India is considered to be the largest producer of sapota in the world. The major sapota producing states in India are Karnataka, Maharashtra, Gujarat, Andhra Pradesh and Tamil Nadu.An application of major and micronutrients through foliar sprays provides one of the best tool for immediate food requirement of plants. An application of micronutrients resulted in enhancement of physiological parameters and better nutrient contents in leaf of sapota. The physiological parameters like photosynthetic rate, stomatal conductance and transpiration rate were increased with higher level of micronutrients i.e. FeSO4 2% + ZnSO42% + borax 1% (T10). However, leaf temperature was not influenced significantly by foliar spray of micronutrients. Regarding leaf nutrient status, iron, zinc and boron contents were found higher with same treatment (FeSO4 2% + ZnSO4 2% + borax 1%) (T10) in sapota leaves as compared to other treatments.Keywords

Fertigation, splitting and mulching are an essential tools in precision farming and that effectively affected in physiological, growth attributes, yield and quality parameters as well as nutrients content in leaves. Joint use of fertigation and mulch resulted in comparable growth and yield as unmulched condition and saved in fertilizers and irrigation water. Mulches maintain the soil temperature, retard the loss of soil moisture, suppress of wood growth, conservation of soil from erosion, reduction of soil salinity, improvement of soil structures, improve water infiltration rate by creating hindrance in flow of water, control of pest and diseases and enhance microbial activity in the field. The total dry matter (TDM) production and leaf area index were significantly higher in drip irrigation. Water-soluble fertilizer (WSF) fertigation recorded significantly higher total dry matter and LAI over drip irrigation. Chlorophyll concentration was significantly higher in fertigation treatments over soil applied treatments. The fruit yield in fruit crop was higher in drip irrigation over furrow irrigation. Fertigation with 100 per cent WSF increased the fruit yield significantly over furrow-irrigated control and drip irrigation. Fertigation resulted in lesser leaching of NO3-N and K to deeper layer of soil. Subsurface drip fertigation caused higher assimilable P in deeper layer.
