| Experiment Background | Sapota [Manilkara achras (Mill.) Fosberg] is common name denominating a popular evergreen and ever fruiting tropical fruit tree of the family Sapotaceae and the order Ericales. It is one of an important fruit crop of the tropical region. It is an exotic tree introduced from tropical America and commonly referred to as Chiku in many places of India which is also known by several names including chico, sapodilla, naseberry, lamut, chicle, etc. In India, it is cultivated for its delicious fruits of exclusive quality, timber and latex. It occupies about 97.3 thousand ha area with 1175.9 thousand MT production and 12.1 MT/ha productivity in India. Gujarat has emerged as the first largest sapota producing state followed by Karnataka and Tamil Nadu. The state occupies about 29.55 thousand ha area and 326.36 thousand MT production with 11.04 MT/ha productivity. Navsari district has 8.13 thousand ha area and 102.89 thousand MT production with 12.65 MT/ha productivity (Anon., 2018). Silicon is one of the beneficial element can helps in improving growth of plant by correcting their deficiencies especially in highly weathered soil. Silicon is considered as an important beneficial element as it helps in growth and development of plant. It has positive growth effect including increased dry mass and yield, enhanced pollination and most commonly increased disease resistance (Gillman et al., 2003). It is also known to increase drought tolerance in plants by maintaining plant water balance, photosynthetic activity, erectness of leaves and structures of xylem vessels under transpiration rates. Effects of silicon on yield are related to the deposition of the element under the leaf epidermis which results a physical mechanism of defence, reduces lodging, increases photosynthesis capacity and decreases transpiration losses (Korndörfer et al., 2004).Potassium silicate is a source of highly soluble potassium and silicon. It is used in agricultural production systems primarily as a silica amendment and has the added benefit of supplying small amounts of potassium. In many horticultural crops, an adequate potassium nutrition also contributes in enhancing tree yields, fruit size, fruit colour, soluble solids, ascorbic acid concentrations, shelf life and also improved shipping quality (Kanai et al., 2007). | ||
