Effect of organic manures, biofertilizers and micronutrients on growth, yield and quality of onion (Allium cepa L.)

A field experiment was conducted during the Rabi season to find out the effect of organic manures, biofertilizers and micronutrients on growth, yield and quality of onion cv. NHRDF Red - 2. There were 13 treatments viz. , T 0 (Recommended dose of fertilizers), T 1 Poultry manure, T 2 vermicompost, T 3 Azotobacter , T 4 VAM, T 5 Azotobacter +RDF (50%)+zinc, T 6 Azotobacter +RDF(75%)+zinc, T 7 VAM+RDF(50%)+boron, T 8 VAM+RDF (75%)+boron, T 9 RDF (25%)+VAM+poultry manure (50%)+ Azotobacter +boron, T 10 (RDF (25%)+VAM+vermicompost (50%)+ Azotobacter +boron, T 11 RDF (25%)+VAM+poultry manure (50%) Azotobacter +zinc, T 12 RDF (25%)+VAM+vermicompost 50% Azotobacter +zinc and the experiment was laid out under RBD with three replications. The study clearly revealed that there were significant effects of various treatments on the growth, yield and quality attributes of onion. The number of leaves per plant (12.15), plant height (73.02cm), neck thickness (22.00mm), bulb length (6.46 cm), bulb diameter (7.20cm), yield (398.36 kg/ha -1 ) were recorded maximum in treatment T 12 whereas T.S.S (14 °B), vitamin C (12.11mg/100g), total sugars (10.52%), reducing sugar (6.23%) and non-reducing sugar (4.28%) were found maximum in T 10 treatment as compared to other treatment. However, T 12 was good for higher yield improvement and T 10 was the best for quality improvement among the all treatments under study, the application of T 12 (RDF (25%)+VAM+Vermicompost 50% Azotobacter +Zinc) may be suggested for successful cultivation of onion in Lucknow.

Improvement of growth, yield and quality of tomato (Solanum lycopersicum L.) cv. Azad T-6 with foliar application of zinc and boron

The present investigation was conducted to find out the response of zinc and boron on improvement of growth, yield and quality of tomato (Solanum lycopersicum L.) cv. Azad T-6. The experiment was layout in Randomized Block Design with three replication and 12 treatments. Treatment combinations are T0-Control (water spray), T1-Zinc (50 ppm), T2-Zinc (100 ppm), T3-Zinc (150 ppm), T4-Boron (50 ppm), T5-Boron (100 ppm), T6-Boron (150 ppm), T7-Zinc (50 ppm)+Boron (50 ppm), T8-Zinc (100 ppm)+Boron (100 ppm), T9-Zinc (150 ppm)+Boron (150 ppm), T10-Zinc (100ppm)+Boron (50 ppm), T11-Zinc (150 ppm)+Boron (50 ppm). It was found that the vegetative growth in terms of plant height and number of branches at various stages (30, 60 and 90 Days after transplanting) was greatly influenced by the application of micronutrients Zn and B. Among them treatment T5-Boron (100 ppm) significantly increased the plant height (61.23 cm at 90 DAT) and number of branches (16.17 plant−1 at 90 DAT) compared to others. Whereas, application of zinc and boron each at 100 ppm (T8) caused early flowering (31.95 DAT) as well as showed maximum number of flowers (75.21) and fruit yield (93.10 t ha−1). It was also revealed that the treatment T8 improved the physico-chemical qualities of tomato fruits specially improved the TSS:acid ratio (10.98). Thus, the study indicated that application of boron and zinc either solely or in combination is quite beneficial for vegetative growth, flowering and fruiting as well as quality improvement of tomato fruits (Azad T-6) grown under high pH soil (pH 8.2) of Lucknow.

Studies on effect of biofertilizers with chemical fertilizers on growth, yield and quality of fenugreek (Trigonella foenum-graecum L.).

The present investigation entitled studies on effect of bio-fertilizers with chemical fertilizers on growth, yield and quality of fenugreek ( Trigonella foenum-graecum L.) was conducted at the Horticultural Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.) during the years 2012-2013. Three bio- fertilizers viz., Azospirillum , PSB and Rhizobium were used at 2 levels of N, P and K as compared with control (recommended dose of NPK through chemical fertilizers) in the fenugreek. The result of all experiment showed that the maximum plant height (36.84 cm), number of branches (3.33), number of pods (7.20), days to 50 per cent flowering (66.33), days to 50 per cent germination (13.00) length of pods (8.53 cm), yield (15.57 q/ha), yield per plant (5.85 g) and days to maturity (145.26) were recorded under 50 per cent RDF+ 50 per cent Rhizobium whereas, minimum was recorded under control.
