The case of waste from durian rind in Ngrogung, Ngebel, Ponorogo, Indonesia increased significantly per year. Agglomerations and decomposition of durian rind surrounding agro park caused air pollution and bad view in park areas. The decomposition of durian rind is very important to reduce those impacts. The micro composter model in Kampung Durian consisted of three main components. The first component was drying area with cemented ground. The drying area was set to accommodate 1 t fresh durian rind per day. The materials come from surrounding areas of agro park. The second was a machine house with one ton material capacity per day. The third was a composter house consisted of composter tube and packing area. The result of the micro composter house showed a cleaning agglomeration of durian rind from Ngebel lake and surrounding areas. In addition, the model produced liquid organic fertilizer and compost. A cycle of composting was 30 d in the dry season. Amount 1 t of durian rind decomposition resulted of 100 L liquid organic fertilizers and 50 kg compost. The result of composter had a direct impact to control waste problems in Ngebel and surrounding areas.

In 1960–65, six field trials were carried out on tea estates in Ceylon to assess the effect on yield, and on the response of the crop to fertilizer, of dieldrin sprays applied after pruning to control shot-hole borer (Xyleborus fornicatus Eichh.). Periodic sampling was carried out to assess the numbers of borers and their galleries. Yields were recorded by weekly or fortnightly weighings of the green leaf plucked, over pruning cycles of two to four years.The pattern of the yield increases on the sprayed plots was related to the difference in attack between the sprayed and unsprayed plots. Increases were, in general, small in the first year and much larger in the second year, reaching peak values of 32–58 per cent. (on the yields of successive three-monthly periods recorded) in the late second year, and declining thereafter through the third year as the difference in attack declined. Over the first two years there were marked yield increases in eight of the nine pruning cycles, and these ranged from 11·7 per cent, to 26·3 per cent. There was significant regression (P<0·001) of the percentage increase in yield on the maximum difference in gallery counts. Yield increases in the third year of pruning cycles were also considerable and the results evidence a prolonged effect of the heavy borer attack occurring in the second year.In one trial there was a significant interaction between the effects of dieldrin spraying and of nitrogen supplied. Control of the borer greatly improved the crop response to nitrogen. Nitrogen application increased the yield but resulted also in a proportionately larger loss of crop from borer attack. There was a small but significant increase in the number of borer galleries on the plots receiving nitrogen.The evidence on the size and pattern of crop losses caused by the borer suggests that these occur both from shoot breakages and from the direct effect of galleries on the growth of stems.The significance of the results in relation to estate practice, and the economics of spraying, are briefly discussed.

SUMMARYThe effect on maize yields of ground rock phosphate, alone or mixed with sulphur in either of two proportions, and of single-superphosphate, was measured at five consecutive harvests. At the first harvest single-superphosphate increased yield by 1.54 t and the best of the mixtures by 0.56 t grain/ha. Ground rock phosphate alone had no effect on yield. At the third harvest there were no yield differences between sources; because yields produced by rock phosphate and the mixtures improved. The cumulative increase in yield produced by single-superphosphate was 3.58 t/ha and by rock phosphate 2.69 t grain/ha, but because the fertilizer cost ratio was 3:1, additional grain produced by rock phosphate cost half as much. The apparent P recovery ranged from 5.40 to 8.28 kg/ha, with most from single-superphosphate and least from the mixture containing most elemental-S.

1. Some earlier work concerning the management of lucerne is discussed.2. Two experiments, designed to compare cutting and grazing the second (July) crop, and cutting and grazing the third crop at two different dates (September and October) each year on the yield and botanical composition of a lucerne-grass (mainly cocksfoot) ley, are described and the results discussed.3. The method of defoliating both the second and the third crops had very little lasting effect on yield or composition of the ley, though some temporary effects, depending on season, were found.4. It is shown that date of defoliating the third (autumn) crop of a lucerne-grass mixture may influence the yield of oven-dried produce from an individual crop. Late autumn defoliation led to a greater yield of lucerne and a greater proportion of lucerne in the produce, but since the opposite effect was found in the yield of grass there was no overall effect on the total yield of oven-dried produce over a 3-year period.5. In these experiments it appeared that lack of winter cover had no adverse effect on the productivity or persistence of lucerne in the lucerne-grass mixture studied.

