Continuation Winter irrigation ******** 1.Nursery 38 ROBUSTA BEARING PLANT Gentle sloping land without big shade trees is preferred for raising nurseries. Water should not stagnate in the nursery sites. Stagnant water near the nursery beds 38
39 cause rotting of seedlings. Suitable water resource should be available near the nursery for timely watering of the nursery beds and seedlings. Any shade trees near the nursery will damage the young nursery seedlings in the beds and poly bags due to water dripping from them. For sowing the coffee seeds, germination beds of 1 metre width and of convenient length raised to a height of 15 cm from the ground level should be prepared. About 4 bags (10Kgs) of matured farm yard manure or compost well dried under sun light be mixed with 2 Kgs of fine Agricultural lime and 0.5 Kgs of Rock Phosphate and thoroughly incorporated in the nursery beds measuring 1X6 metres. In the nursery high clay content should not be used as they restrict the air circulation causing damage to the sprouting seeds. If one is using the clayish soil, then it should be mixed with coarse sand properly to enable easy air circulation. Any deficit air circulation in the nursery soil will cause stunted unhealthy development of the seedlings sometimes resulting in death of the seedlings. The nursery sites should be totally free from nematodes. Therefore, it is advised and recommended that before preparing the nursery, the soils of the nursery site as well as the soils to be used to prepare the nursery beds should be tested in the laboratories for the presence of nematodes. One should note that the compost/farm yard manure used in the nursery should be free from cockchafer pests. Selected and certified seeds can be sown during December or January in the nursery beds. The seeds be sown with their flat side facing the soil which helps early germination and easy rooting in the soil. After sowing, the seeds are covered with a thin layer of finely sieved soil and mulched with a layer of paddy straw which ensures optimum temperature for seed germination and protects the seeds from desiccation. If paddy straw is not available, any kind of other grass materials can be used for mulching. The beds are then daily optimally watered in the morning hours with rose cans. The seeds will germinate in about 40-45 days and attain button or topee stage. Once this stage is reached the mulch covering the beds should be carefully removed without damaging the germinated seeds. The seedlings at topee or button stage can be then transplanted into either into poly bags or in the secondary nursery beds as the need may be. 2. Robusta coffee harvesting To maintain and protect the coffee beverage quality, aroma, thickness of the brew, taste and flavour as well as acidity in the cup, the right kind of coffee fruits have to be harvested in right time following certain suggested guidelines. Improper harvesting will result in spoiling the cup quality even if the coffee plants are known to belong to top quality category. Therefore, following the right kind of harvesting procedure will help in protecting the inherent quality as well as helps in getting premium prices. Coffee fruits have to be picked as and when they become ripe; this can be understood by gently squeezing the fruit with fingers. On gentle squeeze, the bean inside the fruit pops out easily. Under ripe or over ripe fruits should not be mixed or used for the preparation of parchment coffee as they can spoil the overall cup quality. The under ripe coffee fruits result in the production of immature beans and the over ripe ones cause foxy coffee resulting in brown beans with fruity cup. If the harvest is not possible as and when fruits rightly mature, the under ripe and over ripe fruits needs to be separated from the lot and only right kind of desired fruits have to be pulped in the course of preparation of parchment coffee. 39
