Abstract

The present investigation entitled “Effect of NPK and biofertilizers on growth and yield of chilli (Capsicum annuum L.)” was carried out at the Research Area, ITM University, Gwalior (M.P.) Chilli (Capsicum annuum L.) belongs to family Solanaceae and it is originated in Tropical America. A large number of constraints limit the production of chilli which includes low yielding ability of genetic material, imbalanced supply of nutrients and pest and diseases. Biofertilizers are inputs containing microorganisms which are capable of mobilizing nutritive elements from non-usable form to usable form through biological process. These natural fertilizers help to enhance productivity by biological nitrogen fixation or solubilization of insoluble phosphate or producing hormones, vitamins and other growth factors required for plant growth. The experiment was laid out in the Randomized Block Design with three replications. Each replication was comprised of seven treatments (viz., T1 – Control (100 % RDF), T2 – 100 % RDF + FYM + PSB, T3 – 75 % RDF + FYM + PSB, T4 – 100 % RDF + FYM + Azotobacter, T5 – 75 % RDF + FYM + Azotobacter, T6 – 100 % RDF + FYM + PSB + Azotobacter and T7 – 75 % RDF + FYM + PSB + Azotobacter) were applied in chilli. Result reported that the FYM and biofertilizers with different dose of NPK were significantly influenced the all the growth parameters viz plant height (cm), number of branches per plant, days to first flowering and days to 50 % flowering and yield parameters viz number of fruits per plant, fruit length (cm), fruit diameter(mm), number of fruits per plant, number of seed per fruit, average fruit weight (g), fruit yield per plant (g), fruit yield per plot (kg) fruit yield per hectare (q) etc. Among all the treatment T6 (100 % RDF + FYM + PSB + Azotobacter) was found the best treatment and it gave the maximum growth parameters yield parameters of chilli whereas the minimum growth parameters and yield parameters were recorded in treatment T1 (Control -100 % RDF). The maximum cost of cultivation, gross returns, net returns and B:C ratio was recorded in treatment T6 (100 % RDF + FYM + PSB + Azotobacter), 47 whereas the minimum cost of cultivation, gross returns, net returns and B:C ratio was observed in treatment T1 (Control -100 % RDF).

Conclusion

It can be concluded from the result that the FYM and biofertilizers with different dose of NPK were significantly influenced the growth and yield of chilli and the treatment T6 (100 % RDF + FYM + PSB + Azotobacter) was found the best treatment among all the treatments and it gave the maximum growth, yield and economic parameters, whereas the minimum growth, yield and economic parameters were recorded in treatment T1 (Control-100 % RDF). On the basis of the result obtained after completion of present investigation we can also say that using integrated farming system not only increase the production but reduce the consumption of chemical fertilizer and may also improve the soil health. But the further research work is needed to confirm the findings of the present investigation.
