Increase Crop Yield

One of the efforts to increase crop yield based in sustainable agriculture is through the utilization of microbial inoculants (biofertilizers) and soil conditioners. Biofertilizer is an ingredient that contains beneficial microbial inoculants to increase soil nutrient availability for plants. Biochar has been recognized as a soil conditioner by improving soil physical, chemical, and biological properties as well as in retaining nutrients, thereby enhancing plant growth. However, the research regarding the effect of the combination between biofertilizers and biochar on growth and yield of upland rice are still at scarce. The field experiment was conducted to determine the impact of biofertilizers and biochar on growth and yield of upland rice in Andisols at Pasir Talang village in Rancakalong district, Sumedang, West Java.  This experiment used a Randomized Block Design (RBD) consisted of six treatments and four replicates. Biofertilizers consisted of N-fixer bacteria (Azotobacter chroococum, Azospirillum sp.) and phosphate-solubilizer microbes (Pseudomonas mallei, P. cepaceae, Aspergillus niger and Penicillium sp.). The treatments were combination of biochar (2,4, and 6 t ha-1) and biofertlizers (0 and 50 kg ha-1). The result of experiment revealed that combination of biochar and biofertilizers increased the growth and yield of upland rice significantly. The application 4 t ha-1of biochar and 50 kg ha-1 of biofertilizers gave the best yield of 5,81 t ha-1.

ABSTRACT<br />Application of organic fertilizer into the soil is designated as a source of macro, micro nutrients and organic acids; it also acts as soil ameliorant that improve physical, chemical and biological properties of soil. Application of high rates organic fertilizer has a constraint namely the availability and ease of application. Therefore, it is necessary to learn the use of organic fertilizer with low rates to improve the efficiency of chemical fertilizers. This research was aimed to study the effect of organic and inorganic fertilizers on growth and yield of paddy rice, as well as the efficiency of N, P, K inorganic fertilizer. Field experiment was conducted at Sawah Baru Research Station, University Farm IPB, Bogor, West Java from September to December 2013. The experiment used Randomized Block Design consisted of two factors: rates of organic fertilizer (0, 250, 500, 750, and 1,000 kg ha-1), and rates of inorganic fertilizer (0, 100, 200, 300, and 400 kg ha-1). The results suggested that the application of 1,000 kg organic fertilizer ha-1 + 400 kg inorganic fertilizer ha-1 did not show significant interaction. Application of organic fertilizer alone up to 1,000 kg ha-1 resulted in low growth and yield. Increasing rates of  application up to 400 kg inorganic fertilizer ha-1 increased the growth and yield of paddy rice. The highest N efficiency was 89.19% at a rate of 500 kg organic fertilizer ha-1 + 200 kg inorganic fertilizer ha-1, whereas the highest efficiency of P and K, respectively were 69.55% and 92.52% at a rate of 750 kg organic fertilizer ha-1 + 300 kg inorganic fertilizer ha-1.<br />Keywords: NPK, organic fertilizer, paddy rice

Knowledge of optimum rates of poultry manure application is of immense significance in the correction of the soil nutrient deficiencies for crop production. Manure application is of importance to both the soil amendment and in the growth and yield of crops. Leaching, pattern of cropping, use of non-certified seeds and non-improved varieties have hampered the efficient growth and yield of okra. The study was conducted to examine the growth and yield responses of okra (Abelmoschus esculentus (L.) Moench) to poultry manure rates in Rivers State. The research study became imperative to examine how rate of poultry manure could affect the production of okra. The experiment utilized three rates of poultry manure, 0-tons (control), 5-tonsha-1 and 10-tonha-1and the treatment combination arranged in a Completely Randomized Block Design (CRBD) replicated three times. Growth characteristics measured were, plant height, stem thickness, leaf area and number of leaves per plant while yield parameters measured were pod length, seeds per pod, total number of pods, pod yield per hectare. The results revealed that appropriate rate of poultry manure application in the production of okra has the capacity to increase okra growth and yield in Rivers State. The use of 10-tonha-1 of poultry manure performed better than other poultry manure rates and so it’s recommended that okra farmers in the study area should apply 10-tonha-1 for high quality and quantity production of okra in  Rivers State.

High Doses

Planting shallots in Buahan Village is only carried out once a year, namely in July. The continuous use of synthetic fertilizers at high doses without being balanced with natural fertilizers has degraded the land so that soil fertility has decreased. The negative impact caused is a decrease in the yield of shallots. Quality organic fertilizers can overcome this problem. Organic vermicompost and biosllury fertilizers are quality organic fertilizers that can replace synthetic fertilizers to increase the growth and yield of shallots. The research objective was to determine the growth and yield of shallots by giving the type and dose of organic fertilizers outside the growing season. The research was conducted from March to July 2019 in Buahan Village, Kintamani District, Bangli Regency. The study used a simple randomized block design with one factor with 6 treatments, namely B0 (Without Organic Fertilizer), B1 (2000 kg / ha vermicompost); B2 (1000 L / ha biosllury) B3 (1000kg / ha vermicompost + 500 L / ha biosllury); B4 (4000 kg / ha vermicompost); B5 (2000 L / ha biosllry); B6 (2000kg / ha vermicompost + 1000 L / ha biosllury); B7 (4000 kg / ha vermicompost + 2000L biosllry) and B8 (5000 kg / ha vermicompost + 3000L / ha biosllury). The parameters observed were plant height, number of tillers, tuber wet weight per clump, harvest dry weight of tubers per clump and number of cloves per clump, soil pH, N-total (%), C-organic and total population of soil microorganisms. The results showed that the type and dose of organic fertilizer had a significant effect on all the meters observed. Treatment of 5000 kg / ha vermicompost + 3000L / ha biosllury gave the highest yield, namely 56.8 g per clump, 60% higher than the control 35.5 g per clump.

The Impact

Intercropping increases in productivity per unit of land via better utilisation of resources, minimises the risks, reduces weed competition and stabilizes the yield. Many intercropping systems have proved to be better than sole crops in terms of yield because intercropping makes better use of one or more agricultural resources both in time and in space. The beneficial effect of pulse crops is improving soil health in the form of biological nitrogen fixation, leaf fall, addition of considerable amount of organic matter through root biomass, improving microbial biomass and they keep soil productive and alive by bringing qualitative changes in physical, chemical and biological properties and sustaining productivity. The principal advantage of intercropping system is the more efficient utilization of soil, water, nutrient and increased productivity compared with each sole crop under rainfed and irrigated ecosystem. Choice of ecologically sound crops as millets and adoption of intercropping systems are two of suitable options for maximization of productivity in drylands cropping system due to the reason that competition of plant could be minimized not only by spatial arrangement, but also by combining those crops which have best able to exploit soil nutrients. A field study was scheduled to estimate the impact of intercropping varagu with greengram and blackgram cropping system under rain-fed situation onleaf area, leaf area index, specific leaf weight, crop growth rate, chlorophyll content, no. of tillers per plant and grain yield at Centre of Excellence in Millets, Athiyandal, Tiruvannamalai. It was done in Kharif, 2018 and 2019. Randomized Block Design was used to conduct this experiment. It has three replications. The aim of this study was to evaluate and compare varagu with blackgram and greengram inter cropping effects, as well as reveal which intercrops better adopts to rainfed cropping systems using these parameters to improve water use efficiency in the production. Highest returns were obtained from Sole Varagu with blackgram (1:1) due to greater productivity under this treatment with comparable cost of cultivation.
