively. Thus, organic production of sesame and potato under sesame - potato sequence may be taken as economically viable options.

Conclusion

It may be concluded that application of 100% RDF + FYM @ 25 t ha-1 was noted superior phenological, yield attributes and yield resulting in higher remuneration for sesame and potato crops in sesame - potato sequence.
