Abstract

A field experiment was conducted on influence of secondary nutrients and biofertilizers on postharvest parameters in chilli at College of Horticulture, Mudigere. The major postharvest parameters like physiological loss in weight, rotting percent and shelf life in chilli was studied. Chilli commonly encounter postharvest problems, such as quality degradation, chilling injury when stored below 7 °C, shrivelling associated with rapid loss of weight, begin to turn colour and deteriorate within a few days after harvest in ambient conditions. The lowest physiological loss in weight (1.30 %, 2.17 %, 4.05 % and 6.83 %, respectively) @ 4, 8, 12 and 16 DAS, respectively, rotting percent (1.87 %, 4.34 %, 6.90 % and 11.97 %, respectively) @ 4, 8, 12 and 16 DAS, respectively, maximum days of storage life (16.18 days) were noticed with the application of 75 % RDNPK + CaNO3 @ 0.5 % + MgSO4 @ 0.4 % + Azospirillum + PSB + KSB (T11). Thus, combined use of organic amendments (biofertilizers, FYM) along with chemical fertilizers not only produced highest and sustainable crop yield but also improved the postharvest parameters due to application of calcium and magnesium to chilli.

Keywords

Chilli, secondary nutrients, post-harvest parameters

Conclusion

It can be concluded that combined application of 75 % RDNPK + CaNO3@ 0.5 % + MgSO4@ 0.4 % + Azospirillum + PSB + KSB (T11) showed the significant variation in physiological loss in weight, rotting per cent and also increased the shelf life of chilli fruits.