This study evaluated poultry litter, commercial organic fertilizer, and compost for organic production of onion (Allium cepa) transplants within the Vidalia onion growing region of southeastern Georgia. Two field experiments were conducted. The first experiment tested six rates of poultry litter (0–10 tons/acre). The second experiment tested a factorial combination of two rates of nitrogen (N) (0 and 130 lb/acre) and three rates of compost (0, 5, and 10 tons/acre). Seedling weight, length, and diameter were measured ≈10 weeks after sowing. Poultry litter had a significant increasing linear effect on plant weight and diameter. There was also a significant increasing quadratic effect on plant length. Commercial organic fertilizer (3N–0.9P–2.5K) at 130 lb/acre N had a significant effect on plant length, but compost at 0, 5, or 10 tons/acre did not affect plant length. There were organic fertilizer by compost interactions for plant weight and diameter. There was a significant effect on plant diameter with organic fertilizer (130 lb/acre N) and 10 tons/acre compost, but there was no fertilizer effect on plant diameter at 0 or 5 tons/acre compost. The interaction effect on plant weight indicated there was a significant effect from fertilizer with 5 and 10 tons/acre compost, but not with 0 tons/acre. Based on this study, nutrition should not be a problem in producing organic onion transplants in southeastern Georgia. Four to 6 tons/acre fresh poultry litter should be adequate for producing good quality transplants. An alternative approach of using organic fertilizer at a rate of 130 lb/acre N with 5 to 10 tons/acre compost can also be used to produce good quality transplants.

Introduction: Grasses is one part of the forage, that it is necessary to support the production of grass management. The research was to determine the effect of cutting age and the use of liquid organic fertilizers (LOF) for king grass in overcoming the problem of forage feed availability. Materials and Methods: This research was conducted at the experimental field in Faculty of Agriculture and Animal Husbandry, Universitas Tjut Nyak Dhien, Medan Tuntungan Subdistrict, North Sumatra. This research used a split plot design with two factors. The main-plot was the cutting age, include T1= 35 days; T2= 45 days; T3= 55 days. The sub-plot was the different dosage of LOF, such as P0= un-fertilization; P1= 50 l.ha-1; P2= 75 l.ha-1; P3= 100 l.ha-1. The parameters were analyzed the F-test and continued with the LSD at level of 5%. Results: The cutting age significantly increased the tillers, yield of fresh matter, yield of dry matter, and storage capacity, but it had insignificant effect on the height of king grass with the highest increase was at the age of 55 days. The LOF doses significantly increased the height of king grass, tillers, and yield of fresh matter with the highest increase at the dose of 100 l.ha-1, but it had insignificant effect on yield of dry matter and storage capacity. Interaction between the cutting age with LOF significantly increase the highest of king grass height at 100 l.ha-1 of LOF + 55 days of 220.67 cm.

The study aimed to investigate an effect of organic fertilizer applied to rice in the first planting season for unfertilized soybean as second crop followed by inorganic and biofertilizer applied in the third season on soybean growth and yield under the rice-soybean-soybean cropping pattern in 2016/2017. The main plot was organic: (1) without organic amendment, (2) 10 t·ha−1 of chicken manure, and (3) 10 t·ha−1 precomposted rice straw. The subplot was inorganic N and P fertilizers and commercial biofertilizer (consisting of Rhizobium, nitrogen-fixing bacteria, and P-solubilizing bacteria) applied at planting of soybeans in the second dry season: (1) control (no inorganic and biofertilizer), (2) 50 kg urea ha−1, (3) 100 kg SP36·ha−1, (4) 50 kg urea + 100 kg SP36 ha−1, (5) biofertilizer, (6) biofertilizer + 25 kg urea ha−1, (7) biofertilizer + 75 kg SP36 ha 1, and (8) biofertilizer + 25 kg urea + 75 kg SP36 ha−1. Soybean planted on the first dry season after rice harvested was not fertilized (untreated). The results showed that the chicken manure amendment increased grain yield of soybean in the second season, i.e., from 1.03 t·ha−1 (without organic amendment) to 1.27 t·ha−1, an increase of 23%. There was no effect of rice straw on soybean grain yield. In the third season, however, the residual effect of straw compost or chicken manure increased soybean grain yield by 8% and 20%, respectively. Both straw compost and chicken manure also showed a positive effect on the use of inorganic and biofertilizers in increasing soybean productivity.

