The weed population, dry weight of weeds, weed control efficiency and yield components of chilli and coriander were significantly affected in response to weed control treatments. Among the different chemical treatments, pre-emergent application of alachlor @ 1.5 kg ai/ha + 2 HW at 45 and 60 DAT recorded the lowest pooled dry matter of weeds (3.8 g), lowest population of monocot (3.47), dicot weeds (2.82) and thus exhibited the highest weed control efficiency (83.45%). The yield per ha of chilli (285q) and coriander (73.02q) net returns (Rs. 1,33,661) and B:C ratio (2.63) were also found to be highest and it was followed by pre emergence application of pendimethalin at 1.5 kg/ha +2 HW at 45 and 60 DAT.

The experiment was laid out in Completely Randomized Block Design (CRBD) consisting of nine treatments. The treatment comprising of different combinations of nutrients and mulches i.e. Nitrogen (150Kg ha-1 and 200 Kg ha-1), Phosphorous (80 Kg ha-1 and 120 Kg ha-1) and mulches (Paddy straw and water hyacinth each @ 7t ha-1) with three replications. The statistical analysis indicated that the fruit quality of bell pepper was significantly influenced by different nutrients levels and mulches. The biochemical parameters viz. Highest total soluble solids (7.41 0 Bx), chlorophyll content (63.28 SPAD) and Vitamin-C (197.64 mg/100g) were observed in treatment T8 with 200kg N ha-1 + 120kg ha-1 P₂O₅ + Paddy straw mulch @ 7 t ha-1. Control condition indicated significantly lowest result than all other treatment.

The statistical analysis indicated that the fruit yield of bell pepper were significantly influenced by nutrients and mulching. The highest fruit yield per plant (739.31g), fruit yield per plot (12.67 kg) and fruit yield per hectare (21.12 t ha-1) were recorded in treatment T6 with 200kg N ha-1 + 80kg P₂O₅ ha-1 + Paddy straw mulch @ 7 t/ha-1.

The statistical analysis indicated that the fruiting and fruit characteristics of bell pepper were significantly influenced by nutrients and mulching. Highest number of fruits per plant (9.95), highest fruit weight (69.18g), maximum fruit length (9.95cm), diameter (7.37cm) and volume (97.07cm) were observed in the treatment T6 with 200kg N ha + 80kg P2O5 ha + Paddy straw mulch @ 7 t/ha.

The nutrition status of any plants plays a vital role in determining its growth, yield and quality of fruits. An optimal fertilization is contributive in obtaining high yield of good quality and high biological value. Both macro and micronutrients are well known to ameliorate plant growth, yield and quality. Application of nutrients especially macronutrients like nitrogen, phosphorus and potassium etc. is well known to enhance the crop growth and development for optimum yield and to improve quality of produce. It is evident from literature, that nitrogen and phosphorus affect growth, yield and quality of fruits and vegetables. The available literature on effect of nitrogen and phosphorus application on growth parameters, yield components and quality of capsicum and other fruits or vegetable crops are reviewed and presented below.

They are often prolific and persistent, interfere with agricultural operations, increase labour cost and reduce the yield (up to 45 %) and quality. The weed flora noticed in the experimental site consisted of grasses, sedges and broad leaved weed category. The important grassy weeds observed are Cynodon dactylon, Dinebra retroflexa, Eleusine indica, Cyperus rotundus and Setaria italica. C. rotundus was more dominated than other weeds in entire experimental area. In Karnataka, chilli and onion are the most extensively grown commercial vegetable crops under intercropping systems. Chilli+onion intercropping is of the most assured intercropping system and mitigate the weeds to some extent and increases the yield and is found suitable to northern dry zones of Karnataka. This system is widely adopted in Northern Karnataka (Anonymous, 2017).
