A field experiment was conducted to find out the response of foliar application of micronutrients on growth, yield and economics of tomato (Lycopersicon esculentum Mill.) at collage orchard, Department of Vegetable Crops, HC & RI, Tamil Nadu Agricultural University, Coimbatore. The treatments consisted of boric acid @100 ppm, ZnSo4 @ 100 ppm, ammonium molybdate @ 50 ppm, copper sulphate @ 100 ppm, ferrous sulphate @ 100 ppm, manganese sulphate @ 100 ppm, mixture of all, mixture of all without B, mixture of all without Zn, mixture of all without Mo, mixture of all without Cu, mixture of all without Fe, mixture of all without Mn, commercial formulation (Multiplex) @ 4 ml/lit and control (without spray). The experiment was laid out in a randomized block design with three replications. All the micronutrients were sprayed individually and in combinations on tomato in three sprays at an interval of 10 days starting from 40 days after transplanting. The results revealed that spraying of mixture of all micronutrients (T7 ) 3 times at an interval of 10 days starting from 40 days after transplanting resulted in the highest plant height (95.7 cm), number of fruits per plant (46.4), fruit weight (61.9 g), fruit yield per plot (63.5 kg), yield/ha (564.1 q) and benefit cost ratio (3.04) followed by the spray of commercial formulation (Multiplex).

A field experiment was carried out at College Orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2014 to 2017 to investigate integrated weed management on growth, yield and economics in okra (Abelmoschus esculentus (L.) Moench) cv. COBhH 1 during kharif seasons. The experiment was laid out in Randomized Block Design (RBD) with seven treatments and replicated three times. The growth and yield attributes viz., plant height, number of fruits per plant, fruit yield per plant, fruit length, fruit girth, fruit yield kg per plot and fruit yield (q/ha) differed significantly due to different treatments. Growth and yield attributes increased significantly in weed free check (T2 ) which led to appropriate timing of weeding which reduced the influence of weed interference and increased the yield in okra. The results revealed that weed free check (T2 ) recorded the higher plant height (151.80 cm), number of fruits/plant (27.30) with an average fruit yield of 0.501 g per plant, fruit length (13.53 cm), fruit girth (7.53 cm), fruit yield (233.9 q/ha) and low weed density (12.03/m2 ) at 60 days after sowing. Whereas, the high cost benefit ratio (2.88) was recorded in pre emergence of pendimethalin @ 1.0 kg/ha + one hand weeding (T4 ) which also recorded 23.36 number of fruits/plant with fruit yield of 223.0 q/ha. It is therefore recommended that pre emergence application of pendimethalin @ 1.0 kg/ha + one hand weeding will be optimal for okra production in kharif season.
