Abstract:
Field experiment was carried out for a couple of years (kharif 2014 to rabi 2016) at Research Farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur to evaluate the role of some nutritional packages (Humic acid and Micronutrients) in the oscillation of major insect and disease pests in rice-mustard cropping system. The, lowest yellow stem borer infestation of rice in the form of mean percent dead heart and white head were encountered in RDF (N80P40K40) + ZnSO4 20 kg ha−1 + Borax 10 kg ha−1 + Humic acid 7.5 l ha−1 followed by RDF (N80P40K40) + Humic acid @7.5 l ha−1 (15 ml plot−1) with compost (10 t ha−1) + Humic acid Foliar Spray one time @ 1 ml litre−1 (7.38% and 10.30%) respectively. Similarly, the same treatment also registered lowest number of brown plant hopper population (5.12 per 3 hills), leaf blast and neck blast T6 (4.63% and 7.31%). Yield potentiality of rice was found to be the highest in same nutritional treatment as compared to control (without humic acid or micronutrient). Similar trend of effectiveness were also encountered in case of mustard where, mean number of aphid population as compared to untreated control plots. Alternaria blight infection was also found very low in case of ZnSO4 20 kg ha−1 + Borax 10 kg ha−1 + Humic acid 7.5 l ha−1 along with RD of NPK. Same nutritional package was also found to be significantly superior in the seed (1.23 t ha−1) yield of mustard.
