Nutrient classification in soil, leaf nutrient content and yield of combination of red and yellow (Prunus aremeniaca L) as influenced by drip fertigation and unoriginal fertilization accompanying water soluble fertilizers were evaluated through field tests for three years on ‘Incepstisols’ at Nauni, Solan, Himachal Pradesh. The refined variety of combination of red and yellow was New Castle. Drip fertigation with 100, 75 and 50% recommended measurement (RD) each of conventional manure (CF) and water-soluble fertilizers (WSF) besides conventional soil breeding both under irrigated and rainfed environments were tried in trio. Iso-moisture curves were developed to decide the water distribution pattern under trickle irrigation. The results demonstrate that lower insights (30-45 cm) under conventional watering registered much higher water content distinguished to drip watering. Similar trend exhaustive-wise distribution of water at various lateral distances from emitters was noticed under drip and conventional watering system.The plurality of the applied minerals during fertigation remained in the surface coatings, whereas N and K transported to lower depths under soil fertilisation plus irrigations. The NO3-N concentration in the superior soil layers was bigger with trickle fertigation than with conventional soil fertilisation, meaning higher draining losses with the latest. The NO3-N content was low beneath the emitters and evolved with growing lateral distance from the emitter up to 15 cm before lowering. The NH4-N concentration was better under the emitters and lowered both across and laterally. When drop fertigation was used instead of soil fertilisation, the leaf mineral content was higher. Fertigation presented significantly more combination of red and yellow fruit weight and yield than soil fertilisation. Drip fertigation accompanying WSF resulted in a larger fruit yield than CF. The regression study of data on crop yield and tried fertiliser levels disclosed that the optimum levels for CF and WSF for drip fertigation were 67 and 70% of RD, individually. Thus, fertigation could sustain approximately 30% of the fertilisers used. The results finally proved that trickle fertigation holds a great potential because it improved the fruit amount and weight of combination of red and yellow significantly over soil fertilization accompanying conventional surface watering.