[CHLOROPHYL CONCENTRATION AND YIELD OF PAKCOY (Brassica rapa L.) AFTER TWO YEARS OF BIOCHAR AND ORGANIC FERTILIZER APPLICATION IN ENTISOLS]. While nitrogen is necessary throughout the growth of vegetable plants, N deficiency disrupts chlorophyll formation, and hence, affecting the photosynthesis process. This study aimed to study the impact of the use of biochar and organic fertilizers on chlorophyll content and yield of Pak coy mustard in the third planting season in Entisols. This research was conducted in Bawang Hamlet, Tunggulwulung Village, Malang City. The first and second planting seasons, were May-November 2017 and August 2018-January 2019, respectively. Research on the third planting season was carried out in July-August 2019 without nitrogen fertilization. The research was arranged in a randomized block design, consisting of controls (Kl), chicken manure (A), compost (K), rice husk biochar (S), rice husk biochar + chicken manure (SA), rice husk biochar + compost (SK). The results showed that after two years of application, biochar and organic fertilizers had a positive impact on the increase in yield of Pakcoy even though fertilizer was not provided. The application of biochar and compost provided the best residual effect on the total chlorophyll of Pakcoy mustard.

Au Niger Est, la faible disponibilité sur les marchés ruraux, la cherté et le faible pouvoir d’achat des paysans limitent l’application des engrais minéraux. L’objectif de cette étude est l’évaluation de l’effet du guano sur la production de la laitue. Le dispositif expérimental est un bloc complet randomisé avec dix-sept traitements issus de la combinaison entre 4 doses de guano, 2 doses de fumier et 2 doses d’engrais en trois (3) répétitions. Les paramètres étudiés portent sur les diamètres de pomme, la hauteur des parties aériennes, le développement foliaire et le rendement. Les résultats obtenus révèlent que le guano a un effet significatif sur la production de laitue. A la dose optimale 3,5 t/ha, le guano a permis d’augmenter la production de la laitue de 833 et 628% par rapport au témoin et aux parcelles ayant reçues uniquement la fumure minérale. La combinaison guano et fumure organique a permis d’accroitre le rendement par rapport aux parcelles fertilisées avec le guano seulement, tandis que l’apport de l’engrais minéral a un effet dépressif sur le rendement. Pour assurer une bonne production de laitue dans la cuvette de Balla, il serait préférable d’utiliser la combinaison guano (3,5 t/ha) avec du fumier. La préservation de la population de chauves-souris permettrait d’assurer la durabilité de la filière guano.Mots clés : Fertilisation, guano, laitue, cuvette oasienne, Gouré.   English Title: Guano, a natural organic fertilizer alternative to manure, tested on the production of green lettuce (lactuca sativa L.) in oasis of Balla (department of Gouré), Zinder, Niger In eastern Niger, low availability in local markets, high prices and low purchasing power of farmers limit the application of mineral fertilizers. The objective of this study is to evaluate the effect of guano on lettuce production. The experimental design is a randomized complete block with seventeen treatments resulting from the combination of four doses of guano, two doses of manure and two doses of fertilizer in three (3) replicates. The parameters studied for this experiment are: diameter of head, cabbage height of aerial parts, leaf development and yield. The results show that guano had a significant effect on lettuce production. At the optimum rate of 3,5 t/ha, guano increased lettuce production by 833 and 628% compared with the control and the plots receiving only the mineral fertilizer respectively. The combination of guano and organic fertilizer increased the yield compared to the plots fertilized with guano only, while the mineral fertilizer input had a depressive effect on yield. To ensure a good lettuce production in the Balla lowland, it would be better to use the guano combination (3,5 t/ha) with manure. Preserving the bat population would help ensure the sustainability of the guano industry.Keywords: Fertilizer, guano, lettuce, Oasis bassin, Gouré.
