Nutrient scheduling for upland rice intercropped in coconut
Journal of Crop and Weed, 2018
Field experiment was conducted at Coconut Research Balaramapuram, during Kharif 2017 to study the effect of nutrient levels and schedule of nutrient application on the yield and economics of upland rice intercropped in coconut. The experiment was conducted in RBD with four different nutrient levels and four different schedules of nutrient application. Nutrient levels significantly influenced the grain and straw yield, net returns and B: C ratio and the highest grain yield, straw yield, net returns and B: C ratio were recorded with the application of NPK @ 90:30:45 kg ha-1. Nutrient schedules also have significant effect on grain yield, net returns and B: C ratio. Among the schedule of nutrient application, N applied in three splits (15 days after sowing (DAS), active tillering and panicle initiation stage), P as basal and K in two equal splits (15 DAS and panicle initiation stage) along with foliar application of 0.2 per cent zinc sulphate and 0.04 per cent sodium borate recorded the highest grain yield, net returns and B:C ratio. Interaction between nutrient levels and schedule of nutrient application was also found significant. NPK @ 90:30:45 kg ha-1 , applied as N in three equal splits (15 DAS, active tillering and panicle initiation stage), P as basal and K in two equal splits (15 DAS and panicle initiation stage) along with foliar application of 0.2 per cent zinc sulphate and 0.04 per cent sodium borate at 45 DAS recorded higher grain yield, net returns and B:C ratio and can be recommended for upland rice raised as intercrop in coconut.

The need to maximize farm productivity through efficient use of light energy and soil resource is necessary in attempts to increase food production and mitigate climate change. This study evaluated the productivity of traditional upland rice and legume intercrops planted singly and in combinations under a coconut-based farming system. A split-plot design composed of two factors with three replications was used. The main plots were traditional upland rice varieties (Kalutak, Malido, Mansanaya, San Pedro, and PSB Rc 10 as check variety) while sub-plots were legume intercrops (peanut, mungbean, soybean, and no intercrop as control). Growth and yield of crops and return on investment (ROI) were gathered to determine productivity. Results revealed that Malido with no intercrop produced the tallest plant, while most tillers were from plots without intercrop. Highest dry grain yield of rice (1.42 t ha-1) was taken from plots grown to San Pedro with no intercrop. Highest dry grain yield of legumes was from plots with Mansanaya + soybean (0.94 t ha-1) and PSB Rc 10 + mungbean (0.92 t ha-1). Highest ROI (344.40%) was from plots with PSB Rc 10 + mungbean.

Rice is the staple food for eastern India as well as for more than half of the world’s population. It influences the economics and livelihood of several billion people. Medium and low lands are predominant in this part of the country where farmers have no other option but to go for rice cultivation. Yield stagnation and yield plateauing due to aberrant climatic condition with high yielding rice varieties is one of the major constraints to achieve future need for rice production.

Excessive use of inorganic fertilizers is a major concern in paddy fields which has deteriorated soil health extensively for which a shift towards integrated nutrient management (INM) is the opt choice to feed the growing population. Therefore, a study was conducted at Agricultural College and Research Institute, Madurai, Tamil Nadu, India during 2021 to assess the effect of INM on the phyllochron and tillering in rice. Recommended rates of organic manures viz., farmyard manure (12.5 t/ha), green leaf manure (5 t/ha), poultry manure (5 t/ha), goat manure (5 t/ha) and vermicompost (5 t/ ha) were integrated with recommended dose of fertilizer @ 150: 50: 50 kg/ha NPK. Study revealed that INM through farmyard manure resulted in increased growth (plant height, total leaf area, more of leaves and tillers per plant) in lesser accumulated thermal time (21.2 °C days/leaf) required for leaf emergence @ 0.646 leaf/day. Therefore, it is evident that combining inorganic fertilizers with organic manures could enhance the growth and facilitate steady nutrition to the rice crop in addition to improved soil health over conventional method of cultivation.

Population explosion is now a days a major factor that affects the food production in our country and thus quality food grain production in enough quantity without damaging the soil quality, productivity and fertility is one of the biggest challenges in the present agriculture scenario. Now a days, application of huge amount of chemical fertilizer, pesticide, growth hormone etc. are becoming mandatory to achieve the production requirements and also to meet the food demand. But this faulty method not only decreases the soil fertility, but also pollute the environment and hamper the soil ecosystem and biodiversity. This situation is very prominent in case of rice cultivation area where huge quantity of chemical fertilizers are used. So, to overcome this problem INM is one of the emergent approaches that can minimizes the heavy use of chemicals and in other hand, maximize use efficiency and improve the soil health. Combined effect of both essential and beneficial nutrient elements and also effect of different plant growth promoting substances in plants can be fulfilled completely by judicial and proper Integrated Nutrient Management practice. Rice (Oryza sativa L.) is an important cereal crop and grown across the world. Most of people of the world depend on rice for their secured livelihood and a way of life. It is the staple food for more than 65 per cent of the people and provides employment and livelihood to 70 per cent of the Indians. There is a need to enhance the sustainable productivity of the rice to meet the growing demand under conditions of declining quantity and quality of land with special reference to INM.Changing in cropping sequence with respect to availability of resources the integrated approach of nutrient supply through inorganic and organic has become very much promising in building soil health and quality of produce and meeting the food security.

The results of the experiment revealed that rice seed production plots treated with the combination of T11-GM+100:50:50 + ZnSO4 @ 25 kg ha + Borax @ 4 kg ha recorded the highest seed yield of 4.05 t ha–1 which was 4.11% more yield (3.89 t ha–1) than the treatment T10– 100:50:50 + ZnSO4 @ 25 kg ha + Borax @ 4 kg ha.
Effect of Nutrient Solution on Yield and Quality of Rice
A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University experimental farm during August to November 2010 to observe the effect of full recommended doses of fertilizer (RDF) alone and in combination with 1000, 3000 and 5000 times diluted nutrient solution together with 50 and 75% RDF on the yield and quality of rice (BR 11). The highest grain yield of 4.42 t/ha was obtained due to the cumulative effect of maximum number of tillers per hill, panicle length (cm) and1000 seed weight (g) on the other hand total soluble solids (brix value), protein, ash, ascorbic acid and β-carotene contents in rice were the highest where 1000 times diluted nutrient solution was added along with 100% recommended dose of fertilizers. Treatment receiving thousand times diluted nutrient solution along with 75% RDF also showed similar results in most of the parameters of the crop studied.
