Effect of foliar application of micronutrients in tomato (Lycopersicon esculentum Mill.) cv. GUJARAT TOMATO-2

Abstract

The present investigation was undertaken with the main objective to study the effect of foliar application of micronutrients in tomato (Lycopersicon esculentum Mill.) cv. GUJARAT TOMATO-2 at ASPEE, ARDF, Tansa farm during Rabi season 2012-2013. The experiment consisted of eight treatments viz., T 1 [RD NPK through chemical fertilizers N: P 2 O 5 : K 2 O 5 kg ha-1 (75 : 37.5 : 62.5)], T 2 (T 1 + 100 ppm B; i.e. boric acid 0.571 g l-1), T 3 (T 1 +100 ppm Zn; i.e. zinc sulphate 0.246 g l-1), T 4 (T 1 + 100 ppm Cu; i.e. copper sulphate 0.420 g l-1), T 5 (T 1 +100 ppm Fe; i.e. ferrous sulphate 0.515 g l-1), T 6 (T 1 +100 ppm Mn; i.e. manganese sulphate 0.320 g l-1), and T 7 (T 1 + mixture of all micronutrients) and T 8 (T 1 + multiplex 4 ml l-1) by mixing with simple water were imposed. The foliar application was made by using equipment knapsack sprayer in the evening hours. The thrice times foliar spray were made at 10 days interval starting from 40 days after transplanting seedling. The data clearly showed that the yield obtained with treatment T 7 had significantly maximum plant height (131.73 cm), number of branches plant-1 (5.81), fresh weight of plants (25.65 t ha-1), dry matter yield of plants (7670.03 kg ha-1), maximum days to last picking (166.68), number of fruits plant-1 (34.26), fruit length (5.52 cm), fruit diameter (4.64 cm), fruit volume (67.53 cm 3), single fruit weight (49.20 g), fruit weight plant-1 (1.68 kg), number of locules fruit-1 (3.03), pericarp thickness (6.23 mm), fruit yield ha-1 (46.78 t) and marketable fruit yield ha-1 (45.62 t). This treatment had maximum net return (1, 66,757 Rs./ ha) and B:C Ratio 2.72 : 1 out all other treatments than over control.

Effect of Micronutrients and Bioinoculants on Physiological and Yield Parameters of Chilli (Capsium Annuum L.)

“…These findings align with the results reported by Barche et al (2011), Patil et al (2013, Saravaiya et al (2014) and Ali et al (2013).…”

Effect of Organic and Inorganic Fertilizers on the Growth and Yield of Tomato (Solanum Lycopersicum) under Protected Cultivation

“…There was significant difference among the doses of the different treatments, among the treatment applied the maximum fruit yield per plant of tomato was recorded in T 6 (25% RDF + 75% FYM) with (8.63 kg) which was followed by T 7 (75% RDF + 25% Poultry manure) with (8.03 kg) which was significantly superior over T 0 (100% Recommended dose of fertilizer) with (4.65) kg. These results are in close conformity with the findings of Sivaiah et al [19]; Ali et al [20]; Haleema et al [21]; Satyamurthy et al [17]; Pandiyan et al [22]; Singh et al [16] and Shnain et al (2021) as reported in tomato.…”

Foliar Nutrition with Water Soluble Macro and Micro Nutrient Fertilizers for Yield Maximization in Bush Vegetable Cowpea

“…Singhal et al (2015) reported that foliar feeding of water-soluble nutrients significantly improved the okra yield and recorded higher net income. Saravaiya et al (2014) observed an increase in net income and B:C ratio due to foliar application of B 100 mg L -1 in tomato. The control treatment (T 1 ) registered the lowest net return and B:C ratio due to lesser pod yield recorded in the treatment.…”

“…An enhancement in number of flowers per plant, number of pods per plant, pod length and pod weight were noticed in cowpea due to application of 125 per cent RDF along with 2 per cent DAP spray at flowering and pod formation stages (Kavitha et al, 2019). Foliar nutrition of Zn (100 mg L -1 ) and B (100 mg L -1 ) recorded significantly higher fruit length and number of fruits per plant in tomato receiving (Saravaiya et al, 2014). Foliar feeding of Zn (0.05%) in combination with B (0.03%) recorded the highest fruit length, fruit diameter as well as fruit weight in tomato (Sultana et al, 2016).…”
