Mono-granular Compound Fertilizer Acting Slow Release for the Crops Under Vinyl Mulching Cultivation -II. Effect of newly developed compound fertilizer on red pepper

비닐멀칭 작물재배용(作物栽培用) 지효성(遲效性) 전용복비(專用複肥) 개발(開發) -II. 고추 전용복비(專用複肥)의 비효시험(肥效試驗)

Two trial products of monogranular compound fertilizer for red pepper under vinyl mulching cultivatin were made using the principal sources of urea, diammonium phosphate and muriate of potash in combination with fillers of treated human wastes (product I) and zeolite (Product II). A field experiment was carried out to evaluate their effects on red pepper and the results obtained were as follows. Red pepper plant growth and total red fruit yields in the trial products of one time basal application were better and higher than those of NPK split application of contrl plot. The increases of yield in the trial products might be due to steady supply of nutrients for the entire growing period. Therefore, one time basal dressing of a developed monogranular compound fertilizer for red pepper was applicable under vinyl mulching cultivation.

요소(尿素), DAP, 증화가리(增化加里)를 주재료(主材料)로, 분뇨잔사(糞尿殘渣)와 Zeolzte를 부재료(副材料)로 활용(活用)하여 제조(製造)한 고추전용복비(專用複肥)인 시제품(試製品) I II를 비닐멀칭재배(栽培)로 비효시험(肥效試驗)을 실시(實施)한 결과(結果)는 다음과 같다. 가. 고추의 초장(草長)과 간경(幹徑)은 시제품(試製品)II구(區)가 대조구(對照區) (NPK분시구(分施區))에 비해 좋았다. 나. 고추의 총적과수량(總赤果收量)은 시제품(試製品)II구(區)가 가장 증수(增收) 하였으나 대조구(對照區)에 비해 통계적(統計的)인 유의성(有意性)은 없었다. 다. 개발(開發)된 시제품(試製品)은 비닐멀칭조건에서 고추재배(栽培)를 위한 전량기비용비료(全量基肥用肥料)로서 가능(可能)하였다.
