Effect of Organic and Inorganic Fertilizers on Brinjal Cultivars under the Agro-Climatic Conditions of Mansehra

Abstract

The effect of organic and inorganic fertilizers on Brinjal cultivars under the agro-climatic conditions of Mansehra was studied at Agricultural Research Station Baffa Mansehra, during crop season 2011. The experiment was laid out in Randomized Complete Block Design (RCBD) with two factors having split plot arrangement. There were three treatments which includes control (No fertilizer), inorganic regime (NPK @ 100:50:50 kg ha^-1) and organic regime (Farm yard manure + Poultry manure + Mashroom waste @ 25 t ha^-1, 5 t ha^-1 and 10 t ha^-1 respectively) were assigned to main plot. Four brinjal cultivars i.e. Pusa Long, Long Black, Black Beauty and Purple Long were used as sub plot factors.  Both the growing regimes and cultivars significantly affected all the growth and yield parameters except the survival percentage of seedlings. Among the growing regimes the organic fertilizer significantly influenced most of growth and yield components of brinjal. However, minimum days to flowering (33.6), fruit set (46.6), fruit harvest (57.3) and the maximum fruit length (21.2 cm) and fruit diameter (7.0 cm) were recorded in plants grown under organic fertilizers.  The brinjal cultivars also significantly influenced most of the parameters. The cultivar Pusa Long significantly resulted in the maximum plant height (82.9 cm) and also took less number of days to flowering (37.8). While the maximum fruit length (20.8 cm), less number of days to fruit set (48.1) and days to harvest (58.6) were recorded for cultivar Purple Long. Regarding to interaction of growing regimes and cultivars, the organic regime and cultivar Pusa Long showed the best performance for most of the growth and yield characteristics of brinjal. It is concluded from the present findings that brinjal cultivar Pusa Long should be cultivated under organic regime to obtain the higher yield and maximum profitability at Mansehra, Abbottabad- Pakistan.
