The investigation on 'Effect of INM (Integrated Nitrogen Management) on quality of Okra (Abelmoschus esculentus L.) under Teak based agroforestry system was conducted during summer season in the years of 2019 and 2020, at College Farm (Block-A, Plot No-21), N.

during Late Kharif season in the year 2010 with mulch to study the effect of planting geometry on yield and quality of watermelon. It consists of twelve treatment combinations, comprising of three levels of planting geometry viz., diagonally paired row with 80 cm spacing (G 1), parallel paired row with 80 cm spacing (G 2) and parallel paired row with 40 cm spacing (G 3) were embedded in a Split Plot Design in CRD with four replications. The experiment resulted that with maximum yield and quality attributing characters under study were significantly affected by planting geometry treatments. Highest fruit length (21.25 cm), fruit girth (13.81 cm), yield tons per hectare (44.33 t/ha), pulp weight (1712.57 g), lowest rag weight (610.90 g), total soluble solids (10.98 °B), non-reducing sugars (3.91 %), reducing sugars (1.72 %), total sugars (5.25 %) and ascorbic acid content (7.90 mg/100 g pulp) were recorded under G 1 (Diagonally paired row with 80 cm spacing). While, superior fruit yield in terms of kg per plot (38.38 kg) was found in G 3 (Parallel paired row with 40 cm spacing).

during Late Kharif season of the year 2010 with mulch to study the effect of retention of fruits on yield and quality of watermelon. It consisted of twelve treatment combinations, comprising of four levels of fruit retention viz., 2 fruits/plant (F 1), 3 fruits/plant (F 2), 4 fruits/plant (F 3) and control (All fruits were retained) (F 4) were embedded in a Split Plot Design in CRD with four replications. The experiment result were highest average fruit weight (2.57 kg), yield tons per hectare (45.27 t/ha), maximum pulp weight (1706.56 g), total soluble solids (11.18 °B), non-reducing sugars (3.95 %), reducing sugars (1.70 %), total sugars (5.29 %) and ascorbic acid content (7.86 mg/100 g pulp) was found in case of F 2 (3 fruits per plant). While, maximum fruit length (21.29 cm), fruit girth (13.84 cm) and lowest rag weight (612.66 g) was observed in case of F 1 (2 fruits per plant). Whereas, maximum fruit yield in terms of kg per plot (36.76 kg) and number of fruits per plot (18.66) was recorded in case of F 3 (4 fruits per plant).
