control plot. Progressively, it was increased (4244, 5470 kg ha -1 ) in treatment T1receiving suboptimal
fertilizer dose 50% NPK. The results also indicated that even if 50% NPK of the
recommended optimal dose was applied was found much more beneficial in comparison to the
application of imbalanced nutrient application. Similarly, it was also found that 100% N
treatment (T7) resulted in 1779 and 5350 kg ha -1 grain and straw yield of wheat. It was
progressively increased when P and Knutrients were included in fertilizer schedule.

Pran (Allium x cornutumClementi ex Visiani) is a triploid viviparous species of genus Allium,
extensively grown in Kashmir from times immemorial (Singh et al., 1967, Klaas and Friesen
2002). Pran is a cool season spice crop which grows well in mild climatic conditions. Being a
long duration, rainfed and less labour intensive, this crop is cultivated on lofty hills where
irrigation facilities seldom exist. It is more cold-hardy than onion and tolerates frost to a greater
extent. Pran is traditionally cultivated in Kashmir and it is very popular as a spice and condiment
due to its tasty bulbs and leaves. It is highly relished in Kashmiri kitchens in the preparation of
soups, meat and salads. In the absence of scientific information with regard to appropriate
nutrient dosage, spacing and bulb size for propagation in pran, it is difficult to reckon and realize
the objective of higher yield. The present investigation was carried out to find the appropriate
nutrient dose, bulb size and spacing for yield maximization in Pran.
Methodology
The experiment was conducted in two successive years and laid out in random block design with
27 treatments and 3 replications as detailed below. Three factors viz., NPK, spacing and bulb size
were taken for evaluation, each at three different levels forming 27 treatment combinations.
