Effect of bio-fertilizers on growth and yield of spinach (Beta vulgaris L.) cv. All Green

Abstract

Spinach beet is one of the most common leafy vegetables of tropical and sub-tropical regions. The popular palak growing states include Uttar Pradesh, West Bengal, Maharashtra and Gujarat. However, Palak is not very popular in South India. It is primarily used as potherb. It is a rich Source of vitamin A and C and also contains appreciable amount of protein, calcium and iron. The leaves contain low oxalic acid. Variety All Green was developed at the Indian Agricultural Research Institute, New Delhi, it produces green tender leaves and gives about 6-7 cuttings at 15-20 days interval with yields about 12 tonnes/ha. Bio-fertilizers are less expressive, ecofriendly and sustainable likely to assume greater significance complement or supplement to inorganic fertilizers. A field experiment was conducted to see the effect of biofertilizers on growth and yield of spinach. Under study treatments imposed were Control – RDF (T0), Azotobacter @ 10kg/ha (T1), PSB @10 kg/ha (T2), Azotobacter + PSB each @10 kg/ha (T3), Azotobacter + PSB as seed treatment (T4), Azotobacter @ 2 lit/ha (T5), PSB @2 lit/ha (T6), Azotobacter+ PSB each @2 lit/ha (T7),Azotobacter @10 kg and PSB @2 lit/ha (T8), Azotobacter @ 2 lit + PSB @ 10 kg/ha (T9). Result revealed that biofertilizer supplimentation beneficial over control with respect to growth and yield of crop. Among biofertilizers of Azotobacter and PSB each at 2 litre per hectare application through liquid formulation was better and economic to the farmers for growing spinach cv. All Green.

Influence of Varieties and Nutrient Levels on Growth, Yield and Profitability of Palak (Beta vulgaris var. Bengalensis)

“…The more availability of nutrients under higher levels might have encouraged the photosynthesis, accumulation of food material and higher plant growth resulting in more plant height. These results are in accordance with the findings of Ali et al [10], Singh et al [11] and Hashimi et al [12].…”

Effect of the Interaction of Nutrient Sources on the Growth, Yield and Quality of Tomato (Solanum lycopersicum L.)

“…These findings are in line with the findings of Wange et al [8] and Tripathi et al [9]. The increase in yield might be due to increased fruit set per plant, due to the fact that nitrogen fixers and phosphorous solubilize not only increased the availability of nitrogen and phosphorous to the plants but also increased their translocation from root to flower through plant foliage [10]. Similar results were reported by Mirza Khan et al [11] in safflower and Poonia and Dhaka [12] in tomato.…”

“…These results are consistent with those of Wange et al [8] and Tripathi et al [9], who found that applying Azotobacter and PSB increased strawberry yield. While nitrogen fixers and phosphorus solubilizers boosted the availability of nitrogen and phosphorus to the plants as well as their transfer from root to flower through plant foliage, the rise in yield may be attributable to an increase in fruit set per plant [10]. Similar findings in safflower and tomatoes were reported by Mirza khan et al [11] and Poonia and Dhaka [12], respectively.…”

Impact of bio-fertilizers on growth, yield and quality of Spinach (Spinacia oleraceaL.) in Noida UP.

“…The International Council on Medical Research (ICMR) states that an individual needs between 50 and 60 grammes of leafy vegetables per day. Our country produces about 19.7 tonnes per hectare, a significant decrease from other wealthy countries like Spain, whose production is 39.3 tonnes per hectare [7]. When growing baby spinach, organic fertilisers such farmyard manure, goat and chicken dung, and biofertilizers can take the place of chemical fertilisers [8].…”
