Abstract The chapter highlights the potential benefits associated with the use of insect-rearing residues as biofertilizers while exploring the mechanisms by which chitin in insect frass might control common crop pathogens. The potential benefits for soil fertility derived from the use of insect frass, comparison of quality of insect-derived biofertilizers and common organic and inorganic fertilizers and insect frass and plant health improvement are discussed. While more research is essential to understand the true value of insect-derived biofertilizers for plant and soil health, preliminary findings suggest there are significant opportunities for beneficial impacts in agriculture and horticulture to be realized.

Different Doses

The experiment was conducted in research field of Agriculture Research Station at Belachapi, Dhanusha, Nepal from November, 2017 to February, 2018 to evaluate the effects of different doses of organic and inorganic fertilizers on Cauliflower yield parameters and soil properties. In the experiment, there were ten treatments consisting of different combinations of organic and inorganic fertilizers. The cauliflower variety ‘Snow mystic’ was grown with these treatments laid out in a Randomized Complete Block Design with three replications. The half dose of Organic manure (750 kg/ha) and half dose of farm yard manure (FYM) (20 t/ha) produced the highest curd yield (1019 g) and biomass (2046 g). The highest Nitrogen percent (0.10%), Organic matter percent (1.89%) and Phosphorus content (169.09 mg/kg) were obtained with the application of combined half dose of NPK (105:90:60 kg NPK/ha) and half FYM (20 t FYM/ha). The combined effect of application of Organic manures with inorganic fertilizers (NPK) was found to be better for crop growth and development as well as soil health improvement.

Organic And Inorganic Fertilizers

Reliance on inorganic fertilizers with less or no use of organic fertilizers has impaired the productivity of soils worldwide. Therefore, the present study was conducted to quantify the effects of integrated nutrient management on rice yield, nutrient use efficiency, soil fertility, and carbon (C) sequestration in cultivated land. The experiment was designed with seven treatments comprising of a zero input control, recommended inorganic fertilizers (RD), poultry manure (PM) (5 t ha−1) + 50% RD, PM (2.5 t ha−1) + 75% RD, vermicompost (VC) (5 t ha−1) + 50% RD, VC (2.5 t ha−1) + 75% RD, and farmers’ practice (FP) with three replications that were laid out in a randomized complete block design. The highest grain yield (6.16–6.27 t ha−1) was attained when VC and PM were applied at the rate of 2.5 t ha−1 along with 75% RD. Uptake of nutrients and their subsequent use efficiencies appeared higher and satisfactory from the combined application of organic and inorganic fertilizers. The addition of organic fertilizer significantly influenced the organic carbon, total carbon, total nitrogen, ammonium nitrogen, nitrate nitrogen, soil pH, phosphorus, potassium, sulfur, calcium, and magnesium contents in post-harvest soil, which indicated enhancement of soil fertility. The maximum value of the organic carbon stock (18.70 t ha−1), total carbon stock (20.81 t ha−1), and organic carbon sequestration (1.75 t ha−1) was observed in poultry manure at the rate of 5 t ha−1 with 50% RD. The soil bulk density decreased slightly more than that of the control, which indicated the improvement of the physical properties of soil using organic manures. Therefore, regular nourishment of soil with organic and inorganic fertilizers might help rejuvenate the soils and ensure agricultural sustainability.
