Irrigation Method

Gemolong subdistrict in Sragen Regency of Central Java, Indonesia has a rainfed rice area of 2,047.64 hectares. Water is very limited during the dry season and this usually makes farmers use costly groundwater pumps for irrigation. This means conventional method involving the continuously flooded irrigation combined with chemical fertilizers which are considered water-wasteful and hazardous to the soil is the current practice in the area. However, water saving-irrigation with the addition of organic material has been discovered to be an alternative solution to this problem. Therefore, this study aimed to determine the effect of this method on water productivity using four variations of water-saving irrigation treatment and composition of organic application as well as one control treatment involving conventional method with chemical fertilizers. Meanwhile, composted rice straw was used as organic material and applied at 20% and 40% composition. The results showed the application of organic material boosted rice production while the water-saving method increased water productivity. Applying rice straw to the soil at 20% and 40% was discovered to have increased water productivity by 15% and 19% compared to the control treatment. Moreover, the application of 20% rice straw to water-saving irrigation method saved up to 19% water and increase its productivity by 16.5% in comparison with the control treatment. However, 40% under water-saving irrigation method reduced the water productivity by 2% even though it saved up to 27% water needed for irrigation. It is, therefore, recommended that water-saving methods added with 20% organic material be implemented as alternative rice cultivation procedures during dry season and period of water scarcity.

Rice straw is a by-product obtained from the harvest of rice. The purpose of this research is to process rice straw into organic fertilizer so it can be used as food source for fishery business. The method used is the experimental method in the field. The results of research that has been done is processing of rice straw able to produce Nitrate (NO3) and zooplankton as a source of organic material that serves as a source of food for fish so that rice straw can serve as a substitute for chemical fertilizer in the fishery business area. By using organic materials, then the fishery business results are more hygienic for consumption and can improve the fishery business.

The activities conducted in Maros regency Tanralili district Purnakarya village in chickens and beef cattle groups Cedde Jaya. The main source of livestock feed cows during the dry season are dry forage, rice straw, corn straw and hay crops of nuts which happened to be planted at the time of drought. Besides, leaf  Gamal is also a main feed in dry  season. Number of cattle per family ownership only 2-3  head extensively maintained. Range chicken as well as extensive maintenance, ownership on average 2-5 chicken each household group.  To increase the productivity of cattle, the team provides counseling, coaching, training and mentoring as well as providing some main of facilities such as cattle shed, biogas digester, planting banana. Results are expected in the presence of  activities is the avaibility of green forage mainly during the dry season, so that the cattle population will increase, the biogas as a fuel  alternative to kerosin and LPG gas, liquid and solid fertilizer from biogas by-product process, the increasing population of chicken qualified (meat and eggs as well as the day old chick).  Besides the problem of production is also done on the farm management. The activities is expected that will increase the incomes of farmers further improve the welfare of Maros regency. For the sustainability of the program it is necessary supervision and guidance are routinely performed by the related department along with the college.

The population of marginal farmers in India is bound to increase due to continued division of farm holdings. Characteristically, marginal farmers are having more family labours but the production and productivity of their land holdings is low. The foremost reason behind this is the erratic rainfall and lack of assure supplementary irrigation during long dry spells. This paper presents the scope and applicability of a diaphragm based treadle pump in Bihar where groundwater is abundant and available at shallow depths round the year. Therefore, this pump could be very useful for marginal farmers in improving production and productivity of their tiny piece of land, as it uses human power and can be operated by male and female of age group 32- 45 years and lifts water from a depth ranging from 0- 30 feet. The water saving technologies such as bucket kit drum kit etc. could be used with this pump to irrigate the crops with high water productivity.

Abstract The main objective of this study was to acquire agronomic knowledge about the effects of irrigation with saline reclaimed (RW) and desalinated DESERT (DW) water and different irrigation strategies: control full irrigation (FI) and regulated deficit irrigation (RDI) on leaf nutrients, tree growth and fruit quality and yield of almond trees in pots. Our results showed that RW had the highest concentration of some valuable agronomic nutrients such as N, but also of phytotoxic elements (Na and Cl−). Na leaf concentration on RW treatments reached toxic levels, especially under RDI, and toxicity symptoms were shown. Regarding tree growth, cumulate trunk diameter on RW-RDI was significantly lower than on the control treatment and shoot growth was reduced from the beginning of the irrigation season in RW treatments. Maximum yield was reached on RW-FI, 18% higher than the control treatment. However, RDI strategies influenced negatively on yield, being 23% less in RW and 7% less in DW although water productivity was not significantly reduced by water stress. These findings manifest that the combination of RW and RDI can be a promising future practice for almond irrigation, but long-term studies to establish suitable management practices must be developed.

The Impact

Smallholders in the tropics add different organic materials to their crops at different times, based on the availability of materials and labour. However, the time of application could have an effect on the establishment and early growth of crops, especially their root systems, which has not yet been clearly identified. This paper presents the results of a study conducted under greenhouse conditions using soils from a field treated with three organic materials at 4 or 2 weeks before or at the planting of maize seeds, corresponding to the times that tropical smallholders apply these materials. The organic materials used were leaves of Gliricidia sepium and Tithonia diversifolia or rice straw, incorporated at a rate equivalent to 6 Mt ha −1 . A control treatment where no organic matter was added was used for comparison. The impact of the treatments on soil properties at the planting of maize seed and detailed root analysis based on root lengths were carried out until the last growth stage (V4). The addition of organic matter improved the soil characteristics, and the impact of adding Gliricidia leaves was most pronounced when incorporated 2 weeks before planting. The benefits of leaves of Tithonia or rice straw on soil quality parameters were clearly evident when added 4 weeks before planting. Organic matter enhanced the root number, root length, root growth rate and branching indices. All the organic materials suppressed the growth of maize roots when applied at planting, suggesting the existence of allelopathic effects, which could result in poor growth. The most benefits in terms of root growth were observed with Tithonia .
