during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Interaction effect: The interaction effect between spacing and fertilizer levels were found to be non
significant in grain yield, straw yield and economics of the treatments.
Conclusion
From present investigation it is concluded that among the different treatments, 45 cm × 5 cm spacing
was found productive and profitable as compared to 30 cm × 10 cm and found at par with 22.5 cm
×10 cm. Similarly, among different fertilizer levels application of 60:30:30 NPK Kg ha -1 found better

Dalley chilli is one of the most valued spices crops in entire Himalayan region of Kalimpong
district due to its high pungency (10,0000 to 35,0000 SHU) and taste. The crop is generally
grown during the period of middle of March to first week of July. During the growth period,
prevailing of unfavourable condition such as heavy rainfall, water stagnant, frequent leaching
loss of micronutrient from soil resulting to micro-nutrient deficiency, excessive weed growth and
heavy infestation of pests and diseases hampers the crop growth and yield. Polymulching is one
of the novel approaches for horticulture as it reduces soil moisture loss, suppress weed growth,
increases radiation and water use efficiencies which directly effect on crop yield. Therefore, a
study on the impact of polymulching was conducted at NICRA adopted village Paiyong, under
Krishi Vigyan Kendra of Kalimpong during the year 2022 with an objective to enhance the
production of Dalleychilli with maximum returns to the farmers. Finding of the trials suggests
