บทคัดย่อ (EN): Hevea brasiliensis (natural rubber) forms the basis of one of the most important agricultural industries in the Indian economy. The lengthy gestation period of rubber is a major deterrent among the rubber growers to new planting and replanting. The extent of gestation period of natural rubber is mainly governed by the inherent clonal characteristics. Type and quality of planting materials used edaphic and environmental factors, agro-management practices adopted and biotic and abiotic stresses. This paper is focused on the results of a field experiment conducted with an objective to develop an agronomic package to reduce the immaturity period of rubber. The effect of different agro-management practices on enhancing the growth and reducing the immaturity period of rubber (clone RRII 105) was evaluated individually and in combination (integrated management) in a field experiment conducted at Malankara estate, Thodupuzha, representing the traditional rubber growing region in India. The treatments comprised of current recommended practice; irrigation, i.e irrigating the plants during summer months at 50% of the water requirement for the initial three years; enhanced nutrient application i.e pit manuring @ 500 g bone meal per plant, application of 1.5 times the recommended dose of fertilizers in four splits and 10 kg FYM, 500 g bone meal and 500 g groundnut cake as top dressing for the initial four years; selective manuring i.e. application of an additional dose of 1.5 times the recommended dosage of fertilizers in three splits to the weak plants for the initial four years; conservation oriented tillage i.e. forking the plant basin followed by heavy mulching and taking conservation pits @ 250 per ha; irrigation + enhanced nutrient application; integrated management which included irrigation, enhanced nutrient application, selective manuring, and conservation-oriented tillage. The individual plot size was 24 plants with a net plot size of six. Observations on growth, soil moisture storage, leaf area index and soil and leaf nutrient status were recorded and disease assessment was done periodically. The results of the experiment indicated that growth of plants under integrated management was significantly superior to others throughout the experimental phase followed by the treatments irrigation enhanced nutrient application and irrigation which were on par. The effect of different agromanagement practices was reflected in the leaf area index. The mean LAI recorded at the centre of four plants at different times was the highest for integrated management, followed by irrigation enhanced nutrient application and irrigation which were comparable. Soil moisture storage during summer also followed a similar trend. A significantly higher soil moisture content was retained by the treatments integrated management, irrigation enhanced nutrient application and irrigation. The soil and leaf nutrient status did not vary significantly among treatments. The incidence of pink disease was moderate. However, treatmental variations in pink incidence were not observed. The individual effect of mulching, tillage, conservation pit and organic manure addition on improving soil moisture storage and enhancing growth of the plants is well documented. Mulching is an important agronomic practice in rubber plantations to conserve soil moisture, protect the soil around the base of plants from direct impact of heavy rains and sunlight causing soil degradation. Silt pits are one of the efficient runoff management techniques wherein a part of the runoff is conserved and reused for crop production in a sustainable manner. Earlier studies showed that split application of fertilizers and the use of increased rate and frequency of fertilizer application also contributed towards enhanced growth and thereby reducing immaturity period. Irrigation during summer also enhances the growth of the plants. All these good agricultural practices contributed towards the increased growth of the plants under integrated management and 72 per cent of the trees under integrated management achieved tappable girth in a period of five years and nine months compared to the normal gestation period of seven years in the traditional belt. The results of the experiment clearly indicate the feasibility of substantially reducing the immaturity period through the adoption of improved agromanaement techniques.
