The present study was conducted at Crop Research Centre (CRC), School of Agriculture, ITM University, Gwalior (MP) to investigate the effect of integrated nutrient management (INM) on growth, yield and quality of mustard (Brassica juncea L.). The experiment was laid out in the randomized block design with three replications and each replication was comprised of eleven treatment combinations comprising FYM (Farm Yard Manure) and Azotobacter with recommended dose of N, P, K and S (80: 60: 30: 30). These treatments were investigated for different morphophysiological, yield and quality attributes of miaze crop. Significant improvement in different morpho-physiological attributes viz., plant height, number of branches per plant and dry matter at 30, 60 and 90 days after sowing (DAS), was recorded with T5 treatment. The seed yield was recorded highest (11.33 q/ha) with T5 treatment (100% RDF + FYM @ 15 t/ha + Azotobacter @ 5kg/ha). Maximum harvest index (25.54 %) was also calculated highest for T5 treatment followed by T3 treatment (18.77%) (100% RDF + FYM @ 15 t/ha). Comparatively, the improvement in protein (34.67%) and oil content (39.30%) in mustard cake was maximum for T5 treatment to other treatments. The results of the study revealed that T5 treatment had the maximum significant effect on yield and quality of the mustard crop.
The Indian gooseberry is a monoecious tree and bears a unisexual flower where a high degree of cross-pollination is required for an ideal fruit set as well as better productivity. The fruit set, retention and yield in gooseberry depends on the nutritional and hormonal balance of the tree. The current work is based on the objective to estimate the fruit set, retention, sex ratio and yield in gooseberry after application of a recommended dose of fertilization (RDF) in association with farm yard manure (FYM) and biofertilizers (Azotobacter, Azospirillum and phosphate solubilizing bacteria). The maximum sex ratio was estimated in control (250.22 and 251.09) due to sufficient nitrogen fertilization. However, the highest fruit set, retention percent and yield per tree were reported with the treatment containing three-fourth of RDF in combination with Azotobacter, Azospirillum and PSB (phosphate solubilizing bacteria). Further, it was observed that about 25 to 50% replacement in RDF could be possible through biofertilizer application as a constant source of nutrients to trees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
